Description

Technical Field

[0001] The invention relates to the technical field of pipeline processing, and in particular to a splicing welding device for industrial pipeline processing. Background Art

[0002] When industrial pipelines are connected vertically, they need to be processed into a tee-like structure for splicing. The tee serves as the main body of the industrial pipeline. First, a notch is cut on one side of a pipe to serve as the main pipe, and then a plug is cut out at one end of the other pipe to serve as a branch pipe. One end of the branch pipe matches the notch of the main pipe, and then the joints of the two pipes are welded.

[0056] A main pipe positioning mechanism is installed on the top of the turntable 2 and is provided with multiple ones for positioning the main pipe 4 to be welded. The main pipe positioning mechanism includes a first fixed seat 6 fixedly connected to the top of the turntable 2, a rotating plate 7 rotatably connected to the outer wall of one side of the first fixed seat 6, a supporting plate 8 fixedly connected to the bottom of one side of the rotating plate 7, and a positioning cylinder 9 arranged on the top of the supporting plate 8; a plurality of inner support assemblies are arranged inside the positioning cylinder 9; the inner support assembly includes a fixed plate 10 fixedly connected to the inside of the positioning cylinder 9 and a plurality of hydraulic cylinders 11 installed on the top of the fixed plate 10, the extended end of the hydraulic cylinder 11 is fixedly connected to a driven block 12, the outside of the driven block 12 is slidably connected to an inner support block 13 of an arc structure, the outer walls on both sides of the driven block 12 are fixedly connected to first springs 14, and the other end of the first spring 14 is fixedly connected to the inner wall of the inner support block 13;

[0057] The staff places the main pipe 4 with one side of the cutout on the outer wall facing the first support seat 15 outside the positioning cylinder 9, controls the extension of each hydraulic cylinder 11, and drives the inner support block 13 to abut against the inner wall of the main pipe 4 through the driven block 12 to center the main pipe 4.

[0058] The branch pipe positioning mechanism is installed on the top of the turntable 2 and is provided with multiple ones. The branch pipe positioning mechanism is arranged on one side of the main positioning mechanism and is used to position the branch pipe 5 to be welded. The branch pipe positioning mechanism includes a first support seat 15 fixedly connected to the top of the turntable 2, a second support seat 16 arranged on one side of the first support seat 15, and an auxiliary adjustment component installed inside the first support seat 15; the tops of the first support seat 15 and the second support seat 16 are both provided with positioning grooves 17, and an electromagnet 18 is installed inside one of the positioning grooves 17; the top of the turntable 2 is provided with a first slide groove 19, and the first slide groove 19 is slidably connected with a first slider 20, and the first slider 2 0 is fixedly connected to the bottom of the second support seat 16; a second spring 21 is also fixedly connected to the outer wall of one side of the first slider 20, and the other end of the second spring 21 is fixedly connected to the inner wall of the first slide groove 19. Two auxiliary adjustment components are provided, and the auxiliary adjustment components include a second slide groove 22 opened inside the first support seat 15, a positioning block 23 slidably connected inside the second slide groove 22, and a plurality of third springs 24 fixedly connected to the bottom of the positioning block 23; the top of the positioning block 23 extends to the inside of another positioning groove 17, and the top of the positioning block 23 is provided with an inclined groove, which cooperates with the branch pipe 5; the bottom end of the third spring 24 is fixedly connected to the inner wall of the bottom of the second slide groove 22;

[0059] The staff puts the end of the branch pipe 5 that matches the cutout of the main pipe 4 toward the positioning cylinder 9 and places it inside the positioning groove 17 at the top of the first support seat 15 and the second support seat 16. The positioning block 23 limits the bottom of the branch pipe 5 and positions one end of the main pipe 4. The electromagnet 18 is energized and the electromagnet 18 acts on the branch pipe 5 to fix the branch pipe 5 and the second support seat 16 together. Then, the branch pipe 5 and the second support seat 16 can move synchronously. When the branch pipe 5 moves, the positioning block 23 is driven to move downward, and the third spring 24 is compressed. After the branch pipe 5 and the main pipe 4 are welded together and taken out, the positioning block 23 is driven to move upward and reset by the rebound force of the third spring 24.

