[0002] Gears refer to mechanical components with gears on the wheel rim that continuously mesh to transmit motion and power. The application of gears in transmission has appeared very early. With the development of production, the smoothness of gear operation has received attention. Gear processing is a process that uses mechanical methods to obtain the specific structure and precision of gears. Gears are the core transmission components in automotive sports. In the gear processing technology, it is usually necessary to grind the end faces of the gears.

[0003] For example, the Chinese patent with publication number CN213765143U proposes a gear end face grinding device for gear processing. The patent sets a movable plate and a gear rack. Six gear racks are set on the movable plate. Before starting the machine, the gears are placed on the gear racks. At the same time, the servo motor is started to drive the screw to move, so that the first gear rack on the right side moves to the bottom of the grinding mechanism, and the hydraulic cylinder pushes the grinding mechanism to grind the gears. After grinding, the gear rack continues to move to the second gear rack on the right side and moves to the bottom of the grinding mechanism for grinding. At the same time, the gears on the first gear rack on the right side are removed and new ones are placed. Based on this, the gear rack can move left and right in the processing groove, and the gears can be taken and placed while processing, saving time for taking and placing the gears.

[0004] However, the above scheme still has the following disadvantages:

[0005] During gear processing, the gear is placed on a gear rack for processing. Since there is no limiting structure to restrict the gear, the gear is likely to move during processing, thereby affecting the grinding effect of the gear end face. Utility Model Content
