At this time, the guide sleeve 34 can continue to move forward. When the guide sleeve 34 passes through the engaging portion 1 372 of the clamping plate 371 and contacts the engaging portion 2 373, under the action of the spring 374, the two ends of the strip groove 341 of the guide sleeve 34 are synchronously engaged by the engaging portion 1 372 and the engaging portion 2 373 of the clamping plate 371, thereby realizing automatic fixation of the guide sleeve 34.

[0019] The guide replacement mechanism 40 is arranged above the guide adjustment mechanism. The guide replacement mechanism 40 is used to replace the guide sleeve 34 on the guide adjustment mechanism that is worn due to corrosion. The guide replacement mechanism 40 includes an upper rack 41 and a lower rack 42. The upper rack 41 is arranged above the lower rack 42. The guide sleeve 34 waiting to be replaced is placed in the lower rack 42. The replaced guide sleeve 34 is placed on the upper rack 41.

A push plate 48 is fixedly installed on one side of the clamping jaw cylinder 47, and the bottom of the push plate 48 is arc-shaped. When the clamping jaw cylinder 47 moves downward to clamp the guide sleeve 34, the push plate 48 on one side of the clamping jaw cylinder 47 first contacts the top shafts 375 on the two fixing members 37. Under the action of the push plate 48, the two top shafts 375 slide in directions away from each other, thereby retracting the fixing member 37 into the slot 36, thereby releasing the guide sleeve 34. At this time, the guide sleeve 34 in the fixing slot 35 can be easily clamped by the clamping jaw cylinder 47. It should be further explained that the tool feeding mechanism 20 automatically switches the matching gun drill 24 according to the sizes of different deep holes to be processed, and at the same time, the guide adjustment mechanism 30 synchronously switches the guide sleeve 34 matching the gun drill 24 according to the switched gun drill 24, thereby realizing the synchronous adjustment of the gun drill 24 and the guide sleeve 34, and then realizing the processing of deep holes of different sizes of spacecraft accessories; at the same time, the guide replacement mechanism 40 is used to automatically replace the damaged guide sleeve 34 on the guide adjustment mechanism 30, without the need for downtime and reducing the risks brought by manual replacement.

A lifting frame 55 that can be raised and lowered is also provided on the feeding frame 51. 1 is provided with a driving cylinder for driving the lifting frame 55 to move, and the loading frame 51 is slidably installed on the machine tool 10. The movement of the loading frame 51 can be driven by a motor provided in the machine tool 10; when fixing the spacecraft accessories, the moving motor drives the moving lead screw 54 to rotate, and the moving lead screw 54 drives the two fixing claws 52 to move synchronously to fix the spacecraft accessories on the loading frame 51, which is convenient for subsequent deep hole processing operations. The lifting frame 55 that can be raised and the slidable loading frame 51 are used to realize deep hole processing operations at different positions of the spacecraft accessories.

[0021] Working principle: The spacecraft parts are fixed on the loading rack 51, and a gun drill 24 of matching size is selected according to the size of the hole to be drilled. The tool holder 21 is driven to rotate by the rotating motor so that the gun drill 24 moves to the top and is on the same axis as the through hole 32 of the axle box 31. At the same time, according to the size of the gun drill 24, the adjustment motor drives the adjustment plate 33 to rotate so that the guide sleeve 34 in the fixed groove 35 on the adjustment plate 33 that matches the gun drill 24 moves to the through hole 32 so that the guide sleeve 34 and the gun drill 24 are on the same axis; The hydraulic cylinder 29 drives the mounting seat 27 to slide on the base 28. At this time, the gun drill 24 is fed toward one side of the axle box 31, and passes through the guide sleeve 34 in the axle box 31 to contact the spacecraft accessories on one side. The driving motor 25 drives the gun drill 24 to rotate, so as to realize the deep hole drilling operation of the spacecraft accessories. When the guide sleeve 34 is damaged and needs to be replaced, the guide sleeve 34 that needs to be replaced is clamped by the clamping cylinder 47, and the pushing plate 48 on one side of the clamping cylinder 47 first contacts the top shafts 375 on the two fixing members 37. Under the action of the pushing plate 48, the two top shafts 375 slide in directions away from each other, thereby causing the fixing member 37 to retract into the slot 36, thereby releasing the guide sleeve 34, and the clamping cylinder 47 is driven by the rotating cylinder to rotate to the upper storage rack 41, and the damaged guide sleeve 34 is placed on the upper storage rack 41, and the guide sleeve 34 on the lower storage rack 42 is grasped by the clamping cylinder 47, and the clamping cylinder 47 is driven by the rotating cylinder to rotate to the slot 36 of the mixing plate 33, and the clamping part 1 372 and the clamping part 2 373 of the clamping plate 371 are clamped with the two ends of the strip groove 341 on the guide sleeve 34, and the guide sleeve 34 is automatically fixed under the action of the spring 374.
