Description

Technical Field

[0001] This utility model relates to the field of hub motor technology, specifically to a processing and fixing device for hub motor mounting surfaces. Background Technology

[0002] The accumulated error of components such as the disc brake end cap of the hub motor after assembly is relatively large. Therefore, before assembling the disc brake disc, the disc brake disc mounting surface of the disc brake end cap needs to be machined. Previously, when machining the disc brake pads, they needed to be clamped and fixed to facilitate subsequent processing. However, the old-style fixing and positioning devices would cut away the machined area of ​​the disc brake pads during the clamping process, thus hindering subsequent machining. Furthermore, the position needed to be adjusted during machining, which was very inconvenient. In the existing technology, to solve the problems mentioned in the background art, [the technology has been addressed]. Various types of disc brake processing and fixing devices have been developed. For example, patent document CN216577449U discloses a disc brake processing device that facilitates fixing, and patent document CN211841684U discloses a clamping device used in disc brake disc production. Although the above clamping devices achieve clamping operations, they cannot effectively guarantee the exposure and processable area of ​​the disc brake disc during processing, and the clamping strength is uncontrollable. Based on this, this utility model designs a processing and fixing device for the hub motor mounting surface to solve the above problems. Utility Model Content
