Each connecting rod surface is provided with a QR code, and the scanning camera 54 scans the QR code information on the connecting rod surface, and then stores this information corresponding to the information of the small end bottom hole measured later.

[0036] A measuring assembly 3 is provided on the bottom plate 12, and the measuring assembly 3 is used to measure the inner diameter of the small end of the connecting rod.

[0040] The implementation principle of the above embodiment is:

[0041] Before measuring, the operator adjusts the position and angle of the scanning camera 54 through the camera support Z axis 52 and the camera support rotation axis 53 .

[0042] In the next step, the preceding robot (not shown) directly places the connecting rod with the small end bottom hole processed on the tooling plate 13, and locates the connecting rod by the locating pin on the tooling plate 13 (after the preceding robot places the connecting rod, when the small end of the connecting rod moves to the bottom of the measuring component 3, the small end of the connecting rod faces the pneumatic and electrical measuring head 34).

[0043] The operator starts the control system 6 to drive the servo motor 21, and the servo motor 21 moves to the scanning station and then stops. The control system 6 drives the scanning camera 54, and the scanning camera 54 scans the two-dimensional code on the connecting rod.

[0044] The servo motor 21 drives the tooling plate 13 to continue to move according to the program. When the tooling plate 13 moves to the measuring station just below the horizontal plate in the corner seat 31, the tooling plate 13 stops moving.

[0045] The control system 6 controls the ultra-thin cylinder 42 to move according to the program. The ultra-thin cylinder 42 drives the pressing block 43 to move downward. The pressing block 43 presses the connecting rod to limit the initial position of the connecting rod.

[0046] Next, the control system 6 starts the three-rod cylinder 33 according to the program, and the three-rod cylinder 33 drives the probe bracket 34 to move downward. The probe bracket 34 drives the pneumatic and electric probe 35 to enter the small hole end of the connecting rod and then stop. The probe bracket 34 measures the radial size of the upper half of the small hole.

[0047] Next, the pneumatic and electrical probe 35 continues to move downward, so that the pneumatic and electrical probe 35 measures the radial dimension of the lower half of the small hole in the connecting rod.

[0048] The results of the two measurements are uploaded to the display screen for display and computer analysis and storage through the communication system in the control system 6.

[0049] When the measurement is finished, the control system 6 drives the pressing block 43 and the pneumatic and electrical probe 35 to return to the initial position according to the program.

[0050] After the servo motor 21 drives the tooling plate 13 to continue to move to the unloading station, the subsequent manipulator takes out the connecting rod.

[0051] The control system 6 continues to drive the servo motor 21 to move according to the program, and the servo motor 21 returns the tooling plate 13 to the initial position.

[0052] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
