[0045] A production method of an automatic production line for embedded pipe segment parts, comprising the following steps:

[0046] S1. First, the pipe 3 is stacked and placed inside the collecting cavity 7. At the same time, the ring sheet 4 is placed inside the feeding rack 20 so that the center of the pipe 3 at the bottom of the collecting cavity 7 can be vertically aligned with the center of the ring sheet 4 at the bottom of the feeding rack 20;

[0047] S2, after that, the double-axis motor 24 can be started to drive the second gear 25 and the cam 23 to rotate. When the second gear 25 rotates, it can drive the first gear 19 and the winding wheel 18 to rotate, so that the connecting rope 12 can pull the displacement cross frame 10 to drive the push rod 11 to move inside the collecting chamber 7, and the pipe 3 at the bottom end of the collecting chamber 7 can be pushed outward to the inside of the ring piece 4. Subsequently, when the cam 23 rotates to contact the displacement rear frame 34, the support top plate 35 can be squeezed to drive the welding gun 26 to move to the intersection of the pipe 3 and the ring piece 4 to fit together, so that the pipe 3 and the ring piece 4 can be welded, and when the displacement rear frame 34 is displaced, it can contact the photoelectric sensor 28, start the drive motor 37 to drive the welding gun 26 to rotate, and the pipe 3 and the ring piece 4 can be annularly welded;

[0048] S3. Finally, when the cam 23 rotates to contact the second piston rod 32, it can drive the second piston rod 32 to enter the interior of the special-shaped gas cylinder 31, so that the first piston rod 30 can drive the connecting arm 15 to move toward the end away from the feed frame 20, so that the second receiving frame 16 and the first receiving frame 13 can be moved out from the bottom end of the pipe 3 and the ring piece 4, so that the welded pipe 3 and the ring piece 4 can fall down and be discharged, completing the work of precise butt welding of the pipe 3 and the ring piece 4.

[0049] The working principle of the embodiment 1 is as follows: when in use, a plurality of pipes 3 are first placed in the collecting cavity 7 in sequence, so that the pipes 3 can be stacked and placed in the collecting cavity 7, and at the same time, the pipe 3 at the bottom of the collecting cavity 7 can be horizontally aligned with the push rod 11, and then the ring piece 4 can be placed in the groove inside the feeding frame 20, so that the ring piece 4 can slide downward along the inside of the feeding frame 20 until it contacts the second receiving frame 16, so that the pipe 3 at the bottom of the collecting cavity 7 can be aligned with the axis of the ring piece 4 on the second receiving frame 16;

[0050] Subsequently, the dual-axis motor 24 can be started to drive the second gear 25 and the cam 23 to rotate. When the second gear 25 rotates, the first gear 19 and the winding wheel 18 can be driven to rotate. When the winding wheel 18 rotates, the connecting rope 12 can be pulled to drive the displacement cross frame 10 to move toward the inner front end of the collecting chamber 7, so that the push rod 11 can push the pipe 3 inside the collecting chamber 7 to move toward the front end. When the push rod 11 moves inside the collecting chamber 7, it can prevent the pipe 3 on the upper layer inside the collecting chamber 7 from falling downward. Subsequently, when the second gear 25 rotates to the position aligned with the first gear When the first gear 19 is out of contact, the reel 18 can drive the connecting rope 12 to pull the displacement cross frame 10 to move to the front end to the limit position, so that the pipe 3 passes through the first receiving frame 13 and is inserted into the inside of the ring sheet 4. Then, when the second gear 25 is out of mesh with the first gear 19, the elasticity of the first spring 9 will drive the push rod 11 and the displacement cross frame 10 to reset to the rear end, and when the push rod 11 moves to the rear end to the limit position, the front end of the push rod 11 can be vertically aligned with the rear end of the inner wall of the collection chamber 7, so that the pipe 3 in the upper layer of the collection chamber 7 will fall down for replenishment;

