The two moving platforms of the bidirectional moving mechanism 3 are fixedly connected to a sliding platform 11, and both sliding platforms 11 are provided with a feeding guide assembly. Part 5, the feeding guide rail assembly 5 includes a fixed guide rail 501 and an adjusting guide rail 502, the adjusting guide rail 502 is slidably connected to the sliding table 11, and an S-shaped channel is formed between the fixed guide rail 501 and the adjusting guide rail 502. The main machine base 1 is located below the quick-release feeding turntable 4 and is fixedly connected to a loosening cylinder 6. The piston rod of the loosening cylinder 6 is fixedly connected to a push fork 601. The two sliding tables 11 are respectively fixedly provided with a pipe rotation assembly 7 and a pipe tightening assembly 8. The main machine base 1 is fixedly connected to a laser welder 9.

[0027] The feeding rotating assembly 2 includes a stepping motor and a rotating shaft. The stepping motor drives the rotating shaft to rotate, thereby driving the quick-release feeding turntable 4 to rotate. During the feeding process, the quick-release feeding turntable 4 will drive the pipe fittings to flow in the S-shaped channel.

[0028] The bidirectional moving mechanism 3 includes a first driving motor 301, a gear 302 and a rack 303. By rotating the first driving motor 301, the gear 302 rotates. Under the rotation of the gear 302, the two racks 303 will approach and move away from each other on the main frame 1 respectively to adjust the distance between the two sliding tables 11. By adjusting the distance between the two sliding tables 11, the processing of pipe fittings with different lengths can be adapted.

[0029] A material rack 10 is detachably connected to each sliding table 11. The cross-section of the material rack 10 is in a U shape. Different material racks 10 are selected and installed on the sliding table 11 according to the diameter of the pipe fitting.

[0030] The disk seat 401 is fixedly connected to the rotating shaft. One end of the positioning and feeding plate 402 is provided with a U-shaped groove for receiving and feeding the pipe fitting. A convex block is provided at the other end of the positioning and feeding plate 402. A slot is opened on the disk seat 401. According to the diameter of the pipe fitting, the positioning and feeding plate 402 with a corresponding size U-shaped groove can be selected and inserted into the slot. The retaining ring 403 is fixedly connected to the disk seat 401. The pin 405 is slidably connected to the disk seat 401. When the positioning and feeding plate 402 is inserted into the slot, it will push the pin 405 until it is inserted into the limiting hole, realizing the locking and limiting of the positioning and feeding plate 402. The pin 405 is fixedly connected to the connecting ring 404. The spring 406 is located between the retaining ring 403 and the connecting ring 404.

[0031] The fixed guide rail 501 is fixedly connected to the sliding table 11. A chute is provided on the sliding table 11. The adjusting guide rail 502 can be adjusted in height along the chute, so as to adjust the gap size of the S-shaped channel and adapt to the feeding and guiding of pipe fittings with different pipe diameters. After the adjusting guide rail 502 is adjusted, it is fixedly connected to the sliding table 11 by screws.

[0032] An inclined groove is provided on the connecting ring 404. An inclined surface is provided at the end of the push fork 601. When it is necessary to replace and install the positioning and feeding plate 402, the disk seat 401 is rotated by the feeding and rotating assembly 2 to make different positioning and feeding plates 402 rotate to the disassembly and assembly station. The push fork 601 is driven to rise for the loosening and clamping action. The piston rod of the loosening and clamping cylinder 6 extends, and after the push fork 601 rises, it will push the connecting ring 404 and the pin 405 out of the limiting hole of the current positioning and feeding plate 402. Then a new positioning and feeding plate 402 is inserted into the loosened slot. After that, the piston rod of the loosening and clamping cylinder 6 retracts, and the connecting ring 404 and the pin 405 are reset and inserted into the limiting hole of the positioning and feeding plate 402 again.

[0033] The pipe rotation assembly 7 includes a first adjusting screw 701, a first slider 702, a second drive motor 703, and a rotating platform 704. The first slider 702 is slidably connected to the sliding platform 11. The lower end of the first adjusting screw 701 is rotatably connected to the first slider 702. The first adjusting screw 701 is threadedly connected to the sliding platform 11. By rotating the first adjusting screw 701, the first adjusting screw 701 is lifted and lowered relative to the sliding platform 11. The first adjusting screw 701 only rotates relative to the first slider 702, and can drive the first slider 702 to slide in the sliding platform 11 to adjust its height. The second drive motor 703 is fixedly connected to the first slider 702, and the rotating platform 704 is fixedly connected to the rotating shaft of the second drive motor 703.

