Description
Technical field:
The utility model relates to a kind of knife handles with dynamic balance adjustment function.
Background technique:
In use, its revolving speed is higher on machining knife handle in machining center lathe, it is desirable to the balance of knife handle component
Property it is higher, otherwise can be made due to the imbalance of knife handle machine tool spindles generate vibration, thus reduce main shaft precision and processing essence
Degree, or even shorten the service life of machine tool chief axis.
The knife handle of standard component structure used at present is mainly the taper shank being connected by one end with processing center machine tool main shaft,
The other end opposite with taper shank is the button for clamping cutter, close to the cyclic annular clamping part of button on two groove depths being relatively set with
Inconsistent keyway is spent, the groove depth of one of keyway is less than the groove depth of another keyway.The groove depth knot of this keyway
The inconsistent knife handle of structure, makes knife handle center of gravity shift, and to knife handle, this body structure brings disequilibrium, therefore
And the problem of causing knife handle disequilibrium during knife handle rotation, directly damage processing center machine tool main shaft
Precision and machining accuracy and service life.
Utility model content:
The purpose of the utility model is to provide a kind of knife handle with dynamic balance adjustment function, errors
It is small, precision is high, dynamic balancing after easy to use, adjustable cutter clamping.
Above-mentioned purpose is realized by following technical scheme:
A kind of knife handle with dynamic balance adjustment function, composition includes: holder main body, and the holder main body is hollow
Structure, one end of the holder main body are the taper shank connecting with lathe, and the other end of the cutter body is clamping cutter
Button, there is on the side wall of the button flat balanced surface, the side wall of the button side corresponding with flat balance face
There is coarse balance threaded hole on wall, adjusting screw, the side of the button are installed on the coarse balance threaded hole
Fine tuning dynamic balance adjusting apparatus is installed, the fine tuning dynamic balance adjusting apparatus includes annular groove, the annular groove
It is upper to be fixed by bolt and regulating part.
The knife handle with dynamic balance adjustment function, described when holding cutter diameter less than 20mm, the fine tuning
The quantity of dynamic balance adjusting apparatus is 4.
The knife handle with dynamic balance adjustment function, when the clamping cutter diameter is greater than 20, the fine tuning
The quantity of dynamic balance adjusting apparatus is 6.
The utility model has the advantages that
The utility model structure is simple, has well solved knife handle balance problem, ensures knife handle when high revolving speed uses
Good machining accuracy, while effective protection machine tool chief axis precision and service life.
The other side side wall opposite with threaded hole is equipped with flat balanced surface on the utility model cutter holding end, so that knife
The cross section for having clamping end is in non-circular structure.Structure is simple, by the improvement of above structure, has effectively canceled out threaded hole
And the amount of unbalance of housing screw, knife handle balance problem has been well solved, has ensured that knife handle is good when high revolving speed uses
Machining accuracy, while effective protection machine tool chief axis precision and service life, have been obviously improved the surface quality of work piece.
The utility model not only reduces the accumulated error in processing, improves coaxial precision, and cutter is obtained
Higher rigidity.By being equipped with adjusting screw on adjustment coarse balance threaded hole before installing, carrys out coarse adjustment computing ballance correction, make
It reaches standard requirements.Adjustment fine tuning dynamic balance adjusting apparatus can use at high speed in this way.
Detailed description of the invention:
Attached drawing 1 is the structural schematic diagram of the utility model.
Attached drawing 2 is the left view of attached drawing 1.
Specific embodiment:
Embodiment 1:
A kind of knife handle with dynamic balance adjustment function, composition includes: holder main body 1, during the holder main body is
Hollow structure, one end of the holder main body are the taper shank 2 connecting with lathe, and the other end of the cutter body is clamping knife
The button 3 of tool, has flat balanced surface 4 on the side wall of the button, and the side wall of the button is corresponding with flat balance face
Side wall on there is coarse balance threaded hole 5, adjusting screw is installed on the coarse balance threaded hole, the button
Side is equipped with fine tuning dynamic balance adjusting apparatus, and the fine tuning dynamic balance adjusting apparatus includes annular groove 6, the annular
It is fixed by bolt 7 and regulating part 8 on sliding slot.
Fine tuning dynamic balance adjusting apparatus uses side adjustment structure, and the limited step of regulating part is correspondingly arranged at by when installation
In annular groove, sliding block and ring body are squeezed by bolt and fixed, sliding block is adjusted in the position of ring body according to the cutter of installation.?
In knife handle rotary operation, if screw loosens, under the influence of centrifugal force, sliding block can only rotate in annular groove, avoid
Security risk caused by sliding block pop-up ring body.
Embodiment 2:
It is described when holding cutter diameter less than 20mm according to the knife handle described in embodiment 1 with dynamic balance adjustment function,
The quantity of the fine tuning dynamic balance adjusting apparatus is 4.
Embodiment 3:
According to the knife handle described in embodiment 1 with dynamic balance adjustment function, when the clamping cutter diameter is greater than 20,
The quantity of the fine tuning dynamic balance adjusting apparatus is 6.
