[0005] Aiming at the deficiencies of the prior art, the present invention provides a grinding device for valve production, which solves the problems raised in the above background art.

[0006] To achieve the above objectives, the present invention is realized through the following technical solutions: A grinding device for valve production includes a base, support feet fixedly installed at the bottom of the base, a jet grinding device disposed on the top of the base, a clamping device disposed on the top of the base, and a collection device disposed on the top of the base; Among them, the jet grinding device includes a support column, a first motor, a rotating shaft, a fixed disk, a telescopic rod, a grinding head, a push block, a sliding rod, a vertical rod, a cylinder, a cylinder push plate, a cylinder push rod, a jet pipe and a moving plate. The support column is slidably installed on the top of the base. The first motor is fixedly installed at the rear of the support column. The rotating shaft is fixedly installed at the output end of the first motor. The fixed disk is fixedly installed at the front of the support column. The telescopic rod is fixedly installed at the end of the rotating shaft away from the first motor. The grinding head is fixedly installed at the end of the telescopic rod away from the rotating shaft. The push block is fixedly installed on the circumferential surface of the telescopic rod. The sliding rod slidably penetrates the fixed disk. The vertical rod is slidably installed at the rear of the fixed disk. The cylinder is fixedly installed at the rear of the fixed disk.

The jet pipe is fixedly installed at the front of the cylinder. The moving plate is fixedly installed at the front of the support column. The rotation of the telescopic rod drives the grinding head to start rotating. As the rotation speed of the rotating shaft increases, the telescopic rod gradually extends under the action of centrifugal force, so that the grinding head closely adheres to the inner wall of the valve during grinding, and the inner wall of the valve is ground clean and flat, so as to prevent the grinding effect from being greatly reduced due to the fact that the grinding head cannot closely adhere to the inner wall of the valve, resulting in the valve not being able to closely adhere to the pipe wall during subsequent docking.

[0007] According to the above technical solution, the surface of the push block in contact with the sliding rod is set as an inclined surface, the surface of the sliding rod in contact with the vertical rod is set as an inclined surface, the surface of the vertical rod in contact with the cylinder push rod is set as an inclined surface. A first spring is provided between the telescopic rod and the grinding head, and a second spring is provided between the sliding rod and the fixed disk. By moving the cylinder push plate, the gas in the cylinder is pushed out from the jet pipe, so that during grinding, the dust and debris ground off can be blown forward by the continuous jet of the cylinder, and the inner wall of the valve is cleaned, so as to prevent the dust and debris ground off from remaining on the inner wall of the valve and affecting the subsequent processing or use of the valve if not cleaned in time.

[0008] According to the above technical solution, the clamping device includes a bracket, a second motor, a first threaded rod, a first U-shaped clamping plate, a first hydraulic cylinder, a first hydraulic push plate, a first hydraulic push rod, a second hydraulic cylinder, a second hydraulic push plate, a second hydraulic push rod, a hydraulic pipe, and a first clamping plate. The bracket is fixedly installed on the top of the base. The second motor is fixedly installed on the top of the bracket. The first threaded rod is fixedly installed at the output end of the second motor. The first U-shaped clamping plate is fixedly installed on the top of the base. The first hydraulic cylinder is fixedly installed on the left side of the first U-shaped clamping plate. The first hydraulic push plate is slidably installed inside the first hydraulic cylinder. The first hydraulic push rod is fixedly installed on the top of the first hydraulic push plate. The second hydraulic cylinder is fixedly installed on the top of the base. The second hydraulic push plate is slidably installed inside the second hydraulic cylinder. The second hydraulic push rod is fixedly installed on the top of the second hydraulic push plate. The first hydraulic cylinder and the second hydraulic cylinder are connected through a hydraulic pipe. The first clamping plate is fixedly installed on the top of the second hydraulic push rod. 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 it down to turn off the second motor, so 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 each other, and will not continue to clamp after contact, causing damage to the second U-shaped clamping plate and the first U-shaped clamping plate, so as to prevent damage to the second U-shaped clamping plate and the first U-shaped clamping plate caused by the second motor not turning off and continuing to clamp.

