Description

Technical Field

[0001] This utility model relates to the field of magnetic yoke flaw detection technology, and in particular to a special workbench for magnetic yoke flaw detection. Background Technology

[0002] In industrial production, many workpieces need to be inspected for surface defects (such as cracks, slag inclusions, etc.) after welding.

[0003] Magnetic particle testing is a common non-destructive testing method based on the magnetization properties of ferromagnetic materials. When a ferromagnetic workpiece is magnetized, the presence of discontinuities causes local distortion of the magnetic field lines on and near the workpiece surface, resulting in a leakage magnetic field. When magnetic powder is applied to the workpiece surface, the leakage magnetic field attracts the powder, forming a visible magnetic trace under suitable illumination. This trace reveals the location, size, shape, and severity of the discontinuity.

[0004] In magnetic particle testing, a magnetic yoke flaw detector is commonly used. The workpiece is placed on a platform, and a layer of contrast enhancer is sprayed onto its surface. After drying, a black oil magnetic suspension is sprayed on top. Then, the two magnetic poles of the magnetic yoke flaw detector are brought into contact with the workpiece surface, magnetizing it. Magnetic marks will then appear on the workpiece located between the two magnetic poles. However, during the spraying of the contrast enhancer and black oil magnetic suspension, some reagents can easily splash onto the outside of the platform, posing a problem for cleaning.

The workbench body is also provided with a recovery mechanism for recovering black oil magnetic suspension.

[0008] Furthermore, the recycling mechanism includes a drawer that is horizontally and linearly slidably installed inside the main body of the workbench. A slide groove is provided on one side of the main body of the workbench for the drawer to slide. Multiple waste discharge ports are provided on the main body of the workbench along the circumference of the detection area for the black oil magnetic suspension to flow into the drawer.

[0009] Furthermore, the main body of the workbench has a groove in the testing area, and the waste discharge port is located at the edge of the bottom wall of the groove.

[0010] Furthermore, the mounting bracket is provided with a mounting base, and the lighting lamp is rotatably mounted on the mounting base via a ball joint. The bottom of the mounting base is provided with a spherical groove for accommodating the ball joint, and a lamp holder is connected to the ball joint.

[0019] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0020] This application discloses a special workbench for magnetic yoke flaw detection, referring to... Figure 1 , Figure 2 and Figure 3The system includes a main workbench 1, on which a testing area for placing workpieces is provided. A mounting bracket 2 is bolted to the main workbench 1, and a lighting lamp 3 is installed on the mounting bracket 2 above the testing area. A shield 4 is installed on the mounting bracket 2 outside the testing area, and an operating opening is provided on one side of the mounting bracket 2. The main workbench 1 is also equipped with a recovery mechanism 5 for recovering black oil magnetic suspension.

[0021] In this embodiment, the shielding cover 4 is a cloth curtain. The curtain is hung on the mounting frame 2, allowing the operator to place the workpiece in the inspection area through the operating port. Then, a contrast enhancer and black oil magnetic suspension are sequentially sprayed onto the workpiece surface. Following this, a magnetic yoke flaw detector can be used for flaw detection. During flaw detection, the magnetic traces on the workpiece can be carefully observed using the illumination lamp 3. During spraying, the cloth curtain prevents the contrast enhancer and black oil magnetic suspension from splashing onto the outside of the workbench body 1. The black oil magnetic suspension on the workbench body 1 can be recovered using the recovery mechanism 5. This improves the ease of cleaning the contrast enhancer and black oil magnetic suspension.

[0022] Specifically, the recycling mechanism 5 includes a drawer 51 that is horizontally and linearly slidably installed inside the workbench body 1. A slide groove is provided on one side of the workbench body 1 for the drawer 51 to slide. Multiple waste outlets 11 are provided on the workbench body 1 along the circumference of the detection area for the black oil magnetic suspension to flow into the drawer 51.

[0023] In this embodiment, the black oil magnetic suspension sprayed in the testing area can flow into the drawer 51 through the waste outlet 11. After the flaw detection operation is completed, the staff can remove the drawer 51 and process the recovered black oil magnetic suspension in a unified manner.

[0024] Furthermore, a groove 12 is provided on the main body of the workbench 1 in the detection area, and the waste discharge port 11 is located at the edge of the bottom wall of the groove 12.

[0025] In this embodiment of the application, the workpiece is placed in the groove 12 for flaw detection. Some of the black oil magnetic suspension sprayed onto the surface of the workpiece flows into the groove 12 and is blocked by the side wall of the groove 12, which can prevent the black oil magnetic suspension from flowing to the outside of the worktable body 1.

[0026] Furthermore, a mounting base 6 is bolted to the mounting bracket 2, and the lighting lamp 3 is rotatably mounted on the mounting base 6 via a ball joint 7. A spherical groove for accommodating the ball joint 7 is provided at the bottom of the mounting base 6, and a lamp holder 31 is bolted to the ball joint 7, on which the lighting lamp 3 is mounted. A limiting element is provided on the mounting base 6 to restrict the rotation of the ball joint 7.

[0027] In this embodiment, rotating the lighting lamp 3 can adjust the illumination angle of the light so that the staff can observe the magnetic marks on the surface of the workpiece.

[0028] Specifically, the limiting component includes a limiting bolt 8. A threaded hole is horizontally opened on one side of the mounting base 6. The limiting bolt 8 is threadedly connected in the threaded hole and moves against the ball joint 7.

[0029] In this embodiment, tightening the limiting bolt 8 and making it abut against the ball joint 7 can restrict the rotation of the lighting lamp 3; loosening the limiting bolt 8 allows the lighting lamp 3 to rotate.

[0030] To further improve the illumination effect on the workpiece surface, multiple lighting lamps 3 are provided on the mounting bracket 2.

[0031] To facilitate the storage of the magnetic yoke flaw detector, a material loading trough 9 is bolted to the bottom of the main body 1 of the workbench.

[0032] The implementation principle of the magnetic yoke flaw detection workbench in this application embodiment is as follows: During the spraying process, a cloth curtain prevents the contrast enhancer and black oil magnetic suspension from splashing onto the outside of the workbench body 1, and the black oil magnetic suspension on the workbench body 1 can be recovered by the recovery mechanism 5. This improves the ease of cleaning the contrast enhancer and black oil magnetic suspension.
