Multi-lug-sheet large-size component movement butt joint unwheeling

Abstract

The invention relates to a multi-lug-sheet large-size component movement butt joint unwheeling which is mainly composed of a fixed unwheeling body and an adjusting unwheeling body. The fixed unwheeling body is connected with the adjusting unwheeling body through a clamping device, brackets are arranged above the fixed unwheeling body and the adjusting unwheeling body respectively, and intersection point location devices are arranged at the two ends of each bracket respectively. The bracket of the adjusting unwheeling body is movably connected with the adjusting unwheeling body through a frame, a left moving hand wheel, a right moving hand wheel, a front moving hand wheel and a back moving hand wheel are arranged on a driving device located on the adjusting unwheeling body, and an upper adjusting hand wheel and a lower adjusting hand wheel are arranged on the bracket of the adjusting unwheeling body. The multi-lug-sheet large-size component movement butt joint unwheeling can achieve adjustment in six freedom degree directions, so that accurate location, adjustment, overhauling, backfit and butt joint can be achieved when the butt joint is carried out on intersection points of multi-lug-sheet large-size components.

Description

technical field [0001] The invention relates to a mobile docking frame vehicle for large parts with multiple lugs, which belongs to the technical field of assembly. Background technique [0002] There are 2 sets of butt joint intersections for the multi-lug large parts, and the distribution length of the intersections is 2100mm. Among them, the upper set has 23 pairs of intersections, and the lower set has 14 pairs of intersections. The lugs are used as the matching reference, and there is a gap of 1.5mm between the rest of the upper fork lugs, and the gap between the lower fork lugs is 0.5mm, and it is not allowed to be less than 0.3mm. In the past, the number of butt joint intersections of components was at most 6 pairs of fork lugs, and it was an axis, one of which was the butt joint datum, and the clearance of the rest of the fork lugs could reach 3mm. For this reason, the conventional butt joint tooling adopts a fixed bracket, which is manually moved and suspended when ...

Problems solved by technology

However, most of the above-mentioned multi-lugs have 37 pairs of butt joint intersection points, and there are three axes in total. The gap between some fork lugs is only 0.5mm. Considering parts manufacturing errors, assembly errors, etc., interference between the fork lugs is very easy to occur during docking. As a result, it cannot be docked. For this reason, most of the docking differences of multi-lugs cannot be realized by the conventional fixed bracket and the docking method of manually aligning the reference lugs.
