Description

Technical Field

[0001] The utility model relates to the technical field of pipe welding, and specifically relates to a pipe welding tooling. Background Technique

[0002] During the welding process, the workpiece and the solder melt to form a molten area, and after the molten pool cools and solidifies, a connection between the materials is formed. The seam formed during welding and connecting two connected bodies is called a weld seam.

[0003] When two butt-jointed pipes are welded, it is necessary to weld around the seam in a circle. To increase the convenience of welding, Patent CN212043348U discloses a welding tooling for aluminum alloy pipes. The pipes at both ends are fixed by clamping blocks, and the motor can drive the pipes to rotate, thus facilitating the welding of the entire circle of the pipes. However, this device fixes one end of the pipe through a clamping block. When the pipe is relatively long, only fixing one end of the two pipes cannot ensure the stability during the butt-joint of the pipes, and it is very easy to cause the misalignment of the butt-joint ends of the two pipes, affecting the welding quality.

Detailed implementation manner

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] As Figure 1-2 shown, a welding tooling for a pipe 5 includes a base 1. A support member 3 is provided at the upper end of the base 1. A pipe 5 is supported by two support members 3. As Figure 3 shown, the support member 3 includes a support block 302. The lower end of the support block 302 is connected to the base 1 through a support rod 301. A V-shaped groove for supporting the pipe is provided on the upper end surface of the support block 302. A pressing member 4 for pressing the pipe 5 is provided above the base 1. The pressing member 4 is located between the two support members 3. As Figure 4 shown, the pressing member 4 includes a pressing block 401 that can move up and down. A V-shaped groove matching the pipe is provided on the lower end surface of the pressing block 401. Positioning mechanisms 2 for positioning the ends of the pipe 5 are provided at both ends of the base 1.

[0024] In order to enable the pipe 5 to rotate, support rollers 6 are provided in the V-shaped groove.

[0025] A column 107 is connected to one side of the base 1. A cross beam 106 is vertically connected to the upper end of the column 107. The upper end of the pressing block 401 is rotatably connected to a third lead screw 402 that is threadedly engaged with the cross beam 106 and a guide rod 404 that penetrates the cross beam 106. A third handle 403 is provided at the upper end of the third lead screw 402. By rotating the third lead screw 402 with the third handle 403, the up and down movement of the pressing block 401 can be realized, thereby realizing the pressing of the pipe 5.

[0026] The positioning mechanism 2 includes a sliding seat 206 connected to the base 1. A moving rod 203 is connected to the upper end of the sliding seat 206. A second lead screw 202 is connected to the moving rod 203. One end of the second lead screw 202 is provided with a second handle 201, and the other end of the second lead screw 202 is connected to a positioning plate 205. The positioning plate 205 positions one end of the pipe 5.

[0027] To facilitate the rotation of the pipe 5, a collar 204 is provided on the side wall of the positioning plate 205. The end of the second lead screw 202 is connected to the collar 204 through a bearing. One end of the pipe 5 abuts against the positioning plate 205. The rotation of the pipe 5 can drive the positioning plate 205 to rotate, thereby reducing friction.

[0028] To increase the universality of use, the left and right positions of the positioning mechanism 2 can be adjusted. A guide rail 102 is fixed to the upper end of the base 1. A first lead screw 104 is provided above the guide rail 102. The end of the first lead screw 104 is connected to the guide rail 102 through a fixing block 101. One end of the first lead screw 104 is connected to a first handle 105. The lower end of the sliding seat 206 is matched with the guide rail 102 through a slider 103. The sliding seat 206 is matched with the first lead screw 104 through a nut seat.

[0029] During use, the two pipes 5 are respectively placed on the upper ends of the two supporting blocks 302. The welding ends of the two pipes 5 are butted. Rotate the first handle 105 to make the positioning plate 205 abut against the end of the pipe 5 to position the pipe 5 and prevent the pipe 5 from sliding left and right. Rotate the third handle 403 to make the pressing block 401 press on the upper end of the pipe 5 to fix the pipe 5 and prevent the pipe 5 from jumping during welding. During the welding process, the pipe 5 can be directly rotated to achieve a full-circle welding.

[0030] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalent technologies, the present invention also intends to include these changes and modifications.
