Problems solved by technology

In the case of parallel production of multiple car models and the original tooling cannot be used in common, frequent replacement of frame welding jigs is required. Moreover, with the increase of product models, the number of frame welding jigs gradually increases, which requires a lot of tooling production costs. In addition , the original frame welding fixture is in poor condition and needs frequent maintenance
These have brought great challenges to production management, tooling management, cost control, etc.

Abstract

The invention relates to the technical field of bogie welding, in particular to a framework two-axis welding positioning device. The device comprises a bottom plate, sliding tables, supporting beams, cross beam steel pipe pressers and cross beam steel pipe height positioners, wherein the framework two-axis welding positioning device is arranged on a corresponding rotating table through the bottom plate; the bottom plate is provided with a guide rail; two sliding tables are arranged on the guide rail of the bottom plate; a supporting beam is arranged on each sliding table; the two supporting beams are parallel to each other; each supporting beam is provided with a cross beam steel pipe presser and a cross beam steel pipe height positioner; the cross beam steel pipe pressers and the cross beam steel pipe height positioners are arranged at the two ends of the supporting beams respectively and the cross beam steel pipe presser on one supporting beam corresponds to the cross beam steel pipe height positioner of the other supporting beam; the guide rail is arranged at the ends, provided with the cross beam steel pipe pressers, of the supporting beams; the cross beam steel pipe pressers are arranged on the guide rail of the supporting beams. The device realizes tool universalization, so the cost can be reduced and the efficiency can be improved by technological equipment.

Description

technical field [0001] The invention relates to the technical field of bogie welding, in particular to a two-axis welding positioning device for a bogie welding frame. Background technique [0002] At present, the number of frame two-axis rotary tires in the existing automatic bogie welding production line is limited. Therefore, under the premise of a certain EMU production capacity, the frame two-axis rotary tires outside the production line will undertake the frame welding tasks of various vehicle models. In the case of parallel production of multiple car models and the original tooling cannot be used universally, frequent replacement of frame welding jigs is required. Moreover, with the increase of product models, the number of frame welding jigs is gradually increasing, which requires a lot of tooling production costs. In addition , The original frame welding jig is in poor condition and needs frequent maintenance. These have brought great challenges to production manag...
