Description

Technical Field

[0001] This invention relates to the field of automotive parts testing technology, specifically a multi-dimensional defect detection device and application method for aluminum alloy wheel hub production. Background Technology

[0002] Aluminum alloy wheels are an important component of modern automobiles. Made of lightweight aluminum alloy through precision casting or forging processes, they are significantly lighter than traditional steel wheels, effectively reducing unsprung mass and improving handling and fuel economy. Their excellent heat dissipation performance quickly dissipates heat generated during braking, extending the life of the braking system. Furthermore, aluminum alloy wheels offer diverse appearances, with electroplating and painting processes creating stylish and cool designs to meet individual needs. They also possess corrosion resistance and high strength, withstanding complex road conditions and providing reliable protection for driving safety, making them a popular choice for automotive upgrades and modifications.

[0003] During the production of aluminum alloy wheels, defect detection equipment is often used to ensure product quality. However, traditional aluminum alloy wheel inspection equipment mostly uses industrial inspection cameras for visual inspection, which is a relatively simple method. Furthermore, traditional wheel inspection equipment requires fixing the wheel during inspection, and the traditional fixing structure can easily cause excessive obstruction of the wheel, thus affecting the inspection results. Therefore, this paper proposes a multi-dimensional defect detection device and application method for aluminum alloy wheel production to address the above problems. Summary of the Invention

[0004] In view of the problems mentioned in the background art, the purpose of this invention is to provide a multi-dimensional defect detection device for aluminum alloy wheel hub production, so as to solve the problems mentioned in the background art.

[0005] Meanwhile, the present invention also provides an application method for a multi-dimensional defect detection device used in the production of aluminum alloy wheels.

[0006] The technical solution adopted by the present invention to solve its technical problem is: a multi-dimensional defect detection device for aluminum alloy wheel hub production, including a detection table, a mounting frame fixedly installed on the top of the detection table, a cylinder fixedly installed on the top of the mounting frame, a lifting frame fixedly installed on the telescopic end of the cylinder, an X-ray emitter and a radiation detector fixedly installed on the two side walls of the lifting frame respectively, the lifting frame being slidably connected to the inner side of the mounting frame, a fixing frame fixedly installed on one side of the mounting frame, an industrial inspection camera fixedly installed on one side of the fixing frame, an adjustment mechanism provided on the inner side of the detection table, a placement frame provided on the top of the adjustment mechanism, and a clamping mechanism provided on the inner side of the placement frame; The adjustment mechanism includes a through hole, which is opened inside the testing platform. A first screw is rotatably connected to the inside of the through hole. A first motor is fixedly installed at one end of the testing platform. The output end of the first motor is fixedly installed at one end of the first screw. An adjustment plate is threadedly connected to the outside of the first screw. The adjustment plate is slidably connected to the inside of the through hole. A rotating base is rotatably connected to the top of the adjustment plate. A second motor is fixedly installed at the bottom of the adjustment plate. The output end of the second motor is fixedly installed at the center of the rotating base. The placement frame is fixedly installed on the top of the rotating base. The clamping mechanism includes a fixed rod, which is symmetrically fixedly installed on one side of the placement frame. A connecting rod is slidably connected to the other side of the placement frame. A crossbar is fixedly installed at the top of one end of the connecting rod. Clamping rods are symmetrically fixedly installed at the top of the crossbar. A support block is fixedly installed at the top of the rotating seat. A second screw is rotatably connected between the support block and the placement frame. A screw block is fixedly installed at one end of the second screw through the support block. The end of the connecting rod away from the crossbar is threadedly connected to the second screw.

[0007] Preferably, a slide rod is fixedly installed on the inner side of the through hole, and one end of the adjusting plate is slidably connected to the outer side of the slide rod.

[0008] Preferably, the inner side of the placement rack is symmetrically provided with sliding grooves, one side of the crossbar is slidably connected to the sliding groove, a reinforcing block is fixedly installed between the crossbar and the clamping rod, a mating block is fixedly installed at the bottom of the end of the connecting rod away from the crossbar, the mating block is threaded to the outside of the second screw, a sliding hole is provided on one side of the placement rack, and one end of the connecting rod extends into the inner side of the placement rack through the sliding hole.

