Description

Technical Field

[0001] This utility model relates to the field of metal gasket testing technology, and in particular to a rapid positioning testing stage for multi-size metal gaskets. Background Technology

[0002] Gaskets are mechanical seals between two objects. To ensure product quality, gaskets need to be tested.

[0003] A search revealed a prior art device for testing the flexibility of non-metallic gaskets (publication number: CN118032477A), which includes a testing platform. Arc-shaped plates are movably connected to the four sides of the surface of the testing platform. A triangular slider is fixedly connected to the center of the bottom of the arc-shaped plates. An adhesive pad is provided on the inner wall of the arc-shaped plates. A motor frame is fixedly connected to the bottom of the testing platform, and a drive motor is installed inside the motor frame.

[0004] Existing technologies mainly limit the size of gaskets by mechanical clamping. However, due to the size of the clamping arc plate, the range of gasket sizes that can be limited is very limited. The gasket unloading efficiency is low after clamping and releasing, indicating room for optimization.

[0005] To address this, we propose a rapid positioning and testing stage for multi-size metal gaskets. Utility Model Content

[0006] The present invention aims to solve the technical problems existing in the prior art and provide a rapid positioning and testing stage for multi-size metal gaskets.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: a multi-size rapid positioning and detection stage for metal gaskets, comprising:

[0008] A base, on the top of which a crossbeam is fixedly mounted, and on the bottom of which a camera for detection is fixedly mounted;

[0009] A fixed structure is provided on the top of the base for limiting the gasket. The fixed structure includes an air intake hole, a retaining ring, and a connecting hole. Several air intake holes are opened on the top of the base. Several retaining rings of decreasing size are rotatably connected to the top of the base. Each retaining ring has several connecting holes that correspond one-to-one with the air intake holes. The connecting holes can be aligned with the air intake holes. An air intake structure for drawing air from the air intake holes is provided at the bottom of the base.

[0010] In a preferred embodiment of this utility model, a circular groove is provided on the top of the base, the air intake hole extends through the air intake hole to the bottom of the base, the retaining ring is annular, and multiple air intake holes are sequentially nested together.

[0011] In a preferred embodiment of this utility model, the air intake hole and the inner groove are circular holes of equal diameter, and a ring of connecting holes on each retaining ring corresponds one-to-one with a ring of air intake holes.

[0012] As a preferred embodiment of this utility model, the fixing structure further includes an inner groove, and an inner groove is formed on the upper end face of each retaining ring, the depth of which is less than the thickness of the retaining ring.

[0013] In a preferred embodiment of this utility model, the air intake structure includes an air intake box and a connecting pipe. The air intake box is fixedly installed at the bottom of the base, with an opening at the top and a cavity. The cavity of the air intake box is connected to each air intake hole. The connecting pipe is fixedly connected to the air intake box and is connected to a fan.

[0014] In a preferred embodiment of this utility model, the fixing structure further includes an electric actuator, a guide rod, and a pushing block. The electric actuator is fixedly mounted on the top of the base, and the pushing block is fixedly connected to the output shaft of the electric actuator. The pushing block is limited and slidable by the guide rod.

[0015] In a preferred embodiment of this utility model, a mounting plate is fixedly installed on the top of the base, the electric push rod is fixedly installed on one side of the mounting plate, the guide rod is slidably connected to the mounting plate, and the end of the guide rod and the end of the output shaft of the electric push rod are both fixedly connected to the push block.

[0016] In a preferred embodiment of this utility model, the push block is an arc-shaped plate, and two push blocks are symmetrically arranged on the top of the base. The concave surfaces of the two push blocks are distributed facing each other, and the two push blocks are driven by two electric push rods respectively.

[0017] This invention provides a rapid positioning and testing stage for multi-size metal gaskets. It offers the following advantages:

[0018] 1. This multi-size rapid positioning and testing station for metal gaskets creates negative pressure by drawing air from each suction hole. When the gasket is placed on top of the base, atmospheric pressure presses it down and fixes it on the base for testing. The multiple suction holes arranged in a ring significantly improve the positioning and fixing of gaskets of various sizes, enhancing overall adaptability and applicability. Positioning the gasket simply requires placing it on the base, making operation simple and efficient. To facilitate control over whether the suction holes are in operation, a retaining ring is rotated. When the connecting hole is misaligned with the ring of suction holes below the retaining ring, the retaining ring blocks the ring of suction holes, stopping suction. This allows control over the suction range of the suction holes, adjusting for gasket dimensions and preventing the outer ring of suction holes from affecting loading and unloading. Through the coordinated design of concentric multi-ring negative pressure air paths (3-5 rings independently controllable) and rotating retaining ring type air valves, the gasket can be positioned in seconds, significantly improving efficiency compared to traditional clamps.

[0019] 2. This multi-size rapid positioning and testing stage for metal gaskets uses two electric push rods that move synchronously to push two push blocks closer together. The two push blocks push the gasket placed on the top of the base to the center of the base, ensuring that the gaskets being tested are concentric. The guide rods ensure the stability of the linear sliding of the push blocks, thus ensuring the stability of the entire machine. The rigid synchronous drive of the double arc-shaped push blocks results in low coaxiality error. Combined with laser alignment feedback, it ensures that the center of the gasket is aligned with the camera's line of sight, eliminating measurement errors caused by misalignment.

[0026] A rapid positioning and testing stage for multi-size metal gaskets, such as Figure 1 As shown, it includes:

[0027] A base 10 is provided, with a crossbeam 11 fixedly mounted on the top of the base 10 and a camera 12 for detection fixedly mounted on the bottom of the crossbeam 11.

