When feeding, the conveying motor is started to drive the driving roller 54 to rotate. When the driving roller 54 rotates, it drives the pipeline 5 at the bottom to move rightward under the action of friction force, and continuously feeds the pipeline 5.

[0030] The two ends of the driving roller 54 are slidably connected to the inner walls of the front and rear sides of the housing, and a push rod 56 is connected between the pushing block 53 and the conveying motor, and the two ends of the pushing rod 56 are respectively rotatably connected to the pushing block 53 and the conveying motor. When the pushing block 53 moves to the left, it drives the pushing rod 56 rotatably connected thereto to rotate upward, driving the feeding motor on the top of the pushing rod 56 to slide upward, so that the driving roller 54 moves upward and separates from the pipe 5, so that the pipe 5 remains stationary during the drilling process. When the drilling is completed and the pushing block 53 moves to the right, the driving roller 54 is reset accordingly, contacts the pipe 5 again, and conveys the pipe 5, so that the synchronous conveying of the pipe 5 can be achieved, and the drilling efficiency is fully improved while the drilling accuracy is ensured.

[0031] Working principle: when punching holes, the rotating motor is started, so that the rotating disk 22 starts to rotate, and when the rotating disk 22 rotates, the rotating rod 21 on the edge rotates accordingly, and when the rotating rod 21 rotates, it drives the driving rod 20 to move left and right periodically in the horizontal direction, and when the driving rod 20 moves, it drives the driving motor 14 to move accordingly. At this time, the driving motor 14 is started, so that the driving shaft 15 starts to rotate while moving left and right. When the driving shaft 15 moves, it drives the slider 13 to slide in the slide groove 12. When the slider 13 moves, it drives the movable seat 18 to move accordingly. When the driving shaft 15 rotates, it drives the first driving bevel gear at the top The wheel 16 starts to rotate, and when the first driving bevel gear 16 rotates, it drives the first driven bevel gear 17 meshing therewith to start rotating, so that the connecting shaft starts to rotate. When the connecting shaft rotates, it drives the driving gear 19 to rotate accordingly. When the driving gear 19 rotates, it drives the driven gear 37 meshing therewith to start rotating. When the driven gear 37 rotates, it drives the rotating cylinder 36 to start rotating. When the rotating cylinder 36 rotates, it drives the inner sleeve 41 slidably connected to its left end to start rotating. When the inner sleeve 41 rotates, it drives the second driving bevel gear 43 to start rotating, so that the second driven bevel gear 29 meshing therewith starts rotating, and the first When the second driven bevel gear 29 rotates, the rotating sleeve 28 is driven to rotate accordingly. When the rotating sleeve 28 rotates, the movable pin 30 inside is driven to start rotating. When the movable pin 30 rotates, the drill bit 44 at its inner end is driven to start rotating. When the movable seat 18 moves to the left, the driving gear 19 is driven to move to the left accordingly. When the driving gear 19 moves to the left, it drives the driven gear 37 and the rotating cylinder 36 to move to the left through the baffle. When the rotating cylinder 36 moves to the left, it drives the outer ring 38 and the folding rod 39 of the outer wall to move to the left, and applies a leftward thrust to the outer sleeve 35, so that the outer sleeve 35 and the tapered cylinder 33 move to the left. When the conical cylinder 33 moves to the left, the inclined groove 34 on its inner wall slides with the sliding ball 31, pushing the sliding ball 31 to start moving in the direction of the pipe 5, driving the movable pin 30 connected to the inner side of the sliding ball 31 to move accordingly, so that the drill bit 44 moves toward the outer wall of the pipe 5 while rotating, and multi-station synchronous drilling is performed on the pipe 5. At this time, the spring 32 is compressed to generate an elastic force in the opposite direction. When the movable seat 18 moves in the opposite direction, the drill bit 44 is reset under the action of the spring 32. Through the above steps, the synchronization of the pipe 5 during drilling can be guaranteed, and the drilling efficiency and accuracy can be improved.

[0032] When the driving rod 20 moves to the left, it drives the vertical rod 23 and the bottom cross bar 24 to move to the left, so that the first transmission rod 25 connected to the upper part of the cross bar 24 moves to the left accordingly. When the first transmission rod 25 moves to the left, it drives the top rack 45 to move to the left, so that the transmission gear 46 meshing with the top of the rack 45 starts to rotate. When the transmission gear 46 rotates, it drives the third driven bevel gear 47 to rotate through the gear shaft. When the third driven bevel gear 47 rotates, it drives the rotating ring 48 meshing with it to start rotating, so that the arc groove 50 on the surface of the rotating ring 48 starts to rotate. When the arc groove 50 rotates, the sliding rod slidably connected to the inside thereof slides relatively, driving the sliding rod to start moving in the direction of the pipeline 5. When the sliding rod moves, it drives the positioning block 51 to move accordingly. When the positioning block 51 moves, it drives the clamping block 52 to start moving synchronously, and the pipeline 5 is clamped for centering while drilling, so as to ensure the concentricity of the pipeline 5 in the multi-station continuous drilling mechanism, and to prevent the pipeline 5 from rotating or deflecting during drilling, which affects the drilling accuracy.

[0033] When the cross bar 24 moves to the left, it drives the second transmission rod 26 to move accordingly, so that the second transmission rod 26 slides to the left in the bottom groove. When the second transmission rod 26 moves to the left, it drives the push block 53 to move to the left. When feeding, the conveying motor is started to drive the driving roller 54 to rotate accordingly. When the driving roller 54 rotates, it drives the bottom pipe 5 to move to the right under the action of friction, and continuously feeds the pipe 5. When the push block 53 moves to the left, it drives the push rod 56 rotatably connected thereto to rotate upward, and drives the feeding motor at the top of the push rod 56 to slide upward, so that the driving roller 54 moves upward and disengages from the pipe 5, so that the pipe 5 remains stationary during the drilling process. When the drilling is completed, the push block 53 moves to the right, and the driving roller 54 is reset accordingly, contacts with the pipe 5 again, and conveys the pipe 5, thereby realizing synchronous conveying of the pipe 5, and fully improving the drilling efficiency while ensuring the drilling accuracy.
