[0024] The utility model embodiment discloses a gear grinding machine for gear processing.

[0025] The utility model provides Figure 1-3 The gear grinding machine for gear processing shown includes a base 1, the upper surface of the base 1 is rotatably connected to two first rotating rods 2, the upper ends of the two first rotating rods 2 are fixedly connected to a placing table 3, and the upper surfaces of the two placing tables 3 are placed with gear bodies 4. The lower surface of the base 1 is provided with a driving mechanism, and the two first rotating rods 2 are rotated by the driving mechanism. A U-shaped plate 5 is slidably provided in the middle of the two gear bodies 4, and the inner side of the U-shaped plate 5 is rotatably connected to a second rotating rod 6, and the rod wall of the second rotating rod 6 is fixedly connected to a grinding wheel 7, and a lifting mechanism is provided above the U-shaped plate 5, and the U-shaped plate 5 moves up and down through the lifting mechanism.

[0026] The two gear bodies 4 are symmetrically fixed on the upper surfaces of the two placement tables 3, and then the U-shaped plate 5 is moved up and down between the two gear bodies 4, so that the grinding wheel 7 can grind the tooth grooves of the two gear bodies 4 at the same time to improve the grinding efficiency of the gear bodies 4.

[0027] In order to make the two gear bodies 4 rotatable, Figure 1 and Figure 3 As shown, the driving mechanism includes a first motor 8, two first bevel gears 9 and two second bevel gears 10. The first motor 8 is fixedly connected to the lower surface of the base 1. The two first bevel gears 9 are respectively fixedly sleeved on the output ends of both ends of the first motor 8. The lower ends of the two first rotating rods 2 both pass through the upper surface of the base 1. The two second bevel gears 10 are respectively fixedly sleeved on the rod wall at the lower end of the first rotating rod 2. The two first bevel gears 9 are respectively meshed with the corresponding second bevel gears 10.

[0028] Starting the first motor 8 can rotate the two first bevel gears 9, thereby rotating the two second bevel gears 10, and then driving the two first rotating rods 2 to rotate, that is, the two placement tables 3 can rotate, and then the two gear bodies 4 can rotate, so that the grinding wheel 7 can grind the remaining tooth grooves of the two gear bodies 4.

[0029] In order to make the U-shaped plate 5 move up and down, as Figure 1 As shown, the lifting mechanism includes an L-shaped plate 11 and a cylinder 12 , the L-shaped plate 11 is fixedly connected to the upper surface of the base 1 , the cylinder 12 is fixedly connected to the lower surface of the L-shaped plate 11 , and the U-shaped plate 5 is fixedly connected to the output end of the cylinder 12 .
