Technical Field
[0001] This utility model relates to the field of magnetic particle testing technology, and in particular to a clamping device for magnetic particle testing. Background Technology
[0002] Magnetic particle inspection is a method of observing defects using magnetic powder as the display medium. Depending on the type of magnetic powder medium applied during magnetization, the inspection method is divided into wet and dry methods. According to the time when magnetic powder is applied to the workpiece, the inspection method is divided into continuous method and residual magnetism method. After a ferromagnetic material workpiece is magnetized, due to the existence of discontinuities, the magnetic lines of force on and near the surface of the workpiece are locally distorted, generating a leakage magnetic field. This field attracts the magnetic powder applied to the surface of the workpiece, forming a visible magnetic mark under suitable lighting, thus showing the location, size, shape, and severity of the discontinuity. This is also known as magnetic particle inspection or magnetic particle flaw detection.
[0003] Most existing magnetic particle testing equipment is used for shaft parts or ring-shaped materials, so it adopts a clamping method from both sides. However, when using sheet materials, thin plates, or long strip materials, excessive clamping force can easily cause material deformation and make it difficult to observe the material, making it inconvenient to use.

[0015] This clamping device for magnetic particle inspection, with its base plate and support frame, allows for easy placement of smaller or thinner materials directly on the base plate, avoiding difficulty in clamping. When clamping sheet or disc-shaped materials, the sliding rod can be pulled to the left, displacing the connected gripper and positioning the material at the top of the clamping seat. Subsequently, the spring returns, causing the sliding rod to reset, allowing the gripper to clamp the material. During clamping, the outer clamping block contacts the material surface and moves towards the inner clamping block, fitting around the outer side of the inner clamping block to conform to the material's shape and prevent horizontal displacement. Then, the electric telescopic cylinder at the top of the clamping device pushes the electromagnet to contact the material surface to magnetize the material. The compression spring prevents excessive contact force from the electromagnet, which could cause deformation or damage to the material. Attached Figure Description

[0025] The clamping assembly 7 includes a slide bar 701, a gripper 702 is bolted to the right side of the slide bar 701, an inner clamping block 703 and an outer clamping block 704 are provided on the inner side of the gripper 702, and a tension spring 705 is bolted to the left side of the support frame 2, and the left side of the tension spring 705 is bolted to the slide bar 701.
[0026] In this embodiment: by setting a base plate 1 in conjunction with a support frame 2, when inspecting smaller or thin materials, the material can be placed directly on the base plate 1, avoiding difficulty in clamping. When clamping sheet or disc-shaped materials, the slide bar 701 can be pulled to the left, causing the connected gripper 702 to move and the material to the top of the clamping seat 8. Then, the tension spring 705 rebounds, causing the slide bar 701 to return to its original position, so that the gripper 702 clamps the material. During clamping, the outer clamping block 704 will contact the material surface and move to the position of the inner clamping block 703, while fitting outside the inner clamping block 703 to conform to the shape of the material and prevent the material from moving horizontally. Then, the electric telescopic cylinder 4 at the top of the suspension clamp can push the electromagnet 6 to contact the material surface to magnetize the material. The compression spring 5 can prevent the electromagnet 6 from contacting the material with excessive force, which could cause material deformation or damage.
[0027] As a technical optimization of this utility model, the telescopic cylinder 4 is bolted to a limiting telescopic rod 9, and the bottom of the limiting telescopic rod 9 is bolted to an electromagnet 6.
[0028] In this embodiment: by setting the limiting telescopic rod 9, the displacement of the electromagnet 6 can be limited, avoiding tilting or rotation that would prevent it from being used normally.
[0029] As a technical optimization of this utility model, a telescopic spring 10 is bolted to the left side of the inner side of the inner clamping block 703, and the right side of the telescopic spring 10 is bolted to the outer clamping block 704.
[0030] In this embodiment: by setting the telescopic spring 10, it is easy to connect the outer clamping block 704 and the inner clamping block 703, and at the same time, when the outer clamping block 704 is sleeved on the outside of the inner clamping block 703, it can push the structure to reset.
[0031] As a technical optimization of this utility model, a contact pad 11 is bonded to the inner side of the clamping seat 8, and the surface of the contact pad 11 is provided with anti-slip texture.
[0032] In this embodiment: by setting the contact pad 11, damage to the clamping position can be avoided, and the anti-slip texture can prevent the hand from slipping.
[0033] As a technical optimization of this utility model, a through groove 12 is provided on the inner side of the base plate 1, and a receiving groove 13 is bolted to the bottom of the support frame 2.
[0034] In this embodiment: by setting the through slot 12, the magnetic powder generated during operation can be easily leaked down and collected uniformly through the receiving slot 13.
[0035] As a technical optimization of this utility model, a slide 14 is slidably connected to the inner side of the through groove 12, a cross frame 15 is bolted to the top of the slide 14, and a blower 16 is installed at the bottom of the cross frame 15.
[0036] In this embodiment: by setting the slide 14, the cross frame 15 can be easily limited so that it can slide along the base plate 1, and the magnetic powder on the surface can be swept off by the blowing frame 16.
[0037] As a technical optimization of this utility model, a pull-out bracket 17 is slidably connected to the inner side of the receiving slot 13.
[0038] In this embodiment: by setting the pull-out rack 17, the magnetic powder collected inside the docking slot 13 can be easily collected for recycling.
[0039] As a technical optimization of this utility model, a connecting frame 18 is movably connected to the bottom of the base plate 1, and the inner side of the connecting frame 18 is snapped into the support frame 2.
[0040] In this embodiment: by setting the connecting frame 18, it is easy to connect the support frame 2 and the base plate 1, and it is easy to disassemble by loosening the bolts during structural maintenance.
[0041] Working principle: First, when inspecting smaller or thinner materials, the material can be placed directly on the base plate 1. When clamping sheet or disc-shaped materials, the slide bar 701 is pulled to the left, causing the connected gripper 702 to move and position the material at the top of the clamping seat 8. Then, the tension spring 705 rebounds, causing the slide bar 701 to return to its original position, allowing the gripper 702 to clamp the material. During clamping, the outer clamping block 704 contacts the material surface and moves to the position of the inner clamping block 703, while simultaneously fitting outside the inner clamping block 703 to conform to the shape of the material and prevent horizontal displacement. Then, the electric telescopic cylinder 4 at the top of the suspension clamp pushes the electromagnet 6 to contact the material surface to magnetize the material. After processing, the telescopic spring 10 pushes the structure to return to its original position for later use.
[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
