[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example: Figure 1-5 As shown, this utility model provides an automatic detection device for truck axle fixing rings, including a transmission belt 1, two rotating shafts 10, two side plates 12, an outer diameter detection mechanism 13, an inner diameter detection mechanism 14, and two pushing mechanisms 15. The two side plates 12 are located on both sides of the transmission belt 1, and the two rotating shafts 10 are located at the two ends of the transmission belt 1 and the side plates 12, respectively. The rotating shafts 10 are rotatably connected to the transmission belt 1 and the side plates 12. The outer diameter detection mechanism 13 includes an L-shaped plate 2, which is fixedly connected to one of the side plates 12. A first cylinder 21 is fixedly installed at the top of the L-shaped plate 2. The driving end of the first cylinder 21 passes through the L-shaped plate 2. A fixed plate 22 is fixedly installed at the driving end of the first cylinder 21. Two symmetrically distributed moving plates 23 are provided at the bottom of the fixed plate 22. A light sensor 24 is provided on the opposite inner side of each moving plate 23. The inner diameter detection mechanism 14 and the outer diameter detection mechanism 13 have the same structure, wherein the light sensor 24 is located on the outer side of the moving plate 23.

[0018] The pushing mechanism 15 includes a second cylinder 25, which is fixed on the corresponding L-shaped plate 2. The driving end of the second cylinder 25 passes through the corresponding L-shaped plate 2. A push plate 26 is fixedly installed on the driving end of the second cylinder 25. Two symmetrically distributed support plates 17 are rotatably sleeved on the outside of the rotating shaft 10. A stepper motor 18 fixedly connected to the rotating shaft 10 is fixedly installed on one side of one of the support plates 17.

[0019] Fixed legs 3 are fixedly installed on the upper surface of both side plates 12. Fixed blocks 31 are fixedly installed on the top of the fixed legs 3 by bolts. First vertical plates 32 are fixedly installed on the opposite inner sides of the fixed blocks 31. A second vertical plate 33 is fixedly installed between the two first vertical plates 32. The second vertical plate 33 is located at the left edge of the first vertical plate 32. A third vertical plate 34 is provided on the side of the two first vertical plates 32 away from the second vertical plate 33. The height of the third vertical plate 34 is lower than that of the first vertical plate 32 and the second vertical plate 33. When the two first vertical plates 32, the second vertical plate 33 and the third vertical plate 34 are combined, they form a cube. The distance between the third vertical plate 34 and the transmission belt 1 is the height of a fixed ring, forming a discharge port.

[0020] One of the side plates 12, on the side away from the outer diameter detection mechanism 13, is provided with a first feeding mechanism 4 and a second feeding mechanism 43. The first feeding mechanism 4 includes an inclined plate 41, which is attached to the side plate 12 and corresponds to the left push plate 26. Baffles 42 are fixedly installed on the top two edges of the inclined plate 41. The second feeding mechanism 43 has the same structure as the first feeding mechanism 4, where the inclined plate 41 corresponds to the right push plate 26. The end of the transmission belt 1 away from the stepper motor 18 is provided with a third feeding mechanism 44, which has the same structure as the first feeding mechanism 4. By setting the inclined plate 41, when encountering defective products in the inner or outer diameter of the fixed ring, the push plate 26 pushes the fixed ring so that it can slowly slide into the collection box, preventing it from falling into the collection box from a height and causing wear on the fixed ring. The third feeding mechanism 44 works similarly, except that when collecting good products, a collection box needs to be placed below each inclined plate 41 in actual use.

[0021] Trapezoidal blocks 5 are fixedly installed on both sides of the third vertical plate 34. The inner side of the first vertical plate 32 is provided with trapezoidal grooves 51 that cooperate with the trapezoidal blocks 5. By setting the trapezoidal blocks 5, when it is necessary to place the fixing ring in the first vertical plate 32 and the second vertical plate 33, the outer wall of each fixing ring is fitted with the inner wall of the second vertical plate 33 and the first vertical plate 32. After it is placed, the trapezoidal blocks 5 on the third vertical plate 34 are inserted into the corresponding trapezoidal grooves 51 to form a sealed space, which makes it convenient to disassemble the third vertical plate 34 and to place the fixing ring.

