An object is placed on the top of the fixing mechanism, and the object is clamped and fixed by the fixing mechanism to keep the object stable, avoid shaking during the operation, and prevent affecting the subsequent polishing effect. The sliding block slides on the outside of the polishing frame body to facilitate adjusting the height of the component, so as to meet the operation requirements of different heights. One side of the outside of the sliding block is fixedly connected to a receiving block. The top of the receiving block is fixedly connected to a motor. The inside of the receiving block is rotatably connected to a central rotating shaft. The motor controls the central rotating shaft to rotate. The central rotating shaft drives the grinding mechanism to rotate, so as to polish the valve body ring, thereby realizing the polishing operation of the object. The output end of the motor is fixedly connected to the top of the central rotating shaft. The bottom of the central rotating shaft is fixedly connected to an adapter block. The bottom of the adapter block is fixedly connected to a receiving piece. The grinding mechanism is inserted and connected to the inside of the receiving piece.

A strip-shaped groove is opened on one side of the outside of the silica gel strip. By opening the strip-shaped groove, the texture of the component is increased, so as to increase the friction performance of the component, further improve the fixing effect on the component, and at the same time play a certain anti-slip effect through the slotting, preventing the component from derailing during the operation process.

[0006] Preferably, the grinding mechanism includes a grinding frame body. The grinding frame body is driven to rotate by a central rotating shaft, so that the friction block rubs the surface of the object, thereby achieving the polishing operation of the object. A cylindrical outer shell is fixedly connected to the inner side of the grinding frame body. A first spring is fixedly connected to the inner side of the cylindrical outer shell. A sliding rod is slidably connected to the inner wall of the cylindrical outer shell. One side of the outside of the first spring is fixedly connected to the outside of the sliding rod.

When the friction block rubs the surface of the object, the first spring is squeezed by the sliding rod, so as to play a role of shock absorption and buffering, reduce the collision generated when attaching to the object, and avoid damaging the component. Block surface grooves are opened on the outside of the friction block.

[0008] Preferably, the supporting mechanism includes a cylindrical housing, the top of the cylindrical housing is fixedly connected to the bottom of the fixing base, and a second electric push rod is fixedly connected to the bottom inside the cylindrical housing.

The top of the second electric push rod is fixedly connected to a receiving plate, the top of the receiving plate is fixedly connected to a support frame body, and a third electric push rod is fixedly connected to the outside of the support frame body. There are certain differences in the types of plug valves, resulting in different shapes of objects. When a single clamping block is used to clamp the object, there is a certain degree of clamping instability.

[0013] The present invention provides a polishing device for processing a double-sealed cock valve. It has the following beneficial effects: First, for the polishing device for processing the double-sealed cock valve, through the design of the polishing mechanism, the object is placed on the top of the fixing mechanism, and the object is clamped and fixed by the fixing mechanism to keep the object stable, avoid shaking during the operation, and prevent affecting the subsequent polishing effect. The sliding block slides on the outside of the polishing frame body to facilitate adjusting the height of the component, so as to meet the operation requirements of different heights. The motor controls the central shaft to rotate, and the central shaft drives the grinding mechanism to rotate, so as to polish the valve body ring, thereby realizing the polishing operation of the object. After a long time of operation, the surface of the grinding mechanism is severely worn and needs to be replaced. After the grinding mechanism is inserted into the inner side of the receiving piece, the grinding mechanism is clamped by the disassembly mechanism to quickly fix the component, so as to facilitate replacement, reduce the difficulty of replacement operation, and improve the operation efficiency.

[0014] Second, for the polishing device for processing the double-sealed cock valve, through the design of the disassembly mechanism, the first electric push rod controls the U-shaped block to expand and contract to squeeze and clamp the grinding mechanism, so as to realize the fixing of the component, facilitate the subsequent replacement of the component, and improve the operation efficiency. The silicone strip is made of silicone material to increase the wear resistance and buffering effect of the component, play a certain protective effect on the component, avoid excessive friction between components, prevent serious wear of the components, and thus extend the service life of the components. By opening strip-shaped grooves to increase the texture of the component, the friction performance of the component is increased, and the fixing effect on the component is further improved. At the same time, the slotting plays a certain anti-slip effect to prevent the component from derailing during the operation.

[0015] III. The polishing equipment for processing the double-sealed plug valve drives the polishing frame to rotate through the central rotating shaft by designing the grinding mechanism, so that the friction block rubs against the surface of the object, thereby achieving the polishing operation of the object. By opening the surface groove, the surface texture of the friction block is increased, thereby further improving the friction performance, and thus increasing the polishing effect on the surface of the object. At the same time, slotting plays a certain heat dissipation effect, reducing the local heat on the surface of the component, so as to avoid affecting the performance of the component. When the friction block rubs against the surface of the object, the first spring is squeezed by the sliding rod, thereby playing a role of shock absorption and buffering, reducing the collision generated when attaching to the object, and avoiding damage to the component.

