Abstract

The invention discloses a clamp used for welding a beam of a bogie of a railway vehicle. The clamp comprises a support base body, a rotating device and a clamping device, wherein the support base body is provided with a base, a rib plate, a support base and a first fixed base; the rotating device is provided with a turbine speed reducer, a connecting rotating shaft, a first sealing cover, a bearing, a support sleeve, a second sealing cover, a locking sheet and a hexagon socket head cap screw; the clamping device is provided with a second fixed base, a locking bolt, a connecting base, a connecting pin, an upper clamping base and a lower clamping base. The clamp used for welding the beam of the bogie of the railway vehicle is simple in structure, convenient and practical, can be applicable for welding the beam of the bogie of any railway vehicle, is convenient to overturn and uniform in speed, can guarantee clamping safety, enables the welding to be more convenient, and can guarantee smoothness and stability of the mechanism under the action of a fixed pin particularly when a front side and a reverse side are welded.

Description

technical field [0001] The invention relates to a welding fixture, in particular to a fixture used for welding rail vehicle bogie beams. Background technique [0002] In today's rail vehicle lower body welding production process, due to the large volume of the bogie, it is not easy to turn over, which brings great difficulties to welding, resulting in uneven welds, which will lead to welding defects of the bogie, so a design that can A soldering jig that flips easily is essential. Contents of the invention [0003] The object of the present invention is to provide a clamp for rail vehicle bogie beam welding to address the deficiencies in the prior art. [0004] In order to achieve the above object, the method adopted in the present invention is: a fixture for rail vehicle bogie beam welding, comprising a support base, a rotating device, and a clamping device; the support base is provided with a base, ribs, The support seat and the first fixed seat, the base is set...
