Description
Technical Field
[0001] The utility model relates to the field of valve processing devices, in particular to a fixture for grinding and cleaning valves of motorcycle engines. Background Art
[0002] The motorcycle engine valve is a vital component in the motorcycle engine. It controls the entry of air and fuel and the discharge of exhaust gas by opening and closing the intake and exhaust passages. During the long-term use of the motorcycle, the valve and valve seat will be constantly impacted, and the high-temperature and high-pressure gas will cause ablation and wear on them. This wear will cause the valve to close loosely, which will in turn affect the normal operation of the engine. In order to restore the sealing performance of the valve, it needs to be polished. The valve polishing and cleaning fixture can stably fix the valve so that it will not deviate or shake during the polishing process. This stability helps the polishing tool act more accurately on the valve surface, thereby improving the polishing efficiency and shortening the maintenance time.

[0031] 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. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0032] Referring to Figure 1 - Figure 2 , an embodiment provided by the present invention: A fixture for grinding and cleaning the valves of a motorcycle engine, including an operating table 1, a fixed frame 2 is fixedly connected to the upper surface of the operating table 1, a slide bar 3 is fixedly connected between the fixed frames 2, a plurality of slide blocks 4 are slidably connected to the side wall of the slide bar 3, an electric push rod 5 is fixedly connected to the lower surface of the right slide block 4, a fixed plate 6 is fixedly connected to the side wall of the operating table 1, a first fixed block 7 is fixedly connected to the upper surface of the fixed plate 6, the side wall of the slide bar 3 is fixedly connected inside the first fixed block 7, a second fixed block 12 is fixedly connected to the upper surface of the fixed plate 6, the output end of the electric push rod 5 is fixedly connected inside the second fixed block 12, a fixed column 8 is fixedly connected to the upper surface of the fixed plate 6, a rotating rod 9 is rotatably connected to the side wall of the fixed column 8, a connecting rod 10 is rotatably connected to the side wall of the rotating rod 9, the side wall of the connecting rod 10 is rotatably connected to the upper surface of the slide block 4, a clamping block 11 is fixedly connected to the upper surface of the slide block 4, a baffle 13 is fixedly connected to the upper surface of the operating table 1, a plurality of table legs 27 are fixedly connected to the lower surface of the operating table 1, a storage rack 28 is fixedly connected between the table legs 27, and the upper surface of the storage rack 28 is fixedly connected to the lower surface of the collection box 16;
[0033] When using this device, first start the electric push rod 5. The reset of the electric push rod 5 pulls the right slide block 4 to slide inward along the slide bar 3, triggering the linkage mechanism between the rotating rod 9 and the right connecting rod 10, causing the rotating rod 9 to deflect. The deflection of the rotating rod 9 drives the left connecting rod 10 to rotate, thereby causing the left slide block 4 to also slide inward along the slide bar 3. This clamping action ensures that the device can adapt to and firmly clamp valves of different sizes, solving the problem that traditional fixtures for grinding and cleaning the valves of a motorcycle engine can only fix valves of the same size due to their single structure. The practicability of the device is improved through the above structure.
[0034] Referring to Figure 1 、 Figure 3 and Figure 4 , a collection groove 14 is provided inside the operating table 1. A delivery pipe 15 is fixedly connected inside the operating table 1. One end of the delivery pipe 15 is fixedly connected inside the collection groove 14. A collection box 16 is arranged on the lower surface of the operating table 1. The other end of the delivery pipe 15 is fixedly connected inside the collection box 16. An exhaust fan 25 is fixedly connected to the side wall of the collection box 16. A filter plate 17 is slidably connected inside the collection box 16. A clamping block 18 is fixedly connected to the side wall of the filter plate 17. A handle 24 is fixedly connected to the side wall of the filter plate 17. A third fixing block 19 is fixedly connected inside the collection box 16. A fixing shaft 20 is fixedly connected inside the third fixing block 19. A buckle assembly is arranged inside the third fixing block 19. The buckle assembly is used to fix the filter plate 17. The buckle assembly includes a first clamping ring 21 and a second clamping ring 22. The inner wall of the first clamping ring 21 is rotatably connected to the side wall of the fixing shaft 20. The inner wall of the second clamping ring 22 is rotatably connected to the side wall of the fixing shaft 20. The side wall of the first clamping ring 21 is rotatably connected to the side wall of the second clamping ring 22. A spring 23 is arranged inside the collection box 16. One end of the spring 23 is fixedly connected to the side wall of the third fixing block 19. The other end of the upper spring 23 is fixedly connected to the side wall of the first clamping ring 21. The other end of the lower spring 23 is fixedly connected to the side wall of the second clamping ring 22. The clamping block 18 is engaged with the first clamping ring 21 and the second clamping ring 22. A drawer 26 is slidably connected inside the collection box 16.
[0035] During the grinding process, the baffle 13 effectively blocks the possible splashing of debris generated during the grinding process, ensuring that these debris do not scatter everywhere but fall into the lower collection groove 14. As the debris in the collection groove 14 gradually increases, the exhaust fan 25 can be started at this time. The suction force generated by it is used to suck the debris in the collection groove 14 into the collection box 16 through the delivery pipe 15. The collection box 16 serves as the final destination of the debris. The filter plate 17 arranged inside it plays a crucial role. The filter plate 17 can effectively block the debris from entering the exhaust fan 25 and prevent it from damaging or affecting the normal operation of the exhaust fan 25. When the debris in the collection box 16 accumulates to a certain extent, only by pulling out the drawer 26 can the debris inside the collection box 16 be taken out together for centralized treatment, simplifying the cleaning process and improving the work efficiency. In addition, by pulling the handle 24, the spring 23 can be stretched, and then the first clamping ring 21 and the second clamping ring 22 are deflected and opened outward. This action enables the originally restricted clamping block 18 to be released, so that the filter plate 17 can be successfully pulled out from the collection box 16. After cleaning the debris on the filter plate 17, only by inserting it back into the collection box 16 and ensuring that the clamping block 18 is clamped into the first clamping ring 21 and the second clamping ring 22 can the fixing of the filter plate 17 be completed, solving the problem that the traditional cleaning fixture for motorcycle engine valve grinding uses an integrated filter plate 17, resulting in difficult cleaning of the filter plate 17, and improving the practicability of the equipment through the above structure.
[0036] Working principle: When using this device, first start the electric push rod 5, which drives the right slider 4 to slide inward along the slide rod 3. Further, the rotating rod 9 and the right connecting rod 10 deflect, and the deflection of the rotating rod 9 drives the left connecting rod 10 to rotate, causing the left slider 4 to slide inward along the slide rod 3, realizing the clamping and fixing of valves of different sizes. During grinding, the baffle 13 can prevent debris from splashing and falling into the collection tank 14. Then, turn on the exhaust fan 25, so that the debris inside the collection tank 14 enters the inside of the collection box 16 through the conveying pipe 15. A filter plate 17 is also provided inside the collection box 16 to prevent debris from entering the exhaust fan 25. After collection, the debris inside can be cleaned by pulling out the drawer 26. Pull the handle 24, driving the spring 23 to be stretched, and the first snap ring 21 and the second snap ring 22 deflect and open outward, causing the clamping block 18 to break away from the restrictions of the first snap ring 21 and the second snap ring 22. Then, the filter plate 17 can be successfully pulled out and cleaned in alignment. After cleaning, insert the filter plate 17 into the inside of the collection box 16, so that the clamping block 18 is snapped into the first snap ring 21 and the second snap ring 22 to complete the fixation.
[0037] 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.
