[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figures 1-6 As shown, the technical solution adopted by this utility model is as follows: a steel structure welded pipe processing and positioning device. It includes a processing table 1. Two first sliding grooves 2 are formed on the processing table 1. A support frame 5 is fixedly installed on the processing table 1 between the two first sliding grooves 2. A processing device 6 is installed on the support frame 5.

[0028] A support plate 7 is slidably installed on each of the first slide grooves 2.

[0029] Specifically, a lead screw 3 with its axis arranged horizontally is rotatably mounted on the processing table 1, and the lead screw 3 is connected to the support plate 7 by threads. The threads connecting the two support plates 7 to the lead screw 3 have opposite directions of rotation.

[0030] Furthermore, a first motor 4 is fixedly installed on the processing table 1, and the output shaft of the first motor 4 is connected to the lead screw 3 via a reducer.

[0031] Start the first motor 4. The first motor 4 rotates, which can drive the lead screw 3 to rotate. When the lead screw 3 rotates, it can drive the two support plates 7 to move towards or away from each other.

[0032] Each of the aforementioned support plates 7 has a first rotating ring 8 rotatably installed inside it.

[0033] Specifically, a second motor 15 is fixedly mounted on the support plate 7. The output shaft of the second motor 15 is parallel to the axis of the first rotating ring 8. A gear 16 is fixedly mounted on the output shaft of the second motor 15. A gear ring 11 that meshes with the gear 16 is fixedly mounted on the outer end face of the first rotating ring 8.

[0034] Start the second motor 15. The second motor 15 drives the first rotating ring 8 to rotate through the meshing of the first rotating ring 8 and the gear 16.

[0035] A second rotating ring 9, parallel to the first rotating ring 8, is rotatably mounted inside the support plate 7. A fixing module for fixing the position of the second rotating ring 9 is installed between the support plate 7 and the second rotating ring 9.

[0036] Specifically, the fixing module includes: a spring positioning pin 18 and a slot 17.

[0037] The support plate 7 has a guide blind hole arranged radially along the support plate 7. The spring positioning pin 18 is slidably connected to the guide blind hole. A second spring is installed between the spring positioning pin 18 and the guide blind hole. One end of the second spring is fixed to the spring positioning pin 18, and the other end of the second spring is fixed to the guide blind hole.

[0038] The slot 17 is formed on the outer circumference of the second rotating ring 9. The spring positioning pin 18 is positioned near the slot 17 with an arc surface, and the slot 17 and the spring positioning pin 18 cooperate with each other.

[0039] When the spring positioning pin 18 is located in the slot 17, the position of the second rotating ring 9 is fixed.

[0040] The axes of the first rotating ring 8 and the second rotating ring 9 are both horizontally arranged in the left-right direction, and each of the first rotating ring 8 and the second rotating ring 9 has a mounting hole at its center. Two clamping plates 10 are slidably installed in the mounting holes, and the clamping plates 10 can move radially along the first rotating ring 8. Preferably, the clamping plates 10 are configured as arc-shaped blocks, and friction strips are installed on the arc-shaped blocks.

[0041] A drive module for driving the clamping plate 10 to slide is installed between the first rotating ring 8 and the clamping plate 10.

[0042] Furthermore, the drive module includes: a limiting slide 12, a slide rod 13, a second slide 19, and a first spring 21.

[0043] The limiting slide groove 12 is provided in two parts and corresponds one-to-one with the clamping plate 10. The limiting slide groove 12 is arc-shaped and the distance between the two ends of the limiting slide groove 12 and the axis of the first rotating ring 8 is different.

[0044] Assuming that initially the slide bar 13 is located at one end of the limiting slide groove 12 as the initial end, and after the first rotating ring 8 drives the limiting slide groove 12 to rotate, the first rotating ring 8 is located at one end of the limiting slide groove 12 as the final end, then the distance between the initial end and the axis of the first rotating ring 8 should be greater than the distance between the final end and the axis of the first rotating ring 8.

[0045] Two slide rods 13 are provided and correspond one-to-one with the clamping plates 10. The slide rods 13 are located in the limiting slide grooves 12, and a slider 20 is fixedly installed on each clamping plate 10.

