Mobile docking frame for large parts with multiple lugs

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 car with multiple lugs and large parts, which belongs to the technical field of assembly. Background technique [0002] There are 2 sets of butt joints for the large parts of the multi-ear piece, and the distribution length of the joints is 2100mm. The upper group has a total of 23 pairs of intersections, and the lower group has a total of 14 pairs of intersections. The ears are the reference for the fit. There is a 1.5mm gap between the rest of the upper prongs, and the gap between the lower prongs is 0.5mm, and it is not allowed to be less than 0.3mm. In the past, the number of docking points for components is up to 6 pairs of fork lugs, and it is an axis, of which one is the docking reference, and the gap between the remaining fork lugs can reach 3mm. For this reason, the conventional docking tool uses a fixed bracket, and the suspension is manually moved during docking. After the components are aligned wi...

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.
