Abstract
The utility model discloses a cushion cover type elastic center device for conical surface grinding of a crankshaft, relating to a center structure for machine tool processing. The cushion cover type elastic center device comprises a center shaft and a center body, wherein the center body is composed of a center sleeve, a center shaft, a sealing sleeve and a rotating sleeve. One end of a compression spring in a tail hole of the center sleeve is sheathed in a bind hole of the lower shaft of the center shaft, and the other end is sheathed on a tail step shaft. The external circle of the center shaft is provided with an axial long slot, and a rotation-stopping screw is sheathed in the axial long slot. The sealing sleeve is in a hollow step shaft shape, and the lower seam of the sealing sleeve is sheathed in the inner hole seam of the upper end part of the center sleeve and then is fixed through a bolt. The external circle of the upper shaft body of the sealing sleeve is fixedly sheathed a ring dish and a radial bearing, and an axial bearing is sheathed above the external circle. The upper shaft of the center shaft penetrates through the shaft shoulder of the central hole of the sealing sleeve in a movable fit mode to be contacted with the sealing sleeve, and the inner circle of the rotating sleeve is sheathed on the two bearings. The cone body of the upper end part of the center shaft penetrates through the upper end hole of the rotating sleeve to be positioned in a cushion cover, and the two end surfaces of the shaft-sleeve type cushion cover are butted between the rotating sleeve and a workpiece. The cushion cover type elastic center device has the advantage that the axis position of the workpiece is ensured as the center shaft elastically supports the workpiece.
Description
Technical field:
The utility model relates to the machine tooling top tip structure, particularly a kind of bent axle conical surface grinding cushion cover formula centre with endlong movement device.
Background technology:
Bent axle adds to be needed the conical surface on the standard shaft is carried out grinding man-hour, and for preventing circular runout, existing cylindrical grinder is to the general stationary center that uses of bent axle processing, and promptly workpiece changes tail spindle does not change.This false ceiling is easy to wear, top conical surface diameter dimension can change, also there is error in workpiece center hole diameter, top and center hole change in size can guarantee that still workpiece clamps back workpiece axial line registration, but can make workpiece produce microdisplacement at direction of axis line, this displacement is no problem for the isometrical axle of grinding, but will produce error to conical surface grinding.Because bistrique keeps the depth of cut by the traverse feed position of original location, then will change with vertex of a cone size at the bottom of the awl of grinding, workpiece accuracy can not get guaranteeing.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned defective, and a kind of bent axle conical surface grinding cushion cover formula centre with endlong movement device is provided.
Scheme of the present utility model is: comprise tail spindle, it is characterized in that: device is made up of top body, cushion cover, and top body is made up of center sleeve, tail spindle, capping cover, turning set; Center sleeve is a cavity tail cone of a sleeve body disjunctor body, and the tail spindle bottom axis body that is step axle shape is enclosed within the center sleeve medium pore movingly; Compression spring one end is linked in the tail spindle lower shaft blind hole, being compression type with the shaft shoulder on the axis body of fit double end step axle top in the other end stomidium contacts, double end step axle bottom axis body is enclosed within the screwed hole of center sleeve tail cone body end movingly, and this screwed hole hypomere is sheathed with the adjusting bolt; The tail spindle cylindrical offers an axial elongated slot, and a rotation stopping screw is twisted and is combined in the center sleeve radial screw bore, and its end is stretched in the axial elongated slot of tail spindle movingly; The capping cover is hollow step axle shape, after capping cover bottom seam is linked in the endoporus seam of center sleeve upper end, implementing both with the screw on the capping cover shaft shoulder fixes, capping puts an axis body cylindrical fixed cover unification circle ring disk, a circle ring disk cylindrical fixed cover unification journal bearing, a cover unification cod on the circle ring disk top capping cover axis body, the tail spindle upper axis is passed capping cover medium pore movingly, and its shaft shoulder is compression type with capping cover lower surface and contacts; Turning set is three grades of stepped hole sleeve-like, after its underpart stepped hole is linked on the capping cover journal bearing cylindrical, hypomere circle inwall and capping cover shaft shoulder cylindrical are state movingly, turning set upper step hole inwall and capping are overlapped on the axial bearing trim ring cylindrical and are stationary fit and fix, and tail spindle upper end cone is passed the turning set upper end hole; Cushion cover is a sleeve-like, and circular diameter is greater than treating top bent axle lower end axis body external diameter in the cushion cover, and cushion cover length is greater than treating top bent axle lower end axis body length, and the cushion cover both ends of the surface are passive respectively to be fitted on turning set upper surface, the bent axle lower end shaft shoulder lower surface.
Advantage of the present utility model is: the cushion cover position has guaranteed to produce the axial co-located of each bent axle in batches, and tail spindle elasticity heads on workpiece and guaranteed workpiece axle center line position.
Description of drawings:
Accompanying drawing is the utility model structural representation.
