Description

Technical Field

[0001] This utility model relates to the field of bending pipe welding, specifically to an auxiliary positioning device for bending pipe welding. Background Technology

[0002] Welding, also known as fusion welding, is a manufacturing process and technology that joins metals or other thermoplastic materials such as plastics by heating, high temperature, or high pressure. Welding includes plate welding, pipe welding, and container welding. Pipe welding technology includes welding curved pipes. Currently, many large processing plants use automated welding technology for welding curved pipes. However, in some small welding plants, curved pipe welding is still done manually. This requires clamping and fixing the two curved pipes to be welded. Currently, there is no dedicated positioning device for clamping and fixing curved pipes, which causes some inconvenience for welders and is detrimental to improving work efficiency. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides an auxiliary positioning device for welding bent pipes. This device can position and splice bent pipes so that workers can manually weld them, thereby improving work efficiency.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary positioning device for welding bent pipes, including a worktable, the worktable being a flat cuboid shape, with legs provided at the four corners of the bottom surface, and inverted T-shaped slides provided at the upper surface of the worktable in a cross shape, with clamping members that can be slidably arranged in the slides and have adjustable angles in the circumferential direction.

[0005] The clamping component includes a slider that mates with a slide rail. The slider is inverted T-shaped. A rotating shaft is vertically rotatably inserted at the top center of the vertical portion of the slider. A fixing component that mates with a curved pipe is fixedly provided at the top of the rotating shaft. A fixing seat is provided on the side of the vertical portion of the rotating shaft. A fastening bolt for pressing the rotating shaft is screwed into the fixing seat from the outside to the inside. An anti-slip nut is also provided on the screw on the inner side of the outer end of the fastening bolt.

The first clamping plate and the second clamping plate are hinged at one end, and the other end is respectively provided with a horizontal fixing block. The fixing blocks are connected together by a bolt from bottom to top, and the protruding end of the bolt is provided with a locking nut.

[0007] As a preferred technical solution, the inner surfaces of the first clamping plate and the second clamping plate are respectively provided with a rubber layer.

[0008] As a preferred technical solution, the vertical portion of the slider is provided with a through hole on one side to cooperate with the fastening bolt.

A fastening bolt for pressing the shaft is screwed into the fixing seat from the outside to the inside. An anti-slip nut is also provided on the screw on the inner side of the outer end of the fastening bolt. In use, the fixing component can be adjusted in angle by rotating the vertical shaft circumferentially, and the shaft can be positioned by the fastening bolt. The anti-slip nut can limit the fastening bolt and prevent it from loosening.

[0014] 3. This utility model includes a first clamping plate with a lower convex arc shape and a second clamping plate with an upper convex arc shape on the upper side of the first clamping plate.

[0026] Example 1

[0027] like Figures 1 to 4As shown, an auxiliary positioning device for welding bent pipes includes a worktable 1, which is a flat cuboid with legs 11 at the four corners of its bottom surface. The upper surface of the worktable 1 has inverted T-shaped slides 2 (vertical sections are inverted T-shaped). Clamping members 3, adjustable in circumferential angle, are slidably mounted in the slides 2. Each clamping member 3 includes a slider 31 that mates with the slides 2. The slider 31 is inverted T-shaped. A rotating shaft 33 is vertically rotatably inserted at the center of the top of the vertical portion 32 of the slider 31. A fixing member 34, which mates with the bent pipe, is fixed to the top of the rotating shaft 33. A fixing seat 35 (cuboid) is provided on one side of the vertical portion of the rotating shaft 33. A fastening bolt 36, which presses against the rotating shaft 33, is screwed onto the fixing seat 35 from the outside in. An anti-slip nut 37 is also provided on the inner side of the protruding portion at the outer end of the fastening bolt 36.

[0028] The fastener 34 includes a first clamping plate 341 with a lower convex arc shape on the lower side, and a second clamping plate 342 with an upper convex arc shape on the upper side of the first clamping plate 341. The first clamping plate 341 and the second clamping plate 342 are hinged at one end, and the other end is provided with a horizontal fixing block 343. The fixing blocks 343 are connected together with a bolt 344 passing through from bottom to top. The protruding end of the bolt 344 is provided with a locking nut 345.

[0030] The vertical portion of the slider 31 has a through hole (not shown) that mates with the fastening bolt 36.

[0031] In use, the curved pipes to be welded are clamped and fixed in the fixing parts 34. The splicing position can be adjusted by sliding the slider 31 in the slide rail 2, and the clamping parts 3 can be rotated circumferentially to adjust the angle, which facilitates the splicing of the curved pipes 4 (41 is the weld seam, and the rest is the curved part). After splicing, it can also be limited to facilitate manual welding by the workers. Specifically, the fixing parts 34 can be rotated circumferentially to adjust the angle by the vertical rotating shaft 33, and the rotating shaft 33 can be positioned by the fastening bolt 36. The anti-slip nut 37 can limit the fastening bolt 36 to prevent it from loosening. The curved pipe 4 can be placed in the lower first clamping plate 341, and then the second clamping plate 342 can be flipped downward and locked and fixed by the bolt 344 and the locking nut 345. The two clamping plates can be replaced according to the outer diameter of the curved pipe (connected to the rotating shaft 33) to accommodate various models of curved pipes 4.

[0032] Example 2

[0033] like Figure 5 As shown, the inner end of the fastening bolt 36 is pointed 361, and the side of the rotating shaft 33 is provided with a vertical strip groove 331 that is matched with the pointed 361 for positioning.

[0034] In use, the pointed tip 361 and the grooved groove 331 work together to better limit the position of the rotating shaft 33.

[0035] Example 3

[0036] like Figure 6 As shown, limit blocks 5 (cubic-pole shaped) are respectively provided on the worktables 1 at both ends of the slide 2. The limit blocks 5 are connected to the worktables 1 by limit bolts 51.

[0037] When in use, the limiting block 5 can limit the clamping part 3 at both ends of the slide 2 to prevent it from sliding out from both ends of the slide 2.
