Description
Technical field
The present invention relates to a kind of action driver of Digit Control Machine Tool.
Background technology
Digit Control Machine Tool is the abbreviation of numerically-controlled machine tool, is a kind of automated machine tool that program control system is housed.This control system can logically process has control coding or other symbolic instruction regulated procedures, and by its decoding, by the numeral of encode, inputs numerical control device by information carrier.Send various control signal through calculation process by numerical control device, control the action of lathe, shape and size by drawing, automatically process part.Digit Control Machine Tool solves the part processing problems of complexity, precision, small lot, multi items preferably, is a kind of flexibility, dynamical automated machine tool, represents the developing direction of modern machine control technology, is a kind of typical electromechanical integrated product.
In Digit Control Machine Tool, usually can use linear reciprocation drive unit, to drive operand Linear-moving, but the helical pitch of common reciprocating drive unit is generally fixed value, can not adjust according to different machining states.
Summary of the invention
The invention is intended to provide a kind of panoramic table reciprocating movement driving device, to realize the adjustable Linear Driving of helical pitch.
Panoramic table reciprocating movement driving device in this programme, include housing, housing is connected with gyroaxis, gyroaxis rotates and is connected with revolving bed, revolving bed rotates and is connected with drive screw, drive screw and gyroaxis are vertical in the axial direction, drive screw is by the drive unit driven rotary be located on revolving bed, on drive screw, thread connection has nut, nut is connected with the pole vertical with drive screw, housing has been fixedly connected guide post, force-application block is slidably connected by the pilot hole on it and guide post, force-application block is provided with guide rod, guide rod has been slidably connected slide block, slide block connects with the rotation of described pole.
Drive unit outputting power in this device on revolving bed, and drive screw rod to rotate, the rotation of screw rod and drive nut action, because nut connects with the slide block that cannot rotate, so nut moves in the axis of screw rod, simultaneously nut move axially through pole, slide block drives force-application block to move up in the side of guide post, force-application block can the thrust of output reciprocating motion to external world.When needing the helical pitch changing force-application block, rotate the revolving bed on gyroaxis, can change the length of screw rod on guide post direction, the rectilinear motion of nut still can pass to force-application block by said structure, and the helical pitch of force-application block have also been obtained change simultaneously.This device may be used for various mechanisms Digit Control Machine Tool needing adjust rectilinear movement helical pitch.
Further, described drive unit is stepper motor.Its duty is adjusted in mode more easily.
Further, housing is provided with the revolution stepper motor driving revolving bed to rotate.
Further, stepper motor is connected with rotary encoder, to realize high-precision position control.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention.
Detailed description of the invention
Below by detailed description of the invention, the present invention is further detailed explanation:
Reference numeral in Figure of description comprises: gyroaxis 1, revolving bed 2, drive screw 3, nut 4, pole 5, slide block 6, guide rod 7, force-application block 8, guide post 9.
Embodiment is substantially as shown in Figure 1: be the internal structure of better exhibiting device, housing is not shown in figures.Housing is provided with revolution stepper motor, its output shaft and gyroaxis driving coupling straight up, gyroaxis is connected with revolving bed.Namely the rotation of revolution stepper motor drives revolving bed to rotate in the horizontal direction.
The otic placode that on revolving bed, two ends are erect is rotated by bearing and is connected with drive screw, drive screw and gyroaxis are vertical in the axial direction, drive screw is by the stepper motor (not shown) driven rotary be located on revolving bed, and stepper motor is provided with rotary encoder.
On drive screw, thread connection has square nut, and on nut, retaining thread is connected with the pole vertical with drive screw.Drive unit outputting power in this device on revolving bed, and drive screw rod to rotate, the rotation of screw rod and drive nut action,
Two guide posts of horizontal direction that housing is fixedly connected, square force-application block is slidably connected by the pilot hole of two on it and guide post, the side of force-application block is provided with guide rod, guide rod is positioned at same level with guide post and mutually vertical, guide rod is slidably connected square slide block, slide block rotates with the upper end of described pole and connects.
Because nut connects with the slide block that cannot rotate, so nut moves in the axis of screw rod, simultaneously nut move axially through pole, slide block drives force-application block to move up in the side of guide post, force-application block can the thrust of output reciprocating motion to external world.When needing the helical pitch changing force-application block, rotate the revolving bed on gyroaxis, can change the length of screw rod on guide post direction, the rectilinear motion of nut still can pass to force-application block by said structure, and the helical pitch of force-application block have also been obtained change simultaneously.
Above-described is only embodiments of the invention, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the prerequisite not departing from structure of the present invention, some distortion and improvement can also be made; these also should be considered as protection scope of the present invention, and these all can not affect effect of the invention process and practical applicability.The protection domain that this application claims should be as the criterion with the content of its claim, and the detailed description of the invention in description etc. record the content that may be used for explaining claim.
