[0027] The present invention will be further described below in conjunction with the embodiments.

[0028] Example: Reference Figure 1-Figure 5A connecting rod blank measuring device includes a base 1 and a clamping assembly, including two sliding frames 2 slidably mounted on the base 1, a plurality of telescopic rods 3 are connected between the two sliding frames 2, a reset spring is connected between the two sliding frames 2, a mounting groove 10 is provided on the two sliding frames 2, and a carrier 5 is movably installed in the two mounting grooves 10, a sliding frame is provided on the base 1, the sliding frame 2 is slidably mounted on the sliding frame, the sliding frame 2 is provided with a mounting groove 10, the carrier 5 is slidably installed in the mounting groove 10, a mounting rod 11 is fixedly installed on the bottom wall of the carrier 5, and a Material 4, a carrier 5 is slidably mounted with a clamping plate 9, a slide groove 8 is opened on the carrier 5, a slide rod 7 is slidably mounted in the slide groove 8, the clamping plate 9 is fixedly mounted on the top of the slide rod 7, a first piston tube 17 is fixedly mounted on the inner wall of the mounting groove 10, a first piston rod is movably inserted on the first piston tube 17, the first piston rod is fixedly connected to the slide rod 7, a first mounting plate 12 is fixedly mounted on the mounting rod 11, a first airbag 15 is arranged on the bottom wall of the first mounting plate 12, and the first airbag 15 and the first piston tube 17 are connected; a detection component includes an infrared rangefinder 6 fixedly mounted on the carrier 5.

[0029] The material 4 (i.e. the connecting rod blank) is placed on two carriers 5. Under the action of the gravity of the material 4, the carriers 5 are pressed down along the mounting groove 10. The carriers 5 drive the mounting rod 11 to move down. The mounting rod 11 drives the first mounting plate 12 to move down and squeeze the first airbag 15. The air in the first airbag 15 enters the multiple first piston tubes 17. Under the action of air pressure, the first piston rod moves into the first piston tube 17. The first piston rod drives the multiple slide bars 7 away from the center of the slide frame 2, thereby driving the multiple clamping plates 9 to move away from the center of the slide frame 2 synchronously, so that the clamping plates 9 squeeze the inner walls of the two ring openings of the connecting rod blank to complete the clamping. Through the above clamping, the clamping force of the clamping plates in each ring opening on the inner wall can be the same, so that the center of the two ring openings is kept coincident with the position of the two infrared rangefinders 6. The center point of the connecting rod blank is measured by the rapid measurement of the infrared rangefinder 6, which not only improves the measurement accuracy but also improves the measurement efficiency.

A blowing frame 22 is provided at one end of the cleaning frame 20, and a plurality of air nozzles are provided on the blowing frame 22.

[0031] When the mounting rod 11 moves downward, the second airbag 16 will be squeezed through the second mounting plate 14, and the air in the second airbag 16 will enter the second piston tube 25. Under the action of air pressure, the second piston rod 26 moves into the second piston tube 25, and the second piston rod 26 drives the transmission plate 24 to move, and the transmission plate 24 drives the rack 23 to slide. During the sliding process of the rack 23, it will mesh with the gear ring 18. During the rotation of the gear ring 18, it will drive the rotating rod 19 to move. The rotating rod 19 drives the cleaning frame 20, the cleaning block 21 and the blowing frame 22 to slide along the outer wall of the ring mouth of the connecting rod blank to clean the outer wall of the ring mouth to prevent impurities outside the blank from affecting the clamping effect of the clamping plate 9, thereby improving the positioning accuracy and ensuring the detection accuracy.

[0032] In addition, during the sliding of the second piston rod 26 , the air at the other end of the second piston tube 25 enters the blowing rack 22 through the second connecting tube 28 , and blows away the cleaned impurities, thereby improving the cleaning effect.

[0033] A hinge is used between the cleaning frame 20 and the rotating rod 19 to facilitate the placement of the connecting rod blank. In addition, the second connecting pipe 28 is a hose, which further facilitates the placement and removal of the connecting rod blank.
