Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figure 1 As shown:

[0028] An angle steel welding fixture includes a base 102 and two sets of angle steel frames 101 disposed above the base 102.

[0029] In this implementation plan: In order to solve the technical problems existing in the prior art, such as the background art disclosed above, "when welding and connecting two sets of angle irons, the existing clamps are generally used to clamp and fix them. The existing clamps are generally used to fix the angle irons with bolts, and then welding is performed. The method of fixing the angle irons is cumbersome and reduces the effectiveness of the device." In combination with the use, this problem is obviously a real problem that is difficult to solve.

[0030] Furthermore:

[0031] like Figures 1-3 As shown:

[0032] Based on the above: the base 102 is equipped with two sets of side plate frames 103;

[0033] A connecting plate 104 is provided between the two sets of side panel frames 103;

[0034] The upper surface of the connecting plate 104 is fixed with symmetrically arranged support plates 105;

[0035] A right-angled locking block 106 is fixed to the upper surface of the support plate 105;

[0036] The two inclined surfaces of the right-angle block 106 are provided with electromagnet plates 107 that are magnetically attracted by the diagonal steel frame 101;

[0037] Angle steel frame 101 is placed on the surface of right angle block 106. The surface of right angle block 106 is provided with an installation groove that matches the electromagnet piece 107. The electromagnet piece 107 is located in the installation groove and is fixedly connected to the right angle block 106. The surface of the electromagnet piece 107 is flush with the inclined surface of right angle block 106.

[0038] In this embodiment: When using the angle steel welding fixture, firstly, the right-angled surface of the angle steel frame 101 is placed on the surface of the right-angle block 106, so that the right angle of the angle steel frame 101 corresponds to the right angle of the edge of the right-angle block 106, thereby positioning the angle steel frame 101. Then, the two sets of angle steel frames 101 are pushed and the corresponding sides of the two sets of angle steel frames 101 are aligned. Then, the electromagnet plate 107 is energized, and the angle steel frame 101 is magnetically attracted and fixed by the magnetic attraction force generated by the electromagnet plate 107. Then, the connection between the two sets of angle steel frames 101 is welded and fixed by personnel using welding equipment (not shown in the figure).

[0039] This operation uses the magnetic attraction force generated by the electromagnet 107 to align and fix the two sets of angle steel frames 101, eliminating the need to use bolts to press and fix the angle steel frames 101. This makes fixing the angle steel frames 101 more convenient, improves the effectiveness of the device, and meets actual usage needs.

[0040] It should be noted that a rechargeable battery is fixed at the bottom of the connecting plate 104 to supply power to the electromagnet plate 107.

[0041] Furthermore;

[0042] In an optional embodiment, a rotation locking mechanism 2 is installed between the connecting plate 104 and the two sets of side plate frames 103. The angle of the connecting plate 104 can be adjusted by the rotation locking mechanism 2, so that the two sets of angle steel frames 101 can be adjusted to different positions for welding.

[0043] The rotary locking mechanism 2 includes fixed shafts fixed on both sides of the connecting plate 104, a rotating disk 201 fixed on the surface of one set of fixed shafts, and locking grooves 202 arranged in a ring at equal intervals at the edge of the rotating disk 201. The fixed shafts on the connecting plate 104 are rotatably mounted by bearings and side plate frame 103.

[0044] One of the side plate frames 103 has a rectangular hole 205 on one side, and a swing lock rod 203 is installed in the rectangular hole 205. One end of the swing lock rod 203 is fixed with a rotating shaft, and the rotating shaft is rotatably connected to the side plate frame 103 through a bearing. A reset torsion spring 204 is wound around the surface of the rotating shaft. The two ends of the reset torsion spring 204 are fixedly connected to the side plate frame 103 and the swing lock rod 203 respectively. The other end of the swing lock rod 203 is locked in one of the lock slots 202 opened in the rotating disk 201.

[0045] A top rod 206 is fixed on the surface of the side plate frame 103 to block and position the swing locking rod 203.

[0046] In this embodiment: After the welding of the outer surface of the connection of the angle steel frame 101 is completed, the swing locking rod 203 is then turned. At this time, the swing locking rod 203 drives the rotating shaft to rotate, and at the same time drives the return torsion spring 204 to generate torsional deformation until the other end of the swing locking rod 203 disengages from the locking groove 202, thereby releasing the lock on the rotating disk 201. Then the connecting plate 104 is rotated, which drives the right angle block 106 and the angle steel frame 101 to rotate synchronously, so that the angle steel frame 101 flips to the back. Then the swing locking rod 203 is released. At this time, the return torsion spring 204 rebounds and resets, and locks the swing locking rod 203 in the corresponding locking groove 202 to lock the position of the rotating disk 201. Through this operation, the angle of the angle steel frame 101 can be adjusted, and the welding of the connection of the two sets of angle steel frames 101 can be more complete.

