Description

Technical Field

[0001] This utility model relates to the technical field of machining positioning fixtures, and in particular to a positioning fixture for machining double-tube bending. Background Technology

[0002] In the field of metal pipe processing, pipe bending is a key step in manufacturing complex pipeline systems. Because pipe bending involves the simultaneous bending and forming of pipes, it places higher demands on positioning accuracy, processing efficiency, and forming quality.

[0003] For example, in existing pipe bending processing fixtures, such as the patent with authorization announcement number CN205129438U, there is a fixture for processing the beveling of connecting pipe fittings. It is set on a conventional lathe for processing the beveling of connecting pipe fittings to clamp the connecting pipe fittings to be processed. The fixture includes a base that slides along the lathe track, a lower fixture, and an upper fixture. The lower fixture is fixedly set on the base. One side of the upper fixture is rotatably connected to the lower fixture, and the opposite side is provided with a fixing plate with a notch.

[0004] During use, it was found that the clamp could only hold and fix one pipe at a time, and it was not easy to adjust the pipe after clamping it, which increased the limitation of use and reduced the efficiency of pipe processing. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a double-pipe bending positioning fixture that improves the convenience of bending two pipes at once, increases the efficiency of single-pipe bending by 50% compared with the existing single-pipe bending, and improves the convenience of automatic pipe conveying and rotational adjustment of bending direction.

The two sets of side clamping members are positioned on both sides of the central clamping member via the moving device, and the central clamping member and the two sets of side clamping members are respectively provided with semi-circular grooves at their relative positions. The adjusting device is located on the top of the base and is used for conveying and rotating the pipes. The bracket is mounted on the top of the base, and the guide rollers are rotatably mounted on the outer wall of the bracket. Two pipes are placed on both sides of the central clamping member, and the moving device moves the two sets of side clamping members to their positions, so that the two sets of side clamping members cooperate with the central clamping member to clamp and fix the two pipes. Then, the two pipes can be bent, improving the convenience of bending two pipes at once. Compared with the existing single-pipe bending process, the efficiency is increased by 50%. The adjusting device conveys and rotates the two pipes, improving the convenience of automatic pipe conveying and rotation adjustment of the bending direction.

[0007] Preferably, the adjusting device includes a driving device, a power device, two sets of bases, two sets of cylinders, multiple sets of first guide columns, multiple sets of first hydraulic cylinders, and multiple sets of clamping plates.

The two sets of motors are respectively mounted on the outer walls of the two sets of bases, the two sets of gears are respectively mounted on the output ends of the two sets of motors, and the two sets of gear rings are respectively mounted on the outer walls of the two sets of cylinders. The two sets of gear rings mesh with the two sets of gears. The two sets of motors drive the two sets of gears to rotate, so that the two sets of gears drive the two sets of cylinders to rotate by meshing with the two sets of gear rings.

[0009] Preferably, the moving device includes two sets of second hydraulic cylinders and multiple sets of second guide columns. The two sets of second hydraulic cylinders are mounted on the outer wall of the base, and the multiple sets of second guide columns are slidably mounted on the base. The two sets of second hydraulic cylinders and the multiple sets of second guide columns are respectively connected to two sets of side clamping members. By controlling the two sets of second hydraulic cylinders to drive the two sets of side clamping members to move, the convenience of the two sets of side clamping members in clamping the pipe is improved.

[0010] Preferably, the power unit includes a guide rail and two sets of third hydraulic cylinders. The guide rail is mounted on the base, the two sets of bases are slidably mounted on the guide rail, and the two sets of third hydraulic cylinders are mounted on the outer side wall of the base.

[0011] Preferably, it also includes a V-groove, which is set on the outer wall of the guide roller; by setting the V-groove, the limiting effect of the guide roller on the pipe conveying is improved.

[0012] Preferably, it also includes an anti-slip pad, which is disposed on the outer wall of the multiple sets of clamps; to improve the anti-slip effect of the multiple sets of clamps on the pipe.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: two pipes are placed on both sides of the central clamping member, and the two sets of side clamping members are moved by the moving device so that the two sets of side clamping members cooperate with the central clamping member to clamp and fix the two pipes. Then the two pipes can be bent. This improves the convenience of bending two pipes at once and increases the efficiency by 50% compared with the existing single pipe bending process. The two pipes are transported and rotated by the adjusting device, which improves the convenience of automatic pipe transport and rotation adjustment of the bending direction.
