Description

Technical Field

[0001] This utility model relates to the field of gate valve processing technology, specifically to an auxiliary clamping device for gate valve processing that facilitates spacing adjustment. Background Technology

[0002] Gate valves are an important type of valve, primarily used to control fluid flow. Their main function is to switch fluid flow on and off, typically operating in a fully open or fully closed position. When machining gate valves, the entire process of manufacturing and processing them, including design, material selection, parts machining, assembly, and inspection, requires the assistance of clamping equipment. This equipment is used to fix and support the workpiece during the machining process, its main purpose being to ensure the stability of the gate valve's position during processing.

[0003] Patent CN213702589U discloses a quick-clamping fixture for machining, including an operating box. A positioning seat is fixedly installed at the middle of the top of the outer surface of the operating box. A positioning groove is formed at the middle of the top of the positioning seat. Clamping rods are movably connected to both ends of the top of the outer surface of the operating box via movable pins. An arc-shaped clamping block is fixedly connected to the upper end of one of the two clamping rods that are close to each other. This invention achieves the purpose of quickly clamping and fixing machined parts through the interaction of the positioning seat, positioning groove, motor, first gear, second gear, movable sleeve, threaded rod, lifting plate, movable rod, clamping rods, operating box, and arc-shaped clamping block. The operation is convenient and quick, effectively improving the efficiency of part processing. It solves the problem that most existing clamping fixtures require manual operation by workers, which is cumbersome and reduces machining efficiency.

[0004] Based on existing solutions and actual use, current gate valve machining auxiliary clamping equipment still has some problems. For example, when machining gate valves, the auxiliary clamping cannot adapt to different sizes of gate valves, which also makes it impossible to effectively adjust and lock the workpiece. This causes the workpiece to loosen during the machining process, affecting the machining accuracy and causing product size deviation, thus limiting its application range. Utility Model Content

[0005] The purpose of this utility model is to provide an auxiliary clamping device for gate valve processing that facilitates spacing adjustment, in order to solve the problem mentioned in the background art that when processing gate valves, it is impossible to adapt to gate valves of different sizes, which leads to the inability to effectively adjust and lock the workpiece, resulting in the workpiece loosening during processing, causing product size deviation, and thus limiting the scope of application.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary clamping device for gate valve processing that facilitates spacing adjustment, comprising:

[0007] The base has mounting plates slidably connected to its top left and right ends. Support rods are fixedly mounted on the front and rear ends of the mounting plates, and these support rods are telescopic. Guide rods for pushing are mounted on the support rods. First lead screws are rotatably connected to both ends of the base, and these lead screws are symmetrically arranged about the vertical central axis of the base. A connecting rod is threaded to the outer end of the first lead screw, and the connecting rod is slidably connected to the guide rod. A synchronous pulley is fixedly mounted on the lower end of the first lead screw, and the synchronous pulleys are connected together by a belt sleeve. Two sets of first motors are located at the rear end of the top of the base, and the output ends of the first motors are connected to the first lead screw. A positioning component is mounted on the guide rod.

[0008] Preferably, the base is internally rotatably connected to a bidirectional threaded rod, and the bidirectional threaded rod is threadedly connected to the inner sidewall of the mounting plate, and the bidirectional threaded rod drives the mounting plate to slide in opposite directions.

[0009] Preferably, the guide rod forms a lifting structure with the base via a first lead screw, and the length of the first lead screw body is greater than the length of the inner cavity of the connecting rod.

[0010] Preferably, the positioning component includes a mounting frame, a sliding rod, a claw clamp, a second lead screw, a connecting sleeve, a hinge rod, and a second motor. The mounting frame is fixedly mounted on the connecting rod, and the mounting frame is arranged in a "U" shape. A sliding rod for support is mounted on the mounting frame, and a claw clamp for fixation is slidably connected to the front and rear ends of the sliding rod. A second lead screw is rotatably connected at the middle position of the mounting frame, and a connecting sleeve is mounted on the second lead screw. A hinge rod is rotatably connected to both the front and rear ends of the connecting sleeve. A second motor is fixedly mounted on the mounting frame, and the output end of the second motor is fixedly connected to the body of the second lead screw.

