The connecting pipe 22 on the workpiece is set through the narrowed positioning hole 101, and the edge of the small diameter opening of the narrowed positioning hole 101 is fitted with the circumferential wall of the connecting pipe 22 with a clearance.

[0033] Among them, see Figure 2 , Figure 5 The first positioning element 4, the second positioning element 5, and the detection component 3 are provided in at least two sets. Each first positioning element 4 is placed on a turntable 7. Each turntable 7 is provided with a transmission wheel 11 that can rotate synchronously with it.

[0039] Working principle and process:

[0040] When using the product of this solution, the connecting pipe 22 of the moving disk 2 is placed on the turntable 7 through the constricted positioning hole 101. Due to the limiting and guiding effect of the constricted positioning hole 101, the connecting pipe 22 on the moving disk 2 can be directly fitted onto the first positioning member 4 to achieve positioning at the workpiece axis. After all the moving disks 2 are placed, the equipment is started. The rotating component 17 controls the second positioning member 5 to swing onto the movement path of the abutment part 23 on the moving disk 2. The rotating component 6 drives the turntable 7 to move, causing the moving disks 2 on it to follow the movement. The rotating component 6 rotates more than one revolution... The abutment part 23 on each position of the moving disk 2 can be made to abut against the second positioning member 5 in the circumferential direction to achieve positioning of the moving disk 2. Then the first drive component 32 drives the detection block 31 to slide into the connecting keyway 21 on the moving disk 2. If the connecting keyway 21 is too small, the detection block 31 will be stuck there. After the first drive component 32 has completed its movement, the sensor 18 detects the position of the detection block 31 and issues a warning for the moving disk 2 that is not within the reasonable range, and completes the screening of qualified and unqualified products.
