Fixing device used for simultaneously welding multiple locomotive drain pipes

Abstract

The invention discloses a fixing device used for simultaneously welding multiple locomotive drain pipes. The fixing device used for simultaneously welding the multiple locomotive drain pipes comprisesa base plate and a U-shaped fixing plate. Fastening holes are formed in two vertical sections of the fixing plate. Protrusions are arranged at the two ends of the base plate correspondingly. Bolts movably penetrate through the protrusions and then are matched with the fastening holes. The side wall of the base plate and the side wall of the fixing plate are each provided with a plurality of semicircular grooves with the radii becoming smaller gradually, and the every two semicircular grooves with the same radius are combined to form a complete clamping ring. The diameters of the multiple circular clamping rings are decreased gradually in the axis direction of the base plate so that pipes which have different sizes and distributed stage by stage can be clamped, and the clamped pipes can beconveniently and rapidly mounted or dismounted by workers.

Description

technical field [0001] The invention relates to the field of locomotive parts processing, in particular to a fixing device for simultaneous welding of multiple locomotive drainage pipes. Background technique [0002] At present, when processing locomotive drainage pipelines, it is necessary to weld many different types of replacement parts, and the pipe clamps used in them are generally non-standard parts. Each model needs to be equipped with different pipe clamps according to the type and size of the pipe fittings. , This will cause a wide variety of pipe clamps, and different pipe clamps need to be processed according to the model, which not only makes the processing cost high, but also has a long processing cycle, which is not conducive to mass production. How to develop a pipe clamp that is applicable to different models and can be used for multiple pipe fittings of different sizes at the same time is a technical problem to be solved urgently by those skilled in the art....
