[0045] Working principle, when in use: the aircraft engine turbine is sleeved on the outside of the operating compartment 12, and after sleeved, the threaded operating rod 13 is rotated to drive the linkage plate 14 to move, and the movement of the linkage plate 14 drives the traction plate 15 to extend and contract, and the extension of the traction plate 15 drives the arc clamping plate 16 to move, and the aircraft engine turbine is internally clamped and fixed by the movement of the arc clamping plate 16. After clamping and fixing, the drive motor 34 is started to drive the third gear 35 to rotate through the output shaft, and the rotation of the third gear 35 is meshed with the gear column 37 for transmission, and the rotation of the gear column 37 drives the control rod 36 to rotate, and the rotation of the control rod 36 drives the first transmission gear 38 and the second transmission gear 39 to rotate synchronously respectively. When the aircraft engine turbine is conveyed, the push rod motor 45 is started to drive the control plate 46 to retract and move, and the control rod 36 is driven to move in the opposite direction through the retraction movement of the control plate 46. The reverse direction of the control rod 36 The movement causes the first transmission gear 38 to mesh with the first driven gear 40 for transmission. The rotation of the first driven gear 40 drives the rotation of the first threaded rod 2. The rotation of the first threaded rod 2 drives the first moving block 3 to move, and at the same time drives the linkage frame 4 to move. The movement of the linkage frame 4 drives the second threaded rod 9 and the limit rod 11 to move synchronously. The movement of the linkage frame 4 drives the aircraft engine turbine to move and transport. When the second threaded rod 9 moves, the first gear 8 meshes with the rack 33 for transmission, thereby driving the first linkage sleeve 7 to rotate. The rotation of the first linkage sleeve 7 drives the second threaded rod 9 to move, and at the same time drives the support plate 10 to move upward smoothly through the limit rod 11. The upward movement of the support plate 10 causes the aircraft engine turbine to move upward, so that the aircraft engine turbine enters the interior of the body 1 through the through port. After entering, the through port is closed by the cover plate 47, and the drive motor 34 stops working at the same time.
[0046] After the inspection object enters the machine body 1, the push rod motor 45 is started again, driving the control rod 36 to move forward, and at the same time, the second transmission gear 39 is meshed with the second driven gear 42. The second driven gear 42 rotates to drive the transmission rod 41 to rotate synchronously, and at the same time drives the second pulley 43 to rotate. The rotation of the second pulley 43 drives the rotation of the double pulley 30 through the second belt 44, and at the same time drives the rotation of the first pulley 31 through the first belt 32. The rotation of the first pulley 31 drives the rotation of the linkage rod 29, and the rotation of the double pulley 30 drives the rotation of the reciprocating screw 18. The rotation of the reciprocating screw 18 drives the second moving block 19 to move, and at the same time drives the mounting ring 21 to move through the balance ring 23. The movement of the balance ring 23 synchronously drives the second linkage sleeve 26 to move, and the lateral movement of the mounting ring 21 performs lateral surface defect detection on the object to be inspected;
[0047] The rotation of the linkage rod 29 drives the second linkage sleeve 26 to rotate, the rotation of the second linkage sleeve 26 drives the second gear 28 to rotate synchronously, the rotation of the second gear 28 drives the gear ring 27 to rotate synchronously, the rotation of the gear ring 27 drives the mounting ring 21 to rotate in a circle, and the circular motion of the mounting ring 21 is used to perform circular detection on the object to be detected.
