Dynamical type collet.
Background technology
In order to make the mode of operation of mechanical processing more convenient, more meet the processing program of diversity and elasticity, it is various not
Composition with processing unit (plant) and fixture is continuously available improvement, and its function is continuously available enhancement.
By taking general workpiece needs to carry out eccentric processing as an example, traditional mode is by workpiece to deviate the live spindle of lathe
The collet that the mode in axle center is folded in lathe is processed, and such sandwiched mode needs gradually to adjust each clamping jaw of collet manually
Position, recycle clamping jaw fix the workpiece to be processed, entirely process it is slow and inefficent, thus also it is necessary to maintain plus
Under the premise of work efficiency rate, related disadvantage is overcome.
Invention content
Therefore, the main purpose of the present invention is to provide a kind of operations and the power easy to use for manually adjusting eccentricity
Formula collet.
In order to reach foregoing invention purpose, the dynamical type collet provided by the present invention for manually adjusting eccentricity includes master
Body, clamping device, counterweight and cushion block；The main body can be rotated centered on rotary shaft；The clamping device is with can be along dynamic
The mode for making path reciprocating movement is installed in the main body；The counterweight is set in a manner of it can move in the main body；It should
Cushion block is set between the clamping device and the main body so that rotating shaft eccentric displacement of the clamping device relative to the main body.
Thus, it is only necessary to select the cushion block of appropriate height that can change the center displacement amount of clamping device, user can conveniently and
Effectively make clamping device displacement to process eccentric work piece, while voluntarily elasticity can also adjust counterweight, makes whole bias
The whole center of gravity of collet and workpiece is maintained at settling position.

Specific implementation mode
It please refers to Fig.1 to shown in Fig. 6, what a preferred embodiment of the present invention was provided manually adjusts the dynamical type folder of eccentricity
Head includes main body 10, clamping device 20 and counterweight 30, and main body 10 is in substantially discoid, and main body 10 can be set to lathe
Live spindle on so that main body 10 is rotated in place centered on rotary shaft.12 central position of front end face of main body 10 is equipped with
Groove 14,14 both sides of groove are respectively equipped with the first T-slot 16 being mutually parallel, and the periphery wall of main body 10 is concavely provided with the 2nd T shapes
Slot 18.Counterweight 30 is moved along the periphery of main body 10 by the way that several are set to T-shaped block 19 of the second T-slot 18, also,
T-shaped block 19 can be lockked depending on demand, to which counterweight 30 to be positioned in main body 10.The front end face 12 of main body 10 is equipped with side
Wall 11, side wall 11 extend along the part edge of main body 10 and form the guide groove 13 opened towards side, and side wall 11 corresponds to
The inner peripheral surface of guide groove 13 is equipped with the first positioning plane 15.
Clamping device 20 includes in substantially cylindric pedestal 22, and the end of pedestal 22 is embedded that there are three can be radially
The ring-type perisporium of mobile axial prong 24, pedestal 22 is internally provided with plunger 26, check plate 28, bolt 40 and adjustment nut 42.
The front end of plunger 26 is mutually chimeric with three axial prongs 24, and check plate 28 is fixed on the rear end of plunger 26, and check plate 28 is equipped with one
A radial direction splitting groove 29, bolt 40 are arranged in splitting groove 29, and adjustment nut 42 is screwed together in bolt 40, and is resisted against check plate
On 28.When changing relative position of the adjustment nut 42 on bolt 40, you can by adjusting the head of nut 42 and bolt 40
41 pull check plate 28 and plunger 26 together, and then each axial prong 24 is driven to move, so as to adjust location dimension.
Clamping device 20 is incorporated into the guide groove of main body 10 by T-shaped block 19 that several are set in the first T-slot 16
Inside 13, to make clamping device 20 be set in main body 10 in a manner of it can move, and regarding demand lock T-shaped block 19 and
Clamping device 20 is positioned in main body 10.Pedestal 22 is set there are two locating piece 46, which is embedded at main body 10
Groove 14 in, so as to guide clamping device 20 along rectilinear direction accurately displacement.
It also is provided with corresponding to the second of the first positioning plane 15 on the ring-type perisporium outer surface of the pedestal 22 of clamping device 20
Plane 25 is positioned, cushion block can be set between the first positioning plane 15 of main body 10 and the second positioning plane 25 of clamping device 20
60, so that clamping device 20 is deviated preset distance along guide groove 13 using the thickness of cushion block 60, you can to produce the work of center displacement
With.User only needs the cushion block 60 according to the eccentric size selection suitable thickness processed, it will be able to obtain accurately eccentric position
Shifting amount.
Please also refer to Fig. 6 and Fig. 7, when cushion block 60 is arranged between pedestal 22 and main body 10, clamping device 20 is
The effect of center displacement can be generated, and user can voluntarily adjust the position of counterweight 30, make counterweight 30 be located at it is symmetrical and
The center of gravity of mean allocation entirety eccentric clamping and workpiece and keep it in rotation center of gravity position, it will be able to make collet high speed
Eccentric vibrating phenomenon will not occur when rotation.
It is noted that when clamping device 20 deviates, since bolt 40 is the splitting groove 29 across check plate 28, because
And the movement of clamping device 20 does not affect bolt 40 and nut 42, can produce the effect mutually staggered with displacement just.
By above-mentioned component parts, the present invention only needs to select the cushion block of appropriate height can change the inclined of clamping device
Heart displacement, user can easily and efficiently make clamping device displacement to process eccentric work piece, while can also be voluntarily
Elasticity adjustment counterweight, makes the whole center of gravity of whole eccentric clamping and workpiece be maintained at settling position, promotes machining accuracy and matter
Amount, whole manufacturing cost of the invention are relatively low.