[0016] IV. The polishing equipment for processing the double-sealed plug valve controls the lifting of the support frame through the second electric push rod by designing the support mechanism, thereby avoiding collision when placing the object, thus playing a certain protective role for the equipment and keeping the equipment running normally. There are certain differences in the types of plug valves, resulting in different shapes of the objects. When clamping the object with a single clamping block, there is a certain degree of unstable clamping. Therefore, the third electric push rod is used to control the telescopic movement of the receiving plate inside the object wall, thereby achieving the extrusion of the object wall, and thus realizing the fixing effect of the object, improving the fixing effect, realizing different types of fixing effects, and at the same time adapting to the clamping block, thereby achieving the positioning effect of the object, facilitating the adjustment of the clamping position of the object, and avoiding the situation of polishing deviation.

[0017] V. The polishing equipment for processing the double-sealed plug valve drives the support plate to expand and contract through the third electric push rod by designing the buffer mechanism. When the circular block contacts the inner wall of the object, the circular block drives the connecting rod to squeeze and contract the second spring, thereby achieving the effect of shock absorption and buffering, avoiding excessive pushing pressure, preventing the influence on the equipment performance, and thus prolonging the service life of the component. Secondly, by contracting the second spring, it is convenient to adjust according to the shape of the inner wall of the object, so as to facilitate fitting the inner wall of the object, thereby further improving the fixing effect, playing a certain anti-slip effect, protecting the component through the silicone block, reducing the wear of the component, and playing a certain buffer effect.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] The first embodiment, as Figures 1 to 5As shown in the figure, the present invention provides a technical solution: a polishing device for processing a double-sealed cock valve, including a polishing mechanism 1. The bottom of the polishing mechanism 1 is fixedly connected to a workbench 4. A fixing mechanism 2 is rotatably connected to the top of the workbench 4.

A motor 14 is fixedly connected to the top of the receiving block 13. A central rotating shaft 15 is rotatably connected to the inside of the receiving block 13. The output end of the motor 14 is fixedly connected to the top of the central rotating shaft 15. A connecting block 16 is fixedly connected to the bottom of the central rotating shaft 15. A receiving piece 17 is fixedly connected to the bottom of the connecting block 16. A polishing mechanism 19 is inserted and connected to the inside of the receiving piece 17. A disassembly mechanism 18 is fixedly connected to the top of the receiving piece 17. Place the object on the top of the fixing mechanism 2, and clamp and fix the object through the fixing mechanism 2 to keep the object stable, avoid shaking during the operation, and prevent affecting the subsequent polishing effect. The sliding block 12 slides on the outside of the polishing frame body 11 to facilitate adjusting the height of the component, so as to meet the operation requirements of different heights. The motor 14 controls the central rotating shaft 15 to rotate, and the central rotating shaft 15 drives the polishing mechanism 19 to rotate, so as to polish the valve body ring, thereby realizing the polishing operation of the object. After a long time of operation, the surface of the polishing mechanism 19 is severely worn and needs to be replaced. After the polishing mechanism 19 is inserted into the inside of the receiving piece 17, the disassembly mechanism 18 clamps the polishing mechanism 19 to quickly fix the component, so as to facilitate replacement, reduce the difficulty of replacement operation, and improve the operation efficiency.

[0022] The disassembly mechanism 18 includes a disassembly frame body 181. A first electric push rod 182 is fixedly connected to the inside of the disassembly frame body 181. A U-shaped block 183 is fixedly connected to one side of the outside of the first electric push rod 182. A silica gel strip 184 is fixedly connected to the outer arc of the U-shaped block 183. A strip-shaped groove 185 is opened on one side of the outside of the silica gel strip 184. Control the U-shaped block 183 to expand and contract through the first electric push rod 182 to squeeze and clamp the polishing mechanism 19, so as to realize the fixing function of the component, facilitate the subsequent replacement of the component, and improve the operation efficiency. The silica gel strip 184 is made of silica gel material to increase the wear resistance and buffering effect of the component, play a certain protective effect on the component, avoid excessive friction between components, prevent the components from being severely worn, and thus extend the service life of the components. By opening the strip-shaped groove 185 to increase the texture of the component, the friction performance of the component is increased, the fixing effect on the component is further improved, and at the same time, the anti-slip effect is achieved through the slotting to prevent the component from derailing during the operation.

[0023] The grinding mechanism 19 includes a grinding frame body 191. Inside the grinding frame body 191, a cylindrical outer shell 192 is fixedly connected.

A block surface groove 196 is opened on the outside of the friction block 195. The grinding frame body 191 is driven to rotate by the central rotating shaft 15, so that the friction block 195 rubs against the surface of the object, thereby achieving the polishing operation of the object. By opening the block surface groove 196, the surface texture of the friction block 195 is increased, thereby further improving the friction performance, so as to increase the polishing effect on the surface of the object. At the same time, through the slotting, a certain heat dissipation effect is achieved, reducing the local heat on the surface of the component, so as to avoid affecting the performance of the component. When the friction block 195 rubs against the surface of the object, the first spring 193 is compressed by the sliding rod 194, thereby playing a role of shock absorption and buffering, reducing the collision generated when attaching to the object, and avoiding damage to the component.

