Description

Technical Field

[0001] The utility model relates to the field of valve production, in particular to a clamping device for valve production and detection. Background Technique

[0002] A clamping device for valve production and detection is a device specifically used for detection and testing during the valve production process. The main function of this device is to ensure that the valve can be stably clamped under various test conditions for necessary performance testing and quality control.

[0003] Traditional clamping devices may require manual operation, increasing the operation time and labor intensity. For valves of different sizes, traditional clamping devices may require replacing the fixture, which is both time-consuming and laborious. It may not be convenient for quick positioning and clamping, resulting in low production efficiency. At the same time, it may not be very adaptable to valves of different sizes and requires frequent fixture replacement, which not only wastes time but also increases production costs.

[0004] Therefore, those skilled in the art have provided a clamping device for valve production and detection to solve the problems raised in the above background technique. Content of the Utility Model

[0005] The purpose of the content of the utility model is to solve the shortcomings existing in the prior art, and a clamping device for valve production and detection is proposed. The operation control panel enables the cylinder to drive the second connecting plate to slide on the sliding seat on one side along the sliding rod. The sliding seat on one side simultaneously drives the first connecting plate to slide. Through the sliding connection of the gear with the first rack and the second rack, finally, after reaching a certain distance, the valve can be stably clamped through the cooperation of the first clamping grooves and the second clamping grooves on both sides.

[0006] To achieve the above purpose, the utility model provides the following technical solution:

[0007] A clamping device for valve production and detection includes a clamping mechanism and an adjusting mechanism. The clamping mechanism includes a fixed seat and a gear. One side of the upper end of the fixed seat is fixedly connected with a fixing plate. The middle part of one side of the fixing plate is provided with a control panel. The middle part of the other side of the fixing plate is fixedly connected with a cylinder. The output end of the cylinder is fixedly connected with a second connecting plate. A first sliding groove is opened on the other side of the upper end of the fixed seat. Both sides of the lower end of the fixed seat are fixedly connected with support plates. The front end and the rear end of the lower surface of the support plate are fixedly connected with first fixing blocks. The inner walls of the first fixing blocks are all slidably connected with sliding rods;

[0008] Sliding seats are slidably connected to both sides of the outer walls of the two sliding rods. The upper ends of the sliding seats on the other side are fixedly connected to the lower end of the second connecting plate. The middle parts of the lower ends of the sliding seats are fixedly connected with first connecting plates. The front end of the upper part of one first connecting plate is fixedly connected with a second fixing block. The rear end of the upper part of one first connecting plate and the front end of the upper part of the first connecting plate on the other side are both fixedly connected with third fixing blocks. The rear end of the upper part of the first connecting plate on the other side and the front end of the upper part of one first connecting plate are both fixedly connected with second fixing blocks. The rear end of the gear meshes with a first rack, and the outer wall of the first rack is slidably connected to the inner wall of the second chute at the rear end of one side. The front end of the gear meshes with a second rack, and the outer wall of the second rack is slidably connected to the inner wall of the second chute. The outer wall of the other side of the first rack is fixedly connected to the third fixing block at the rear end of the other side. The outer wall of one side of the second rack is fixedly connected to the third fixing block on one side. The lower ends of the first connecting plates are all fixedly connected with adjusting mechanisms.

[0009] Through the above technical solution, the operator first turns on the control panel, which causes the cylinder to move. The output end of the cylinder drives the second connecting plate to slide back and forth inside the first chute. The second connecting plate will drive the sliding seats on the other side to slide on the sliding rods. The sliding seats on one side will simultaneously drive the first connecting plates to slide. Through the sliding connection between the gear and the first rack and the second rack, the third fixing blocks fixedly connected to the first connecting plates drive the second rack to slide on the inner wall of the second chute on the other side. At the same time, the third fixing blocks on the other side drive the first rack to slide on the inner wall of the second chute on one side. Finally, after reaching a certain distance, the valve can be stably clamped through the cooperation of the first clamping grooves and the second clamping grooves on both sides.

[0010] Furthermore, the adjusting mechanism includes a third connecting plate. Third chutes are respectively opened on one side of the third connecting plate close to the center of the gear. The front ends of the inner walls of the third chutes are fixedly connected with servo motors. The output ends of the servo motors are fixedly connected with bidirectional threaded rods. Sliders are sleeved on both ends of the rod body of the bidirectional threaded rod. The sliders are fixedly connected with connecting rods on the sides far away from the third connecting plate. The connecting rods on one side are fixedly connected with second clamping grooves on the sides far away from the third connecting plate. The connecting rods on the other side are fixedly connected with first clamping grooves on the sides far away from the third connecting plate.

[0011] Through the above technical solution, by turning on the control panel, the control panel drives the servo motors on both sides to move simultaneously. The servo motors drive the bidirectional threaded rods to rotate. The sliders at both ends of the rod body of the bidirectional threaded rod will slide back and forth. At this time, the sliders will drive the first clamping grooves and the second clamping grooves to slide through the connecting rods. The distance between the first clamping grooves and the second clamping grooves on both sides can be adjusted according to the different sizes of the valves, so as to clamp valves of different sizes, meeting the requirement of not needing to replace the fixture and saving the time for replacing the fixture.

[0012] Furthermore, the outer wall of the second connecting plate slides inside the first sliding groove;

[0013] Through the above technical solution, it can move freely within a certain range to adapt to valves at different positions.

[0014] Furthermore, second sliding grooves are provided on one sides of the second fixing blocks close to the center of the fixing seat;

[0015] Through the above technical solution, the clamping device can adapt to valves of different sizes and shapes. The design of the second sliding groove enables the operator to conveniently adjust the position of the second fixing block, improving the operation efficiency.

[0016] Furthermore, one ends of the bidirectional threaded rods far from the servo motor are rotatably connected to the rear ends of the inner walls of the third sliding grooves;

[0017] Through the above technical solution, precise motion control is achieved through screw drive. One end of the bidirectional threaded rod is connected to the servo motor, and the other end is rotatably connected to the inner wall of the third sliding groove. This design can convert the rotational motion of the bidirectional threaded rod into linear motion.

[0018] Furthermore, a connecting column is rotatably connected to the upper end of the gear, and the upper end of the connecting column is fixedly connected to the middle of the lower end of the fixing seat;

[0019] Through the above technical solution, the fixed connection between the connecting column and the fixing seat can bear the dynamic loads that the clamping device may encounter during operation. By ensuring the firmness of the connection, the safety of the clamping device is improved, especially when dealing with heavy or fragile valves.

[0020] Furthermore, the outer wall on the other side of the first rack is fixedly connected to the third fixing block at the rear end on the other side, and the outer wall on one side of the second rack is fixedly connected to the third fixing block on one side;

[0021] Through the above technical solution, stable support is provided for the racks to prevent accidental movement during operation. The fixed connection between the second rack and the third fixing block ensures the effective transmission of force, which is very important for the stability and reliability of the clamping device. The design of the fixed connection makes the maintenance and adjustment of the first rack and the second rack relatively easy, and can be conveniently operated if replacement or repair is required.

[0022] Furthermore, the outer wall on the other side of the first rack is fixedly connected to the third fixing block at the rear end on the other side, and the outer wall on one side of the second rack is fixedly connected to the third fixing block on one side;
