[0033] Specifically, refer to Figure 1 , Figure 3A plurality of clamping members 130 are arranged on the conveyor belt 110, and the clamping members 130 are fixedly connected to the conveyor belt 110. The clamping members 130 are used to clamp the two end surfaces of the flange workpiece 1. The conveyor belt 110 drives the plurality of clamping members 130 to approach the detection structure 120 one by one. The clamping members 130 include a clamping seat 131 and a clamping block 132 arranged on the clamping seat 131. The clamping seat 131 is fixedly connected to the conveyor belt 110. The plurality of clamping seats 131 are arranged at equal distances on the outer side of the entire conveyor belt 110 along the conveying direction of the conveyor belt 110, so that the flange workpiece 1 is in order. The flange workpiece 1 can slide on the conveyor belt 110 to improve the stability of the flange workpiece 1 during transportation; a flange embedding groove 133 for embedding the flange workpiece 1 is provided on the clamping seat 131, and two clamping blocks 132 are provided on each clamping seat 131.

In this embodiment, the end surfaces of the two clamping blocks 132 away from the bottom of the flange embedding groove 133 are provided with guide arc surfaces 134, and the convex arc surfaces of the two guide arc surfaces 134 are opposite to each other and the top end spacing of the two clamping blocks 132 is greater than the bottom end spacing of the two clamping blocks 132.

The output shafts of the tapered guide column 121 and the drive motor 123 are coaxially connected through a connecting bearing 124. The tapered guide column 121 is used for the flange workpiece 1 to be set. The L-shaped detection rod 122 is composed of a short rod 1221 and a long rod 1222. One end of the short rod 1221 is vertically connected to one end of the long rod 1222. The length direction of the long rod 1222 is radially arranged along the tapered guide column 121. One end of the long rod 1222 away from the short rod 1221 is connected to the output shaft of the drive motor 123. The drive motor 123 is used to drive the L-shaped detection rod 122 to rotate axially along the tapered guide column 121. It is dynamically connected to the driving motor 123, and the short rod 1221 is used to stick to the side wall of the flange workpiece 1. Since the tapered guide column 121 and the output shaft of the driving motor 123 are coaxially connected, and the short rod 1221 of the L-shaped detection rod 122 is attached to the flange workpiece 1, that is, the sizes of the tapered guide column 121 and the L-shaped detection rod 122 are just adapted to the flange workpiece 1 to be inspected. If the position and size of the through hole of the flange workpiece 1 are accurate, the L-shaped detection rod 122 just sticks to the flange workpiece 1 and goes around the flange workpiece 1 for one circle; if the position of the through hole of the flange workpiece 1 is incorrect or the size of the through hole deviates from the preset value, the L-shaped detection rod 122 cannot make circumferential motion around the flange workpiece 1, which is an unqualified processed product.

[0036] In addition, reference Figure 4 A pressure sensor 125 is embedded on the side wall of the short rod 1221 close to the tapered guide column 121. The side wall of the pressure sensor 125 is flush with the side wall of the short rod 1221.

In this embodiment, an unqualified collection cylinder 126 is arranged between the conveyor belt 110 and the detection structure 120, and the two unqualified processed products are pushed into the unqualified collection cylinder 126 through the conveying structure.

[0037] Furthermore, a limiting disc 140 is coaxially arranged between the conical guide column 121 and the driving motor 123, and a limiting member 141 is arranged on the column wall of the conical guide column 121.

The limit block 1411 is partially embedded in the limit groove 142. The side wall of the limit block 1411 is used to contact the end face of the flange workpiece 1. When the flange workpiece 1 is sleeved on the tapered guide column 121 until the hole wall of the flange workpiece 1 is pressed against the limit block 1411, the limit spring 1412 is in the state of being pressed against the limit block 1411. 12 is gradually compressed until the limit block 1411 is completely embedded in the limit groove 142, the flange workpiece 1 continues to slide close to the limit disk 140, and the through hole wall of the flange workpiece 1 is no longer pressed on the limit block 1411. The rebound force of the limit spring 1412 drives the limit block 1411 to slide in the direction away from the bottom of the limit groove 142 until the limit block 1411 is partially embedded in the limit groove 142. At this time, one side wall of the limit block 1411 abuts against an end face of the flange workpiece 1 away from the limit disk 140, and the limit disk 140 and the limit block 1411 respectively abut against two end faces of the flange workpiece 1, which can reduce the probability of the flange workpiece 1 being offset or falling off during the detection process, thereby ensuring the stability and reliability of the detection process. In this embodiment, two groups of limit members 141 are provided, and the two groups of limit members 141 are symmetrically arranged on the column wall of the tapered guide column 121.

The first conveying component 150 and the second conveying component 160 cooperate to convey the flange workpiece 1 from the conveyor belt 110 to a state of being sleeved on the conical guide column 121, thereby improving the efficiency of detection.

[0039] refer to Figure 2-Figure 6 The first conveying component 150 is used to clamp the flange workpiece 1.

In this embodiment, the adjusting inner rod 1521 is L-shaped, and the other end of the adjusting inner rod 1521 is connected to the flange clamp 151.

[0041] The two first screw motors 1132 work synchronously to drive the two first adjusting screws 1131 to rotate synchronously, thereby driving the two sliding blocks 114 to slide downward and approach the conveyor belt 110 at the same time. After the two flange clamps 151 clamp the two sides of the flange workpiece 1 on the conveyor belt 110, the first screw motor 1132 works to drive the first adjusting screw 1131 to rotate in the opposite direction, thereby driving the sliding block 114 to slide upward to the same height as the conical guide column 121, and then the adjusting cylinder 153 works to drive the flange workpiece 1 to approach the conical guide column 121.
