Description
Technical field
The utility model relates to machinery manufacturing technology field, is a kind of high precision elastic location cylindrical grinding mandrel specifically, is used to process the demanding sleeve workpiece of various coaxial accuracies.
Background technology
Sleeve workpiece is prone to produce distortion, vibrations, the not high bad phenomenon of precision in process, and in the prior art, the cylindrical grinding operation is utilized rigid central spindle or the processing of plastics mandrel, and its processing method can not guarantee coaxial accuracy, has satisfied not designing requirement.Utilize rigid central spindle processing, the gap is big between mandrel and the workpiece, has guaranteed not the axiality requirement of workpiece, and the gap is little, and the workpiece dress is not entered; Utilize plastics mandrel processing, the frock making difficulty is too big, and cost is high, and mandrel and workpiece endoporus can not guarantee to closely cooperate fully.
Summary of the invention
The purpose of the utility model provides a kind of high precision elastic location cylindrical grinding mandrel, to solve above-mentioned existing in prior technology problem.This elasticity location cylindrical grinding mandrel high efficiency, accurate positioning, machining accuracy height, easy to use.
The technical scheme that the utility model adopted is that high precision elastic location cylindrical grinding mandrel is blocked up by hollow tapered sleeve, spring housing, opening pressing plate, clamp nut, locknut, a left side and right blocking up constitutes; Hollow tapered sleeve is that the left side has the hollow shaft that the shaft shoulder, cylindrical have tapered section, shaft shoulder cylindrical and locknut threaded engagement, and the shaft shoulder right side is the workpiece locating surface; A left side is stifled to be welded in the rim of the mouth of hollow tapered sleeve left end, the right stifled right-hand member that is welded on hollow tapered sleeve endoporus, hollow tapered sleeve, the left stifled and right stifled rigid core axis body of forming; The spring housing endoporus is identical with hollow tapered sleeve outer cone body section tapering, is enclosed within on the cylindrical cone segments; Clamp nut and right stifled right-hand member threaded engagement, opening pressing plate insert on the right stifled axle, between spring housing and clamp nut.
The beneficial effect of the utility model is, utilizes the expanding force of spring housing to eliminate the gap between mandrel and the workpiece, thereby guarantees the axiality requirement of workpiece, improves machining accuracy, and is installed conveniently, and is simple to operate.
Description of drawings

Fig. 2: be the sketch map after the utility model installs workpiece additional.
The specific embodiment
Among the figure: 1, hollow tapered sleeve, 2, spring housing, 3, the opening pressing plate, 4, clamp nut, 5, locknut, 6, workpiece, 7, a left side is stifled, 8, right stifled.
Shown in Fig. 1～2, high precision elastic location cylindrical grinding mandrel is made up of hollow tapered sleeve 1, spring housing 2, opening pressing plate 3, clamp nut 4, locknut 5, a left side stifled 7 and right stifled 8; Hollow tapered sleeve 1 is that the left side has the hollow shaft that the shaft shoulder, cylindrical have tapered section, shaft shoulder cylindrical and locknut 5 threaded engagement, and the shaft shoulder right side is the workpiece locating surface; A left side stifled 7 is welded in the rim of the mouth of hollow tapered sleeve 1 left end, and right stifled 8 are welded on the right-hand member of hollow tapered sleeve 1 endoporus, and hollow tapered sleeve 1, left stifled 7 and right stifled 8 is formed the rigid core axis body; Spring housing 2 endoporus are identical with hollow tapered sleeve 1 cylindrical cone segments tapering, are enclosed within on the cylindrical cone segments; Clamp nut 4 cooperates with right stifled 8 right-hand member external screw thread, and opening pressing plate 3 inserts on right stifled 8, between spring housing 2 and clamp nut 4.
The tapering of hollow tapered sleeve (1) cylindrical cone segments and spring housing (2) endoporus is 1: 5～and 1: 7.
Workpiece adds man-hour, on the rigid core axis body, loads onto spring housing 2, and workpiece 6 is contained on the spring housing 2; Insert opening pressing plate 3, rotate clamp nut 4, make opening pressing plate 3 promote workpiece 6 axially-movables; Be close to the locating surface of rigidity axle axon shoulder, when clamp nut 4 changes motionless, spring housing 2 spreadings; Closely cooperate with workpiece 6, the centre bore of high precision elastic cylindrical grinding mandrel with left and right sides plug is positioned on the main shaft of outer first grinding machine, carry out cylindrical processing; After workpiece processes, unclamp clamp nut 4, extract opening pressing plate 3, rotation locknut 5 ejects workpiece.
This cylindrical grinding mandrel clamping device can be according to Workpiece length a plurality of parts that once are installed.
