Technical Field

[0001] The utility model relates to the technical field of fastening high-precision small-diameter pipe sections, in particular to a matching pipe clamp for fastening high-precision small-diameter pipe sections. Background Art

[0002] Small-diameter precision pipes are small-diameter seamless pipes with high dimensional accuracy and good surface finish used in mechanical structures and hydraulic equipment.

[0003] In the pipeline manufacturing industry, small-diameter pipes sometimes need to be welded after production. Therefore, some fasteners that are easy to weld have begun to enter the public's field of vision. However, the fasteners available on the market today have relatively complex structures, which leads to relatively high costs. In addition, they are not convenient to carry when needed, which results in low efficiency and accuracy when aligning small-diameter pipes with holes.

[0004] Therefore, we provide a high-precision small-diameter pipe clamp for fastening. Utility Model Content

There are two steel plates in total. A mounting rod is installed on one side surface of the steel plate, and a limiting nut is installed at one end of the mounting rod. A positioning bolt is installed inside the limiting nut.

[0007] Preferably, the positioning bolt is threadedly screwed into the limiting nut, a nut is installed on the upper end of the positioning bolt, a buffer is installed on the end of the positioning bolt away from the nut, and the mounting rod is fixedly installed on one side surface of the steel plate.

[0014] 1. The utility model uses steel plates to make double U-shaped pipe clamps as supporting surfaces, which are installed by welding angle steels to the double pipe clamps. The pipe sections to be matched are placed on the angle steels to act on the pipe clamp limit pipe to displace them. The two pipe sections to be welded are determined by the center line plate as to whether they are centrally positioned in the pipe clamp limit pipe. The mounting rod is installed at the end on the other side of the pipe clamp, and the limit nut is installed at the upper end of the mounting rod.

There are two steel plates 1 in total. A mounting rod 3 is installed on one side surface of the steel plate 1. A limiting nut 6 is installed at one end of the mounting rod 3. A positioning bolt 4 is installed inside the limiting nut 6. When the high-precision small-diameter pipe segment matching tool is manufactured, the steel plate 1 is made into a double U-shaped pipe clamp as a supporting surface, and the double pipe clamp is connected and installed by welding the angle steel 9. The pipe segment to be matched is placed on the angle steel 9 to act on the pipe clamp limiting pipeline to move. The two pipe segments to be welded are determined by the center line plate 10. As for the pipe clamp limiting pipeline, After the clamp is centered, the mounting rod 3 is installed at the end on the other side of the pipe clamp, and the limiting nut 6 is installed at the upper end of the mounting rod 3. A positioning bolt 4 of the same specification and model is inserted into the limiting nut 6. The positioning bolt 4 is adjusted to fall by continuously rotating the nut 7 until the buffer 8 installed at one end of the positioning bolt 4 is firmly clamped and fastened to the welded pipe section, thereby achieving the effect of precise matching of the pipe sections. The tool has low production cost, is convenient and fast, safe and reliable, solves the problem of low efficiency in matching small-diameter pipe sections, and improves the efficiency and installation accuracy of pipe matching operations.

The mounting rod 3 is fixedly installed on one side surface of the steel plate 1. The presence of the buffer 8 can ensure that the tip of the positioning bolt 4 does not cause damage to the pipe end surface. The presence of the mounting rod 3 can ensure the installation fixity of the limiting nut 6 and avoid the limiting nut 6 from falling off during long-term use.

[0027] like Figures 1-4 As shown, the steel plate 1 is fixedly installed on the lower surface of the angle steel 9, the upper surface of the angle steel 9 is installed with a first protection pad 13, the upper surface of the angle steel 9 is installed with a second protection pad 11, and the surface of the angle steel 9 is plugged with a center plate 10. The first protection pad 13 and the second protection pad 11 are made of special rubber material, which can protect the pipe section placed on the surface of the angle steel 9 and avoid damage to the surface of the welded pipe section during tightening and clamping. When the pipe sections are matched, the welded pipe section can be placed in the center position of the matching device through the center plate 10. After the matching is completed, the center plate 10 is pulled out and welding can be performed, which has the effect of determining the welding position.

[0029] like Figures 1-4 As shown, a support block 2 is fixedly installed on the lower surface of the steel plate 1, and a vertical protective pad 12 is installed on the upper surface of the angle steel 9. The vertical protective pad 12 and the angle steel 9 are fixedly installed. The support block 2 is set to support the steel plate 1, and the steel plate 1 can be placed firmly and horizontally on the ground. The solid vertical protective pad 12 can form a wrapping protection effect for the pipe section together with the first protective pad 13 and the second protective pad 11, thereby avoiding damage to the surface of the welded pipe section during tightening, clamping and welding, thereby playing a protective effect.

As for the pipe clamp limit pipe, it must not be placed in the middle position. The installation rod 3 is installed at the end of the other side of the pipe clamp, and the limit nut 6 is installed at the upper end of the installation rod 3. The positioning bolt 4 of the same specification and model is inserted into the limit nut 6. By continuously rotating the nut 7, the positioning bolt 4 is adjusted to fall until the buffer 8 installed at one end of the positioning bolt 4 is firmly clamped and tightened with the welded pipe section, thereby achieving the effect of precise matching of the pipe sections. The tool has low production cost, is convenient and fast, safe and reliable, and solves the current problem of low efficiency in matching small-diameter pipe sections, and improves the efficiency and installation accuracy of pipe section matching operations. The presence of the buffer 8 can ensure that the tip of the positioning bolt 4 does not cause damage to the pipe end surface, and the presence of the installation rod 3 can ensure the installation fixity of the limit nut 6, avoiding the problem of long During the long-term use, the limit nut 6 may fall off. The first protection pad 13 and the second protection pad 11 are made of special rubber material, which can protect the pipe section placed on the surface of the angle steel 9, avoiding damage to the surface of the welded pipe section during tightening and clamping. When the pipe sections are matched, the center line plate 10 can be used to place the welded pipe section in the middle position of the matching device. After the matching is completed, the center line plate 10 can be pulled out and welding can be carried out, which has the effect of determining the welding position. The surface of 9 is provided with a plug-in hole 18, which can enable the plug-in rod 16 on the lower surface of the first protection pad 13 and the second protection pad 11 to form a plug-in structure with the plug-in hole 18, thereby achieving an installation effect. The support block 2 is provided to support the steel plate 1, and the steel plate 1 can be placed firmly and horizontally on the ground.
