Abstract
The invention relates to a machining center, in particular to a machining center for a gantry with four linear rails and a ram. The machining center comprises a saddle (1), and is characterized in that the vertically slidable ram (2) is arranged on the saddle (1), the left and right linear rails (3) are arranged on the saddle and are positioned on two sides of the ram, the rear linear rails (4) are arranged on the saddle and are positioned at the rear of the ram, a lead screw (5) is connected to the ram and is connected with a servo motor (6), a main motor (7) is arranged on the ram and is connected with a spindle (8) by a transmission, a tool impact cylinder support (9) is arranged on the upper portion of the spindle, and a tool impact cylinder (10) is arranged on the tool impact cylinder support. The machining center has the advantage that technical problems of poor workpiece machining rigidity and precision and the like of a spindle due to the fact that a machine tool in the prior is only provided with two linear rails and a ram is poor in rigidity when sliding can be solved.
Description
[0001] technical field [0002] The invention relates to a processing center, in particular to a four-rail ram gantry processing center. Background technique [0003] The CNC gantry machining center is mainly composed of a bed, a worktable, left and right columns, a beam, a saddle, a main gearbox, a console, an electrical control box, and a drive control device. It can complete milling, drilling, reaming, boring and other multi-process processing, and is suitable for rough and fine processing of large and medium-sized parts in various industries. The Chinese patent discloses a CNC gantry car milling, boring, planing and grinding heavy-duty machine tool (publication number: CN 101502933A), which consists of a bed, a reciprocating table, a composite column, a beam, a top beam, a rotary power head, a chuck, a tailstock, The main transmission mechanism, grinding head, milling and boring head, planer tool holder, turning tool holder, electrical control system, etc.; The rack co...
