A sleeve type spindle rotation device and processing equipment

Abstract

The invention discloses a sleeve-type main shaft rotating device, which comprises a rotating part and a supporting part. The rotating part includes a main shaft (1), and the two ends of the main shaft (1) are fixedly installed on the supporting part. The rotating part also includes a sleeve. (2), the sleeve (2) is installed on the main shaft (1) through rolling parts (3), the grinding wheel (4) is fixed on the sleeve (2), and the main shaft rotation device further includes a pulley for transmitting torque (5), the belt pulley (5) is sleeved on the main shaft (1) and is fixedly connected with the sleeve (2). The present invention also proposes a processing device, which includes a device body (11) and the above-mentioned main shaft turning device, and the main shaft turning device is fixed on the device body (9).

Description

technical field [0001] The invention relates to the technical field of processing equipment, in particular to a sleeve-type spindle turning device and processing equipment. Background technique [0002] In the printer rubber roller processing industry, ordinary cylindrical grinders are usually used for grinding workpieces. In ordinary cylindrical grinder parts, the width of the grinding wheel is 30-50mm, while the surface processing length of the rubber roller of the printer is greater than 250mm, that is, the width of the grinding wheel is smaller than the width of the processing surface of the workpiece. Therefore, the grinding wheel needs to be reciprocated during the processing to adapt to the workpiece. Machined surface. The above-mentioned operation and processing methods have the following disadvantages: the reciprocating action of the grinding wheel makes the operation and processing efficiency low; the feed force of the reciprocating action of the grinding wheel on...

AI Technical Summary

Problems solved by technology

The above-mentioned ordinary spindle turning device has a complex design structure, a large overall weight, and high requirements for the size and installation accuracy of the parts.

If the size of the parts installed at both ends of the main shaft is difficult to maintain consistency, and the installation and positioning accuracy cannot be guaranteed, the movement of the main shaft will not be smooth when the main shaft rotates, and the bearings will easily heat up, which will affect the rotation accuracy of the wide grinding wheel installed on the main shaft, making the rubber roller of the printer It is difficult to guarantee the processing accuracy, which reduces the quality of the printer's rubber roller
