Abstract

The utility model discloses the tailstock structure that a kind of centre-height is adjustable, belong to machine tool field.Comprise tailstock, tailstock is provided with uninfluenced tailstock mandrel, tailstock mandrel is provided with axis hole, eccentric taper sleeve is provided with in the axis hole of tailstock mandrel, eccentric throw is there is between the center line of tailstock mandrel and the center line of eccentric taper sleeve, eccentric taper sleeve outer face is provided with the long gain of arc, and eccentric taper sleeve is by being fixed on tailstock mandrel through the screw of gain.The utility model does not need to change the height that slide of tail stock bottom just can realize adjusting tailstock mandrel, has the advantage that cost is low, simple to operate.

Description

The tailstock structure that centre-height is adjustable
Technical field
The utility model belongs to a kind of machine tool component, specifically, particularly relates to the tailstock structure that a kind of centre-height is adjustable.
Background technology
At present, the top of tail stock part is being all be contained in a uninfluenced tailstock mandrel, the center height of tailstock mandrel is fixing, when after slide of tail stock bottom wearing and tearing and then after causing tailstock body center height step-down, slide of tail stock bottom can only be changed, therefore to there is replacement cost high for prior art, and the defect wasted time and energy.
Summary of the invention
The utility model object is to provide the adjustable tailstock structure of a kind of centre-height, high when changing slide of tail stock bottom cost after slide of tail stock bottom wearing and tearing to overcome in prior art, and the defect wasted time and energy.
For solving the problem, the utility model is by the following technical solutions: the tailstock structure that a kind of centre-height is adjustable, comprise tailstock, tailstock is provided with uninfluenced tailstock mandrel, tailstock mandrel is provided with conical bore, is provided with eccentric taper sleeve in the conical bore of tailstock mandrel, there is eccentric throw between the center line of eccentric taper sleeve and the center line of tailstock mandrel, eccentric taper sleeve outer face is provided with the gain of arc, and eccentric taper sleeve is by being fixed on tailstock mandrel through the screw of gain.
The eccentric throw of eccentric taper sleeve center line is 1mm.
Eccentric taper sleeve is Mohs No. 3 eccentric taper sleeves.
Compared with prior art, the beneficial effects of the utility model are: the utility model installs an eccentric taper sleeve in tailstock mandrel, when after slide of tail stock bottom wearing and tearing, the centre-height of tailstock mandrel can change, only need to rotate eccentric taper sleeve and just can allow the center of conical bore is high to change, thus it is high to change top center, make that top center is high remains on the height before wearing and tearing, do not need to change the height that slide of tail stock bottom just can realize adjusting tailstock mandrel, there is the advantage that cost is low, simple to operate.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is that the A-A of Fig. 1 is to sectional view;
Fig. 3 is the I portion enlarged drawing of Fig. 1.
In figure: 1, tailstock mandrel; 2, screw; 3, eccentric taper sleeve; 4, tailstock; 5, gain.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described:
As shown in Figure 1 and Figure 2, the tailstock structure that a kind of centre-height is adjustable, comprise tailstock 4, tailstock 4 is provided with uninfluenced tailstock mandrel 1, tailstock mandrel 1 is provided with conical bore, be provided with eccentric taper sleeve 3 in the conical bore of tailstock mandrel 1, there is eccentric throw between the center line of eccentric taper sleeve 3 and the center line of tailstock mandrel 1, the eccentric throw of eccentric taper sleeve 3 center line is preferably set to 1mm; Eccentric taper sleeve 3 is Mohs No. 3 eccentric taper sleeves.
As shown in Figure 3, eccentric taper sleeve 3 outer face is provided with the gain 5 of arc, and eccentric taper sleeve 3 is fixed on tailstock mandrel 1 by the screw 2 through gain 5.
When tailstock 4 centre-height needs to regulate, as long as unclamp screw 2, rotate with hand the centre-height adjustment that eccentric taper sleeve 3 can realize tailstock 4, when being adjusted to the position of needs, tighten screw 2.
