Grinding mechanism for automatic chain grinding machine

Abstract

The invention discloses a grinding mechanism for an automatic chain grinding machine. The grinding mechanism comprises a cam motor, a cam, a supporting shaft, a swing arm, a cutter feed position adjusting handle, an indexing supporting base, a gear shaft, a grinding wheel motor and a grinding wheel motor base. The cam motor is connected with the cam. The cutter feed position adjusting handle is mounted on the swing arm. The cam is matched with the head of the cutter feed position adjusting handle. One end of the swing arm is rotationally mounted on the supporting shaft, and the other end of the swing arm is fixedly connected with the indexing supporting base. The gear shaft is rotationally mounted on the indexing supporting base. The gear shaft is fixedly connected with the grinding wheel motor base. The grinding mechanism is further provided with a bearing, and one end of the swing arm is rotationally mounted on the supporting shaft through the bearing. Moreover, the grinding mechanism is provided with an inductive detection switch used for detecting whether the swing arm returns in place, and the inductive detection switch is matched with the swing arm. The grinding mechanism has the characteristics of being reasonable in design, simple in structure, stable in performance, high in grinding precision, easy to operate and debug and the like.

Description

Technical field [0001] The invention relates to a grinding mechanism for an automatic chain grinding machine, which is used for cyclic grinding of teeth on a saw chain and belongs to a component mechanism of the chain grinding machine. Background technique [0002] A saw chain is a cutting component on a chain saw. Its cutting edge is divided into left and right edges in the same saw chain. The saw chain is a tool used to cut objects. After long-term use, it will become less sharp, resulting in reduced cutting resistance. It is too large or even unable to cut, so it is necessary to grind the teeth of the saw chain so that it can continue to meet the needs of the work. The positioning accuracy and rigidity of the grinding mechanism directly determine the quality of the grinding amount of the saw chain teeth. In the prior art, a manual tooth grinding method is usually adopted, which has problems such as low positioning accuracy, low work efficiency, and high labor intensity. [000...

AI Technical Summary

Problems solved by technology

[0004] 1. The grinding mechanism is too complicated and the parts are not rigid enough;

[0005] 2. Many parts (especially belt drives) have cumulative assembly errors and plastic deformation, and the stability and positioning accuracy are very poor during the feeding process, which cannot meet the processing requirements;

[0006] 3. It is inconvenient to use and debug, has high requirements on the operator, and the adjustment procedure is cumbersome and complicated
