Description

Technical Field

[0001] This utility model relates to the field of flaw detection equipment, specifically a gasket flaw detection device. Background Technology

[0002] Gaskets are materials placed between two planes to enhance the seal. They are sealing elements placed between static sealing surfaces to support parts or prevent fluid leakage. After the gaskets are manufactured, they need to be sampled for inspection to complete the flaw detection.

[0003] According to a patent document with publication number CN218720024U, a flaw detection anti-deviation mechanism includes a base plate. Two support plates are fixedly connected to the upper surface of the base plate. A mounting plate is fixedly connected to the top of the support plates. A sliding opening is provided on one side of the mounting plate, and a sliding seat is movably connected within the opening. Two guide rods are fixedly connected between the two sliding seats. A movable seat is movably connected to the outer circumference of the guide rods. A probe is fixedly connected to the bottom of the movable seat. A limiting opening is provided on one side of the mounting plate. In use, by installing guide rods on the sliding seats, the movable seat moves along the guide rods, causing the probe to move. During this movement, the guide rods limit the movable seat, thus preventing the probe from deviating during detection. However, while this solution avoids probe deviation, it cannot actively rotate the object during detection, which is inconvenient in use. Utility Model Content

[0007] Furthermore, a switch is fixedly installed on the workbench, and the movable disc is movably installed inside the annular groove via a support mechanism.

[0008] Furthermore, the movable plate has an opening, and a conical column is movably installed inside the opening. A rubber layer is fixed on the surface of the conical column, and a gasket is movably installed between the conical column and the movable plate.

[0009] Furthermore, an output shaft is fixed to the bottom of the tapered column, a drive motor is fixed to one end of the output shaft, a fixing rod is fixedly installed on the drive motor, and the fixing rod is mounted on the support plate.

[0010] Furthermore, the support plate has a fixing groove, one end of the fixing rod is movably installed inside the fixing groove, and the fixing rod is installed inside the fixing groove through a reset mechanism.

[0011] Furthermore, a limiting groove is formed on the inner wall of the fixing groove, and a limiting block is movably installed inside the limiting groove, with one end of the limiting block fixed to the fixing rod.

[0012] Furthermore, a movable column is installed on the lifting mechanism, and a probe is fixed at one end of the movable column. The probe is connected to an ultrasonic generator via an electric wire, and the probe makes movable contact with the pad.

[0013] The beneficial effects of this utility model are:

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] Please see Figures 1 to 5 This utility model provides a technical solution: a gasket flaw detection device, including a workbench 1, a support rod 2 welded to the bottom of the workbench 1, a crossbar 3 welded between the support rods 2, a support plate 4 fixed on the crossbar 3, an annular groove 13 on the workbench 1, a movable disc 14 movably installed inside the annular groove 13, a fixed seat 5 welded to the workbench 1, an ultrasonic generator 6 fixedly installed on the inner wall of the fixed seat 5, a slot 7 on the top of the fixed seat 5, a mounting seat 8 movably installed inside the slot 7, a lifting mechanism 10 fixedly installed on the mounting seat 8, a fixing block 9 welded to the mounting seat 8, a displacement mechanism 11 fixedly installed on the fixing block 9, a protrusion 12 fixed to one end of the displacement mechanism 11, the protrusion 12 fixed to the fixed seat 5, both the lifting mechanism 10 and the displacement mechanism 11 are linear reciprocating electric push rods, the displacement mechanism 11 pushes the lifting mechanism 10 to move and adjust the horizontal position of the probe head 26.

[0025] In this embodiment, a switch 15 is fixedly installed on the workbench 1. The movable disk 14 is movably installed inside the annular groove 13 via a support mechanism 22. An opening 16 is formed on the movable disk 14. A conical column 17 is movably installed inside the opening 16. A rubber layer is fixed on the surface of the conical column 17. A gasket 27 is movably installed between the conical column 17 and the movable disk 14. An output shaft 18 is fixed at the bottom of the conical column 17. A drive motor 19 is fixed at one end of the output shaft 18. A fixing rod 20 is fixedly installed on the drive motor 19. The fixing rod 20 is installed on the support plate 4. The gasket 27 is squeezed and limited on the conical column 17 through the through hole at the center. The rubber layer on the conical column 17 completes the limiting and fixing of the gasket 27 between different positions, which facilitates the rotation detection of the gasket 27 later.

[0026] In this embodiment, the support plate 4 has a fixing groove 23. One end of the fixing rod 20 is movably installed inside the fixing groove 23. The fixing rod 20 is installed inside the fixing groove 23 through a reset mechanism 24. A limit groove is opened on the inner wall of the fixing groove 23. A limit block 21 is movably installed inside the limit groove. One end of the limit block 21 is fixed to the fixing rod 20. A movable column 25 is installed on the lifting mechanism 10. A probe head 26 is fixed to one end of the movable column 25. The probe head 26 is connected to the ultrasonic generator 6 through a wire. The probe head 26 is in movable contact with the gasket 27. Both the support mechanism 22 and the reset mechanism 24 are springs. After the conical column 17 is compressed, the drive motor 19 moves and adjusts on the support plate 4 through the fixing rod 20.

[0027] In use, the device first places the pad 27 on the conical column 17. When placed, the through hole at the center of the pad 27 is installed on the conical column 17. As the pad 27 is pressed, it rubs against the rubber layer and is fixed to the conical column 17. After the pad 27 is fixed in place, the displacement mechanism 11 is activated to adjust the contact position between the probe head 26 and the pad 27. The lifting mechanism 10 is then activated to push the movable column 25 and the probe head 26 to press against the pad 27. Under this pressure, the pad 27 moves downwards, causing the conical column 17 to move downwards. As the conical column 17 moves downwards, it pushes the drive motor 19 downwards via the output shaft 18. After the conical column 17 descends, the pad 27 presses against the movable disc 14, which in turn presses against the support mechanism 22, causing the top of the pad 27 to contact the worktable 1. The tops are aligned in a straight line, effectively preventing misalignment of the pad 27 and the worktable 1 when the probe head 26 contacts the worktable 1, thus avoiding contact problems. During detection, the ultrasonic generator 6 works in conjunction with the probe head 26 to detect the inside of the pad 27. During detection, the displacement mechanism 11 pushes the mounting base 8 to move slowly, and the probe head 26 moves to complete the detection of the radius of the pad 27. When one part of the radius is detected, the probe head 26 rises, and the conical column 17 pushes the pad 27 to separate from the movable plate 14. The drive motor 19 drives the pad 27 to rotate a short distance, changing the detection point after the short rotation. Through reciprocating detection, it is easy to achieve comprehensive and rapid detection of the pad 27. After the pad 27 is detected, the conical column 17 pushes the pad 27 to suspend it, making it easy for the operator to quickly remove the pad 27.
