[0026] As Figure 7 , the guiding device 3 includes a positioning chassis 40, a driving motor 41, a lead screw 42, and a first limiting frame 43. The driving motor 41 is fixedly installed at the front end of the positioning chassis 40. The lead screw 42 is fixedly installed at the center of the rear end of the driving motor 41. The first limiting frame 43 is symmetrically and fixedly installed at the front end of the top of the positioning chassis 40. By driving the lead screw 42 to rotate forward and backward by the driving motor 41, the displacement support plate 29 can be displaced forward and backward.

[0027] The first rack 8 meshes with the top end of the transmission gear 15, the second rack 14 meshes with the transmission gear 15, the connecting rod 9 is slidably sleeved on the outer ring of the extension rod 16, the support bottom plate 19 is fixedly installed at the front end of the top of the positioning chassis 40, the displacement support plate 29 is threadedly sleeved on the outer ring of the lead screw 42, the rear end surface of the first limiting frame 43 is inclined at 45°, the first limiting frame 43 is horizontally aligned with the contact bottom plate 33, an activity groove is provided at the inner center of the positioning chassis 40, and the lead screw 42 is vertically aligned with the activity groove, the magnetic sheet 39 is horizontally aligned with the iron sheet 13, the front end and the rear end of the contact bottom plate 33 close to the temporary storage base 38 are both arranged in an arc state, clamping keys are symmetrically fixedly installed on the side end of the displacement wing plate 37 away from the displacement wing plate 37, and clamping grooves are symmetrically provided inside the side end of the support side frame 34 close to the temporary storage base 38, a bolt is threadedly inserted into the side end of the displacement wing plate 37, there is a distance of a short pipe 12 between the bottom end of the material guiding cavity 23 and the inner bottom end of the support bottom plate 19, the top ends of the counterweight plate 11 and the push plate 6 are respectively flush with the bottom end of the material guiding cavity 23, the inside of the L-shaped air cylinder 22 is in a hollow state, and a sealed cavity is formed between the first piston rod 18, the second piston rod 21 and the L-shaped air cylinder 22, the first piston rod 18 is horizontally aligned with the rear end of the counterweight plate 11, and a vertical groove is provided at the inner center of the material guiding cavity 23.

