Background technology
General numerically controlled lathe is single main shaft hilted broadsword holder structure, in order to improve working (machining) efficiency further, constantly occur the two main shaft hilted broadsword seats of single main shaft knife-seat, Z-direction etc. in industry, the two main shaft hilted broadsword seat feature of Z-direction is two spindle face opposites, and tool rest can along X to, Z-direction way moving in centre.Machining accuracy is low on the one hand for this lathe, and tool rest needs constantly mobile, operation inconvenience, and production efficiency is low.
Summary of the invention
The object of the invention is to: design the numerically controlled lathe that a kind of single mair motor drives two main shaft, to enhance productivity, improve accuracy.
The present invention includes base and workbench, its technical scheme comprise driven by same spindle motor, be parallel to each other the first main shaft side by side and the second main shaft, its processing end is positioned at the same side and position is corresponding, workbench is provided with two corresponding with the first main shaft and the second spindle processing end respectively tool rests, tool rest is arranged on same workbench, workbench with make it make X to be connected to the driving mechanism of walking with base.
For making the first main shaft consistent further with the second shaft motion, they can be arranged on the slide of same Z-direction movement, slide is connected with main axle moving motor.
In addition, for convenience of tool rest location, can be corresponding with corresponding main spindle's, and also two tool rests are kept strokes, and at least one tool rest is connected with workbench by adjustable mechanism, also tool rest can be designed to fine-tuning form, to adjust.
The fine-tuning tool rest of following structure can be adopted: it mainly comprises its base and is arranged on the push type broach platform on base in the present invention, base is made up of its upper bed-plate and lower bottom base, the upper surface band of lower bottom base is fluted, the screw mandrel that two ends are arranged on its sidewall is arranged in groove, the lower surface of upper bed-plate is provided with screw, and screw is connected with wire rod thread.
By this structure, the position of push type broach platform can be adjusted by rotary screw, regulate the position of the cutter hub on it further, to reach object of the present invention.
In the present invention, the fit system of upper bed-plate and lower bottom base has various ways, but makes stable for it, by be arranged in surface both and the dovetail slide unit cooperatively interacted and dovetail groove coordinate, dovetail slide unit and dovetail groove parallel with screw mandrel.
After cutter hub position is determined, should lock it, for the structure of dovetail groove of the present invention and dovetail slide unit, can dovetail slide unit be arranged on lower bottom base, the width of dovetail groove is greater than the width of dovetail slide unit, in the side of dovetail slide unit, latch segment is housed, and has and screw in dovetail groove sidewall and the locking nut be rotatably assorted with clamp holder.
For said structure, preferably the groove installing screw mandrel is arranged on the upper surface of dovetail slide unit, and the screw be attached thereto is arranged on the bottom surface of dovetail groove.
For convenience of the adjustment of cutter hub height, between push type broach platform and upper bed-plate, pad can also be housed.
In addition, be provided with groove above upper bed-plate, and be bolted positioning key, push type broach platform has the groove corresponding with positioning key position.This positioning key can in order to determine the relative position between push type broach platform and upper bed-plate.
And the bottom surface of lower bottom base is provided with groove, and be bolted the feather key protruding from lower bottom base bottom surface, feather key coordinates with the inverted T-slot on workbench.
Because two main shafts of the present invention are driven by same motor, therefore, it starts, stop and the situation of rotation all consistent, and the action due to corresponding two upper cutter heads is also consistent, therefore, utilizes the present invention can process two identical parts simultaneously.In addition, tool rest is divided into a few part by the present invention, thus can realize the adjustment of its height and the adjustment to its lateral attitude.Realize the adjustment of the position of tool setting thus, it can be made accurately to coordinate with part to be processed on the one hand, on the other hand, when there being multiple cutter to operate simultaneously, the uniformity of each work pieces process can be ensured, thus ensure product quality.
