The utility model is the problem such as low and operating efficiency for the machining accuracy that solves above-mentioned axle and exist, thereby a kind of novel elastic axle is provided.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of novel elastic axle, described elastic spindle comprises mounting flange, elasticity apotting spindle, spindle taper and location-plate, described ring flange and machine tool chief axis are flexibly connected, described elasticity apotting spindle is arranged on ring flange, be provided with the taper hole that tapering matches with the spindle taper tapering on its small end, described spindle taper is placed in the taper hole small end, and both cooperation taperings are greater than angle of friction between the two; Described location-plate is arranged on the elasticity apotting spindle.
Further, the one side of described mounting flange is taper hole, and another side is recessed seam.
Further, described elasticity apotting spindle integral body is multistage frustum cone structure, and its large end and mounting flange join, and are provided with the taper hole matched with spindle taper in small end, and described small end evenly is provided with 6 openings along the taper hole circumferencial direction.
Further, the bottom of described taper hole is provided with a cannelure.
Further, the root of described small end lateral surface is provided with a protruding shoulder, and described protruding shoulder matches with location-plate.
By technique scheme, the beneficial effects of the utility model are:
(1) axle is convenient flexible in use.
(2) improved the machining accuracy of workpiece.
(3) improved operating efficiency.
(4) reduced cost.
The accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, below will the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
The structural representation that Fig. 1 is existing cylindrical mandrel;
The structural representation that Fig. 2 is existing circular cone axle;
Fig. 3 is cutaway view of the present utility model;
The right view of the elasticity apotting spindle that Fig. 4 provides for the utility model;
The cutaway view of the elasticity apotting spindle that Fig. 5 provides for the 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.
Referring to Fig. 3, a kind of novel elastic axle that the utility model provides mainly comprises mounting flange 100, elasticity apotting spindle 200, spindle taper 300 and location-plate 400.
The first joint face 110 is taper hole, and it can be flexibly connected by attachment screw 111 and machine tool chief axis.
The second joint face 120 is a recessed seam, and it closely is connected with elasticity apotting spindle 200 by attachment screw 121.
Elasticity apotting spindle 200 just can be arranged on machine tool chief axis by ring flange 100 is dismountable like this.
Elasticity apotting spindle 200, be the core component of this device, and its integral body is that a multistage frustum cone structure comprises the large end 210 of bottom and the small end 220 at top.
One taper hole 221 identical with the tapering of spindle taper 300 is set on small end 220, and taper hole 221 is used for settling spindle taper 300.
Referring to Fig. 4 and Fig. 5, in taper hole 221 bottoms, one cannelure 222 is set, like this, it both can be used as the cutter groove, can improve again the spring function that the workpiece position is installed.
In order further to improve elasticity, on small end 220, along taper hole 221 circumferencial directions, 6 openings 223 have evenly been processed.
Root in small end 220 outsides, also be provided with the shoulder 224 of a projection, and this shoulder 224 matches with location-plate 400.
Location-plate 400 in this device is arranged on by attachment screw 226 on the upper surface of the large end in bottom of elasticity apotting spindle 200, and matches with the shoulder 224 of small end 220 outside roots.By being connected of location-plate 400 and shoulder 224, both improve the workpiece positioning precision like this, do not affected again the effect of small end strain stretching workpiece.
Simultaneously, the utility model, also in the centre of elasticity apotting spindle 200, arranges a screwed hole 230, and it is to match with the screw thread on spindle taper 300.
Spindle taper 300, by taper hole 221, with elasticity apotting spindle 200, be connected, also be provided with hold-down bolt 310 on spindle taper 300, hold-down bolt 310 matches with the screwed hole 230 of elasticity apotting spindle 200, so just can adjust the distance between spindle taper 300 and elasticity apotting spindle 200 by regulating hold-down bolt 310, thereby change elasticity.
Make like this utility model very convenient in use, only need to get final product by rotating hold-down bolt 310.
When connecting, spindle taper 300 is identical with the tapering of the mating surface of elasticity apotting spindle 200, and tapering must be greater than the angle of friction between spindle taper 300 and elasticity apotting spindle 200, guarantee is after hold-down bolt unclamps like this, under the screen resilience effect of elasticity apotting spindle, spindle taper is released, recover original size, be conducive to the installation of next workpiece.
Below concrete use procedure of the present utility model:
After workpiece is in place, rotate hold-down bolt 310, spindle taper 300 is moved inwards, force elasticity apotting spindle 200 radial dimensions to become large, thereby by the workpiece stretching, after the workpiece process finishing, rotate round about hold-down bolt 310, spindle taper 300 outwards moves under the 200 restoring force effects of elasticity apotting spindle, the size decreases of elasticity apotting spindle 200, then take out workpiece.So greatly improve the machining accuracy of workpiece, improved operating efficiency, reduced cost.
Above demonstration and described basic principle of the present utility model and 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 in above-described embodiment and specification, describes just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, 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.
