Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of rotating shaft processing, and particularly relates to a motor rotating shaft grinding device capable of adapting to rotating shafts of multiple specifications. BACKGROUND

[0002] Rotating shaft processing grinding is a key final working procedure in precise rotating shaft manufacturing, which uses a high-speed rotating grinding wheel to perform micro cutting on a rotating shaft after primary processing such as turning. The core purpose of this process is to extremely improve the dimensional accuracy, geometric shape accuracy and surface finish of the rotating shaft, and to eliminate micro defects left by the previous working procedure. Through accurate grinding, not only can the rotating shaft and accessories such as bearings and gears achieve optimal cooperation and low-friction rotation, but also the rotation accuracy, dynamic balance, wear resistance, service life and operation stability of the whole machine can be significantly improved. When the existing rotating shaft grinding device is used, two clamping plates are usually arranged at one end of the rotating shaft, and the two clamping plates are close to each other to clamp and fix one end of the rotating shaft. At this time, the two clamping plates drive the rotating shaft to rotate at a constant speed, and the grinding wheel moves back and forth above the rotating shaft, thereby completing the grinding work of the rotating shaft. Since the rotating shaft needs to be clamped by a clamp during grinding and driven to rotate at a constant speed, in order to avoid tool collision, the rotating shaft needs to be staggered from the clamping position of the clamp when the grinding wheel moves back and forth, so that there is a dead angle in the grinding of the rotating shaft. After single grinding, the clamping plates need to be loosened, the rotating shaft needs to be turned and then inserted between the two clamping plates again, and clamped, so as to complete the overall grinding of the rotating shaft. The back-and-forth clamping and turning reduce the work efficiency of the rotating shaft grinding. SUMMARY

[0003] The purpose of the present application is to solve the problem in the prior art that the clamping direction of the rotating shaft body needs to be changed during processing to avoid dead angles, thereby reducing work efficiency, and to provide a motor rotating shaft grinding device capable of adapting to rotating shafts of multiple specifications.
