Description
Technical Field
The utility model relates to a chuck clamping device especially relates to a chuck clamping device.
Background
Chuck clamping device who uses among the prior art adopts three jack catch to carry out the centre gripping, the chuck is by three jack catch centre gripping back, the jack catch is locked to realize the rotary machining of lathe, but this kind of centre gripping mode has certain limitation, especially to the aspect of the centre gripping location of irregular cylinder, the centre gripping is not tight, does not fix a position the work piece axial, leads to producing in the course of working easily not hard up or axial position takes place the deviation, leads to the rejection rate to rise, simultaneously in high accuracy processing, the effect is not ideal.
Therefore, the prior art has yet to be developed.
SUMMERY OF THE UTILITY MODEL
In view of the above prior art's shortcoming, the utility model aims to provide a chuck clamping device for solve among the prior art the problem that the chuck clamping device centre gripping does not tightly lead to the rejection rate to rise.
In order to achieve the above objects and other related objects, the utility model provides a chuck clamping device, including chuck, jack catch and additional jack catch, be equipped with the jack catch on the chuck, the jack catch top is equipped with additional jack catch, be equipped with the work piece on the additional jack catch.
In an embodiment of the present invention, the number of the claws is three, and the claws are 120 ° between two pairs.
In an embodiment of the present invention, the additional claws are three, the additional claws are disc-shaped, and the positions of the three additional claws correspond to the positions of the three claws.
In an embodiment of the present invention, the additional claws are provided with grooves.
In an embodiment of the present invention, the additional claw is provided with a buckle adapted to the claw.
As described above, the utility model discloses a chuck clamping device has following beneficial effect: the three additional clamping jaws are added, the end faces of the additional clamping jaws are subjected to finish machining and surface treatment, after a workpiece is fixed, the radial clamping effect is kept, the axial positioning of the workpiece is also increased, the clamping precision of the chuck is greatly improved, the machining precision is greatly improved particularly in the machining process of high speed and large feed amount, and the yield is improved.
