Description
Technical Field
[0001] The utility model relates to the technical field of saw blade processing, in particular to a high-efficiency angle swinging device of a grinding head group used for saw blade processing. Background Art
[0002] The saw blade processing process involves grinding the saw blade, including grinding of specific angles such as the back angle. The device that performs the grinding process is mainly the grinding head group. Before grinding begins, the grinding head group needs to be moved to the corresponding position. The moving action is mainly an angular swing action, that is, the grinding head group is installed on the free end of a structure called a rotating seat so that it rotates around the other end of the rotating seat. For ease of understanding, this end is referred to as the rotating end here until the grinding head group rotates to a specified position, which is mainly the back angle position of the saw blade. The rotation power of the rotating seat mainly comes from the servo motor located at the rotating end. In order to avoid excessive rotation of the rotating seat, a gap is required between the rotating end and the servo motor. A worm gear reduction device is set up, which is responsible for connection and rotation at the same time, and needs to have higher precision to avoid wear as much as possible, which means that higher costs need to be invested. At the same time, the reduction device is set at the rotating end, which is particularly prone to cause the rotating seat to rotate rapidly. Therefore, the reduction ratio is better to be smaller than larger, which will cause the rotating seat to rotate too slowly, and the subsequent equipment will need to wait, so the overall efficiency is reduced. Based on this situation, how to avoid concerns about the accuracy of the reduction device as much as possible, and at the same time make the rotating seat in place on time at a suitable speed, and ultimately reduce costs and increase efficiency, is becoming an increasingly urgent problem that relevant technical personnel need to solve.
