Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of motor iron core clamps, and more specifically, to a turning clamp for a motor stator iron core with windings. Background Art
[0002] The stator core with windings often needs to be lifted and flipped at an angle. When lifting it with the current clamp, workers usually need to clamp the motor core with a wrench. When workers use the wrench to clamp the motor core, it is difficult to control the size of the clamping force. When the clamping force is too large, it is easy to cause scratches and deformation on the surface of the motor core. When the clamping force is insufficient, the core is easy to slip to the ground during the flipping process, resulting in scrapping and even possible injury to the operator. At the same time, after the current clamp clamps the core, it is necessary to manually flip the core, which is very laborious.

[0020] When the motor 9 is turned on the cam 13, the support rod 13 is rotated to move relative to the outer surface of the motor core, thereby reducing the risk of the motor core falling off and the like.
[0021] like Figure 1 and 2 As shown, a mounting clip 2 is provided in the middle of the upper end of the clamp hanger 1, and a through hole is provided in the middle of the mounting clip 2. The mounting clip 2 facilitates the connection of an external lifting mechanism with the clamp hanger 1, and facilitates the lifting and movement of the clamp hanger 1.
[0022] like Figure 4 As shown, an anti-slip support pad 18 is provided on the side of the core splint 17 away from the second rotating connecting block 15, and the core splint 17 and the anti-slip support pad 18 are both in the shape of an arc plate.

At the same time, the support spring 16 will support the outer end of the core splint The surface, that is, the elastic pressure exerted by the support spring 16 on the core clamp makes the core clamp maintain a state of being close to the outer end face of the motor core, effectively increasing the stability of the core clamping of the motor core by the core clamp, and avoiding the motor core from falling when the motor core is tilted at an angle; further, the anti-slip support pad 18 is used to increase the friction with the outer end face of the motor core during the clamping process, thereby further ensuring the stability of the motor core clamping; then the staff will control the adjustment motor 9 to work, and the adjustment motor 9 will drive the first gear 11 to rotate. When the first gear 11 and the second gear 12 are in meshing state, it will drive the support slide bar 13 to rotate, thereby rotating the clamped motor core at different angles, saving manpower.
