Detailed Implementation

[0032] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0033] A preferred embodiment of the present invention will be described in detail below as an auxiliary device for a wheel flaw detector.

[0034] Example 1, as Figures 1-9 As shown, it includes a support base 1, and a flaw detection mechanism 2 and a fixing mechanism 3 are arranged above the support base 1;

[0035] The upper portion of the support base 1 is provided with a first support frame 4 and a second support frame 5, the first support frame 4 is slidably installed with a support plate 6, the flaw detection mechanism 2 comprises a support block 201 fixedly installed on one side of the support plate 6, the inside of the support block 201 is slidably connected with a sliding groove 202, the support block 201 is slidably connected with a rotating piece 203 through the sliding groove 202, the rotating piece 203 is symmetrically provided with two groups, the surface of the support block 201 is slidably installed with a sliding ring 204, one side of the sliding ring 204 is fixedly installed with a return spring 205, one side of the support plate 6 close to the first support frame 4 is fixedly installed with a buffer block 206, the buffer block 206 is symmetrically provided with two groups, one side of the support plate 6 is provided with a sliding groove 207 and a buffer groove 208, the sliding groove 207 and the buffer groove 208 are symmetrically provided with two groups, the support plate 6 is slidably installed with a connecting piece 209 through the buffer groove 208, the connecting piece 209 and the buffer block 206 are fixedly installed with an elastic rope 210, one side of the connecting piece 209 close to the support block 201 is fixedly installed with an arc-shaped clamping block 211, the support plate 6 is slidably installed with a flaw detection plate 212 through the sliding groove 207, one side of the flaw detection plate 212 is fixedly installed with an ultrasonic probe 213, one side of the flaw detection plate 212 is fixedly installed with a clamping ball 214 matched with the arc-shaped clamping block 211, the connecting rod 215 is rotatably installed between the rotating piece 203 and the flaw detection plate 212;

[0036] The second support frame 5 is slidably installed with a connecting plate 7, the fixing mechanism 3 comprises a fixing cylinder 301 rotatably installed on one side of the connecting plate 7, the inside of the fixing cylinder 301 is provided with a pushing block 302, the pushing block 302 is slidably installed with a blocking block 303 through a slot, the opposite side of the rotating piece 203 is fixedly installed with a matching block 304 matched with the blocking block 303;

[0037] The worker will need to set the wheel to be detected in the surface of the fixed cylinder 301, when the second support frame 5 moves to the first support frame 4, then the wheel will be driven by the fixed cylinder 301 to the support block 201, when the push block 302 inside the fixed cylinder 301 moves, through the sliding groove 202 inside the support block 201 to its inside, while moving, the blocking block 303 inside the push block 302 contacts the matching block 304 on one side of the rotating piece 203, and drives the rotating piece 203 to move synchronously through the matching block 304, at the same time, the sliding ring 204 is pushed to compress the return spring 205, so that the return spring 205 shrinks due to elastic potential energy, the connecting rod 215 moves synchronously driven by the rotating piece 203, when the connecting rod 215 rotates, it will push the detection plate 212 to move outward, at the same time, when the detection plate 212 moves close to the buffer block 206, the clamping ball 214 on one side of the detection plate 212 will contact the arc-shaped clamping block 211, under the push of the push block 302, the clamping ball 214 and the arc-shaped clamping block 211 are clamped with each other, when the detection plate 212 drives the ultrasonic probe 213 to move to the outermost position, the detection plate 212 moves to the maximum distance it can move, at this time, when the push block 302 moves, the rotating piece 203 cannot continue to move, so that the matching block 304 generates a certain resistance, and the blocking block 303 in the push block 302 is subjected to resistance, then the blocking block 303 moves to the inside of the push block 302 due to the shape characteristics of itself and the matching block 304, at this time, because the return spring 205 shrinks due to elastic potential energy, when the blocking block 303 moves to the inside of the push block 302, the matching block 304 loses resistance, the return spring 205 pushes the sliding ring 204 to drive the rotating piece 203 to reset, at the same time, it drives the detection plate 212 to move inward, so as to drive the ultrasonic probe 213 to contact the surface of the wheel, when the fixed cylinder 301 drives the wheel to rotate, the wheel detection work can be carried out, without the worker holding the ultrasonic probe 213 to detect the wheel, at the same time, it can adapt to the size of the wheel to improve the overall applicability of the device, and the worker does not need to interfere too much, reducing the labor burden of the worker;

