Description

Technical Field

[0001] This utility model belongs to the field of guide rail technology, and specifically relates to a guide rail for an automatic pipe welding machine. Background Technology

[0002] The guide rail used in the automatic pipe welding machine has a ring-shaped structure, which is fitted onto the pipe. It has ring-shaped teeth that mesh with the teeth on the welding trolley, allowing the trolley to move circumferentially around the pipe. Elastic elements are spaced apart on the inner surface of the rail, making elastic contact with the pipe to reduce vibration and increase stability. The two ends of the rail are deformable for easy assembly and disassembly. A fixing mechanism, such as a screw and nut pair, enables rapid positioning and fixation, improving welding efficiency and quality.

[0003] Chinese patent with announcement number "CN207806962U" discloses a pipe external welding guide rail, including a first ring rail and a second ring rail installed on the pipe and arranged in parallel at intervals. The first ring rail and the second ring rail are both spliced ​​together by two semi-circular ring bodies. A wedge-shaped band is fixedly provided on the outer surface of the semi-circular ring body. The first ring rail and the second ring rail are connected by a number of track connecting blocks that are distributed at intervals. These track connecting blocks are arranged in parallel and at equal intervals along the circumference of the ring rail. One end of each track connecting block is fixedly connected to the inner surface of the first ring rail.

[0004] However, the above structure still has some shortcomings. When welding the pipes, since the volumes of different pipe models are different, while the limiting structure of the guide rail is fixed, the limiting welding can only be performed on pipes that match the guide rail, which reduces the practicality of the guide rail.

A drive motor 14 is fixedly connected to one side of the pipe body 9, and a pressure plate 15 is installed on the other side of the drive motor 14. The position of the pressure plate 15 corresponds to the position of the pipe body 9. In use, the first limiting frame 1 facilitates the placement of the pipe body 9. The spring seat 4 pulls down elastically, thereby effectively clamping the two pipe positions. The welding hole 7 facilitates the user to weld the joint of the pipe body 9. To facilitate all-round welding, the user can turn the screw 20, and the rotating shaft 19 can make the end of the screw 20 rotate in place, while the joint plate 11 will be pushed or pulled, so that the pressure plate 15 can be pressed against one side of the pipe body 9. The outer side of the pipe body 9 is provided with a bearing structure. When the drive motor 14 is started to drive the pressure plate 15 to rotate, the pressure plate 15 can also drive the pipe body 9 to rotate together, thereby making the welding point of the pipe body 9 rotate, thus achieving the effect of all-round welding of the pipe body 9, which can effectively improve the practicality of the guide rail and the welding efficiency.

[0023] refer to Figure 1 The top of the first limiting frame 1 is fixedly connected to the first telescopic rod 3, and the top of the first telescopic rod 3 is fixedly connected to the bottom of the second limiting frame 5. The spring seat 4 is located on the side close to the first telescopic rod 3. The first telescopic rod 3 includes a movable rod and a sleeve rod. The movable rod is sleeved inside the sleeve rod. Due to the presence of the first telescopic rod 3, the first telescopic rod 3 can provide secondary support and traction to the bottom of the second limiting frame 5 without hindering the pull-down of the second limiting frame 5, thereby effectively improving the stability of the pull-down of the second limiting frame 5.

[0024] refer to Figure 3Rubber pads 8 are fixedly connected to the inner walls of the first limiting frame 1 and the second limiting frame 5. The thickness of the rubber pads 8 is five millimeters. The rubber pads 8 cover the inner walls of the first limiting frame 1 and the second limiting frame 5. The inner side of the rubber pads 8 is in contact with the outer side of the pipe body 9. Due to the presence of the rubber pads 8, the rubber products have good anti-slip ability and rubber cushioning ability, which can effectively improve the stability of the pipe body 9 in position clamping, and at the same time prevent the outer wall of the pipe body 9 from being bumped.

