Adjustable mechanical arms are commonly used in offices, laboratories, studios and other locations to support objects at various angles and heights, such as lights, computer screens, laboratory instruments, microphones, etc.
The adjustable manipulator consists of a base member and two connecting rods connected through a pivot joint, which are held in place by friction in the joint. By using spring assisted balancing devices that compensate for most of the weight, the amount of friction required to keep the equipment in place is reduced.
The pivot is a connecting ring that can rotate around an axis set at the pivot point, and a way to attach a spring to the pivot point to reduce the amount of force required. Apply to the arm to place the supported object in the desired position. The auxiliary balance device uses a constant force spring, because the constant force spring provides a smooth range of motion and a constant load in the extension or retraction direction. This can provide smooth motion and force requirements that predict the smallest detail, and the force applied by the constant force spring is more constant over the entire range of motion of the two arms of the device.
If coil spring balance is used, a constant force may not be applied to the supported object at all positions of the upper arm part and the lower arm part. For example, at the far end of the range of motion, usually, the force applied to the supported object is insufficient or too large, making it difficult and troublesome to place the object at the extreme position of the range of motion. The range of motion of any part of the arm. Mechanical components have a great impact on the quality and safety of applied products. Therefore, it is suggested that when looking for spring manufacturers, you should choose manufacturers with rich production experience to integrate spring components into your design.
