Technical Field

[0001] The utility model relates to the technical field of gear processing equipment, in particular to a gear side grinding device for gear production. Background Technique

[0002] A gear is a widely used transmission element. The side grinding of the gear is an important link in the gear processing process, mainly used to remove burrs, oxide layers, etc. generated on the gear tooth surface during the processing to improve the transmission efficiency and service life of the gear.

[0003] In the past, the side grinding of gears mainly relied on manual operation, with low efficiency and unable to meet the needs of large-scale production. Moreover, due to the inconsistency of the operation levels of workers, the grinding quality was unstable, affecting the use performance of the gears. To overcome the limitations of manual grinding, some grinding devices have appeared on the market. However, these existing grinding devices still have some defects: First, the degree of automation is low, and both loading and unloading and positioning require manual operation, restricting the improvement of production efficiency; Second, both sides of the gear need to be ground. The existing grinding devices usually can only grind one side of the gear. After finishing the grinding of one side, it is necessary for workers to turn the gear over and then grind the other side. This not only increases the labor intensity of the operating workers but also reduces the production efficiency. Therefore, it is very necessary to propose a gear side grinding device for gear production to make up for the above defects. Summary of the Utility Model

[0019] In order to make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0020] Refer to Figure 1 、The present utility model provides a gear side grinding device for gear production, which includes a frame 1. A turntable 2 is arranged on the frame 1. A driving mechanism (not shown in the figure) for driving the turntable 2 to rotate step by step is arranged inside the frame 1, which is used to drive the turntable 2 to rotate according to the set angle and speed. An upper feeding mechanism 6, a grinding mechanism 4, a turning mechanism 3 and a blanking mechanism 5 are arranged on the frame 1 in a circumferential array in sequence with the turntable 2 as the center. There are two grinding mechanisms 4, which are respectively installed on both sides of the turning mechanism 3 to facilitate grinding the two sides of the gear. A blanking groove 101 is installed on the frame 1 below the turntable 2.

[0021] Refer to Figure 2 、 Figure 3, a number of clamping mechanisms are arranged in a circumferential array on the turntable 2. The clamping mechanism includes a base 201 and a rodless cylinder 202.

A limit block 203 is arranged on one side of the base 201 adjacent to the rodless cylinder 202, and a chute 204 facing the limit block 203 is arranged on the base 201. A clamping block 7 is arranged in the chute 204. The clamping block 7 includes a telescopic block 701. The telescopic block 701 is installed in the chute 204. An arc-shaped clamping piece 704 is arranged at the top of the telescopic block 701 to cooperate with the limit block 203 to clamp the gear and prevent it from rotating during grinding. A clamping groove 703 is arranged on one side of the telescopic block 701. The clamping groove 703 is slidably connected with the slider of the rodless cylinder 202 to drive the telescopic block 701 to slide in the chute 204. A guiding groove 702 is arranged on the inner side surface of the telescopic block 701, and a guiding block cooperating with the guiding groove 702 is arranged on the inner wall of the chute 204. The guiding groove 702 is inclined, and its upper end is adjacent to the clamping groove 703. When the slider of the rodless cylinder 202 drives the clamping groove 703 to move, the cooperation between the guiding groove 702 and the guiding block enables the telescopic block 701 to move obliquely in the chute 204; when clamping the gear, the arc-shaped clamping piece 704 approaches the limit block 203 and rises to clamp the gear; before turning over or discharging, the arc-shaped clamping piece 704 moves away from the limit block 203 and descends, and its upper end is flush with or lower than the upper end of the base 201, which is convenient for the turning-over mechanism 3 and the discharging mechanism 5 to grab. In practical applications, tooth-shaped protrusions can be arranged on the surface of the arc-shaped clamping piece 704 adjacent to the limit block 203 to further improve the clamping effect and prevent the gear from rotating during grinding.

Arc surfaces are arranged on the opposite surfaces of the two claw jaws 306 to facilitate clamping the gear and rotating it for turning over. Similarly, tooth-shaped protrusions can also be arranged on the arc surfaces of the claw jaws 306 in practical applications to improve the clamping effect.

[0024] Refer to Figure 6, the blanking mechanism 5 includes a blanking support 501. A blanking cylinder 502 is provided at the top of the blanking support 501. A blanking support plate 503 is slidably provided on the blanking support 501. The blanking support plate 503 is connected to the piston rod of the blanking cylinder 502. An electromagnet 504 and an air pipe 505 are provided on the blanking support plate 503. The air pipe 505 penetrates through the electromagnet 504 and is communicated with an external air source. A blanking hole 205 is provided on the turntable 2 between two adjacent bases 201. A blanking groove 101 matched with the blanking hole 205 is provided on the frame 1. When the piston rod of the blanking cylinder 502 extends, the blanking support plate 503 slides downward. The electromagnet 504 is energized to attract the gear, and the air pipe 505 blows to purge the metal chips remaining on the base 201 due to grinding. When the turntable 2 rotates to make the blanking hole 205 face the electromagnet 504, the electromagnet 504 is de-energized and the gear drops and slides out along the blanking groove 101 to complete the blanking action.
