An armature iron core polishing device for electric tools

Abstract

The invention discloses an armature iron core polishing device for electric tools, which relates to the field of armature iron core polishing devices. The polishing component for armature iron core polishing, this device can achieve the effect of elastically grinding the armature iron core. It only needs to clamp and fix the armature iron core on the side distributed along the length of the transmission rod, and then the polishing and polishing plate can be used. Polish the surface of the armature iron core to a fixed thickness. When there are protrusions on the surface of the armature iron core that are difficult to polish, the polishing plate will be conflicted by the protrusions on the armature iron core and compress the first spring to avoid it. The protruding position is slowly polished away, and the phenomenon that the protuberance is polished off at one time will not form a difficult-to-repair depression on the surface of the armature iron core.

Description

technical field [0001] The invention relates to the field of armature iron core polishing devices, in particular to an armature iron core polishing device for electric tools. Background technique [0002] The armature is a key and pivotal component in the process of realizing the mutual conversion of mechanical energy and electrical energy. For generators, it is the component that generates electromotive force, such as the rotor in DC generators, and the stator in AC generators; for motors, it is the component that generates electromagnetic force, such as the rotor in DC motors. [0003] In the prior art, the armature iron core is usually polished with a hard polishing tool, such as a hard grinding brush. Maintain a fixed distance between the armature and the armature during polishing, so that when the armature surface is in a difficult-to-polish position, it is easy to cause serious wear and damage to the polishing tool, reducing the service life of the polishing tool, and...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, the armature iron core is usually polished with a hard polishing tool, such as a hard grinding brush. It is difficult to control the polishing accuracy during polishing, and because the hard polishing tool is hard on the armature. Keep a fixed distance between the armature and the armature during polishing, so that when the surface of the armature is difficult to polish, it is easy to cause serious wear and damage to the polishing tool, reducing the service life of the polishing tool, and if there is a small bump on the surface of the armature When lifting, if the grinding tool is directly polished or scraped at one time, the surface of the armature is likely to be dug out to form a concave state when a small piece of protrusion falls off. When the surface of the armature forms a depression, it is not easy to repair, and it is usually discarded. , reducing the polishing yield
