Abstract

The utility model discloses a quick response type numerical control lathe which comprises a base, wherein a lathe bed is installed on the base, an X-direction sliding plate and a Z-direction sliding plate are arranged on the lathe bed, a headstock is arranged on the X-direction sliding plate, the Z-direction sliding plate is provided with a tool rest, and the Z-direction sliding plate is connected with a linear motor arranged on the lathe bed in a transmission mode. The Z-direction sliding plate is driven by the linear motor in non-clearance mode. When machining ball nuts, the headstock is stationary while the tool rest moves quickly as required. Therefore, the motion accuracy of the tool rest directly affects the machining accuracy of a workpiece, and direct linear motor driving can increase accuracy and improve quick response performance. In addition, as the X-direction sliding plate and the Z-direction sliding plate are designed separately and are respectively provided with the headstock and the tool rest, the movements of the Z-direction sliding plate and the X-direction sliding plate do not affect each other or cause error or superposition of vibration.

Description

The rapid response type numerically controlled lathe

Technical field

The utility model relates to lathe, particularly relates to numerically controlled lathe.

Background technology

Numerically controlled lathe is called the CNC lathe again, and promptly the computer numerical control (CNC) lathe is present use amount maximum, a kind of Digit Control Machine Tool that coverage rate is the widest.Digit Control Machine Tool is that multinomial technology such as mechanical, electric, the hydraulic pressure of collection, pneumatic, microelectronics and information are the electromechanical integrated product of one, be the machine-tool that has advantages such as high accuracy, high efficiency, high automation and high flexibilityization in the mechanical production devices, have technology capability energy widely.At present, the X of numerically controlled lathe is to all controlling by servomotor to the feed motion of slide plate with Z.Yet when the processing ball nut, owing to need the knife rest fast moving, its precision that moves directly has influence on the machining accuracy of ball nut, and is difficult to reach requirement with slide plate its kinematic accuracy under high-speed mobile of servomotor control.

The utility model content

For addressing the above problem, the utility model provides a kind of slide plate to have the numerically controlled lathe of high mobile accuracy when high-speed mobile.

The technical scheme that its technical problem that solves the utility model adopts is:

The rapid response type numerically controlled lathe comprises base, on the described base lathe bed is installed, be equipped with on the described lathe bed X to slide plate and Z to slide plate, described X is equipped with main spindle box on slide plate, described Z is equipped with knife rest on slide plate, described Z to slide plate be installed in that linear electric motors are in transmission connection on the lathe bed.

As improvement of the technical scheme, described Z is installed on the lathe bed to hydrostatic slideway by Z to slide plate, and described X is installed on the lathe bed to the composite guideway of hydrostatic slideway and line slideway composition by X to slide plate.

The beneficial effects of the utility model: the Z of of the present utility model lathe adopts linear electric motors not have the gap to slide plate and drives, because during the processing ball nut, main spindle box does not move, and knife rest needs fast moving, therefore the precision that moves of knife rest directly influences the machining accuracy of workpiece, therefore adopt linear electric motors directly to drive, can improve precision to greatest extent and improve fast-response.In addition, because X is separately designed to slide plate to slide plate and Z, and respectively at last installation main spindle box and knife rest, motion separately can not influence each other, and can not cause the stack of error and vibrations.

Description of drawings

The utility model is described in further detail below in conjunction with accompanying drawing:

Fig. 1 is the utility model embodiment perspective view;

Fig. 2 is the utility model embodiment Facad structure schematic diagram.

The specific embodiment

With reference to Fig. 1, Fig. 2, rapid response type numerically controlled lathe of the present utility model, comprise base 1, on the described base 1 lathe bed 2 is installed, be equipped with on the described lathe bed 2 X to slide plate 3 and Z to slide plate 4, described X is equipped with main spindle box 5 on slide plate 3, described Z is equipped with knife rest 6 on slide plate 4, described Z to slide plate 4 be installed in that linear electric motors 9 are in transmission connection on the lathe bed 2.The Z of of the present utility model lathe adopts linear electric motors 9 directly not have the gap to slide plate 4 and drives, because during the processing ball nut, main spindle box 5 does not move, and knife rest 6 needs fast moving, therefore the precision that moves of knife rest 6 directly influences the machining accuracy of workpiece, therefore adopt linear electric motors directly to drive, can improve precision to greatest extent and improve fast-response.In addition, because X is separately designed to slide plate 4 to slide plate 3 and Z, and main spindle box 5 and knife rest 6 are installed respectively thereon, motion separately can not influence each other, and can not cause the stack of error and vibrations.

As preferred implementation, described Z is installed on the lathe bed 2 to hydrostatic slideway 7 by Z to slide plate 4, and described X is installed on the lathe bed 2 to the composite guideway of hydrostatic slideway 8 and line slideway 10 compositions by X to slide plate 3.Like this, combine the two-fold advantage of hydrostatic slideway and line slideway, utilize the guidance quality of the damping performance and the line slideway of hydrostatic slideway, thereby make product of the present utility model have high manufacturing accuracy.

Certainly, the invention is not limited to above-mentioned embodiment, those of ordinary skill in the art also can make equivalent variations or replacement under the prerequisite of the utility model spirit, modification that these are equal to or replacement all are included in the application's claim institute restricted portion.
