Problems solved by technology

The shaft sleeve workpiece is the main type of shaft-type workpiece. The shaft sleeve is a cylindrical mechanical part that is sleeved on the rotating shaft. It is an integral part of the sliding bearing. During the production and processing of the shaft sleeve mechanical workpiece, the shaft sleeve workpiece It needs to go through the processing steps of die-casting, grinding and drilling in sequence. The shaft sleeve workpiece has various types of sizes, specifications and appearance shapes, especially when grooving the inner arc surface of the shaft sleeve with a hemispherical structure. Some processing equipment is difficult to meet the needs of shaft sleeve processing. Because the end of the shaft sleeve is a circular structure, the existing clamping mechanism is difficult to fasten and fix the shaft sleeve conveniently and efficiently. The clamping and fixing of the shaft sleeve causes the shaft sleeve to fall off, and the existing clamping mechanism is difficult to apply to the clamping and fixing of shaft sleeve workpieces of various sizes and specifications, and the scope of application is narrow. Among them, the shaft sleeve is clamped and fixed, and the processing head is adjusted according to the needs, so as to realize the processing of the shaft sleeve. However, due to the complex structure of the processing head and many driving mechanisms, it is difficult for the processing head to The shaft sleeve processing requires convenient and smooth operations such as rotation and translation. It is difficult for the existing shaft sleeve processing mechanism to achieve a stable and accurate rotation and adjustment position after the shaft sleeve is clamped and fixed. Therefore, in the processing process of the existing shaft sleeve workpiece Among them, the processing process is extremely cumbersome, and the processing cycle is also long, which cannot meet the large-scale production and processing of shaft sleeve workpieces. The existing grooving processing mechanism has complex structure and troublesome operation, and it is difficult to perform grooving processing on the arc surface smoothly. The adjustment of the processing cutter head is troublesome. It is difficult to quickly and conveniently adjust the processing cutter head along the inner arc surface of the shaft sleeve, and the adjustment accuracy is poor. Groove processing cannot meet the needs of workpiece processing
