The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0018] The first embodiment of the present application is:

[0019] See also Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the overall structure of the fluorescent magnetic particle flaw detector for ring parts of the first embodiment of the utility model. Figure 2 It is a structural schematic diagram of the moving component of the first embodiment of the utility model.

[0020] The utility model of the ring-shaped fluorescent magnetic particle flaw detector includes a flaw detector body 101, a support plate 102, a movable frame 103, a guide cylinder 104, a guide column 105, an upper spray pipe 106, a lower spray pipe 107, a drive motor 108, a cam plate 109, a connecting seat 110, and a connecting rod 111. It solves the problem that the magnetic suspension needs to be sprayed on the workpiece through a nozzle to magnetize and magnetize the workpiece, while the nozzle position of the prior art is fixed, which easily leads to uneven spraying. It is understandable that the above scheme can also be used to improve the quality of flaw detection.

[0021] In this embodiment, the flaw detector body 101 is the prior art, and is installed on the flaw detector body 101 through the spray assembly, thereby solving the problem that the magnetic suspension needs to be sprayed on the workpiece through the nozzle to magnetize and magnetize the workpiece, while the nozzle position of the prior art is fixed, which easily leads to uneven spraying.

[0022] The support plate 102 is fixedly connected to the flaw detector body 101 and is located on one side of the flaw detector body 101. The movable frame 103 is connected to the support plate 102 through the support member. The support member is installed on the support plate 102 and supports the movable frame 103. The upper spray pipe 106 is installed on the movable frame 103. The lower spray pipe 107 is installed on the movable frame 103 and is located on a side of the movable frame 103 away from the upper spray pipe 106. The movable member drives the movable frame 103 to move. The support plate 102 is L-shaped and fixedly installed on the top of the flaw detector body 101. The movable frame 103 is U-shaped and is installed on the support plate 102 through the support member. The number of the support members is two groups, which are used to provide support and guidance for the movable frame 103. A plurality of nozzles are provided on the upper spray pipe 106. The upper spray pipe 106 is evenly arranged along the length direction, and the plurality of spray heads can be operated simultaneously to spray the magnetic suspension on the workpiece. The lower spray pipe 107 is the same as the upper spray pipe 106. The upper spray pipe 106 is located at the inner top of the movable frame 103, and the lower spray pipe 107 is located at the inner bottom of the movable frame 103. The two are arranged oppositely and staggered. The movable member is used to drive the movable frame 103 to move back and forth, thereby expanding the spraying area of ​​the upper spray pipe 106 and the lower spray pipe 107, so as to better cope with workpieces of different sizes. By arranging two sets of opposing, staggered and movable spray pipes on the flaw detector body 101 to spray the magnetic suspension, the purpose of uniform spraying is achieved, which solves the problem that the magnetic suspension needs to be sprayed on the workpiece through the spray head to magnetize and magnetize the workpiece, and the position of the spray head in the prior art is fixed, which is easy to cause uneven spraying.

[0023] Secondly, the guide cylinder 104 is fixedly connected to the support plate 102 and is located on a side of the support plate 102 close to the movable frame 103; the guide column 105 is slidably connected to the guide cylinder 104 and fixedly connected to the movable frame 103.

Through the guide cylinder 104 and the guide column 105, the movable frame 103 is supported and guided.

[0024] At the same time, the driving motor 108 is installed on the supporting plate 102 and is located on the side of the supporting plate 102 away from the guide cylinder 104; the cam disc 109 is fixedly connected to the output shaft of the driving motor 108; the connecting piece is respectively connected to the movable frame 103 and the cam disc 109, and the driving motor 108 is fixed to the back side of the supporting plate 102 by bolts. The cam disc 109 is composed of an axle rod, a disc and a pin rod. The axle rod is located at the center of the bottom of the disc and is fixedly connected to the output shaft of the driving motor 108. The pin rod is eccentrically arranged on the top surface of the disc. The connecting piece is used to connect the cam disc 109 and the movable frame 103. The cam disc 109 is driven to rotate by the driving motor 108, and cooperates with the connecting piece to drive the movable frame 103 to reciprocate.

[0025] In addition, the connecting seat 110 is fixedly connected to the movable frame 103 and is located on a side of the movable frame 103 close to the cam disk 109; the two ends of the connecting rod 111 are rotatably connected to the connecting seat 110 and the cam disk 109 respectively, and a through groove is opened on the support plate 102, one end of the connecting rod 111 is connected to the connecting seat 110 through a bearing, and the other end of the connecting rod 111 passes through the through groove and is connected to the pin rod on the cam disk 109 through a bearing. The setting of the through groove can avoid interference with the movement of the connecting rod 111, and through the connecting seat 110 and the connecting rod 111, the cam disk 109 is rotated while driving the movable frame 103 to reciprocate.

[0026] In this embodiment, when performing flaw detection, the workpiece is fixed on the two electrode chucks of the flaw detector body 101, and the workpiece is magnetized and rotated, and the upper spray pipe 106 and the lower spray pipe 107 spray magnetic suspension from above and below the workpiece. At the same time, the drive motor 108 is actuated to drive the cam plate 109 to rotate, so that the upper spray pipe 16 and the lower spray pipe 107 reciprocate at the same time, thereby ensuring the comprehensiveness of the magnetic suspension spraying, and solving the problem that the magnetic suspension needs to be sprayed on the workpiece through the nozzle to magnetize and magnetize the workpiece, while the nozzle position in the prior art is fixed, which easily leads to uneven spraying.

[0027] The second embodiment of the present application is:

[0028] See also Figure 3 , Figure 3 20 is a schematic diagram of the overall structure of the annular fluorescent magnetic particle flaw detector according to the second embodiment of the utility model. Based on the first embodiment, the annular fluorescent magnetic particle flaw detector according to this embodiment further includes a mounting plate 201 and a shaft sleeve 202 .

[0029] In this embodiment, the moving component further includes a mounting plate 201 and a shaft sleeve 202, and the stability can be improved through the above solution.

A bearing is arranged in the shaft sleeve 202, and the cam disc 109 passes through the shaft sleeve 202 and is fixedly connected to the inner ring of the bearing, so that the cam disc 109 can be supported and rotated at the same time, and the cam disc 109 is stably supported through the mounting plate 201 and the shaft sleeve 202, thereby improving the stability.

[0031] In this embodiment, since the cam plate 109 is directly connected to the output shaft of the driving motor 108 and has poor stability, the cam plate 109 is stably supported by the mounting plate 201 and the bushing 202, thereby improving stability.

[0032] What is disclosed above is only one or more preferred embodiments of the present application, and cannot be used to limit the scope of rights of the present application. Ordinary technicians in this field can understand that all or part of the processes of implementing the above embodiments and equivalent changes made according to the claims of the present application are still within the scope covered by the present application.
