The lower surface at broaching tool mount pad two ends places on the rectangular guideway, and and rectangular guideway between be slidingly matched; The endoporus of broaching tool mount pad must be concentric with the broaching tool via hole of lathe bed casing one end end face; The installing hole that ball-screw is arranged on the ball-screw bearing; Lower surface at the ball-screw bearing is installed on the line slideway slide.
Fixing backing plate one middle side part have a pair of be parallel to each other and with the fixing parallel guiding rail in limit, two ends of backing plate; The length of this guiding rail extends to fixedly backing plate middle part by the fixing limit of backing plate.
Mobile backing plate middle part have with fixing backing plate on the corresponding guide rail chute of guiding rail; Be distributed with the via hole of mobile backing plate set bolt in guide rail chute both sides.
Fixedly backing plate is fixed on fixedly on the backing plate datum clamp face; The guide rail chute of mobile backing plate is fixed on the guiding rail on the fixing backing plate, and is fixed on the fixedly upper surface of backing plate by mobile backing plate set bolt.
Tooth form synchronous belt pretension leading screw is positioned at mobile backing plate upper surface middle part, and an end is installed in the axis hole of bearing, and the other end is installed in the screw; Bearing is fixed on the fixedly upper surface of backing plate, and screw is fixed on mobile backing plate upper surface; AC servo motor is fixed on mobile backing plate upper surface.
Planetary reducer in the transmission system is fixed on mobile backing plate upper surface by the reductor set bolt; The axle of planetary reducer one end is packed in the torque limiter; Small pulley is sleeved on the excircle of torque limiter; The small pulley support is installed in mobile backing plate upper surface by the small pulley bracket fixing bolt; The inner ring sleeve of single-row tapered roller bearing is on the axle of small pulley support, and outer shroud is packed in the torque limiter, and fixes by circlip for hole that is positioned at the small pulley rack shaft hole and the circlip for shaft that is positioned on the axle; The axle of the planetary reducer other end is connected with the axle of AC servo motor.
Because the present invention takes technique scheme, has following characteristics:
1, employing is installed on AC servo motor, decelerator on the mobile backing plate at lathe bed rear portion on the mounting means, separates with lathe bed, has avoided the operation because of the vibration effect lathe, improves the lathe running stability.2, adopt non-maintaining AC servo motor and decelerator, safeguard that simply use cost is lower.3, device security protectiveness height.Because mounting torque limiter on the belt wheel of driving-chain, in case when breaking down, motor can produce with belt wheel and skid, and avoids causing the person and equipment to injure.4, owing to adopt its maximum speed of AC servo motor can reach 5000 rpms, be higher than general alternating current generator far away, so broaching speed is fast, high efficiency.
