Description

Technical Field

[0001] This utility model relates to the field of fluorescent magnetic particle flaw detectors, and in particular to a fluorescent magnetic particle flaw detector for car couplers. Background Technology

[0002] A fluorescent magnetic particle testing machine is a device used for detecting defects on metal surfaces. It is commonly used to inspect surface and near-surface defects in metallic materials, such as cracks, pores, and inclusions, and is particularly widely used in ferromagnetic materials. Combining magnetic particle testing technology with fluorescent detection technology, it can efficiently and accurately detect minute surface defects. Fluorescent magnetic particle testing machines are often chosen for flaw detection of high-strength, high-stability car couplers.

[0003] The existing fluorescent magnetic particle flaw detectors require manual rotation of the coupler workpiece 360 ​​degrees to spray fluorescent magnetic powder liquid from all directions. This not only consumes manpower, but the fluorescent magnetic powder liquid can also cause certain harm to the operator's body during the spraying process.

[0004] Therefore, we propose a fluorescent magnetic particle flaw detector for couplers to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a fluorescent magnetic particle flaw detector for car couplers.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A fluorescent magnetic particle flaw detector for car couplers includes a flaw detection box. A rotating disk is rotatably connected to the rear inner wall of the flaw detection box. Two support plates, arranged symmetrically on the left and right sides, are fixedly connected to the front end of the rotating disk. A bidirectional threaded rod is rotatably connected between the two support plates. Two movable plates are threaded onto the bidirectional threaded rod, and the two movable plates are respectively fitted onto the two parts of the bidirectional threaded rod with opposite thread directions. A clamping plate is fixedly connected to the front end of each of the two movable plates. A gasket is fixedly connected to the end of each clamping plate that is close to each other. A car coupler workpiece is placed between the two clamping plates. A gear is rotatably connected to the inner rear wall of the flaw detection box. A gear ring is fixedly fitted on the cylindrical surface of the rotating disk. The gear meshes with the gear ring. A motor that drives the gear to rotate is fixedly installed at the rear end of the flaw detection box. A rotating rod is rotatably connected to the right end of the support plate located on the right side. The rotating rod is coaxially and fixedly connected to a bidirectional threaded rod. A handle is fixedly connected to the right end of the rotating rod. A threaded rod is provided on the handle. The threaded rod passes through the handle and is threadedly connected to it. A torsion column is fixedly connected to the right end of the threaded rod. A friction block is fixedly connected to the left end of the threaded rod.

[0008] To better achieve the above objectives, the present invention adopts a further technical solution: an L-shaped support rod is fixedly connected to the left end of the flaw detection box, a spray nozzle is fixedly connected to the support rod, a liquid storage tank is fixedly connected to the left end of the flaw detection box, a transmission pipe is provided at the upper end of the liquid storage tank, one end of the transmission pipe is connected to the liquid storage tank and the other end is connected to the spray nozzle.

[0009] To better achieve the above objectives, the present invention adopts a further technical solution: the friction block is made of rubber.

[0010] The advantages of this utility model are: it can clamp the coupler workpiece and drive the clamped coupler workpiece to rotate, preventing the two clamping plates clamping the coupler workpiece from loosening due to external force rotation. The rotating coupler workpiece is sprayed with a spray nozzle, thus eliminating the need for manual spraying of fluorescent magnetic powder liquid, improving safety and increasing the efficiency of spraying fluorescent magnetic powder liquid.

