Description

Technical Field

[0001] The utility model relates to the technical field of semi-circular pipe welding, in particular to a semi-circular pipe welding device. Background Technique

[0002] Welding, also known as fusion welding, is a manufacturing process and technology for joining metals or other thermoplastic materials such as plastics by means of heating, high temperature or high pressure. There are many sources of energy for modern welding, including gas flames, electric arcs, lasers, electron beams, friction, and ultrasonic waves. In addition to being used in factories, welding can also be carried out in a variety of environments, such as the wild, underwater, and in space. No matter where it is, welding may pose risks to operators, so appropriate protective measures must be taken during welding. The injuries that welding may cause to the human body include burns, electric shock, vision damage, inhalation of toxic gases, excessive ultraviolet radiation, etc.

[0003] Currently, when welding semi-circular pipes on the market, the semi-circular pipes need to be placed on the top of the position limiting mechanism first. In actual use, when the semi-circular pipes are placed on the top of the position limiting mechanism, at this time, multiple sliding table mechanisms in the welding device drive the guide wheels to perform secondary top limiting on the semi-circular pipes, and then the welding head on the subsequent welding device welds the rotating semi-circular pipes externally. Because the guide wheels on the welding device are relatively close to the welding head, the subsequent guide wheels are easily damaged by welding. Most of the guide wheels are positioned by bolts. The bolts are not rotated for a long time and are prone to rust and seizure problems, which further affects the replacement of the damaged guide wheels, affects the subsequent limiting of the semi-circular pipes, and thus affects the welding of the semi-circular pipes. Content of the Utility Model

[0004] The purpose of the utility model is to provide a semi-circular pipe welding device to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A semi-circular pipe welding device includes an operating rod. A guide plate is fixedly connected to the bottom end of the operating rod. A groove is formed inside the guide plate. A rotating rod is rotatably connected inside the groove. A connecting rod is fixedly connected to the outer wall of the rotating rod. An extrusion block is fixedly connected to one end of the connecting rod. A positioning rod is arranged inside the groove. A pressure-receiving rod is fixedly connected to the outer wall of the positioning rod. An installation groove is formed on the outer wall of the guide plate. One end of the positioning rod penetrates into the installation groove and the positioning rod is rotatably connected to the guide plate. An installation rod is slidably connected inside the installation groove. A positioning groove is formed on the outer wall of the installation rod and one end of the positioning rod is slidably connected to the positioning groove.

[0007] Furthermore, one end of the rotating rod penetrates through the outer wall of the guiding plate and the rotating rod is rotatably connected to the guiding plate. A fixing rod is slidably connected inside the positioning rod. The addition of the fixing rod restricts the movement track of the positioning rod.

[0008] Furthermore, one end of the fixing rod is fixedly connected to the inside of the groove. A spring is provided between the positioning rod and the groove. A guiding wheel is rotatably connected to the outer wall of the mounting rod. The addition of the mounting rod facilitates the replacement of the guiding wheel.

[0009] Furthermore, one end of the operating rod is fixedly connected to a welding head. A first sliding table is provided at the top of the operating rod. A second sliding table is fixedly connected to the bottom end of the first sliding table by a ball nut. The addition of the connecting rod enables the rotating rod to drive the extrusion block to move.

[0010] Furthermore, one side of the outer wall of the second sliding table is fixedly connected to the outer wall of the operating rod by a ball nut. The number of the guiding plates is two. The two guiding plates are symmetrically distributed at the bottom end of the operating rod. The addition of the extrusion block enables the pressure-receiving rod to move inside the groove.

[0011] Furthermore, one end of the spring is fixedly connected to one end of the positioning rod. The other end of the spring is fixedly connected to the inside of the groove. The cross-sectional shape of the positioning groove is circular. The addition of the spring enables the positioning rod to return to its initial position.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] 1. For the semi-circular pipe welding device of the present utility model, the guiding wheel can be conveniently replaced for the second time. By arranging a connecting rod on the outer wall of the rotating rod, arranging an extrusion block at one end of the connecting rod, arranging a fixing rod inside the groove, arranging a positioning rod on the outer wall of the fixing rod, arranging a pressure-receiving rod on the outer wall of the positioning rod, arranging a spring between the positioning rod and the groove, arranging a mounting groove on the outer wall of the guiding plate, and arranging a mounting rod inside the mounting groove, the mounting rod can be moved out of the mounting groove. In the present utility model, when the semi-circular pipe is placed on the top of the position limiting mechanism, at this time, the guiding wheel is driven by a plurality of sliding table mechanisms in the welding device to perform secondary top limiting on the semi-circular pipe, and then the welding head on the subsequent welding device is used to perform external welding on the rotating semi-circular pipe. Since the guiding wheel on the welding device is relatively close to the welding head, the subsequent guiding wheel is easily damaged by the welding. The guiding wheel on this device can be conveniently replaced for the second time, so that the welding of the semi-circular pipe will not be affected.

[0014] 2. The semi-circular pipe welding device of the present utility model can facilitate the limit welding of semi-circular pipes.