[0060] When the second support seat 16 moves toward the first support seat 15, the first slider 20 is driven to slide synchronously along the inner wall of the first slide groove 19, and the second spring 21 is compressed accordingly. After the branch pipe 5 and the main pipe 4 are welded together and taken out, the second support seat 16 is driven to reset by the rebound force of the second spring 21;

[0061] Furthermore, after the branch pipe 5 and the main pipe 4 are butt-joined together, the fixation of the branch pipe 5 is released by de-energizing the electromagnet 18 , thereby not affecting the subsequent rotation of the branch pipe 5 and the main pipe 4 .

[0062] The automatic docking mechanism is installed on the turntable 2 and cooperates with the branch pipe positioning mechanism to drive the branch pipe 5 to move and dock with the main pipe 4. The automatic docking mechanism includes a third slide groove 25 opened inside the turntable 2, a second slider 26 slidably connected inside the third slide groove 25, a driving roller 27 rotatably connected inside the second slider 26, and a displacement component for driving the second slider 26 to move; the end of the driving roller 27 close to the second support seat 16 is a conical structure; the interior of the driving roller 27 is slidably connected with a first transmission shaft 28, and the first transmission shaft The outer part of the first transmission shaft 28 is rotatably sleeved with a second fixed seat, and the second fixed seat is fixedly connected to the top of the turntable 2. The outer part of the first transmission shaft 28 is equipped with a first one-way gear 29. The displacement assembly includes a second transmission shaft 30 rotatably connected to the bottom of the turntable 2, a reciprocating screw 31 fixedly sleeved on the outer part of the second transmission shaft 30, and a first gear 32 fixedly connected to one end of the second transmission shaft 30; the second slider 26 is screwed on the outer part of the reciprocating screw 31; the inner part of the base 1 is fixedly connected with a first gear ring 33, and the first gear 32 is meshed with the first gear ring 33;

[0063] After the main pipe 4 and the branch pipe 5 are placed, the turntable 2 is driven by the driving mechanism to rotate a quarter of a turn clockwise and then stop. In this process, the second transmission shaft 30 is driven to rotate through the meshing effect between the first gear 32 and the first gear ring 33, and the reciprocating screw 31 rotates synchronously therewith, thereby driving the second slider 26 to move from one end of the reciprocating screw 31 to the other end thereof, that is, to move toward the main pipe 4. In this process, the driving roller 27 is driven to abut against the branch pipe 5, and a part of the tapered end of the driving roller 27 is inserted into the branch pipe 5, and the branch pipe 5 is driven to move synchronously, so that the branch pipe 5 and the main pipe 4 are docked together;

[0064] After the branch pipe 5 and the main pipe 4 are butt-jointed and welded, the drive mechanism continues to drive the turntable 2 to rotate a quarter of a turn and then stops. During this process, the meshing action between the first gear 32 and the first gear ring 33 drives the second transmission shaft 30 and the reciprocating screw 31 to continue to rotate, thereby driving the second slider 26 to move back and reset, and then driving the driving roller 27 to reset, so that the staff can take out the welded main pipe 4 and branch pipe 5 upwards.

[0065] The active adjustment mechanism is connected to the main pipe positioning mechanism and is used to drive the main pipe 4 to rotate back and forth when the branch pipe 5 moves. The active adjustment mechanism includes a slide plate 34 slidably connected to the inside of the support plate 8, a turntable 35 rotatably connected to the inside of the slide plate 34, and a third transmission shaft 36 fixed to the bottom of the turntable 35; a plurality of fourth springs 37 are fixedly connected to the outer wall of one side of the slide plate 34, and the other end of the fourth spring 37 is fixedly connected to the inner wall of the support plate 8; two racks 38 are fixedly connected to the inner wall of the bottom of the support plate 8, and the tooth grooves in the two racks 38 are arranged oppositely; a second gear 39 is fixedly sleeved on the outside of the third transmission shaft 36, and the second gear 39 is located between the two racks 38, and the second gear 39 is meshed with the two racks 38 in sequence when moving; a limit block 49 is installed on the top of one side of the support plate 8;