[0009] According to the above technical solution, the clamping device further includes a sleeve, a second U-shaped clamping plate, a T-shaped pressure rod, a second clamping plate, a second motor switch, an L-shaped push rod, and a first gear. The sleeve is slidably installed on the circumferential surface of the first threaded rod. The second U-shaped clamping plate is fixedly installed on the circumferential surface of the sleeve. The T-shaped pressure rod slidably penetrates the bracket and the second U-shaped clamping plate. The second clamping plate is fixedly installed at the bottom of the T-shaped pressure rod. The second motor switch is fixedly installed on the top of the second motor. The L-shaped push rod is fixedly installed at the front of the bracket. The first gear is fixedly installed on the circumferential surface of the first threaded rod. 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 it down to turn off the second motor, so 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 each other, and will not continue to clamp after contact, causing damage to the second U-shaped clamping plate and the first U-shaped clamping plate.

[0010] According to the above technical solution, the first threaded rod is threadedly connected to the sleeve. A third spring is provided between the second hydraulic push plate and the second hydraulic cylinder. A fourth spring is provided between the second U-shaped clamping plate and the second clamping plate. The valve is squeezed and clamped by the upward movement of the first clamping plate, ensuring that the valve will not vibrate excessively during grinding, so as to prevent mistakes in grinding and a reduction in the grinding effect caused by excessive vibration during grinding.

[0011] According to the above technical solution, the collection device includes a collection box, a second threaded rod, a second gear, a drawer, a water tank, and a fan-shaped conduit. The collection box is slidably mounted on the top of the base. The second threaded rod is rotatably mounted on the left side of the collection box. The second gear is fixedly mounted on the circumferential surface of the second threaded rod close to the first threaded rod. The drawer is slidably mounted on the bottom of the collection box. The water tank is fixedly mounted on the top of the collection box. The fan-shaped conduit is fixedly mounted on the bottom of the water tank. When the second U-shaped clamp moves downward, the collection box moves synchronously to wrap the other end of the valve, so that during grinding, the dust and debris ground off can be collected into the drawer at the bottom of the collection box, ensuring that all the ground dust and debris can be completely collected, so as to prevent the dust and debris from splashing due to failure to collect them in time during grinding, making the cleaning work difficult to carry out.

[0012] According to the above technical solution, the collection device further includes a rotary valve, a valve plate, a push plate, a rotary plate, a water tank spray head, and a baffle. The rotary valve is rotatably mounted on the top of the collection box. The valve plate is fixedly mounted on the inner wall of the rotary valve. The push plate is fixedly mounted on the circumferential surface of the rotary valve. The rotary plate is fixedly mounted on the circumferential surface of the rotary valve. The water tank spray head is fixedly mounted on the top inner wall of the collection box. The baffle is fixedly mounted on the top of the collection box. When the second U-shaped clamp moves downward, the collection box moves synchronously to wrap the other end of the valve, so that during grinding, the dust and debris ground off can be collected into the drawer at the bottom of the collection box, ensuring that all the ground dust and debris can be completely collected.

[0013] According to the above technical solution, the second threaded rod is threadedly connected to the collection box. The first gear meshes with the second gear. A fifth spring is provided between the rotary plate and the baffle. By rotating the valve plate, the water flow in the water tank is sprayed out from the water tank spray head, spraying water to reduce dust during grinding, so that the dust and debris are more easily collected under the action of the water flow, and dust will not be raised due to high-speed grinding, so as to prevent dust from being raised during high-speed grinding, causing difficulties in collection.

