In a further embodiment, the accommodation opening 105 adopts a rectangular or isosceles trapezoidal structure, which is convenient for driving the lock pin to move on the bearing mechanism 12.

[0054] According to Figure 2 、 Figure 3 and Figure 4 As shown, the outer diameter detection mechanism 4 includes a lifting unit A41 and a deformation block 46.

A U-shaped opening 410 and rectangular openings 49 that are semi-open on both sides of the U-shaped opening 410 are formed through the deformation block 46, so as to form an elastic part 411 on the deformation block 46. The right detection clamping plate 45 connected below the elastic part 411 and the left detection clamping plate 44 connected below the deformation block 46 cooperate to clamp the outer diameter of the pin lock. The distance measuring sensor A43 provided on the deformation block 46 penetrates into the deformation block 46 and extends into the U-shaped opening 410 to detect the deformation amount of the elastic part 411. A cylinder mounting part A47 that moves up and down together with the deformation block 46 is provided on the lifting unit A41.

After the elastic part 411 is reset, the right detection clamping plate 45 and the left detection clamping plate 44 clamp the pin lock. The deformation amount of the elastic part 411 is detected by the distance measuring sensor A43 to check the outer diameter of the pin lock.

[0055] According to Figure 5 and Figure 6 As shown, the height detection mechanism 5 includes a lifting unit B55, a lifting member 54, a detection plate 56, and a distance sensor B57. The lifting member 54, the detection plate 56, and the distance sensor B57 are arranged on the lifting unit B55 to drive the lifting member 54 and the detection plate 56 to move up and down. The distance sensor B57 is located directly below the detection plate 56 to detect the displacement amount of the detection plate 56, and then detect the height of the pin lock. An installation head 53 is provided on the lifting member 54, and a pressing head 51 is detachably provided on the installation head 53. By replacing the pressing heads 51 with different diameters, the total height or the inner hole depth of the pin lock can be detected.

[0056] To ensure the accuracy of detection, according to Figure 6 As shown, a horizontal cylinder 58 is installed on the lifting unit B55. The output end of the horizontal cylinder 58 passes through the lifting unit B55 and is connected to a connecting member 59 to drive the connecting member 59 to move directly below the pressing head 51. A calibration block 52 is provided on the connecting member 59.

The output end of the pressing cylinder 726 extends into a pressing channel 7211 vertically penetrated through the inside of the conveying block 727. The pressing channel 7211 is connected to an inclined channel 7210 obliquely opened in the conveying block 727. A positioning cylinder B728 is arranged on the conveying block 727. The output end of the positioning cylinder B728 radially penetrates into the inclined channel 7210 to intercept and limit the steel balls. The output end of the pressing cylinder 726 is input into the pressing channel 7211, and the output end of the positioning cylinder B728 inputs inward to make the steel balls in the inclined channel 7210 roll downward. When the steel balls roll to fit against the output end of the pressing cylinder 726, the output end of the positioning cylinder B728 outputs outward and is clamped between the steel balls. At this time, only one steel ball can be accommodated between the output end of the pressing cylinder 726 and the output end of the positioning cylinder B728. When the output end of the pressing cylinder 726 contracts inward, the steel balls enter the pressing channel 7211 and fall onto the hemispherical grooves of the pin lock.
