Abstract
The invention relates to an axial location tensioning clamping device. An end cover is fixed 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 location core rod is fixed in the fixed seat; an annular rib is arranged on an excircle of a middle section of the fixed location core rod; the annular rib of the fixed location core rod and a clamping sleeve are fixed into a whole by a driving screw; an excircle of a front section rod body of the annular rib of the fixed location core rod is matched with an inner circle of the clamping sleeve; an outer circular conical surface is arranged at the front end of the clamping sleeve; a circular conical bottom surface of the outer circular conical surface is positioned on the front end face of the clamping sleeve; an inner circular conical surface is arranged at the front end of the end cover; a circular conical bottom surface of the inner circular conical surface is positioned on the front end face of the end cover; and the outer circular conical surface on the clamping sleeve is matched with the inner circular conical surface on the end cover. The device can ensure that axial variation of a machined product is less than 0.05mm, and tensioning clamping force achieves effective transmission through the connecting sleeve, the driving screw, the clamping sleeve and the end cover via wedging of the inner circular conical surface and the outer circular conical surface.
Description
Technical field
The present invention relates to a kind of converted products that mainly is used in 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 axial location of domestic widespread usage 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 processed sometimes reaches more than the 0.15mm, axially change need the redesign clamp mechanism less than 0.05mm in order to guarantee product processed.
Summary of the invention
The objective of the invention 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.
According to technical scheme provided by the invention, described axial location is drawn the clamping device that rises, comprise adapter sleeve, holder, end cap and gripping sleeve, front end face at holder fixedly has end cap, rear end face at holder is provided with adapter sleeve, the stationary positioned plug is fixedly arranged in holder, 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 interior 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 fixedly has reinforcing sleeve.
The present invention is fixed on the center fixed location mandril on holder and directly is connected with machine tool, guarantees and the machine tool one, has guaranteed that the location benchmark 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 effectively transmitting by adapter sleeve, transmission screw, gripping sleeve and the wedging of end cap inclined-plane.
