Abstract
The utility model relates to the technical field of machine tool manufacturing, in particular to a machine tool spindle box ram structure. The machine tool spindle box ram structure comprises a slide carriage and a spindle box ram movably disposed on the slide carriage. The machine tool spindle box ram structure is characterized in that guide rails and a support rail are arranged on the spindle box ram, the guide rails which are two linear rails are disposed on two opposing sides of the spindle box ram, a linear rail slider fixedly connected with the slide carriage is arranged on the linear rails and allows the spindle box ram to slide along the linear rails when the spindle box ram is driven by a driving device, and the support rail is disposed on the contact surface, with no linear rails and opposite to the slide carriage. During operation of the machine tool spindle box ram structure, the spindle box ram is driven by the driving device to slide along the linear rails, a square rail supports the slide carriage when the spindle box ram runs, dynamic stiffness and static stiffness of the spindle box ram in operation are increased, and a clearance between the spindle box ram and the slide carriage can be adjusted through a clearance adjusting mechanism.
Description
Technical field

Background technology
Digit Control Machine Tool is widely used in part processing, existing traditional its main spindle box ram of lathe slides on slide by hard rail, main spindle box ram and slide need leave the gap at translational surface and just can move, and hard rail coefficient of friction is large, is unfavorable for the processing precise part; Comparatively advanced main spindle box ram slides on slide by the line rail, but adopts the line rail can not bear large disturbing moment, and therefore the sound poor rigidity cuts that ability is weak, the scope of application is restricted.
The utility model content
Sound rigidity when guaranteeing that the main spindle box ram moves, the utility model provides a kind of lathe headstock ram structure, comprise slide, be movably set in the main spindle box ram on slide, it is characterized in that: described main spindle box ram is provided with guided way and supporting rail, described guided way is two line rails, article two, the line rail is arranged in respectively on two opposites of main spindle box ram, the line rail is provided with the line rail slide block that is fixedly connected with slide, and main spindle box ram rail along the line when being activated the device driving is slided; Described supporting rail is arranged in not to be had on line rail and the contact-making surface relative with slide.
Further, supporting rail is two square rails, and two square rails are arranged in respectively the left and right two ends of contact-making surface.
Further, the main spindle box ram is provided with nut seat, and described drive unit comprises the screw mandrel that passes nut seat and the servomotor that drives the screw mandrel rotation.
Further, nut seat is arranged between two square rails.
Further, slide is provided with for the gap adjusting mechanism of adjusting slide and supporting rail distance.
Further, gap adjusting mechanism comprises the adjustment panel, adjusts and insert and adjust screw, and described adjustment is inserted and is fixedly installed on slide, and the adjustment panel is inserted with adjustment by the adjustment screw and is connected.
By above-mentioned to description of the present utility model as can be known, compared with prior art, the utlity model has following beneficial effect:
This kind lathe headstock ram structure is in running, main spindle box ram rail along the line when being activated the device driving slides, side's rail is at the support slide in service of main spindle box ram, improve the sound rigidity in main spindle box ram running, and can adjust gap length between main spindle box ram and slide by gap adjusting mechanism.
