Description
Technical field
The utility model belongs to the special type knife technical field, more particularly relates to the improvement of endoporus annular groove special turning cutting tool.
Background technology
The endoporus annular groove is usually used in the occasions such as installation of circlip for hole, is one of machining element of machine components.The traditional diamond-making technique of endoporus annular groove is the Vehicle Processing on lathe.Add and want first drill centers man-hour, repeatedly tool setting then, repeatedly turning, repeatedly measurement.Therefore, this processing method efficient is very low, time-consuming, and production cost is also high, and each endoporus annular groove must repeat above-mentioned process one by one, also is like this even produce in enormous quantities.In addition, this processing method can not be processed on better simply machining tools such as drilling machine.
The purpose of this utility model, just be to overcome above-mentioned shortcoming and defect, a kind of repeatedly tool setting, repeatedly turning are provided, repeatedly measure, the working (machining) efficiency height, crudy is good, and can guarantee the uniformity of workpiece, and production cost is low, can on better simply machining tools such as drilling machine, process the endoporus annular groove special turning cutting tool that is particularly suitable for producing in enormous quantities.
Summary of the invention
In order to achieve the above object, the utility model comprises the main shaft of anterior band eccentric inner hole rear portion band taper shank at least, be sleeved in the eccentric inner hole of main shaft and its side has the knife bar that its front portion of helicla flute has transverse holes and center screw, the screw of processing on the eccentric inner hole sidewall, be installed in the steel ball in the helicla flute of this screw and knife bar, be installed in the holding screw of in the screw steel ball being located, be sleeved in the eccentric inner hole and be positioned at the stage clip of knife bar back, be installed in the lathe tool in the transverse holes of knife bar front portion, be installed in holding screw and nut in the center screw of knife bar front end.The front end of lathe tool is being fixed the turning cutter head.Screw is positioned at the thickest place of eccentric inner hole and main shaft lateral surface.
Earlier taper shank of the present utility model is inserted in the main shaft of drilling machine, turn down the main shaft of drilling machine then, the utility model is inserted in the endoporus of desiring processing work.Holding screw in the utility model front end center screw is leaned on the workbench of drilling machine, adjust the radius that stretches out of the position of workpiece and lathe tool, make it just to be slightly less than the radius of workpiece endoporus.The holding screw of tightening subsequently in the center screw is good with the lathe tool clamping, and workpiece is fixed on the workbench, just can begin processing.
Add man-hour, start drilling machine earlier, turn down the main shaft of drilling machine, the utility model is inserted in the endoporus of desiring processing work.When the holding screw in the screw of center leans on the workbench at drilling machine, lathe tool stretch out the radius that radius just is slightly less than the workpiece endoporus, steel ball is positioned at knife bar spiral fluted original position.Continue to turn down the main shaft of drilling machine, under the pressure of drill press spindle, rotate the feeding that moves up along its helicla flute with respect to drilling machine and main shaft of the present utility model while knife bar just can be guiding with the steel ball.Because of knife bar is installed in the eccentric inner hole of main shaft, an eccentric throw is arranged between knife bar and the main shaft again, along with the relative rotation of the two, lathe tool is stretched apart from also just strengthening gradually with respect to the spindle axis line, and the feed in the workpiece endoporus is also just increasing.Meanwhile, lathe tool is just processed the turning of endoporus annular groove along with the main shaft revolution of drilling machine.When knife bar is fed to the spiral fluted end, lathe tool is stretched apart from maximum with respect to the spindle axis line, and its feed in the workpiece endoporus is also just maximum, and the endoporus annular groove just machines.Lift drill press spindle then, under the tension force effect of stage clip, knife bar just can be that guiding retreats along its helicla flute and to reset with the steel ball, and lathe tool is stretched apart from also just reducing withdrawing gradually with respect to the spindle axis line.Get back to original position until last knife bar helicla flute, lathe tool is got back to the endoporus of workpiece fully, and promptly liftable drill press spindle unclamps the clamping of workpiece, finally finishes the Vehicle Processing operation of endoporus annular groove.
The effect of steel ball is a guiding.It can only roll and can not move, and half is positioned at helicla flute, and half is positioned at screw, is positioned between helicla flute, screw and the holding screw.
When the spiral fluted number of turns was half-turn, the last amount of feeding of lathe tool that is the processing capacity of endoporus annular groove just equaled the eccentric throw of knife bar and main shaft.Be convenient to the adjustment of processing capacity.
A forced filling oil cup can also be installed on the rear sidewall of eccentric inner hole, be convenient to the lubricating oil of in eccentric inner hole, annotating.Lubricating oil can be used for the lubricated of parts such as stage clip, knife bar, steel ball.
Task of the present utility model comes to this and finishes.
The utility model provides a kind of repeatedly tool setting, repeatedly turning, has repeatedly measured, the working (machining) efficiency height, crudy is good, and can guarantee the uniformity of workpiece, production cost is low, the special turning cutting tool that can process on better simply machining tools such as drilling machine.It can be widely used in the batch machining of endoporus annular groove.
