DETAILED DESCRIPTION

[0023] The following will be combined with the embodiments to clearly and completely describe the technical solution of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0024] Example 1

[0025] like Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 7As shown, a pipeline conveying welding device comprises a base 1, a conveying component 2 and a welding machine 3, wherein the conveying component 2 is located above the base 1, and the welding machine 3 is located above the conveying component 2. A rotating component is provided at one end of the conveying component 2 above the base 1, and the rotating component comprises a supporting seat 7, a rotating mechanism 6, a three-jaw chuck 4 and a spreading component 5. The supporting seat 7 is fixed on the base 1, and the three-jaw chuck 4 is rotatably connected to the supporting seat 7. The spreading component 5 passes through the three-jaw chuck 4 and is slidably connected to the three-jaw chuck 4. The three-jaw chuck 4 is rotated by the rotating mechanism 6. The three-jaw chuck 4 is used to clamp the outer wall of a pipeline, and the spreading component 5 is used to support the inner wall of another pipeline. The three-jaw chuck 4 is provided with a locking screw 401, and the spreading component 5 is fixed to the three-jaw chuck 4 by the locking screw 401, and the spreading component 5 rotates synchronously with the three-jaw chuck 4 by the locking screw 401.

[0026] Through the above technical solution, the first pipeline is moved to the side of the claw of the three-jaw chuck 4 through the conveying component 2, and the outer wall of the pipeline is clamped and fixed by the three-jaw chuck 4. Then the second pipeline is moved to one end close to the first pipeline through the conveying component 2. At this time, the expansion component 5 extends into the second pipeline, and the expansion component 5 is pressed against the second pipeline, and then the expansion component 5 is fixed to the three-jaw chuck 4 by the locking screw 401, so that the second pipeline and the expansion component 5 are fixed to the three-jaw chuck 4 as a whole. At this time, the welding machine 3 is located above the joint of the two pipelines. Then the rotating component is started to drive the three-jaw chuck 4 to rotate, and the upper welding machine 3 is started. At this time, the first pipeline and the second pipeline complete synchronous rotation under the action of the three-jaw chuck 4 and the expansion component 5 until the circumferential welding of the two pipelines is completed. The above structure can ensure that the two pipelines keep rotating synchronously during welding, and improve the welding accuracy.

[0027] Furthermore, the expansion assembly 5 includes an outer tube 501, an inner tube 502, a slide cylinder 503, a mounting plate 506 and a connecting rod assembly 504, the inner tube 502 extends into the outer tube 501, the outer tube 501 passes through the middle part of the three-jaw chuck 4, the mounting plate 506 is fixed to one end of the outer tube 501 close to the claws of the three-jaw chuck 4, the slide cylinder 503 is sleeved on the outer tube 501, three connecting rod assemblies 504 are circumferentially arrayed on the outside of the outer tube 501, one end of the connecting rod assembly 504 passes through the mounting plate 506, and the other end of the connecting rod assembly 504 is hinged to the slide cylinder 503, and an abutment block 505 is provided at one end of the connecting rod assembly 504 away from the mounting plate 506, and the abutment block 505 moves along the radial direction of the mounting plate 506 through the connecting rod assembly 504 and the slide cylinder 503.

[0028] Furthermore, a clamp 508 is provided on the side of the outer tube 501 away from the clamping claws of the three-jaw chuck 4, one end of the clamp 508 is connected to the outer tube 501, and the other end of the clamp 508 is connected to the inner tube 502, and the inner tube 502 slides in the outer tube 501 through the clamp 508, and a stopper 507 is provided at one end of the inner tube 502 close to the slide cylinder 503, and the stopper 507 extends out of the outer tube 501, and a sliding groove is provided on the outer tube 501 corresponding to the position of the stopper 507, and the stopper 507 slides along the sliding groove, and the stopper 507 abuts against the end of the slide cylinder 503.

[0029] Through the above technical solution, when the opening assembly 5 is not working, the slide 503 is away from the mounting plate 506, the connecting rod assembly 504 is in a retracted state, and the abutment block 505 is retracted and located in the mounting plate 506. When the opening assembly 5 is in operation, the distance of the outer tube 501 in the three-jaw chuck 4 can be moved according to the length of the pipeline, so as to adjust the specific position of the opening. After adjusting the position of the outer tube 501, the clamp 508 is pulled, and the inner tube 502 slides in the direction of the mounting plate 506. Since the stopper 507 at the end of the inner tube 502 is slidably connected with the outer tube 501 through the slide groove, the stopper 507 pushes the slide 503 to move in the direction of the mounting plate 506, and the connecting rod assembly 504 is opened, and at the same time, the connected abutment block 505 is stretched, so that the abutment block 505 extends out of the mounting plate 506 and abuts against the inner wall of the pipeline to complete the abutment.

