[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0031] Referring to Figure 1 - Figure 2 , an embodiment provided by the present invention: a processing tool for engine valves, including a bottom plate 1. A first support plate 2 is fixedly connected to the upper surface of the bottom plate 1. A fixing plate 3 is fixedly connected to the side wall of the first support plate 2. A slider 5 is arranged inside the fixing plate 3. A first hydraulic rod 4 is fixedly connected to the side wall of the first support plate 2. The output end of the first hydraulic rod 4 penetrates through the top fixing plate 3 and is fixedly connected to the side wall of the slider 5. A connecting plate 6 is fixedly connected to the side wall of the slider 5. A chute 7 is opened inside the fixing plate 3. The side wall of the slider 5 is slidably connected inside the chute 7. A turntable 8 is rotatably connected to the side wall of the first support plate 2. A connecting block 9 is rotatably connected to the side wall of the turntable 8. Fixed rings 10 are fixedly connected to one ends of the connecting plates 6. A limiting block 11 is fixedly connected to the other end of the bottom connecting plate 6. One end of the connecting block 9 is rotatably connected to the side wall of the connecting plate 6.

[0032] When operating this device to process the engine valves, first start the first hydraulic rod 4. After the first hydraulic rod 4 starts to work, its output end will push the slider 5 to slide along the inside of the chute 7. As the slider 5 moves, the connecting plate 6 connected to it will also move accordingly. At the same time, the movement of the connecting plate 6 drives the connecting block 9 to rotate, and this rotation further causes the turntable 8 to start rotating. During this rotation process, under the combined action of the thrust of the fixed ring 10 on the connecting plate 6 and the rotational force of the turntable 8, it moves inward and finally realizes the fixing effect on the valve.

[0033] Referring to Figure 3 - Figure 4, on the upper surface of the bottom plate 1, there is a second support plate 12. On the side wall of the second support plate 12, there is a motor 13. The output end of the motor 13 is fixedly connected to a grinding block 15. On the side wall of the second support plate 12, there is a protective shell 14 fixedly connected. The protective shell 14 is arranged outside the grinding block 15. At the bottom of the second support plate 12, there is a clamping block 16. On the upper surface of the bottom plate 1, there is a first fixing block 17 fixedly connected. Inside the first fixing block 17, there is a second hydraulic rod 18. Inside the bottom plate 1, there is a first clamping groove 19. The side wall of the clamping block 16 is slidably connected inside the first clamping groove 19. The output end of the second hydraulic rod 18 is fixedly connected to the side wall of the clamping block 16. On the lower surface of the bottom plate 1, there is a water tank 29. Inside the bottom plate 1, there is a second clamping groove 28. The side wall of the water tank 29 is slidably connected inside the second clamping groove 28. Inside the bottom plate 1, there is a filter tank 26. Inside the filter tank 26, there is a filter screen 25. On one side of the bottom plate 1, there is an auxiliary component which is used to pull other components. On the upper surface of the bottom plate 1, there is a water pump 20. Both the input end and the output end of the water pump 20 are fixedly connected with a hose 21. On the upper surface of the bottom plate 1, there is a support plate 22 fixedly connected. On the upper surface of the support plate 22, there is a second fixing block 23 fixedly connected. The side wall of the top hose 21 penetrates through the inner wall of the second fixing block 23 and extends to the outside. The auxiliary component includes a first handle 27 and a second handle 31. The lower surface of the first handle 27 is fixedly connected to the upper surface of the filter screen 25. The side wall of the second handle 31 is fixedly connected to the side wall of the water tank 29. One end of the top hose 21 is fixedly connected to a nozzle 24. One end of the bottom hose 21 penetrates through the side wall of the bottom plate 1 and extends into the water tank 29. On the lower surface of the bottom plate 1, there are support columns 30 fixedly connected.

[0034] Start the second hydraulic rod 18 to drive the clamping block 16 to move. The clamping block 16 further drives the second support plate 12 to move, thereby guiding the grinding block 15 to move to the designated position. Then start the motor 13 to drive the grinding block 15 to rotate and grind the valve of the engine. After the grinding work is completed, start the water pump 20. The input end of the water pump 20 draws water from inside the water tank 29, and then conveys the water to the hose 21 through the output end, and finally reaches the nozzle 24. Use the water flow to cool the grinding area and clean the residual substances generated during the grinding process. Then the water flow passes through the filter screen 25, enters the filter tank 26, and after being filtered, enters the water tank 29 again to complete the entire circulation process.

[0035] Working principle: When using this device to process the engine valve, first start the first hydraulic rod 4. The output end of the first hydraulic rod 4 pushes the slider 5 to move inside the chute 7. The slider 5 drives the connecting plate 6 to move, so that the connecting plate 6 drives the connecting block 9 to rotate, and then causes the turntable 8 to rotate. At this time, under the thrust of the connecting plate 6 and the rotation of the turntable 8, the fixed ring 10 moves inward to fix the valve. Next, start the second hydraulic rod 18 to drive the clamping block 16 to move. The clamping block 16 drives the second support plate 12 to move, and then drives the grinding block 15 to reach the specified position. Start the motor 13 to drive the grinding block 15 to rotate to grind the engine valve. Subsequently, start the water pump 20. The input end of the water pump 20 draws water from the inside of the water tank 29 and then conveys the water from the output end into the hose 21 to reach the nozzle 24 to cool the grinding area and wash away the residues generated during grinding. The water flow enters the filter tank 26 after passing through the filter screen 25. The water flow is filtered and finally enters the water tank 29 to complete the cycle.

[0036] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