[0009] Preferably, the inner side of the mounting frame is symmetrically provided with sliding grooves, and the lifting frame and the mounting frame are slidably connected by the sliding grooves.

[0010] This invention provides an application method for a multi-dimensional defect detection device used in the production of aluminum alloy wheels, characterized by the following steps: The wheel hub is placed on the mounting frame, resting against the fixed rod of the mounting frame. Then, the second screw is rotated between the support block and the mounting frame using a swivel block, causing the connecting rod threaded on the outer side of the second screw to slide on the mounting frame. The connecting rod pushes the crossbar on the inner side of the mounting frame to slide, allowing the clamping rod on the crossbar to clamp the other side of the wheel hub. Then, the output end of the first motor drives the first screw to rotate in the through hole, causing the adjusting plate threaded on the outer side of the first screw to slide, moving the wheel hub to the inspection area. The telescopic end of the cylinder on the mounting frame extends and retracts, pushing the lifting frame to slide, allowing the X-ray emitters and radiation detectors at both ends of the lifting frame to perform multi-point inspection according to the inspection standards, and to cooperate with the visual inspection of the industrial inspection camera. The output end of the second motor drives the rotary seat to rotate above the adjusting plate, which can facilitate flipping during visual inspection.

[0011] The advantages of this invention are: 1. This invention uses the telescopic end of the cylinder on the mounting frame to push the lifting frame to slide, so that the X-ray emitters and radiation detectors at both ends of the lifting frame can perform multi-point inspection according to the inspection standards. In addition, with the visual inspection of the industrial inspection camera, the inspection quality and quality assurance of the wheel hub can be greatly improved. 2. By placing the wheel hub on the placement frame and combining it with the rod-type clamping structure, this invention can significantly reduce the obstruction of the wheel hub during inspection, expand the inspection range to a certain extent, and ensure the inspection quality. At the same time, the clamping mechanism and the placement frame are mounted on the adjustment mechanism. The adjustment mechanism can meet the flipping action during inspection by the industrial inspection camera through movement and rotation, thereby greatly improving the inspection efficiency.

Example 1

[0016] The following is in conjunction with the appendix Figures 1-4 To further illustrate this application, an embodiment of this application discloses a multi-dimensional defect detection device for aluminum alloy wheel hub production.

Through the sliding grooves 11 on the mounting frame 2, and with a suitable slide provided on the outside of the lifting frame 4, the lifting frame 4 can slide easily on the inner side of the mounting frame 2. The wheel hub X-ray inspection can detect the cavities formed by gas accumulation inside the wheel hub, the non-compact internal structure of the wheel hub material with gaps, and foreign objects or particles of different materials mixed inside the wheel hub. Combined with the visual inspection of the industrial inspection camera 12, the inspection quality of the wheel hub can be further ensured. The X-ray emitter 5 and the X-ray detector 6 are relatively mature existing technology products on the market, so they will not be described in detail here. The adjustment mechanism 9 includes a through hole 904, which is located inside the testing platform 1. A first screw 902 is rotatably connected to the inside of the through hole 904. A first motor 903 is fixedly installed at one end of the testing platform 1. The output end of the first motor 903 is fixedly installed at one end of the first screw 902. An adjustment plate 901 is threadedly connected to the outside of the first screw 902. The adjustment plate 901 is slidably connected to the inside of the through hole 904. A rotating seat 905 is rotatably connected to the top of the adjustment plate 901. A second motor 906 is fixedly installed at the bottom of the adjustment plate 901. The output end of the second motor 906 is fixedly installed at the center of the rotating seat 905. A placement frame 8 is fixedly installed on the top of the rotating seat 905. A slide rod 13 is fixedly installed inside the through hole 904. One end of the adjustment plate 901 is slidably connected to the outside of the slide rod 13. Through the slide rod 13 at the through hole 904, the adjustment plate 901 can slide within the through hole 904. The output end of the first motor 903 drives the first screw 902 to rotate in the through hole 904, causing the adjustment plate 901 threadedly connected to the outside of the first screw 902 to slide. The adjustment plate 901 can move the hub located on the placement frame 8 above to the inspection area for inspection.

