Description
Technical field
But the utility model relates to a kind of tapering axle of axial location.
Background technology
Batch machining part on numerically controlled lathe, reliable and stable axial location benchmark must be arranged, but some part will utilize taper hole to position processing, because certainly exist aperture error after the taper hole processing, when with general tapering axle location, workpiece will produce axial displacement, makes troubles not only for the numerically controlled lathe tool setting, and can not guarantee the axial dimension requirement of workpiece.Therefore utilize taper hole to position and add man-hour, must solve this crucial difficult problem.
In small batch was produced, people adopted the part of engine lathe processing and utilization taper hole location usually at present, can't utilize advanced numerically controlled processing equipment, and working (machining) efficiency is low, the machining accuracy instability.
The utility model content
But technical problem to be solved in the utility model provides a kind of tapering axle of axial location, and to solve at present in small batch is produced, working (machining) efficiency is low, problems such as machining accuracy instability.
Technical problem to be solved in the utility model can be achieved through the following technical solutions:
But a kind of tapering axle of axial location comprises chuck, it is characterized in that, also comprises a taper hole positioner, and this taper hole positioner comprises:
One positioning sleeve, this positioning sleeve are clipped on the outside chuck;
One bolt, this bolt is with the coaxial setting of described positioning sleeve and be fixed in the described positioning sleeve, and the on-fixed end of described bolt has an external screw thread;
One spring, this spring housing are positioned at described positioning sleeve inside on described bolt;
One location axle, this apotting spindle are enclosed within on the described bolt and are partially embedded in the described positioning sleeve and from a side pressure of described spring compels spring; This apotting spindle stretches out the outer part of positioning sleeve and has taper seat, to realize the tapering location of workpiece;
One nut, this nut are spun on the external screw thread of described bolt, with described positioning core axle workpiece are implemented axial location.
After adopting above technical scheme, satisfied the positioning requirements of processing and utilization taper hole locating element on numerically controlled lathe.Realize the digital control processing of taper hole locating element, also improved working (machining) efficiency and the precision of utilizing taper hole location processing parts.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
But a kind of tapering axle of axial location comprises chuck, also comprises a taper hole positioner, and this taper hole is positioned with a positioning sleeve 1, and this positioning sleeve 1 is clipped on the outside chuck; Positioning sleeve 1 has a hole for the cylinder of bottom 11 is arranged on this bottom 11, this hole base portion is welded with a bolt 4 coaxial with positioning sleeve 1, and the diameter of the size in this hole and bolt 4 about equally.The internal diameter of positioning sleeve 1, is enclosed within on this bolt 4 for spring 2 and apotting spindle 3 so between positioning sleeve 1 and bolt 4 space is arranged greater than the diameter of bolt 4, is installed in this space.Apotting spindle 3 parts 32 are embedded in the described positioning sleeve 1, and compel spring 2 from a side pressure of described spring 2.Spring 2 the effect here is when apotting spindle 3 and workpiece 5 are pushed to the base portion of positioning sleeve 1 by nut 7, apply a reverse power can for location axle 4, so just can be with apotting spindle 3 and workpiece 5 clampings, so that workpiece 5 is carried out axial location.Apotting spindle 3 stretches out positioning sleeve 1 outer another part 31 and has taper seat, to realize the tapering location of workpiece; On-fixed end at bolt 4 also is provided with an external screw thread, so that nut 7 is spun on the external screw thread of described bolt 4, with described apotting spindle 3 workpiece 5 is implemented axial location.
This tapering axle also is with a packing ring 6 on bolt 4, between nut 7 and workpiece 5, can make nut 7 contact more abundant with workpiece 5.
During use, earlier positioning sleeve 1 is clipped in centering on the chuck.On bolt 4, overlap upper spring 2, apotting spindle 3, workpiece 5, packing ring 6 and nut 7 then successively.Rotating nut 7 can extruded gasket 6, the taper seat 31 of the end face 51 of workpiece 5 and apotting spindle 3 is relatively moved be close to until the zero clearance; Be rotated further nut 7,, apotting spindle 3 and bolt 4 produced relatively move, be close to the end face 12 of positioning sleeve 1, the clamping location of finishing workpiece until workpiece 5 end faces 52 by workpiece 5, apotting spindle 3, compression spring 2.
Because the locating surface 12 of positioning sleeve 1 all was changeless after the each clamping of this axle was finished, so the axial locating surface of workpiece 5 also guarantees to immobilize, and satisfied the positioning requirements of processing parts on numerically controlled lathe.
More than show and described basic principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; the utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
