Description

A kind of weld jig and method
Technical field
The present invention relates to a kind of weld jig for the production of fork truck balladeur train, especially a kind of weld jig and method that automated production fork truck balladeur train is realized using controller technology, pneumatics.
Background technology
In welding technology field, according to technological principle, the vehicle weldment production of high-volume single variety is due to being that, using operation decentralization principle, positioning and clamping device are relatively simple, are easier to realize programme-control, so automaticity is higher, thus efficiency high, it is common to use automatic welding streamline, but it is big to manufacture and design line length, floor space, cost is high, widely used on batch and the production of high-volume weld car.
Also according to technological principle, small lot, the vehicle weldment production of multi items mainly use operation principle of centrality, as far as possible many parts are welded in same procedure, so positioning and clamping structure in fixture are complicated, therefore manual positioning and hand-operated clamping pattern are commonly used, so processing efficiency is relatively low.It is widely used in the fork truck production of multi items, small lot.
Statistics shows that welding structural element accounts for 40% or so in fork truck main screw lift.Many fork truck main engine plants are using weldment as the core self-made components of oneself.Three big welding structures of fork truck are door frame, vehicle frame and pontic, balladeur train is forklift fork frame, it is a critical piece for being under the jurisdiction of door frame, feature is complex structure, so its fixture is also complex, manual positioning and hand-operated clamping pattern are commonly used, thus it is less efficient, and then influence the production efficiency of vehicle.
And requirement of the existing market to forklift truck products is that just requirement is intended to the personalization of small lot multi items to product, while requiring that the delivery cycle shortens, therefore puies forward efficient problem and become increasingly conspicuous.So, automatic welding clamp of the development suitable for operation principle of centrality, it has also become solve the main path of efficiency.
