With the development of production, the stability of gear operation has been paid attention to. The burrs on the rear end face of the gear production will affect the stability of the gear, so it is necessary to grind and smooth the two end faces; for example, the Chinese invention patent with the authorization announcement number CN220993855U discloses a gear end face grinding device, which discloses a workbench, the upper end face of the workbench is provided with a fixing component for fixing the gear, the side of the workbench is provided with a lifting component, and the lifting component is connected to a grinding component for grinding the gear end face; the fixing component includes a placement frame arranged on the end face of the workbench, a positioning column is arranged at the center of the placement frame, and the inner wall of the placement frame is provided with a plurality of hydraulic rods facing the center thereof, and the hydraulic rod is provided with a clamping block for cooperating with the outer teeth of the gear, but the current gear end face grinding has the following defects:

[0050] Embodiment 3:

[0051] See also Figure 1-14, which is the second embodiment of the present invention. This embodiment is based on the previous embodiment. When the present invention is used, six gear workpieces are sleeved on the short sleeve shaft 292 on the station assembly 29. After the conveying table 13 moves to the position of the grinding structure 4, the cylinder 317 in the driving structure 3 lifts the position of the gear box 31, so that the spline head 315 is inserted into the spline groove 211 of the furniture structure 2 at this position, and the second positioning block 320 is inserted into the positioning port 18 of the conveying table 13 at this position. At the same time, the grinding disc 44 in the grinding structure 4 is pressed down to contact the end faces of the six gear workpieces. After that, the first servo reduction motor 314 is started, driving the gear workpiece to rotate and revolve, generating friction with the grinding disc 44 for grinding. In this process, the second pneumatic push rod 313 will change the position of the first ball spline 37 for many times, and constantly change the movement speed of the gear workpiece. After the grinding is completed, the cylinder 317 lowers the position of the gear box 31, and the conveyor table 13 moves to the flip structure 5. At this time, the first pneumatic push rod 115 drives the first positioning block 114 to move up and insert it into the positioning port 18 of the conveyor table 13 at this position. The flip structure 5 is operated by two soft The clamping block 515 clamps both sides of the gear workpiece, lifts the gear workpiece away from the short sleeve shaft 292, then rotates the gear workpiece 180 degrees and puts it back to the short sleeve shaft 292, completing the turning over of the six gear workpieces in sequence, and then the conveying platform 13 is conveyed to the position of the grinding structure 4 again to grind the other end face, completing the grinding work of the two end faces of the gear workpiece; the present invention can fix the inner hole of the gear workpiece on the short sleeve shaft 292, and set six workstation assemblies 29, which can fix six gears at the same time, and can grind six gears in batches at one time. The gear is fixed by inserting the short sleeve shaft 292 into the inner hole. The gear can be fixed under the pressure of the grinding disc 44 and the supporting force of the round table 291 during grinding. No clamping is required, which is more convenient. When grinding, the workstation assembly 29 will carry the gear workpiece to rotate on its own and also revolve around the center of the turntable 23. The friction direction generated by the grinding disc 44 is more diverse, and the speed is continuously changed to drive the movement of the gear workpiece, which complicates the movement of the gear workpiece and improves the quality of grinding.
