Description

Technical Field

[0001] The utility model relates to the technical field of magnetic particle flaw detection, in particular to a supporting device that is convenient for magnetic particle flaw detection of cylindrical parts. Background Art

[0002] Magnetic particle inspection utilizes the interaction between the leakage magnetic field at the defects of the workpiece and the magnetic powder. It utilizes the difference in magnetic permeability between the surface and near-surface defects of steel products (such as cracks, slag inclusions, hairline, etc.) and the magnetic permeability of steel. After magnetization, the magnetic field at the discontinuity of these materials will be distorted, forming a leakage magnetic field on the surface of the workpiece where some magnetic flux leaks, thereby attracting magnetic powder to form magnetic powder accumulation magnetic marks at the defects. Under appropriate lighting conditions, the defect position and shape are revealed, and the accumulation of these magnetic powders is observed and interpreted to achieve magnetic particle inspection.

[0004] The above-mentioned device needs to be fitted with a boss of corresponding size according to the diameter of the cylindrical part. However, the thickness of cylindrical parts with different diameters requires different widths of the recessed grooves, which may result in the inability to firmly fix and support the cylindrical part, and the adaptation time is also long, which is time-consuming and labor-intensive, and the support effect on the cylindrical part is poor.

[0027] The first rotating shaft 4 and the second rotating shaft 5 are both provided with two supporting wheels for supporting the cylindrical member. The first rotating shaft 4 is rotatably connected with the driving motor 7, and the driving motor 7 is fixed on the swing vertical plate 6. Preferably, the driving motor 7 is a servo motor to facilitate the control of the rotation speed. The strip support 1 is provided with an adjustment mechanism for adjusting the distance between the first rotating shaft 4 and the second rotating shaft 5.

[0028] When the present solution is in use, the cylindrical part can be placed horizontally on four supporting wheels, and the wheel discs 23 on the four supporting wheels can make rolling contact with the cylindrical part. The adjustment mechanism can be used to adjust the distance between the first rotating shaft 4 and the second rotating shaft 5, so that the wheel disc 23 can better adapt to and support cylindrical parts of different radial sizes, and the driving motor 7 can be used to drive the cylindrical part to rotate smoothly, so that the cylindrical part can cooperate with external equipment to perform magnetic particle flaw detection.

[0029] Example 2

[0030] like Figures 2 to 4As shown, based on Example 1, this embodiment provides a specific scheme of the adjustment mechanism, the adjustment mechanism includes a pull rod 8 and a driving mechanism for pulling the pull rod 8 to move, the two ends of the pull rod 8 are vertically hinged to one end of the first swing block 9 and the second swing block 10 respectively, the other end of the first swing block 9 is rotatably connected to a transmission shaft 11 limited on the bar support 1, a driving gear 12 is provided on the transmission shaft 11, the first transmission rod 2 is fixedly sleeved with a driven gear 13 meshing with the driving gear 12, and the other end of the second swing block 10 is fixedly sleeved on the second transmission rod 3.

[0031] During the design, the driving mechanism includes a pulling block 14 fixedly connected to one end of the pull rod 8, a vertically extending slide groove 15 is provided on the pulling block 14, a slider 16 is movably provided in the slide groove 15, a mounting seat 17 is provided on the strip support 1, a screw rod 18 is provided on the mounting seat 17, the outer end of the screw rod 18 is rotationally limited on the mounting seat 17, and a handwheel 21 is provided on the outer end of the screw rod 18 for facilitating the rotation of the screw rod 18, and the inner end of the screw rod 18 passes through the pulling block 14 and is threadedly matched with the slider 16.

Therefore, the pulling block 14 is provided with an avoidance groove 19 for avoiding the inner end of the screw rod 18 and a strip avoidance hole 20 for the screw rod 18 to pass through.
