A bar that can be recycled successfully is extracted in the workpiece of work, iron filings when making to be processed with drill bit originally become to recycle
Finished product.Common trepanning tool generally have " flat tooth shape trepanning tool " and two pointed tooths, two flat tooths two kinds of " pointed tooth trepanning tool ",
Existing two pointed tooth relief angles of pointed tooth trepanning tool are usually to be processed with dividing head change gear mode, and hand processing efficiency is low and precision
It is not high, it is necessary to be improved.
In view of the above shortcomings, the designer, is actively subject to research and innovation, to found a kind of pointed tooth of new structure
The processing unit (plant) of trepanning tool makes it with more the utility value in industry.
Invention content：
The purpose of the present invention aims to solve the problem that problem of the existing technology, provides a kind of high precision machining, efficient point
The processing unit (plant) of tooth trepanning tool.
The present invention relates to the processing unit (plant)s of pointed tooth trepanning tool, including dividing head, further include and are inserted in the dividing head taper hole
Taper shaft, one end of the taper shaft is equipped with external splines；Cam mould plate, the cam mould are arranged on the external splines
Endoporus is offered on plate, the endoporus is equipped with the internal spline coordinated with the external splines；The cam mould plate has endoporus
One end is connected with cam motherboard by pattern spring, and the other end is fixedly installed workpiece assembling seat；The cam motherboard and cam
The spur tooth of mutual cooperation is respectively equipped on master plate；The cam motherboard is fixedly mounted on pedestal, the workpiece assembling seat
On be provided with trepanning tool.
The middle of the base is equipped with through-hole as a preferred embodiment of the above solution, and the taper shaft passes through the through-hole.
The cam motherboard is not contacted with taper shaft as a preferred embodiment of the above solution,.
The trepanning tool, workpiece assembling seat, cam mould plate, cam motherboard, pedestal and cone as a preferred embodiment of the above solution,
The center of degree axis all passes through the axle center of dividing head.
The workpiece assembling seat is mounted on by trip bolt on cam mould plate end face as a preferred embodiment of the above solution,.
The trepanning tool is mounted on by screw on workpiece assembling seat as a preferred embodiment of the above solution,.
According to the above aspect of the present invention, the present invention has at least the following advantages：The present invention by having the taper of external splines at one end
Cam mould plate, cam mould flat spring connection cam motherboard are arranged on axis, cam mould plate can be rotated and be passed through with taper shaft
Spring is close to cam motherboard and is moved axially back and forth, and by the effect of the pointed tooth of mutual cooperation, cam mould strip moves jacking
Knife moves to form pointed tooth relief angle track, so as to process pointed tooth relief angle；The present invention is convex using plane for trepanning tool processing key
Wheel, pattern process principle, without on dividing head change gear it is hand walk it is differential processing spiral relief angle, be trepanning tool pointed tooth tool clearance
New process, new tool have been reformed in processing, and efficiency and quality are obtained for raising.
Above description is only the general introduction of technical solution of the present invention, in order to better understand the technological means of the present invention,
And can be implemented in accordance with the contents of the specification, below with presently preferred embodiments of the present invention and after attached drawing is coordinated to be described in detail such as.
Description of the drawings：
The following drawings are only intended to schematically illustrate and explain the present invention, not delimit the scope of the invention.Wherein：
