DETAILED DESCRIPTION

[0023] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limitations on the present invention. On the contrary, the embodiments of the present invention include all changes, modifications, and equivalents that fall within the spirit and connotation of the appended claims.

[0024] The metal square tube welding and fixing device according to the embodiment of the utility model is described below with reference to the accompanying drawings.

[0025] like Figure 1-Figure 6As shown, the metal square tube welding and fixing device according to the embodiment of the utility model may include a base plate 10 , two support assemblies 20 and a threaded rod 30 .

[0026] The two support assemblies 20 are arranged side by side on the base plate 10 , and each support assembly 20 may include a support seat 21 , a fixing mechanism 22 and a limiting mechanism 23 .

[0027] Among them, the support seats 21 in the two support assemblies 20 are arranged side by side on the base plate 10, and one of the support seats 21 is fixedly connected to the base plate 10, and the other support seat 21 is slidably connected to the base plate 10, that is, by moving the other support seat 21, the two support seats 21 are brought closer to achieve precise docking of the metal square tube.

[0028] The fixing mechanism 22 may include two push plates 221 , a rotating component 222 , two springs 223 and a cover plate 224 .

[0029] Among them, two push plates 221 are slidably arranged on the support seat 21, the rotating component 222 is rotatably arranged in the middle of the support seat 21, two springs 223 are arranged between the two sides of the two push plates 221, the cover plate 224 is arranged on the top of the support seat 21, and the limit mechanism 23 is arranged on the cover plate 224. It can be understood that two springs 63 are arranged between the two push plates 61. When the metal square tube is fixed and clamped, the two push plates 221 are driven to be fixed by rotating the rotating component 222. The characteristics of the spring 63 can be used to push the two push plates 61 in the opposite direction, so that the fixation is more stable.

[0030] One end of the threaded rod 30 is movably connected to one of the support seats 21, and the other end of the threaded rod 30 passes through the other support seat 21 and is connected to the driving handle, that is, the relevant staff drives the threaded rod 30 to rotate by rotating the driving handle, thereby realizing the movement of one of the support seats 21.

[0031] Specifically, when it is necessary to weld the metal square tube, the relevant staff first places the metal square tube welding fixture at the position where welding is required (which may be in a factory building for processing metal plates, steel bars or metal pipes).

[0032] Then, the relevant staff will place the metal square tube on the two support seats 21 respectively, and drive the threaded rod 30 to rotate by rotating the driving handle, so as to realize the movement of one of the support seats 21, so that the two support seats 21 are close to each other, and the metal square tube is accurately docked. The two push plates 221 are driven to fix the metal square tube by rotating the rotating component 222. The characteristics of the spring 63 can be used to push the two push plates 61 in the opposite direction, making the fixation more stable, improving the stability of the welding process, and realizing fast and accurate positioning. This not only improves the welding efficiency, but also ensures the welding quality. At the same time, a single person can complete the positioning welding of the metal square tube, reducing labor costs.

[0033] In one embodiment of the present invention, Figure 5 As shown, the rotating component 222 may include a rotating seat 2221, a rotating rod 2222, a mounting plate 2223, two connecting columns 2224 and two semicircular connecting rods 2225.

[0034] Among them, the rotating seat 2221 is rotatably arranged on the supporting seat 21, the rotating rod 2222 is fixedly connected to the top of the rotating seat 2221, and the other end of the rotating rod 2222 passes through the cover plate 224, the rotating rod 2222 is rotatably connected to the cover plate 224, the mounting plate 2223 is fixedly connected to the outer wall of the rotating rod 2222, the two connecting columns 2224 are respectively fixed on both sides of the mounting plate 2223, and one end of the two semicircular connecting rods 2225 is connected to the two connecting columns 2224, that is, when the rotating rod 2222 rotates, it will drive the mounting plate 2223 to rotate, and when the mounting plate 2223 rotates, it will also drive the two connecting columns 2224 to rotate, and the two connecting columns 2224 rotate and synchronously drive the two semicircular connecting rods 2225 to move.

[0035] In order to clearly explain the above embodiment, in one embodiment of the present utility model, as Figure 5 As shown, the two push plates 221 may include two connecting plates 2211 and two connecting pillars 2212 .

[0037] It can be understood that one end of the two semicircular connecting rods 2225 described in this embodiment is connected to the two connecting columns 2224, and the other end of the two semicircular connecting rods 2225 is connected to the two connecting columns 2212. Therefore, the displacement of the two push plates 221 is achieved by rotating the rotating rod 2222, thereby achieving the fixation of the metal square tube.

[0038] Specifically, when the metal square tube needs to be clamped, the staff needs to rotate the rotating rod 2222. When the rotating rod 2222 rotates, it drives the mounting plate 2223 to rotate. When the mounting plate 2223 rotates, it drives the two semicircular connecting rods 2225 to move, thereby realizing the movement of the two push plates 221 and completing the clamping of the metal square tube.

[0039] Further, in one embodiment of the present invention, Figure 6 As shown, the limiting device 23 may include a connecting block 231 , a handle 232 , a limiting hole 233 and a limiting rod 234 .

[0040] Among them, the connecting block 231 is fixedly connected to the top of the other end of the rotating rod 2222, and one side of the connecting block 231 is fixedly connected to the handle 232. A plurality of limiting holes 233 are arranged on the cover plate 224, and the limiting rod 234 is inserted into the handle 232. The lower ends of the limiting rods 234 are matched with the plurality of limiting holes 233, that is, the limiting rod 234 is first inserted into the handle 232, and then the lower ends of the limiting rods 234 are inserted into the corresponding limiting holes 233, so as to realize the limiting effect on the handle 232 and limit the fixing mechanism 22 at the same time, so that it is not easy to loosen during the clamping process of the metal square tube and the fixing is more secure.

[0041] Further, in one embodiment of the present invention, Figure 2 As shown, square grooves 211 are provided on both sides of the upper ends of the support seats 21 in the two support assemblies 20, that is, the metal square tubes to be welded are placed in the four square grooves 211 respectively, corresponding to each other, so that the two groups of metal square tubes can be welded simultaneously, which greatly increases the work efficiency of the welding work.

[0042] A slide rail 11 is disposed in the bottom plate 10 , a slider 111 is slidably disposed in the slide rail 11 , and one of the support seats 21 in the two support assemblies 20 is connected to the slider 111 .

[0043] It should be noted that the height of the slider 111 described in this embodiment is flush with the top of the base plate 10 to ensure that the heights of the two support seats 21 are consistent, and one of the support seats 21 and the slider 111 are driven to move on the slide rail 11 by rotating the threaded rod 30 .

[0044] In one embodiment of the present invention, Figure 4 As shown, the above-mentioned metal square tube welding and fixing device may further include a push handle 40 and a positioning universal wheel 50.

[0045] Among them, the push handle 40 is arranged on one side of the base plate 10, and the positioning universal wheels 50 are arranged on the four sides of the bottom of the base plate 10, that is, the staff can move the metal square tube welding fixture to the specified position through the push handle 40 and the positioning universal wheels 50.

[0046] It should be noted that the push handle 40 described in this embodiment will not block the square groove 211 and will not affect the welding work of the metal square tube.

[0047] In summary, the metal square tube welding fixture of the embodiment of the utility model can be quickly positioned and installed by a single person, and can weld two groups of metal square tubes at the same time, with high work efficiency. It can provide a more stable fixture, can accurately make the square tubes concentric, and ensure the quality of square tube welding.
