The groove that mill flower is bored and the processing of land, the method that prior art adopts usually has: 1, processed respectively by spline grinder and land grinding machine, and not only equipment investment is many for they, occupation area of equipment large, and labor intensive is many, working (machining) efficiency is low; 2, by numerical control grinding Cutter Body Processing with Machining Center, this method arranges multiple emery wheel in a device, and a kind of emery wheel completes a grinding process, because emery wheel cannot automatic dressing, and therefore can not continuous seepage; In addition, its manufacturing procedure first processes groove, then carries out the grinding of land and the knife back after automatic tool changer again, and therefore its working (machining) efficiency is still lower, and its apparatus expensive, is difficult to extensive use simultaneously.
Fluted drill groove and land modular grinding machine (application number: 201220614374.9) disclosed in Chinese patent literature, include a main shaft, front-end of spindle is provided with can the chuck of clamping workpiece, main shaft part be connected with can drive shaft feeding, rotation and calibration power set, main shaft front is provided with can by workpiece spindle to be processed to the feed arrangement sending into chuck; A land abrasive grinding wheel and a groove grinding emery wheel is respectively arranged with in the both sides of chuck front Working position, land abrasive grinding wheel and groove grinding emery wheel are driven by respective dynamical system respectively, the rotating shaft of land abrasive grinding wheel and main axis parallel, there is between the rotating shaft of groove grinding emery wheel and main shaft an inclination angle adapted with fluted drill helical angle, but this feed arrangement is hydraulic cylinder, therefore when workpiece is released by hydraulic cylinder, because the displacement released is longer, therefore the piston rod of hydraulic cylinder easily produces skew, and therefore feeding is comparatively inaccurate.
Summary of the invention
The purpose of this utility model there are the problems referred to above for existing technology, propose a kind of can the automatic pusher of accurate feeding.
The purpose of this utility model realizes by following technical proposal: automatic pusher, the polished rod comprising base and be axially connected on described base, it is characterized in that, described base is also provided with the screw mandrel be arranged in parallel with described polished rod, described screw mandrel has been threaded ball screw, described ball screw is fixed with fixed block, described fixed block is connected mutually with described polished rod, described base is also provided with motor, the rotating shaft of described motor is connected mutually with described screw mandrel, described base comprises base plate, the two ends of described base plate are parallel is provided with riser, the sidewall of described riser is all equipped with ball bearing guide bushing and described ball bearing guide bushing is connected mutually with described riser, described polished rod is all through described ball bearing guide bushing.
When pusher, rotated by driven by motor screw mandrel, the rotation of screw mandrel drives ball screw to move linearly, ball screw drives polished rod to axially move by fixed block, due to polished rod all through the ball bearing guide bushing be arranged on riser, therefore make the axle phase shift of polished rod have good axiality, avoid producing because stroke is long bending, there is the good advantage of transmission effect, there is feeding advantage comparatively accurately.
In above-mentioned automatic pusher, described ball screw is between two risers and described ball screw and described fixed block are screw thread is connected.Ball screw is connected with fixed block screw thread, has the advantage that structure is simple and easy to connect, and ball screw, between two risers, limits the shift position of ball screw, has and uses conveniently advantage.
In above-mentioned automatic pusher, for shaft coupling is connected between the rotating shaft of described motor and described screw mandrel.Rotating shaft and the screw mandrel of motor are that shaft coupling is connected, and have easy to connect and that transmission efficiency is higher advantage.
In above-mentioned automatic pusher, one end of described ball bearing guide bushing has annular convex shoulder, and described riser is provided with the installing hole passed for ball bearing guide bushing, and the aperture place of described installing hole is provided with convex rank, and described annular convex shoulder is resisted against on described convex rank.The annular convex shoulder of ball bearing guide bushing is resisted against on convex rank, has the good advantage of locating effect.
In above-mentioned automatic pusher, the outside of described riser is fixed with tubular mount pad, and the housing of described motor is connected on described mount pad.
Compared with prior art, this automatic pusher has the following advantages:
1, by the rotation of driven by motor screw mandrel, ball screw is moved linearly, ball screw drives polished rod to axially move by fixed block, because the two ends of polished rod are all through the ball bearing guide bushing be arranged on riser, therefore the axle phase shift of polished rod is made to have good axiality, avoid producing because stroke is long and bend, there is the good advantage of transmission effect;
2, ball screw is connected with fixed block screw thread, has the advantage that structure is simple and easy to connect, and ball screw, between two risers, limits the shift position of ball screw, has and uses conveniently advantage;
3, the rotating shaft of motor is that shaft coupling is connected with screw mandrel, has easy to connect and that transmission efficiency is higher advantage.
