[0002] Valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. Valves are also divided into cast iron valves, cast steel valves, stainless steel valves, chrome-molybdenum steel valves, chrome-molybdenum-vanadium steel valves, duplex steel valves, plastic valves and non-standard customized valves according to their materials. The connections on the valves are mostly made with bolts and flanges. Valves need to be fixed with special positioning devices during production and processing.

[0003] The existing positioning devices currently cannot adjust the positioning position according to the actual size of the valve, which limits the overall use range of the positioning devices and the overall flexibility is not high. In addition, the existing positioning devices are difficult to turn when processing the valve, resulting in the need to disassemble the valve when processing the bottom side of the valve, and then flip it over before it can be re-fixed, which is very troublesome to operate. Therefore, a valve processing positioning device is proposed to solve the above problems. Utility Model Content

The rotation limit assembly includes a turntable 14 fixedly installed on the other end of the rotating rod 13, and two rotating rods 15 are fixedly installed on the outer side of the turntable 14. The turntable 14 and the second fixed plate 11 are respectively provided with a plurality of threaded holes and threaded grooves, and the plurality of threaded holes and the plurality of threaded grooves are adapted to each other, and the plurality of threaded holes A limit rod 16 is threadedly installed in one of the threaded holes, and the other end of the limit rod 16 is threadedly installed in a thread groove aligned with one of the threaded holes. When the bottom side of the valve needs to be processed, the turntable 14 can be driven to rotate by manually rotating the turn rod 15. When the turntable 14 rotates, the mounting plate 19 on one side of the first fixed plate 10 can be driven to rotate. Because the same valve is clamped between the two mounting plates 19 by the clamping assembly, when one mounting plate 19 is rotated, the other mounting plate 19 will also rotate synchronously, and a round shaft 18 is provided on one side of the other mounting plate 19. Therefore, the valve can be flipped under the action of the circular shaft 18, and the valve can be flipped without disassembling the clamping assembly. After the flipping is completed, if processing is required, one end of the limit rod 16 is threaded into one of the threaded holes, and then the other end of the limit rod 16 is threaded into the threaded groove aligned with the threaded hole, thereby realizing a fixed connection between the second fixed plate 11 and the turntable 14, and also avoiding the situation that the valve will rotate during processing, and the two limit rings 17 are set to prevent the rotating rod 13 from being offset.

[0022] Specifically, the clamping assembly includes two mounting plates 19 on which a placing plate 20 is fixedly installed on one side close to each other, and the two placing plates 20 are both arranged in an arc shape. A side plate 21 is fixedly installed on one side close to each other of the two mounting plates 19, and electric push rods 22 are fixedly installed on the top sides of the two side plates 21. The output ends of the two electric push rods 22 pass through the side plates 21 and are fixedly connected with clamping plates 23. The two clamping plates 23 face the placing plates 20, and the two placing plates 20 are on the same horizontal line. By placing the two ends of the valve on the two placing plates 20 respectively, and starting the two electric push rods 22 synchronously after the two ends are placed, the operation of the two electric push rods 22 can drive the two clamping plates 23 to move toward the two placing plates 20 respectively, and then the clamping of the two ends of the valve can be completed, and valves of different sizes can also be clamped.

[0023] Specifically, the adjustment component includes a threaded motor 4 fixedly mounted on one side of the base plate 1, the output end of the threaded motor 4 rotates through the base plate 1 and is fixedly mounted with a bidirectional screw 5, the other end of the bidirectional screw 5 is rotatably connected to the inner wall of one side of the long groove, the outer side of the bidirectional screw 5 is slidably mounted with a first slider 6 and a second slider 7, the top sides of the first slider 6 and the second slider 7 are fixedly mounted with a top plate 8, the first fixed plate 10 and the second fixed plate 11 are respectively fixedly mounted on the top sides of the two top plates 8, two guide blocks 9 are fixedly mounted on the bottom sides of the two top plates 8, two guide grooves 3 are opened on the top side of the base plate 1, the two guide grooves 3 are adapted to a plurality of guide blocks 9, and the plurality of guide blocks 9 are respectively slidably mounted on the two guide grooves. In the groove 3, when it is necessary to position a valve with a longer size, the bidirectional screw 5 is driven to rotate by starting the threaded motor 4, so that the first slider 6 and the second slider 7 are moved away from each other, so that the larger valve can be clamped, and the distance between the first slider 6 and the second slider 7 can be adjusted according to valves of different lengths, so that valves of different lengths can be processed, and the valve can be flipped without disassembling the clamping assembly, thereby speeding up the processing speed of the valve. By setting a plurality of guide blocks 9, when the first slider 6 and the second slider 7 are close to or away from each other, the plurality of guide blocks 9 can slide in the two guide grooves 3, and can play a guiding role when moving.

[0024] The valve processing and positioning device is connected to 220V mains electricity, and the main controller can be a conventional known device for control such as a computer.

[0025] During use: when the valve needs to be processed, it is necessary to use a positioning device to fix it. At this time, the two ends of the valve are placed on the two placement plates 20 respectively. After the two ends are placed, the two electric push rods 22 are started synchronously. The operation of the two electric push rods 22 can drive the two clamping plates 23 to move toward the two placement plates 20 respectively, and then the clamping of the two ends of the valve can be completed. After the clamping is completed, the personnel can process the valve. When the bottom side of the valve needs to be inspected or processed, the turntable 14 can be driven to rotate by manually rotating the rotating rod 15. When the turntable 14 rotates, the mounting plate 19 on one side of the first fixed plate 10 can be driven to rotate. Because the two mounting plates 19 clamp the same valve through the clamping assembly, when one mounting plate 19 is rotated, the other mounting plate 19 will also rotate synchronously. A round shaft 18 is provided on one side of the other mounting plate 19, so the valve can be flipped under the action of the round shaft 18, and there is no need to The valve can also be flipped by removing the clamping assembly. After the flipping is completed, if processing is required, one end of the limit rod 16 is threaded into one of the threaded holes, and then the other end of the limit rod 16 is threaded into the threaded groove aligned with the threaded hole, so as to achieve a fixed connection between the second fixed plate 11 and the turntable 14, and also avoid the situation that the valve will rotate during processing. The two limit rings 17 are set, and the rotating rod 13 will not be offset. When it is necessary to position a longer valve, the bidirectional screw 5 is driven to rotate by starting the threaded motor 4, so that the first slider 6 and the second slider 7 are moved away from each other, so that the larger valve can be clamped, and the distance between the first slider 6 and the second slider 7 can be adjusted according to valves of different lengths, so that valves of different lengths can be processed, and the valve can be flipped without disassembling the clamping assembly, thereby speeding up the processing of the valve.
