Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
With reference to Fig. 1, Fig. 2 and Fig. 3, a kind of hydraulic locking dish, comprise locking plate inner conical drogue 9, inner conical drogue 9 is set on hollow shaft 2, working machine main shaft 1 embeds the endoporus of hollow shaft 2, the conical surface of external conical sleeve 8 is combined with the conical surface of inner conical drogue 9, the left part endoporus of external conical sleeve 8 coordinates assembling with the intermediate portion of inner conical drogue 9, junction plane all seals with black box 3, external conical sleeve 8 uses bolt 4 to be connected with pressing plate 5, the left part endoporus of external conical sleeve 8 coordinates assembling with pressing plate 5, junction plane seals with black box 3, pressing plate 5 endoporus coordinate installation with the left part of inner conical drogue 9 again, junction plane seals with black box 3, on external conical sleeve 8, have two oil inlet holes, seal with oil sealing plug 10 and plug screw 11 respectively,
Boss, the pressing plate 5 of inner conical drogue 9 form main oil pocket 6 with external conical sleeve 8, and inner conical drogue 9 intermediate portions have a boss, and can ensure has certain space on main oil pocket 6 axially, make like this high pressure oil squeeze into by oil inlet hole, and prevent inner conical drogue 9 transition slip in the axial direction.
The boss of inner conical drogue 9 and external conical sleeve 8 form secondary oil pocket 7, when maintenance or dismounting, only need to open oil sealing plug 10, oil pressure can be discharged, conical surface junction interference fit disappears, and can realize inner conical drogue 9 and automatically separate with external conical sleeve 8, if inner conical drogue 9 cannot separate with external conical sleeve 8, hydraulic oil can be squeezed in the secondary oil pocket 7 that inner conical drogue 9 and external conical sleeve 8 form, so just can realize completely easily inner conical drogue 9 and separate with external conical sleeve 8.
Main oil pocket 6 uses multiple black boies 3 to be sealed to oil closed cavity with secondary oil pocket 7, and the sealing effect of black box 3 can meet under the effect of high pressure oil, and hydraulic oil does not leak, and ensures that oil pressure pressure stability is constant.
Oil sealing plug 10 can ensure that oil pressure stablizes unchanged.Oil sealing plug 10 is tightened, hydraulic oil can not be flowed out from oil sealing plug 10, but need to ensure that hydraulic oil can squeeze into main oil pocket 6 from plug screw 11, squeeze into hydraulic oil, along with the increase of oil pressure pressure, pressing plate 5 drives external conical sleeve 8 to be moved to the left, and inner conical drogue 9 moves right, therefore inner conical drogue 9 forms interference fit with the conical surface of external conical sleeve 8, also makes output shaft 2 endoporus and working machine main shaft 1 combine closely.Form after required oil pressure pressure, thoroughly tighten oil sealing plug 10, can ensure like this oil pressure pressure of main oil pocket 6, meet the demand of driving torque.
Connecting bolt 4 is just all tightened in the time of initial installation, in maintenance and unloading process afterwards, need not unclamp bolt 4, and locking plate discharges hydraulic oil and just can overhaul, and squeezes into hydraulic oil and gets final product work.
Working principle of the present utility model is:
