At the end of the 19th century, the principle of gear cutting and the special machine tools and tools that use this principle to cut gears appeared one after another. With the development of production, the smoothness of gear operation has received attention. Grinding machines are needed in the production process of gears to grind the upper and lower surfaces of the gears.

[0003] The currently published patent: CN 218639233 U discloses a gear grinder, which drives the sliding plate and the stabilizing rod to drive the clamping inclined rod and the clamping bracket to move inward to clamp and fix the gear by arranging an extrusion spring under the action of its own elastic force. It has a better clamping and fixing effect on the gear, can better ensure the stability of the gear clamping, and is convenient for more efficient grinding operations on the gear, effectively improving the grinding efficiency of the gear and improving people's convenience in use.

However, in the process of clamping gears of different sizes, the two clamping bevel rods only have two contact positions with the gears, and the fixing effect of the gears is not good, and the stability of the gears during the grinding process cannot be guaranteed, which affects the safety of the gears during the grinding process.
