Description

Technical Field

[0001] This utility model relates to the field of grinding equipment technology, specifically a precision grinding tool for special valve sealing surfaces. Background Technology

[0002] Special valves are valves that have special structures, materials, processes, functions, or are suitable for special working conditions compared to ordinary industrial valves. Special valves are mainly used in special environments such as high temperature, high pressure, and corrosive environments to meet the requirements of these special environments.

[0003] During the use of special valves, the sealing surface may be damaged, worn or deformed due to long-term use, improper operation or media corrosion, resulting in a decrease in sealing performance. Grinding can repair the damaged surface and restore it to a smooth state, thereby ensuring sealing performance.

[0004] The prior art patent document CN210732121U provides a conical valve sealing surface grinding tool. This grinding tool can firmly fix the workpiece to be ground on the upper surface of the stage by setting a clamping block. By setting a lifting arm, the grinding blade can be quickly moved to the vicinity of the workpiece to be ground. By setting a fine adjustment wheel, the grinding surface can be brought into close contact with the surface to be ground of the workpiece. By observing the changes in the scale on the fine adjustment wheel, the degree of grinding of the grinding surface can be accurately known, thus improving the grinding accuracy of the workpiece.

[0005] Although the existing technology described above can firmly fix the workpiece to be ground on the upper surface of the stage by setting clamping blocks, thus achieving the effect of limiting and fixing the workpiece, the grinding tool in this patented technology generates a lot of dust during the grinding process, which affects the workers working nearby and pollutes the grinding production environment. It requires subsequent cleaning by the workers, which is very troublesome. Therefore, we need a special precision grinding tool for valve sealing surfaces. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 A special precision grinding tool for valve sealing surfaces includes a base 1, a drive mechanism 2 is provided inside the base 1, a dust collection component 3 is installed on the top of the base 1, and a clamping component 8 is provided on the top of the drive mechanism 2.

[0027] The vacuuming assembly 3 includes a fixed box 301, an exhaust box 302 fixedly connected to the top of the fixed box 301, a connecting pipe 303 installed on one side of the exhaust box 302, a flexible hose 304 fixedly connected to one end of the connecting pipe 303, and a vacuuming pipe 305 installed at one end of the flexible hose 304. A slot 306 is provided on the top of the exhaust box 302, and a dustproof net 307 is engaged with the inner wall of the slot 306. A sliding groove 308 is provided on the front of the fixed box 301, and a collection box 309 is slidably connected to the inner wall of the sliding groove 308.

[0028] The clamping assembly 8 includes a movable plate 801. A connecting groove 802 is provided on one side of the movable plate 801, and a connecting block 803 is engaged with the inner wall of the connecting groove 802. A clamping plate 804 is fixedly connected to one side of the connecting block 803. A positioning groove 805 is provided on the top of the connecting block 803, and a positioning rod 806 is engaged with the inner wall of the positioning groove 805. A spring 807 is installed on the top of the positioning rod 806, and a pull rod 808 is sleeved on the inner wall of the spring 807.

[0029] Through the above technical solution, by activating the exhaust fan in the exhaust box 302, the dust suction pipe 305 can generate suction, sucking the dust generated during grinding into the connecting pipe 303. The hose 304 allows the dust suction pipe 305 to move up and down with the grinding mechanism 7. The dustproof net 307 can intercept the dust, and the intercepted dust will enter the collection box 309 for collection. The collection box 309 can slide out from the slide groove 308, allowing the dust in the collection box 309 to be cleaned, thus improving the environment for grinding workpieces.

[0030] Specifically, a support plate 4 is fixedly connected to the top of the base 1, and a fixing plate 5 is installed on one side of the support plate 4. A hydraulic cylinder 6 is provided on the top of the fixing plate 5, and a grinding mechanism 7 is installed at the output end of the hydraulic cylinder 6.

[0031] The above technical solution facilitates the installation of the hydraulic cylinder 6 on the fixed plate 5 and its support by the support plate 4. Activating the hydraulic cylinder 6 can drive the grinding mechanism 7 to move up and down, thereby moving the grinding mechanism 7 downward to grind the workpiece.

