Specific implementation mode
The utility model is explained in detail below in conjunction with the accompanying drawings.
A kind of adjustable lubricating cup of pressurized cylinder high pressure oil as shown in Figure 1, including cup body 1,1 both ends of cup body protecgulum 2 with after
Lid 3, the cup body 1, protecgulum 2 combine to form oil storage cavity 4 with rear cover 3, and piston 5 is arranged in the oil storage cavity 4, living
Plug 5 divides oil storage cavity 4 for two parts, and two-part volume can be changed with the movement of piston 5,5 top of piston
It is mainly used for storing gas, 5 lower part of piston is mainly used for storing high-voltage oil liquid；Hydraulic fluid port 6 and oil storage are equipped on the rear cover 3
Cavity 4 is connected to, and is connected to oil storage cavity 4 equipped with gas port 7 on the protecgulum 2, and hydraulic fluid port 6 is both designed as L-type with gas port 7,
Import is located at protecgulum 2, and either its outlet is on the side of protecgulum 2 or rear cover 3 on the inner face of rear cover 3, this design method
Facilitate and fixes and facilitate installation oil circuit and gas circuit；Elastomer, the bullet of this programme are equipped between the protecgulum 2 and piston 5
Property body using spring 12 make, be not merely limited to spring 12, as long as elastic effect can be played, piston 5 enabled to exist
It realizes and moves back and forth in cup body 1 under the promotion of fluid；One sleeve 8, the sleeve 8 are set on the protecgulum 2
It is connected to oil storage cavity 4, one nut 9, the appearance of the inner surface and sleeve 8 of the nut 9 is set in 8 outside of sleeve
Face is connected through a screw thread, and a mandrel 10 is equipped in the nut 9；Described elastomer one end is against on piston 5, the other end
It is against the end of mandrel 10.
The operation principle of above structure is that fluid enters the shoe cream room of 5 lower section of piston by the hydraulic fluid port 6 of rear cover 3 first
In body 4, fluid pushes piston 5 to move upwards, and piston 4 compresses spring 12, when the restoring force and oil for being compressed to spring 12
When the pressure of liquid is suitable, piston 5 is not acting, and the stroke of fluid storage capacity and pressurized cylinder is constant at this time；When needing to store up
When oil mass and stroke are changed, by regulating nut 9 so that mandrel 10 moves upwards, spring 12 follows mandrel 10 to transport upwards
Dynamic, so that the position of spring 12 moves up, the stroke of piston 5 will become larger, so that oil reserve becomes larger, pressurized cylinder
Stroke also becomes larger；When needing stroke to become small, regulating nut 9 drives spring 12 to move downward, and reduces oil storage space.
Further its structure is designed, the mandrel 10 includes the pedestal supported with elastomer phase, is located on pedestal
Long axis, described long axis one end is fixed on nut 9, and baffle 11 is inwardly arranged in 8 top of sleeve, in the baffle
11 middle parts are the centre bore passed through for long axis, and the pedestal is less than diameter of the internal diameter more than centre bore of sleeve 8, when pedestal is transported
It will not moved up after moving at baffle 22, and can ensure that nut 9 will not be fallen out, and improve security performance.Meanwhile it is described
Piston 5 be equipped with for retaining spring 12 positioning groove 13, can position of the limited spring 12 on piston 5, do not deviate by.
Further for the leakproofness for ensureing total, sealing is respectively provided between the cup body 1 and protecgulum 2, rear cover 3, piston 5
Circle；10 top of mandrel passes through nut 9 and is fixed by c-type retaining ring, and this structure is easy for installation.
To sum up, after using above structure, the position of spring 12 is adjusted by adjusting the position of nut 9, realizes piston 5
Either the become smaller oil mass of storage of the becoming larger of mobile distance becomes more or tails off, to control the stroke of pressurized cylinder；It is logical
The structure for crossing screw thread facilitates adjusting, and the height that can be controlled to adjust, simple in structure, easy to operate practicality.
It is emphasized that：The above is only the preferred embodiment of the present utility model, not appoints to the utility model
What formal limitation, any simple modification made by the above technical examples according to the technical essence of the present invention, etc.
With variation and modification, it is still within the scope of the technical solutions of the present invention.
