Description

Axial location draws the clamping device that rises
Technical field
The present invention relates to a kind of converted products that is mainly used in axially to need the lathe of hi-Fix and special processing equipment draw the clamping device that rises, especially a kind of axial location draws the clamping device that rises.
Background technology
At present, the domestic axial location generally applied opens a step at gripping sleeve, in fact this step is variation displacement in clamping process, axial location precision is low, the product of processing axially changes and sometimes reaches more than 0.15mm, being less than 0.05mm to ensure that the product processed axially changes, needing to redesign clamp system.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of can ensure converted products axially variation be less than 0.05mm and the high axial location of precision draws the clamping device that rises.
According to technical scheme provided by the invention, described axial location draws the clamping device that rises, comprise adapter sleeve, holder, end cap and gripping sleeve, end cap is fixed with at the front end face of holder, adapter sleeve is provided with at the rear end face of holder, stationary positioned plug is had at holder internal fixtion, the stage casing cylindrical of stationary positioned plug has circular fin, and adapter sleeve, the circular fin of stationary positioned plug and gripping sleeve are fixed as one by transmission screw, the cylindrical of leading portion barred body of the circular fin of stationary positioned plug coordinates with the inner circle of gripping sleeve, the front end of gripping sleeve has outer conical surface, the circular cone bottom surface of described outer conical surface is positioned on the front end face of gripping sleeve, the front end of end cap has internal conical surface, the circular cone bottom surface of described internal conical surface is positioned on the front end face of end cap, outer conical surface on gripping sleeve coordinates with the internal conical surface on end cap.
Pad is provided with between the rear end face and the circular fin of stationary positioned plug of gripping sleeve.
Reinforcing sleeve is fixed with in the leading section of end cap.
Middle stationary positioned plug is fixed on and is directly connected with machine tool on holder by the present invention, ensures and machine tool one, ensure that positioning datum is constant, thus ensure that the axial variation of converted products is less than 0.05mm; And gripping sleeve internal diameter and stationary positioned plug external diameter precision-fit, ensure that converted products circular runout is less than 0.05mm.And draw the clamping force that rises to realize effectively transmitting by adapter sleeve, transmission screw, gripping sleeve and the wedging of end cap inclined-plane.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the A-A sectional view of Fig. 1.
Detailed description of the invention
Below in conjunction with concrete drawings and Examples, the invention will be further described.
As shown in the figure: this axial location draws the clamping device that rises, comprise adapter sleeve 1, holder 2, end cap 3 and gripping sleeve 5, end cap 3 is fixed with at the front end face of holder 2, adapter sleeve 1 is provided with at the rear end face of holder 2, stationary positioned plug 8 is had at holder 2 internal fixtion, the stage casing cylindrical of stationary positioned plug 8 has circular fin, and adapter sleeve 1, circular fin and the gripping sleeve 5 of stationary positioned plug 8 are fixed as one by transmission screw 7, the cylindrical of the leading portion barred body of the circular fin of stationary positioned plug 8 coordinates with the inner circle of gripping sleeve 5, the front end of gripping sleeve 5 has outer conical surface, the circular cone bottom surface of described outer conical surface is positioned on the front end face of gripping sleeve 5, the front end of end cap 3 has internal conical surface, the circular cone bottom surface of described internal conical surface is positioned on the front end face of end cap 3, outer conical surface on gripping sleeve 5 coordinates with the internal conical surface on end cap 3.
Pad 4 is provided with between the rear end face and the circular fin of stationary positioned plug 8 of gripping sleeve 5.
Reinforcing sleeve 6 is fixed with in the leading section of end cap 3.
Present invention employs the structural design that centre is fixed location mandril 8, middle stationary positioned plug 8 is screwed and is directly connected with machine tool on holder 2, ensure and machine tool one, end cap 3 is screwed on holder 2, and end cap 3 front end is strengthened with reinforcing sleeve 6 is fixing; The internal diameter of gripping sleeve 5 and the external diameter precision-fit of stationary positioned plug 8, and be connected with adapter sleeve 1 by transmission screw 7.
The front end outer wall of the gripping sleeve 5 in the present invention is coordinated by inside and outside circle conical surface face with the front end outer wall of end cap 3.
The present invention is provided with adjustment pad 4, can align the displacement of gripping sleeve 5.
During work of the present invention, the clamping force that rises is drawn to realize effectively transmitting with the inside and outside circle conical surface wedging of end cap 3 by adapter sleeve 1, transmission screw 7, gripping sleeve 5.
