Operation principle of the present utility model:

Clamp operation principle:

Sliding sleeve 7 advances pressure input adapter 24 input pressures to loop 23, sliding sleeve 7 is axially moved to left and makes it be close to gyroaxis 4, again on clamping pressure input adapter 10 input pressure to clamping pressure input channel 39, by its passage 39, enter into and clamp check valve 20 and discharge check valve 19, at clamping check valve 20 these side's pressure-driven valve balls 52, move down, thereby make pressure output to and push away the right chamber 22 of body from clamping check valve 20, discharging check valve 19 these sides' driving check valve engines 47 simultaneously, making to discharge Ball of Non-return 45 moves down, thereby the pressure that makes to push away in the right chamber 22 of body passes through to discharge pressure release in check valve 19 loops, thereby driving pushes away body 5 and is moved to the left, when driving left-hand cylinder body 13 to be moved to the left, left-hand cylinder folder 16 produces bundle folder workpiece 9, under the effect of extension bar 15, drive right collet chuck 18 to move to left simultaneously, order about right collet chuck 18 and also workpiece 9 is produced to bundle folder, after workpiece 9 clamps, clamping pressure input adapter 10 pressure disconnect automatically, now sliding sleeve 7 moves right, clamping check valve 20 by back-moving spring, orders about valve ball with release check valve 19 and engine resets, make pressure shutoff in pushing away the left chamber 21 of body.Because the operating pressure of sliding sleeve 7 is greater than the pressure producing while clamping, thereby make when clamping injection pressure, sliding sleeve 7 does not produce and moves to right, and makes it produce sealing, thus the end face that makes sliding sleeve 7 forever and gyroaxis 4 be close to, thereby effectively guarantee the leakage when pressure is inputted,

Discharge operation principle identical with clamping operation principle, its difference is that pressure inputs to release pressure input circuit 40 from release pressure input adapter 11.

Cooling circuit system:

By offer cooling circuit in axle bed 3, on bearing outer ring spacer 30, offer cooling uniform Cooling Holes for the holder huge heat that bearing 6,63 produces that works long hours simultaneously, by discharging on support 1 and in the cooling circuit 33 of offering in axle bed 3, can enter cooling by driving gas simultaneously, regulating the pressure of admission pressure mouth is 0.1～0.2MPa, when pressure is too large, likely bearing grease is had to impact, when the pressure of 0.1～0.2MPa, can effectively take bearing 6,63 out of due to the heat that High Rotation Speed produces by cooling circuit, make it reach real cooling effect.

Reduce centrifugation systems:

The quality that effectively changes part 9 is carried out Balance Treatment simultaneously; make bearing 6,63 bear optimum pressure; effectively protect running accuracy and the service life of bearing 6,63, thereby extend the service life of holder and the stability of precision, thereby effectively reduce the centrifugal force that holder High Rotation Speed produces.

Oil return:

When adopting hydraulic pressure as driving pressure source, in sliding sleeve seal cover 8, offered backflash, simultaneously oil-recovery tank below offer uniform hole and flow in the oil return line that support 1 offers, and be back in Hydraulic Station by back leakage connection 37, so reached the general effect of gas-liquid.

Comprehensively above-mentioned: to be only preferred embodiment of the present utility model; although the utility model discloses as above with preferred embodiment; not with this, limit practical range of the present utility model; therefore: all equivalences of doing according to shape of the present utility model, structure, principle change, within all should being covered by protection domain of the present utility model.
