The connecting rod 34 and the cleaning rod 41 are both provided with limiting sliders, which are located at the limiting grooves. During the up and down movement of the connecting rod 34 and the cleaning rod 41, the limiting sliders and the limiting grooves are provided to limit their moving directions, and the connection rod 34 and the cleaning rod 41 can be effectively prevented from falling off, which is beneficial to improving the stability of the device.

[0062] Reference Figure 1 Two bottom plates 19 are fixedly connected at both ends of the base 11, and mechanical arms 191 are provided on the upper end surfaces of the bottom plates 19. Mechanical grippers 192 are connected to the mechanical arms 191, and the two mechanical arms 191 respectively control the placement and gripping of the piston rod 10. When the piston rod 10 needs to be inspected, the staff drives the mechanical arm 191 on one side of the base 11 to clamp the piston rod 10 and place it on the support table 111. After the inspection is completed, the mechanical arm 191 on the other side is used to remove it, thereby completing the inspection, reducing manpower consumption, and improving work efficiency.

[0063] The mechanical arm 191 and the mechanical gripper 192 are prior art in the embodiment of the present invention and will not be described in detail.

[0064] The implementation principle of the piston rod size surface intelligent detection device of the embodiment of the present application is as follows: when the piston rod 10 needs to be surface-detected, the staff places the piston rod 10 on the support platform 111 through the mechanical arm 191, and then starts the lifting motor 16, which drives the lifting screw 14 to rotate, thereby driving the lifting plate 17 to descend, so that the abutment block 18 is pressed against the piston rod 10, and when the lifting screw 14 rotates, it also synchronously drives the bidirectional screw 21 to rotate, and the rotation of the bidirectional screw 21 drives the two clamping rods 22 to move toward each other, so as to limit the left and right positions of the piston rod 10, in order to further When ensuring the stability of the piston rod 10, the staff member turns the knob 233, and the knob 233 drives the threaded rod 232 to move in the direction of the piston rod 10, thereby driving the arc clamping plate 231 to move in the direction of the piston rod 10. The two arc clamping plates 231 interact with each other to further fix the piston rod 10, and then adjust the position of the rotating rod 32 on the sliding frame 335, and fix it with the first bolt 337, and record the values ​​of the infrared rangefinder 31 and the distance sensor 37 at this time. At this time, the preparation work before the detection is completed, and then start the drive motor 334, and the drive motor 334 drives The rotating wheel 332 moves, thereby driving the rotating ring 331 to rotate on the annular groove of the base 11, and then driving the rotating rod 32 to move circumferentially around the piston rod 10, and judging the progress of the circumferential detection of the piston rod 10 through the information fed back by the distance sensor 37. When the distance subsequently measured by the distance sensor 37 is consistent with the initial distance, the circumferential detection of the piston rod 10 is completed, and then a signal is sent to the telescopic cylinder 323 to make it drop a certain distance, so that the grading plate 321 that loses support at the corresponding position pops out of the rotating rod 32 under the action of the connecting spring 322, and the connecting rod 34 is When the support of the grading plate 321 is lost, it will gradually move downward, and the above process will be repeated. When the infrared rangefinder 31 moves to the bottom, the radial detection of the piston rod 10 is completed; when the detection of the piston rod 10 is completed, the staff moves the synchronization rod 35, and makes the grading plate 321 in the synchronization rod 35 enter the rotating rod 32, and then starts the telescopic cylinder 323 again, so that the piston rod 10 of the telescopic cylinder 323 passes through the connecting hole 324 of the grading plate 321 again in sequence, and moves the synchronization rod 35 back to the initial position and fixes it with the second bolt 339, thereby completing the reset operation.

Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
