Description

Technical Field

[0001] This application relates to the field of tooling and fixture technology, and in particular to a tooling and fixture for automatic pressing of mouse scroll wheels. Background Technology

[0002] refer to Figure 1 The roller includes an outer ring 40, a locking ring 42, and an inner ring 41. The inner ring 41 is located inside the outer ring 40, and the locking ring 42 is located between the outer ring 40 and the inner ring 41. The locking ring 42 can lock the inner ring 41 inside the outer ring 40. During the assembly process, the inner ring 41 needs to be placed inside the outer ring 40 first, and then one end of the locking ring 42 is inserted between the outer ring 40 and the inner ring 41, thereby installing the inner ring 41 inside the outer ring 40. The roller can be installed through the above assembly steps. However, since the locking ring 42 and the outer ring 40 are connected by a snap, a large amount of force is required to install the locking ring 42 inside the outer ring 40 during assembly. Subsequently, under long-term operation, it will reduce the work efficiency of the workers. Utility Model Content

Then, the outer ring, inner ring, and locking ring are placed into the placement slots on the transport side of the first, second, and third feeding components, respectively. Next, the moving cylinder pulls the lower template in the opposite direction, moving it below the upper template. Then, the pushing cylinder is activated to drive the upper and lower templates closer together. Subsequently, the top block at the lower end of the upper template abuts against the upper end face of the locking ring, thereby installing the locking ring between the outer and inner rings. Then, the pushing cylinder lifts the upper template, moving it away from the lower template. After that, the assembled roller can be removed from the placement slot, improving the efficiency of roller assembly. Attached Figure Description
