[0024] To make the objectives, technical solutions, and advantages of the present application clearer, the technical solutions of the present application will be clearly and completely described below in conjunction with the specific embodiments and corresponding drawings of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present application.

[0025] The following will, with reference to the drawings, elaborate on the technical solutions provided by each embodiment of the present application.

[0026] Please refer to Figures 1-6 , the present utility model provides a mechanical part processing and grinding device for grinding mechanical parts, which has the effect of cleaning debris and floating dust. Technical solution:

[0027] A mechanical part processing and grinding device includes a workbench 1. The upper surface of the workbench 1 is fixedly connected with a grinding assembly 2. The upper surface of the workbench 1 is provided with mounting holes, and the inner wall of the mounting holes is fixedly connected with a grille plate 3. The lower surface of the workbench 1 is fixedly connected with a box body 4. The surface of the box body 4 is provided with through holes, and the inner wall of the through holes is fixedly connected with a blower 5. The inner wall of the box body 4 is fixedly connected with a filter screen 6. The filter screen 6 is arranged between the grille plate 3 and the blower 5. By setting the blower 5, a negative pressure is formed in the box body 4, and then the dust generated by grinding is sucked into the box body 4. By setting the filter screen 6 to block the dust, it is prevented from entering the external environment again, and the dust is prevented from diffusing in the surrounding air and being inhaled by the human body. It also includes a clamping component, which is a prior art and has been disclosed in the relevant technology and is not shown in the figure.

[0028] The inner wall of the box body 4 is fixedly connected with a slide bar 7. The surface of the slide bar 7 is slidably connected with a moving plate 8. One side of the moving plate 8 close to the filter screen 6 is fixedly connected with a scraper 9. By setting the moving plate 8 to drive the scraper 9 to move, the debris attached to the surface of the filter screen 6 is scraped off to prevent it from blocking the filter screen 6.

[0029] The front surface of the moving plate 8 is provided with a threaded hole, and the inner wall of the threaded hole is threadedly connected with a threaded lead screw 10. The two ends of the threaded lead screw 10 are respectively rotatably connected to the front and rear inner walls of the box body 4. The front surface of the box body 4 is fixedly connected with a driving motor 11. The output end of the driving motor 11 penetrates the inner wall of the box body 4 and is fixedly connected with one end of the threaded lead screw 10. By driving the output end of the driving motor 11 to drive the threaded lead screw 10 to rotate, the moving plate 8 is driven to move under the cooperation of the slide bar 7.

[0030] One side of the moving plate 8 is fixedly connected with a cleaning plate 12. The front and rear sides of the inner bottom wall of the box body 4 are both provided with cleaning openings 13 for discharging debris. By driving the cleaning plate 12 to move by the moving plate 8, the debris falling on the inner bottom wall of the box body 4 is pushed to move so that it falls into the cleaning openings 13 and is discharged, having an automatic cleaning effect.

[0031] The inner wall of the box body 4 is provided with a chute, and the inner wall of the chute is slidably connected with a sliding plate 14. The upper surface of the sliding plate 14 is fixedly connected with a transmission bar 15. The opposite surfaces of the two transmission bars 15 are fixedly connected with a fixing rod 16. The front and rear surfaces of the box body 4 are both provided with sliding holes, and the fixing rod 16 is slidably connected with the inner wall of the sliding holes. One end of the fixing rod 16 is fixedly connected with a limiting block 17. The surface of the fixing rod 16 is sleeved with a spring 18. One end of the spring 18 is fixedly connected with the box body 4, and the other end of the spring 18 is fixedly connected with the limiting block 17. By setting the sliding plate 14, in cooperation with the spring 18, the cleaning openings 13 are closed under normal conditions. When the moving plate 8 moves, it pushes the transmission bar 15, and then drives the sliding plate 14 to move outward to open the cleaning openings.

[0032] The lower surface of the workbench 1 is connected with a guiding groove 19. The inner wall of the guiding groove 19 is inclined, and a communication port 20 is formed at the center of the bottom of the guiding groove 19. By arranging the guiding groove 19, the debris accumulates at the middle part of the inner bottom wall of the box body 4.

[0033] The grinding assembly 2 includes a support frame 201 fixedly connected to the upper surface of the workbench 1. A connecting plate 202 is slidably connected to the inner wall of the support frame 201. The lower surface of the connecting plate 202 is fixedly connected with a mounting frame 203. A grinding motor 204 is fixedly connected to the inner bottom wall of the mounting frame 203. The output end of the grinding motor 204 penetrates through the lower surface of the mounting frame 203 and is fixedly connected with a grinding disc 205. An electric push rod 206 is fixedly connected to the upper surface of the support frame 201. The output end of the electric push rod 206 penetrates through the inner top wall of the support frame 201 and is fixedly connected with the connecting plate 202. The output end of the grinding motor 204 drives the grinding plate to rotate to grind the mechanical parts. The output end of the electric push rod 206 drives the connecting plate 202 to move, and then drives the grinding motor 204 and the grinding disc 205 to move to adjust their heights.

[0034] Working principle: When the mechanical part processing and grinding device is used, the user first places the part to be ground on the grating plate 3 and then fixes it by using the clamping component. Then the grinding motor 204 is started. The output end of the grinding motor 204 drives the grinding plate to rotate to grind the mechanical part. When necessary, the electric push rod 206 is started. The output end of the electric push rod 206 drives the connecting plate 202 to move. The connecting plate 202 drives the grinding motor 204 and the grinding disc 205 to move to adjust their heights. At the same time, the fan 5 is started. The fan 5 makes a negative pressure in the box body 4, and then sucks the dust generated by grinding into the box body 4. The filter screen 6 is used to block the dust to prevent it from entering the external environment again. When the filter screen 6 needs to be cleaned, the driving motor 11 is started. The output end of the driving motor 11 drives the threaded lead screw 10 to rotate. The threaded lead screw 10 drives the moving plate 8 to move in cooperation with the sliding rod 7. The moving plate 8 drives the scraping plate 9 to move to scrape off the debris attached to the surface of the filter screen 6 to prevent it from blocking the filter screen 6. At the same time, the moving plate 8 drives the cleaning plate 12 to move to push the debris falling on the inner bottom wall of the box body 4 to move so that it falls into the cleaning port 13 and is discharged, having the effect of automatic cleaning. Thus, the mechanical part processing and grinding device solves the problem that there are more debris and floating dust in the prior art, which affects human health.
