Line is connected, and the adjusting screw rod 6 is located in the stepped hole 2-1 of return piston 2, and one end and the load of return piston end cap 8, described
Screw sleeve 5 is sleeved on adjusting screw rod 6 and is threadedly coupled with the non-self-lock-ing of adjusting screw rod 6.
As shown in Fig. 1,4,5,6, the middle part of the adjusting screw rod 6 has annular boss 6-1, the end face ring gearwheel clutch
7 include first end face gear ring 7-1 and second end face gear ring 7-2, and the first end face gear ring 7-1 is fixed with return piston end cap 8
Connect or be formed integrally, the second end face gear ring 7-2 is fixed on adjusting screw rod 6 and offseted with annular boss 6-1 side,
Second elastic component 17 is located in the stepped hole 2-1 of return piston 2, and is sleeved on adjusting screw rod 6, the second elastic component 17
Side and annular boss 6-1 opposite side offset, and opposite side offsets with the step 2-1-1 in the stepped hole 2-1 of return piston 2.
As shown in Fig. 1,8, the guide rod 3 is sleeved on screw sleeve 5, and one end of guide rod 3 is consolidated with the screw thread of cylinder body 13
Fixed connection, equipped with regulation spring 10 between the guide rod 3 and screw sleeve 5, regulation spring 10 hoop is connected on screw sleeve 5, described
Regulation spring end cap 11 is sleeved on screw sleeve 5, and is threadedly coupled with the other end of guide rod 3.Certainly, it can also be described lead
There is the ring-shaped step offseted with cylinder body 13 to the middle part of bar 3, one end of guide rod 3 is fixedly connected on cylinder body by nut 18
On 13.
As shown in Fig. 1,2,3,7, steady pin 5-1 is also equipped with the screw sleeve 5, steady pin 5-1 end, which is located at, to be resetted
In axial groove 2-2 in the stepped hole 2-1 of piston 2, the rotation of screw sleeve 5 is limited, screw sleeve 5 is moved axially.
As shown in figure 1, first elastic component 16 is sleeved on return piston 2, and two ends respectively with return piston 2 and bullet
The side of spring base 12 offsets.
The opposite side of the spring pedestal 12 offsets with base bonnet 9.
Also there is screw sleeve end cap 4, one end of the screw sleeve end cap 4 is sleeved on the other end of adjusting screw rod 6, and
It is threadedly coupled with screw sleeve 5, the other end of the screw sleeve end cap 4 has annular stop 4-1, the power for transmitting screw sleeve.
The elastic component 17 of first elastic component 16 and second is disc spring, can be very good to store and releases energy.
Closure 15 is housed on the base bonnet 9, dustproof effect is played.
Bushing 14 is set with the regulation spring 10, and the bushing 14 is located in guide rod 3, plays protection part and profit
Sliding effect.
Having as shown in Fig. 1,7, on the adjusting screw rod 6 has internal thread 5-2 on external screw thread 6-2, the screw sleeve 5,
The external screw thread 6-2 and internal thread 5-2 is non-self-lock-ing screw thread.
As shown in figure 1, the regulation spring 10 binds round with screw sleeve 5 and connect in succession, i.e., when the axially loaded of screw sleeve 5 is more than screw sleeve
5 and regulation spring 10 between frictional force when, screw sleeve 5 can with regulation spring 10 produce axially opposing slip.
As shown in figure 1, in the use of the present invention, oil cylinder discharge oil, reset can be promoted by losing the first elastic component 16 of oil pressure
Piston 2 and piston 1 move right, and the return piston end cap 8 being now threadedly coupled with return piston 2 can pass through end face gear ring clutch
Device 7 promotes adjusting screw rod 6 to move right, and drives the screw sleeve 5 being threadedly coupled with it to move by adjusting screw rod 6, eventually through
The screw sleeve end cap 4 being threadedly coupled with screw sleeve 5 outwards transmits brake force.Now, due to the first end of end face ring gearwheel clutch 7
Face gear ring 7-1 fits with second end face gear ring 7-2, limits the rotation of adjusting screw rod 6, and is also equipped with steady pin on screw sleeve 5
5-1, steady pin 5-1 end are located in the axial groove 2-2 in the stepped hole 2-1 of return piston 2, limit turning for screw sleeve 5
It is dynamic, screw sleeve 5 is moved axially, thus adjusting screw rod 6 and screw sleeve 5 are relatively unrotatable.
When the logical oil of oil cylinder, piston 1 is moved to the left with return piston 2 in the presence of oil pressure, until hoop is connected on tune in succession
The left side of regulation spring 10 on section screw rod 6 offsets with regulation spring end cap 11, is connect in succession because regulation spring 10 is bound round with screw sleeve 5, if
Now oil pressure continuation effect is moved to the left adjusting screw rod 6, and the frictional force between regulation spring 10 and screw sleeve 5 can hinder screw sleeve
5 are moved to the left, and screw sleeve 5 is stopped movement, and the return piston end cap 8 being now threaded on return piston 2 continues with multiple
Position piston 2 is moved to the left together so that the first end face gear ring 7-1 being fixed on return piston end cap 8 is with being fixed on regulation spiral shell
Second end face gear ring 7-2 on bar 6 is changed into disengaged condition from original fit-state, while the second elastic component 17 is compressed, and by
It is that non-self-lock-ing is threadedly coupled and steady pin 5-1 limits the rotation of screw sleeve 5 in screw sleeve 5 and adjusting screw rod 6, therefore second
The thrust lower adjusting screw rod 6 of elastic component 17 carries out rotation, until second end face gear ring 7-1 and first end face gear ring 7-2 again
Secondary laminating, adjusting screw rod 6, which stops operating, no longer to be stretched out, and the total length after adjusting screw rod 6 is threadedly coupled with screw sleeve 5 increases, and rises
Arrived the effect of regulation compensation, this regulative mode be threadedly coupled with screw sleeve 5 by changing adjusting screw rod 6 after total length,
To realize regulation compensation, when piston small stroke, the regulated quantity of single can also be very big.
