Description

Technical Field

[0001] The utility model relates to the technical field of welding clamps, in particular to a steel pipe welding clamp for steel structure buildings. Background Art

[0002] Steel pipe is a commonly used building material in the construction industry. It plays an important role in constructing building frames. Using steel pipes to construct house frames in the construction industry requires welding of the steel pipes. When welding, the steel pipes need to be aligned at a certain angle, so clamps are needed to clamp and fix the steel pipes.

[0003] The existing clamps used for welding steel pipes in steel structure buildings generally fix the two steel pipes in a vertical state or in a horizontally connected state. It is difficult to adjust the welding angle of the two steel pipes according to different construction requirements. As a result, when the two steel pipes are welded at different angles, workers need to fix them by hand, which easily leads to deviations in the welding of the steel pipes. In view of this, we propose a steel pipe welding clamp for steel structure buildings. Utility Model Content

[0007] The angle adjustment mechanism includes a long axis and a screw B; the long axis is arranged between the two clamping mechanisms, one end of the screw B is limited and rotated with the bottom of the long axis through a limit sleeve, a movable sleeve is sleeved on the surface of the screw B, and two connecting rods are symmetrically arranged on both sides of the screw B, and the two sides of the movable sleeve are respectively rotatably connected to one end of the two connecting rods through a rotating shaft, and the other ends of the two connecting rods are respectively rotatably connected to the bottom surfaces of the two L-shaped clamps through a rotating shaft.

[0008] Preferably, the L-shaped clamps in the two clamping mechanisms are fixedly connected to sleeves at opposite ends through connecting plates, and the sleeve on one of the L-shaped clamps is located above the sleeve on the other L-shaped clamp, and the two sleeves are both sleeved on the surface of the long axis, and a T-shaped groove is provided on the L-shaped clamp.

[0021] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0022] Example:

[0023] This embodiment discloses a steel pipe welding fixture for steel structure buildings, see Figures 1 to 5 , including two symmetrically arranged clamping mechanisms 1 and an angle adjustment mechanism 2.

[0024] like Figures 1 to 5 As shown, the clamping mechanism 1 includes an L-shaped clamping plate 101, one end surface of the L-shaped clamping plate 101 is fixedly connected to a fixed seat 102, a movable clamping plate 103 is provided between the fixed seat 102 and the L-shaped clamping plate 101 and is concave toward the fixed seat 102, a screw A104 is threadedly connected to the fixed seat 102, one end of the screw A104 is rotatably connected to the surface of one side of the movable clamping plate 103, and the other end of the screw A104 is fixedly connected to a handwheel A105; two steel pipes to be welded are respectively placed between the L-shaped clamping plate 101 and the movable clamping plate 103 in the two clamping mechanisms 1, and the handwheel A105 is rotated to drive the screw A104 to rotate on the fixed seat 102, and the movable clamping plate 103 is pushed close to the L-shaped clamping plate 101 to clamp the steel pipes.

[0025] Specifically, Figures 1 to 3 As shown, the angle adjustment mechanism 2 includes a long axis 201 and a screw B202; the long axis 201 is arranged between the two clamping mechanisms 1, one end of the screw B202 is limited and rotated with the bottom of the long axis 201 through a limiting sleeve, a movable sleeve 203 is sleeved on the surface of the screw B202, and two connecting rods 204 are symmetrically arranged on both sides of the screw B202, and the two sides of the movable sleeve 203 are respectively rotatably connected to one end of the two connecting rods 204 through a rotating shaft, and the other ends of the two connecting rods 204 are respectively rotatably connected to the bottom surfaces of the two L-shaped clamps 101 through the rotating shaft; when the screw B202 is rotated, since the two ends of the two connecting rods 204 are respectively rotatably connected to the movable sleeve 203 and the L-shaped clamp 101, a limiting effect is generated on the movable sleeve 203 in the vertical direction, so that the movable sleeve 203 can be delayed to move along the screw B202, and the two L-shaped clamps 101 are pulled or pushed apart or aggregated by the two connecting rods 204.

[0026] Further, such as Figures 1 to 4As shown, the opposite ends of the L-shaped clamps 101 in the two clamping mechanisms 1 are fixedly connected with sleeves 106 through connecting plates, and the sleeve 106 on one of the L-shaped clamps 101 is located above the sleeve 106 on the other L-shaped clamp 101, and the two sleeves 106 are both sleeved on the surface of the long axis 201. A T-shaped slide groove 1011 is provided on the L-shaped clamp 101. One end of the two L-shaped clamps 101 is rotatably connected to the long axis 201 through the sleeve 106. When the two connecting rods 204 pull or push the two L-shaped clamps 101, the two L-shaped clamps 101 will be dispersed or aggregated on both sides with the long axis 201 as the axis, thereby adjusting the welding angle of the two steel pipes on the two L-shaped clamps 101.

[0027] Further, if Figure 4 As shown, a T-shaped slider 1031 adapted to the T-shaped slide groove 1011 is provided at the bottom of the movable clamp plate 103 , and the T-shaped slider 1031 is slidably connected to the T-shaped slide groove 1011 to enhance the stability of the movable clamp plate 103 moving on the L-shaped clamp plate 101 .

[0028] It is worth noting that if Figure 5 As shown, a plurality of threaded holes 1032 are provided on the movable clamp plate 103, and a friction column 1033 is connected to the inner thread of the threaded hole 1032. Since the surface of the steel pipe is an arc surface, the design of multiple friction columns 1033 is conducive to increasing the contact area with the surface of the steel pipe, and increasing the friction between the steel pipe and the movable clamp block 103. At the same time, the friction column 1033 is installed through the threaded hole, which is convenient for the replacement of the friction column 1033 after long-term wear.

[0029] It is worth noting that Figures 1 to 3 As shown, the other end of the screw rod B202 is fixedly connected to a hand wheel B205 to facilitate the rotation of the screw rod B202.

[0030] Working principle: When the utility model is used, two steel pipes to be welded are placed between the L-shaped clamping plate 101 and the movable clamping plate 103 in the two clamping mechanisms 1, and the hand wheel A105 is turned to drive the screw A104 to rotate on the fixed seat 102, and the movable clamping plate 103 is pushed toward the L-shaped clamping plate 101 through the T-shaped slider 1031 and the T-shaped slide groove 1011, so that the friction column 1033 contacts the surface of the steel pipe, and the steel pipe is clamped and fixed. The hand wheel B205 is turned. Since the two ends of the two connecting rods 204 are separated, the movable clamping plate 103 is pushed toward the L-shaped clamping plate 101 through the T-shaped slider 1031 and the T-shaped slide groove 1011. The two connecting rods 204 are rotatably connected with the movable sleeve 203 and the L-shaped clamping plate 101, thereby limiting the movable sleeve 203 in the vertical direction, and allowing the movable sleeve 203 to move backward along the screw B202. When the two connecting rods 204 pull or push the two L-shaped clamping plates 101, the two L-shaped clamping plates 101 will be dispersed or aggregated on both sides with the long axis 201 as the axial direction, thereby adjusting the welding angle of the two steel pipes on the two L-shaped clamping plates 101. After adjusting the angle of the two steel pipes, the two steel pipes can be welded.

[0031] The embodiments of the present invention disclose preferred embodiments, but are not limited thereto. A person skilled in the art can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. However, as long as they do not deviate from the spirit of the present invention, they are all within the protection scope of the present invention.
