Description
Technical field
The utility model relates to a kind of digital control plane milling and boring machine, relates in particular to the sleeping boring and milling head outer lifting common guide rails of a kind of crossbeam and bilateral and ball screw arrangement.
Background technology
The tradition numerical control gantry machining center series crossbeam of lathe and the driving of the horizontal boring and milling head outer lifting of side are by two ball-screw auxiliary driving, and rotate and drive screw by ball-screw, thereby drive crossbeam and side horizontal milling head to do separately catenary motion, two ball-screws not only take more spaces, and due to ball-screw High Rotation Speed, will produce and beat and noise, and can damage ball screw assembly, self, thereby affect machine finish.
Summary of the invention
The purpose of this utility model is to provide a kind of lifting stability that can increase can improve again the crossbeam of machine finish and the sleeping boring and milling head outer lifting common guide rails of bilateral and ball screw arrangement.
For achieving the above object, the technical solution adopted in the utility model is: the sleeping boring and milling head outer lifting common guide rails of a kind of crossbeam and bilateral and ball screw arrangement, comprise column, the front surface left and right sides of column is fixedly connected with respectively wired rail, line rail slides up and down and connects wired rail slide block, line rail slide block front surface is fixedly connected with crossbeam, it is characterized in that: on column, be fixedly connected with ball-screw, ball-screw upper and lower be threaded respectively the first screw and the second screw, the first screw and the second screw are double-decker, between double-decker, by bearing, connect, the front surface of the first screw is fixedly connected with described crossbeam, on the first screw, be socketed with driven gear, on driven gear, be engaged with driving gear, on driving gear, be fixedly connected with the first planetary gear reduction box, on the first planetary gear reduction box, be connected with the first servomotor, the front surface of the second screw is fixedly connected with the horizontal boring head of side, on the internal layer of the second screw, be socketed with driven gear, driven gear is engaged with driving gear, on driving gear, be fixedly connected with the second planetary gear reduction box, on the second planetary gear reduction box, be fixedly connected with the second servomotor.
In this structure, be also fixedly connected with beam balance oil cylinder on described column, the upper end of described beam balance oil cylinder is connected with described crossbeam.
The utility model has the advantages of and be: due to this structure of the present utility model, in the time of cleverly by crossbeam and the horizontal boring head bridging line of side rail, share a ball-screw and drive separately, screw rotates separately, leading screw is fixed, when realizing the horizontal boring head catenary motion of crossbeam and side, reduced the quantity of transport ball screw, dwindle transmission space, so use beating and noise that the utility model can avoid that ball-screw High Rotation Speed causes, thereby improved the stability of machine finish and lathe.
