Description

Technical Field

[0001] The utility model relates to the technical field of scroll spring assembly, in particular to a scroll spring assembly jig. Background Art

[0002] A spring is a mechanical part that uses elasticity to work. It is usually made of spring steel. It is used to control the movement of mechanical parts, relieve shock or vibration, store energy, measure the size of force, etc. It is widely used in machines and instruments. Since there is a certain preload when the spring is installed, the force depends on the equipment and occasion. Therefore, the installation of the spring is dangerous. Therefore, some auxiliary equipment will be used when installing the spring to improve the installation efficiency while ensuring the personal safety of the operator.

[0003] There are many types of springs. According to their shapes, they are mainly spiral springs, scroll springs, leaf springs, etc. In the power distribution industry, the operating mechanism is the main part of the power distribution equipment, and the spring is an indispensable part of the operating mechanism, and the strength of the main spring is very large. The scroll spring is small in size and strong in strength, so it is more dangerous when installing the scroll spring. According to market surveys, when installing springs, most manufacturers of operating mechanisms simply fix the workpiece, and then use wire ropes to pull the scroll spring on the workpiece. This operation method is extremely dangerous and can cause casualties to operators in severe cases. Utility Model Content