[0047] Furthermore;

[0048] In an optional embodiment, a lifting mechanism 3 is installed between the two sets of side plate frames 103 and the base 102;

[0049] The lifting mechanism 3 includes a U-shaped rod 301 that slides on one side of the base 102, a fixed plate 302 fixed to the two ends of the U-shaped rod 301, and a spring 303 wound around the two ends of the U-shaped rod 301.

[0050] The two ends of the spring 303 are fixedly connected to the base 102 and the fixed plate 302 respectively. Multiple sets of equally spaced slots 304 are opened on one side of the surface of the side plate frame 103. The two ends of the U-shaped rod 301 are inserted into one of the slots 304 opened on the surface of the two sets of side plate frames 103.

[0051] The upper surface of the base 102 is provided with a limiting groove that matches the side plate frame 103. The side plate frame 103 and the base 102 are slidably connected through this limiting groove. The surface of the base 102 is provided with a through hole that matches the U-shaped rod 301. The U-shaped rod 301 and the base 102 are slidably connected through this through hole.

[0052] In this embodiment: During welding, pulling the U-shaped rod 301 stretches the spring 303, causing the U-shaped rod 301 to disengage from the slot 304, releasing the lock between the base 102 and the side plate frame 103. Then, pushing the connecting plate 104 causes the side plate frame 103 to slide up and down on the base 102 until the connecting plate 104 reaches a certain height. Afterward, the U-shaped rod 301 is released, causing the spring 303 to rebound and insert both ends of the U-shaped rod 301 into the corresponding slots 304, thus locking the base 102 and the side plate frame 103 in place. This operation allows for height adjustment of the connecting plate 104, thereby adjusting the height of the angle steel frame 101 to accommodate different heights, facilitating welding operations and further improving the practicality and flexibility of the device.

[0053] The working principle and usage process of this utility model are as follows: When using this angle steel welding fixture, firstly, the right-angled surface of the angle steel frame 101 is placed on the surface of the right-angle block 106, so that the right angle of the angle steel frame 101 corresponds to the right angle of the edge of the right-angle block 106, thereby positioning the angle steel frame 101. Then, the two sets of angle steel frames 101 are pushed, aligning their corresponding sides. Next, the electromagnet 107 is energized, and the magnetic attraction generated by the electromagnet 107 magnetically attracts and fixes the angle steel frame 101. Finally, personnel use welding equipment (not shown in the figure) to weld the connection between the two sets of angle steel frames 101. This operation aligns and fixes the two sets of angle steel frames 101 using the magnetic attraction force generated by the electromagnet 107, eliminating the need for bolts to compress and fix the angle steel frames 101. This method of fixing the angle steel frames 101 is more convenient, improves the effectiveness of the device, and meets practical application requirements. After welding the outer surface of the connection point of the angle steel frames 101, the swing locking rod 203 is then turned. At this time, the swing locking rod 203 drives the rotating shaft to rotate, and at the same time, it drives the return torsion spring 204 to generate torsional deformation until the other end of the swing locking rod 203 disengages from the locking groove 202, thereby releasing the lock on the rotating disk 201. Then, the connecting plate 10 is rotated. 4. This causes the right-angle locking block 106 and the angle steel frame 101 to rotate synchronously, causing the angle steel frame 101 to flip to the back. Then, the swing locking rod 203 is released, and the return torsion spring 204 rebounds and resets, locking the swing locking rod 203 in the corresponding locking groove 202 to lock the position of the rotating disk 201. Through this operation, the angle of the angle steel frame 101 can be adjusted, allowing for more complete welding at the connection between the two sets of angle steel frames 101. During welding, by pulling the U-shaped rod 301, the spring 303 is stretched, causing the U-shaped rod 301 to disengage from the slot 304, releasing the lock between the base 102 and the side plate frame 103. The connecting plate 104 is then pushed, causing the side plate frame 103 to slide up and down on the base 102 until the connecting plate 104 rises to a certain height. Then the U-shaped rod 301 is released, and the spring 303 rebounds, inserting both ends of the U-shaped rod 301 into the corresponding slots 304 to lock the positions of the base 102 and the side plate frame 103. Through this operation, the height of the angle steel frame 101 can be adjusted by adjusting the height of the connecting plate 104, so that the height of the angle steel frame 101 can be flexibly adjusted according to people of different heights, so as to better perform welding operations on the angle steel frame 101 and further improve the practicality and flexibility of the device.
