[0003] The Chinese utility model patent with the patent number 2022216576694 discloses a gear workpiece processing and grinding device, including: a mounting frame located on one side of the gear to be processed. The mounting frame is in a "C" shape and is inclined; a guide plate parallel to the mounting frame and fixed inside the mounting frame. A grinding block is slidably connected to the lower surface of the guide plate. Both side surfaces of the grinding block are inclined, and the surface of the grinding block fits the edge of the tooth groove of the gear to be processed. Generally, before each grinding of the gear, it is necessary to manually fix the gear on the base, and after the gear is ground, it needs to be manually disassembled, and then manually replace the next gear for grinding. The operation is relatively cumbersome and requires a special operator to watch, resulting in low production efficiency. Content of the Utility Model

[0025] At the same time, the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0026] Working principle of the utility model: When the device is working, first place the gears to be polished on multiple connecting columns 23, and do not place a gear on one of the connecting columns 23, which is used to place the polished gears. Then control the first motor 21 to drive the turntable 22 to rotate slowly, so that one of the connecting columns 23 with the gear to be polished is concentric with the rotating shaft 32. Then control the mounting table 1 to slide towards the mounting table 2, so that the end faces of the connecting column 23 and the rotating shaft 32 are aligned. Then control the U-shaped flap 55 at one end of the guide plate 54 of the mounting table 3 to dial the gear at the front of the connecting column 23 onto the rotating shaft 32. Then retract the mounting table 1. Then control the first motor 21 to drive the turntable 22 to rotate slowly so that the cylindrical column 2 is concentric with the rotating shaft 32. Then control the mounting table 1 to slide towards the mounting table 2. Since the diameter of the cavity of the cylindrical column 26 is the same as the diameter of the rotating shaft 32, the cylindrical column 26 just fits over the outer surface of the rotating shaft 32 and can firmly fix the gear to be polished. Then control the grinding wheel 44 on the column 4 to grind the tooth surface of the gear. During the grinding process, the second motor 35 slowly drives the rotating shaft 32 to rotate, so that the grinding wheel 44 can grind each tooth surface of the gear. When a gear is polished, control the mounting table 1 to slide outwards so that the cylindrical column 26 is separated from the rotating shaft 32. Then control the turntable 22 to rotate so that one of the connecting columns 23 without a gear is concentric with the rotating shaft 32, and control the mounting table 1 to slide so that it is aligned with the rotating shaft 32. Control the U-shaped flap 55 at one end of the guide plate 54 to dial the gear onto this connecting column 23. Since the gear fits tightly with the rotating shaft 32 during the processing, the electric hydraulic rod 38 can be controlled to push out the gear. Then repeat the above operations to grind the next gear. Compared with the prior art, the utility model can place multiple gears on the connecting columns 23 of the turntable 22 and grind them, and there is no need for manual intervention, and the gears are completely automatically replaced and ground by the machine.
