Description

Technical Field

[0001] The utility model belongs to the technical field of motor component processing, and in particular relates to a pressure ring anti-warping device. Background Art

[0002] At present, in the processing of some motor bases and end caps, the workpiece needs to be pressed and fixed. A motor base 10 in the prior art has a plurality of ear tabs 11 at its top, which serve as pressing points.

[0003] When a hydraulic or pneumatic pressing mechanism is used for pressing, the number of lugs 11 on the workpiece is inconsistent. In order to improve the versatility of the pressing mechanism, a pressing ring needs to be added to the lug 11. In this way, no matter whether the number of lugs 11 on the workpiece is odd or even, the pressing plate of the pressing mechanism can press the workpiece through the pressing ring.

[0004] The clamping mechanism includes multiple pressure plates 13 corresponding to the ear strap 11. The speed of the multiple pressure plates 13 when pressing the pressure ring may be asynchronous, which may cause one side of the pressure ring on the ear strap 11 to tilt up, affecting the clamping action of the rear pressure plate 13, and even causing a situation where the pressure cannot be tightened.
