Description

A kind of pair of rod high-voltage oil cylinder end cap
Technical field
The utility model is applied to high-pressure injection pump field, especially a kind of pair rod high-voltage oil cylinder end cap.
Background technology
Hydraulic cylinder be hydraulic energy is changed into mechanical energy, the hydraulic pressure that does straight reciprocating motion (or oscillating motion) performs member Part.Its simple in construction, reliable operation.Realized with it during reciprocating motion, deceleration device can be removed from, and without drive gap, Stable movement, therefore be used widely in various mechanical hydraulic systems.Double rod hydraulic jacks can be saved with two-way work doing Save workpiece, raising efficiency, bilateral end cap will loading piston bar pressure-operated, under long-time high-pressure work state, easily There is abrasion, the situation of oil leak, and be difficult to maintenance recovery, influence output pressure and job stability.
Utility model content
The purpose of this utility model is to overcome in place of the deficiencies in the prior art that there is provided a kind of pair of rod hydraulic oil cylinder end Lid, using metal structure as rack body, strengthens service life, mitigates abrasion.
The utility model solves its technical problem and takes following technical scheme to realize:
A kind of pair of rod high-voltage oil cylinder end cap, including end cover body 1, piston rod mounting hole and through hole, end cap are used for solid Mounted in axial one end of cylinder body, coaxially a piston rod mounting hole is formed with the middle part of end cover body;End in piston rod mounting hole periphery Cover and be formed with multiple through holes, it is characterised in that:
Middle part is formed with a sealing bulge loop in piston rod mounting hole, between sealing bulge loop and the cylinder interior end face of end cap The radial direction side of end cap be formed with an oil filler point, oil filler point connection piston rod mounting hole is formed with interior spiral shell on the outside of the oil filler point Line, which is used to engage, installs oiling pipe joint;
Filler annular groove is formed between sealing bulge loop and the outer face of end cap, is formed between the filler annular groove and sealing bulge loop 45 ° of inclined-plane, the piston rod mounting hole between filler annular groove and end cap end face is formed with a circular end plate mounting groove, the end plate Mounting groove diameter is more than filler annular groove;45 ° of transition rings are formed between filler annular groove and end plate mounting groove.
Moreover, end cover body is square stereochemical structure, the end face for being embedded in valve body in end cover body is formed with the cylinder of cylinder Inner sleeve, the end cover body link position in sleeve pipe with root is formed with a coaxial insertion annular groove, the corresponding cylinder body of insertion annular groove Axial end is formed with embedded bulge loop.
Moreover, annular seal groove is formed with the middle part of the annular outer wall of inner cylinder sleeve pipe, mounting O-shaped rings in the annular seal groove.
Advantage of the present utility model and good effect are:
The utility model reasonable in design, composition is simple and reliable, and low cost, fault rate are low, be easy to safeguard, it is ensured that sealing Property on the premise of lifting activity flexibility, mitigate abrasion, and service life is long, from the functional reliability and entirety of lift elements Service life.
Brief description of the drawings
Fig. 1 is half-sectional structural representation of the present utility model;
Fig. 2 is this Fig. 1 overall left view.
Embodiment
Below in conjunction with the accompanying drawings and the utility model is described in further detail by specific embodiment, following examples are to retouch The property stated, be not limited, it is impossible to limit protection domain of the present utility model with this.
A kind of pair of rod high-voltage oil cylinder end cap, including end cover body 1, piston rod mounting hole (non-label) and through hole 9, end Cover in the middle part of axial one end for being packed in cylinder body, end cover body and be coaxially formed with a piston rod mounting hole;In piston rod mounting hole Multiple through holes 9 are formed with the end cap of periphery, for end cap to be packed in into cylinder ends.
Piston rod stretches out end cap by the piston rod mounting hole of end cover body, and it is past to carry out straight line in hydraulic oil driving lower piston rod Multiple motion.
Innovative point of the present utility model is:
In piston rod mounting hole middle part be formed with a sealing bulge loop 6, sealing bulge loop and end cap cylinder interior end face it Between the radial direction side of end cap be formed with an oil filler point 2, oil filler point connection piston rod mounting hole injects pressure oil in cylinder body; On the outside of the oil filler point be formed with internal thread be used for engage installation oiling pipe joint;
In order to mitigate the hard friction of end cap and piston rod, packing ring is formed between sealing bulge loop and the outer face of end cap Groove 7, is formed with the stiff dough contact surface on 45 ° of inclined-plane, further less end cap and piston rod between the filler annular groove and sealing bulge loop Product;Piston rod mounting hole between filler annular groove and end cap end face is formed with a circular end plate mounting groove 8, the end plate mounting groove Diameter is more than filler annular groove;45 ° of transition rings are formed between filler annular groove and end plate mounting groove.
For the ease of installing, this end cover body is square cover plate, is easy to make oil filler point and the valve body oiling of end plate main body Hole installation site proper alignment.
In order to lift being completely embedded for end cover body and valve body, the end face of the end cover body insertion valve body is formed with cylinder Inner cylinder sleeve pipe 3, the end cover body link position in sleeve pipe with root is formed with a coaxial insertion annular groove 5, embedded annular groove correspondence Cylinder body axial end be formed with embedded bulge loop.
In order to ensure the sealing between end cover body and cylinder body, annular is formed with the middle part of the annular outer wall of inner cylinder sleeve pipe close Mounting O-shaped rings in sealing groove 4, the annular seal groove.
Although disclosing embodiment of the present utility model and accompanying drawing for the purpose of illustration, those skilled in the art can be with Understand:Do not departing from the utility model and spirit and scope of the appended claims, it is various replace, change and modifications all be can Can, therefore, scope of the present utility model is not limited to embodiment and accompanying drawing disclosure of that.
