Car floor welding tool of rail vehicle

Abstract

The invention discloses a car floor welding tool of a rail vehicle. The car floor welding tool of the rail vehicle comprises a platform support, straight guide rails, a driving compression support, a driven compression support, floor support blocks, driving transverse compression heads, driven transverse compression heads, rotation vertical hydraulic pressure arms and a hydraulic pressure driving mechanism. Through the car floor welding tool of the rail vehicle, actions of the driving transverse compression heads for compressing floors transversely and the rotation vertical hydraulic pressure arms for compressing the floors vertically are controlled by a hydraulic pressure system; compression and loosening are finished automatically; the time for clamping is short, so that the working efficiency can be greatly improved; transverse compression forces applied by the driving transverse compression heads to the floors are the same, and the vertical compression forces applied by the rotation vertical hydraulic pressure arms to the floors are also the same, so that the stress deformation of the floors can be alleviated, and the welding quality can be improved; the positions of the driving compression support, the driven compression support and the floor support blocks can be adjusted, and thus the tool is capable of clamping car floors with different specifications and good in adaptability; the tool cost can be reduced.

Description

technical field [0001] The invention relates to the field of welding equipment, in particular to a welding tool. Background technique [0002] Most of the existing compacting devices for rail vehicle floor welding tooling use manual screw compacting devices, which have the following main disadvantages: [0003] 1. Manually rotate the lead screw to compress or loosen the weldment, and the work efficiency is low; [0004] 2. When pressing manually, it is impossible to ensure that the pressure of each pressing point is the same, which will easily cause deformation of the weldment and affect the welding quality. [0005] Moreover, the weldment supporting pads of the existing rail vehicle floor welding tooling cannot be moved, so that the same tooling can only weld a single product, and the investment in the tooling is large, and the welding cost is high. Contents of the invention [0006] In view of this, the purpose of the present invention is to provide a rail vehicle floo...
