[0024] like Figure 1 , Figure 5and Figure 6 As shown, a material trough 16 is provided in the middle of the material plate 22, and a guide frame 21 is provided at one end of the material trough 16 away from the pushing assembly 15, and the guide frame 21 is arranged on one side of the outer surface of the vertical plate 1, and a pushing assembly 15 for assisting in loading and unloading of materials is installed at one end of the material trough 16, and the pushing assembly 15 comprises a fixed side plate 1501, an electric push rod 1502 and a rubber push plate 1503, and an electric push rod 1502 is provided on the outer surface of the fixed side plate 1501, and a rubber push plate 1503 is installed on the output end of the electric push rod 1502.

[0025] In summary, if Figure 1-Figure 6As shown, the pin sleeve inner hole concentricity detection device, when in use, is designed that the material trough 16 is recessed in the material plate 22, so that the pin sleeve is placed inside the material trough 16. After the placement is completed, the rubber push plate 1503 can be moved by the design of the fixed side plate 1501 and the electric push rod 1502. The position movement of the rubber push plate 1503 can push the pin sleeve placed inside the material trough 16 to the outside of the two groups of positioning plates 1404, which is beneficial to use the two groups of positioning plates 1404 to support and fix the inner hole of the pin sleeve. In addition, when the concentricity detection of the pin sleeve is completed, the pin sleeve can be placed in the initial position in the material trough 16, which is convenient for re-activating the electric push rod 1502 to drive the rubber push plate 1503 to move, which is beneficial to push the pin sleeve after the concentricity detection is completed. The pin sleeves are sent to the guide frame 21 for unified collection of the pin sleeves after the inspection is completed, wherein the pin sleeves are placed inside the material trough 16, and the built-in plate 19 at the end of the threaded rod 18 can be controlled to move relative to the material trough 16 by rotating the threaded rod 18, so as to align the pin sleeves placed in the material trough 16, and facilitate the subsequent use of the positioning plate 1404 to quickly support and fix the inner hole of the pin sleeve. During the loading inspection, the drive motor 2 and the conveyor belt 3 are designed to drive the transmission shaft 4 to rotate, and the rotation of the transmission shaft 4 can drive the side plate 801 and the transmission rod 802 connected thereto to follow, and at the same time, the connecting rod 803 and the vertical plate 804 will rotate synchronously, so that the connecting shaft 901 and the connecting shaft 902 connected to the vertical plate 804 follow, and the solid surface of the connecting shaft 902 The fixed frame 1201 will rotate accordingly, so that the entire fixed frame 1201 will adjust or reset to one side of the material plate 22. During the process of adjusting the angle of the fixed frame 1201 to one side, the gear 1 903 and the gear 2 1202 will mesh with each other, so that the gear 2 1202 will rotate, and the built-in shaft 1204 connected to the gear 2 1202 and the positioning frame 13 will follow the movement, which is beneficial to use the design of the positioning component 14 inside the positioning frame 13 to limit the inner hole of the pin sleeve in the material plate 22. After limiting, the above-mentioned angle adjustment makes the pin sleeve after limiting consistent with the detection position of the concentricity detector 5, which is beneficial to use the concentricity detector 5 to perform concentricity detection on the pin sleeve, improves the detection efficiency, and can also be used after the detection is completed by positioning the positioning frame 13. The angle adjustment again realizes the automatic collection of the pin sleeve after the concentricity detection. When the positioning frame 13 fixes the pin sleeve, the design of the servo motor 1401 and the shaft can drive the screw rod 1402 to rotate. The threads on the outer surfaces of the two ends of the screw rod 1402 are in opposite directions, so that the threaded sleeve plate 1403 and the positioning plate 1404 can be close to or away from each other when the screw rod 1402 rotates, so that the positioning plate 1404 can be extended into the inner hole of the pin sleeve for support and fixation.