[0028] A fixed structure is provided on the top of the base 10 for limiting the gasket. The fixed structure includes an air intake hole 20, a retaining ring 21, and a connecting hole 22. Several air intake holes 20 are opened on the top of the base 10. Several retaining rings 21 with decreasing size are rotatably connected to the top of the base 10. Each retaining ring 21 has several connecting holes 22 that correspond one-to-one with the air intake holes 20. The connecting holes 22 can be aligned with the air intake holes 20. An air intake structure for drawing air from the air intake holes 20 is provided at the bottom of the base 10. A circular groove is opened on the top of the base 10. The air intake holes 20 extend through the air intake holes 20 to the bottom of the base 10. The retaining rings 21 are annular. Multiple air intake holes 20 are sequentially nested together. The air intake holes 20 and the inner groove 23 are circular holes with equal diameter. One ring of connecting holes 22 on each retaining ring 21 corresponds one-to-one with one ring of air intake holes 20.

[0029] In this solution, negative pressure is created by drawing air from each suction hole 20. When the gasket is placed on top of the base 10, atmospheric pressure presses the gasket down and fixes it on the base 10 for detection. The multiple suction holes 20 distributed in a ring can significantly improve the limiting and fixing of gaskets of various specifications, improving the overall adaptability and application range. When limiting the gasket, simply place the gasket on the base 10. The operation is simple and efficient. To facilitate the control of whether the ring of suction holes 20 is suctioning, the retaining ring 21 is rotated. When the connecting hole 22 is misaligned with the ring of suction holes 20 below the retaining ring 21, the retaining ring 21 blocks the ring of suction holes 20 and stops suctioning. The suction range of the suction holes 20 can be controlled and adjusted according to the size of the gasket to avoid the ring of suction holes 20 on the outer edge of the gasket affecting loading and unloading. Through the coordinated design of concentric multi-ring negative pressure air circuit (3-5 rings independently controllable) and rotating retaining ring type air valve, the gasket can be positioned in seconds, which is more efficient than traditional clamps.

[0030] The fixing structure also includes an inner groove 23. Each retaining ring 21 has an inner groove 23 on its upper surface. The depth of the inner groove 23 is less than the thickness of the retaining ring 21. By setting the inner groove 23, it is easy to insert and push the retaining ring 21 to rotate by hand, which is easy to operate.

[0031] The air intake structure includes an air intake box 17 and a connecting pipe 18. The air intake box 17 is fixedly installed at the bottom of the base 10. The top of the air intake box 17 is open and has a cavity. The cavity of the air intake box 17 is connected to each air intake hole 20. The connecting pipe 18 is fixedly connected to the air intake box 17 and is connected to a fan. Taking an air intake fan as an example, the connecting pipe 18 is connected to the air inlet of the fan through a pipe to achieve air extraction from the chamber of the air intake box 17. Air is drawn from each air intake hole 20 through the air intake box 17 to form a negative pressure environment. The air path contact surface adopts cavity isolation + fluororubber dynamic sealing.

[0032] The fixed structure also includes an electric actuator 13, a guide rod 14, and a push block 15. The electric actuator 13 is fixedly installed on the top of the base 10. The push block 15 is fixedly connected to the output shaft of the electric actuator 13. The push block 15 is limited and slidable by the guide rod 14. A mounting plate 16 is fixedly installed on the top of the base 10. The electric actuator 13 is fixedly installed on one side of the mounting plate 16. The guide rod 14 is slidably connected to the mounting plate 16. The end of the guide rod 14 and the end of the output shaft of the electric actuator 13 are both fixedly connected to the push block 15. The push block 15 is an arc-shaped plate. Two push blocks 15 are symmetrically arranged on the top of the base 10. The concave surfaces of the two push blocks 15 are distributed facing each other. The two push blocks 15 are driven by two electric actuators 13 respectively.

[0033] In this solution, two electric push rods 13 are connected to the PLC controller. The two electric push rods 13 move synchronously to push two push blocks 15 closer to each other. The two push blocks 15 push the pads on the top of the base 10 to the center of the base 10, ensuring that the pads being detected are concentric. The guide rod 14 can ensure the stability of the linear sliding of the push blocks 15, thus ensuring the stability of the whole machine operation.

[0034] The working principle of this utility model is as follows: An annular sealing groove is formed at the bottom of the retaining ring 21, and a fluororubber O-ring is embedded in the groove. When the retaining ring 21 rotates, the O-ring maintains a compression of 0.2-0.5mm with the top surface of the base 10. A laser displacement sensor (Keyence IL-300) is embedded inside the pushing block 15 to detect the edge distance of the gasket in real time. When the difference in distance between the two sides is >0.1mm, the PLC dynamically adjusts the electric actuator stroke compensation (accuracy ±0.05mm) to ensure the gasket is centered. The connecting pipe 18 is connected to the air inlet of the fan through a pipe to achieve air extraction from the chamber of the suction box 17. Air is drawn from each suction hole 20 through the suction box 17 to form a negative pressure environment. When the gasket is placed on top of the base 10, atmospheric pressure presses the gasket down and fixes it on the base 10 for detection. The multiple suction holes 20 distributed in a ring can greatly improve the detection of multiple gauges. The limiting and fixing of the gasket improves the overall adaptability and application range. By connecting two electric push rods 13 to the PLC controller, the two electric push rods 13 move synchronously to push two push blocks 15 closer to each other. The two push blocks 15 push the gasket placed on the top of the base 10 to the center of the base 10, ensuring that the gaskets being tested are concentric. The camera 12 takes a picture of the gasket, and the target object image is obtained through optical imaging. Then, the measurement, identification or defect judgment is completed by combining algorithm processing and analysis. This will not be elaborated here.
