[0035] The setting of the lifting module 1 can make the wheel 5 move upward and close to the ultrasonic probe 63, which is convenient for subsequent flaw detection;

[0036] The mobile module 2 includes a support frame 22 , one side of the support frame 22 is fixedly connected to the U-shaped bracket 16 , and the lower side of the support frame 22 is fixedly connected to a group of Forma wheels 21 .

[0037] When it is necessary to perform flaw detection on the wheel 5, the device is pushed, and a set of Forma wheels 21 rotate through the support frame 22 to drive the lifting module 1 to move, so that the cylinder 47 of the fixed module 4 moves and passes through the middle of the wheel 5, so that the wheel 5 is sleeved on the cylinder 47, which saves time and effort.

[0038] The fixing module 4 includes a cylinder 47, and the central axis of one end of the cylinder 47 is movably connected to one side of the T-shaped slide plate 13. A cross-shaped slide groove 46 is provided in the middle of the cylinder 47, and a slider 44 is provided in the middle of the cross-shaped slide groove 46. The slider 44 is threadedly connected to a wire lever 42, and one end of the wire lever 42 passes through and is movably connected to one side of the cylinder 47. One end of the wire lever 42 is fixedly connected to the center of the turntable 2 45, and the slider 44 is respectively connected to a group of connecting rods 43 through pin hinges.

[0039] One end of a group of connecting rods 43 is respectively connected to the corresponding top plate 41 through a pin hinge.

[0040] A group of the top plates 41 are respectively arranged at the cross-shaped sliding grooves 46 .

[0041] The module 4 is fixed so that a set of top plates 41 contact the wheel 5, so that the wheel 5 is fixed.

[0042] The detection module 6 includes a guide rod 64 , one end of which is fixedly connected to one side of the U-shaped bracket 16 .

[0045] The upper side of the sleeve 62 is threadedly connected to the top screw 61 .

[0046] According to the need of flaw detection, the position of the ultrasonic probe 63 is adjusted, and the wheel 5 is rotated so that the wheel 5 drives the fixing module 4 to rotate, and the ultrasonic probe 63 performs flaw detection on the wheel 5 .

[0047] Working principle: When it is necessary to perform flaw detection on the wheel 5, Figure 3As shown, the wheel 5 is placed upright, and the device is pushed. A set of Forma wheels 21 rotate through the support frame 22 to drive the lifting module 1 to move, so that the cylinder 47 of the fixed module 4 moves and passes through the middle of the wheel 5, as shown in FIG. Figure 1 As shown, the wheel 5 is sleeved on the cylinder 47, which saves time and effort. At this time, stop pushing the device and rotate the second turntable 45. The second turntable 45 drives the wire lever 42 to rotate, and the wire lever 42 drives the slider 44 to slide. The slider 44 drives a group of connecting rods 43 to swing, and a group of connecting rods 43 drives the corresponding top plates 41 to move away from each other along the cross-shaped slide groove 46, so that a group of top plates 41 contacts the wheel 5. At this time, stop rotating the second turntable 45, so that the wheel 5 is fixed on the cylinder 47;

[0048] Then, the lifting module 1 is started, and the turntable 11 is rotated to drive the screw 12 to rotate, and the screw 12 drives the T-shaped slide plate 13 to slide upward, and the T-shaped slide plate 13 drives the corresponding ball slider 14 to slide upward along the linear guide rail 15. At the same time, the T-shaped slide plate 13 drives the wheel 5 and the fixed module 4 to move upward, so that the wheel 5 moves upward and fits the detection surface of the ultrasonic probe 63. Figure 2 As shown, at this time, the rotation of the turntable 11 is stopped, and then the position of the ultrasonic probe 63 is adjusted according to the needs of the flaw detection, the top screw 61 is loosened, and the sleeve 62 is moved, so that the sleeve 62 drives the ultrasonic probe 63 to move along the guide rod 64, and the ultrasonic probe 62 is moved to the position where the wheel 5 needs to be flaw detected. At this time, the sleeve 62 is stopped from moving, and the top screw 61 is tightened, so that the top screw 61 is against the guide rod 64 to prevent the sleeve 62 from sliding randomly, thereby causing the error of the flaw detection. At this time, the wheel 5 is rotated, so that the wheel 5 drives the fixing module 4 to rotate, and the ultrasonic probe 63 can perform flaw detection on the wheel 5.

[0049] Beneficial effect: when it is necessary to perform flaw detection on the wheel 5, the device is pushed, a group of Forma wheels 21 rotate through the support frame 22 to drive the lifting module 1 to move, so that the cylinder 47 of the fixing module 4 moves and passes through the middle of the wheel 5, so that the wheel 5 is sleeved on the cylinder 47, which is more time-saving and labor-saving. Through the fixing module 4, a group of top plates 41 contact the wheel 5, so that the wheel 5 is fixed on the cylinder 47, and the lifting module 1 is started to move the wheel 5 upward and fit the detection surface of the ultrasonic probe 63. According to the needs of flaw detection, the position of the ultrasonic probe 63 is adjusted, and the wheel 5 is rotated, so that the wheel 5 drives the fixing module 4 to rotate, and the ultrasonic probe 63 performs flaw detection on the wheel 5.
