Пружина с постоянна сила, приложена към спирачката за дистанционна хирургия

Час: 2022-9-14

Минимално инвазивната медицинска технология се използва за намаляване на броя на чуждите тъкани, които могат да бъдат увредени по време на диагностика или операция, така че да се намали времето за възстановяване, дискомфорта и неблагоприятните странични ефекти на пациентите. Хирургът може да управлява контролера на конзолата, за да управлява индиректно инструмента, свързан към дистанционно управлявания задвижващ механизъм. Инструментът може да бъде разглобен от дистанционно управлявания задвижващ механизъм, така че инструментът да може да бъде дезинфекциран отделно и избран за използване като инструмент, необходим за операция. Комбинирайте. Инструментите могат да бъдат сменени по време на операцията. Използването на дистанционни инструменти за хирургия носи нови предизвикателства. Един проблем е да се осигури дистанционно управляван моторен механизъм, който поддържа дистанционно управляван задвижващ механизъм, който може да бъде позициониран спрямо пациент. Тези елементи са доста тежки и могат да тежат между 12 и 24 килограма. Механизмът трябва да бъде преместен над пациента и внимателно позициониран. Следователно е необходимо да се балансират хирургическият инструмент, свързаният задвижващ механизъм и поддържащата структура, така че хирургическият инструмент да може да бъде позициониран безопасно и лесно. Пружината с постоянна сила е направена от лента от неръждаема стомана, така че когато се навива спрямо разтегнатата, пружината ще се отпусне в състояние на ниско напрежение. Когато се разгъне, възстановяващата сила идва главно от частта близо до разхлабената намотка на пружината. По-конкретно, силата идва от областта, която преминава от кръг към равнина. Силата не идва от частта на барабана, която е напълно разгъната или все още се навива. Получената сила е почти постоянна, защото геометрията на тази област...

Приложение на пружина с постоянен въртящ момент в 3D принтер

Час: 2022-9-14

3D printing, also known as three-dimensional printing, is a kind of rapid prototyping technology. It uses adhesive materials such as powdered metal or plastic to construct zero objects through multi-layer printing layer by layer. Mold making, industrial design is used to build models, and is now developing into product manufacturing, forming "direct digital manufacturing". Some high-value applications (such as hips or teeth, or aircraft parts) already have printed parts. The constant torque spring is applied to the 3D printer. This innovative case is a spring motor drive system. Like the common design, it is impossible for a spring to achieve the torque we need. As you can see we are using three constant torque springs in one mechanism with an output drum in the middle connecting the three springs. Therefore, it can generate three times the output torque of only one spring, and this design can achieve the purpose of providing maximum torque in a limited space. This connection method is easier to assemble than using screw connections.        When it comes to spring design, design engineers must consider many factors. These factors include not only part function and mechanism design, but also detailed material selection, part connection installation method and size. It's all about manufacturability. Feasibility analysis is required to ensure the functionality meets the customer's needs.        From the initial design stage of the spring set to production and final assembly, Qianye can save customers product development time, find optimized solutions beyond your expectations, no manufacturability constraints in product design, and the best product...

 With the development of society, buildings and roads are the cornerstone of the development of human society. People will choose to lay waterproof materials during waterproof maintenance, but people face some problems when laying waterproof materials. When laying waterproof materials, people inadvertently trample on the materials because they do not know that the materials have been laid, resulting in uneven laying of materials and economic losses. Therefore, we need to protect the sites under construction and just completed construction when laying. Many of the existing protective devices are large, which is not conducive to people's carrying, and the protective devices can't be seen by people at night, causing people's damage. The laying of water-proof materials is wasted, and the placement of protective devices is unbalanced, causing collapse and damage to people.   The utility model relates to a wet laying waterproof coiled material construction protective device equipped with a power spring, which can solve the above problems. The power spring requires a housing to limit its outside diameter. The spring stores force during the rotation of the power spring relative to the central axis of the spring housing. When the force disappears, the power spring will produce a torque on the central shaft of the spring housing.   The protective device comprises two expansion columns 1, a contraction device 21, a second fixing block 4 and two expansion columns 1, one of which is provided with a contraction device 21. The retracting device 21 is composed of two rotating discs 12, the first fixed column 13 and the power spring 14. The rotating disc 12 is installed in the...

A draw-wire encoder, also known as a string potentiometer, pull wire position sensor, cable extension displacement sensor, or yo-yo potentiometer. It is a cable driven position or displacement sensor for linear position measurement and velocity using a flexible cable (wire) and a spring loaded spool.   The string pot or cable extension sensor is composed of four main components in the shell: 1. High strength stainless steel cable (rope or steel wire rope); 2. Equal diameter spool (drum); 3. Power spring with high torque and long service life; 4. Rotary potential precision sensor.   In the shell of the sensor, a soft high-strength stainless steel cable is tightly wound on a precision machined cylindrical drum (or spool) with constant diameter, which rotates with the winding and unfolding of the measuring cable. In order to maintain the tension and retraction of the steel wire, the spring is connected to the drum. Then connect the spool to the shaft of the rotary potential precision sensor (or encoder). When the sensor string extends linearly with the moving object, it will cause the roller and sensor shaft to rotate.   For displacement or position measurement, the main body of the sensor is installed on the fixed surface, and the end of the flexible cable is connected to the moving object. When the object changes its position, the cable unfolds and reels and the rotating spool drive the shaft of the sensing device, generating an electrical signal proportional to the linear extension or displacement of the cable. For speed measurement, a tachometer is required. The power spring is mainly used in the equipment of...

