Operation principle of the present invention:
Clamping operation principle:
Sliding sleeve 7 advances pressure input adapter 24 input pressure to loop 23, axially being moved to left by sliding sleeve 7 makes it be close to gyroaxis 4, again on clamping pressure input adapter 10 input pressure in clamping pressure input channel 39, clamping check valve 20 and release check valve 19 is entered into by its passage 39, move down at this side's pressure-driven valve ball 52 of clamping check valve 20, thus make pressure output to push away the right chamber 22 of body from clamping check valve 20, drive check valve engine 47 this side of release check valve 19 simultaneously, release Ball of Non-return 45 is moved down, thus make the pressure pushed away in the right chamber 22 of body pass through pressure release in release check valve 19 loop, thus drive and push away body 5 and be moved to the left, while 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 bundle folder is produced to workpiece 9, after workpiece 9 clamps, clamping pressure input adapter 10 pressure disconnects automatically, now sliding sleeve 7 moves right, clamping check valve 20 and release check valve 19 order about valve ball by back-moving spring and engine resets, pressure shutoff is being pushed away in the left chamber 21 of body.The pressure that operating pressure due to sliding sleeve 7 produces when being greater than clamping, thus make when clamping injection pressure, sliding sleeve 7 does not produce and moves to right, and makes it produce sealing, thus make the end face of sliding sleeve 7 forever and gyroaxis 4 be close to, thus effectively ensure the leakage when pressure inputs,
Release operation principle is identical with clamping operation principle, and its difference is that pressure inputs to release pressure input circuit 40 from release pressure input adapter 11.
Cooling circuit system:
By offering cooling circuit in axle bed 3, on bearing outer ring spacer 30, offer the uniform Cooling Holes of cooling to work long hours the huge heat that bearing 6,63 produces for holder simultaneously, by discharging in the cooling circuit 33 offered on support 1 and in axle bed 3, cooling can be entered by driving gas simultaneously, the pressure regulating admission pressure mouth is 0.1 ~ 0.2MPa, pressure likely has impact to bearing grease time too large, can effectively take by cooling circuit the heat that bearing 6,63 produces due to High Rotation Speed out of when the pressure of 0.1 ~ 0.2MPa, make it reach real cooling effect.
Reduce centrifugation systems:
The quality effectively changing part 9 carries out Balance Treatment simultaneously; bearing 6,63 is made to bear optimum pressure; effectively protect running accuracy and the service life of bearing 6,63, thus extend the service life of holder and the stability of precision, thus effectively reduce the centrifugal force of holder High Rotation Speed generation.
Oil return:
When adopting hydraulic pressure as driving pressure source, backflash has been offered in sliding sleeve seal cover 8, simultaneously offer uniform hole at oil-recovery tank in below to flow in the oil return line that support 1 offers, and be back in Hydraulic Station by back leakage connection 37, so reach the general effect of gas-liquid.
Comprehensively above-mentioned: to be only preferred embodiment of the present invention; although the present invention discloses as above with preferred embodiment; not limit practical range of the present invention with this; therefore: all equivalence changes done according to shape of the present invention, structure, principle, all should be covered by within protection scope of the present invention.
