DETAILED DESCRIPTION

[0021] 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.

[0022] like Figure 1-Figure 2 As shown, a steel component welding auxiliary positioning device includes a collecting groove 101 opened in the middle of the upper surface of the placing platform 1, and support vertical plates 2 are arranged on both sides of the upper surface of the placing platform 1, and two support vertical plates 2 are arranged symmetrically along the middle of the upper surface of the placing platform 1 on both sides, and two limit slide bars 201 are slidably installed on the surface of the support vertical plates 2, and a compression spring 202 is arranged on the side of the outer surface of the limit slide bar 201 away from the middle of the placing platform 1. The advantage of this arrangement is that through the arrangement of the compression spring 202, after the steel component is placed in the middle of the two support frames 203, the limit slide bar 201 can be reset and pulled inward to drive the support frame 203 to move, so that the friction roller 205 contacts the two side surfaces of the steel component to position the steel component, so as to assist the two steel components to dock and avoid displacement during docking.

[0023] Furthermore, a support frame 203 is provided at one end of the limiting slide bar 201 close to the middle of the placement platform 1, and a pull plate 204 is provided on the upper surface of the support frame 203. The advantage of this arrangement is that, through the setting of the pull plate 204, the support frame 203 can be opened by pulling, so as to facilitate the placement of the steel structure.

[0024] Furthermore, a friction roller 205 is rotatably installed on the inner surface of the support frame 203, and the friction roller 205 protrudes from the inner surface of the support frame 203. The advantage of this arrangement is that, through the arrangement of the friction roller 205, when the spiral transmission rod 302 is used to push the steel component, the friction between the steel component and the steel component can be reduced by rolling.

[0025] like Figure 3-Figure 4As shown, limiting slide grooves 3 are provided on both sides of the middle upper surface of the placing platform 1, and support blocks 301 are provided on the upper surfaces of the edges of both sides of the placing platform 1. The middle surface of the support block 301 is spirally installed with a spiral transmission rod 302, and a rotating handle 305 is provided on the opposite end of the spiral transmission rod 302. The advantage of this arrangement is that through the arrangement of the spiral transmission rod 302, the push plate 304 can be driven to slide along the limiting slide groove 3 by means of spiral transmission, so as to push the steel components to align. This structure can stably push the steel components and make the steel components fit more tightly.

[0026] Furthermore, a push plate 304 is provided at the opposite end of the spiral transmission rod 302, and the push plate 304 is set to be slidably connected with the inner surface of the limiting slide groove 3. The advantage of this setting is that the pushing direction of the push plate 304 can be limited by the setting of the limiting slide groove 3.

[0027] Furthermore, two support frames 4 are provided at the gap between the collecting trough 101 and the supporting vertical plate 2, and the upper surface of the support frame 4 is spirally installed with a threaded rod 401, the upper end surface of the threaded rod 401 is installed with a rotating cover 402, and the lower end surface of the threaded rod 401 is installed with a pressure plate 403. The advantage of this arrangement is that through the arrangement of the threaded rod 401, the steel component can be fixed by the pressure plate 403 after the steel component is positioned and contacted.

[0028] Working principle: When using the steel component welding auxiliary positioning device, first, pull the pull plate 204 to drive the support frame 203 to slide along the limit slide bar 201 to increase the gap between the two support frames 203, and then put the steel component between the two support frames 203. After releasing the pull plate 204, the compression spring 202 resets the support frame 203 by pulling the limit slide bar 201 until the friction roller 205 installed on the inner wall of the support frame 203 contacts the steel component to position the steel component, ensuring the alignment of the two relative steel components. Then, by rotating the rotating handle 305, the spiral transmission rod 302 is driven to rotate, so that it pushes the push plate 304 forward to slide along the limit slide groove 3, contact the steel component, and push it to the middle of the placement platform 1 until the two steel components are completely in contact, and then the threaded rod 401 is rotated by the rotating cover 402 to make the pressing plate 403 press the steel component, and then the steel component is welded. This is the working principle of the steel component welding auxiliary positioning device.