The electric roller shutter has many advantages, such as beautiful and simple appearance, firm and durable structure, etc. the roller shutter is suitable for a variety of places, such as business office buildings, hotels, restaurants, offices and homes (used as gauze curtain), especially for large-area glass curtain walls. When the roller shutter fabric is put down, it can soften the indoor light, avoid the trouble of direct sunlight, and achieve a good sunshade effect. When the roller shutter is raised, its volume is so small that it is not easy to be detected. Have you ever thought about why the roller shutter will automatically rise and fall, and can freeze at any position without running up or down? You may not have an in-depth understanding, because the addition of variable force spring makes the electric roller shutter achieve this effect. The electric roller shutter extends from the longest to the shortest, and the weight of the lower beam changes from light to heavy. Therefore, the elastic force of the variable force spring needs to gradually increase from small to large, reaching the full stroke and gravity balance. So that the curtain can stop and hover at any position. Many variable force springs on the market can not reach the variable force spring whose force is changing at any section, so many electric roller blinds will add some components (deceleration device, damping device, gear device, limit device, etc.) to achieve the effect of perfect lifting, free positioning and free pause. Qianye often contacts with some foreign curtain industries, especially in cordless curtains and roller blinds, which...

Nine factors that should be paid attention to in spring production

Час: 2022-9-14

A spring is a mechanical part that works with elasticity. Generally made of spring steel. It is used to control the movement, buffering or vibration, energy storage, force measurement, etc. of mechanical parts, and is widely used in machines and instruments. (1) Elastic limit - the elastic limit is related to the tensile strength. Selecting a material with a high elastic limit is usually equivalent to selecting a material with a high tensile strength. (2) Spring coefficient - the stress applied to the spring material to produce a unit strain is called the elastic coefficient value, which mainly depends on its chemical composition.    (3) Fatigue strength - fatigue strength must be considered for springs subjected to dynamic loads.   There is a certain relationship between fatigue strength and tensile strength of materials. (4) Hardenability - in order to improve the quenching effect, the material is required to have good hardenability, and at least 50% of the central block iron structure shall be quenched. (5) Shape and size - the mechanical properties of the spring material change with the size. The manufacturing size of the spring material is allowed to have tolerances. Therefore, the material must be selected according to the accuracy of the spring load characteristics.(6) Heat resistance - some springs are used at certain high temperatures. Generally, the mechanical properties of spring materials decrease with the increase of temperature, and the spring performance decreases after a certain temperature.   (7) Corrosion resistance - when the spring is used in a corrosive environment, the corrosion resistance of the material mainly depends on its chemical composition.    There are many corrosion factors, so we...

Час: 2022-9-14

Предпазният колан е равен на спасителния колан. Всеки трябва да види болезнените инциденти, причинени от липсата на предпазен колан. Вярвам, че всеки е запознат с автомобилния колан. Това е предпазно устройство, за да се избегне бързо излизане от колата по време на сблъсък и причиняване на смърт и нараняване. Автомобилният предпазен колан е признат за най-евтиното и най-ефективно устройство за безопасност и също така е необходима конфигурация за безопасност. В типична система за предпазни колани, предпазният колан е свързан с прибиращо устройство. Основният компонент на прибиращото устройство е макарата, която е свързана с единия край на предпазния колан. Вътре в прибиращото устройство, с помощта на действието на силовата пружина, лентата може да се разширява и свива свободно с движението на тялото на потребителя, без да разхлабва лентата. В случай на аварийно спиране, сблъсък или рязка промяна на състоянието на движение на превозното средство, чувствителният елемент в прибиращото устройство ще заключи макарата, за да фиксира лентата в определена позиция и да понесе натоварването, наложено върху лентата от тялото на потребителя. Силовата пружина е изработена от валцована стоманена лента. Необходима е пружинна кутия, за да се ограничи външният й диаметър при използване. Центърът на пружината е свързан с вала. Когато се приложи външна сила, за да накара вала да се върти спрямо пружината, пружината ще се търкаля в центъра на вала и ще съхранява въртящ момент. Когато външната сила изчезне, пружината ще създаде въртящ момент върху вала или пружинната кутия. Qianye направи технически актуализации на продукта за електрически пружини.

Предварителна топлинна обработка на пролетта

Час: 2022-9-15

Spring has been very common in people's daily production and life, ranging from planes, trains and cars to household appliances and daily necessities, and even children's stationery for school. It can be seen how important spring is to our life.     What is the definition of spring? It is a mechanical part that uses elasticity to work. Generally made of spring steel. It is used to control the movement of mechanical parts, mitigate impact or vibration, store and measure the size of force. It is widely used in machines and instruments.     For a professional spring manufacturer, the most basic production goal is to infinitely pursue the high quality of products. Therefore, in order to improve the performance of the spring, it is often assisted by pre heat treatment, that is, the process of strengthening the quality of spring steel is used to further strengthen the spring.     In fact, the so-called pre heat treatment is what we often call annealing. It is to heat the steel to a certain temperature and keep it warm for a period of time, and then cool it slowly. Annealing of steel is a heat treatment method in which the steel is heated to the degree of phase transformation or partial phase transformation, and then cooled slowly after heat preservation. The purpose is to eliminate the structural defects of the spring, improve the structure, homogenize the composition and refine the grain, improve the mechanical properties of the steel and reduce the residual stress; At the same time, it can also reduce the hardness,...
