Description

Technical Field

[0001] The utility model relates to the technical field of welding equipment, in particular to a round pipe welding device which is easy to adjust. Background Art

[0002] Welding, also known as fusion, is a manufacturing process and technology that joins metals or other thermoplastic materials by heating, high temperature or high pressure. There are many sources of energy for modern welding, including gas flame, arc, laser, electron beam, friction and ultrasonic.

[0003] When welding different workpieces, in addition to the different welding forms, different devices are often used for welding when welding workpieces of different shapes.

[0004] In the existing welding seam processing, it is often necessary to weld a circular tubular workpiece, including butt welding of two circular tubular workpieces. When welding such workpieces, the weld is basically annular, and the welding gun needs to be placed around the tubular workpiece for welding, or the tubular workpiece needs to be rotated during the welding process, so that the welding gun can weld the weld of the tubular workpiece.

[0005] In the prior art, such welds are mostly welded by hand or by a robot arm or by some special equipment. The quality of manual welding cannot be guaranteed, it is more dependent on the operator's skills, and the efficiency is low. Although robot arm welding has a high degree of automation, it is expensive. Although the cost of special equipment is lower than that of a robot arm, it is generally used for welding a certain type of tubular workpiece. When replacing other models or other types of tubular workpieces, many accessories need to be replaced, which is troublesome to use. Utility Model Content

DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0022] Figures 1 to 4 Shown is an embodiment of the utility model.

[0023] Embodiment 1:

[0024] like Figure 1 , 2 As shown, a round tube welding device that is easy to adjust includes a processing table 1, a welding module 2 is arranged on one side of the processing table 1, two rotating tubes 3 are arranged at intervals on the upper side of the processing table 1, and a clamping plate 4 is adjustable in the two rotating tubes 3, and a driving motor for driving the rotating tube 3 to rotate is arranged on the processing table 1; a mounting frame 5 is arranged on one side of the processing table 1, and a lifting frame 6 is arranged on the mounting frame 5 at a position aligned between the two rotating tubes 3, and the welding module 2 is slidably installed on the lifting frame 6 through a lifting block 7. When welding, two tubular workpieces that need to be butt-welded are placed in the two rotating tubes 3 respectively, and fixed by the clamping plate 4 after the welds are aligned, and the welding module 2 is driven by the lifting block 7 to align with the weld, and then the rotating tube 3 is driven by the driving motor to rotate during the welding process, so that the weld can be uniformly welded. According to tubular workpieces of different models and sizes, it can be adjusted by adjusting the clamping plate 4, so that tubular workpieces of various sizes can be used. By setting the lifting frame 6 and the lifting block 7, the distance between the welding module 2 and the weld can be adjusted, so that it can be adjusted when performing different welding.

[0025] Two support blocks 8 are arranged on the processing table 1, and a rotating hole 9 is arranged on each of the two support blocks 8. The two rotating holes 9 are arranged in alignment, and the middle parts of the two rotating tubes 3 are respectively arranged to rotate in the two rotating holes 9. By arranging the support blocks 8, it is possible to provide a good supporting force for the rotating tube 3, and with the help of the rotating holes 9, the rotating tube 3 can rotate smoothly when the tubular workpiece is welded. A limiting ring groove is arranged in a depression around the outer wall of the rotating tube 3, and a limiting ring or a limiting block matching the limiting ring groove is convexly arranged on the hole wall of the rotating hole 9. When the rotating tube 3 rotates, the limiting ring or the limiting block slides in the limiting ring groove. In this way, it can ensure that the rotating tube 3 rotates smoothly in the rotating hole 9, and it can also ensure that the rotating tube 3 does not move along the length direction of the rotating hole 9 when rotating.

[0026] A driven pulley 10 is sleeved on the outer wall surrounding one of the rotating tubes 3, and a driving pulley is sleeved on the output shaft of the driving motor, and the driving pulley is connected to the driven pulley 10 through a transmission belt 11. The driving motor can be a servo motor, which can accurately control the rotation speed and rotation angle, and can make the weld more uniform during welding. The speed can be adjusted by the diameter ratio between the driven pulley 10 and the driving pulley through the belt transmission.

