Description

Technical Field

[0001] The utility model relates to the technical field of motor shell processing, and more specifically, to a motor shell processing clamping device. Background Art

[0002] In the motor manufacturing industry, motor housing factories mainly use cast iron and cast aluminum, and make motor housings by casting. During the motor housing processing, it is necessary to ensure the concentricity and parallelism of the iron core in the middle of the motor housing and the stoppers at both ends. The inner hole of the motor housing and the stoppers at both ends need to be turned flat by turning equipment, so a fixing device for clamping the motor housing is needed.

[0003] The Chinese patent application number CN202121897321.8 discloses a fixing device for the production and processing of motor housings, including a support platform, a swivel movably connected to the middle of the support platform, and a clearance groove on the surface of the swivel. The utility model can realize the rotation of the ball screw driven by the bottom plate through the gear ring 1 by the engagement of the gear ring 1 and the gear 1. The three ball screws are respectively engaged with the three moving blocks, and the three moving blocks can respectively drive the three support blocks to move toward the end away from the center of the support platform, so that the three support blocks fit with the inner wall of the motor housing, thereby fixing the motor housing. By moving the three support blocks to different distances, different motor housings can be fixed, which increases the scope of use of the device.

[0004] However, it can be seen from the drawings in its specification that when the motor casing is fixed by side clamping, it is easy to cause the casing to deform due to external force problems when the thickness is relatively thin, and ultimately lead to excessive deformation of the finished product after processing, affecting the internal concentricity, resulting in serious out-of-tolerance phenomenon, and affecting the concentricity quality of the motor after assembly. Therefore, a motor casing processing clamping device is proposed. Utility Model Content
