Description
Technical field
This application involves Computerized Numerical Control processing technology field, a kind of particularly NC machining parts close angle clamping device.
Background technology
In NC milling, the main machine direction of mounting means and machine tool chief axis generally according to part will be processed
Mode is divided into vertical processing and horizontal processing.Under vertical processing method, part is is horizontally mounted, the main processing side of machine tool chief axis
To for vertical direction, as shown in Figure 1；Under horizontal processing method, part is vertically-mounted, and the main machine direction of machine tool chief axis is
Horizontal direction, as shown in Figure 2.
But stood in the turntable type being widely used at present in sleeping conversion Five-axis NC Machining Center equipment, no matter vertical processing side
Formula or horizontal processing method, all have some limitations, and limit the range of work of part, affect the hair of equipment effectiveness
It waves.
Under traditional vertical processing method, since turntable type stands the machine tool structure limitation of sleeping conversion Five-axis NC Machining Center,
The Y-direction stroke of lathe is generally relatively small, therefore, limits the width range of work of part, the slightly larger part of width adds
Man-hour can not process it is easy to appear Y-direction overtravel.
Under horizontal processing method, since the main shaft pivot angle that turntable type founds sleeping conversion Five-axis NC Machining Center is general maximum to water
Square to, i.e., point of a knife will not face upward, therefore, when part appearance close corner structure as shown in the figure when, will be unable to complete by five axis pivot angles
Into corner structure processing is closed, the range of work of five axis pivot angles is limited.Particularly in aerospace component, it is largely to deposit to close corner structure
Structure, therefore, equipment can the range of work be very limited.
The content of the invention
The purpose of the application be to design it is a kind of can extend turntable type stand the sleeping conversion Five-axis NC Machining Center Y-direction range of work with
And five the axis pivot angle range of work close angle numerical-control processing method and clamping device.
By this processing method and clamping device, solve turntable type and found sleeping conversion Five-axis NC Machining Center in vertical processing
Existing Y-direction stroke deficiency and the five axis pivot angles processing stroke deficiency problem under horizontal processing method, greatly expand under mode
Equipment can the range of work.
A kind of NC machining parts close the clamping device at angle, and the cross section of the clamping device is in a rectangular trapezoid, comprising mutual
Parallel top plane and baseplane and a tapered plane, tapered plane and vertical direction institute is angled to be more than maximum on part and closes
Angle angle, on tapered plane distribution there are two location hole and several bolts hole, in the top plane there are one vertical benchmark
Hole, side on the basis of a side adjacent with tapered plane of baseplane.
In use, clamping device is placed on the platform of numerically-controlled machine tool, baseplane is bonded with platform of machine tool, and true edge is parallel
In lathe X-direction, by part location and installation on the tapered plane of clamping device；Utilize datum hole on clamping device and location hole
Relativeness establishes Cutter coordinate system, and the origin of Cutter coordinate system is overlapped with the center of datum hole；By in above-mentioned machining coordinate
The lower nc program established of system completes the five axis pivot angles processing of part.
The advantages of the application, is that it is existing under vertical processing method to found sleeping conversion Five-axis NC Machining Center for turntable type
Y-direction stroke deficiency by the way that part wide-angle tilt is installed, substantially reduces the Y-direction stroke needed for part processing, so that wide
Larger part is spent to be processed.Meanwhile under horizontal processing method five axis pivot angles process stroke deficiency problem, pass through by
The inclination installation of part compensates under horizontal processing method five axis pivot angles processing stroke deficiency, makes originally to exceed five axis pivot angles and adds
The structure of work scope is in can be within the range of work, and greatly expand equipment can the range of work.
