[0002] A T-shaped steel component includes a cross beam, and a vertical beam is welded at the center position of the bottom surface of the cross beam. In the manufacturing process of this T-shaped steel component, the cross beam and the vertical beam need to be welded. However, during the current welding operation, usually workers hold it by hand or use two jigs to cooperate to straighten it, and then weld it. However, there is currently no special tooling for assisting in the fixed welding of the cross beam and the vertical beam of this T-shaped steel component, which is not conducive to reducing the labor intensity of workers and improving work efficiency. Summary of the Invention

[0003] Aiming at the deficiencies of the prior art, the utility model provides a welding tooling for steel components, which can fix and splice the cross beam and the vertical beam of the T-shaped steel component to be welded, facilitating subsequent welding work, and effectively solving the problems raised in the background technique.

[0004] To achieve the above purpose, the utility model provides the following technical solution: A welding tooling for steel components, including a U-shaped fixing frame. At the center position of the inner bottom surface of the U-shaped fixing frame, a square box body with an upward opening is fixedly provided. At the upper part of the U-shaped fixing frame, U-shaped clamping seats with inward openings are respectively fixedly provided. One side of the parallel part of the U-shaped clamping seat is screwed inward with a limit bolt.

[0005] At the center position of the bottom surface of the U-shaped fixing frame, a column is fixedly provided. The column is rotatably inserted into the lower base, and a limit structure cooperating with the base is fixedly provided on one side of the bottom of the U-shaped fixing frame.

[0006] As a preferred technical solution, the base is in the shape of a flat cylinder, and a circular groove is embedded at the center position of the upper surface. A bearing cooperating with the column is provided in the circular groove.

[0007] As a preferred technical solution, the limit structure includes a cross plate. The inner end of the cross plate is fixedly connected to the side surface of the U-shaped fixing frame. A bolt is slidably inserted through the cross plate from top to bottom. A tension spring is sleeved on the bolt above the cross plate. The upper end of the tension spring is fixedly connected to the bottom surface of the convex part of the bolt, and the lower end of the tension spring is fixedly connected to the upper surface of the cross plate.

[0008] The bottom surface of the bolt is in a downward convex arc structure, and arc grooves cooperating with the arc structure are respectively provided on the front and rear sides of the upper surface of the base.

[0009] As a preferred technical solution, the inner width of the U-shaped clamping seat is greater than the inner diameter of the square box body.

[0010] As a preferred technical solution, rubber blocks are respectively fixed to the inner ends of the limit bolts.

[0011] As a preferred technical solution, universal wheels with a limiting function are respectively fixed to the four corners of the bottom surface of the base.

[0012] Compared with the prior art, the present utility model provides a steel member welding tooling, which has the following beneficial effects:

[0013] 1. In the present utility model, a square box body with an upward opening is fixedly arranged at the center of the inner bottom surface of the U-shaped fixing frame, and U-shaped clamping seats with inward openings are respectively fixedly arranged at the upper ends of the U-shaped fixing frame. A limit bolt is screwed inward on one side of the parallel part of the U-shaped clamping seat. During use, the square box body is used to insert the bottom of the vertical beam of the T-shaped steel member therein, so as to fix the vertical beam. The cross beam can be placed on the U-shaped clamping seats at the upper end of the U-shaped fixing frame and fixed and limited by the limit bolt, so that the vertical beam and the cross beam are spliced, facilitating the staff to weld the connection between the cross beam and the vertical beam. Compared with manual grasping, it can effectively reduce the labor intensity of the staff and improve the efficiency at the same time. Compared with two jigs, the structure is also simplified and the cost is reduced.

[0014] 2. In the present utility model, a column is fixedly arranged at the center of the bottom surface of the U-shaped fixing frame, and the column can be rotatably inserted into the base below. A limiting structure cooperating with the base is fixedly arranged on one side of the bottom of the U-shaped fixing frame. During use, the U-shaped fixing frame can be circumferentially flipped and adjusted in direction through the column, which is beneficial for welding on both sides, and the limiting structure can fix and limit the U-shaped fixing frame.

[0015] 3. In the present utility model, a bolt penetrates through the horizontal plate from top to bottom and slides. A tension spring is sleeved on the bolt above the horizontal plate. The upper end of the tension spring is fixedly connected to the bottom surface of the protruding part of the bolt, and the lower end of the tension spring is fixedly connected to the upper surface of the horizontal plate. The bottom surface of the bolt is in a downward convex arc structure, and arc-shaped grooves cooperating with the arc structure are respectively arranged on the front and rear sides of the upper surface of the base.

A square box body 11 with an upward opening is fixedly provided at the center of the inner bottom surface of the U-shaped fixing bracket 1. U-shaped clamping seats 12 with inward openings are respectively fixedly provided at the upper ends of the U-shaped fixing bracket 1. A limiting bolt 121 is screwed inward on one side of the parallel part of the U-shaped clamping seat 12. A column 13 is fixedly provided at the center of the bottom surface of the U-shaped fixing bracket 1. The column 13 is rotatably inserted into the lower base 2. A limiting structure 3 cooperating with the base 2 is fixedly provided on one side of the bottom of the U-shaped fixing bracket 1.

[0027] The base 2 is a flat cylinder, and a circular groove 21 is embedded at the center of the upper surface. A bearing 22 cooperating with the column 13 is provided in the circular groove 21.

[0028] The limiting structure 3 includes a cross plate 31. The inner end of the cross plate 31 is fixedly connected to the side surface of the U-shaped fixing frame 1. A bolt 32 is slidably arranged through the cross plate 31 from top to bottom. A tension spring 33 is sleeved on the bolt 32 above the cross plate 31. The upper end of the tension spring 33 is fixedly connected to the bottom surface of the protruding part of the bolt 32, and the lower end of the tension spring 33 is fixedly connected to the upper surface of the cross plate 31. The bottom surface of the lower end of the bolt 32 is in a downward convex arc structure 34. Arc-shaped grooves 23 that cooperate with the arc structure 34 are respectively arranged on the front and rear sides of the upper surface of the base 2.

[0029] The width inside the U-shaped card seat 12 is greater than the diameter inside the square box body 11.

The cross beam 42 can be placed on the U-shaped card seat 12 at the upper end of the U-shaped fixing frame 1 and is fixedly limited by the limiting bolts 121, so that the vertical beam 41 and the cross beam 42 are spliced, facilitating the staff to weld the connection between the cross beam 42 and the vertical beam 41. Through the column 13, the U-shaped fixing frame 1 can be circumferentially rotated to adjust the direction, which is beneficial to welding on both sides of the workpiece. The limiting structure 3 can fixedly limit the U-shaped fixing frame 1. Specifically, the arc structure 34 cooperates with the arc-shaped groove 23 under the pressing action of the tension spring 33 to play a role in limiting the U-shaped fixing frame 1. Rotate the U-shaped fixing frame 1, and the arc structure 34 disengages from the arc-shaped groove 23 until it is in limiting cooperation with the arc-shaped groove 23 on the other side, and plays a limiting role for the U-shaped fixing frame 1 again.
