[0028] In mechanical production, workpieces need to be fine-machined to meet the accuracy requirements of tool use. Grinding is an important process in mechanical processing. Grinding the outer circle is a necessary process for all shaft processing parts. The various existing required shaft parts generally need to be polished on their outer surfaces.

[0029] In the related technology, there is a mechanical processing cylindrical grinder that can clamp and fix circular workpieces of different sizes in the front, back, left and right directions, so that the fixing effect is better, while ensuring that the workpiece is more evenly stressed, avoiding deformation, and facilitating the adjustment of the grinding mechanism. However, it also has certain defects. The fixing method of this scheme is still to fix the end and grind the other end. After the grinding of the other end is completed, the end is turned around for grinding, which greatly affects the grinding processing rate. Secondly, when the device is used to grind an overly long shaft, the middle area may not be able to be ground, and there are certain limitations.

[0030] In order to solve the problems in the related technology to a certain extent, the embodiment of the present application provides an external cylindrical processing grinder. When in use, the shaft part whose external cylindrical surface needs to be polished only needs to be placed vertically on the base 1, and then clamped and fixed by the threaded rod 1 21, and then the threaded rod 2 35 is adjusted so that the grinding disc 36 is close to the shaft part to be processed, and then the motor 37 is started, and the grinding disc 36 is driven to rotate through the transmission wheel group 33 for grinding. The entire grinding component of the device is arranged on the linear module 31. During grinding, the grinding disc 36 not only rotates, but also moves up and down driven by the linear module 31, so as to realize the grinding of the entire shaft part, which greatly increases its convenience and practicality.

[0031] The present application is described below with reference to the accompanying drawings and specific embodiments:
