Digit Control Machine Tool
The utility model relates to a kind of process equipment, relates in particular to a kind of Digit Control Machine Tool of cross beam type.
Be accompanied by the development of national economic development, a large amount of precision parts need suitable lathe to produce, so high precision, high stability lathe have become the trend of technical development.In existing lathe, workbench is often taked to be arranged on guide rail, thereby processes with the cooperation main spindle box along the guide rail rectilinear motion.Yet the workbench in moving has reduced the stability of extra bed undoubtedly, has lowered the precision of processing.
The utility model content
Therefore, the purpose of this utility model is to provide a kind of high stability, high-precision Digit Control Machine Tool.
A kind of Digit Control Machine Tool, this Digit Control Machine Tool comprise a base, be fixed on workbench on base, be fixed on the relative both sides of workbench the two wires rail, be arranged on crossbeam on this two wires rail, be arranged on the slide on this crossbeam and be arranged on head on this slide; This head this slide relatively moves up and down along Z axis, and described slide drives head and can move horizontally along Y-axis on crossbeam, and described crossbeam drives on slide and the online rail of head and moves horizontally along X-axis.
Further, described each line rail comprises one first screw mandrel and is positioned at the guide rail of the relative both sides of this first screw mandrel.
Further, two ends, described crossbeam bottom are respectively equipped with a guide holder, and each guide holder coordinates with described the first screw mandrel and guide rail.
Further, the leading flank of described this crossbeam is provided with along the second screw mandrel of Y direction extension and is positioned at this second screw mandrel guide rail of both sides up and down, and described slide coordinates with the second screw mandrel and the guide rail of this crossbeam.
Further, described base is provided with a vertical tool magazine, this tool magazine be positioned at described workbench along the outside, the rear end of X-axis, described head be positioned at this tool magazine directly over be to realize automatic tool changer.
Compared with prior art, the utility model Digit Control Machine Tool is fixed on workbench on base, control described head moving relative to three directions of X, Y, Z axis of workbench by servomotor, thereby implement three-dimensional movement, improve the stability of workbench, made the machining accuracy of head higher.
Description of drawings
Fig. 1 is the structural representation of Digit Control Machine Tool of the present utility model.
The specific embodiment
For the technical solution of the utility model can more clearly be showed, the utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, be the Digit Control Machine Tool of the utility model one preferred embodiment.This Digit Control Machine Tool comprises a base 10, be fixed on workbench 20 on base 10, be fixed on workbench 20 relative both sides two wires rail 60, be arranged on crossbeam 30 on this two wires rail 60, be arranged on the slide 40 on this crossbeam 30 and be arranged on head 50 on this slide 40.This head 50 this slide 40 relatively moves up and down along Z axis, and described slide 40 drives head 50 and can move horizontally along Y-axis on crossbeam 30, and described crossbeam 30 drives on slide 40 and the online rail 60 of head 50 and moves horizontally along X-axis.
Also be provided with a vertical tool magazine 70 on described base 10.This tool magazine 70 be positioned at described workbench 20 along the outside, the rear end of X-axis, when crossbeam 30 moves back along X-axis the rear end of discharging line rail 60, head 50 be positioned at this tool magazine 70 directly over realize automatic tool changer.
Each line rail 60 comprises one first screw mandrel 61 and is positioned at the guide rail 62 of this first screw mandrel 61 relative both sides, and this first screw mandrel 61 is arranged in parallel with guide rail 62.This first screw mandrel 61 drives the nut (figure does not look) of this crossbeam 30 by servomotor (figure does not look), drive this crossbeam 30 movement on X-direction to control.
Described crossbeam 30 two ends, bottom are respectively equipped with a guide holder 32 to coordinate with described the first screw mandrel 61 and guide rail 62.The leading flank of this crossbeam 30 is provided with the second screw mandrel 31 that extends along Y direction and the guide rail 33 that is positioned at this second screw mandrel both sides Shang Xia 31.This second screw mandrel 31 drives the nut (figure does not look) of described slide 40 by servomotor (figure does not look), drive this slide 40 movement on Y direction to control.Described head 50 by servomotor (figure do not look) relatively this slide 40 move up and down in Z-direction.
During work, described workbench 20 is fixed on base 10, controls described head 50 relative to the moving of three directions of X, Y, Z axis of workbench 20 by servomotor, thereby implements three-dimensional movement, improve the stability of workbench 20, made the machining accuracy of head 50 higher.In addition, self arrangement tool magazine 70 facilitates installation and debugging, and automatic tool changer improves working (machining) efficiency.
The above embodiment has only expressed a kind of embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.Should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
