Fine adjustment worm device for grinding machine

Abstract

The invention discloses a fine adjustment worm device for a grinding machine. The side wall of one end of a worm shaft is provided with a worm gear; the periphery of the middle section of the worm shaft is sleeved with a shaft sleeve, the shaft sleeve supports the worm shaft through a first bearing part and a second bearing part, and the side wall of the shaft sleeve is fixed on the grinding machine through a bolt; a dial and a hand wheel are fixed at the end, far away from the worm gear, of the worm shaft, and the hand wheel, the dial and the worm shaft are in linkage through a flat key. According to the fine adjustment worm device for the grinding machine, the operation steps are simplified, damage is not prone to occurring in use, the flexibility, stability and accuracy are good in the operation process, and therefore the accuracy of a processed grinding piece finished-product is higher.

Description

technical field [0001] The invention relates to the field of machining, in particular to a fine-tuning worm device for a grinding machine. Background technique [0002] In the processing of mechanical parts, grinding is an important processing step to ensure the processing accuracy of parts. A grinding machine is a machine tool that uses abrasive tools to grind the surface of a workpiece, and it is widely used. In grinding machine equipment, worm drive has the characteristics of compact structure, large transmission ratio, large transmission power range, stable operation, and self-locking, etc., and is widely used. However, the conventional worm system in the grinding machine adopts the method of separate adjustment of the worm and the worm frame. This structure is complex, the worm is easily damaged during use, and the flexibility, stability and accuracy are poor. Therefore, how to manufacture a worm device that is easy to operate, flexible, stable and accurate in the mov...
