Flexible reconstruction automobile welding and assembling clamp

Abstract

The present invention relates to a flexible reconfigurable automobile welding clamp comprising a base desk, a clamping mechanism and an independent main positioning mechanism. The present invention is characterized in that the clamping mechanism comprises an upright post, an inner sleeve, an outer sleeve, a L-shaped upright post, a flat plate connecting piece, a compacting block and a compacting connecting bar; the inner sleeve is fixed on the upright post; the outer sleeve is sheathed outside of the inner sleeve and the inner sleeve and the outer sleeve is adjustably connected with each other; the L-shaped upright post is fixed on the outer sleeve and is fixedly connected with the flat plate connecting piece on the side surface; the front end of the flat plate connecting piece is fixedly connected with the compacting block by the compacting connecting bar; the independent main positioning mechanism comprises a positioning piece, a middle transition piece, a L-shaped block, a flat plate provided with holes, a L-shaped connecting block and a flat plate; the flat plate provided with holes is fixedly connected on the flat plate by the L-shaped connecting block; the L-shaped block is connected with the flat plate provided with holes and is connected with the middle transition piece. The clamp of the present invention has a high flexibility, is adapted to a plurality of different workpieces, can be reconfigured rapidly, thereby the cost is reduced and the production efficiency is improved.

Description

technical field [0001] The invention relates to a welding jig for body stamping parts in automobile production, in particular to a fixture platform for a welding system for automobile body stamping parts. Background technique [0002] The existing welding fixtures for automobile stamping parts are usually designed for one station. When the workpiece on the station changes greatly, a set of fixtures must be redesigned, which greatly increases the production cost and reduces the production cost. efficiency. [0003] The current welding fixture for automobile stamping parts mainly consists of the following parts: abutment, column, positioning element, clamping element, connecting plate connecting the positioning clamping element and column, gasket, cylinder, pneumatic control element, etc. The connection between the column and the abutment mainly depends on the screw connection after drilling, and it cannot be changed after the drilling connection. The whole device is clamped...
