Embodiment Construction

[0011] refer to figure 1 , 2 , the present invention is made up of TC car positioning frame body 1, MC car positioning frame body 2, accompanying frame body, supporting leg 11, support 10, curved beam positioning body 8, pressing block 9, edge beam positioning block 12. The accompanying frame body is made up of two longitudinal beams 3 and four beams 4,5,6,7. The positioning frame body of the TC car and the positioning frame body of the MC car are each divided into two parts, and a channel is formed by breaking from it. The distance from the beam 7 on the accompanying frame body to the left end positioning reference is 19700 mm. Here is the channel of the positioning frame body 2 of the MC car. , the crossbeam 4 on the accompanying frame body is 20180 millimeters away from the right end positioning datum, here is the channel place of the TC car positioning frame body 1, and the accompanying frame body passes through the channel and is set. The positioning frame body of TC ca...

Abstract

A roof steel structure pairing device in a railway vehicle comprises a TC vehicle location frame body, an MC vehicle location frame body, an accompanying frame body, support legs, a support, bending beam location bodies and press blocks. The device is characterized in that the TC vehicle location frame body and the MC vehicle location frame body are both divided into two halves and disconnected from the middle to form a channel, and the accompanying frame body penetrates the channels. An original roof bending beam location device is divided into two halves and disconnected from the middle to form a channel, the surplus 10-meter-long site is utilized to remanufacture a set of roof bending beam location device which is also divided into two halves, a beam on the 20-meter-long accompanying frame penetrate the channels to achieve the effect that the 30-meter-long site can be provided with two sets of 20-meter-long tools, namely, a TC vehicle bending beam location device and the MC vehicle bending beam tool location device, the two sets are installed onsite, and the problem of frequent adjusting of two vehicle types is solved. The two sets of independent tool location bending beams are adopted, the tool stability is ensured, labor intensity of workers is reduced, factory utilization rate is improved, and production efficiency is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of rail vehicle manufacture, and in particular relates to a vehicle roof assembly device. Background technique [0002] In the production of the mid-roof steel structure of double-decker railway cars in Australia, the existing mid-roof steel structure assembly device has a 20-meter-long conformal frame, and the 20-meter-long mid-roof steel structure is on this conformal frame Group pair. Since the existing factory building only has a 30-meter site, only one set of 20-meter tooling can be installed. Meanwhile, TC cars and MC cars are two different types of vehicles. Production TC cars and MC cars are synthesized on this set of tooling, and only by adjusting the positioning of the tooling can the conversion of vehicle types be realized. Due to the increase in production capacity, the situation of changing models is relatively frequent. It is adjusted once every two or three days, and it takes 36 hours to ad...
