Rear cover sealing ring 53 setting to a certain extent can avoid chamber 4 in medium through the slot leakage between rear cover 5 and cylinder body 1 extremely
Outside cylinder body 1, there is the preferable effect of leakproofness.
As shown in Figure 1,2 center of piston is provided in the axial direction with adjustment hole 21, piston 2 is located on an end face of first chamber 41
Jack 10 is offered, one end of piston rod 3 is threadingly attached in adjustment hole 21, and 3 a part of piston rod passes through adjustment hole
It is located in first chamber 41 after 21, the threaded one end that piston rod 3 is located at first chamber 41 is connected with locking nut 6, and piston rod 3
Diameter positioned at 21 part of adjustment hole is less than the diameter positioned at 12 part of punched out；Piston rod 3 is located at the one end of punched out 12
Wall radially offers threaded hole 31, and rotation stop screw 32 is equipped in threaded hole 31, and cylinder body 1 is interior axially to offer rotation stop along cylinder body 1
Slot 18, rotation stop groove 18 are connected to punched out 12, and the tail portion of rotation stop screw 32 is located in rotation stop groove 18, when piston rod 3 does axial fortune
When dynamic, rotation stop screw 32 can be slided along rotation stop groove 18, be provided on the end face on cylinder body 1 far from rear cover 5 for covering rotation stop groove
18 deckboard 19, deckboard 19 make rotation stop screw 32 not directly to be exposed to external and damage after covering, and outside
It is more beautiful in sight；1 side wall of cylinder body offers the through hole 7 for being connected to rotation stop groove 18, and interior hexagonal silk plug is provided in through hole 7
71。
As shown in Figure 1,2 side wall of piston offers annular groove 22, piston seal 23 is provided in annular groove 22, piston is close
The section of seal 23 is H-shaped, and the outer wall of piston seal 23 contacts at 1 inner wall of cylinder body, and piston rod 3 protrudes into 21 part of adjustment hole
Side wall offers the 4th embedded groove 35, and bar sealing ring 33, the internal diameter and piston of bar sealing ring 33 are embedded in the 4th embedded groove 35
Bar 3 is close to, and the outer diameter of bar sealing ring 33 is close to 21 hole wall of adjustment hole；The setting of piston seal 23 and bar sealing ring 33 can be
It avoids medium and the medium in second chamber 42 in first chamber 41 mutually to circulate to a certain extent, there is leakproofness preferably to imitate
Fruit, when in first chamber 41 and second chamber 42 being hot runner system, internal temperature is higher, and piston seal 23 is set as cutting
Face is H-shaped, can to a certain extent have expansion space, can avoid due to after 23 expanded by heating of piston seal with cylinder body 1
Frictional resistance between inner wall is larger, and move axially in reciprocal fashion piston 2 can not.1 inner wall of cylinder body offers third embedded groove 16,
Third embedded groove 16 is connected to punched out 12, is provided with front cover sealing ring 17 in third embedded groove 16, front cover sealing ring 17 it is interior
Wall contacts at piston rod 3, the setting of front cover sealing ring 17 can avoid to a certain extent the medium in chamber 4 through piston rod 3 with
Outside slot leakage to cylinder body 1 between cylinder body 1, there is the preferable effect of leakproofness.
When adjusting the stroke of cylinder piston rod 3, first rear cover 5 is disassembled from cylinder body 1, then rotation lock nut 6,
Make locking nut 6 far from piston 2, adjusting tool is inserted into jack 10 then rotary-piston 2, since piston rod 3 is in rotation stop
Will not rotate in a circumferential direction with piston 2 under the restriction effect of screw 32, and under the action of screw thread piston rod 3 by 2 axis of opposing pistons
To movement, make to generate a certain distance between piston rod 3 and piston 2, the stroke distances which is adjusted pass through spiral shell
The distance of 3 stroke adjustment of piston rod can be precisely calculated away from the circle number rotated with piston rod 3.After stroke adjustment distance determines,
Locking nut 6 is tightened to 2 direction of piston, the relative position of piston rod 3 is fixed, due to spiral shell between piston rod 3 and piston 2
Line connection, when piston 2 moves axially in reciprocal fashion, 3 opposing pistons 2 of piston rod are fixed and do back and forth along axial direction together with piston 2
Movement, when piston rod 3 drives rotation stop screw 32 to slide along rotation stop groove 18, rotation stop groove 18 can play circumferential limitation to piston rod 3
Effect.It is installed on cylinder body 1 after the completion of the stroke adjustment of piston rod 3, then by rear cover 5, locking nut 6 is made to be located at the first chamber
In room 41.When installing rotation stop screw 32, first piston rod 3 is put into punched out 12, and is made at through hole 7 and threaded hole 31
In coaxial position, rotation stop screw 32 can be so installed in threaded hole 31 by through hole 7, be installed more convenient.It will adjust
The locking nut 6 of 3 stroke of piston rod is installed on inside cylinder body 1, and the axial space not only taken up is smaller, and leakproofness is preferable.
It will pass through hole 7 using interior hexagonal silk plug 71 in 7 aperture of through hole to block, can prevent worker's maloperation from making cylinder can not normal work
Make.In addition, piston rod 3 can opposing pistons 2 carry out bidirectional modulation, when piston rod 3 to far from piston 2 direction adjust when, piston
The total kilometres of bar 3 are elongated, and when adjusting when piston rod 3 to the direction close to piston 2, the total kilometres of piston rod 3 shorten.
As depicted in figs. 1 and 2, one end end face that piston rod 3 is located at punched out 12 is provided with fixing buckle 34, passes through fixing buckle
34 can be connected to external equipment on piston rod 3, offer cooling water pipeline 8 in cylinder body 1, cooling water pipeline 8 circumferentially around in
Fixing buckle 34, the both ends of cooling water pipeline 8 are respectively communicated in cooling water inlet 81 and cooling water outlet 82.It is hot when being used in cylinder
When flow passage system, temperature is higher at fixing buckle 34, makes the temperature of piston rod 3 higher in conductive process, the front cover of rubber material
Sealing ring 17, which will be hardened, makes sealing effect that will be deteriorated, and after being passed through cooling water, cooling effect to a certain extent can be played, before making
The sealing effect of lid sealing ring 17 protects preferable state always.
It should be noted that since the present invention is and then to carry out regulating piston by the position of regulating piston 2 and piston rod 3
The formation of bar 3, so that the present invention in actual implementation, according to the difference of 3 relative position of piston rod, can be such that piston rod 3 realizes
Two-way travel adjusts or the effect of unidirectional (stretching) stroke adjustment.
Embodiment two:
A kind of adjustable cylinder of stroke, as shown in figure 5, the present embodiment and above-described embodiment the difference is that: rear cover 5 passes through
Screw thread is installed on one end on cylinder body 1 far from punched out 12, and one end far from chamber 4 axially offers fabrication hole 51 on rear cover 5,
When rear cover 5 is installed on cylinder body 1, it will adjust in tool insertion process hole 51, then threadingly rotate rear cover 5,
It stops rotating, rear cover 5 can be mounted on cylinder body 1 when rear cover 5 contacts on step 15, when rear cover 5 is torn open from cylinder body 1
It is same adjusting tool to be only inserted in fabrication hole 51 when unloading down, rear cover 5 is then threadingly rotated, makes rear cover 5 to separate
Step 15 moves, and can unload rear cover 5 from cylinder body 1, operates more convenient.
