Abstract

The invention relates to the technical field of hollow shaft machining, in particular to a hollow shaft inner wall polishing and painting device. The device comprises a base; the base is fixedly connected with an extension block capable of vertically extending, a shaft sleeve contacted with the extension block and a support table in sequence; a hollow shaft to be machined is arranged in the shaftsleeve; a lead screw is arranged in the hollow shaft; a motor is arranged on the support table; the lead screw is rotationally connected with a painting disc in clearance fit with the hollow shaft, ascraper butting against the inner wall of the hollow shaft and a clamping jaw detachably connected with the motor in sequence; the painting disc and the scraper are both disc-shaped; the painting discis fixedly connected to the scraper through a connecting rod; the scraper is fixedly connected with the hollow shaft through a connecting rod; the painting disc is provided with holes for spraying out paint; the clamping jaw comprises a clamping jaw foot and a fixed block; the clamping jaw foot is elastically connected with the fixed block; and a groove is formed in the end part of the clamping jaw foot. The device can realize polishing and painting of the inner wall of the hollow shaft.

Description

technical field [0001] The invention relates to the technical field of hollow shaft processing, in particular to a hollow shaft inner wall grinding and painting device. Background technique [0002] Hollow shafts are often required to be machined in machining. The side wall (inner side wall and outer side wall) of the hollow shaft made of rolled plate is irregular. When processing the hollow shaft, a large lathe and special fixture are generally used to process the end face and side wall of the hollow shaft. The special fixture cooperates with the large lathe to ensure the hollow shaft. Axis machining accuracy. However, for small factories that undertake small batches of products, the processing cost of hollow shafts with large lathes and special fixtures is relatively high, which increases input costs and is not conducive to the production and manufacturing of small factories. [0003] In order to solve the above problems, the Chinese patent with the notification number C...