[0034] The pipe tightening assembly 8 includes a second adjusting screw 801, a second slider 802, a tightening cylinder 803 and a tightening platform 804. The second slider 802 is slidably connected to the sliding platform 11, the second adjusting screw 801 is threadedly connected to the sliding platform 11, and the lower end of the second adjusting screw 801 is rotatably connected to the second slider 802. By rotating the second adjusting screw 801, the second adjusting screw 801 is lifted and lowered relative to the sliding platform 11. The second adjusting screw 801 only rotates relative to the second slider 802, which can drive the second slider 82 to slide in the sliding platform 11 to adjust its height. The tightening cylinder 803 is fixedly connected to the second slider 802, and the tightening platform 804 is rotatably connected to the piston rod of the tightening cylinder 803.

[0035] The sliding platform 11 and the fixed guide rail 501 are both provided with clearance holes corresponding to the rotating shaft of the rotating component 2 to avoid interference with the rotation of the rotating shaft.

[0036] The working principle of the present invention is as follows: during use, the distance between the two sliding platforms 11 can be adjusted according to the overall length of the pipe fittings to be welded. When adjusting the distance, the first driving motor 301 drives the gear 302 to rotate. Under the rotation of the gear 302, the two racks 303 will approach and move away from each other on the main machine base 1 respectively to adjust the distance between the two sliding platforms 11; according to the diameter of the pipe fittings to be welded, a suitable material rack 10 is selected and installed on the sliding platform (the cross-section of the material rack 10 is in a U shape, and the size of the notch can adapt to the material feeding and guiding of pipe fittings with different diameters). An elastic plunger can be arranged at the discharging end of the material rack 10 close to the quick-release feeding turntable 4 to ensure that there is elastic resistance when the pipe fittings in the material rack 10 are feeding, so as to ensure that only one pipe fitting falls into the S-shaped channel each time during feeding; then, the gap size of the S-shaped channel is adjusted according to the diameter of the pipe fittings. The height is adjusted by loosening the screws and sliding the adjusting guide rail 502 up and down. After the adjustment of the adjusting guide rail 502 is completed, it is fixedly connected to the sliding platform 11 through screws; the heights of the first slider 702 and the second slider 802 are adjusted according to the diameter of the pipe fittings. By rotating the first adjusting screw 701, the first adjusting screw 701 performs a lifting adjustment action relative to the sliding platform 11. The first adjusting screw 701 only rotates relative to the first slider 702 and can drive the first slider 702 to slide in the sliding platform 11 to adjust its height. The adjustment principle of the second slider 802 is the same as that of the first slider 702; finally, a positioning and dialing plate 402 corresponding to the U-shaped groove with the same diameter as the pipe fittings is selected and installed. When replacing and installing the positioning and dialing plate 402, the feeding rotation assembly 2 drives the disc seat 401 to rotate to make different positioning and dialing plates 402 rotate to the disassembly and assembly station, and the driving fork 601 is driven to rise for the loosening and clamping action. The piston rod of the loosening and clamping cylinder 6 extends, and after the driving fork 601 rises, it will push the connecting ring 404 and the pin 405 out of the limiting hole of the current positioning and dialing plate 402. Then, a new positioning and dialing plate 402 is inserted into the loosened slot. After that, the piston rod of the loosening and clamping cylinder 6 retracts, and the connecting ring 404 and the pin 405 are reset and inserted into the limiting hole of the positioning and dialing plate 402 again.

[0037] During processing, the pipe fitting assemblies to be welded are sequentially fed into the material rack 10 through an external feeding mechanism. Refer to Figure 3Whenever a pipe fitting enters the S-shaped channel, the pipe fitting will fall into a U-shaped groove of a positioning and diverting plate 402, and then the feeding rotating assembly 2 drives it to rotate to the welding station. At this time, the two ends of the pipe fitting are located between the rotating table 704 and the tightening table 804. At this time, the piston rod of the tightening cylinder 803 extends, and the tightening table 804 tightens the pipe fitting on the rotating table 704. Then the second driving motor 703 drives the rotating table 704 to rotate, and the pipe fitting and the tightening table 804 will also rotate together. During this rotation process, the laser welder 9 performs laser welding on the pipe fitting to be welded. After the welding is completed, the pipe fitting flows out of the S-shaped channel during the subsequent rotation of the disc base 401 to complete the processing.
