Abstract
The utility model relates to a pneumatic cylinder sealing ring channels into structure, including piston rod, high -pressure hydraulic pressure cylinder body, sealing washer guide pin bushing and O type sealing washer, the drive installation of piston rod direction is in the mounting hole that the high -pressure hydraulic pressure body of rod make, and coaxial cover is equipped with a sealing washer guide pin bushing outside the piston rod of this mounting hole tip, in the middle part of the inner circle of sealing washer guide pin bushing with the piston rod between coaxial pressure equipment have a O type sealing washer, the inner circle port system of sealing washer guide pin bushing has the cross -section to be the guide groove on back taper inclined plane, the coaxial pressure equipment of inner circle port of sealing washer guide pin bushing have one with guide groove shape complex J type sealing washer. This strutting arrangement simple structure, convenient operation, low cost, the installation of being convenient for avoids the accessory be injured and promote work efficiency.
Description
Technical field
The utility model belongs to machining equipment field, especially a kind of hydraulic cylinder sealing ring guiding structure.
Background technique
In order to ensure the sealing in use, the seal ring of the piston rod of high pressure liquid cylinder pressure needs to bear larger pressure, the resistance born when mounted is also very large, cause installation comparatively difficult, need during installation to use larger pressure or knock continuously, once exert a force excessively can cause the problems such as damage, distortion again.
Model utility content
The purpose of this utility model is to overcome the deficiencies in the prior art part, provides that a kind of structure is simple, easy to operate, with low cost, the hydraulic cylinder sealing ring guiding structure of long service life.
The utility model solves its technical problem and takes following technological scheme to realize:
A kind of hydraulic cylinder sealing ring guiding structure, comprise piston rod, high-pressure and hydraulic cylinder body, seal ring guide pin bushing and O RunddichtringO, the drive installation of piston rod guiding is in the made mounting hole of the high-pressure and hydraulic body of rod, the outer coaxial sleeve of piston rod in this mounting hole end is equipped with a seal ring guide pin bushing, an O RunddichtringO is coaxially pressed with in the middle part of the inner ring of seal ring guide pin bushing and between piston rod, it is characterized in that: the inner ring port of described seal ring guide pin bushing is shaped with the guiding groove that cross section is inverted cone inclined-plane, a J RunddichtringO coordinated with guiding bevel shape is coaxially pressed with at the inner ring port of seal ring guide pin bushing.
And described seal ring guide pin bushing interference fit is arranged in annular groove made on high-pressure and hydraulic cylinder body and the end face of seal ring guide pin bushing flushes with the outer surface of high-pressure and hydraulic cylinder body.
And multiple positioning screwns that seal ring is installed by radial equipartition are packed on high-pressure and hydraulic cylinder body.
Advantage of the present utility model and good effect are:
This support device structure is simple, easy to operate, with low cost, is convenient to install, and avoids accessory injured and promotes working efficiency.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model;
Fig. 2 is seal ring guide pin bushing structure for amplifying schematic diagram.
In accompanying drawing, mark represents: 1-piston rod, 2-J RunddichtringO, 3-O RunddichtringO, 4-positioning screwn, 5-seal ring guide pin bushing, 6-high-pressure and hydraulic cylinder body, 7-guides groove.
Embodiment
Below in conjunction with accompanying drawing, also by specific embodiment, the utility model is described in further detail, and following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
A kind of hydraulic cylinder sealing ring guiding structure, comprise piston rod 1, high-pressure and hydraulic cylinder body 6, seal ring guide pin bushing 5 and O RunddichtringO 3, the drive installation of piston rod guiding is in the made mounting hole of the high-pressure and hydraulic body of rod, the outer coaxial sleeve of piston rod in this mounting hole end is equipped with a seal ring guide pin bushing, and sealing circle guide pin bushing interference fit is arranged in annular groove made on high-pressure and hydraulic cylinder body and the end face of seal ring guide pin bushing flushes with the outer surface of high-pressure and hydraulic cylinder body; Seal ring is packed on high-pressure and hydraulic cylinder body by multiple positioning screwns 4 that radial equipartition is installed; An O RunddichtringO is coaxially pressed with in the middle part of the inner ring of seal ring guide pin bushing and between piston rod.
Innovative point of the present utility model is:
The inner ring port of described seal ring guide pin bushing is shaped with the guiding groove 7 that cross section is inverted cone inclined-plane, and the effective erection & lift of this improvement is convenient; Coaxially be pressed with a J RunddichtringO 2 coordinated with guiding bevel shape at the inner ring port of seal ring guide pin bushing, ensure the sealing of inner ring port.
Although disclose embodiment of the present utility model and accompanying drawing for the purpose of illustration, but it will be appreciated by those skilled in the art that: in the spirit and scope not departing from the utility model and claims, various replacement, change and amendment are all possible, therefore, scope of the present utility model is not limited to the content disclosed in embodiment and accompanying drawing.