[0027] like Figure 2 As shown, the first threaded holes 12 that penetrate the inside and outside are provided on the opposite sides of the rotating tube 3, and the first threaded rods 13 are matched with the inner threads of the two first threaded holes 12. One end of the two first threaded rods 13 is connected to the clamping plate 4 inside the rotating tube 3, and the other end is connected to the first knob plate 14 outside the rotating tube 3. Graduation lines are provided along the length of the first threaded rods 13. When welding is required, the two clamping plates 4 are placed in the upper and lower positions. The position of the clamping plate 4 placed below is adjusted according to the diameter of the workpiece to be processed. The first threaded rod 13 is driven to the clamping plate 4 to be placed in a suitable position by rotating the first knob plate 14. For example, to fix the workpiece in the center position of the rotating tube 3, the two first threaded rods 13 need to be screwed in 50 mm respectively, so the first threaded rod 13 placed at the bottom is screwed in 50 mm first. After the screwing is completed, the workpiece is fitted with the adjusted clamping plate 4, and the other clamping plate 4 is adjusted to cooperate with the clamping workpiece. Under normal circumstances, two first threaded rods 13, first threaded holes 12, clamping plates 4 and other components are provided near the two ends of the rotating tube 3. In this way, when welding workpieces with longer lengths, two positions of a single workpiece can be fixed and supported, which can improve the stability of support and fixation.

[0028] The clamping plate 4 is provided with a through hole 15 that passes through both sides, and one end of the first threaded rod 13 passes through the through hole 15 and is connected to a limiting plate 16; the clamping plate 4 is provided with a receiving groove 17 that surrounds the through hole 15 and is used to receive the limiting plate 16. By providing the through hole 15, when the first threaded rod 13 rotates, the clamping plate 4 is held or the clamping plate 4 is pressed against the workpiece, and the clamping plate 4 does not rotate with the first threaded rod 13, so that the clamping plate 4 is pressed against the workpiece. With the help of the receiving groove 17, the limiting plate 16 can be prevented from protruding from the surface of the clamping plate 4.

[0029] Embodiment 2:

[0030] Based on the above embodiments, Figure 3 , 4 As shown, the lifting frame 6 is provided with a concave slide rail groove 18, and the lifting block 7 is provided with a slide rail block 19 matching the slide rail groove 18; the lifting block 7 is provided with a second threaded hole 20 aligned with the slide rail groove 18, and the second threaded rod 21 is connected to the second threaded hole 20 with a matching inner thread, one end of the second threaded rod 21 is placed in the slide rail groove 18, and the other end is connected to the second knob plate 22. Through the slide rail groove 18 and the slide rail block 19, the lifting block 7 can slide smoothly on the lifting frame 6. The cross-sections of the slide rail groove 18 and the slide rail block 19 are "T" shaped or similar shapes, which can prevent the slide rail block 19 from easily falling off from the slide rail groove 18. When the lifting block 7 is moved to a suitable position, the second threaded rod 21 is connected to the bottom of the slide rail groove 18 by rotating the second knob plate 22, thereby fixing the position of the lifting block 7.

[0031] The clamping plate 4 is arc-shaped, and a rubber layer is provided on one side of the clamping plate 4 for fitting the workpiece. By providing the arc-shaped clamping plate 4, the surface of the tubular workpiece can be more closely fitted. By providing the rubber layer, the surface of the workpiece can be protected.

[0032] Although the utility model is described herein with reference to a plurality of illustrative embodiments of the utility model, it should be understood that those skilled in the art may devise many other modifications and implementations that fall within the scope and spirit of the principles disclosed herein. More specifically, within the scope of the disclosure, drawings, and claims of the present application, various modifications and improvements may be made to the components and / or layout of the subject combination layout. In addition to the modifications and improvements made to the components and / or layout, other uses will also be apparent to those skilled in the art.