[0011] Preferably, the hinge rod is inclined and rotatably connected to the claw clamp.

[0012] Preferably, the inner wall of the connecting sleeve is connected to the second lead screw by a thread, and the connecting sleeve drives the claw to slide in the opposite direction through the hinge rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are: This gate valve processing auxiliary clamping device with easy spacing adjustment can flexibly handle gate valves of different sizes by adjusting the spacing between the left and right jaws, and can also adapt to gate valves of different lengths and structures by adjusting the spacing between the front and rear jaws. Furthermore, the coordination with the left and right spacing can avoid the risk of movement during processing, thereby meeting diverse processing needs and ensuring the stability of the workpiece during processing, thus improving product accuracy. Moreover, by adjusting the height of the jaws, the height of the equipment can be adjusted according to specific processing needs, thereby increasing the flexibility and versatility of the equipment.

[0014] 1. The device comprises a base, mounting plate, support rod, connecting rod, bidirectional threaded rod, mounting frame, and jaws. The inner wall of the mounting plate is threaded to the bidirectional threaded rod, causing the mounting plate to slide in opposite directions. The support rod is fixedly mounted on the mounting plate, and its guide rod is slidably connected to the connecting rod. When the mounting plate slides on the base, it causes the guide rod to slide on the connecting rod via the support rod. This, in turn, causes the jaws to move closer or further apart via the sliding rod on the mounting frame, adjusting the distance between the left and right jaws. This adjustment allows for flexible handling of gate valves of different sizes and ensures workpiece stability during processing, thereby improving product precision.

[0015] 2. The device is equipped with a guide rod, mounting frame, sliding rod, jaw clamp, second lead screw, connecting sleeve block, hinge rod, and second motor. The output end of the second motor is rotatably connected to the second lead screw, and the inner wall of the connecting sleeve block is threaded to the second lead screw. The hinge rod is also rotatably connected to the connecting sleeve block and jaw clamp in an inclined state. The operation of the second motor drives the connecting sleeve block to slide on the body of the second lead screw. The sliding of the connecting sleeve block, in turn, drives the jaw clamp to slide in the opposite direction on the body of the sliding rod through the hinge rod. This adjusts the distance between the jaw clamps at the front and rear ends of the sliding rod. By adjusting the front and rear distance of the jaw clamps, it can adapt to gate valves of different lengths and structures to meet diverse processing needs. At the same time, the coordination with the left and right distance can avoid the risk of workpiece movement during processing.

[0016] 3. The device is equipped with a support rod, a first lead screw, a connecting rod, a synchronous pulley, a belt, and a first motor. The output of the first motor drives the first lead screw to rotate. The first lead screw is also connected to the inner wall of the connecting rod via a thread. The support rod and the connecting rod are also connected by a guide rod. The support rod is designed to be telescopic. When the first lead screw rotates, it drives the connecting rod to rise and fall. During the rising and falling of the connecting rod, the guide rod drives the support rod to extend and retract synchronously, thereby adjusting the overall height of the jaw clamp. By adjusting the height of the jaw clamp, the height can be adjusted according to specific processing requirements, thereby increasing the flexibility and versatility of the equipment.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-7 This utility model provides a technical solution: an auxiliary clamping device for gate valve processing that facilitates spacing adjustment, comprising: a base 1, a mounting plate 2, a support rod 3, a guide rod 4, a first lead screw 5, a connecting rod 6, a synchronous pulley 7, a belt 8, a first motor 9, a bidirectional threaded rod 10, a mounting frame 11, a sliding rod 12, a claw clamp 13, a second lead screw 14, a connecting sleeve block 15, a hinge rod 16, and a second motor 17.

