Description

Technical Field

[0001] The utility model belongs to the technical field of magnetic particle flaw detection, and particularly relates to a fluorescent magnetic particle flaw detection device. Background Art

[0002] Magnetic particle flaw detection utilizes the interaction between the leakage magnetic field at the workpiece defect and the magnetic powder. It makes use of the difference in magnetic permeability between the surface and near-surface defects (such as cracks, slag inclusions, hair cracks, etc.) of steel products and the magnetic permeability of steel. After magnetization, the magnetic field at these material discontinuities will be distorted, forming a partial magnetic flux leakage, and a leakage magnetic field is generated on the workpiece surface, thus attracting magnetic powder to form a magnetic powder accumulation - magnetic trace at the defect. Under appropriate light source conditions, the position and shape of the defect are revealed. By observing and interpreting the accumulation of these magnetic powders, magnetic particle flaw detection is achieved.

[0003] The existing magnetic particle flaw detection devices are relatively large in size. The magnetic yoke, magnetic powder, black light, etc. are all installed separately, with low integration and unable to adapt to the flaw detection of small parts.

[0004] Therefore, in view of the above problems, further improvements are made. Content of the Utility Model

[0005] The main purpose of the utility model is to provide a fluorescent magnetic particle flaw detection device, which is linked through a bracket module, a magnetic yoke module and a magnetic powder module, so as to integrally detect parts, and has the advantages of stable structure, high practicability and wide application range.

[0006] To achieve the above object, the utility model provides a fluorescent magnetic particle flaw detection device, including a bracket module, a magnetic yoke module and a magnetic powder module. The magnetic yoke module and the magnetic powder module are both installed on the bracket module, wherein:

[0007] The bracket module includes a first bracket unit and a second bracket unit. The first bracket unit includes a top plate, a bottom plate, a first vertical plate and a second vertical plate. The first vertical plate and the second vertical plate are respectively fixedly installed between the top plate and the bottom plate. The second bracket unit includes a connecting piece, a cylinder mounting plate, a stop rod mounting rod and a stop rod. One end of the connecting piece is fixedly installed on the top plate and the cylinder mounting plate is fixedly installed at the other end of the connecting piece. The stop rod mounting rod is fixedly installed on the cylinder mounting plate and the stop rod is fixedly installed on the stop rod mounting rod.

[0008] The magnetic yoke module includes a magnetic yoke, a first fixing piece and a second fixing piece. The magnetic yoke is installed on the bottom plate through the first fixing piece and the second fixing piece, and a black light is installed on the magnetic yoke.

[0009] The magnetic powder module includes a rotary cylinder, a powder spreading container mounting member, and a powder spreading container. The rotary cylinder is mounted on a side of the cylinder mounting plate away from the stop rod mounting rod, and the powder spreading container mounting member is fixedly mounted on a driving end of the rotary cylinder. The powder spreading container is fixedly mounted on the powder spreading container mounting member, and the stop rod is located on a side of the powder spreading container close to the magnetic yoke (to prevent the rotary cylinder from driving the powder spreading container to rotate excessively and hitting a black light or the like, causing damage).

[0010] As a further preferred technical solution of the above technical solution, the black light is mounted on the magnetic yoke through a black light mounting bracket.

[0011] As a further preferred technical solution of the above technical solution, the powder spreading container mounting member includes a flat plate member and a bending member. The flat plate member is fixedly mounted on the driving end of the rotary cylinder, and two ends of the bending member are fixedly mounted on the flat plate member.

[0012] As a further preferred technical solution of the above technical solution, the support module includes a spring mounting seat. The spring mounting seat includes a mounting flange, an upper spring mounting member, a lower spring mounting member, a shock-absorbing spring, and a guide rod. The lower spring mounting member is fixedly mounted on the top plate, and the shock-absorbing spring is mounted between the upper spring mounting member and the lower spring mounting member. The mounting flange is fixedly mounted on a side of the upper spring mounting member away from the shock-absorbing spring. The shock-absorbing spring is sleeved on the guide rod (the spring mounting seat enables the entire flaw detection device to be mounted on the equipment. When a downward force is applied to the mounting flange, the upper spring member slides down along the guide rod because it is sleeved on the guide rod, so that the shock-absorbing spring is compressed, thereby achieving the shock-absorbing effect).

[0013] As a further preferred technical solution of the above technical solution, the black light faces an outlet of the powder spreading container. Description of the Drawings
