Two to six holes are provided with, to install object lens, rotary turnplate can make the object lens of different multiples successively turn to microscopical light
On shaft position, guarantee the light sympodium of object lens and eyepiece.In order to keep turntable rotation more smooth, set between price fixing and turntable inner wall
It is equipped with ball and washer, in order to limit ball scrolling position, design has step to form stepped hole on turntable inner wall.These stepped holes
Processing, be usually used scroll chuck clamping rotary disk outer circumference surface carry out turnery processing, contact of the scroll chuck with turntable
Area is small, and clamping reliability is low, and in process, turntable is easily displaced, and processes the inner hole of turntable and elliptical phenomenon occurs,
Reduce turning quality.
Summary of the invention
The object of the present invention is to provide a kind of turntable inner hole vehicle clampers, and it is microscopical that this fixture can solve existing object lens
The low problem of turntable inner hole vehicle clamper clamping reliability.
To solve the above-mentioned problems, the technical solution adopted by the present invention is that: this turntable inner hole vehicle clamper include be equipped with not
The clamp body of formula taper shank, the clamp body further include with the integrally formed connecting plate of the Morse taper shank and locating shaft, it is described fixed
Position axis and the Morse taper shank are coaxially disposed, and the connecting plate is arranged between the Morse taper shank and the locating shaft；It is described
Positioning shaft sleeve is equipped with elastic collet, elastic opening portion group of the elastic collet by attachment base and for clamping turntable outer peripheral surface
At；Abutment sleeve is set with outside the elastic collet, the abutment sleeve has the fixing seat being connected with the attachment base, institute
It states attachment base and the fixing seat is connected and fixed by bolt and the connecting plate；Pressure is fitted in the end of the abutment sleeve
Set, the pressing sleeve include pressing plate for crimping the end face of the turntable and be inserted into the abutment sleeve and the elastic collet it
Between sleeve, the internal diameter of the sleeve is gradually reduced by insertion end towards the pressing plate direction；The abutment sleeve, which is provided with, to be used for
Lock the clamping screw of the pressing sleeve.
In the technical solution of above-mentioned turntable inner hole vehicle clamper, more specific technical solution may also is that the locating shaft is
Multi-diameter shaft, the outer shaft section diameter of the multi-diameter shaft are less than shaft section diameter connect with the connecting plate, the locating shaft and
It is abutted against at the top of the turntable.
Further, the clamping screw is inserted into from the wall body of the abutment sleeve and offsets with the outer surface of the sleeve
It connects.
Further, the internal diameter of the pressing plate is less than or equal to the internal diameter of the turntable end face.
Further, the outer wall in the elastic opening portion is provided with oblique surface close to free end.
By adopting the above-described technical solution, compared with prior art, the present invention has the following advantages: setting positioning
Sleeve and elastic collet are inserted between abutment sleeve and elastic collet by pressing sleeve, enable the periphery of elastic collet clamping rotary disk
Face, it is ensured that the radial clamping of turntable, meanwhile, pressing sleeve crimp turntable end face, with locating shaft at the top of cooperate, realize to turn
The axial grip of disk avoids to improve the reliability of turntable for clamping and generates displacement in process, improve in turntable
The turning quality in hole.
