[0011] According to the technical scheme, the first threaded rod is in threaded connection with the sleeve, the second hydraulic push plate and the second hydraulic cylinder are provided with a third spring, and the second U-shaped clamping plate and the second clamping plate are provided with a fourth spring, so that the valve is clamped by being pressed upward through the first clamping plate, and vibration of the valve during polishing is prevented, so that polishing failure is prevented and the polishing effect is improved.

[0012] According to the above technical scheme, the collecting device comprises a collecting box, a second threaded rod, a second gear, a drawer, a water tank and a fan-shaped conduit, the collecting box is slidingly installed at the top of the base, the second threaded rod is rotatably installed at the left side of the collecting box, the second gear is fixedly installed on the circumferential surface of the second threaded rod close to the first threaded rod, the drawer is slidingly installed at the bottom of the collecting box, the water tank is fixedly installed at the top of the collecting box, and the fan-shaped conduit is fixedly installed at the bottom of the water tank.

[0013] According to the above technical scheme, the collecting device further comprises a rotating valve, a valve plate, a push plate, a rotating plate, a water tank nozzle and a baffle, the rotating valve is rotatably installed at the top of the collecting box, the valve plate is fixedly installed on the inner wall of the rotating valve, the push plate is fixedly installed on the circumferential surface of the rotating valve, the rotating plate is fixedly installed on the circumferential surface of the rotating valve, the water tank nozzle is fixedly installed on the top of the inner wall of the collecting box, and the baffle is fixedly installed on the top of the collecting box.

[0014] According to the above technical scheme, the second threaded rod is threadedly connected with the collecting box, the first gear is engaged with the second gear, and the fifth spring is arranged between the rotating plate and the baffle. By rotating the valve plate, the water flow in the water tank is sprayed out from the water tank nozzle. When polishing, water is sprayed to reduce dust, so that dust and debris are more easily collected under the action of the water flow, and dust is not blown up due to high-speed polishing, so as to prevent dust from being blown up during high-speed polishing to cause collection difficulty.

[0015] The present application provides a polishing device for valve production. It has the following advantages:

[0016] (1) The present application drives the polishing head to start rotating by rotating the telescopic rod. As the rotating speed of the shaft increases, the telescopic rod gradually extends under the action of centrifugal force, so that the polishing head closely adheres to the inner wall of the valve during polishing, and the inner wall of the valve is polished clean and flat. This prevents the polishing head from not closely adhering to the inner wall of the valve, which greatly reduces the polishing effect and causes the valve to not closely adhere to the pipe wall during subsequent butt joint. The gas in the air cylinder is pushed out from the air jet pipe by moving the air cylinder push plate, so that the dust and debris generated during polishing can be blown away forward by the continuous air jet of the air cylinder, and the inner wall of the valve is cleaned. This prevents the dust and debris generated during polishing from being left on the inner wall of the valve, which affects the subsequent processing or use of the valve.

[0017] (2) In this invention, when the second U-shaped clamping plate descends to contact the first U-shaped clamping plate, the T-shaped pressure rod touches the second motor switch and presses down to turn off the second motor. This ensures that the second motor is turned off in time after the second U-shaped clamping plate and the first U-shaped clamping plate come into contact and clamp together. This prevents the second U-shaped clamping plate and the first U-shaped clamping plate from continuing to clamp after contact and causing damage. This is to prevent the second U-shaped clamping plate and the first U-shaped clamping plate from being damaged due to the second motor not being turned off and continuing to clamp. The second hydraulic push rod moves upward to push the first clamping plate to start moving upward. The first clamping plate moves upward to squeeze and clamp the valve, ensuring that the valve will not vibrate excessively during grinding. This is to prevent excessive vibration during grinding from causing grinding errors and reducing the grinding effect.

[0018] (3) In this invention, when the No. 2 U-shaped clamp moves downward, the collection box moves synchronously to wrap the other end of the valve, so that the dust and debris from grinding can be collected into the drawer at the bottom of the collection box. This ensures that all the dust and debris from grinding can be completely collected, preventing dust and debris from splashing and making cleaning difficult. The valve plate rotates to spray water from the water tank nozzle, which sprays water to suppress dust during grinding. This makes it easier to collect dust and debris under the action of water flow, and prevents dust from being raised due to high-speed grinding, thus preventing dust from being raised during high-speed grinding and causing collection difficulties.

The polishing head 306 starts to rotate by rotating the extension rod 305, and the extension rod 305 gradually extends under the action of centrifugal force as the rotating speed of the rotating shaft 303 increases, so that the polishing head 306 closely adheres to the inner wall of the valve during polishing, and the inner wall of the valve is polished clean and flat, so as to prevent the polishing head 306 from not closely adhering to the inner wall of the valve, which greatly reduces the polishing effect and causes the valve to not closely adhere to the pipe wall during subsequent butt joint.

[0030] The side of the push block 307 in contact with the sliding rod 308 is provided with an inclined surface, the side of the sliding rod 308 in contact with the vertical rod 309 is provided with an inclined surface, the side of the vertical rod 309 in contact with the air cylinder push rod 312 is provided with an inclined surface, a No. 1 spring is arranged between the extension rod 305 and the polishing head 306, and a No. 2 spring is arranged between the sliding rod 308 and the fixed disc 304.

[0031] In operation, the mobile plate 314 is pushed to move the support column 301 to the valve port, and then the first motor 302 is started to drive the rotating shaft 303 to rotate, and the rotating shaft 303 drives the telescopic rod 305 to rotate, and the telescopic rod 305 drives the polishing head 306 to rotate.

The rotary plate 510 and the baffle 512 are provided with a No. 5 spring. The water flow in the water tank 505 is sprayed out from the water tank nozzle 511 through the rotation of the valve plate 508. The water is sprayed during polishing to reduce dust, so that the dust and debris are more easily collected under the action of the water flow and are not easily raised due to high-speed polishing, preventing the dust from being raised during high-speed polishing to cause collection difficulty.

When the second U-shaped clamping plate 414 moves downward, the collecting box 501 moves synchronously to wrap the other end of the valve, so that the dust and debris generated during polishing can be collected into the drawer 504 at the bottom of the collecting box 501, ensuring that the dust and debris generated during polishing can be completely collected, preventing the dust and debris from flying and making the cleaning work difficult; when the collecting box 501 moves, the L-shaped push rod 418 gradually approaches, and when it approaches to a certain distance, the L-shaped push rod 418 pushes the push plate 509 to start rotating, the push plate 509 rotates to drive the rotating valve 507 to start rotating, the rotating valve 507 rotates to drive the valve plate 508 to start rotating, and the valve plate 508 rotates to make the water flow in the water tank 505 sprayed from the water tank nozzle 511. When polishing, water is sprayed to reduce dust, so that dust and debris are more easily collected under the action of water flow and are not easily blown up by high-speed polishing, preventing dust from being blown up during high-speed polishing to cause collection difficulties.
