Abstract
The utility model discloses a be applied to bearing frame structure of CNC machining center Z axle, including the stand that is the tower form, the lead screw that is vertical layout is installed to the stand upper end, and the lead screw is installed in the bearing frame upper end that lies in the stand upper end, and the tip is provided with at least two strengthening rib strips that are the triangle -shaped form, strengthening rib strip connecting axle bearing and stand under the bearing frame. The utility model has the advantages of novel in design, simple structure, the improvement is the whole rigidity of lathe, has reduced this set process of assembly, has improved assembly efficiency greatly, has also reduced the cost of labor simultaneously, has improved precision of the machine.
Description
Technical field
The utility model is related to machining center technical field, more particularly, to a kind of bearing being applied to cnc machining center z-axis
Holder structure.
Background technology
Machining center servo motor axially can be divided into three axles, is respectively: xyz axle, and an important function of bearing block is just
It is fixed conveyor motor, motor driven screw body, thus drive be supported on motion！Bearing block design and the reasonability installed are straight
Connect the positioning having influence on lathe and repetitive positioning accuracy.Common lathe z-axis bearing block design is separation design mode, this
Design has a following problem: first: rigidity is poor；Second: installation accuracy the poor 3rd: bring a set of to assembling
Operation.
Utility model content
The purpose of this utility model is to provide one kind to be applied to cnc machining center z-axis for the deficiencies in the prior art
Bearing block structure, this bearing block structure is novel in design, structure is simple, and raising is the integral rigidity of lathe, decrease assembling this
A set of operation, substantially increases efficiency of assembling, also reduces cost of labor simultaneously, improve machine tool accuracy.
For reaching above-mentioned purpose, the utility model is achieved through the following technical solutions.
A kind of bearing block structure being applied to cnc machining center z-axis, includes in tower-like column, and column upper end is installed
Have in the screw mandrel that is vertically arranged, screw mandrel is installed in the bearing block upper end positioned at column upper end, bearing block bottom be provided with to
The strengthening rib strip of few two triangular shape, strengthening rib strip connects bearing block and column.
Wherein, described screw mandrel upper end is equiped with driving motor.
Wherein, described screw mandrel bottom is equiped with the bearing support block positioned at described column lower end portion.
Wherein, described bearing block and strengthening rib strip and column are formed in one structure.
Wherein, the angle a between described strengthening rib strip and described bearing block is 110-130 °.
Wherein, described bearing block bottom is provided with four strengthening rib strips.
The beneficial effects of the utility model are: a kind of bearing being applied to cnc machining center z-axis described in the utility model
Holder structure, includes in tower-like column, and column upper end is equiped with the screw mandrel being vertically arranged, and screw mandrel is installed on column
The bearing block upper end of end, bearing block bottom is provided with the strengthening rib strip of at least two triangular shape, and strengthening rib strip connects
Bearing block and column.The utility model has modern design, structure simply, and raising is the integral rigidity of lathe, decreases assembling
This set of operation, substantially increases efficiency of assembling, also reduces cost of labor simultaneously, the advantage that improve machine tool accuracy.

3 bottoms are provided with the strengthening rib strip 31 of at least two triangular shape, and strengthening rib strip 31 connects bearing block 3 and column 1.
Further, described screw mandrel 2 upper end is equiped with driving motor 21.
Further, described screw mandrel 2 bottom is equiped with the bearing support block 22 positioned at described column 1 bottom.
As the present embodiment preferably, described bearing block 3 and strengthening rib strip 31 and column 1 are formed in one structure.
Further, the angle a between described strengthening rib strip 31 and described bearing block 3 is 110-130 °, and the present embodiment is excellent
The angle a of choosing is 120 °.
As the present embodiment preferably, described bearing block 3 bottom is provided with four strengthening rib strips 31.
Need to further explain, the utility model adopt bearing block 3 bottom setting strengthening rib strip 31 and bearing block 3 with
Strengthening rib strip 31 and column 1 are formed in one the structure design of structure, and it has, and modern design, structure are simple, and raising is lathe
Integral rigidity, decrease assembling this set of operation, substantially increase efficiency of assembling, also reduce cost of labor simultaneously, improve
The advantage of machine tool accuracy.
Above content is only preferred embodiment of the present utility model, for those of ordinary skill in the art, according to this reality
With new thought, all will change in specific embodiments and applications, this specification content should not be construed as
To restriction of the present utility model.