[0051] At the same time, when the second gear 25 is out of mesh with the first gear 19, the cam 23 will rotate to contact the displacement rear frame 34, so that the displacement rear frame 34 can be squeezed to move toward the rear end, and the displacement rear frame 34 is slidably sleeved on the guide rod 27, so that the displacement rear frame 34 can drive the support top plate 35 to move in a straight line. When the cam 23 squeezes the displacement rear frame 34 to move to the extreme position, the welding gun 26 can be driven to fit the junction of the pipe 3 and the ring sheet 4, and the welding machine 36 is kept in a normally open state, so that When the welding gun 26 contacts the pipe 3 and the ring piece 4, the pipe 3 and the ring piece 4 can be welded, and when the displacement rear frame 34 is displaced to the rear end to the limit position, it can also contact the photoelectric sensor 28, and the photoelectric sensor 28 is electrically connected to the drive motor 37, so that when the photoelectric sensor 28 senses a signal, the drive motor 37 can be turned on to drive the welding machine 36 to rotate as a whole, and the T-shaped key at the front end of the welding machine 36 rotates in the rotation groove inside the rear end of the support top plate 35, so that the welding machine 36 can be supported to rotate;

[0052] Subsequently, when the cam 23 rotates and passes through the surface of the displacement rear frame 34, the driving motor 37 can drive the welding machine 36 to rotate one circle, and the displacement rear frame 34 will also lose the extrusion of the cam 23, and the elasticity of the third spring 33 will drive the displacement rear frame 34 and the supporting top plate 35 to reset, so that the welding gun 26 can be disconnected from the pipe 3 and the ring sheet 4, and when the displacement rear frame 34 is disconnected from the photoelectric sensor 28, the photoelectric sensor 28 can lose the sensing signal, so that the driving motor 37 can be powered off, and then, when the cam 23 is continuously When the second piston rod 32 is rotated to contact, the second piston rod 32 can be squeezed to move toward the inside of the special-shaped gas cylinder 31, so that the first piston rod 30 can drive the connecting arm 15 to move toward the end away from the feeding frame 20, and the second receiving frame 16 is connected to the connecting arm 15, so that the connecting arm 15 can drive the second receiving frame 16 and the first receiving frame 13 to move outward synchronously, so that the pipe 3 and the ring piece 4 will lose the support of the first receiving frame 13 and the second receiving frame 16, and then the welded pipe 3 and the ring piece 4 will fall downward and be discharged;

[0053] The card slot at the top of the second receiving frame 16 slides on the card key at the bottom of the feed frame 20, so that the second receiving frame 16 can be supported to move in a straight line. Subsequently, when the cam 23 passes from the top of the second piston rod 32, the elasticity of the second spring 17 will drive the second receiving frame 16 and the first receiving frame 13 to move and reset, so that the first receiving frame 13 and the second receiving frame 16 can receive the pipe 3 and the ring piece 4 again. Moreover, when the second receiving frame 16 is reset, the first piston rod 30 can be driven by the connecting arm 15 to move toward the inside of the special-shaped gas cylinder 31, so that the second piston rod 32 can be reset upward, so that the cam 23 can pass through the second piston rod 32 again. By repeating the above steps, the pipe 3 and the ring piece 4 can be quickly aligned and plugged in. At the same time, annular welding can also be carried out to complete the automatic welding of the ring piece 4 and the pipe 3.

[0054] Example 2

[0055] On the basis of Example 1, Fig. 9 As shown, the feed rack 20 also includes a central cavity 38, an alignment push plate 39 and a cylinder 40. The central cavity 38 is fixedly installed at the top of the feed rack 20, the cylinder 40 is fixedly installed at the front end of the central cavity 38, and the alignment push plate 39 is fixedly installed at the rear end of the cylinder 40.

[0056] When implementing this embodiment, the ring piece 4 can be neatly placed inside the concentrated cavity 38, and a through hole is opened at the inner bottom end of the concentrated cavity 38 near the feed rack 20, and the thickness of the through hole is consistent with the thickness of the groove inside the feed rack 20. The cylinder 40 can be started to drive the alignment push plate 39 to move toward the inside of the concentrated cavity 38, so that when the alignment push plate 39 pushes the ring piece 4 to move to the extreme position, it can be vertically aligned with the through hole at the bottom end of the concentrated cavity 38, so that the ring piece 4 can slide through the through hole into the groove inside the feed rack 20, so that each time the cylinder 40 is turned on, it can push the alignment push plate 39 to drive a ring piece 4 into the interior of the feed rack 20 to complete the feeding work of the ring piece 4.
