[0028] The technical solutions in the embodiments of the present utility model are clearly and completely described below in conjunction with the accompanying drawings.

[0029] Embodiment 1

[0030] like Figures 1 to 3 As shown, a tower angle steel workpiece welding processing mechanism includes two groups of welding positioning fixtures 1 arranged in a vertical direction, and the welding positioning fixture 1 includes a right-angle seat 12 rotatably set on a base 11, a support unit 13 set on one side of the right-angle seat 12, a limit unit 14 set on one side of the support unit 13 and fitted with one side of the right-angle seat 12, and a push unit 15 slidably set on the right-angle seat 12.

[0031] In this embodiment, by providing two sets of vertical welding positioning fixtures 1, the bending, waste material cutting and assembly welding work are completed in an integrated manner, with a simple structure and high work efficiency.

[0032] Further, if Figure 8 As shown, a guide frame 121 with a semi-open structure is provided at one end of the right-angle seat 12 and a rubber friction portion 122 is provided at the contact portion between the guide frame 121 and the angle steel 100 .

[0033] In this embodiment, by setting a semi-open structure guide frame 121, on the one hand, friction is used to ensure that the angle steel 100 is pushed stably during the pushing process and is not easily offset due to inertia. The movement accuracy of the angle steel is high and the stroke is easy to control; on the other hand, the formed angle steel group is easy to pull out and detach.

[0034] Further, if Figure 6 As shown, the support unit 13 includes a first support seat 131, an elastic support body 132 connected to the base 11 and the outer side of the right-angle seat 12, and a sliding rod 133 fixedly connected to the lower end of the first support seat 131 and slidably arranged on the base 11. The sliding rod 133 moves up and down in the vertical direction under the action of the cylinder 134.

[0035] In this embodiment, by providing the support unit 13, on the one hand, the right-angle seat 12 is supported during the downward bending operation, and after the bending operation is completed, the support body 132 is lowered to support and guide the right-angle seat 12 to reset and rotate.

[0036] It should be noted that the elastic support body 132 drives the right-angle seat 12 to reset during welding, that is, the cylinder 134 drives the sliding rod 133 to move downward, the right-angle seat 12 loses the support of the first support seat 131, and the elastic support body 132 drives the right-angle seat 12 to return to its original position.

[0037] Further, if Figure 1 As shown, the horizontal pushing unit 15 includes a direct driving unit 151 and a driving shaft 152 connected to the direct driving unit 151 .

[0038] In this embodiment, the direct drive unit 151 acts on the angle steel 100 via the driving shaft 152 to complete two horizontal pushing operations of the angle steel 100 .

[0039] It should be noted that the direct drive unit 151 may be driven by a servo motor to drive a rack and pinion, which will not be elaborated herein.

[0040] Further, if Figure 4 As shown, a second support seat 2 is provided on the other side of the right-angle seat 12 relative to the support unit 13 , and the second support seat 2 is fixedly disposed on the base 11 .

[0041] In this embodiment, by setting up the second support seat 2, on the one hand, the right-angle seat 12 is supported during the pressing process of the press, thereby improving the stability of the bending of the angle steel 100; on the other hand, the second support seat 2 limits the right-angle seat 12 when it rotates and resets, so that the right-angle seat 12 can be accurately in place after rotating 45°.

[0042] Furthermore, a welding machine is arranged between the two groups of right-angle seats 12 at vertical positions.

[0043] Further, if Figure 1 to Figure 2 As shown, a cutting machine is arranged between the welding machine and the right-angle seat 12 and a collecting box 4 is arranged below the cutting machine.

[0044] It is worth mentioning that the waste triangular pieces on the cut angle steel 100 automatically fall into the collection box 4 for collection.

[0045] Furthermore, a press is provided above the right-angle seat 12 .

[0046] Embodiment 2

[0047] like Figure 7 As shown, the components identical or corresponding to those in the first embodiment are marked with the corresponding reference numerals in the first embodiment. For the sake of simplicity, only the differences from the first embodiment are described below. The second embodiment differs from the first embodiment in that:

[0048] Furthermore, the limiting unit 14 includes a side plate 141 , a baffle 142 rotatably disposed on the base 11 , and a tension spring 143 with one end connected to the baffle 142 and the other end connected to the side plate 141 .

[0049] In this embodiment, by setting a limit unit 14, the outer edge of the right-angle seat 12 is limited whether in the pressing process or in the process of rotating the right-angle seat 12 to a vertical angle, so as to prevent the angle steel 400 from shaking after forming, and protect the angle steel from falling outward and shifting during the shaking process, thereby improving the welding accuracy.

[0050] Working process:

[0051] First, two sets of steel plates 200 are placed on the right-angle seat 12, and then the press is started to press downward, and two sets of angle steels 100 are formed;

[0052] Next, the support unit 13 is started, and the support unit 13 drives the right-angle seat 12 to rotate 45° through the linkage 16;

[0053] Then, the horizontal push unit 15 is started, and the horizontal push unit 15 pushes the angle steel 100 to move forward a certain distance to the cutting machine, and the cutting machine cuts off the triangular part 300 of the angle steel and automatically drops it into the collection box 4;

[0054] Finally, the push unit 15 continues to push the angle steel 100 forward to the welding machine. After the welding machine completes the automatic splicing and welding of the two groups of angle steels 100, it pulls up and separates the entire right-angle angle steel 400 from the right-angle seat 12.

[0055] In the description of the present invention, it should be understood that the terms "front and back", "left and right", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the equipment or components referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the utility model.

[0056] Of course, in the present technical solution, those skilled in the art should understand that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the element may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0057] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art under the technical guidance of the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
