The present invention meets positioning principle and the mode of fixture, i.e. six point location rules, and use the hand-operated clamping mode of modern rapidly and efficiently rate, 6 degree of freedom making the workpiece movement along tri-axis of OX, OY, OZ and the rotation around three axis are all limited, making workpiece decide completely in the position in space, welding equipment quality and adnexa assembling for follow-up vehicle frame provide and reliably ensure.
The present invention is a kind of typical alphabetical formula weld jig, and each movable assembly welding base joins location-plate of burn-oning, and stationary work-table is joined the lower location-plate of weldering, uses alignment pin to be fixed on the table by activity assembly welding base.Only need to realize the conversion of various vehicle by 6 movable assembly welding bases and the replacing positioning unit of sliding.
Compared with prior art, the invention have the advantages that
(1) range is wide: frock modification is quick, only need to can be achieved with the conversion of various vehicle by 6 movable assembly welding bases and the replacing positioning unit of sliding.
(2) safe and reliable: each part accurate positioning, reliable, clamping should be rapid, and vehicle frame precision is high, solves stereochemical structure planarization and makes the yielding difficult problem of crossing plane welding;
(3) easy to operate: space is spacious, operative is convenient, adapts to welding requirements, facilitates welding, and taking out workpiece from fixture should facilitate;
(4) production efficiency is high: reduce productive temp, shortens the production cycle, improves production efficiency.

Detailed description of the invention
The present invention is described in detail with specific embodiment below in conjunction with the accompanying drawings.
Embodiment 1
As shown in Fig. 1~8, a kind of being applicable to carries the General welding clamp that underframe manufactures entirely, including one by 1,6 movable assembly welding bases of 1 stationary work-table (movable assembly welding base a2, movable assembly welding base b3, movable assembly welding base c4, movable assembly welding base d5, movable assembly welding base e6, movable assembly welding base f7), 12 positioning units;6 described movable assembly welding base scattering devices are on stationary work-table 1, and 12 described positioning units are arranged on 6 movable assembly welding bases two-by-two;According to the shapes and sizes of workpiece, mobile activity bond pads base, and it is equipped with the positioning unit matched, workpiece is fixed on stationary work-table and welds.
