Wherein, 1. clamp distributor cover, 1-1. loading and unloading station is into and out of oilhole, and other stations of 1-2. are into and out of oilhole, and 1-3. annular oil groove, 2. clamps distributor mandrel, and 2-1. is into and out of oil duct, and 2-2. mandrel is into and out of oilhole, 3. seal ring, 4. drum axle.
Embodiment
The decisions such as drum type lathe is multi-station machine tool, the structure of the several manufacturing procedures according to part to be processed of its station and lathe arrangement components, station number 3,4,5,6,8, can be 12 if desired conventionally.The drum type of the present embodiment clamps distributor for eight station drum type lathes,
During lathe work, in all stations, except loading and unloading station, the fixture of all the other stations must be in clamped condition, only has loading and unloading station freely to control and clamps and unclamp.Therefore,, on oil circuit control, the oil circuit of loading and unloading station and all the other stations must be arranged apart.
As shown in Figure 9.This drum type hydraulic clamp distributor comprises clamping distributor cover 1 and clamps distributor mandrel 2.Hydraulic pressure oil is delivered in the fixture being arranged on the each station of drum by oil duct and the oilhole of drum axle 4 after distributing by this drum type hydraulic clamp distributor, realizes the clamping of hydraulic control fixture and unclamps.
As Fig. 4, 5, 6, shown in 7 and 8, clamp in distributor mandrel 2 and there are eight groups for entering to hydraulic fixture fuel feeding, fuel-displaced oil duct 2-1, on the excircle of clamping distributor mandrel 2, have and enter, the mandrel of fuel-displaced oil duct 2-1 conducting enters, oil outlet 2-2, mandrel oil inlet hole is the circumferentially distribution of enclosing the land on the excircle that clamps distributor mandrel 2, mandrel oil outlet is the circumferentially distribution of enclosing the land on the excircle that clamps distributor mandrel 2, mandrel enters, oil outlet 2-2 is uniformly distributed on clamping distributor mandrel 2, enter, fuel-displaced oil duct 2-1 is uniformly distributed in a circumferential direction in clamping distributor mandrel 2, and enter, fuel-displaced oil duct 2-1 is inside and outside layering setting each other in clamping distributor mandrel 2.
As shown in Figure 1,2 and 3, clamping distributor cover 1 is enclosed within on clamping distributor mandrel 2, clamp on the excircle of distributor cover 1, arrange two groups totally four into and out of oilhole, be respectively loading and unloading station into and out of oilhole 1-1 and other stations into and out of oilhole 1-2, the loading and unloading station that clamps distributor cover 1 distributes on an axis into and out of oilhole 1-1.On the inner peripheral surface that clamps distributor cover 1, two annular oil groove 1-3 less than whole circle are set, loading and unloading station is into and out of the just in time illogical place in annular oil groove 1-3 of oilhole 1-1, and other stations communicate with two annular oil groove 1-3 respectively into and out of oilhole 1-2,
Clamp distributor mandrel 2 and clamp between distributor cover 1 seal ring 3 that prevents leakage of oil is set.
Drum axle 4 has 8 groups of longitudinal oil ducts and clamps communicating into and out of oil duct 2-1 is corresponding in distributor mandrel 2,8 groups of longitudinal oil ducts of drum axle 4 communicate by the oilhole oil duct corresponding to drum body that radially arrange separately, thereby hydraulic pressure oil is delivered in the fixture being arranged on the each station of drum.
The processing restriction that clamps reason that distributor mandrel 2 and drum axle 4 be divided into two manufactures and be longitudinal oil channel structure causes.
During lathe work, clamping distributor cover 1 maintains static with drum wallboard, and clamp distributor mandrel 2, connect heel with drum, drum axle 4 revolutions with drum axle 4, therefore, clamping distributor mandrel 2 relatively rotates and produces friction with clamping distributor cover 1, in order to improve the wear resistance of part, clamp distributor cover 1 and clamp distributor mandrel 2 and all carry out Quenching Treatment; Drum axle and drum are fixed, and mainly bear the effect of supporting drum, therefore carry out modified heat treatment, improve its comprehensive mechanical performance.
When one of them hydraulic fixture on drum rotates to loading and unloading station, loading and unloading station into and out of oilhole 1-1 respectively with one group of mandrel to this hydraulic fixture fuel feeding into and out of oilhole 2-2 conducting, other stations into and out of oilhole 1-2 by two annular oil groove 1-3 respectively with other mandrels into and out of oilhole 2-2 conducting, thereby the fixture that can realize all the other stations is all in clamped condition.
