Description
Technical field
The utility model relates to a kind of tailstock mandrel taper hole autogenous grinding device, belongs to machine tool auxiliary equipment technical field.
Background technology
At present, machine industry horizontal lathe tailstock sleeve mandrel taper hole is to form after barrel of tail stock, bearing, mandrel assembling by three part parts, conventionally the precision of high precision machine tool tailstock instrument taper hole is 0.005mm, so just require barrel of tail stock bearing mounting hole to have very high circularity and axiality precision prescribed, bearing has high accuracy class, mandrel bearing is installed the diameter of axle high circularity and axiality precision prescribed, and mandrel instrument taper hole has high total run-out requirement to the diameter of axle simultaneously.Because barrel of tail stock, bearing, mandrel occur trueness error in manufacture, process, will in assembling, produce larger error, need to improve the precision of manufacturing and processing.
Summary of the invention
In order to overcome above-mentioned technical deficiency, the utility model provides a kind of tailstock mandrel taper hole autogenous grinding device, this tailstock mandrel taper hole autogenous grinding device can reduce the accuracy of manufacture of barrel of tail stock, mandrel and the assembly difficulty of parts, mandrel taper hole adds fine finishining without machine, after barrel of tail stock is installed, on common grinding machine of universal or lathe, carry out autogenous grinding and eliminate rigging error.
The utility model solves the technical scheme that its technical problem adopts: its structure of tailstock mandrel taper hole autogenous grinding device is: power transmission shaft is a microscler pole axle, its front end is fixed with terminal pad, terminal pad circumferencial direction is laid with the hole of several construction bolts, power transmission shaft rear end is provided with two multidiameters, secondary multidiameter is provided with screw thread, on its screw thread, be equipped with locking nut, one-level multidiameter is provided with screw thread, universal socket is threaded, universal socket universal-joint, the other end of universal joint connects another universal socket, universal socket connection for transmission dish, on power transmission shaft, slip cap has positioning disk, the rear side of positioning disk is equipped with bearing, bearing rear end is equipped with adjustment sleeve.
The beneficial effects of the utility model are: can reduce the precision in processing, assembling by autogenous grinding device grinding taper hole, reduce the cost of processing and assembling; Ensure that beating of sleeve part core component instrument taper hole reaches in 0.003mm.
