Description

Technical Field

[0001] The utility model relates to the technical field of metal shell plate production, in particular to a metal shell plate clamping mechanism. Background Art

[0002] Electrical metal shells refer to protective shells used on the outside of electrical equipment, usually made of metal materials. These metal shells not only provide physical protection to prevent electrical components from external impact and damage, but also act as electromagnetic shielding to reduce electromagnetic interference and radiation. The manufacturing process of electrical metal shells includes metal stamping, surface treatment and other steps. Electrical metal shells play an important role in electrical equipment, not only providing physical protection but also having electromagnetic shielding functions. They are widely used in various electrical and electronic equipment.

[0003] During the production process of metal shell plates, a clamping mechanism is required to clamp and transport the metal shell plates. However, the existing clamping mechanism is not convenient to adjust and use according to needs and cannot meet the needs of actual work.

[0004] Therefore, we propose a metal shell plate clamping mechanism to solve the above-mentioned problems. Utility Model Content

[0007] The rotation of the rotating part can drive the connecting rods at both ends to rotate, and the connecting rods can drive the clamping jaw body below to move, so that the two clamping jaw bodies move towards or in opposite directions, thereby adapting to the use of metal shell plates of different sizes.

A controller is provided on the outside of the main frame, and a servo motor 2 is fixedly installed on the top of the main bracket.

Both ends of the top of the main bracket are fixedly connected with threaded blocks, and the threaded blocks are threadedly connected to the threaded rod.

[0016] As a preferred embodiment, the output shaft of the second servo motor is arranged at the center of the rotating member, and the adjacent sides of the two clamping jaw bodies are fixedly connected with a clamping surface.

[0017] By adopting the above technical solution and setting the clamping surface, the surface of the metal shell plate can be effectively protected from being scratched.

[0018] As a preferred embodiment, two limit rods are fixedly connected to the interior of the sliding groove, and the limit rods are slidably connected to the sliding seat. The clamping surface is made of rubber, and the clamping claw body is made of high-strength steel.

[0019] By adopting the above technical solution, the clamping jaw body is made of high-strength steel material and the surface is hardened to increase wear resistance and corrosion resistance.

[0020] As a preferred implementation, the servo motor 1, the servo motor 2 and the pressure sensor are all electrically connected to the controller.

[0021] By adopting the above technical solution, the servo motor 1, the servo motor 2 and the pressure sensor can be controlled to start and stop by the controller.