[0014] The present invention provides a grinding device for valve production. It has the following beneficial effects: (1) In this invention, the rotation of the telescopic rod drives the grinding head to start rotating. As the rotation speed of the rotating shaft increases, the telescopic rod gradually extends under the action of centrifugal force, so that the grinding head closely adheres to the inner wall of the valve during grinding, grinding the inner wall of the valve clean and flat, so as to prevent the grinding head from not closely adhering to the inner wall of the valve, resulting in a greatly reduced grinding effect, and causing the valve not to closely adhere to the pipe wall during subsequent docking. By moving the push plate of the air cylinder, the gas in the air cylinder is pushed out from the air injection pipe, so that during grinding, the dust and debris ground off can be blown forward and away from the inner wall of the valve by continuously jetting air from the air cylinder, cleaning the inner wall of the valve, so as to prevent the dust and debris ground off from remaining on the inner wall of the valve without being cleaned in time, affecting the subsequent processing or use of the valve.

[0015] (2) In this invention, when the second U-shaped clamping plate descends to contact the first U-shaped clamping plate, the T-shaped pressing rod touches the switch of the second motor and presses it down to turn off the second motor, so that the second motor is turned off in time after the second U-shaped clamping plate and the first U-shaped clamping plate contact and clamp each other, and will not continue to clamp after contact, causing damage to the second U-shaped clamping plate and the first U-shaped clamping plate, preventing damage to the second U-shaped clamping plate and the first U-shaped clamping plate due to the continuous clamping caused by the failure to turn off the second motor. The first clamping plate starts to move upward by the upward movement of the second hydraulic push rod, and the first clamping plate moves upward to squeeze and clamp the valve, ensuring that the valve will not vibrate excessively during grinding, preventing mistakes in grinding and reducing the grinding effect caused by excessive vibration during grinding.

[0016] (3) In this invention, when the second U-shaped clamping plate moves downward, the collection box moves synchronously to wrap the other end of the valve, so that the dust and debris generated during grinding can be collected into the drawer at the bottom of the collection box, ensuring that all the dust and debris generated during grinding can be completely collected, preventing the dust and debris from splashing during grinding due to the failure to collect them in time, making it difficult to carry out the cleaning work. The water in the water tank is sprayed out from the water tank nozzle by the rotation of the valve plate, spraying water to reduce dust during grinding, making the dust and debris easier to collect under the action of the water flow, and preventing the dust from being raised during high-speed grinding, causing difficulties in collection.

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.

[0020] Please refer to Figures 1 - 7 , an embodiment of the present invention is: A grinding device for valve production, including a base 1, support feet 2 are fixedly installed at the bottom of the base 1, and a jet grinding device is arranged on the top of the base 1; Among them, the jet polishing device includes a support column 301, a first motor 302, a rotating shaft 303, a fixed disk 304, a telescopic rod 305, a polishing head 306, a push block 307, a sliding rod 308, a vertical rod 309, a cylinder 310, a cylinder push plate 311, a cylinder push rod 312, a jet pipe 313 and a moving plate 314. The support column 301 is slidably installed on the top of the base 1. The first motor 302 is fixedly installed at the rear of the support column 301. The rotating shaft 303 is fixedly installed at the output end of the first motor 302. The fixed disk 304 is fixedly installed at the front of the support column 301. The telescopic rod 305 is fixedly installed at the end of the rotating shaft 303 away from the first motor 302. The polishing head 306 is fixedly installed at the end of the telescopic rod 305 away from the rotating shaft 303. The push block 307 is fixedly installed on the circumferential surface of the telescopic rod 305. The sliding rod 308 slidably penetrates through the fixed disk 304. The vertical rod 309 is slidably installed at the rear of the fixed disk 304. The cylinder 310 is fixedly installed at the rear of the fixed disk 304. The cylinder push plate 311 is slidably installed on the inner wall of the cylinder 310. The cylinder push rod 312 is fixedly installed at the rear of the cylinder push plate 311. The jet pipe 313 is fixedly installed at the front of the cylinder 310. The moving plate 314 is fixedly installed at the front of the support column 301. By driving the rotation of the telescopic rod 305, the polishing head 306 starts to rotate. As the rotation speed of the rotating shaft 303 increases, the telescopic rod 305 gradually extends under the action of centrifugal force, 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 effect from being greatly reduced due to the fact that the polishing head 306 cannot closely adhere to the inner wall of the valve, resulting in the valve not being able to closely adhere to the pipe wall during subsequent docking.

