[0024] The following is a clear and complete description of the technical solution of the utility model in conjunction with the accompanying drawings and embodiments. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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.

[0025] Reference Figures 1 to 5 A steel column welding auxiliary device includes a fixed guide rail 1 and an auxiliary bracket, the auxiliary bracket includes a bearing bracket 2, a bracket connector 3 and a handle bracket 4; the bearing bracket 2 is installed on the fixed guide rail 1 and can move along the fixed guide rail 1, the bracket connector 3 is installed at one end of the bearing bracket 2, and the position of the bracket connector 3 can be adjusted, the handle bracket 4 is installed on the bracket connector 3, and the position of the handle bracket 4 can be adjusted.

[0026] Specifically, the fixed guide rail 1 includes a guide rail 1.1, a guide rail threaded screw 1.2, a guide rail fastening nut 1.3 and a guide rail fastening steel plate 1.4, wherein the guide rail threaded screw 1.2, the guide rail fastening nut 1.3 and the guide rail fastening steel plate 1.4 constitute fasteners, and the fasteners are in two groups, which are respectively welded to the bottom of the guide rail 1.1. The guide rail 1.1 is U-shaped galvanized steel, and the two sides of the U-shaped galvanized steel are grooved according to the height of the bearing hole, and the groove width is slightly larger than the diameter of the bearing bracket threaded screw 2.1, and the length of the U-shaped galvanized steel is determined by the size of the on-site steel column.

[0027] Specifically, the bearing bracket 2 includes a bearing bracket threaded screw 2.1, two bearing fixing nuts 2.2 and two bearings 2.3. The two bearings 2.3 are installed at the ends of the bearing bracket threaded screw 2.1. The two bearing fixing nuts 2.2 are respectively located on both sides of the two bearings 2.3 and are used to fix the bearing bracket threaded screw 2.1 and the guide rail 1.1.

[0028] Specifically, the support connector 3 includes two through-thread screw sleeves 3.1 and four matching connecting nuts 3.2, and the two through-thread screw sleeves 3.1 are vertically connected by welding.

[0029] Specifically, the handle bracket 4 includes a handle bracket through-thread screw 4.1, a handle nut 4.2, a handle sleeve 4.3 and a pipe clamp 4.4. The handle sleeve 4.3 is installed at the lower end of the handle bracket through-thread screw 4.1. There are two handle nuts 4.2, which are respectively installed on both sides of the handle sleeve 4.3 for fixing the position of the grip sleeve 4.3. There are two pipe clamps 4.4 for fixing the welding gun handle.

[0030] Installation principle: First, make the welding auxiliary device, connect the bearing bracket 2 and the handle bracket 4 through the bracket connector 3 (the bearing 2.3 and the bearing fixing nut 2.2 of the bearing bracket are not installed first); secondly, put the two bearings 2.3 into the guide rail 1.1 side by side, and install the connected brackets in the order of bearing fixing nut 2.2-guide rail groove-bearing 2.3-guide rail groove-bearing fixing nut 2.2, and rotate the bearing fixing nut 2.2 to ensure that the bearing bracket threaded screw 2.1 and the guide rail 1.1 will not be separated; then, install the guide rail 1.1 on the steel plate that fixes the upper and lower steel columns, and rotate the guide rail fastening nut 1.3 to prevent the guide rail from moving up and down and in the plane, such as Figure 6 As shown; finally, welding is performed using a welding auxiliary device.

[0031] Working principle: Fix the welding gun with a pipe clamp 4.4 on the grip sleeve 4.3 of the installed welding auxiliary device, adjust the connecting nut 3.2 and the grip nut 4.2 to align the welding nozzle with the welding position, and the worker performs welding construction by moving the grip. Since the welding gun is fixed, the weld is semi-automatically constructed along the guide rail to ensure the uniformity of the weld, and the auxiliary device bears most of the weight of the welding gun, reducing the burden on the operators and reducing the quality problems caused by long-term construction. After completing the welding construction on one side, the entire device can be removed for reuse, and only the guide rail, the connector nut and the grip nut need to be fixed.
