Abstract

The invention provides a polishing machine and a main shaft takeup thereof. The main shaft takeup comprises a fixing part and a movable part, wherein the fixing part is fixedly arranged out of a main shaft of the polishing machine; the movable part is movably arranged relatively to the fixing part; the movable part comprises a contact part and a terminal; the contact part can be moved to the first position or the second position relatively to the fixing part; on the first position, the terminal of the movable part extends into the groove of the main shaft to clamp the main shaft; and on the second position, a preset distance is left between the terminal of the movable part and the main shaft to loosen the main shaft. In the main shaft takeup, the movable part has two different positions relatively to the fixing part; on the first position, a polishing wheel can be replaced; and on the second position, the polishing operation can be successfully carried out. Compared with the prior art, the main shaft takeup has the advantages of high working efficiency, stable performance, small influence on main shaft precision and the like.

Description

technical field [0001] The invention relates to the field of machine tools, in particular to a polishing machine main shaft tensioning device and a polishing machine comprising the main shaft tensioning device. Background technique [0002] my country is a country with a large demand for machine tools, and it needs to import a large number of machine tools from abroad every year, especially large and heavy machine tools. In recent years, the domestic demand for polishing machines has gradually increased. The polishing machine uses the high-speed rotation of the polishing wheel to polish the surface of the workpiece to improve the surface finish of the workpiece. [0003] After the polishing machine has been used for a certain period of time, the polishing wheel is severely worn and needs to be replaced. During the replacement process of the existing polishing machine, since there is no fastening device on the main shaft, when the polishing wheel is unloaded, the main shaft...
