Abstract
A modified noise motion drive device for electrical discharge machining tools comprises a machine tool frame and a screw. The screw is connected with the machine tool frame through a bearing support mechanism. A motor is fixed to the machine tool frame. The control end of the motor is connected with a drive circuit board. The drive circuit board comprises a single-chip microcomputer. An output shaft of the motor is connected with a worm. A gear is coaxially fixed on the screw and meshes with the worm. The axis of the screw is perpendicular to that of the worm. One end of the worm is connected with the machine tool frame through the bearing support mechanism. A rotary encoder is disposed between the worm and the machine tool frame and connected with the drive circuit board through a signal wire. The modified noise motion drive device for electrical discharge machining tools has the advantages that displacement precision of a nose is greatly improved, the motor can drive the heavy nose with low output torque only, rotational angle of the worm can be fed back to the drive circuit board of the motor in real time by the rotary encoder on the worm, and the travel of the nose can be controlled precisely.
Description
Technical field:
The present invention relates to mechanical field, relate in particular to electric spark machine tool, the particularly detection technique of the head position in electric spark machine tool, specifically a kind of improved head mobile drive deivce for spark-erosion machine tool.
Background technology:
Electric spark machine tool is in assembling process.Need to check the installation accuracy of head.Head is driven by a slide, and slide is arranged in a guide rail, and slide is driven by a screw mandrel, and screw mandrel drives rotation by hand crank conventionally.In order to reduce operating personnel's labour intensity.The applicant has proposed a kind of head mobile drive deivce of spark-erosion machine tool in CN20272802 Chinese patent, this device utilizes shaft coupling that screw mandrel is connected with the output shaft of a stepper motor, utilize with the drive circuit board of single-chip microcomputer and carry out Driving Stepping Motor action, by realize the movement of head to single-chip microcomputer input instruction, can reduce operating personnel's labour intensity.But because the output shaft of stepper motor all rotates a fixing angle in the time receiving each pulse signal of drive circuit board, therefore, the mobile accuracy of head is lower, and the moment of stepper motor is less, can not meet the check needs of large quality head.
Summary of the invention:
The object of the present invention is to provide a kind of improved head mobile drive deivce for spark-erosion machine tool, the described this improved head mobile drive deivce for spark-erosion machine tool will solve the less technical problem of mobile accuracy moment lower, stepper motor of the head mobile drive deivce of prior art spark-erosion machine tool.
This improved head mobile drive deivce for spark-erosion machine tool of the present invention, comprise machine tool frame and screw mandrel, described screw mandrel is connected with described machine tool frame by bearings mechanism, one end of screw mandrel is connected with the output shaft of a motor by transmission mechanism, described motor is relative with machine tool frame fixing, the control end of motor is connected with a drive circuit board, described drive circuit board includes single-chip microcomputer, wherein, described transmission mechanism comprises a gear and a worm screw, described gear and described worm engaging, gear is coaxially fixed on described screw mandrel, worm screw is connected with the output shaft of described motor by shaft coupling.
Further, the axial and worm screw of screw mandrel is axial vertical.
Further, one end of worm screw is connected with described machine tool frame by bearings mechanism, between worm screw and machine tool frame, is provided with rotary encoder, and described rotary encoder is connected with described drive circuit board by holding wire.
Further, described motor is stepper motor or servomotor.
Operation principle of the present invention is: motor rotates by worm drive screw mandrel, has greatly improved the displacement accuracy of head.Meanwhile, motor only need be exported less moment, just can drive the head of larger quality.
The present invention and prior art are compared, and its effect is actively with obvious.The present invention is provided with variable transmission mechanism between the output shaft of motor and the head of spark-erosion machine tool driving screw mandrel, has greatly improved the displacement accuracy of head, and motor only need be exported less moment, just can drive the head of larger quality.Meanwhile, utilize and be arranged on rotary encoder on worm screw, can be by the rotational angle Real-time Feedback of worm screw the drive circuit board to motor, be convenient to the stroke of meticulous control head.