[0038] Simultaneously, as the flaw detection plate 212 moves the ultrasonic probe 213 to fit against the wheel surface, the locking ball 214 engages with the arc-shaped locking block 211. When the flaw detection plate 212 moves, the arc-shaped locking block 211 drives the connecting piece 209 to move synchronously. At this time, the elastic rope 210, which is fixedly connected between the buffer block 206 and the connecting piece 209, pulls the connecting piece 209, thus restricting it and causing the flaw detection plate 212 to move slowly, bringing the ultrasonic probe 213 to fit against the wheel surface. Simultaneously, the elastic potential energy of the return spring 205 pushes the ultrasonic probe 213 firmly against the wheel surface, effectively preventing excessive pressure from the ultrasonic probe 213 when in contact with the wheel, which could cause deformation of the contact surface between the ultrasonic probe 213 and the wheel, or damage to the ultrasonic probe 213, resulting in an uneven sound wave propagation path and affecting the detection... To ensure the accuracy of the test, the return spring 205 ensures that the ultrasonic probe 213 fits well against the wheel surface after contact, preventing insufficient pressure during contact. This would result in poor acoustic coupling between the ultrasonic probe 213 and the wheel, affecting the transmission efficiency of the sound waves and thus the flaw detection results. After the flaw detection is completed, the fixed cylinder 301 moves in the reverse direction, causing the wheel to separate from the ultrasonic probe 213. At this time, the return spring 205 will push the slip ring 204 to fully reset. When the return spring 205 pushes the rotating part 203 to reset through the slip ring 204, the locking ball 214 separates from the interface inside the arc-shaped locking block 211. Furthermore, the material of the arc-shaped locking block 211 has a certain elasticity, and the groove inside the pushing block 302 is provided with an elastic block that can elastically contract when the blocking block 303 is pushed, and drive the blocking block 303 to reset when the pushing force is lost.

[0039] Example 2, as Figures 1-7 As shown, a drive motor 8 is fixedly installed on the side of the connecting plate 7 away from the first support frame 4. The output end of the drive motor 8 is rotatably connected to the fixed cylinder 301. A through groove is annularly opened on the surface of the fixed cylinder 301. A locking block 9 is slidably installed inside the fixed cylinder 301 through the through groove. A connecting spring 10 is fixedly installed between the locking block 9 and the fixed cylinder 301. A wedge block 11 that cooperates with the locking block 9 is slidably installed inside the fixed cylinder 301. One side of the wedge block 11 is rotatably connected to the push block 302.

[0040] The drive motor 8 can drive the fixed cylinder 301 to rotate. When the push block 302 is pushed to move to one side of the fixed cylinder 301, the push block 302 will drive the wedge block 11 to move synchronously and contact the locking block 9, thereby driving the locking block 9 to expand outward through the through groove, so that it can be fixed from the inner diameter of the wheel, making it convenient and quick to fix the wheel.

[0041] Example 3, as Figures 1-3As shown, the top of the support seat 1 is provided with a moving groove 12, the moving groove 12 is symmetrically provided with two groups, the second support frame 5 is slidably connected with the support seat 1 through the moving groove 12, the driving plate 13 is fixedly installed between the second support frame 5, the driving cylinder 14 is fixedly installed on the top of the support seat 1, and the output end of the driving cylinder 14 is fixedly connected with the driving plate 13.

[0042] The driving cylinder 14 can drive the driving plate 13 to move, so as to drive the second support frame 5 to move synchronously, and the wheel can be conveniently pushed to the flaw detection position.

[0043] As shown in the fourth embodiment, Figure 1 The coupling box 15 is fixedly installed on the side of the second support frame 5 close to the first support frame 4, and the coupling box 15 is located directly below the fixed cylinder 301.

[0044] The coupling box 15 can inject water into the inside, and when the wheel is detected, the surface of the wheel can be placed in water, so that the air interference between the ultrasonic probe 213 and the surface of the wheel can be effectively reduced, and the transmission efficiency of the sound wave can be improved.

[0045] As shown in the fifth embodiment, Figures 1-3 The mounting plate 16 is fixedly installed on the top of the first support frame 4, the lifting cylinder 17 is fixedly installed on the top of the mounting plate 16, the moving plate 18 is arranged between the first support frame 4 and the second support frame 5, the moving plate 18 is fixedly connected with the support plate 6, the connecting plate 7 is slidably connected with the moving plate 18, and the output end of the lifting cylinder 17 is fixedly connected with the moving plate 18.

[0046] The lifting cylinder 17 can drive the moving plate 18 to move up and down, so that the support plate 6 and the connecting plate 7 can be driven to move up and down through the support plate 6, and the wheel can be driven to move into the coupling box 15.
