Description

Technical Field

[0001] This utility model relates to the field of defect marking technology for galvanized steel pipes, and in particular to a magnetic particle inspection defect marking device for galvanized steel pipes. Background Technology

[0002] The magnetic particle inspection defect marking equipment for galvanized steel pipes is a non-destructive testing (NDT) device used to detect surface and near-surface defects in galvanized steel pipes. This equipment is mainly used in industries such as machinery, automotive, military, and aerospace, and can identify defects such as cracks and inclusions caused by casting, forging, and welding processes. The basic principle of magnetic particle inspection is based on the fact that after ferromagnetic materials are magnetized, the discontinuities on the surface and near the surface cause local distortion of the magnetic field lines, forming a leakage magnetic field. These leakage magnetic fields attract magnetic particles, forming visible magnetic traces, thus revealing the location, shape, and size of the defects.

[0003] An existing magnetic particle inspection and defect marking device for galvanized steel pipes is inconvenient for operators to easily limit and fix the pipes according to their actual left and right widths when marking defects, thus reducing the flexibility of the device during the defect marking operation. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a magnetic particle inspection defect marking device for galvanized steel pipes.

[0005] This utility model is achieved by the following technical solution: a magnetic particle inspection defect marking device for galvanized steel pipe, including a workbench, a fixed frame is fixedly connected to the bottom of the workbench, a drive motor is fixedly connected inside the fixed frame, a spiral rod is fixedly connected to the output end of the drive motor, and a sliding groove is opened inside the workbench; A support bracket is fixedly connected to the top of the workbench, and a mounting frame is fixedly connected to the top of the support bracket. A limit bracket is inserted inside the mounting frame, and a cylinder is snapped into the bottom of the limit bracket. A light is fixedly connected to the output end of the cylinder. A ball bearing bracket is threaded onto the surface of the lead screw, and an adjusting frame is fixedly connected to the top of the ball bearing bracket. A locking screw is threaded onto the inside of the adjusting frame, and a limit retaining ring is threaded onto the surface of the locking screw.

[0006] As a further improvement to the above solution, the top of the drive motor contacts the bottom surface of the worktable, the lead screw is located at the bottom of the worktable, and the ball bearing bracket is slidably connected inside the worktable.

[0007] Through the above technical solution, the output end of the drive motor is fixedly connected to the spiral screw. By precisely controlling the speed and direction of the drive motor, the spiral screw can be rotated accurately, allowing the ball bearing bracket to move smoothly and accurately within the sliding groove. This, in turn, drives the adjusting frame and locking screw to adjust their positions, ensuring that the flaw detection equipment can accurately locate the defect position on the surface of the galvanized steel pipe, thus improving the accuracy and reliability of flaw detection.

[0008] As a further improvement to the above solution, the ball bearing bracket is slidably connected inside the sliding groove, and the number of the sliding groove is set to two, with the two sliding grooves symmetrically distributed around the worktable.

[0009] The above technical solution incorporates two symmetrically distributed sliding grooves inside the worktable. The ball bearing support is slidably connected within these grooves, providing stable support for the ball bearing support and ensuring its straightness and accuracy during movement. During flaw detection, this stable movement mechanism effectively reduces flaw detection errors caused by equipment shaking or vibration, guaranteeing the accuracy of the flaw detection results.

[0010] As a further improvement to the above solution, the bottom of the limiting bracket is in contact with the top surface of the bearing bracket, the cylinder is inserted into the top of the bearing bracket, and the lighting lamp is located at the bottom of the bearing bracket.

[0011] With the above technical solution, the output end of the cylinder is fixedly connected to the lighting lamp. During the flaw detection process, the cylinder can automatically adjust the position and angle of the lighting lamp as needed to provide sufficient lighting for the flaw detection area. This not only improves the convenience of operation, but also enables flaw detection personnel to perform accurate flaw detection operations under different lighting conditions. Especially when detecting small defects or complex surface structures, good lighting conditions can significantly improve the efficiency and accuracy of flaw detection.

[0012] As a further improvement to the above scheme, the number of locking screws and limiting rings is set to two, and the two locking screws and limiting rings are symmetrically distributed around the adjusting frame.

[0013] As a further improvement to the above solution, the limiting ring is located at the top of the adjusting frame, the locking screw is located at the top of the ball bearing bracket, and the limiting ring is located at the top of the ball bearing bracket.

[0014] As a further improvement to the above solution, the ball bearing bracket is located on the front of the support bracket, and the adjustable frame is located on the front of the support bracket.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention utilizes a locking screw and a limiting ring, which are threadedly connected to the adjusting frame. This threaded connection method offers high strength and stability, ensuring a secure connection of all components during flaw detection. In high-frequency flaw detection operations, the threaded connection effectively resists loosening or detachment caused by vibration and impact, guaranteeing long-term stable operation of the equipment and reducing maintenance costs and repair time. The locking screw and limiting ring also ensure even distribution of force when the equipment is under stress, facilitating convenient limiting and fixing of the galvanized steel pipe.

[0016] This invention provides a stable support platform for the lighting lamp by setting the bottom of the limiting bracket to contact the top surface of the supporting bracket, and inserting the cylinder into the top of the supporting bracket. During the flaw detection process, the supporting bracket can bear the weight of the cylinder and the lighting lamp, ensuring that it remains stable during operation and will not shake or shift due to external forces, thus ensuring the smooth progress of the flaw detection operation.
