Problems solved by technology

Although the gantry-type machining center is basically a 60m double-station structure, the use of an isolated fixture design will prevent the fixture from being completely spread out.
If multiple machine tools are used, when the order quantity is insufficient, each machine tool will be "not full", reducing the equipment utilization rate

Embodiment 1

[0033] like figure 1 As shown, a combination fixture for rail vehicle machining is composed of 4 A unit modules and 16 B unit modules (not fully shown) arranged in parallel, and the A unit module is located on the outside of the B unit module.

[0034] like figure 2 As shown, the A unit module includes the beam platform 8, the floor machining fixture, the overall machining fixture after the roof is welded, and the long and large section machining fixture. The overall machining jig is set on the left and right sides of the long and large bar machining jig, and the floor machining jig is set on the outside of the overall machining jig after the roof is welded;

[0035] like image 3 As shown, the B unit module includes the beam platform 8, the overall machining fixture after the roof is welded and the long and large section machining fixture. The long and large section machining fixture is set in the middle of the beam platform 8, and the overall machining fixture after the r...

Abstract

The invention provides a combined rail vehicle machining fixture, which includes a floor machining fixture, a roof welding overall machining fixture, a long and large material machining fixture and a beam platform. The whole tooling is composed of 20 unit modules. Units 1-4 are composed of 5 small modules at the beginning, and other unit modules are composed of three small modules. The small T-slot module in the middle is responsible for the support and clamping of long and large-scale machining. , and can meet the profile processing of different sections by changing the support module. The small fixture modules on both sides of the T-shaped slot are mainly used for the overall machining of the roof after welding. The invention is easy to operate and accurate in positioning, solves the trouble of lifting and transporting the tooling back and forth, improves the utilization rate of the machine tool, overcomes the problem of insufficient flexibility in the layout of the existing subway vehicle machining process, ensures the progress of the project, and the flexible design It makes the tooling convenient for later transformation, and only needs to modify the simple support and compression module to adapt to the production of different types of products.

Description

technical field [0001] The invention relates to a rail vehicle manufacturing device, in particular to a rail vehicle machining combination fixture. Background technique [0002] The subway vehicles mainly adopt type A and type B. The overall length of type A is about 22m, and that of type B is about 19m. The train and high-speed rail can reach about 25m. In order to complete the processing of large parts of the vehicle, a gantry type machining center is used. The processing area of ​​these machine tools is required to be more than 30m to ensure that there is enough tire space for component fixtures. Although the gantry-type machining center is basically a 60m double-station structure, the use of an isolated fixture design will prevent the fixture from being completely spread out. If multiple machine tools are used, when the order quantity is insufficient, each machine tool will be "not full", which will reduce the utilization rate of equipment. [0003] The processing sp...
