Background

There are a large number of large and large thin parts in rail vehicles, such as side walls, floors, roofs, etc., with widths of up to 3 meters and lengths of up to 20 meters, but with thinner thicknesses. According to functional requirements, a plurality of openings exist in the part, such as windows and doorways of side walls, air-conditioning wells and electric appliance wells of roofs, and the part needs to be connected with other parts or other small parts are installed on the part, so that a large amount of cutting processing is needed on the large and large thin parts.

The following difficulties exist in processing such large and large thin parts:

1. the ratio of the area to the thickness of the long and large thin part is large, and most of the long and large thin parts have the shape radian of a railway vehicle, so that the long and large thin part has risks of distortion or local deformation and the like in the clamping process and influences on the whole processing quality;

2. the surface of the part is too large, the pressing part is too far away from the machining part, so that the pressing point cannot be close to the machining part, the pressing force of the machining part is insufficient, strong vibration is easily generated during machining, on one hand, the machining quality is influenced, the service life of a machine tool is reduced, on the other hand, high noise is generated, and the damage to a human body is caused.

In the prior art, cutting processing of a long and large thin part of a railway vehicle mainly adopts two processing means, wherein the first means is to clamp the part by matching a simple cushion block, a pressure plate and a screw; and the second method is to integrally clamp the long and large thin part by using a special tool.

However, after a long time of practice, the processing mode in the prior art has many defects: firstly, the large and large thin parts are mostly in arc curved surface structures, the simple cushion blocks and the pressing plate are actually in line contact for clamping, the clamping area is small, and the workpiece is easy to deform due to overlarge stress; secondly, some processing parts are positioned in the middle of the part and are far away from the peripheral compaction area; if the compaction area is arranged at the periphery of the part, the compaction force requirement of a machining part cannot be met only by the strength of the part due to too far distance, so that the clamping force of the part to be machined is insufficient, and the vibration during cutting is aggravated; if the periphery of the processing area is compressed by the lengthened pressing arm, the pressing device is huge in appearance, complex in structure and inconvenient to operate, the material piece switching time is prolonged, and the tooling cost is increased; thirdly, due to the fact that the long and large parts to be processed mostly have special structures such as cavities, noise is easy to generate, and the tool in the prior art cannot absorb or isolate the noise, so that the working environment is affected.

Finally, based on the above technical problems, a need is felt by those skilled in the art to develop a novel flexible crawler-type shock-absorbing pressing system suitable for cutting and machining long and large thin parts in rail vehicles.

The system adopts a modular design, has a simple structure, is convenient to manufacture and has low cost.

The system does not need to be provided with an overlong pressing arm, the size of the tool is effectively reduced, the pressing force can be enhanced by locally increasing the pressing trolley 3, the processing part which cannot be avoided in the range of the pressing system can be avoided by locally reducing the pressing trolley 3, and the use mode is flexible.

The pressing force of the invention is provided for the periphery of the workpiece 10 to be processed by applying pressure downwards through the main shaft 11 by the locking mechanism in the longitudinal beam 103, and sufficient pressing force is provided for the part to be processed, so that the phenomenon of insufficient pressing force is effectively avoided, and unnecessary pressing devices on the periphery are reduced. The EPDM rubber track can effectively absorb redundant vibration, reduce the damage of the vibration to a workpiece, a cutter and a machine tool, greatly reduce noise and reduce the damage to the environment.

While certain exemplary embodiments of the present invention have been described above by way of illustration only, it will be apparent to those of ordinary skill in the art that the described embodiments may be modified in various different ways without departing from the spirit and scope of the invention. Accordingly, the drawings and description are illustrative in nature and should not be construed as limiting the scope of the invention.
