Description
Technical field
The utility model belongs to technical field of machining tools, is related to a kind of knurling tool, and especially a kind of pretightning force can
Adjust knurling tool.
Background technique
Knurling tool, which is used to process metal surface, makes it generate certain plastic deformation and form decorative pattern, plays anti-skidding and is convenient for
The effect of torsion.During annular knurl, the knurled wheel of knurling tool needs to apply biggish radial pressure to the surface of workpiece, this pressure
If advocating to be provided by the middle pulley of lathe, before opening main axis, middle pulley is shaken, annular knurl of the clamping on knife rest is made
Knife is fed forward, and the surface of the hobboing cutter wheel contact workpiece of knurling tool simultaneously generates certain pretightning force, and being then turned on main shaft makes workpiece
Rotation, then carry out self-acting feed and implement annular knurl processing.Due to annular knurl processing be by knurled wheel to workpiece generate plastic deformation and
It is formed, the size of the power that knurling tool applies workpiece is to the depth of decorative pattern caused by annular knurl and prevents annular knurl from generating random line
There is large effect, if pressure is excessive, do not only result in that decorative pattern is too deep, also will cause knurled wheel crosses quick-wearing, can also make
The screw-driven pair that cutter setting frame plays the role of the middle slide plate of transmitting causes to wear, or even generates end to dress chucked work workpiece
Face bounce, influences to process.If the pressure that annular knurl applies is not big enough, cause knurled pattern excessively shallow, or even generates random line phenomenon.
Summary of the invention
The purpose of this utility model is the presence of the above problem in view of the prior art, proposes a kind of adjustable annular knurl of pretightning force
Knife adjusts knurling tool to the pretightning force of workpiece, solves the problems, such as background technique.
The purpose of this utility model can be realized by the following technical scheme: a kind of adjustable knurling tool of pretightning force, including knife
Head and knife handle roll on cutter head and are provided with knurled wheel, which is characterized in that the cutter head and the scalable connection of knife handle, the cutter head
It is connected with slide bar, the top of the knife handle offers guide groove along its length, in the scalable insertion guide groove of slide bar,
The tail end of knife handle offers the lifting hole being connected with the guide groove, and the end of the slide bar is fixed with lifting rod, lifting rod
On offer external screw thread, the end of lifting rod is arranged with compressed spring on the lifting rod from being pierced by guide groove to lifting hole,
One end of compressed spring and the end of slide bar are against the end of the other end and guide groove is against the lifting rod stretches out lifting hole
End be combined with locking nut；The side of the knife handle offers the sliding slot being connected with the guide groove, the slide bar
Side is fixed with indicating arm, and the top of indicating arm is stretched out outside sliding slot, and quarter is distributed in length direction along the chute for the side of the knife handle
Angle value.
Its working principles are as follows: clamping is when on knife rest, knife handle tool by the knife handle clamping of this knurling tool on lathe saddle
There is the side of scale value and indicating arm outwardly, rotates the middle handwheel of lathe middle slide plate, make knurled wheel and workpiece surface to be processed
Against continuing to rotate middle handwheel, slide bar makes the compressed spring being arranged in knife handle guide groove generate flexible deformation, according to compression bullet
Spring generates the amount of flexible deformation to distinguish out the pretightning force that knurled wheel generates workpiece surface, and the numerical value of reading is according to indicating arm
Scale value in knife handle side is read, so as to adjust preload of the knurling tool to workpiece according to the needs of annular knurl actual processing
Power.During knurling tool applies pretightning force to workpiece surface, slide bar slides in guide groove, and indicating arm slides in sliding slot, refers to
To the size for being distributed in power corresponding to scale value corresponding to knife handle side, the size of power is equal to the coefficient of elasticity of compressed spring
Multiplied by the flexible deformation length of spring, therefore, indicating arm can be reacted relative to the distance that scale value is moved by scale value
The size of pretightning force out, when slide bar and compressed spring contradict and compressed spring is indicating arm and scale when generating flexible deformation
The zero curve of value is aligned.In actual production process, it is required apply pretightning force size according to the diameter of processing part with
And hardness of material etc. is obtained by actual processing experience.It is to prevent from pressing that the effect of lifting rod and locking nut is arranged in this knurling tool
The excessive rebound of contracting spring upon compression reduces compression travel, when knurled wheel and workpiece become against making compressed spring generate elasticity
After shape, lifting rod is toward elongation outside lifting hole, and when indicating arm is close to required corresponding scale value, rotation lock nut makes to lock
The end of tight nut and knife handle is against then when annular knurl completes the process withdrawing, lifting rod is locked nut latching, prevents
Cutter head rebound, reduces the compression travel of cutter head when annular knurl is processed next time, improves processing efficiency.
Above-mentioned slide bar cross section is in rectangle, and the cross section of the guide groove is in rectangle, and slide bar is slidably plugged in guiding
In slot.
The bottom end of above-mentioned indicating arm and the side of slide bar are detachably fixed, and are assembled for convenience, are initially charged with guiding in slide bar
After slot, then indicating arm and slide bar fixed.
The bottom end of above-mentioned indicating arm offers external screw thread, and the side of slide bar offers threaded hole, and the bottom end of indicating arm screws in
In the threaded hole.
Above-mentioned cutter head and slide bar are integrally formed, and improve rigidity.
Compared with prior art, the utility model has the advantage that
1. the utility model can distinguish out knurling tool to the pressure of workpiece by indicating arm and scale value, prevent annular knurl
Decorative pattern is too deep and excessively shallow, improves the accuracy of processing, and prevents cutter and lathe from causing excessive wear.
2. the utility model, by setting lifting rod and locking nut, slide bar is reduced to the compression travel of compressed spring,
The time for reaching corresponding pretightning force when saving to knife, improve processing efficiency.
3. the utility model also has structure simple, the applicable and strong advantage of generalization.
