Description

Technical Field

[0001] The utility model relates to the technical field of manufacturing an articulated joint steel pipe assembly, in particular to a manufacturing tool for an articulated joint steel pipe assembly. Background Art

[0002] In the hydraulic piping system, the relative parallelism of the installation surface of the steel pipe assembly is also a very important requirement, especially for the brake steel pipe part. The brake steel pipe part of many models is connected by the brake valve to the steel pipe assembly transition joint and then extended to the brake system at both ends from the transition joint. In this case, the installation parallelism requirements of the steel pipe assembly are very high, because the size and installation surface of the steel pipe assembly are fixed after welding. Any slight deviation in the parallelism of the steel pipe assembly will cause one end to not be locked during installation, resulting in oil leakage and inability to install. That is, the parallelism requirements of the installation surface of the articulated joint steel pipe assembly are high during production. If the deviation of the parallelism of the installation surface is large, it will lead to the inability to lock or install during installation. Therefore, this design is to ensure the parallelism requirements of the installation surface of the steel pipe assembly when the welded parts are not in the same plane. Utility Model Content

[0003] In view of the above-mentioned shortcomings of the prior art, the purpose of the utility model is to provide a manufacturing tool for an articulated joint steel pipe assembly, which is used to solve the problem of large deviation in parallelism of the mounting surface of the manufactured articulated joint steel pipe assembly in the prior art.

This technical solution can fix the steel pipe on the base plate by clamping the steel pipe in the slots on the first positioning block and the second positioning block, thereby facilitating the subsequent production of the articulated joint steel pipe assembly.

[0008] In an embodiment of the present invention, the first positioning block and the second positioning block are located between the positioning pin and the third fixing member, and the first positioning block is located on the side of the positioning pin, and the second positioning block is located on the side of the third fixing member.

[0009] In one embodiment of the utility model, the third fixing member includes a positioning flange for fixing the articulated joint on the base plate and located on the side of the second positioning block, and the positioning flange is provided with a positioning column that matches the shape of the articulated joint and is clamped with the articulated joint. This technical solution can fix the articulated joint on the base plate by clamping the positioning column with the articulated joint, thereby facilitating the subsequent production of the articulated joint steel pipe assembly.

[0010] In one embodiment of the utility model, a first mounting hole threadedly connected to the bottom of the pin is provided on the base plate, and a second mounting hole for installing a positioning flange is also provided on the base plate, and the screw on the positioning flange is threadedly connected to the second mounting hole.

[0011] As described above, the manufacturing tooling of the hinged joint steel pipe assembly of the utility model has the following beneficial effects:

[0012] The first fixing member, the second fixing member and the third fixing member in the utility model are all set according to the assembly dimensions of the articulated joint steel pipe assembly, and under the action of the first fixing member, the second fixing member and the third fixing member, the parts of the articulated joint steel pipe assembly to be welded can be fixed on the manufacturing tooling, so the accuracy of the welding parallelism of the articulated joint steel pipe assembly can be improved during manufacturing, and the tooling can also be used to perform dimensional inspection after the articulated joint steel pipe assembly is manufactured, which fully meets the requirements of more diverse actual piping layout of the articulated joint steel pipe assembly in the hydraulic system, and allows ordinary workers to transfer the control of dimensions to the control of dimensions by tooling, greatly improving the accuracy of product dimensions.