[0021] One side of the push block 307 in contact with the sliding rod 308 is set as an inclined surface. One side of the sliding rod 308 in contact with the vertical rod 309 is set as an inclined surface. One side of the vertical rod 309 in contact with the cylinder push rod 312 is set as an inclined surface. A first spring is provided between the telescopic rod 305 and the polishing head 306. A second spring is provided between the sliding rod 308 and the fixed disk 304. By moving the cylinder push plate 311, the gas in the cylinder is pushed out from the jet pipe 313, so that during polishing, the dust and debris polished off can be blown forward away from the jet of the cylinder 310 continuously, and the inner wall of the valve is cleaned, so as to prevent the dust and debris polished off from remaining on the inner wall of the valve without timely cleaning and affecting the subsequent processing or use of the valve.

[0022] During the operation of this embodiment: Push the moving plate 314 to drive the support column 301 to move, move the support column 301 to the valve opening, and then start the first motor 302 to drive the rotating shaft 303 to start rotating. The rotation of the rotating shaft 303 drives the telescopic rod 305 to start rotating, and the rotation of the telescopic rod 305 drives the grinding head 306 to start rotating. As the rotation speed of the rotating shaft 303 increases, the telescopic rod 305 gradually extends under the action of centrifugal force, so that the grinding head 306 closely adheres to the inner wall of the valve during grinding, and the inner wall of the valve is ground clean and flat, so as to prevent the grinding effect from being greatly reduced due to the inability of the grinding head 306 to closely adhere to the inner wall of the valve, resulting in the inability of the valve to closely adhere to the pipe wall during subsequent docking; The telescopic rod 305 drives the push block 307 to rotate during rotation. When the push block 307 rotates, it pushes the sliding rod 308 to start moving. The movement of the sliding rod 308 pushes the vertical rod 309 to start moving upward. The upward movement of the vertical rod 309 pushes the cylinder push rod 312 to start moving. The movement of the cylinder push rod 312 pushes the cylinder push plate 311 to start moving. The movement of the cylinder push plate 311 pushes the gas in the cylinder to spray out from the air injection pipe 313, so that during grinding, the dust and debris ground off can be blown forward by the continuous air injection of the cylinder 310, and the inner wall of the valve is cleaned, so as to prevent the dust and debris ground off from remaining on the inner wall of the valve without timely cleaning, affecting the subsequent processing or use of the valve.

[0025] The first threaded rod 403 is threadedly connected to the sleeve 413. A third spring is provided between the second hydraulic push plate 409 and the second hydraulic cylinder 408. A fourth spring is provided between the second U-shaped clamping plate 414 and the second clamping plate 416. The valve is squeezed and clamped by the upward movement of the first clamping plate 412 to ensure that the valve will not vibrate excessively during grinding, so as to prevent mistakes in grinding caused by excessive vibration during grinding and reduce the grinding effect.

The sector-shaped conduit 506 is fixedly mounted at the bottom of the water tank 505. When the second U-shaped clamping plate 414 moves downward, the collection box 501 moves synchronously to wrap the other end of the valve, so that the dust and debris generated during grinding can be collected into the drawer 504 at the bottom of the collection box 501, ensuring that all the dust and debris ground off can be completely collected, so as to prevent the dust and debris from splashing due to failure to collect them in time during grinding, making the cleaning work difficult to carry out.

[0027] The collection device further includes a rotary valve 507, a valve plate 508, a push plate 509, a rotary plate 510, a water tank nozzle 511 and a baffle 512.