[0025] refer to Figure 1 and Figure 2 A third telescopic rod 21 is fixedly connected to one side of the connecting block 25. One side of the third telescopic rod 21 is fixedly connected to the other side of the docking plate 11. The screw 20 is located on the inner side close to the third telescopic rod 21. The structure of the third telescopic rod 21 is the same as that of the first telescopic rod 3. Due to the presence of the third telescopic rod 21, the third telescopic rod 21 can provide secondary support and traction to the other side of the mounting frame 12 without hindering the adjustment of the mounting frame 12 position, thereby effectively improving the stability of the mounting frame 12 position adjustment.

[0026] refer to Figure 2 A first groove 16 is provided on the other side of the pressure plate 15. A first anti-slip pad 17 is fixedly connected to the inner side of the first groove 16. The other side of the first anti-slip pad 17 is on the same horizontal line as the other side of the pressure plate 15. The first anti-slip pad 17 is made of rubber material and covers the inner side of the first groove 16. Due to the presence of the first anti-slip pad 17, the first anti-slip pad 17 can effectively increase the friction on the other side of the pressure plate 15, thereby making the pressure plate 15 press more stably, so as to improve the stability of driving the pipe body 9 to rotate.

[0027] refer to Figure 4 The bottom end of the support leg 2 is fixedly connected to a base 22, which covers the bottom end of the support leg 2. A second groove 23 is provided at the bottom end of the base 22. A second anti-slip pad 24 is fixedly connected to the inner side of the second groove 23, which covers the inner side of the second groove 23. The second anti-slip pad 24 is made of rubber material. Due to the presence of the base 22, the bottom end of the support leg 2 can be effectively supported. The anti-slip pad can effectively improve the anti-slip ability of the bottom end of the base 22, thereby effectively improving the stability of the first limiting frame 1.

[0028] refer to Figure 1 Both the first limiting frame 1 and the second limiting frame 5 have a reinforcing layer inside. The reinforcing layer inside the first limiting frame 1 and the second limiting frame 5 is made of aluminum alloy. Due to the presence of the reinforcing layer, the reinforcing layer can effectively improve the overall strength of the first limiting frame 1 and the second limiting frame 5, so as to improve their service life.

[0029] Operating principle and advantages: During use, the first limiting frame 1 facilitates the placement of the pipe body 9. The elastic pull of the spring seat 4 effectively clamps the two pipe positions. The welding hole 7 allows the user to weld the joint of the pipe body 9. For convenient all-around welding, the user can turn the screw 20, causing the rotating shaft 19 to rotate the end of the screw 20 in place. This pushes or pulls the docking plate 11, allowing the pressure plate 15 to press against one side of the pipe body 9. The outer side of the pipe body 9 has a bearing structure. When the drive motor 14 is started, it rotates the pressure plate 15, which in turn rotates the pipe body 9, thus rotating the welding point of the pipe body 9. This achieves all-around welding of the pipe body 9, effectively improving the practicality of the guide rail and welding efficiency. Due to the presence of the first telescopic rod 3, it can provide secondary support to the bottom of the second limiting frame 5 without hindering the pull-down of the second limiting frame 5. The support and traction effectively improve the stability of the second limiting frame 5 when pulled down. Due to the presence of the rubber pad 8, the rubber products have good anti-slip and rubber buffering capabilities, which can effectively improve the stability of the pipe body 9 in the clamping position, and at the same time prevent the outer wall of the pipe body 9 from being bumped. Due to the presence of the third telescopic rod 21, the third telescopic rod 21 can provide secondary support and traction on the other side of the mounting frame 12 without hindering the adjustment of the mounting frame 12 position, which can effectively improve the stability of the mounting frame 12 position adjustment. Due to the presence of the first anti-slip pad 17, the first anti-slip pad 17 can effectively increase the friction on the other side of the pressure plate 15, which can make the pressure plate 15 press more stably, so as to improve the stability of driving the pipe body 9 to rotate. Due to the presence of the base 22, the bottom end of the support leg 2 can be effectively supported. The anti-slip pad can effectively improve the anti-slip capability of the bottom end of the base 22, which can effectively improve the stability of the first limiting frame 1 in the position.
