Abstract
The utility model relates to a large carriage layout structure of a CNC face lathe, which comprises a bed body, a large carriage and a medium carriage. The large carriage is arranged on a steel guide rail on the bed body, the medium carriage is arranged on the large carriage, the two sides of the bed body are respectively provided with a vertical steel guide rail, the middle part of the bed body is also provided with at least one vertical steel guide rail, and the large carriage is horizontally arranged on the steel guide rails of the bed body. Compared with the prior art, with the 3-4 vertical guide rails on the bed body and the horizontal arrangement of the large carriage on the steel guide rails of the bed body, the utility model can significantly reduce the impact of the cutting force on the machine tool during cutting, and improve the stiffness of the tool holder, the machining precision of the machine tool and the manufacturing process.
Description
Technical field
The utility model relates to a kind of numerical control end surface lathe saddle arrangement.
Background technology
Numerical control end surface lathe saddle is lateral arrangement on two longitudinal rails of lathe bed outermost at present, when its shortcoming is machining large disk-like accessory external diameter, cutting point is in the lathe bed outside, cause disturbing moment excessive, must increase the auxiliary lathe bed supporting in the lathe bed outside, influence Product Cost Control, make assembly difficulty and strengthen, and cause the lathe floor space excessive.When the machining large disk like part end face, knife rest must hang the planker certain distance, whether crosses the part center otherwise influence cutting point, influences knife rest rigidity.
The utility model content
At the problems referred to above, the utility model provides a kind of numerical control end surface lathe saddle arrangement, to solve the problem of machining large disk-like accessory external diameter inconvenience in the prior art.
To achieve these goals, the technical solution of the utility model is as follows:
A kind of numerical control end surface lathe saddle arrangement, comprise lathe bed, saddle and middle carriage, described saddle is arranged on the steel guide rail of lathe bed, described middle carriage is arranged on the saddle, it is characterized in that, described lathe bed both sides respectively are provided with a steel guide rail longitudinally, and described lathe bed middle part also is provided with at least one steel guide rail longitudinally, and described saddle lateral arrangement is on the steel guide rail of lathe bed.
Further, in the utility model, the horizontal bearing face of described saddle and middle carriage all posts guide-soft-band.
Further, in the utility model, be connected by ball wire bar pair between described saddle and the middle carriage.
Further, in the utility model, the two ends of described saddle all are equipped with needle roller/cylindrical roller thrust bearing and the black box cover that is used for the rotating bearing ball screw pair.
Further, in the utility model, the two ends of described ball wire bar pair all are equipped with accurate locking nut.
Further, in the utility model, described lathe bed middle part is provided with a steel guide rail longitudinally.
Further, in the utility model, described lathe bed middle part is provided with two steel guide rails longitudinally.
The beneficial effects of the utility model are:
Compared with prior art, 3-4 bar longitudinal rail is set on the lathe bed of the present utility model, the saddle lateral arrangement is in the steel guide rail structure of lathe bed, cutting force was to the influence of lathe when this saddle arrangement can significantly improve cutting, improve knife rest rigidity, machine finish and improved anufacturability.
Description of drawings
Describe the utility model in detail below in conjunction with the drawings and specific embodiments:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Referring to Fig. 1, a kind of numerical control end surface lathe saddle arrangement mainly comprises lathe bed 10, saddle 5, middle carriage 6.On the lathe bed 10 of the present utility model longitudinal rail 8 is set, in the present embodiment, the longitudinal rail 8 on the lathe bed has three: the lathe bed both sides respectively are provided with a steel guide rail longitudinally, and lathe bed middle part also is provided with one (perhaps one or more) steel guide rail longitudinally.Saddle has heavy in section, high rigidity, and this saddle lateral arrangement can be slided along steel guide rail on three steel guide rails of lathe bed.Adopt this structure to play good stablizing effect to cutting big disk like part end face and external diameter.The mobile of saddle is to be driven by servomotor (not indicating among the figure), and this servomotor is connected with numerical control device by circuit.
In order further to optimize structure, pressing plate (not indicating among the figure) is housed on saddle, saddle lifts when preventing machining large disk-like accessory external diameter, if the long-term back of using finds that saddle is loosening, can regulate gag, every gag is fixed with two screws, and a screw is fastening, and another screw is regulated gag and moved.After adjusting finishes, should tighten the trip bolt of outside.
Be provided with the HIWIN ball screw 1 of ball wire bar pair at saddle, saddle 5 front and back ends are equipped with the screw mandrel transmission with ZARF series needle roller/cylindrical roller thrust bearing 2, and are furnished with DRS series seal receptacle assembly 3, are used to support HIWIN ball screw 1.Needle roller/cylindrical roller thrust bearing 2, black box equal 3 connect with the saddle flange, and have independent lubrication management to connect lubrication quill/cylindrical roller thrust bearing 2.The accurate locking nut 4 of ZAM series is used at HIWIN ball screw 1 two ends.Thereby the HIWIN ball screw drives and adopts drive motors to drive deceleration gear 9 drive HIWIN ball screw motions, and this drive motors is connected with numerical control device by circuit.
One nut seat 7 is installed on the middle carriage 6, and the nut 11 of ball wire bar pair is installed on this nut seat 7, and drive motors drives middle carriage 6 by this ball wire bar pair and vertically moves on saddle 5, and the middle carriage guide rail adopts the hard steel guideway of rectangle.
In addition, the horizontal bearing face of saddle and middle carriage all posts the Turcite-b guide-soft-band.
Cutting force had improved knife rest rigidity, machine finish and has improved anufacturability the influence of lathe when the utility model saddle arrangement can significantly improve cutting.
More than show and described basic principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in the foregoing description and the specification is principle of the present utility model; the utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these changes and improvements all fall in the claimed scope of the present utility model.The protection domain that the utility model requires is defined by appending claims and equivalent thereof.