A fifth spring is provided between the rotary plate 510 and the baffle 512. When the valve plate 508 rotates, the water flow in the water tank 505 sprays out from the water tank nozzle 511, spraying water to reduce dust during grinding, making it easier to collect dust and debris under the action of the water flow, and preventing dust from being raised during high-speed grinding, so as to avoid difficulties in collection caused by the raising of dust during high-speed grinding.

[0029] During the operation of this embodiment: Place the valve to be polished on the inner wall of the first U-shaped clamping plate 404. Then, start the second motor 402 to drive the first threaded rod 403 to rotate. The rotation of the first threaded rod 403 drives the sleeve 413 to move downward. The downward movement of the sleeve 413 drives the second U-shaped clamping plate 414 to move downward. The downward movement of the second U-shaped clamping plate 414 drives the second clamping plate 416 to move downward. The downward movement of the second clamping plate 416 drives the T-shaped pressure rod 415 to move downward. When the second U-shaped clamping plate 414 descends to contact the first U-shaped clamping plate 404, the T-shaped pressure rod 415 touches the second motor switch 417 and presses it down to turn off the second motor 402, so that the second motor 402 is turned off in time after the second U-shaped clamping plate 414 and the first U-shaped clamping plate 404 are in contact and clamped, and will not continue to clamp after contact, causing damage to the second U-shaped clamping plate 414 and the first U-shaped clamping plate 404, to prevent damage to the second U-shaped clamping plate 414 and the first U-shaped clamping plate 404 caused by the continuous clamping due to the non-turning off of the second motor 402; When the second U-shaped clamping plate 414 moves downward to press the first hydraulic push rod 407 to move downward, the downward movement of the first hydraulic push rod 407 pushes the first hydraulic push plate 406 to move downward. The downward movement of the first hydraulic push plate 406 squeezes the liquid in the first hydraulic cylinder through the hydraulic pipe 411 and flows to the second hydraulic cylinder 408, squeezing the second hydraulic push plate 409 to make the second hydraulic push plate 409 move upward. The upward movement of the second hydraulic push plate 409 pushes the second hydraulic push rod 410 to move upward. The upward movement of the second hydraulic push rod 410 pushes the first clamping plate 412 to move upward. The upward movement of the first clamping plate 412 squeezes and clamps the valve to ensure that the valve will not vibrate excessively during polishing, to prevent mistakes in polishing and a reduction in the polishing effect caused by excessive vibration during polishing.

[0030] When the second U-shaped clamp plate 414 moves downward, the first threaded rod 403 rotates to drive the first gear 419 to start rotating. The rotation of the first gear 419 drives the second gear 503 to start rotating. The rotation of the second gear 503 drives the second threaded rod 502 to start rotating. The rotation of the second threaded rod 502 drives the collection box 501 to start moving. When the second U-shaped clamp plate 414 moves downward, the collection box 501 moves synchronously to wrap the other end of the valve, so that during grinding, the dust and debris ground off can be collected into the drawer 504 at the bottom of the collection box 501, ensuring that all the ground dust and debris can be completely collected to prevent the dust and debris from splashing during grinding due to failure to collect them in time, making the cleaning work difficult to carry out. When the collection box 501 moves, the L-shaped push rod 418 gradually approaches. When it approaches to a certain distance, the L-shaped push rod 418 pushes the push plate 509 to start rotating. The rotation of the push plate 509 drives the rotary valve 507 to start rotating. The rotation of the rotary valve 507 drives the valve plate 508 to start rotating. The rotation of the valve plate 508 causes the water in the water tank 505 to spray out from the water tank nozzle 511, spraying water to reduce dust during grinding, making the dust and debris easier to collect under the action of the water flow and preventing the dust from being raised during high-speed grinding, thus preventing the dust from being raised during high-speed grinding and causing difficulties in collection.
