Linkage type multi-axis numerical control gantry machining center

The invention relates to a numerical control gantry machining center technology, in particular to a linkage type multi-axis numerical control gantry machining center which is used for solving the problems that chippings generated during machining of a machining center cannot be comprehensively collected and the chippings are prone to being damaged during follow-up collection treatment, and comprises a base, a workbench, a reciprocating lead screw, a cleaning cavity, a chipping passing groove and a cleaning plate. An air guide pipe reciprocates along with the cleaning plate under the action of the reciprocating lead screw to clean scrap iron on the workbench, so that the numerical control gantry machining center can clean the residual scrap iron on the workbench through the air guide pipe in the machining process, steering is carried out through the interaction between a splicing structure formed by splicing multiple sliding frames and a steering plate, the scrap iron at all positions on the workbench is clean
