Description
Technical field
The present invention relates to a kind of ball screw bearing arrangement, belong to mechanical equipment technical field.
Background technology
Ball-screw bearing is used in a lot of plant equipment, and especially on lathe, its effect is will to rotate
Motion.Along with the development of process technology, the accuracy of manufacture of ball screw bearing has reached comparison level, so that product adds
Work precision is higher, and the installation accuracy of ball screw bearing is also a highly important factor.The peace of ball-screw bearing at present
Dress mode typically has three kinds, be respectively (1) one end fix, one end freely；(2) one end fix, one end movable；(3) two ends are fixed.
For the third mounting means, machining accuracy is the highest, but installation requirement is the highest, and the axle head of screw mandrel needs by a nut
Being adjusted, then install location, but the mounting means of existing product is more inconvenient, screw mandrel location is relatively difficult.
Summary of the invention
For solving the problems referred to above, the present invention provides a kind of simple in construction, ball screw bearing arrangement easy for installation.
The present invention solves that its problem be the technical scheme is that
A kind of ball screw bearing arrangement, the screw mandrel including bearing block, being arranged on described bearing block and be arranged on institute
Stating the bearing between bearing block and described screw mandrel, the end of described screw mandrel is provided with pressure regulating mechanism, described pressure regulating mechanism
Including slide block, the fixture block being arranged in described slide block that can slide on described screw mandrel and promote described fixture block to described screw mandrel
The thrust spring of movement, the outer peripheral face of described screw mandrel is provided with the chute corresponding with described slide block, and described chute bottom surface is provided with and institute
State the draw-in groove that fixture block is corresponding；Compression spring, the end of described screw mandrel, position it is provided with between described pressure regulating mechanism and described bearing
Outside screw in described pressure regulating mechanism is provided with adjusting nut.
Preferably, it is provided with pad between described compression spring and described bearing.
Preferably, the outer sheath of described screw mandrel is equipped with end cap.
The invention has the beneficial effects as follows: simple in construction, easy to operate, pass through pressure regulating mechanism, using the teaching of the invention it is possible to provide one is pre-
Clamp force, the installation to screw mandrel easily is adjusted, and tightens adjusting nut the most again, carries out position and fixes.
Accompanying drawing explanation
The invention will be further described with embodiment below in conjunction with the accompanying drawings:
Fig. 1 is the structural representation of the present invention.
In figure: 1, bearing block；2, screw mandrel；3, bearing；4, slide block；5, fixture block；6, thrust spring；7, chute；8, draw-in groove；9、
Compression spring；10, adjusting nut；11, projection；12, pad；13, end cap.
Detailed description of the invention
A kind of ball screw bearing arrangement as shown in Figure 1, including bearing block 1, the silk that is arranged on described bearing block 1
Bar 2 and be arranged on the bearing 3 between described bearing block 1 and described screw mandrel 2, the end of described screw mandrel 2 is provided with pressure regulation machine
Structure, described pressure regulating mechanism includes the slide block 4 that can slide on described screw mandrel 2, the fixture block 5 that is arranged in described slide block 4 with
And promoting the thrust spring 6 that described fixture block 5 moves to described screw mandrel 2, it is right with described slide block 4 that the outer peripheral face of described screw mandrel 2 is provided with
The chute 7 answered, described chute 7 bottom surface is provided with the draw-in groove 8 corresponding with described fixture block 5, and draw-in groove 8 can arrange multiple, with correspondence not
Same pressure.It is provided with compression spring 9 between described pressure regulating mechanism and described bearing 3, the end of described screw mandrel 2, is positioned at institute
The outside screw stating pressure regulating mechanism is provided with adjusting nut 10.Fixture block 5 can operate from the outside of slide block 4, when needing
When wanting sliding slider 4, pull the projection 11 of fixture block 5 end, when slide block 4 arrives set position, discharge fixture block 5,
Under the effect of thrust spring 6, fixture block 5 can snap in draw-in groove 8, during slide block 4 moves, can compress or unclamp pressure bullet
Spring 9, thus the regulation active force from compression spring 9 suffered by screw mandrel 2 very easily, and after slide block 4 is had good positioning,
Adjusting nut 10 also is able to be threaded in or out easily.It is provided with pad 12 between described compression spring 9 and described bearing 3,
To improve the mounting stability of compression spring 9.The outer sheath of described screw mandrel 2 is fixed equipped with end cap 13, the end of described end cap 13
It is arranged on bearing block 1, to play protection bearing 3 and the effect of pressure regulating mechanism.
The above, the only present invention preferably detailed description of the invention, but protection scope of the present invention is not limited thereto,
Any those familiar with the art in the technical scope that the invention discloses, according to technical scheme and
Inventive concept equivalent or change in addition, all should contain within protection scope of the present invention.