[0024] The second embodiment, on the basis of the first embodiment, please refer to Figures 6 to 8 As shown, the fixing mechanism 2 includes a driven block 21.

A connecting belt 22 is rotatably connected to the outside of the driven block 21. On the side of the outside of the connecting belt 22 away from the driven block 21, a driving block 23 is rotatably connected. The top of the driving block 23 is fixedly connected to a connecting end 24. The top of the connecting end 24 is fixedly connected to a support mechanism 25. The outside of the support mechanism 25 is fixedly connected to a fixing base 26. A slide rail block 27 is fixedly connected to the groove at the top of the fixing base 26. A clamping block 28 is slidably connected to the outside of the slide rail block 27. The rotation of the driven block 21 is controlled by the motor 5. The driven block 21 controls the connecting belt 22 to drive the driving block 23 to rotate. The fixing base 26 is driven to rotate by the driving block 23, thereby driving the object to perform a rotating operation and adapting to the grinding mechanism 19. Thus, by rotating the object at a constant speed and rubbing it against the grinding mechanism 19, the uniform polishing of the object is realized, avoiding damage to the surface of the object. Rotation can evenly distribute heat on the entire surface, reduce local overheating phenomena, reduce the risk of surface damage, and improve the polishing efficiency.

There are certain differences in the types of stop valves, resulting in different shapes of objects. When clamping an object with a single clamping block 28, there is a certain degree of unstable clamping. Therefore, the third electric push rod 255 is used to control the receiving plate 253 to expand and contract inside the object wall, so as to achieve extrusion of the object wall, thereby realizing the fixing effect of the object, improving the fixing effect, realizing different types of fixing effects, and at the same time adapting to the clamping block 28, so as to achieve the role of positioning the object, facilitating the adjustment of the clamping position of the object, and avoiding the situation of polishing deviation.

A blower 35 is fixedly connected to one side of the outside of the connecting pipe 34. During the polishing process of the object, metal debris and gas are easily generated. The blower 35 generates wind power, and the receiving platform 32 rotates on the annular track 31, driving the cleaning housing 33 to rotate on the surface of the object, so as to collect the debris on the object and the top of the workbench 4, thereby achieving the cleaning effect on the object and the equipment, reducing the debris on the surface of the equipment, avoiding the penetration of debris into the interior of the equipment, preventing the increase of wear between components caused by debris, thus affecting the use effect of the equipment, and at the same time reducing the damage of debris to the object, reducing the scratches on the surface of the object, and improving the product quality.

A collecting housing 37 is inserted and connected to the outside of the square incision 36. A rotating mechanism 38 is fixedly connected to one side of the inner wall of the connecting pipe 34. The blower 35 generates wind power, causing the debris and dust to flow from one side of the cleaning housing 33 to the connecting pipe 34, so as to achieve the effect of dispersing the gas, accelerating the gas discharge, reducing the irritation of the gas to the human body, optimizing the working environment, reducing the potential safety hazards to the human body. The wind power drives the rotating mechanism 38 to rotate, thereby rubbing the inner wall of the connecting pipe 34, reducing the adsorption of debris, and causing the debris to fall into the interior of the collecting housing 37, so as to achieve the collection effect on the debris and facilitate subsequent cleaning.

[0029] The rotating mechanism 38 includes a connecting shaft 381. A rotating column 382 is rotatably connected to the outside of the connecting shaft 381.

[0030] In use, the staff places the plug valve on the top of the fixing mechanism 2. The clamping block 28 slides on the top of the fixed base 26 to clamp the plug valve, thereby fixing the object, keeping the object balanced and stable, and facilitating subsequent operations. Secondly, a support mechanism 25 is arranged inside the fixing mechanism 2. There are certain differences in the types of plug valves, resulting in different shapes. During the process of clamping the object by the clamping block 28, there is a certain degree of instability, which easily affects the polishing effect of the object. To avoid affecting the polishing accuracy, the support mechanism 25 squeezes and supports from inside the plug valve to fix the object. The support mechanism 25 is clamped and adapted to the clamping block 28 to play a certain positioning role, keeping the object in the central position and avoiding misalignment from affecting the polishing accuracy. After fixing the plug valve, the sliding block 12 inside the polishing mechanism 1 slides on the polishing frame 11 to adjust the height of the equipment, facilitating the operation requirements of different objects. The motor 14 controls the central rotating shaft 15 to rotate, enabling the grinding mechanism 19 to friction inside the plug valve, thereby realizing the polishing operation of the object. The grinding mechanism 19 has adaptability to different ring sizes, increasing the applicable range of the component. During the grinding process of the object, irritating odors are easily generated. The cleaning mechanism 3 absorbs and discharges the gas, accelerating the dissipation effect of the gas and avoiding the impact of the gas on the human body, optimizing the working environment. At the same time, the debris on the surface of the object is cleaned and collected to prevent the debris from scattering. After taking out the object, the cleaning mechanism 3 cleans the surface of the workbench 4, reducing the debris on the surface of the workbench 4, preventing the debris from entering the equipment interior, reducing the wear between components, and thus prolonging the service life of the components.
