Problems solved by technology

Due to the different length, height, wheelbase and other dimensions of various models, a large number of frame assembly tailor welding fixtures are designed and produced for different frames. The structure of the fixture is complex and the welding workload is large.
[0003] At present, there are many types of passenger cars. For some companies with the characteristics of small batches and multiple types of buses, this method will greatly increase the input cost, and it will occupy a large area of ​​the site, and the operation is more complicated. Severe deformation, large workload for each adjustment, resulting in low production efficiency, lower quality of frame assembly and other adverse consequences

Abstract

The invention relates to a general welding jig applied to manufacturing a fully-integral chassis. The general welding jig comprises a fixed work table, six movable installing-welding bases and twelve positioning units. The six movable installing-welding bases are arranged on the fixed work table in a scattered mode, and the twelve positioning units are arranged on the six movable installing-welding bases in pairs. According to shapes and sizes of workpieces, the movable installing-welding bases are moved and matched with the corresponding positioning units, and the workpieces are fixed onto the fixed work table to be welded. Compared with the prior art, the general welding jig has the advantages of being wide in application range, safe, reliable, convenient to operate and the like.

Description

technical field [0001] The invention relates to a jig, in particular to a universal welding jig suitable for the manufacture of a fully loaded chassis. Background technique [0002] The current Ministry of Industry and Information Technology (2011) No. 632 document requires that starting from September 1, the frames of tourist vehicles over 11 meters (including 11 meters) should all adopt full load-bearing structures. The frames are welded by special-shaped steel pipes and section steels of various specifications. Grid space structure. Due to the different length, height, wheelbase and other dimensions of various models, a large number of frame assembly tailor welding fixtures are designed and produced for different frames. The fixture structure is complex and the welding workload is heavy. [0003] At present, there are many types of passenger cars. For some companies with the characteristics of small batches and multiple types of buses, this method will greatly increase t...
