Description

Technical Field

[0001] The utility model relates to the field of welding fixing devices, in particular to a steel structure welding fixing device. Background Art

[0002] Steel structure is a structure made of steel materials and is one of the main types of construction structures. The structure is mainly composed of beams, steel columns and other components made of steel sections and steel plates. Rust removal technology is used, and these structures are usually connected by welds, bolts or rivets.

[0003] At present, most of the factories are made of steel structures, and the steel materials (steel plates, steel columns) are fixed and connected by welding. However, in the prior art, it is necessary to manually fix the two steel materials during welding, which is relatively cumbersome. It takes two to three people to weld the two steel materials, which is time-consuming and labor-intensive, and there are safety hazards. Some manufacturers use fixing clamps to clamp and fix the steel materials, but the fixed steel materials cannot be rotated or turned over. During welding, only one side of the two steel materials can be welded, and the other side needs to loosen the clamp, turn the two steel materials over, and then use the clamp to fix and weld the steel materials again, which is inconvenient to operate and has low efficiency.

[0004] Therefore, it is necessary to invent a steel structure welding fixture. Utility Model Content

[0005] The purpose of the utility model is to solve the problems raised in the above background technology.

[0006] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a steel structure welding fixing device, comprising a first fixing plate and a second fixing plate, the first fixing plate and the second fixing plate are symmetrically arranged, an adjustment component is installed on one side of the first fixing plate and the second fixing plate, a support is installed on the side of the first fixing plate and the second fixing plate close to the adjustment component, a fixing clamp is installed on the side of the first fixing plate and the second fixing plate away from the support, a support plate is installed between the first fixing plate and the second fixing plate, and an anti-slip component is installed on the upper end of the support plate.

[0007] Based on the above characteristics: the support can support and fix the first fixed plate and the second fixed plate. When the steel needs to be welded and fixed, the distance between the first fixed plate and the second fixed plate is adjusted in advance according to the length of the steel, and then one end of the two steels is respectively inserted into the fixing clamps on one side of the first fixed plate and the second fixed plate. Then, according to the diameter of the steel, the fixing clamp can be adjusted through the adjustment component to facilitate the fixing clamp to clamp steels of different diameters. At the same time, the side of the steel away from the fixing clamp will be placed above the support plate, and the ends of the two steels close to the support plate will be aligned with each other, and then the anti-slip component is used to limit and fix the steel above the support plate. Finally, the welding gun can be used to weld the ends of the two steels that are fitted. During the welding process, the first fixed plate and the second fixed plate can drive the two steels to rotate synchronously, which is convenient for all-round welding of the steel without the need for reciprocating disassembly and assembly.

[0008] Preferably, the first fixed plate and the second fixed plate have the same structure, are symmetrically arranged on both sides of the support plate, a positioning seat is fixedly installed on one side of the first fixed plate and the second fixed plate, and limiting grooves are symmetrically provided on the surfaces of the first fixed plate and the second fixed plate.

[0009] Based on the above features: the first fixed disk and the second fixed disk are connected and fixed to the support through the positioning seat, so that when the first fixed disk and the second fixed disk rotate, the support will be in a fixed state.

[0010] Preferably, the adjustment assembly includes a convex plate and forward and reverse screws installed in the middle of the convex plate, and movable nuts are threadedly connected to the outer sides of the forward and reverse screws, and a limiting plug is fixedly installed on one side of the movable nut.

[0011] Based on the above characteristics: when the forward and reverse screws rotate, the movable nuts on both sides can be driven to move, and one side of the movable nut is movable through the limit slot through the limit plug, which not only allows the movable nut and the limit plug to maintain translation, but also the limit plug can drive the fixed clamp to move and adjust.

[0012] Preferably, a hole is provided in the middle of the upper end of the support, and a driving motor is installed on one side of the upper end of the support.

[0013] Based on the above features: when the driving motor is started, the positioning seat can be driven to rotate through the rotating shaft, and the positioning seat will also synchronously drive the first fixed disk and the second fixed disk to rotate.

[0014] Preferably, the fixing fixture is composed of two symmetrical semi-arc plates.

[0015] Based on the above features: two symmetrical semi-arc plates are fixedly connected to one end of two limit plugs respectively. When the limit plugs move, the limit plugs will synchronously drive the two symmetrical semi-arc plates to move closer to or away from each other, so that steels of different diameters can be clamped and fixed.

[0016] Preferably, a V-shaped groove is provided in the middle of the upper end of the support plate, a movable hole is provided on the surface of the V-shaped groove, and a ball is movably arranged inside the movable hole.

[0017] Based on the above characteristics: one end of the steel away from the first fixed plate and the second fixed plate is placed on the inner side of the V-shaped groove, and the surface of the steel will contact the balls on the inner wall of the V-shaped groove. When the first fixed plate and the second fixed plate drive the steel to rotate through the fixing clamp, rolling friction will also be formed between the steel and the balls, reducing the resistance of the steel during rotation and avoiding wear on the steel surface.

[0018] Preferably, the anti-slip assembly includes a top plate and a fixing nut installed in the middle of the top plate, a locking screw is threadedly connected in the middle of the fixing nut, a pressure block is installed at the lower end of the locking screw, and a roller is provided at the bottom of the pressure block.

[0019] Based on the above features: the top plate is fixed above the V-groove, and then the locking screw is rotated to drive the pressure block downward so that the roller at the bottom of the pressure block contacts the surface of the steel. This can not only limit the upper part of the steel to prevent the steel from escaping from the V-groove, but also when the steel rotates, rolling friction will be formed between the steel and the roller to prevent damage to the steel.

[0020] The beneficial effects of the utility model are:

[0021] 1. When the steel needs to be welded and fixed, the distance between the first fixing plate and the second fixing plate is adjusted in advance according to the length of the steel, and then one end of the two steels is respectively inserted into the fixing clamps on one side of the first fixing plate and the second fixing plate. Then, according to the diameter of the steel, the fixing clamp can be adjusted by adjusting the assembly to facilitate the fixing clamp to clamp steels of different diameters. At the same time, the side of the steel away from the fixing clamp will be placed above the support plate, and the ends of the two steels close to the support plate will be aligned with each other, and then the anti-slip assembly is used to limit and fix the steel above the support plate. Finally, the welding gun can be used to weld the ends of the two steels that are fitted. During the welding process, the driving motor can drive the positioning seat to rotate, and the positioning seat will also synchronously drive the first fixing plate and the second fixing plate to rotate, which is convenient for all-round welding of steels without the need for reciprocating disassembly and fixation.

[0022] 2. When one end of the steel is placed in the V-groove, the surface of the steel will contact the ball on the inner wall of the V-groove. Then the top plate can be fixed on the top of the V-groove, and then the locking screw is rotated to drive the pressure block to move down, so that the roller at the bottom of the pressure block contacts the surface of the steel. This can not only limit the upper part of the steel to prevent the steel from escaping from the V-groove, but also when the steel rotates, rolling friction can be formed between the steel and the ball, and rolling friction will also be formed between the steel and the roller, reducing the resistance of the steel during rotation and avoiding wear on the steel surface.

When one end of the steel is fixed, The other end will be placed in the V-groove 61 above the support plate 6. At this time, the top plate 71 can be rotated to reach the top of the V-groove 61, and then the other side of the top plate 71 can be fixed.
