Description
Technical field
The present invention relates to a kind of digital control plane milling and boring machine, relate in particular to the symmetrical guide rail side of a kind of horizontal boring axle ball screw for feeding supporting construction.
Background technology
The feeding of boring processing request boring axle will have high rigidity, high accuracy, and along with the development of new material, new product, new technology, the rate request of boring processing is also being improved gradually.
Common boring machine axis feeding is generally promoted by the support of boring shaft tail end, the tail pipe of support and boring shaft tail end is for being slidably connected, guide rail is generally common hard rail, the movement of support has general T type leading screw to drive, and the power of T-shaped leading screw is to be passed and come by the multi-stage gear in transmission system by common electric machine.Problem is 1, hard rail location exists pressing plate and wedge, and location can be subject to the restriction of technological level and operative skill, is difficult to arrive high degree of rigidity and precision, and of long duration can produce wearing and tearing, needs accuracy resumption, and rigidity and precision all can be greatly affected; 2, feeding power is provided by common electric machine, and in order to meet the selection of multistage feed speed, gear transmission chain is longer, and it is more loaded down with trivial details to operate; 3, common T-shaped lead screw transmission precision is not high, and idle running amount is larger, and transmission speed can not improve, and cannot meet the user's request day by day improving.
Summary of the invention
The object of this invention is to provide a kind of symmetrical guide rail side of horizontal boring axle ball screw for feeding supporting construction that can improve bore hole precision.
For achieving the above object, the technical solution used in the present invention is: the symmetrical guide rail side of a kind of horizontal boring axle ball screw for feeding supporting construction, comprise the pillow that breaks away, in sideslip pillow, boring axle is installed, the front end bottom of sideslip pillow is fixedly connected with main electric machine support, in main electric machine support, be installed with main motor and gearbox, the tail end of gearbox is fixedly connected with main electrical machine belt pulley, on main electrical machine belt pulley, be connected with described boring axle by main motor synchronous belt, it is characterized in that: described boring shaft tail end is fixedly connected with support by bearing, on support, be connected with slide block, the pillow afterbody inner surface that breaks away is fixedly connected with two line slideways, two line slideways are symmetrically distributed in the both sides of described boring axle, described slide block is corresponding with described line slideway, the tail end of resting the head on that breaks away is fixedly connected with feeding motor outward, feeding electrical machine belt pulley is installed on feeding motor, feeding electrical machine belt pulley is connected with synchronous pulley by feeding Timing Belt, on synchronous pulley, be connected with leading screw, leading screw is positioned at the pillow that breaks away, screw has been threaded on leading screw, screw is fixedly connected with described support.
Advantageous effect of the present invention is: due to this structure of the present invention, line slideway for being arranged symmetrically with between the support of boring axle feeding and main spindle box body, so use good rigidly of the present invention, translational speed is fast, and wearing and tearing are few, precision stability is good, and feed system driving-chain is short, power is provided by servomotor, fast response time, transmission accuracy is high, and the convenient amount of feeding of controlling.
