As shown in Figure 1, 2, 3, one end of described return piston 2 and piston 1 offset, the other end and return piston end cap 8 spiral shellsLine connects, and described adjusting screw(rod) 6 is arranged in the stepped hole 2-1 of return piston 2, and one end and 8 loads of return piston end cap, described inScrew sleeve 5 is sleeved on adjusting screw(rod) 6 and with the non-self-locking thread of adjusting screw(rod) 6 and is connected.
As shown in Fig. 1,4,5,6, the middle part of described adjusting screw(rod) 6 has annular boss 6-1, described end face gear ring clutch7 comprise the first end face gear ring 7-1 and the second end face gear ring 7-2, and described the first end face gear ring 7-1 and return piston end cap 8 are fixingConnect or make one, described the second end face gear ring 7-2 is fixed on adjusting screw(rod) 6 and with a side of annular boss 6-1 and offsets,Described the second elastic component 17 is arranged in the stepped hole 2-1 of return piston 2, and is sleeved on adjusting screw(rod) 6, the second elastic component 17The opposite side of one side and annular boss 6-1 offsets, and the step 2-1-1 in the stepped hole 2-1 of opposite side and return piston 2 offsets.
As shown in Fig. 1,8, described guide post 3 is sleeved on screw sleeve 5, and one end of guide post 3 and cylinder body 13 screw threads are solidFixed connection, between described guide post 3 and screw sleeve 5, be equipped with and regulate spring 10, described adjusting spring 10 hoops are connected on screw sleeve 5, described inRegulate spring end cap 11 to be sleeved on screw sleeve 5, and be threaded with the other end of guide post 3. Certainly, lead described in can being alsoHave the ring-shaped step offseting with cylinder body 13 to the middle part of bar 3, one end of guide post 3 is fixedly connected on cylinder body by nut 18On 13.
As shown in Fig. 1,2,3,7, on described screw sleeve 5, steady pin 5-1 is also housed, the end of steady pin 5-1 is positioned at resetIn axial groove 2-2 in the stepped hole 2-1 of piston 2, the rotation of restriction screw sleeve 5, can only move axially screw sleeve 5.
As shown in Figure 1, described the first elastic component 16 is sleeved on return piston 2, and two ends respectively with return piston 2 and bulletOne side of spring base 12 offsets.
The opposite side of described spring pedestal 12 and base bonnet 9 offset.
Also have screw sleeve end cap 4, one end of described screw sleeve end cap 4 is sleeved on the other end of adjusting screw(rod) 6, andBe threaded with screw sleeve 5, the other end of described screw sleeve end cap 4 has annular stop 4-1, for transmitting the power of screw sleeve.
Described the first elastic component 16 and the second elastic component 17 are dish spring, can well store and release energy.
On described base bonnet 9, seal cover 15 is housed, plays dustproof effect.
On described adjusting spring 10, be set with lining 14, and described lining 14 is positioned at guide post 3, plays protection part and profitSliding effect.
As shown in Fig. 1,7, on described adjusting screw(rod) 6, there is external screw thread 6-2, on described screw sleeve 5, there is internal thread 5-2,Described external screw thread 6-2 and internal thread 5-2 are non-self-locking thread.
As shown in Figure 1, described adjusting spring 10 binds round in succession and connects with screw sleeve 5, when screw sleeve 5 axially loadeds are greater than screw sleeve5 and while regulating the frictional force between spring 10, screw sleeve 5 can produce axial relative sliding with regulating spring 10.
As shown in Figure 1, in use, oil cylinder is discharged oil to the utility model, and the first elastic component 16 that loses oil pressure can promoteReturn piston 2 and piston 1 move right, and the return piston end cap 8 being now threaded with return piston 2 can be by end face gear ringClutch 7 promotes adjusting screw(rod) 6 and moves right, and drives the screw sleeve 5 being threaded with it to move by adjusting screw(rod) 6, finalOutwards transmit brake force by the screw sleeve end cap 4 being threaded with screw sleeve 5. Now, due to of end face gear ring clutch 7One end face gear ring 7-1 and the second end face gear ring 7-2 laminating, limited the rotation of adjusting screw(rod) 6, and on screw sleeve 5, be also equipped with solidRationed marketing 5-1, the axial groove 2-2 that the end of steady pin 5-1 is arranged in the stepped hole 2-1 of return piston 2, is limiting screw sleeve 5Rotation, screw sleeve 5 can only be moved axially, thereby adjusting screw(rod) 6 and screw sleeve 5 can not relatively rotate.
In the time of the logical oil of oil cylinder, be moved to the left at effect lower piston 1 and the return piston 2 of oil pressure, until hoop is connected on tune in successionThe left side of the adjusting spring 10 on joint screw rod 6 offsets with regulating spring end cap 11, connects owing to regulating spring 10 and screw sleeve 5 to bind round in succession, ifNow oil pressure continuation effect is moved to the left adjusting screw(rod) 6, regulates the frictional force between spring 10 and screw sleeve 5 can hinder screw sleeve5 are moved to the left, and screw sleeve 5 are stopped mobile, and the return piston end cap 8 being now threaded on return piston 2 continues with multiplePosition piston 2 is moved to the left together, makes to be fixed on the first end face gear ring 7-1 on return piston end cap 8 and is fixed on adjusting spiral shellThe second end face gear ring 7-2 on bar 6 becomes disengaged condition from original fit-state, compresses the second elastic component 17 simultaneously, again byBe connected and steady pin 5-1 has limited the rotation of screw sleeve 5 for non-self-locking thread in screw sleeve 5 and adjusting screw(rod) 6, therefore secondUnder the thrust of elastic component 17, adjusting screw(rod) 6 carries out rotation, until the second end face gear ring 7-1 and the first end face gear ring 7-2 are againInferior laminating, adjusting screw(rod) 6 stops operating and no longer stretches out, and the total length after adjusting screw(rod) 6 is threaded with screw sleeve 5 increases, and risesArrive the effect that regulates compensation, the total length after this regulative mode is threaded with screw sleeve 5 by change adjusting screw(rod) 6,Realize and regulate compensation, even in the time of the little stroke of piston, the regulated quantity of single also can be very large.