[0032] Specifically, the fixed box 301 forms a fixed structure with the exhaust box 302 and the connecting pipe 303, and the flexible hose 304 is arranged between the connecting pipe 303 and the suction pipe 305.

[0033] The above technical solution facilitates the activation of the exhaust fan inside the exhaust box 302, which enables the connecting pipe 303 to generate suction, and then the suction pipe 305 to generate suction through the hose 304. One end of the suction pipe 305 is connected to the grinding mechanism 7. During the grinding process, the grinding mechanism 7 moves up and down synchronously, allowing the dust generated during grinding to be sucked in. The hose 304 enables the suction pipe 305 to move up and down, thereby achieving the effect of sucking the dust into the exhaust box 302.

[0034] Specifically, the exhaust box 302 forms an engaging structure with the dustproof net 307 through the slot 306, and the shape and size of the slot 306 match the shape and size of the dustproof net 307.

[0035] The above technical solution facilitates the interception and filtration of dust entering the exhaust box 302 by the dustproof net 307. The first purpose is to intercept and allow the dust to fall, and the second purpose is to reduce the impact of dust entering the exhaust fan.

[0036] Specifically, the fixed box 301 forms a sliding structure with the collection box 309 through the slide groove 308, and the shape and size of the slide groove 308 match the shape and size of the collection box 309.

[0037] The above technical solution facilitates the collection of dust intercepted by the dustproof net 307 into the collection box 309. Workers can manually pull the collection box 309 out of the slide 308 and then clean the dust inside the collection box 309.

[0038] Specifically, the movable plate 801 forms a locking structure with the connecting block 803 through the connecting groove 802, and the shape and size of the connecting groove 802 match the shape and size of the connecting block 803.

[0039] The above technical solution facilitates the formation of a detachable structure between the movable plate 801 and the clamping plate 804 via the connecting groove 802 and the connecting block 803, allowing the clamping plate 804 to be installed with the movable plate 801 by extending into the connecting groove 802 via the connecting block 803, and enabling the clamping plate 804 to be replaced.

[0040] Specifically, the connecting block 803 forms a locking structure with the positioning rod 806 through the positioning groove 805, and the shape and size of the positioning groove 805 match the shape and size of the positioning rod 806. The moving plate 801 forms an elastic structure with the positioning rod 806 through the spring 807.

[0041] The above technical solution facilitates the upward movement of the positioning rod 806 by pulling the lever 808, thereby causing the positioning rod 806 to disengage from the positioning groove 805 and release the limiting fixation on the connecting block 803. When the lever 808 is released, the positioning rod 806 will extend into the positioning groove 805 under the elastic action of the spring 807 to limit and fix the connecting block 803, thus achieving the effect of fixing and releasing the clamping plate 804.

[0042] Working principle: When using this special valve sealing surface precision grinding tool, first, replace the corresponding clamping plate 804 according to the valve's shape. Pull the pull rod 808 by hand. The pull rod 808 drives the positioning rod 806 to move upward. The positioning rod 806 disengages from the positioning groove 805, releasing the limiting fixation on the connecting block 803. Pull out the clamping plate 804 and insert the connecting block 803 on one side of the corresponding clamping plate 804 into the connecting groove 802 to connect with the moving plate 801. Then, release the pull rod 808. Under the elastic action of the spring 807, the positioning rod 806 extends into the positioning groove 805 to fix the connecting block 803. Then, start the drive mechanism 2 to make the moving plate 801 move inward. The valve is clamped and fixed by the moving mechanism. The hydraulic cylinder 6 is activated, causing the grinding mechanism 7 to move downward to grind the valve. The exhaust fan in the exhaust box 302 is activated, causing the suction pipe 305 to generate suction. As the grinding mechanism 7 moves downward, the suction pipe 305 moves synchronously through the hose 304, thereby drawing dust into the exhaust box 302. The dust is intercepted by the dustproof net 307 in the exhaust box 302, and the intercepted dust falls into the collection box 309 for collection. The collection box 309 can be pulled out through the slide 308 for cleaning. This completes all the work. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit defined by the appended claims and their equivalents.