[0030] It can be known that the inner dimension of the pipe that the expansion assembly 5 can expand is larger than the dimension of the mounting plate 506, so that the expansion assembly 5 can be inserted into the pipe; at the same time, the inner dimension of the pipe is not larger than the dimension that can be fully expanded by the abutment block 505. At the same time, by pulling the clamp 508, the inner pipe 502 and the outer pipe 501 can be kept relatively fixed, so that the expansion assembly 5 is prevented from loosening when supporting the pipe, and is convenient for subsequent synchronous rotation with the three-jaw chuck 4.

[0031] Furthermore, the outer sleeve of the three-jaw chuck 4 is provided with a bearing, and the three-jaw chuck 4 is rotatably connected to the support seat 7 through the bearing. The rotating mechanism 6 includes an outer ring gear 601 and a driving motor 602. The outer ring gear 601 is sleeved on the three-jaw chuck 4, and the driving motor 602 is located on one side of the three-jaw chuck 4 and fixed on the base 1. The driving motor 602 is provided with a driving gear, and the driving gear is meshed with the outer ring gear 601. The outer ring gear 601 is rotated by the driving motor 602.

[0032] Through the above technical solution, an outer gear ring 601 is arranged outside the three-jaw chuck 4, and the outer gear ring 601 is driven to rotate by the driving gear of the driving motor 602, thereby driving the three-jaw chuck 4 to rotate. At the same time, the three-jaw chuck 4 is supported by the bearing and the support seat 7 to improve the stability of rotation.

[0033] Furthermore, a plurality of the conveying components 2 are arranged in an array on one side of the jaws of the three-jaw chuck 4, and the conveying components 2 include a V-shaped groove 201, a connecting plate 202, a support plate 203 and a support column 205 from top to bottom, the V-shaped groove 201 is fixed to the connecting plate 202, an adjusting screw is provided between the connecting plate 202 and the support plate 203, the support plate 203 is fixed on the support column 205, one end of the adjusting screw is fixed to the connecting plate 202, one end of the nut of the adjusting screw passes through the support plate 203 and is connected to the support plate 203 by a nut, and a roller is provided in the V-shaped groove 201.

[0034] Through the above technical solution, the pipeline can be easily transported through the rollers in the V-groove 201. At the same time, the height of the V-groove 201 and the connecting plate 202 can be adjusted by adjusting the bolts 204 to adapt to pipelines of different diameters, making it convenient for the pipeline to be clamped by the three-jaw chuck 4 for subsequent welding.

[0035] Furthermore, the locking screw 401 is located on a side of the three-jaw chuck 4 away from the jaws, and an end of the locking screw 401 abuts against the outer tube 501 .

[0036] Through the above technical solution, by tightening the locking screw 401, the locking screw 401 is pressed against the outer tube 501, and the outer tube 501 and the three-jaw chuck 4 are connected as a whole through the action of friction, and the outer tube 501 is connected to the inner tube 502 through the clamp 508, so the expansion component 5 can rotate synchronously with the three-jaw chuck 4.

[0037] like Figure 2 and Figure 3 As shown, two pipes with the same diameter are clamped by a three-jaw chuck 4, and the other is tightened by a spreading assembly 5. The two pipes are rotated synchronously by the rotating assembly to improve the welding accuracy.

[0038] Example 2

[0039] Based on Example 1, refer to Figure 4 , Figure 5As shown, a pipe is clamped and fixed by a three-jaw chuck 4, and the bottom of the pipe is supported by a conveying assembly 2. At this time, a reducer is close to the pipe, and the small end of the reducer is supported by a propping assembly 5, and the lower part of the reducer is supported by a raised conveying assembly 2. Then the three-jaw chuck 4 is driven to rotate by a rotating mechanism 6, so that the pipe and the reducer rotate synchronously, and then the welding is completed. The three-jaw chuck 4 and the propping assembly 5 can complete the welding of the pipe and the reducer, thereby improving the utilization rate of the equipment and the use effect.
