Description

Technical Field

[0001] The utility model relates to a riveting device for a moving contact. Background Art

[0002] Dynamic touch bridge, such as Figure 10 As shown, it includes a moving contact bridge arc-shaped raised portion 60, and both ends of the moving contact bridge arc-shaped raised portion 60 are bent outward in sequence to form a moving contact bridge contact portion 62. The moving contact bridge contact portion 62 is provided with a moving contact bridge rivet hole 63 for riveting with the moving contact bridge. A first arc-shaped bottom 61 of the moving contact bridge and a second arc-shaped bottom 64 of the contact bridge are formed between the moving contact bridge arc-shaped raised portion 60 and the moving contact bridge contact portion 62. In order to improve the riveting of the moving contact bridge and the moving contact point, the riveting speed and quality are greatly improved, and it is suitable for large-scale riveting production. The riveting is carried out by a rotary table automatic riveting method. However, in the actual riveting process, it was found that the moving contact bridge receiving fixture used for transfer to each workstation had errors in size due to its fixed structure, resulting in the moving contact bridge being placed on the moving contact bridge receiving fixture by the robot. It is easy for the moving contact bridge to not be placed in or to be placed too loosely. The problem of empty rivets affects the riveting efficiency and is also easy to cause damage to the moving contact bridge receiving fixture. On the other hand, placing it too loosely will lead to inaccurate positioning when riveting the moving contact, resulting in the risk of crooked riveting and a high riveting error rate. To address this problem, the existing moving contact riveting device is improved and optimized. Utility Model Content
