[0034] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. This application provides a magnetic particle inspection device capable of multi-faceted inspection. Please refer to... Figures 1-6 :include,

[0035] Camera 1 takes a picture of the gear workpiece 2;

[0036] Magnetizer 3, locally magnetizes gear workpiece 2;

[0037] Suspension nozzle 4 sprays suspension onto the surface of gear workpiece 2;

[0038] For the middle part 5; the middle part 5 passes through the center of the gear workpiece 2, and the center line of the middle part 5 coincides with the axis of the gear workpiece 2;

[0039] The rotation of the central part 5 drives the gear workpiece 2 to rotate, and the camera 1, magnetizer 3, and suspension nozzle 4 sweep across the surface of the gear workpiece 2.

[0040] The U-shaped frame 6 is equipped with an ultraviolet irradiation lamp. When the camera 1 takes a picture, the ultraviolet irradiation lamp is turned on to effectively record the crack traces. The magnetizer 3 can sequentially magnetize each rack on the gear workpiece 2 for easy inspection.

[0041] The gear workpiece 2 is manually inserted into the centering part 5. The centering part 5 can lift and fix the gear workpiece 2 and rotate on its own. Before magnetization, the centering part 5 drives the gear workpiece 2 to rotate. The suspension nozzle 5 sprays the suspension onto the surface of the gear workpiece 2. Then the magnetizer 3 magnetizes the gear workpiece 2. The suspension will gather at the crack of the gear workpiece 2. The crack can be inspected by human observation and photographic recording.

[0042] Reference Figure 1 , Figure 2 , Figure 3 and Figure 5It includes a convex frame 6, an infusion tube 61 at the upper end of the convex frame 6, a suspension nozzle 4 at the lower end of the infusion tube 61, a first telescopic rod 62 at the upper end of the convex frame 6, a damping bearing 63 installed at the telescopic end of the first telescopic rod 62, a connecting plate 64 on the outer ring of the damping bearing 63, a magnetizer 3 at both ends of the connecting plate 64, and a camera 1 at the center of the connecting plate 64.

[0043] In practical applications, the suspension is sprayed from the suspension nozzle 4 through the infusion pipe 61. The first telescopic rod 62 extends, which can drive the connecting plate 64 and the magnetizer 3 to move downward until the two stages of the magnetizer 3 contact the rack on the gear workpiece 2. Then, the magnetizer 3 is energized to magnetize the gear workpiece 2. Through the action of the damping bearing 63, the magnetizer 3 is in a stationary state when there is no external force interference. When it is necessary to inspect the helical gear workpiece, the magnetizer 3 is manually rotated so that the extension direction of the magnetizer 3 is the same as the extension direction of the workpiece rack, which facilitates the energization of the magnetizer.

[0044] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 It also includes a horizontal bearing 65 disposed on the side wall of the 6-shaped frame, a rotating tube 66 installed in the inner ring of the horizontal bearing 65, a first gear 67 disposed at one end of the rotating tube 66, a first motor 68 disposed on the side wall of the 6-shaped frame, and a second gear 69 meshing with the first gear 67 disposed at the rotating end of the first motor 68.

[0045] In practical applications, the rotation of the first motor 68 can drive the rotation of the second gear 69, which in turn drives the rotation of the first gear 67 and the rotating tube 66. The rotating tube 66 can drive the gear workpiece 2 to rotate, so that the surface of the gear workpiece 2 can be swept by the camera 1, the magnetizer 3, and the suspension nozzle 4.

[0046] Reference Figure 1 , Figure 2 , Figure 3 and Figure 6 The middle part 5 includes a fixed ring 51, which is fixed at both ends of the rotating pipe 66;

[0047] The rotating ring 52 is slidably connected to the rotating tube 66;

[0048] The slide groove 53 is provided in two sets and is evenly distributed on the surface of the rotating tube 66;

[0049] Linkage assembly 54, one end of which is hinged to moving ring 52, and the other end of which is hinged to fixed ring 51; linkage assembly 54 is divided into two sections, and the hinged position in the middle of linkage assembly 54 can be raised.

[0050] A horizontal bar 55, one end of which is hinged to the raised position of the connecting rod assembly 54, and the other end of which is slidably connected to the raised position of the connecting rod assembly 54;

[0051] The second motor 56 is located at the center of the rotating tube 66;

[0052] The connecting plate 57 is slidably connected to the rotating tube 66 and partially passes through the slide groove 53. The connecting plate 57 is fixedly connected to the rotating ring 52. A threaded hole 571 is opened at the center of the connecting plate 57. The rotating end of the second motor 56 is provided with a threaded shaft 572 that meshes with the threaded hole 571.

[0053] In practical applications, the gear workpiece 2 is manually placed on the centering part 5 and brought into contact with the horizontal rod 55. The second motor 56 is controlled to rotate. The second motor 56 is a dual-axis motor that can drive two threaded shafts 572 to rotate simultaneously. The threaded shafts 572 mesh with the threaded holes 571. The rotation of the threaded shafts 572 can drive the connecting plate 57 to slide along the slide groove 53. The slide groove 53 drives the moving ring 52 to approach the fixed ring 51. At this time, the middle position of the connecting rod group 54 gradually moves away from the rotating tube 66 and drives the horizontal rod 55 to move. The rise of the horizontal rod 55 gradually drives the axis of the gear workpiece 2 to coincide with the axis of the rotating tube 66, and finally achieves the operation of fixing the gear workpiece 2.

[0054] Reference Figure 1 , Figure 2 , Figure 3 and Figure 6 The horizontal bar 55 is slidably connected to the raised position of the connecting rod assembly 54 at one end;

[0055] A groove 551 is provided on the lower surface of one end of the horizontal bar 55. A hinge plate 552 is provided in the groove 551. The hinge plate 552 is slidably connected to the groove 551. The connecting rod assembly 54 is hinged to the hinge plate 552.

[0056] In practical applications, the position of the horizontal bar 55 and the connecting rod group 54 will change. Through the sliding action of the hinge plate 552, the horizontal bar 55 and the connecting rod group 54 can slide relative to each other to avoid locking.

[0057] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 The surface of the horizontal bar 55 is provided with an anti-slip pad 553.

[0058] In practical applications, the anti-slip pad 553 can increase the friction between the gear workpiece 2 and the centering part 5.

[0060] In practical applications, the extension and retraction of the third telescopic rod 601 can drive the support frame 602 to move up and down, and the support frame 602 drives the V-shaped roller conveyor 603 to move. The V-shaped roller conveyor facilitates the movement of the gear workpiece 2. The electrical appliances in this application are electrically connected to an external controller.
