Abstract

The invention discloses a master welding fixture for aluminum alloy vehicle bodies, which comprises a bottom platform and left and right platforms arranged on the bottom platform, wherein horizontal sliding track components are arranged on the bottom platform, the left platform and the right platform are connected with the bottom platform in a sliding manner through the sliding track components, the left platform and the right platform are connected with sliding cylinders respectively, and the sliding cylinders drive the left platform and the right platform to slide and displace in the horizontal direction; a plurality of positioning mechanisms are arranged on the bottom platform, the left platform and the right platform respectively; each positioning mechanism comprises a basal plate, a positioning block and a telescopic positioning pin; adjusting gaps are reserved between the positioning blocks and the basal plates; and a plurality of second-order power cylinders and clamping cylinders are symmetrically arranged on the left and the right platforms. The master welding fixture is designed according to the features of structures and materials of the aluminum alloy vehicle bodies.

Description

technical field [0001] The invention relates to the field of tooling fixtures, in particular to a general welding fixture for an aluminum alloy vehicle body. Background technique [0002] In the traditional general welding fixture, the platform for left and right movement is generally realized by a simple mechanism, such as a sliding mechanism using a pulley, etc., the movement is unstable and the positioning accuracy is poor. The positioning block of the fixture is generally machined in place at one time, and the adjustment margin after the installation of each positioning component is extremely small. If the processing error of the positioning component itself is large, it cannot be adjusted to the theoretical position after assembly. Traditional sheet metal body welding fixtures also use the combination of positioning pins and positioning surfaces when positioning the workpiece, but most of them use fixed positioning pins. After welding, the workpiece will have a certai...
