[0002] Mechanical parts are the basic units that constitute mechanical equipment. They work together through different connection methods and transmission mechanisms to complete various mechanical movements and functions. There are many types of mechanical parts, which can be divided into connectors, transmission parts, supports, seals and control components according to their functions. Axle pins are common mechanical parts. When processing mechanical parts such as axle pins, loading and unloading devices are required.

[0003] In traditional axle pin processing production lines, the axle pins to be processed are usually placed on the conveyor belt manually. It is difficult to accurately control the spacing during manual placement, resulting in inconsistent distances between adjacent axle pins, which in turn affects the subsequent process. The axle pin loading and unloading devices mostly rely on manual operation, with a low degree of automation, and cannot achieve continuous and efficient automated production, limiting the production capacity of the entire production line. This method is not only labor-intensive, but also inefficient. Summary of the invention

[0031] An inclined guide plate 33 is fixedly connected to the surface of the arc plate 22, and the inclined guide plate 33 corresponds to the position of the discharge port 23. When the conveying trough 4 follows the turntable 3 to rotate to the position corresponding to the discharge port 23, the shaft pin 44 inside the conveying trough 4 falls through the discharge port 23 to the surface of the inclined guide plate 33, and then the material is discharged through the inclined guide plate 33.

The detection device 48 performs defect detection on the surface of the shaft pin 44, and the detection data and pictures are displayed in real time on the display screen 54.

[0034] A mounting plate 46 is fixedly mounted on the surface of the detection plate 37, and two mounting connecting plates 47 are correspondingly fixedly mounted on the bottom surface of the mounting plate 46, and two detection devices 48 are fixedly connected to the two mounting connecting plates 47. An electric telescopic rod 50 is fixedly mounted on the middle bottom surface of the mounting plate 46, and the electric telescopic rod 50 is a conventional electric control push rod in the prior art.

[0036] The use steps of the present invention are as follows: when the loading and unloading device for machining and testing mechanical parts is used, after the machining of the shaft pin 44 is completed, the surface of the shaft pin 44 needs to be inspected to prevent cracked and concave shaft pins 44 from entering the market. When inspecting the surface of the shaft pin 44, the shaft pin 44 is rolled and unloaded through the inclined guide plate 33. The shaft pin 44 follows the inspection plate 37 and then passes through the guide slope 45, so that the shaft pin 44 is between the second rotating roller 42 and the first rotating roller 39 (note that the elastic force of the second spring 43 is greater than the gravity of the shaft pin 44 itself). At this time, the controller 55 controls the motor 52 The detection device 48 detects defects on the surface of the shaft pin 44, and the detection data and pictures are displayed on the display screen 54 in real time. When the surface of the shaft pin 44 is qualified, the motor 52 stops working. At this time, the controller 55 controls the electric telescopic rod 50 to extend with the lower pressure plate 49, so that the lower pressure plate 49 presses the shaft pin 44. When the second roller 42 is squeezed by the shaft pin 44, the moving block 41 moves in the slot 40 to squeeze the second spring 43, thereby realizing the movement of the second roller 42, so that the second roller The distance between the first roller 39 and the shaft pin 42 increases. When the shaft pin 44 falls off, the second roller 42 is reset under the action of the second spring 43. The shaft pin 44 slides down through the blanking plate 53 and collects the shaft pin 44. When the surface detection of the shaft pin 44 fails, the display screen 54 presents an abnormal picture, and then the controller 55 receives and processes the signal, so that the alarm 51 sounds an alarm. At this time, the personnel only need to manually remove the unqualified shaft pin 44. When the surface of the shaft pin 44 is detected in this scheme, the shaft pin 44 is rolled and discharged through the inclined guide plate 33, and the shaft pin 44 is rolled and discharged along the inclined guide plate 33. The shaft pin 44 is moved along the detection plate 37 and then through the guide slope 45, so that the shaft pin 44 is between the second roller 42 and the first roller 39. The motor 52 rotates to drive the first roller 39 to rotate, so that the shaft pin 44 rotates during the detection process. The detection device 48 performs defect detection on the surface of the shaft pin 44. The detection data and pictures are displayed on the display screen 54 in real time. Compared with the traditional manual detection of the shaft pin 44, the device realizes the rotation of the shaft pin 44 during the detection process, so that the detection device 48 can detect the surface of the shaft pin 44 more completely, thereby improving the efficiency of the surface detection of the shaft pin 44.The controller 55 controls the motor 52 to rotate, thereby realizing the rotation of the shaft pin 44 during the detection process. The detection device 48 performs defect detection on the surface of the shaft pin 44, and the detection data and pictures are displayed on the display screen 54 in real time. When the surface of the shaft pin 44 is qualified, the motor 52 stops working. At this time, the controller 55 controls the electric telescopic rod 50 to extend with the lower pressure plate 49, thereby causing the lower pressure plate 49 to press the shaft pin 44 downward. When the second rotating roller 42 is squeezed by the shaft pin 44, the moving block 41 moves in the slot 40 to squeeze the second spring 43, thereby realizing the movement of the second rotating roller 42, so that the second rotating roller 42 is The distance between the second roller 42 and the first roller 39 increases. When the shaft pin 44 falls, the second roller 42 is reset under the action of the second spring 43. The shaft pin 44 slides through the blanking plate 53 and collects the shaft pin 44. When the surface detection of the shaft pin 44 fails, the display screen 54 presents an abnormal picture, and then the controller 55 receives and processes the signal, so that the alarm 51 sounds an alarm. At this time, the personnel only need to manually remove the unqualified shaft pin 44, so as to realize the automatic intelligent detection of the shaft pin 44. The device has a faster detection speed for the shaft pin 44 and a higher detection quality for the shaft pin 44. ;