[0022] Two symmetrically distributed fixed seats 6 are fixedly installed at the bottom ends of the two fixed plates 22. A double-ended screw 61 with opposite threads is rotatably installed at the bottom of the fixed seat 6. The moving plate 23 is threadedly connected to the double-ended screw 61. A limiting rod 62 is slidably clamped at the top of the moving plate 23. The limiting rod 62 is fixedly connected to the fixed seat 6. A rotating motor 63 is provided at one end of the two double-ended screws 61. The rotating motor 63 is fixedly connected to the corresponding double-ended screw 61 and fixed on the fixed seat 6. By setting the double-ended screws 61, when the rotating motor 63 starts, it drives the double-ended screws 61 to rotate. Since the threads of the two ends of the double-ended screws 61 are opposite, the two moving plates 23 will move relative to each other or in opposite directions under the action of the threads. At the same time, the limiting rod 62 can prevent the moving plate 23 from rotating, ensuring its smooth movement. Thus, the spacing of the moving plates 23 can be adjusted according to the fixed rings of different specifications, adapting to the detection requirements of the inner or outer diameter of the fixed rings of different diameters, improving the versatility of the detection device.

[0023] A stabilizing plate 7 is fixedly installed between the two side plates 12. The top surface of the stabilizing plate 7 is in contact with the lower inner wall surface of the transmission belt 1. By setting the stabilizing plate 7, the transmission belt 1 is supported and stabilized, preventing the transmission belt 1 from shaking during rotation and ensuring that the fixing ring moves smoothly on the transmission belt 1.

[0024] Each push plate 26 and each moving plate 23 is fixedly installed with a rubber pad 8 at its bottom end. By setting the rubber pad 8, the transmission belt 1 is protected and wear is prevented when the push plate 26 pushes and when the moving plate 23 moves down and comes into contact with the transmission belt 1.

[0025] The optical sensor 24, the first cylinder 21, the second cylinder 25, the stepper motor 18, and the rotary motor 63 are all electrically connected to an external controller. By setting up the controller, it is convenient to control the first cylinder 21, the second cylinder 25, the stepper motor 18, and the rotary motor 63. The controller selected is a PLC controller. The optical sensor 24 mainly converts light signals into electrical signals. The optical sensor 24 converts photon flow into electrical energy in the form of electrons through the photoelectric effect, thereby realizing the detection and measurement of light. The photoelectric effect is the basis for the operation of the optical sensor 24. According to the different photoelectric effects, the optical sensor 24 can be divided into external photoelectric effect, internal photoelectric effect, and photovoltaic effect.

[0026] Working principle: In actual use, multiple fixed rings are placed in the cubic space formed by the first vertical plate 32, the second vertical plate 33, and the third vertical plate 34. Then, the stepper motor 18 is started by the controller, which drives the rotating shaft 10 and the transmission belt 1 to rotate, so that the fixed ring at the bottom of the cube is conveyed out of the discharge port. When the first fixed ring is conveyed to the area directly below the moving plate 23 in the outer diameter detection mechanism 13, the transmission belt 1 stops conveying. The first cylinder 21 in the outer diameter detection mechanism 13 drives the moving plate 23 and the light sensor 24 to move down. At the same time, the first cylinder 21 in the inner diameter detection mechanism 14 is also started. Then, the light sensor 24 emits a light signal to the surface of the fixed ring. When the outer diameter detected by the light sensor 24 is consistent with the set threshold, it is considered qualified. Then, the signal is fed back to the controller, and the fixed ring is conveyed through the transmission belt 1.

[0027] When the fixed ring with the outer diameter detected reaches directly below the moving plate 23 in the inner diameter detection mechanism 14, the transmission belt 1 stops conveying. Then, the next fixed ring with the outer diameter not detected is located directly below the moving plate 23 in the outer diameter detection mechanism 13. Subsequently, the controller controls the two first cylinders 21 to start simultaneously, driving the moving plate 23 and the light sensor 24 to move down. The fixed rings with the outer diameter not detected are detected, and the fixed rings with the outer diameter detected are detected for the inner diameter. The detection results are then fed back to the controller. Good products continue to be conveyed directly and then fall into the collection box.

[0028] If the outer or inner diameter of the fixed ring is detected to be outside the set threshold, the controller will receive a prompt and activate the corresponding second cylinder 25 to move the push plate 26, which will then push out the defective product for collection. When it is necessary to detect fixed rings with different inner diameters, the fixed rings of different diameters are placed directly below the moving plate 23. Then, the controller starts the rotating motor 63 to rotate the double-headed screw 61, which moves the moving plate 23 to the center or both sides. Before this, the threshold of the light sensor 24 needs to be set. When the moving plate 23 moves, the light sensor 24 detects that it has moved to the set threshold and sends a signal to the controller, which controls the rotating motor 63 to shut off. The first vertical plate 32, the second vertical plate 33, and the third vertical plate 34 need to be replaced with first vertical plates 32, second vertical plates 33, and third vertical plates 34 that can hold the corresponding fixed rings. When disassembling, the bolts connecting the fixed block 31 to the fixed leg 3 diameter can be removed. It should be noted that the length of the fixed block 31 also needs to be changed accordingly.

[0029] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