[0028] The working principle of Embodiment 1 is as follows: During use, first stack the short tubes 12 into the inside of the feeding cavity 23 in sequence, and then install and sleeve the round hole of the external flange on the positioning pins 36, so that the flange can be restricted between the two positioning pins 36. At the same time, the key on the side end of the displacement wing plate 37 can move in the slot inside the side end of the support side frame 34, so that the distance between the two positioning pins 36 can be adjusted, and thus the positioning pins 36 can be adapted to support flanges of different sizes. Subsequently, bolts are installed on the displacement wing plate 37. When the displacement wing plate 37 is adjusted to the specified position, the bolts can be screwed to be fastened to the support side frame 34 to complete the restriction work of the displacement wing plate 37. Then, the drive motor 41 can be started to drive the lead screw 42 to rotate clockwise. Since the displacement support plate 29 is threadedly sleeved on the outer ring of the lead screw 42, the displacement support plate 29 can displace forward. By moving the displacement support plate 29 in the moving slot at the center inside the positioning chassis 40, it can be ensured that the displacement support plate 29 displaces in a straight line. At this time, when the displacement support plate 29 displaces forward, it can drive the contact bottom plate 33 to contact the first limiting frame 43. Since the front surface of the first limiting frame 43 is inclined at 45°, the contact bottom plate 33 drives the support side frame 34 to displace along the surface of the first limiting frame 43 towards the end away from the displacement support plate 29, so as to expand the distance between the two flanges. At the same time, by sliding and inserting the movable rod 31 into the inside of the positioning cavity 30, the support chassis 32 can be moved in a straight line to prevent the chassis 32 from tilting. Subsequently, when the displacement support plate 29 continues to displace, it can drive the magnetic sheet 39 to squeeze the iron sheet 13 and the second rack 14 to displace forward. At this time, when the second rack 14 displaces forward, it can drive the transmission gear 15 to rotate. When the transmission gear 15 rotates, it can drive the first rack 8 to displace backward. Thus, the first rack 8 can drive the counterweight plate 11 to displace backward through the connecting rod 9. At this time, the counterweight plate 11 can displace backward. At this time, when the counterweight plate 11 maintains its normal state, there is a gap between the push plate 6 and the counterweight plate 11. When the connecting rod 9 drives the counterweight plate 11 to displace backward, the counterweight plate 11 will not directly contact the push plate 6. At this time, when the counterweight plate 11 displaces backward, the counterweight plate 11 can be separated from contact with the first piston rod 18. At this time, the elasticity of the second spring 26 will pull the restricted rear frame 27 to displace upward, so as to facilitate the removal of the short tube 12 from between the feeding cavity 23 and the support bottom plate 19. When the restricted rear frame 27 displaces upward, it can drive the second piston rod 21 to move upward and reset through the special-shaped bracket 17, so that the first piston rod 18 can displace forward and reset. Subsequently, when the connecting rod 9 drives the counterweight plate 11 to contact the push plate 6, the counterweight plate 11 can squeeze the push plate 6 to displace backward, so that the push plate 6 can push the short tube 12 out from the bottom end of the feeding cavity 23. At the same time, the displacement support plate 29 can drive the temporary storage base frame 38 to move to be vertically aligned with the bottom of the rear end of the support bottom plate 19, so that the short tube 12 can accurately fall into the inside of the temporary storage base frame 38.The flange on the displacement wing plate 37 can be horizontally aligned with the short tube 12 inside the temporary storage base frame 38. Subsequently, the driving motor 41 can be turned on again to drive the screw rod 42 to rotate counterclockwise, so that the displacement support plate 29 can be displaced to the rear end. At this time, the displacement support plate 29 can drive the magnetic suction sheet 39 to displace to the rear end. The magnetic suction sheet 39 is adsorbed and fitted with the iron sheet 13. When the magnetic suction sheet 39 is displaced, the second rack 14 can be driven to displace to the rear end through the iron sheet 13, so that the second rack 14 can drive the transmission gear 15 to rotate again, causing the first rack 8 to drive the counterweight plate 11 to displace to the front end, so that the push plate 6 and the counterweight plate 11 can be displaced to the front end. At this time, when the push plate 6 moves to the front end to the limit position, the blocking of the limiting front frame 20 can prevent the push plate 6 from continuing to displace, and when the front end of the push plate 6 is fitted with the rear end surface of the limiting front frame 20, the short tube 12 on the upper layer inside the guide cavity 23 can fall downward to the supporting bottom plate 1 9, the filling of the short tube 12 is completed. Subsequently, the setting of the first spring 7 allows the counterweight plate 11 to continue to move toward the front end, so that the counterweight plate 11 can squeeze the first piston rod 18 into the interior of the L-shaped air cylinder 22, driving the second piston rod 21 to move downward. When the second piston rod 21 moves downward, the special-shaped bracket 17 can drive the limiting rear frame 27 to move downward at the same time, so that the limiting rear frame 27 can close the rear end of the guide cavity 23 to prevent the short tube 12 on the supporting bottom plate 19 from rolling out, and the filling of the short tube 12 is completed. Subsequently, when the displacement support plate 29 continues to move toward the rear end, it can drive the contact bottom plate 33 to disengage from the first limiting frame 43. At this time, the elasticity of the third spring 28 will pull the chassis 32 toward the center of the displacement support plate 29, so that the displacement wing plate 37 can drive the flange to dock with the short tube 12 on the temporary storage base frame 38, and complete the alignment and splicing of the two flanges and the short tube 12.

[0029] Example 2 On the basis of Example 1, Figure 8 As shown, the positioning chassis 40 further includes a second limiting frame 44 and an extending top frame 45 . The extending top frame 45 is fixedly mounted at the rear end of the positioning chassis 40 , and the second limiting frame 44 is symmetrically fixedly mounted at the top end of the extending top frame 45 .

[0030] When implementing this embodiment, when the displacement support plate 29 moves to the rear end to the extreme position, the rear end of the contact base plate 33 can contact the front end of the second limiting frame 44. The front end of the second limiting frame 44 is inclined at 45°, so that when the contact base plate 33 moves to the rear end, the contact base plate 33 can be displaced along the surface of the second limiting frame 44 away from the inner center of the positioning chassis 40, so that the contact base plate 33 can drive the supporting side frame 34 to move to the side end again, so as to facilitate the removal of the welded flange and the short pipe 12 to complete the work.
