Description

Technical Field

[0001] This utility model relates to the field of valve seal processing technology, and in particular to a positioning device for valve seal processing. Background Technology

[0002] Valve seals are usually critical components in valve structures. Their machining accuracy and quality directly affect the valve's sealing performance and service life. Therefore, in order to ensure the machining quality of valve seals, it is usually necessary to use positioning chucks or fixtures to fix and position the workpiece to ensure the stability and accuracy of the workpiece position during the machining process.

[0003] According to the patent application CN222609358U, "This utility model relates to the valve sealing component processing industry, and particularly to a positioning chuck for valve sealing component processing. Technical problem: Existing valve sealing component positioning chucks are generally inconvenient for quickly and stably positioning the inner and outer walls of metal rings, the positioning mechanism is inconvenient to adjust, and the positioning effect is poor. Technical solution: A positioning chuck for valve sealing component processing includes a moving component; it also includes a supporting component, a pressing component, a limiting component, a central positioning component, a chuck assembly, and a sealing component body. This utility model limits the inner wall of the sealing component body through the central positioning component, and after the limiting component is installed, it limits the outer wall of the sealing component body. The chuck assembly can press and fix the outer wall of the sealing component body, and then the pressing component is activated to press and fix the upper end of the sealing component body, thus achieving rapid and stable positioning of the sealing component body. Furthermore, the positioning mechanism is easy to adjust."

[0004] Regarding the above description, the applicant believes the following problems exist: The device limits the inner wall of the sealing element body through the central positioning component, and then limits the outer wall of the sealing element body after the limiting component is installed. It is only suitable for sealing elements of a single specification and lacks size adjustment function, resulting in poor adaptability to sealing elements of different sizes. At the same time, since the device does not have a sealing element rotation mechanism, when the sealing element needs to be processed at multiple angles, the operator cannot easily adjust the position of the workpiece, which seriously affects the processing efficiency and ease of operation. Utility Model Content

An outer clamping plate is slidably connected to the inside of the fixed plate. A fixing component two is fixedly connected to the bottom of the outer clamping plate. An inner support clamping assembly is provided on the fixed plate, and a rotating assembly is provided at the bottom of the processing table.

[0007] Preferably, the internal support clamping assembly includes a motor, which is fixedly connected to the bottom of the fixed plate. The output end of the motor is fixedly connected to a worm gear, and the worm gear is externally meshed with a turbine. The motor drives the worm gear to rotate the turbine.

The fixed plate is internally slidably connected to a slider, and an internal support plate is fixedly connected to the slider. A limit rod is fixedly connected to the end of the slider away from the internal support plate.

[0008] Preferably, when the moving plate moves downward, the outer clamping plate moves closer to the electric push rod, and when the moving plate moves upward, the outer clamping plate moves away from the electric push rod.

[0009] Preferably, the second fixing member has a through hole, and the movable block is rotatably connected to the inside of the second fixing member through the through hole.

[0010] Preferably, when the turntable rotates, the slider causes the inner support plate to expand outward or contract inward.

[0011] Preferably, the rotating assembly includes a second motor, which is fixedly connected to the bottom of the processing table. The output end of the second motor is fixedly connected to a second worm gear, and the outside of the second worm gear is meshed with a second turbine.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please see Figures 1-6 This utility model provides an embodiment of a positioning device for processing valve seals, including a processing table 1; it also includes a mounting groove 201 and a rotating assembly. The mounting groove 201 is fixedly connected to the processing table 1, and a fixed plate 202 is fixedly connected to the mounting groove 201. A mounting plate 203 is fixedly connected to the bottom of the fixed plate 202, and an electric push rod 204 is fixedly connected to the mounting plate 203. A movable plate 205 is fixedly connected to the output end of the electric push rod 204. The electric push rod 204 is used to push the movable plate 205 to move. A fixing member 206 is fixedly connected to the movable plate 205, and a movable block 207 is rotatably connected to the inner side of the fixing member 206. An outer clamping plate 209 is slidably connected to the inside of the fixed plate 202, and a fixing member 208 is fixedly connected to the bottom of the outer clamping plate 209. An inner support clamping assembly is provided on the fixed plate 202. A rotating assembly is provided at the bottom of the processing table 1. The inner support clamping assembly includes a motor 210, which is fixedly connected to the fixed plate 202. At the bottom, a worm gear 211 is fixedly connected to the output end of motor 210. A worm gear 212 is externally meshed with worm 211. Motor 210 drives worm 211 to rotate worm 212. A shaft 213 is fixedly connected inside worm 212. A turntable 214 is fixedly connected to the end of shaft 213 away from worm 212. A slider 215 is slidably connected inside fixed disk 202. An inner support plate 216 is fixedly connected to slider 215. A limiting rod 217 is fixedly connected to one end of block 215 away from the inner support plate 216. When using this device, first place the seal on the fixed plate 202, start the motor 210, drive the worm gear 211 to drive the turbine 212 to rotate, so that the slider 215 drives the inner support plate 216 to expand outward and squeeze and position the inner wall of the seal. Then start the electric push rod 204 to push the moving plate 205 to move downward, so that the outer clamping plate 209 retracts inward and squeezes and positions the outer wall of the seal.

