Description

Technical Field

[0001] This utility model relates to the field of flaw detector technology, and in particular to a magnetic particle flaw detector with a shielded darkroom. Background Technology

[0002] Magnetic particle testing utilizes the fact that when ferromagnetic materials are magnetized, the discontinuities cause local distortion of the magnetic field lines on and near the workpiece surface, generating a leakage magnetic field (i.e., the magnetic field formed when magnetic induction lines leave and enter the surface). This magnetic field attracts the magnetic powder applied to the workpiece surface, forming a magnetic mark that is visible to the naked eye under suitable lighting, thus revealing the location, shape, and size of the discontinuities.

[0003] Traditional flaw detectors clamp the workpiece at both ends using fixtures, but the ends of the workpiece are not fixed and limited, resulting in poor stability during clamping. Improvements are needed to design a flaw detector structure for large workpieces. Utility Model Content

[0004] The purpose of this invention is to provide a magnetic particle flaw detector with a shielded darkroom to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A magnetic particle flaw detector with a shielded darkroom includes a frame and a shielded darkroom. A flaw detector base is provided at the top of the frame. A clamping assembly is installed on one side of the flaw detector base via a rotating rod. The clamping assembly consists of a main frame, a rotating disk, and a swing arm. A rotary motor is installed in the middle of the main frame, and the output end of the rotary motor is connected to the middle of the main frame. Two main clamping arms are movably arranged on the surface of the main frame. One end of each swing arm is movably connected to both ends of the main frame. Multiple support arms are provided on the outer wall of the frame, and the shielded darkroom is installed on the outside of the frame via the support arms.

[0007] Preferably, clamping cylinders are installed at both the top and bottom of the rotary disk, and the output end of the clamping cylinder is connected to one side of the main clamping arm.

[0008] Preferably, one end of the swing arm is threadedly connected to a screw, one end of the screw is provided with a knob, and the other end of the screw is provided with an auxiliary clamping block.

[0009] Preferably, the shielded dark box is provided with a door on the front, and the front end of the frame is provided with an operating station.

[0010] Preferably, a spray frame is provided on the side of the frame, and multiple spray heads arranged side by side are installed on the top of the spray frame.

[0011] Preferably, the top of the frame is provided with a reflux cavity, the inside of the reflux cavity is provided with a conical seat, both sides of the conical seat are provided with filter screens, the top center of the conical seat is provided with a displacement groove, a slide block is slidably installed inside the displacement groove, an electric push rod is provided inside the slide block, and the output end of the electric push rod is connected to a support platform.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] This application improves the clamping assembly of a flaw detector by installing two main clamping arms on a rotating disk, driven by a clamping cylinder. A manual screw and auxiliary clamping blocks are also installed on the swing arm. When a workpiece needs clamping, it can be placed on a support platform. The support platform can be slidable to adjust the workpiece's position. Then, an electric push rod pushes the support platform upward, moving the workpiece to the center of the rotating disk. The rotating disk then moves closer to the workpiece, clamping it from both ends for initial positioning. Simultaneously, the clamping cylinder drives the main clamping arms to further position the workpiece at its ends. For large workpieces, the swing arm can be rotated and its angle adjusted. By manually rotating the screw, the auxiliary clamping blocks can clamp other points on the workpiece's ends. This improves the workpiece's stability during rotation. Attached Figure Description

Specifically, clamping cylinders 17 are installed on the top and bottom of the rotating disk 15, and the output end of the clamping cylinder 17 is connected to one side of the main clamping arm 16. The clamping cylinder 17 is a commercially available device known to those skilled in the art. Here, we are only using it without making any structural or functional improvements, so we will not go into detail here. The main clamping arm 16 is a metal structure.

Specifically, one end of the swing arm 18 is threadedly connected to a screw 19, one end of the screw 19 is provided with a knob, and the other end of the screw 19 is provided with an auxiliary clamping block 20.

[0026] The working principle of this utility model is as follows: During processing, the door 21 is opened, and the inside of the shielded dark box 2 is entered. Standing at the operating station 4, the workpiece is taken out from the workpiece placement area and placed on the conical seat 10. It is supported by the support platform 13, which can slide to adjust the position of the workpiece. Then, the electric push rod 11 pushes the support platform 13 to rise, so that the workpiece moves to the center position of the rotating disk 15. The rotating disk 15 is equipped with a push cylinder on the back, which can push the rotating disk 15 to move it closer to the workpiece, thereby pressing the two ends of the workpiece. The workpiece is initially limited, and the clamping cylinder 17 drives the two main clamping arms 16 to further limit the end of the workpiece. For large workpieces, the swing arm 18 can be rotated and the angle of the swing arm 18 can be adjusted. By manually rotating the screw 19, the auxiliary clamping block 20 can clamp other points on the end of the workpiece. In this way, the workpiece is more stable when rotating. During processing, the rotation of the rotating rod can drive the entire main frame 14 to rotate, and at the same time drive the workpiece to rotate. During the rotation, the spray head 8 can spray the magnetic powder liquid evenly onto the workpiece.
