Abstract
The utility model relates to an axial-location pull-expansion clamping device. An end cover is fixedly arranged on the front end face of a fixed seat, a connecting sleeve is arranged on the rear end face of the fixed seat, a fixed locating core rod is fixedly arranged in the fixed seat, annular protruding arrises are arranged on the outer circle of the middle section of the fixed locating core rod, and the connecting sleeve, the annular protruding arrises of the fixed locating core rod and a clamping sleeve are fixed as a whole through drive screws. The outer circle of the front section rod body of the annular protruding arrises of the fixed locating core rod is matched with the inner circle of the clamping sleeve, an outer circular conical surface is arranged at the front end of the clamping sleeve, and the circular cone bottom face of the outer circular conical surface is located on the front end face of the clamping sleeve. An inner circular conical surface is arranged at the front end of the end cover, the circular cone bottom face of the inner circular conical surface is located on the front end face of the end cover, and the outer circular conical surface of the clamping sleeve is matched with the inner circular conical surface of the end cover. According to the axial-location pull-expansion clamping device, the fact that the axial fluctuation of processed products is smaller than 0.05mm can be guaranteed, and pull-expansion clamping force is effectively transmitted through the fact that the connecting sleeve, the drive screws, the clamping sleeve and the end cover are wedged tightly through the inner circular conical surface and the outer circular conical surface.
Description
Technical field
The utility model relates to a kind of converted products that mainly is used in and axially needs the clamping device that rises that draws on the lathe of hi-Fix and the special processing equipment, and especially a kind of axial location is drawn the clamping device that rises.
Background technology
At present, the domestic axial location of generally using is to open a step at gripping sleeve, in fact this step is the change displacement in clamping process, the axial location precision is low, the axial change of product of processing sometimes reaches more than the 0.15mm, for the product that guarantees to process axially changes less than 0.05mm, need the redesign clamp mechanism.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of can guarantee converted products axially change draw the clamping device that rises less than 0.05mm and the high axial location of precision.
The technical scheme that provides according to the utility model, described axial location is drawn the clamping device that rises, comprise adapter sleeve, holder, end cap and gripping sleeve, front end face at holder is fixed with end cap, rear end face at holder is provided with adapter sleeve, in holder, be fixed with the stationary positioned plug, has circular fin on the stage casing cylindrical of stationary positioned plug, and adapter sleeve, circular fin and the gripping sleeve of stationary positioned plug are fixed as one by the transmission screw, the cylindrical of the leading portion barred body of the circular fin of stationary positioned plug cooperates 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, and the outer conical surface on the gripping sleeve cooperates with internal conical surface on the end cap.
Between the circular fin of the rear end face of gripping sleeve and stationary positioned plug, be provided with pad.
Leading section at end cap is fixed with reinforcing sleeve.
The utility model is fixed on middle stationary positioned plug on holder and directly is connected with machine tool, guarantees and the machine tool one, has guaranteed that positioning datum is constant, thereby has guaranteed that converted products axially changes less than 0.05mm; And gripping sleeve internal diameter and stationary positioned plug external diameter precision-fit have guaranteed that the converted products circular runout is less than 0.05mm.And draw the clamping force that rises to realize effective communication by adapter sleeve, transmission screw, gripping sleeve and the wedging of end cap inclined-plane.
