Specific implementation mode

[0021] In order to enable the personnel in the technical field to better understand the solution of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0022] Refer to Figures 1-3 , a grinding device for processing automotive parts, including a base 1. A rotating seat 2 is fixedly installed on the top of the base 1. The rotating seat 2 is a hollow rotating platform, which is a prior art and can be driven by a motor to achieve automation. And a fixed seat 3 is fixedly installed on the top of the rotating seat 2. A through hole 4 is opened inside the fixed seat 3 for discharging the debris and cooling water generated during grinding. And an electric suction cup 5 is fixedly installed on the top of the fixed seat 3. The electric suction cup 5 is a prior art. Its working principle is to use the power generated by the motor to drive the internal mechanism, so as to form a vacuum environment inside the suction cup, and use the atmospheric pressure to firmly adsorb the object on the surface of the suction cup. The processed gear 6 can be placed on the surface of the electric suction cup 5, and the rotating seat 2 drives the gear 6 to rotate.

[0023] Refer to Figure 3 , four cooperating support plates 7 are fixedly installed on the upper surface of the base 1. A positioning cylinder 8 is fixedly installed on the inner surface of the support plate 7. The output end of the positioning cylinder 8 is fixedly connected to a top block 9 corresponding to the teeth of the gear 6. When in use, first place the gear 6 on the upper surface of the electric suction cup 5. The positioning cylinder 8 simultaneously pushes the top plate 11 to hold the gear 6, so as to quickly position the gear 6. Then use the electric suction cup 5 to adsorb and fix the gear 6. Subsequently, the top block 9 resets, and it does not affect the rotation and grinding of the gear 6. There is no need for manual operation by the operator, which improves the work efficiency.

[0024] Refer to Figure 1 , columns 10 are symmetrically and fixedly installed on the upper surface of the base 1 and outside the support plates 7. The top of the column 10 is fixedly installed with a top plate 11. A lifting cylinder 12 is fixedly installed in the middle of the top plate 11.

[0025] Refer to Figure 1 and Figure 4, the output end of the lifting cylinder 12 penetrates through the surface of the top plate 11 for sliding fit, and a mounting seat 13 is fixedly installed on its lower end surface. A water inlet pipe 14 is communicated with one side of the mounting seat 13, and a water tank 15 is communicated with the bottom of the mounting seat 13. A plurality of spray holes 16 are formed on the surface of the water tank 15, which are used to cool and reduce dust on the grinding surface when the gear 6 is being ground.

[0026] Reference Figure 4 and Figure 5 , a plurality of groups of L-shaped plates 18 are slidably installed on the upper and lower surfaces of the water tank 15. A rotating shaft 23 is rotatably installed on the opposite surfaces of a group of L-shaped plates 18. A grinding roller 24 is fixedly installed on the surface of the rotating shaft 23. The grinding roller 24 faces one group of spray holes 16, so that the spray holes 16 can cool the grinding roller 24 while cooling the gear 6, improving the service life and grinding effect of the grinding roller 24. A motor 22 for driving the rotating shaft 23 is fixedly installed on the upper surface of the L-shaped plate 18. During use, the motor 22 drives the grinding roller 24 to rotate, thereby grinding the inner ring of the rotating gear 6.

[0027] Reference Figure 5 , fixing blocks 17 are fixedly installed on the upper and lower surfaces of the water tank 15 on one side of the L-shaped plate 18. An electric telescopic rod 19 is fixedly installed between the fixing block 17 and the L-shaped plate 18. The output end of the electric telescopic rod 19 pushes the L-shaped plate to slide. During use, the electric telescopic rod 19 pushes the L-shaped plate 18 forward, so that the grinding roller 24 is always in contact with the inner ring of the gear 6, improving the grinding effect and also being able to adapt to the grinding of the inner surface of gears 6 within a certain size range.

[0028] Reference Figure 4 , a plurality of scraping plates 25 corresponding to the inner ring of the gear 6 are fixedly installed on the outer surface of the water tank 15 to scrape off the residual debris on the inner ring of the gear 6, further enhancing the grinding effect. The scraping plate 25 is made of rubber material, so that the scraping plate 25 is always in contact with the inner ring of the gear 6, further enhancing the cleaning effect. A scraping groove 26 is formed inside the scraping plate 25, so that the upper and lower ends of the scraping plate 25 are in contact with the upper and lower surfaces of the gear 6, removing the debris splashed on the end face of the gear 6 more thoroughly, reducing the trouble of subsequent processing. During use, the scraping groove 26 is stuck on the upper and lower end faces of the gear 6, and the debris and cooling water generated by the grinding of the inner ring of the gear 6 during rotation are scraped off.

[0029] Further, compress the grinding roller 24 so that the grinding roller 24 penetrates through the inner ring of the gear 6. The electric telescopic rod 19 pushes the grinding roller 24 to always be in contact with the inner ring of the gear 6. The rotating seat 2 drives the gear 6 to rotate in the opposite direction of the scraping plate 25, and then the motor 22 drives the grinding roller 24 to rotate, so that the grinding roller 24 grinds the inside of the gear 6. At the same time, the spray holes 16 spray and cool the grinding roller 24 and the gear 6. Secondly, the scraping plate 25 scrapes off the debris and cooling water generated by the grinding of the inner ring of the gear 6.