[0027] First, as attached Figure 1 Appendix Figure 2 Appendix Figure 3 and attached Figure 6 As shown, when processing the gate valve, the height of the jaw clamp 13 is first adjusted according to actual needs. When adjusting the height of the jaw clamp 13, the two sets of first motors 9 at the rear end of the base 1 can be started to run synchronously. Since the left and right ends of the top of the base 1 are slidably connected to the mounting plate 2, and the front and rear ends of the mounting plate 2 are equipped with support rods 3, the left and right ends of the top of the base 1 are rotatably connected to the first lead screw 5. The first lead screw 5 is symmetrically arranged about the vertical central axis of the base 1. The connecting rod 6 is also installed on the outside of the first lead screw 5. Since the support rod 3 is fixedly installed with the guide rod 4, and the guide rod 4 is slidably connected to the connecting rod 6, the output end of the first motor 9 is connected to the first lead screw 5, and the lower end of the first lead screw 9 is connected to the first lead screw 5. A synchronous pulley 7 is fixedly installed on the end rod body, and the synchronous pulleys 7 are connected together by a belt 8. When the two sets of first motors 9 are running, the cooperation between the synchronous pulleys 7 and the belt 8 drives the two sets of first lead screws 5 in the front and rear of the base 1 to rotate synchronously, so that the rotation of the first lead screw 5 drives the connecting rod 6 to form a lifting structure. Since the support rod 3 is set in a telescopic structure, and the support rod 3 and the connecting rod 6 are connected together by a guide rod 4, since the length of the first lead screw 5 is greater than the length of the inner cavity of the connecting rod 6, the lifting of the connecting rod 6 drives the support rod 3 to extend and retract synchronously, so that the height of the jaw 13 can be adjusted according to the actual situation, so that the jaw 13 reaches a suitable height. Adjusting the height of the jaw 13 can adjust the height according to specific processing requirements, increasing the overall flexibility and versatility.

[0028] As attached Figure 1 Appendix Figure 2 Appendix Figure 3 Appendix Figure 4As shown, after the height of the jaw clamp 13 is adjusted according to the actual processing requirements, the bidirectional threaded rod 10 can be rotated. Since the bidirectional threaded rod 10 is connected to the inner wall of the mounting plate 2 by threads, the bidirectional threaded rod 10 drives the mounting plate 2 to slide in opposite directions. When the mounting plate 2 slides on the top of the base 1, the support rod 3 drives the guide rod 4 to move synchronously, and the guide rod 4 slides on the rod body of the connecting rod 6, so that the left and right jaw clamps 13 move closer or further away from each other, thereby adjusting the distance between the jaw clamps 13. The adjustment of the distance between the left and right jaw clamps 13 can flexibly cope with gate valves of different sizes and ensure the stability of the gate valve during the processing.

[0029] As attached Figure 1 Appendix Figure 2 Appendix Figure 3 Appendix Figure 4 Appendix Figure 5 and attached Figure 7 As shown, after adjusting the distance between the left and right sets of claws 13, the second motor 17 can be started. Since a mounting frame 11 is fixedly installed on the guide rod 4, and the mounting frame 11 is arranged in a "U" shape, a sliding rod 12 is installed on the frame of the mounting frame 11. The claws 13 are slidably connected to the front and rear ends of the sliding rod 12. A second lead screw 14 is rotatably connected to the frame of the mounting frame 11. Since the second lead screw 14 is connected to the output end of the second motor 17, the operation of the second motor 17 can drive the second lead screw 14 to rotate. The inner wall of the connecting sleeve 15 is connected to the second lead screw 14 by threads, and both the front and rear ends of the connecting sleeve 15 are rotatably connected. A hinge rod 16 is connected, and then the hinge rod 16 is rotatably connected to the jaw clamp 13 in an inclined state. When the second lead screw 14 rotates, it drives the connecting sleeve block 15 to slide. The sliding of the connecting sleeve block 15 can drive the jaw clamp 13 to slide on the body of the sliding rod 12 through the hinge rod 16, and make the jaw clamps 13 at the front and rear ends of the sliding rod 12 slide in opposite directions. This makes the jaw clamps 13 at the front and rear ends of the sliding rod 12 move closer or further apart, so as to adjust the distance between the front and rear jaw clamps 13. This allows it to adapt to gate valves of different lengths and structures and meet diverse processing needs. The coordination of the adjustment of the distance between the left and right jaw clamps 13 can avoid the risk of workpiece movement during processing.
