The tool for boring holes in a compressor cylinder block includes a support platform 1, and two transmission structures 4 are installed below the support platform 1. The two transmission structures 4 are vertically and staggered with each other up and down. Both ends of the two transmission structures 4 are connected with worms 2, and one side of the worm 2 is meshed with a worm wheel 3. The worm 2 is rotatably connected to the support platform 1. The transmission structure 4 includes a long shaft 41, two lower bevel gears 42 and two upper bevel gears 43. The two upper bevel gears 43 are respectively meshed with the two lower bevel gears 42. The two lower bevel gears 42 are respectively fixedly sleeved on the two ends of the long shaft 41, and the long shaft 41 is rotatably connected to the bottom surface of the support platform 1. The upper bevel gear 43 is fixedly sleeved on the lower end of the adjacent worm 2.

[0026] The outer surface of the worm wheel 3 is rotatably sleeved with a vertical plate 7, and the vertical plate 7 is fixed to the support platform 1. A prism 13 is slidably inserted at the axis of the worm wheel 3. The end of the prism 13 close to the axis of the support platform 1 is slidably sleeved with a threaded rod 5, and the other end of the threaded rod 5 is rotatably sleeved with a clamping plate 18. The cylinder body is placed between the four clamping plates 18. The outer surface of the threaded rod 5 is threadedly sleeved with a threaded tube 6, and the other end of the threaded tube 6 is rotatably sleeved on the outer surface of the prism 13. A tension spring 10 is fixed to one end of the vertical plate 7 close to the threaded tube 6, and the other end of the tension spring 10 is fixedly sleeved on the outer surface of the threaded tube 6. A circular ring 8 is arranged above the support platform 1. Four threaded tubes 6 are distributed in a circular array around the axis of the circular ring 8. The threaded tube 6 is connected to the prism 13 and the connected The threaded rod 5 is coaxially arranged, and the connection between the threaded tube 6 and the prism 13 is a circular hole-shaped structure. The outer surface of the prism 13 is tangent to the inner wall of the circular hole-shaped structure of the threaded tube 6. The ring 8 is located above the threaded tube 6. The prism 13 can rotate relatively while sliding inside the threaded tube 6. When the long shaft 41 rotates, the two connected lower bevel gears 42 are engaged with the upper bevel gear 43, driving the two prisms 13 above to rotate synchronously, so that the two threaded rods 5 on a straight line rotate synchronously and engage with the corresponding threaded tubes 6, pushing the two clamps 18 on a straight line to move the same distance, ensuring that when the two adjusted clamps 18 are close to each other to clamp the cylinder body, the center position of the cylinder body can coincide with the center position of the support platform 1.

[0027] A bent rod 9 is fixed to one end of the upper surface of the threaded tube 6 away from the tension spring 10, and a reducing arc plate 11 is provided on the side of the bent rod 9 away from the axis of the support platform 1.

Both ends of the reducing arc plate 11 are arc-shaped, and the arc radii at both ends of the reducing arc plate 11 are different. The connection between the two ends of the reducing arc plate 11 is an inclined surface. When the bent rod 9 moves from the small diameter end to the large diameter end of the reducing arc plate 11, the bent rod 9 pushes the clamping plate 18 close to the cylinder body through the threaded tube 6 and the threaded rod 5. The reducing arc plate 11 is fixed to the inner ring surface of the circular ring 8, and the outer ring surface of the circular ring 8 is rotatably sleeved with a clamping plate 12.

A motor 16 is fixed to the upper surface of the support platform 1, and the active bevel gear 15 is fixed to the output end of the motor 16. The motor 16 drives the active bevel gear 15 to mesh with the conical tooth groove 14 to drive the ring 8 to rotate.

[0029] During use, the rotating long shaft 41 drives the two connected lower bevel gears 42 to rotate, and the lower bevel gear 42 drives the two connected worm gears 2 to rotate by meshing with the upper bevel gear 43. The two worm wheels 3 meshing with the two worm gears 2 drive the two rib rods 13 synchronously, and the rib rod 13 drives the connected threaded rod 5 to rotate and mesh with the threaded cylinder 6, changing the initial distance between the connected clamping plates 18 and the threaded cylinder 6, so that the two clamping plates 18 on a straight line move the same distance, and the cylinder body is placed between the four clamping plates 18, and the starting motor 16 drives the active bevel gear 15 to mesh with the conical tooth groove 14, driving the circular ring 8 to rotate, and the circular ring 8 drives the four reducing arc plates 11 to rotate synchronously, and the bent rod 9 moves from the large diameter circular arc end of the reducing arc plate 11 to the small diameter end of the reducing arc plate 11, and pushes the four clamping plates 18 to clamp the cylinder body at the same time through the threaded cylinder 6 and the threaded rod 5. During the reciprocating rotation of the circular ring 8, the cylinder body of the same specification is quickly clamped and fixed.