[0025] Please see Figures 1-5 In this embodiment, when the moving disk 205 moves downward, the outer clamping plate 209 approaches the electric push rod 204; when the moving disk 205 moves upward, the outer clamping plate 209 moves away from the electric push rod 204. The moving disk 205 facilitates the movement of the outer clamping plate 209. The second fixing member 208 has a through hole 1 inside, and the movable block 207 is rotatably connected to the inner side of the second fixing member 208 through the through hole 1. The through hole 1 facilitates the rotation of the movable block 207 inside the second fixing member 208. When the turntable 214 rotates, the slider 215 drives the inner support plate 216 to expand outward or contract inward. The turntable 214 facilitates the expansion and contraction of the inner support plate 216.

[0026] Please see Figure 6In this embodiment, the rotating assembly includes a second motor 301, which is fixedly connected to the bottom of the processing table 1. A second worm gear 302 is fixedly connected to the output end of the second motor 301. A second turbine gear 303 is externally meshed with the second worm gear 302. The second motor 301 drives the second worm gear 302 to rotate the second turbine gear 303. A second shaft 304 is fixedly connected inside the second turbine gear 303. A shaft retainer 305 is fixedly connected to the bottom of the processing table 1. After the seal is positioned and fixed, the second motor 301 is started to drive the second worm gear 302 to rotate the second turbine gear 303. The second shaft 304 drives the mounting groove 201 to rotate, so that the seal rotates slowly and evenly to process the seal. A second through hole is provided inside the shaft retainer 305. The second worm gear 302 is rotatably connected to the inside of the shaft retainer 305 through the second through hole. Due to the second through hole, it is beneficial for the second worm gear 302 to rotate inside the shaft retainer 305.

[0027] When the device is in operation, the seal is first placed on the fixed plate 202. The motor 210 is started, which drives the worm gear 211 to rotate the turbine 212. This causes the slider 215 to expand the inner support plate 216 to compress and position the inner wall of the seal. Then, the electric push rod 204 is started, which pushes the moving plate 205 downward, causing the outer clamping plate 209 to retract and compress and position the outer wall of the seal. After the seal is positioned and fixed, the motor 301 is started, which drives the worm gear 302 to rotate the turbine 303. The shaft 304 rotates the mounting groove 201, causing the seal to rotate slowly and uniformly for processing.

[0028] Through the above steps, when using the device, the sealing element is first placed on the fixed plate 202, the motor 210 is started, and the worm gear 211 drives the turbine 212 to rotate, causing the slider 215 to drive the inner support plate 216 to expand outward and squeeze and position the inner wall of the sealing element. Then, the electric push rod 204 is started to push the moving plate 205 to move downward, causing the outer clamping plate 209 to retract inward and squeeze and position the outer wall of the sealing element. This achieves the effect of positioning and fixing the inner and outer walls of the sealing element and processing the sealing element at multiple angles through a bidirectional adaptive clamping mechanism. It alleviates the problem of poor adaptability to sealing elements of different sizes due to the lack of size adjustment function and the inability of operators to conveniently adjust the position of the workpiece. It significantly improves the reliability of workpiece fixing, the adaptability of the device, and the processing efficiency.
