[0028] See also Figure 1-5The utility model relates to a kind of CT machine shell processing drilling device, including pedestal 1, it is characterized by: pedestal 1 is provided with drilling device, drilling device includes drive assembly 2, drill bit 3 and pedestal 4, drive assembly 2 is installed on pedestal 1 top, pedestal 4 is set on pedestal 1 top, drill bit 3 is connected in the output end of drive assembly 2, pedestal 4 is provided with clamping device, clamping device includes clamping sleeve 5, clamping block 6, rotating sleeve 7, sliding sleeve 8, clamping rod 9, adaptive slot 10 and adaptive plate 11, clamping sleeve 5 is fixedly installed on pedestal 4, clamping block 6 is connected in adaptive plate 11 one side, rotating sleeve 7 is rotatably connected in clamping sleeve 5 one side, sliding sleeve 8 is movably connected with rotating sleeve 7 by screw thread, clamping rod 9 is slidably arranged in sliding sleeve 8, adaptive slot 10 is set in clamping sleeve 5, adaptive plate 11 is slidably arranged in adaptive slot 10, the outside of clamping sleeve 5 is provided with positioning mechanism, positioning mechanism includes let go slot 12, positioning sleeve 13, limiting rod 14, limiting sleeve 15, conical spring 16, positioning rod 17 and positioning slot 18, let go slot 12 is set on limiting sleeve 15, positioning sleeve 13 is slidably arranged in the outside of clamping sleeve 5, limiting rod 14 is connected in positioning rod 17 one side, limiting sleeve 15 is rotatably arranged in the outside of clamping sleeve 5, positioning rod 17 one end is connected with the outer wall of rotating sleeve 7 by conical spring 16, and the other end of positioning rod 17 is inserted into positioning slot 18, and multiple positioning slots 18 are set in the outside of clamping sleeve 5.

[0029] Fixed plate 19 is fixedly arranged in clamping sleeve 5, and pulling spring 20 is connected on the side of fixed plate 19, and the other end of pulling spring 20 is connected with one end of clamping rod 9.

[0030] Push spring 21 is sleeved on the outside of limiting rod 14, and push spring 21 is connected in positioning sleeve 13 side, and the other end of push spring 21 is contact type connection with limiting sleeve 15.

[0031] Connecting block 22 is connected on the side of clamping block 6, and connecting slot 23 is correspondingly set on sliding sleeve 8, and connecting slot 23 is matched with connecting block 22.

[0032] Rubber strip 24 is connected on the outside of limiting sleeve 15.

[0033] In the embodiment, before the CT machine shell needs to be drilled, first rotate the limiting sleeve 15 to drive the limiting sleeve 15 to move the limiting slot 12. When the limiting slot 12 moves to the position corresponding to the limiting rod 14, push the positioning sleeve 13, the positioning sleeve 13 drives the limiting rod 14 to slide and make the limiting rod 14 pass through the limiting slot 12. At the same time, the positioning sleeve 13 cooperates with the limiting sleeve 15 to extrude the push spring 21 sleeved outside the limiting rod 14. When the push spring 21 is extruded to the limit, the positioning sleeve 13 will no longer limit the outside of the positioning rod 17. Then rotate the rotating sleeve 7 to drive the positioning rod 17 to rotate. Because the end of the positioning rod 17 and the edge of the positioning slot 18 are chamfered, the side wall of the positioning slot 18 extrudes the end of the positioning rod 17, so that one end of the positioning rod 17 slides out of the positioning slot 18, and the other end of the positioning rod 17 drives the conical spring 16 to stretch. Because the inner wall of the rotating sleeve 7 and the outer wall of the sliding sleeve 8 are movably connected through threads, the sliding sleeve 8 drives the clamping block 6 to move through the cooperation of the connecting slot 23 and the connecting block 22. The clamping block 6 drives the adapter plate 11 to slide along the adapter slot 10. Because the adapter plate 11 and the adapter slot 10 are both designed as inclined structures, when the adapter plate 11 slides along the adapter slot 10, the clamping block 6 spreads outward, and then the clamping block 6 drives the other side of the connecting block 22 to slide along the connecting slot 23. The clamping block 6 no longer clamps the side wall of the clamping rod 9. Then place the CT machine shell on the pedestal 4, and make each end of the clamping rod 9 abut against the outside of the CT machine shell. Then each clamping rod 9 slides along the sliding sleeve 8 to different degrees, and the other end of each clamping rod 9 drives the pull spring 20 to stretch to different degrees. After each end of the clamping rod 9 abuts against the outside of the CT machine shell, rotate the rotating sleeve 7 in the opposite direction. The rotating sleeve 7 drives the positioning rod 17 to move again, and the sliding sleeve 8 pushes the clamping block 6 to slide and reset. Then the clamping block 6 drives the adapter plate 11 to slide and reset along the adapter slot 10. Then the adapter plate 11 drives the clamping block 6 to gather inward, and the clamping block 6 drives the other side of the connecting block 22 to slide along the connecting slot 23. When the clamping block 6 clamps the outer wall of the clamping rod 9 again, stop rotating the rotating sleeve 7. At this time, the conical spring 16 drives the positioning rod 17 to engage into the original positioning slot 18. Then release the positioning sleeve 13, the push spring 21 drives the positioning sleeve 13 to slide and reset, and the positioning sleeve 13 drives the limiting rod 14 to slide and reset. When the push spring 21 is completely reset, rotate the limiting sleeve 15 again to drive the limiting sleeve 15 to move to the position not corresponding to the limiting rod 14, so that the limiting rod 14 cooperates with the limiting sleeve 15 to limit the positioning sleeve 13. The positioning sleeve 13 limits the outer end of the positioning rod 17 to prevent the positioning rod 17 from moving. The positioning rod 17 cooperates with the positioning slot 18 to limit the rotating sleeve 7 to prevent the rotating sleeve 7 from rotating, thereby ensuring the stability of the clamping device and the stable clamping of the outside of the CT machine shell.

[0034] Referring to Figure 1-2 As a further embodiment of the device as a whole: the first motor 25 is arranged on the base 1, the first lead screw 26 is connected at the output end of the first motor 25, the movable seat 27 is arranged below the pedestal 4, the first lead screw 26 is rotatably installed on the movable seat 27, and the movable seat 27 is movably connected with the first lead screw 26 through threads below.

Then the pedestal 4 will drive the CT machine shell arranged above to move longitudinally, and after moving to the appropriate position, the first motor 25 is turned off. If the position of the CT machine shell does not need to be moved any more, the drive assembly 2 is turned on again to drill. If the appropriate position has not been reached, the second motor 28 can be turned on according to actual needs, so that the second motor 28 drives the second lead screw 29 to rotate, and then the movable seat 27 will move along the second lead screw 29, and the movable seat 27 will drive the pedestal 4 installed above to slide along the slide rod 32, and at the same time, the first motor 25 and the sliding frame 31 will slide along the slide rail 30.
