（≤0.05mm）, rigidity is weak and the features such as easily deformation, causes the concern and attention of mechanical processing industry.Due to shape of product
And the difference of processing method, positioning clamping mode also differ greatly, the product processed is difficult to meet product design requirement.
Utility model content
In order to solve the above-mentioned technical problem, the utility model provides a kind of simple in structure, and it is safe and reliable fixed to realize
Position clamps workpiece, so as to which the taper for meeting the requirement on machining accuracy of thin-wall part rises spring clamping device.
The technical solution adopted in the utility model is：A kind of taper rises spring positioning clamping device, including axis, fixed cone,
Spring, taper rise spring, activity cone and mandrel；Fixed cone is fixedly mounted on axis, and the activity cone is sleeved on axis,
Spring is equipped between activity cone and fixed centrum, spring pocket is on axis；The mandrel is inserted into the centre bore of axis one end
It is interior, pass through removable pin and axis connection；The exposed junction of mandrel is equipped with flange, activity cone can be positioned, movable centrum is equipped with
The material returned is followed closely；Rise one end of spring of the taper is positioned on the conical surface of fixed cone, and the other end is positioned over the conical surface of activity cone
On.
Above-mentioned taper rises in spring clamping device, and the pin hole of the removable pin on the axis is long straight hole, the length of long straight hole
Direction is spent to set along the axis direction of axis；Nut is equipped on axis at the pin hole of removable pin；Nut be equipped with cotter way, the two of removable pin
End is arranged in cotter way.
Above-mentioned taper rises in spring clamping device, is equipped with adjusting pad between the spring and fixed cone, adjusts cushion cover
On axis.
Above-mentioned taper rises in spring clamping device, the taper rise spring include cylindrical section and conical section, cylindrical section end
Inner circle cone-apex angle for α, the inner circle cone-apex angle of conical section end is β, α ≠ β, and the line of rabbet joint of cylindrical section and conical section mutually staggers.
Above-mentioned taper rises in spring clamping device, and the inner end of activity cone is cylindrical surface, rises with taper in the middle part of spring between endoporus
Gap coordinates.
Compared with prior art, the beneficial effects of the utility model are：
1st, the utility model is simple in structure, and taper rises by spring using Bidirectional clamping mode, overcomes since machining stress makes
The deformation that product occurs, ensure that the Wall-Thickness Difference of institute's converted products full section is uniform, has many advantages, such as easy to operate, safe and reliable.
2nd, the characteristics of easily being deformed again according to cylindrical shape thin-wall part poor rigidity, the utility model are risen spring cylindrical end using taper
As master positioning, taper rises the rigid strong position of conical surface end supporting workpiece of spring, and taper is made to rise the uniform tensioner workpiece inner wall of spring；It is right
In cylinder short taper profile thin-wall part, its rigidity is added, reduces the cutting vibration in process, improves machining accuracy.