A clamping rod 147 is symmetrically fixedly installed at the top of the crossbar 142. A support block 146 is fixedly installed at the top of the rotary seat 905. A second screw 144 is rotatably connected between the support block 146 and the placement frame 8. A rotating block 145 is fixedly installed at one end of the second screw 144 through the support block 146. The end of the connecting rod 143 away from the crossbar 142 is threadedly connected to the second screw 144, thus connecting the wheel... The hub is placed on the mounting bracket 8, abutting against the fixing rod 141 of the mounting bracket 8. Then, the second screw 144 is rotated between the support block 146 and the mounting bracket 8 by the rotating block 145. This causes the connecting rod 143, which is threaded on the outer side of the second screw 144, to slide on the mounting bracket 8. The connecting rod 143 pushes the crossbar 142 on the inner side of the mounting bracket 8 to slide, and the clamping rod 147 on the crossbar 142 can clamp the other side of the hub. The fixing rod 141, the clamping rod 147, and the mounting bracket 8 are all equipped with rubber outer structures to prevent the hub from being scratched during the clamping process and to avoid affecting the inspection.

[0017] Reference Figure 4The inner side of the placement rack 8 is symmetrically provided with sliding grooves 15. One side of the crossbar 142 is slidably connected to the sliding groove 15. A reinforcing block 16 is fixedly installed between the crossbar 142 and the clamping rod 147. A mating block 18 is fixedly installed at the bottom of the end of the connecting rod 143 away from the crossbar 142. The mating block 18 is threaded to the outside of the second screw 144. A sliding hole 17 is provided on one side of the placement rack 8. One end of the connecting rod 143 extends into the inner side of the placement rack 8 through the sliding hole 17 and passes through the sliding groove 15 on the placement rack 8. The crossbar 142... A suitable slide is provided below 42, which allows the crossbar 142 to slide stably inside the placement frame 8. The reinforcing block 16 between the crossbar 142 and the clamping rod 147 can improve the strength of the clamping rod 147. The connecting rod 143 is connected to the outside of the second screw 144 by a threaded hole in the mating block 18 at the bottom of the connecting rod 143. The connecting rod 143 can slide on the placement frame 8 by a sliding hole 17 on one side of the placement frame 8. Example 2

[0018] Based on the structure of Example 1, the application method of the multi-dimensional defect detection device for aluminum alloy wheel hub production of the present invention includes the following steps: The wheel hub is placed on the mounting bracket 8, abutting against the fixing rod 141 of the mounting bracket 8. Then, the second screw 144 is rotated between the support block 146 and the mounting bracket 8 by the rotating block 145, causing the connecting rod 143, which is threaded on the outer side of the second screw 144, to slide on the mounting bracket 8. The connecting rod 143 pushes the crossbar 142 on the inner side of the mounting bracket 8 to slide, allowing the clamping rod 147 on the crossbar 142 to clamp the other side of the wheel hub. Then, the first screw 902 is driven by the output end of the first motor 903. Rotation in the through hole 904 causes the adjusting plate 901, which is threadedly connected to the outer side of the first screw 902, to slide, moving the hub to the inspection area. The extension and retraction of the cylinder 3 on the mounting frame 2 pushes the lifting frame 4 to slide, allowing the X-ray emitter 5 and the radiation detector 6 at both ends of the lifting frame 4 to perform multi-point inspection according to the inspection standards, and cooperate with the visual inspection of the industrial inspection camera 12. Meanwhile, the output end of the second motor 906 drives the rotating seat 905 to rotate above the adjusting plate 901, which can facilitate flipping during visual inspection.