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , the present utility model provides a semi-circular pipe welding device, and the technical solution is as follows:

[0023] A semi-circular pipe welding device, comprising an operating rod 1. A guide plate 2 is fixedly connected to the bottom end of the operating rod 1. A groove 3 is formed inside the guide plate 2. A rotating rod 4 is rotatably connected inside the groove 3. A connecting rod 5 is fixedly connected to the outer wall of the rotating rod 4. One end of the connecting rod 5 is fixedly connected to a pressing block 6. A positioning rod 7 is arranged inside the groove 3. A pressure-receiving rod 8 is fixedly connected to the outer wall of the positioning rod 7. An installation groove 9 is formed on the outer wall of the guide plate 2. One end of the positioning rod 7 penetrates inside the installation groove 9 and the positioning rod 7 is rotatably connected to the guide plate 2. An installation rod 17 is slidably connected inside the installation groove 9. A positioning groove 10 is formed on the outer wall of the installation rod 17 and one end of the positioning rod 7 is slidably connected to the positioning groove 10.

[0024] In a preferred embodiment, one end of the rotating rod 4 penetrates the outer wall of the guide plate 2 and the rotating rod 4 is rotatably connected to the guide plate 2. A fixing rod 11 is slidably connected inside the positioning rod 7. When the positioning rod 7 moves, the positioning rod 7 can move on the outer wall of the fixing rod 11, and at the same time, the positioning rod 7 will move inside the groove 3.

[0025] In a preferred embodiment, one end of the fixing rod 11 is fixedly connected to the inside of the groove 3. A spring 12 is arranged between the positioning rod 7 and the groove 3. A guide wheel 13 is rotatably connected to the outer wall of the installation rod 17. When the guide wheel 13 moves, the guide wheel 13 can drive the installation rod 17 to move, so that the installation rod 17 moves inside the installation groove 9.

[0026] In a preferred embodiment, a welding head 14 is fixedly connected to one end of the operating rod 1. A first sliding table 15 is arranged at the top of the operating rod 1. A second sliding table 16 is fixedly connected to the bottom end of the first sliding table 15 by a ball nut. When the rotating rod 4 moves, the rotating rod 4 can drive the connecting rod 5 to move, so that the connecting rod 5 can conveniently drive the pressing block 6 to move.

[0027] Working principle of the utility model: When using this device and needing to replace the guide wheel 13, rotate the rotating rod 4 so that the rotating rod 4 rotates inside the groove 3. The rotating rod 4 will drive the connecting rod 5 to move simultaneously, causing the connecting rod 5 to perform a small circular motion inside the groove 3. The connecting rod 5 will drive the extrusion block 6 to move, making the extrusion block 6 perform a small circular motion inside the groove 3. As a result, the rotating rod 4 can drive the extrusion block 6 to move through the connecting rod 5. The top of the extrusion block 6 is inclined. When the top of the extrusion block 6 contacts the outside of the pressure-receiving rod 8, the inclined surface of the outer wall of the extrusion block 6 will contact the pressure-receiving rod 8, enabling the pressure-receiving rod 8 to slide inside the groove 3. The pressure-receiving rod 8 can drive the positioning rod 7 to move, making the positioning rod 7 slide inside the groove 3. The positioning rod 7 can slide on the outer wall of the fixed rod 11. The positioning rod 7 simultaneously squeezes the spring 12, causing one end of the positioning rod 7 to slide inside the installation groove 9, so that one end of the positioning rod 7 can be separated from the positioning groove 10. When one end of the positioning rod 7 is completely separated from the positioning groove 10, at this time, pull the guide wheel 13 to move, so that the guide wheel 13 can drive the installation rod 17 to move, making one end of the installation rod 17 separate from the installation groove 9. The new guide wheel 13 can drive the installation rod 17 to move, causing one end of the installation rod 17 driving the positioning groove 10 to enter the installation groove 9. At this time, reverse the rotating rod 4 so that the subsequent extrusion block 6 can move away from the pressure-receiving rod 8. At this time, the elastic force of the spring 12 can drive the positioning rod 7 to move, making one end of the positioning rod 7 enter the positioning groove 10, thereby facilitating the replacement of the subsequent guide wheel 13 and not affecting the use of the overall welding equipment by the subsequent guide wheel 13.

[0028] Please refer to Figure 1 and Figure 2 , the utility model provides a technical solution: A ball nut on one side of the outer wall of the second sliding table 16 is fixedly connected to the outer wall of the operating rod 1. The number of guide plates 2 is set to two, and the two guide plates 2 are symmetrically distributed at the bottom end of the operating rod 1. When the extrusion block 6 moves, the extrusion block 6 can drive the pressure-receiving rod 8 to move, enabling the pressure-receiving rod 8 to move inside the groove 3.

[0029] In a preferred embodiment, one end of the spring 12 is fixedly connected to one end of the positioning rod 7, and the other end of the spring 12 is fixedly connected to the inside of the groove 3. The cross-sectional shape of the positioning groove 10 is set to be circular. When the pressure-receiving rod 8 moves, the pressure-receiving rod 8 can drive the positioning rod 7 to move, enabling the positioning rod 7 to squeeze the spring 12.

[0030] Working principle of the utility model: When using this device and needing to weld the semi-circular pipe, place the semi-circular pipe on the top of the position-limiting mechanism at the bottom of the welding equipment at this time. Then drive the operating rod 1 through the subsequent first slide table 15 and second slide table 16, causing the subsequent operating rod 1 to drive the guide wheel 13 through the limiting plate, so that the guide wheel 13 can extrude the outside of the semi-circular pipe. At this time, drive the semi-circular pipe to rotate through the roller at the top of the position-limiting mechanism, causing the subsequent semi-circular pipe to rotate and move on the top of the position-limiting mechanism, thereby facilitating the subsequent welding of the outside of the semi-circular pipe.

[0031] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
