Description

Technical Field

[0001] The utility model belongs to the technical field of drive components and relates to a drive component of a special clamp for welding a clamp housing. Background Art

[0002] There are generally two existing automobile welding clamping methods: one is to use an eccentric clamping cylinder, but due to the limited clamping output torque of the eccentric clamping cylinder, self-locking cannot be achieved. The other is to purchase an integrated clamping cylinder. Regardless of the clamping method, the important carrier of the welding clamp is the shell structure, and a special clamp is required to achieve clamping processing.

[0003] In order to ensure the clamping force and improve the clamping stability, a driving component is required. The common driving structure uses a cylinder to drive the clamp to move, and points are arranged at multiple angles to achieve comprehensive clamping operations. However, the disadvantage of this approach is that there is only a single driving method and it is impossible to drive in multiple directions. For this reason, we designed a driving component for a special fixture for welding the clamp housing. Summary of the invention