[0066] When the branch pipe 5 moves and contacts the main pipe 4, it drives the main pipe 4 to move, and then drives the slide plate 34 to move synchronously through the positioning cylinder 9 and the rotating disk 35. The fourth spring 37 is compressed, and at the same time drives the third transmission shaft 36 and the second gear 39 outside it to move synchronously. In this process, the second gear 39 first meshes with one of the racks 38, driving the third transmission shaft 36 to rotate 30° in one direction. After the second gear 39 loses meshing with the current rack 38, it immediately meshes with another rack 38 and drives the third transmission shaft 36 to rotate 60°. During this process, the main pipe 4 can be driven to rotate 30° in different directions through the turntable 35, the positioning cylinder 9 and the inner support assembly. During this process, one end of the branch pipe 5 will be inserted into the cutout of the main pipe 4 and docked with the main pipe 4. If it is docked with the main pipe 4 in advance, as the turntable 35 and the positioning cylinder 9 rotate, the driven block 12 is driven to slide along the inner wall of the inner support block 13. At this time, the main pipe 4 and the branch pipe 5 stop rotating after docking, thereby realizing automatic docking of the main pipe 4 and the branch pipe 5 without manual calibration and docking.

[0067] The auxiliary welding mechanism is installed inside the base 1 and is used to drive the branch pipe 5 and the main pipe 4 connected together to rotate. The auxiliary welding mechanism includes a first driving shaft 40 rotatably connected to the inner wall of the bottom of the base 1, a toothed disc 41 fixedly connected to the top of the first driving shaft 40, and a motor 42 installed on the inner wall of the bottom of the base 1; the third gear 43 is fixedly sleeved on the outside of the output shaft of the motor 42, and a second one-way gear 44 is installed on the outside of the first driving shaft 40, and the third gear 43 is meshed with the second one-way gear 44; the toothed disc 41 is meshed with the first one-way gear 29;

[0068] When the turntable 2 rotates clockwise, the driving roller 27, the first transmission shaft 28 and the first one-way gear 29 are driven to perform an orbital motion around the first driving shaft 40. In this process, since the first one-way gear 29 is meshed with the toothed disc 41, the first one-way gear 29 will rotate accordingly, but the first transmission shaft 28 will not rotate accordingly.

[0069] When it is necessary to weld the main pipe 4 and branch pipe 5 that are connected together, the third gear 43 is driven to reverse by controlling the motor 42, and the first drive shaft 40 is driven to rotate forward through the meshing effect between the third gear 43 and the second one-way gear 44. At this time, the third one-way gear 47 also rotates accordingly, but the second drive shaft 45 does not rotate accordingly. When the first drive shaft 40 rotates forward, the gear plate 41 is driven to rotate forward synchronously, and the first transmission shaft 28 is driven to rotate through the meshing effect between the gear plate 41 and the first one-way gear 29, thereby driving the drive roller 27 to rotate, thereby driving the branch pipe 5 and the main pipe 4 to rotate synchronously, so as to cooperate with the laser welding machine 3 to weld the connection between the branch pipe 5 and the main pipe 4 in sequence.

[0070] The driving mechanism is installed inside the base 1 and is used to drive the turntable 2 to rotate in sections. The driving mechanism includes a second driving shaft 45 rotatably connected to the inner wall of the bottom of the base 1 and a second gear ring 46 fixed to the bottom of the turntable 2; a third one-way gear 47 is installed outside the second driving shaft 45, and the third one-way gear 47 is meshed with the third gear 43; a fourth gear 48 is also fixedly sleeved outside the second driving shaft 45, and the fourth gear 48 is meshed with the second gear ring 46;

[0071] The third gear 43 is driven to rotate forward by controlling the motor 42, and the second drive shaft 45 is driven to rotate reversely through the meshing effect between the third gear 43 and the third one-way gear 47. At this time, the second one-way gear 44 also rotates accordingly, but the first drive shaft 40 does not rotate accordingly. When the second drive shaft 45 rotates, it drives the fourth gear 48 to rotate synchronously, and the meshing effect of the fourth gear 48 and the second gear ring 46 drives the turntable 2 to rotate forward, and drives the turntable 2 to pause every quarter turn.

