[0037] The second slider 541 is a rectangular structure, and the bottom of the second slider 541 is in transmission connection with the output end of the electric sliding table 53. One side outer wall of the second slider 541 is fixedly connected with a flaw detector 542. The outer wall of the second slider 541 and the side away from the flaw detector 542 are provided with a guide cavity 543. The inner wall of the guide cavity 543 and the side close to the flaw detector 542 are fixedly connected with a second motor 544.

When the top of the second vertical plate 25 is at the same level as the top of the first vertical plate 23, it is used for limiting the engine cylinder body 3 before assembly and clamping. When the top of the second vertical plate 25 is at the same level as the first sliding groove 12, it is used for the two-sided linkage assembly 5 to extend to the inner wall of the piston cavity of the engine cylinder body 3; The output end of the third motor drives the second screw rod 548 to rotate, so that the linkage block 549 drives the outer wall of the hollow cylinder 5412 to be connected to the inner wall of the piston cavity of the engine cylinder body 3, and the second motor 544 drives the linkage disc 545 to rotate, so that the outer wall of the hollow cylinder 5412 rotates around the output end of the second motor 544; The hollow cylinder 5412 rotates while driving the distance measuring sensor 5410, so that its signal output end irradiates the inner wall of the guide cavity 543. By detecting the distance between the signal output end of the distance measuring sensor 5410 and the guide cavity 543, and continuously rotating the hollow cylinder 5412 to be connected to the inner wall of the guide cavity 543, the third motor can continuously drive the second screw rod 548, so that the hollow cylinder 5412 is always in a state of sealing and rolling fit with the inner wall of the piston cavity of the engine cylinder body 3. If the position of the hollow cylinder 5412 changes, the distance between the signal output end of the distance measuring sensor 5410 irradiating the inner wall of the guide cavity 543 also changes, and the signal is transmitted to the controller, so that the controller transmits the measured distance signal of the distance measuring sensor 5410 to the display screen, providing the inner diameter error detection function for the inner wall data of the piston cavity of the engine cylinder body 3; The output end of the fourth electric push rod 5411 drives the ultrasonic flaw detector probe 5413, so that the hollow cylinder 5412 and the ultrasonic flaw detector probe 5413 move to different positions of the inner wall of the piston cavity of the engine cylinder body 3, and the inner diameter error degree and whether the inner wall has cracks or defects at different positions of the inner wall of the piston cavity of the engine cylinder body 3 are detected, and the detected data is transmitted to the flaw detector 542 through the ultrasonic flaw detector probe 5413, so as to detect the inner diameter error degree and whether the inner wall has cracks or defects at different positions of the inner wall of the piston cavity of the engine cylinder body 3; By the magnetic ring at the end of the two groups of hollow cylinders 5412, the two groups of hollow cylinders 5412 can be close to each other, and at the same time, the two groups of hollow cylinders 5412 and the ultrasonic flaw detector 5413 can be rotated synchronously, which can improve the efficiency of the inner diameter error degree of different positions in the piston cavity of the engine cylinder 3 and whether the inner wall has cracks or defects.
