Description
Technical field
The present invention is novel to be related to the device of a kind of Internal hole positioning workpiece and swelling.
Background technique
At present when machining disk cover parts, such as with oil cylinder or guide sleeve Internal hole positioning turning and end face.It is inner
The device that hole positions and clamps, is usually tensioned workpiece with inner hole chuck outward, and this mode is easy to make inner hole when being tensioned workpiece
Surface is injured, and easy clamping deformation cannot use some this modes of the workpiece for having high request completely.In being there are also a kind of mode
Mandrel is through on the inner hole of workpiece, is then clamped to an axial force, and this device mode has the following disadvantages: first is that clamping work
When part, there is a clamping plate to be pressed in the end face of workpiece, be capable of processing end face not, can only processing excircles, be restricted the range of work,
Second is that being not suitable for positive and negative rotation rotational workpieces, it is easy to loosen workpiece.Third is that batch production each workpiece of clamping will remove folder
Plate influences production efficiency.
Summary of the invention
The purpose of the present invention: designing the device of a kind of Internal hole positioning workpiece and swelling, when clamping workpiece simultaneously with Internal hole positioning
The inner surface of workpiece is not hurt in swelling, convenient for mounting and clamping, can be carried out cutting in the outer round surface of workpiece and end face after clamping and be added
Work greatly increases production efficiency, and can guarantee the precision of product again.
The technical solution adopted by the present invention to solve the technical problems is:
A kind of Internal hole positioning workpiece and the device of swelling include: central axis 1, lathe clamping position 2, axially position step 3, in workpiece
Hole positioning cylindrical surface 4, workpiece 5, swelling rubber sleeve 6, activity orientation clamping sleeve 7, clamp nut 8 and centre bore 9.
Lathe clamping position 2, axially position step 3, inner hole of workpiece positioning cylindrical surface 4 and center are provided on central axis 1
Hole 9.
In 7 inner hole of workpiece positioning cylindrical surface 4 of activity orientation clamping sleeve, with 4 shape of inner hole of workpiece positioning cylindrical surface on central axis 1
Make the Internal hole positioning of workpiece 5 at two-point locating, workpiece 5 is axially positioned on axially position step 3.
On lathe chuck, centre bore 9 is withstood on tailstock tool 2 clamping of lathe clamping position on central axis 1.
The inner hole of activity orientation clamping sleeve 7 and the mandrel of central axis 1 are slidably matched using accurate, can axis along central axis 1
To sliding, activity orientation clamping sleeve 7 and central axis 1 are clipped in the middle swelling rubber sleeve 6 along axial direction, and clamp nut 8 passes through center
Screw thread on axis is pressed on the end face of activity orientation clamping sleeve 7.
When tightening clamp nut 8, pressure is passed to swelling rubber sleeve 6 by activity orientation clamping sleeve 7, makes swelling rubber sleeve 6
It is radially deformed, makes workpiece 5 by swelling, achieve the purpose that positioning and clamp, after tightening, swelling rubber sleeve 6 gives compression spiral shell
Mother 8 produces an axial thrust, loosen clamp nut 8 will not, when unscrewing clamp nut 8, when swelling rubber sleeve 6 is compressed
The energy of storage releases, and pushes activity orientation clamping sleeve 7 to be returned to original position, can carry out the clamping of next workpiece.
The beneficial effects of the present invention are:
Do not hurt the inner surface of workpiece when clamping, it is convenient for mounting and clamping, it can be cut in the outer round surface of workpiece and end face after clamping
Processing is cut, production efficiency is greatly increased, is suitble to produce in enormous quantities.
Repetitive positioning accuracy is high, will not loosen after clamping, be not easy clamping deformation, reliable in quality.
It is widely used, it can be used for oil cylinder guide sleeve, piston and gear teeth positioning and clamping etc..
The present invention is described in detail with reference to the accompanying drawings of the specification.
