Use environment, traditional guide post nested structure are unable to satisfy above-mentioned application environment, while that there are stability is poor for existing guide column sleeve, rubs
Wipe larger, easy to wear, the problems such as service life is short.
Utility model content
In order to solve the above technical problems, the utility model provides a kind of high stability spiral guide column sleeve, in guide post ontology
The ball grooves of upper setting helical structure, while cooperating specific guide sleeve, it solves existing guide column sleeve and is unable to satisfy high-precision,
There is larger, easy to wear, the short problem of service life that rubs in the requirement of high stability.
In order to achieve the above objectives, the technical solution of the utility model is as follows: a kind of high stability spiral guide column sleeve, including leads
Column ontology, guide sleeve；Guide post ontology front end structure cylindrical, tail end are in flattened conical structure；In described this body surface of guide post
Face is provided with ball grooves, and the ball grooves are arranged around the guide post ontology, along the guide post ontology axial direction spiral winding；It is described
Guide sleeve is cylindrical；The guide sleeve is movably set on the guide post ontology, with the guide post ontology clearance fit；It is led described
Ball retaining hole is provided on the inner wall of set；Free ball is installed in the ball retaining hole；The free ball activity
It is arranged in the ball grooves；The outside of the guide sleeve is provided with annular positioning groove；Axis is installed in the annular positioning groove
It holds, the bearing holder (housing, cover) is set on the guide sleeve；It is set in the bearing outside and location and installation ring is installed, the location and installation ring phase
The guide sleeve is rotated.
As a kind of preferred embodiment of the utility model, the free ball be it is multiple, the free ball is led described in
The axial two sides for being alternately installed on the guide sleeve of column ontology.
As a kind of preferred embodiment of the utility model, the radius of free ball described in the radius ratio of the ball grooves is big
20-50μm。
As a kind of preferred embodiment of the utility model, the diameter of the free ball arrives for 1/10th of guide sleeve diameter
1/5th.
As a kind of preferred embodiment of the utility model, the guide post ontology is made of GCr15 steel.
As a kind of preferred embodiment of the utility model, the guide post body surface is provided with chrome layer.
Through the above technical solutions, the beneficial effect of technical solutions of the utility model is: the utility model structure is simply closed
Reason, easy for installation, using effect is good, has stability good, and advantage with high accuracy is different from existing guide column sleeve, this is practical new
While the guide sleeve of type is moved along guide post body length direction, circumferential rotation is carried out, this design can greatly improve guide sleeve fortune
Stability during row, and can effectively improve guide post ontology using interference fit between ball and guide post and match with guide sleeve
The precision of conjunction wears small, long service life.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only

Under, it is also possible to obtain other drawings based on these drawings.
Fig. 1 is the structural schematic diagram of the utility model.
Number and corresponding component title represented by letter in figure:
1. 2. guide sleeve of guide post ontology, 3. bearing
4. 5. ball grooves of location and installation ring.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without creative efforts
Every other embodiment obtained, fall within the protection scope of the utility model.
Embodiment
In conjunction with Fig. 1, the utility model discloses a kind of high stability spiral guide column sleeves, including guide post ontology 1, guide sleeve 2.It leads
1 front end of column ontology structure cylindrical, tail end are in flattened conical structure.Guide post ontology 1 is preferably made of GCr15 steel.In guide post
1 surface of ontology is provided with ball grooves 5, and ball grooves 5 wind setting around guide post ontology 1, along 1 axial screw of guide post ontology.Guide sleeve 2
