Description

Technical Field

[0001] The utility model relates to the technical field of welding, in particular to a welding torch guiding device for corrugated plate welding. Background Art

[0002] A welding torch guiding device is an auxiliary tool used in the welding process to ensure that the welding torch can move accurately and stably to the established welding points. Through the guidance of the device, the consistency of the weld seam and the stability of the quality can be achieved. The application of this tool has greatly improved the automation level and operation convenience of the welding process.

[0003] After investigation, a Chinese utility model patent discloses a welding device for corrugated plates (publication number: CN210997204U), which includes a welding torch, a slide rail and a cross beam. The slide rail is arranged vertically, and the slide rail is vertically arranged on one side of the cross beam through a lifting and sliding mechanism, and the slide rail moves horizontally on the cross beam through the lifting and sliding mechanism. A walking guiding mechanism is arranged at the bottom of the slide rail, switch magnetic seats are arranged at both ends of the cross beam, and a welding torch swinging mechanism is installed on one side of the upper part of the slide rail through a fixing frame, and the output end of the welding torch swinging mechanism is connected to the welding torch.

[0004] In the above patent, rollers are used as the guiding mechanism of the welding torch, and the welding torch is driven in real time by the sliding track of the rollers on the surface of the corrugated plate. This guiding method has certain limitations. Since there is a certain distance between the rollers and the welding torch, when the corrugated plate is deformed due to the force generated by the extrusion of the rollers on the surface of the corrugated plate, the flatness of the area where the corrugated plate rollers slide may be different from that of the welding area. At this time, this guiding method will cause the problem of inaccurate welding of the welding torch.

[0005] Therefore, the utility model provides a welding torch guiding device for corrugated plate welding to solve the above problems. Summary of the Utility Model

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments 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 in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] The utility model provides a corrugated plate welding torch guiding device, such as Figure 1 and Figure 2 As shown, the guiding device comprises a connecting plate 1, a welding gun 9 rotatably mounted at the bottom of the connecting plate 1, and a guiding mechanism arranged at the top of the connecting plate 1;

[0026] The guiding mechanism includes a connecting column 2 fixedly installed on the top of the connecting plate 1, a spring 4 fixedly connected to the top of the connecting column 2, a first limit frame 3 fixedly connected to the connecting column 2, a sleeve 5 slidably connected to the connecting column 2, a second limit frame 6 fixedly connected to the inside of the sleeve 5 and in contact with the connecting column 2, and a top plate 7 fixedly connected to the top of the sleeve 5, and one end of the spring 4 away from the connecting column 2 is fixedly connected to the bottom of the top plate 7.

[0027] Since the corrugated plate as a whole is in a periodic undulation shape, the guiding device of the welding gun should guide the welding of the welding gun in real time according to the undulation of the corrugated plate, and the top plate 7 is fixed on a stable or movable mechanism so that the welding gun 9 fits the welding point of the corrugated plate. The connecting column 2 arranged on the top of the welding gun 9 moves inside the casing 5, and a spring 4 is installed between the connecting column 2 and the top plate 7. When the corrugated plate or the device moves, the welding gun 9 can move vertically in real time when it is squeezed by the undulating force of the corrugated plate surface, and welding is carried out at the same time. The second limit frame 6 inside the casing 5 is used to resist the first limit frame 3 on the connecting column 2, thereby reducing the probability of the casing 5 and the connecting column 2 being detached.

[0028] Furthermore, in order to enable the welding gun 9 to rotate, a fixed plate 8 is fixedly connected to the bottom of the connecting plate 1, and a rotating block 10 inserted into the fixed plate 8 is fixedly installed on the welding gun 9. The fixed plate 8 is provided with a circular groove for the rotating block 10 to rotate.

[0029] The circular groove formed on the fixing plate 8 is adapted to fit the rotating block 10 , and the welding gun 9 is rotated by the rotating block 10 .

[0030] Further, in order to adjust the angle of the welding gun 9, as shown in Figure 1 , Figure 2 and Figure 3 , a connecting block 14 is fixedly connected to the outer wall of the welding gun 9, and a connecting shaft 13 is fixedly connected inside the connecting block 14.

[0031] A threaded rod 12 is rotatably connected to the connecting block 14 through the connecting shaft 13, and the threaded rod 12 penetrates through the connecting plate 1.

[0032] One side of the welding gun 9 is connected to the threaded rod 12 through the connecting block 14. When the threaded rod 12 is lifted or pressed down, the other side of the welding gun 9 is also pressed down or lifted accordingly, thereby realizing the adjustment of the angle.

[0033] It should be noted that, in order to facilitate the operation of the threaded rod 12, as shown in Figure 1 , Figure 2 and Figure 3 , an adjusting block 11 is screwed onto the threaded rod 12.

[0034] When the adjusting block 11 rotates in place, the threaded rod 12 engaged by the internal thread can perform vertical movement.

[0035] Furthermore, in order to facilitate the rotation of the adjusting block 11, as shown in Figure 1 and Figure 3 , the adjusting block 11 is movably connected inside the connecting plate 1, and a circular groove for the adjusting block 11 to rotate is formed on the connecting plate 1.

[0036] The adjusting block 11 is installed inside the connecting plate 1. Due to its own I-shaped shape, the adjusting block 11 can stably rotate inside the connecting plate 1.

[0037] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