Detailed Implementation

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0016] Reference Figures 1-3As shown, a fluorescent magnetic particle flaw detector for a car coupler includes a flaw detector box 1. A rotating disk 2 is rotatably connected to the rear inner wall of the flaw detector box 1. Two support plates 3, arranged left and right respectively, are fixedly connected to the front end of the rotating disk 2. A bidirectional threaded rod 4 is rotatably connected between the two support plates 3. Two movable plates 5 are threaded onto the bidirectional threaded rod 4. The two movable plates 5 are respectively fitted onto the two parts of the bidirectional threaded rod 4 with opposite thread directions. A clamping plate 6 is fixedly connected to the front end of each of the two movable plates 5. A gasket 7 is fixedly connected to the end of each clamping plate 6 that is close to each other. The rear ends of the two movable plates 5 are connected to the rotating disk 2. The sliding contact of disc 2 serves as a limiting mechanism. When the bidirectional threaded rod 4 rotates, it can drive the two moving plates 5 to move closer or further apart, causing the two clamping plates 6 to move synchronously. A hook workpiece 8 is placed between the two clamping plates 6. The movement of the two clamping plates 6 closer together clamps and fixes the hook workpiece 8 in place by the gaskets 7 on the two clamping plates 6. A gear 10 is rotatably connected to the rear inner wall of the flaw detection box 1. A gear ring 9 is fixedly fitted on the cylindrical surface of the rotating disc 2. The gear 10 meshes with the gear ring 9. A motor 11 is fixedly installed at the rear end of the flaw detection box 1 to drive the rotation of the gear 10. Gear 10 rotates, driving gear ring 9 to rotate, which in turn drives rotating disk 2 to rotate. Rotating disk 2 drives the hook workpiece 8, which is clamped and fixed by two clamping plates 6, to rotate. A rotating rod 12 is rotatably connected to the right end of the support plate 3 on the right side. The rotating rod 12 is coaxially and fixedly connected to a double-threaded rod 4. A handle 13 is fixedly connected to the right end of the rotating rod 12. A threaded rod 14 is provided on the handle 13, passing through and threadedly connected to it. A torsion column 15 is fixedly connected to the right end of the threaded rod 14, and a friction block 16 is fixedly connected to the left end of the threaded rod 14. Through rotation... The handle 13 can drive the rotating rod 12 to rotate, and the rotation of the rotating rod 12 drives the bidirectional threaded rod 4 to rotate. By rotating the handle 13, the direction of rotation can be controlled to control whether the two clamping plates 6 move closer to each other or move further away from each other. Rotating the torsion column 15 drives the threaded rod 14 to rotate, causing the friction block 16 to move toward the corresponding support plate 3 and abut against the corresponding support plate 3. The friction block 16 is made of rubber and has good anti-slip performance and high friction. By abutting against the corresponding support plate 3, the handle 13 is locked in place, preventing the two clamping plates 6 clamping the coupler workpiece 8 from loosening due to rotation caused by external force.

[0017] An L-shaped support rod 17 is fixedly connected to the left end of the flaw detection box 1. A spray nozzle 18 is fixedly connected to the support rod 17. A liquid storage tank 19 is fixedly connected to the left end of the flaw detection box 1. A transmission pipe 20 is provided at the upper end of the liquid storage tank 19. One end of the transmission pipe 20 is connected to the liquid storage tank 19 and the other end is connected to the spray nozzle 18. Fluorescent magnetic powder liquid is stored inside the liquid storage tank 19 and is transmitted to the spray nozzle 18 through the transmission pipe 20. The spray nozzle 18 is used to spray the coupler workpiece 8.

[0018] In use, rotating the handle 13 drives the rotating rod 12 to rotate, which in turn drives the bidirectional threaded rod 4 to rotate. This causes the two clamping plates 6 to move closer together, thereby clamping and fixing the coupler workpiece 8 using the gaskets 7 on the two clamping plates 6. Rotating the torsion column 15 drives the threaded rod 14 to rotate, causing the friction block 16 to move towards and abut against the corresponding support plate 3. The friction block 16 abuts against the corresponding support plate 3, thus securing the handle 13 and preventing it from clamping the coupler due to external force rotation. When the two clamping plates 6 of workpiece 8 loosen, the motor 11 drives the gear 10 to rotate, which in turn drives the gear ring 9 to rotate, thereby driving the rotating disk 2 to rotate. The rotating disk 2 drives the coupler workpiece 8, which is clamped and fixed by the two clamping plates 6, to rotate. The liquid storage tank 19 stores fluorescent magnetic powder liquid, which is transmitted to the spray nozzle 18 through the transmission pipe 20. The spray nozzle 18 sprays the rotating coupler workpiece 8, thus eliminating the need for manual spraying of fluorescent magnetic powder liquid, improving safety and increasing the efficiency of spraying fluorescent magnetic powder liquid.
