Abstract
The invention relates to a radial sliding table compact movement mechanism for a multi-spindle numerical control lathe. The radial sliding table compact movement mechanism for the multi-spindle numerical control lathe is characterized in that the head end or the tail end of a screw rod is fixedly arranged on a sliding table seat, and forms a static condition with a machine body; a numerical control motor is connected onto each nut, and is used for driving the corresponding nut to rotate relative to the screw rod so as to drive one corresponding feeding sliding plate to carry out screw rod axial movement. The radial sliding table compact movement mechanism for the multi-spindle numerical control lathe provided by the invention not only can compactly distribute radial sliding tables of the multi-spindle numerical control lathe, but also can independently adjust cutter compensation on each sliding table, and facilitates arranging more spindles on the multi-spindle numerical control lathe, so that the cost performance of equipment is improved.
Description
Technical field
The present invention relates to the radial direction slide unit motion of a kind of numerically controlled lathe, a kind of radial direction slide unit motion being applicable to many mainshaft digital controlled lathes.
Background technology
Along with development and the development of country's equipment manufacture, Digit Control Machine Tool is as the main product of machine tool industry, it has also become realize the key equipment of equipment manufacture modernization.Along with personalized, modular and fast-changing market demands, it is the most increasing to the demand of efficient, high reliability, the Digit Control Machine Tool of highly versatile, and the demand of many main shafts equipment is more and more vigorous；
But solve the compensation difficult problem that always this field does not solves carrying out high efficient and reliable that every cutter can be independent when tool changing or tool wear.
Summary of the invention
It is an object of the invention to provide a kind of compact layout that the radial direction slide unit of many mainshaft digital controlled lathes can be able to be carried out, can fix a cutting tool the mechanism compensated by each slide unit of independent regulation again.
In order to reach above-mentioned goal of the invention, the technical solution adopted in the present invention is: it is mainly made up of screw mandrel, nut, nut seat, feed slide, carriage saddle；It is provided with two or more feed slides on screw mandrel axis direction；Being provided with on screw mandrel and the nut of feed slide equal number, each nut is equipped with a nut seat；Nut seat is installed on feed slide, can confronting coaxial revolution when fine setting between nut seat and nut；It is characterized in that: the head end of screw mandrel or tail end are fixedly mounted on carriage saddle, it is resting state with body, all couple on each nut and have a numerical-control motor, be used for driving nut to be rotated relative to screw mandrel, thus drive feed slide to carry out screw mandrel axially-movable；The motor message that each numerical-control motor is sent during mending except tool changing and cutter by digital control system is identical；Carrying out the cutter added time in tool changing, system sends incomplete same motion value according to different tool offset value to each numerical-control motor, thus installs different abrasions and the installation length of cutter on the different slide unit that carries out making corrections.
As the further improvement of technique scheme, being mounted to angular contact bearings between described nut seat and nut, this structure can reduce the gap between nut seat and nut, and improves the speed of gyration of nut.
As the further improvement of technique scheme, described nut uses Timing Belt to couple with numerical-control motor, and this structure couples simple and reliable, and cost performance is high.
As the further improvement of technique scheme, described nut is arranged in the rotating shaft of numerical-control motor, and screw mandrel couples through numerical-control motor with nut, and numerical-control motor shell replaces nut seat to be installed on feed slide；The preferred hollow stepper motor of numerical-control motor in this structure, and directly can process screw thread in endoporus.This simple in construction, low cost.
As the further improvement of technique scheme, head end or the tail end one of described screw mandrel are fixedly mounted on carriage saddle, and it is tight that screw mandrel is carried out axial pre-terminated by other end elastomeric material and rolling bearing, preferential disk spring and angular contact bearing；This structure can improve the precision of screw mandrel, prevents thermal expansion.
When coupling with numerical-control motor due to feed screw nut, such as gear, Timing Belt, worm gear etc the kind of drive, their reciprocating rotating gap can be conditioned the least, but it the most still has revolution gap, these revolution gaps are for processing conventional hardware, being that relation is little, but require high part for some, it still can play relatively havoc effect；In order to alleviate these revolution gap impacts on processing, gyrodaming structure can be installed between feed screw nut and nut seat.
The invention has the beneficial effects as follows: the radial direction slide unit of many mainshaft digital controlled lathes can be carried out compact layout, can fix a cutting tool compensation by each slide unit of independent regulation again；Fixedly mounting additionally, due to screw mandrel, it is not required to do gyration, thus screw mandrel length just can allow longer, thus can increase slide unit number, makes equipment have more main shaft and processes simultaneously.
