The obvious disadvantage of this processing method is the same as that of the first processing method. The X-axis feed is realized by the ball screw driven by the servo motor. The X-axis feed is extremely small, and the rotation speed of the AC servo motor is very low. Vibration occurs, causing the grinding head to crawl. In addition, the feed speed of the grinding head is too low, and the rigidity of the ball screw transmission is poor, which will also cause low-speed crawling. It is difficult to ensure the machining accuracy and surface roughness of the workpiece.
And in the process of processing, it needs repeated local grinding before it can be used reluctantly, the processing efficiency is low, and there are slight knife marks on the surface, and the surface accuracy is also very bad.

The invention discloses a micro-feed device for grinding of convex or dished shafts on a turning and grinding machine, which comprises an eccentric shaft, a transmission chain and a drive device. The eccentric shaft serves as an output component of the micro-feed device, the transmission chain at least comprises a reduction mechanism, an output end of the transmission chain is connected with the eccentric shaft to drive the eccentric shaft to rotate around a rotary shaft of the eccentric shaft, and the drive device is connected with an input end of the transmission chain. By means of the micro-feed device for grinding of convex or dished shafts on the turning and grinding machine, precision in machining of convex or dished parts can be guaranteed effectively.
Description
technical field [0001] In the process of grinding shafts with convex or concave curved surfaces on a lathe, it is necessary to control the micro-feed smoothly in the radial direction to complete the precision grinding of shaft parts with convex or concave curved surfaces. The present invention relates to a method for such processing A device for radial micro-feeding. Background technique [0002] At present, there are two methods available for processing convex or concave shaft parts. [0003] The first processing method is the processing realized by the CNC lathe as the processing equipment. In this processing method, the precision processing of the convex or concave shaft parts first adopts the CNC lathe to realize X and Z axis interpolation through programming, and the surface of the workpiece Rough machining and molding, and then polishing methods such as abrasive belts and cloth wheels to improve the surface roughness. [0004] The obvious disadvantage of the above-me...