[0046] Two second sliding grooves 19 are provided, each corresponding to one of the clamping plates 10. Each second sliding groove 19 is formed on the second rotating ring 9 and extends radially along the second rotating ring 9. A fixed post 22, arranged radially along the second rotating ring 9, is fixedly installed within each second sliding groove 19. The slider 20 is slidably connected to the fixed post 22.

[0047] The first spring 21 is sleeved on the fixed post 22. One end of the first spring 21 is fixed to the slider 20, and the other end of the first spring 21 is fixed to the fixed post 22.

[0048] When the first rotating ring 8 rotates, it drives the limiting slide groove 12 to rotate together. Since the clamping plate 10 is installed on the second rotating ring 9, and the second rotating ring 9 is limited by the fixing module, the limiting slide groove 12 will push the slide rod 13 and the slider 20 to slide along the fixing post 22, thereby causing the clamping plate 10 to move inward along the radial direction of the second rotating ring 9, the first spring 21 is compressed and deformed, and the clamping plate 10 clamps the workpiece to be processed.

[0049] When the first rotating ring 8 rotates in the opposite direction, it drives the limiting slide groove 12 to rotate together. Since the clamping plate 10 is installed on the second rotating ring 9, and the second rotating ring 9 is limited by the fixing module, the first spring 21 will push the slide rod 13 and the slider 20 to slide along the fixing post 22, thereby causing the clamping plate 10 to move outward along the radial direction of the second rotating ring 9, and the clamping plate 10 to release the workpiece to be processed.

[0050] The specific usage method of this application is as follows:

[0051] First, the pipe to be welded is placed between the clamps 10 at both ends. Then, the second motor 15 is started. This causes the gear 16 to rotate, which in turn drives the gear ring 11 to rotate, and the gear ring 11 drives the first rotating ring 8 to rotate. Since the spring positioning pin 18 is located in the slot 17 at this time, the rotation of the first rotating ring 8 does not drive the second rotating ring 9 to rotate synchronously.

[0052] As the first rotating ring 8 rotates, the diameter of the contact point between the limiting groove 12 and the slide rod 13 decreases. This causes the slide rod 13 to drive the slider 20 to slide within the second groove 19. Consequently, the clamping plate 10 moves closer to the welded pipe, thus clamping the welded pipe.

[0053] Then, the second motor 15 stops and the first motor 4 starts. The lead screw 3 rotates, which drives the two end support plates 7 to move closer together, thereby adjusting the position of the pipe to be welded.

[0054] After completing the above steps, the welded pipe can be processed using processing device 6.

[0055] During the processing, the second motor 15 can be restarted, which will continue to drive the gear 16 to rotate, thereby causing the gear ring 11 and the first rotating ring 8 to continue rotating. Since the clamping plate 10 has already clamped the welded pipe, the slide rod 13 will not move. This will cause the slide rod 13 to rotate with the rotation of the first rotating ring 8, thereby causing the slider 20 and the second rotating ring 9 to rotate as a whole with the rotation of the first rotating ring 8.

[0056] As the second rotating ring 9 rotates together with the first rotating ring 8, the spring positioning pin 18 disengages from the slot 17. The rotation of the second rotating ring 9 together with the first rotating ring 8 will cause the welded pipe to rotate, which facilitates the processing of the entire outer surface of the welded pipe until the processing is completed after the welded pipe has rotated one revolution.

[0057] When the welded pipe completes one revolution of processing, the spring positioning pin 18 automatically engages with the slot 17 again under the action of the second spring. Starting the second motor 15 causes it to reverse, simultaneously driving the first rotating ring 8 to rotate in the opposite direction. The first rotating ring 8 drives the limiting slide groove 12 to rotate together. Since the clamping plate 10 is mounted on the second rotating ring 9, and the second rotating ring 9 is limited by the fixing module, the first spring 21 pushes the slide rod 13 and the slider 20 to slide along the fixing post 22, thereby causing the clamping plate 10 to move radially outward along the second rotating ring 9, releasing the processed welded pipe.

[0058] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