[0072] Working principle: When in use, the staff will place one side of the cutout on the outer wall of the main pipe 4 toward the first support seat 15 and place it outside the positioning cylinder 9. By controlling the extension of each hydraulic cylinder 11, the inner support block 13 is driven by the driven block 12 to abut against the inner wall of the main pipe 4 to center the main pipe 4. At the same time, the end of the branch pipe 5 that matches the cutout of the main pipe 4 is placed toward the positioning cylinder 9 and placed inside the positioning groove 17 at the top of the first support seat 15 and the second support seat 16. The positioning block 23 limits the bottom of the branch pipe 5 to position one end of the main pipe 4, and the electromagnet 18 is energized to fix the branch pipe 5 and the second support seat 16 together through the suction effect of the electromagnet 18. After the main pipe 4 and the branch pipe 5 are placed, the driving mechanism drives The turntable 2 stops after rotating a quarter of a turn clockwise. During this process, the second transmission shaft 30 is driven to rotate through the meshing effect between the first gear 32 and the first gear ring 33, and the reciprocating screw 31 rotates synchronously therewith, thereby driving the second slider 26 to move from one end of the reciprocating screw 31 to the other end thereof, that is, to move toward the main pipe 4. During this process, the driving roller 27 is driven to abut against the branch pipe 5, and a part of the tapered end of the driving roller 27 is inserted into the branch pipe 5, and drives the branch pipe 5 to move synchronously. When the branch pipe 5 moves and abuts against the main pipe 4, it drives the main pipe 4 to move, and then drives the slide plate 34 to move synchronously through the positioning cylinder 9 and the turntable 35, and the fourth spring 37 is compressed, and at the same time drives the third transmission shaft 36 and the second gear 39 outside thereof to move synchronously. The second gear 39 first meshes with one of the racks 38, driving the third transmission shaft 36 to rotate 30° in one direction. After the second gear 39 loses meshing with the current rack 38, it meshes with another rack 38 and drives the third transmission shaft 36 to rotate 60°. Therefore, in this process, the main pipe 4 can be driven to rotate 30° in different directions respectively through the turntable 35, the positioning cylinder 9 and the inner support assembly. In this process, one end of the branch pipe 5 will be inserted into the cutout of the main pipe 4 and docked with the main pipe 4. If it is docked with the main pipe 4 in advance, as the turntable 35 and the positioning cylinder 9 rotate, the driven block 12 is driven to slide along the inner wall of the inner support block 13. At this time, the main pipe 4 and the branch pipe 5 stop rotating after docking. , thereby realizing the automatic docking of the main pipe 4 and the branch pipe 5, without manual calibration docking. After the main pipe 4 and the branch pipe 5 are docked together, the third gear 43 is driven to reverse by controlling the motor 42, and the first drive shaft 40 is driven to rotate forward through the meshing effect between the third gear 43 and the second one-way gear 44, thereby driving the gear plate 41 to rotate forward synchronously, and the first transmission shaft 28 is driven to rotate through the meshing effect between the gear plate 41 and the first one-way gear 29, thereby driving the driving roller 27 to rotate, thereby driving the branch pipe 5 and the main pipe 4 to rotate synchronously, so as to cooperate with the laser welding machine 3 to perform welding processing on the connection between the branch pipe 5 and the main pipe 4 in sequence. After the welding is completed, the turntable 2 is driven by the driving mechanism to continue to rotate a quarter of a turn and then stop. In this process,The meshing action between the first gear 32 and the first gear ring 33 drives the second transmission shaft 30 and the reciprocating screw 31 to continue to rotate, thereby driving the second slider 26 to move back and reset, and then driving the driving roller 27 to reset, and controlling the hydraulic cylinders 11 to contract, release the fixation of the main pipe 4, so that the staff can take out the welded main pipe 4 and branch pipe 5 upwards.
