Abstract

A rigid supporting hydraulic cylinder comprises a main cylinder block, wherein an auxiliary cylinder block is connected with the lower end of the main cylinder block, the axis of the main cylinder block and the axis of the auxiliary cylinder block vertically intersect so as to form an L shape, a first oil mouth is arranged at the upper end of the main cylinder block, a second oil mouth is arranged at one end of the auxiliary cylinder block, an auxiliary piston is arranged in the auxiliary cylinder block, the auxiliary piston is located between the main cylinder block and the second oil mouth, more than two steel balls are arranged between the auxiliary piston and a main piston, three through holes which are mutually perpendicular are formed in the diameter direction of an arbitrary steel ball, the bottom face at the lower end of the inner cavity of the main cylinder block is in oblique plane shape, oil is discharged from the first oil mouth of the main cylinder block, the oil is injected into the second oil mouth of the auxiliary cylinder block, oil pressure pushes the auxiliary piston to move towards the main cylinder block, the auxiliary piston transmits pressure to the bottom face of the main piston through hydraulic oil between the auxiliary piston and the main piston, and thereby pushes the main piston to rise, and simultaneously the steel balls are pushed into a space between the main piston and the bottom face of the main cylinder block, and bears pressure applied to the main piston. The rigid supporting hydraulic cylinder can eliminate influences caused by compressibility of liquid.

Description

The oil hydraulic cylinder of rigid support
Technical field:
The utility model relates to mechanical field, relates in particular to hydraulics, particularly a kind of oil hydraulic cylinder of rigid support.
Background technique:
Oil hydraulic cylinder is widely used in industrial production.Wherein, piston rod does straight line motion with respect to cylinder body.In certain applications occasion, require the structure that piston rod supports in space, to there is stability, and can bear the impact of moment.Due to the compressibility of the leakage in hydraulic transmission and liquid, oil hydraulic cylinder of the prior art is difficult to realize above-mentioned requirements.
Summary of the invention:
The purpose of this utility model is to provide a kind of oil hydraulic cylinder of rigid support, and the oil hydraulic cylinder of described this rigid support will solve the compressibility of liquid in prior art and cause oil hydraulic cylinder to be not enough to ensure the stability of bearing structure in space and the technical problem that can bear moment impact.
The oil hydraulic cylinder of this rigid support of the present utility model, comprise a Master cylinder body, in described Master cylinder body, be provided with a main piston and a main piston rod, described main piston rod is coaxial with Master cylinder body, the lower end of main piston rod is connected with described main piston, Master cylinder body is stretched out from the upper end of Master cylinder body in the upper end of main piston rod, wherein, the lower end of described Master cylinder body is connected with a subsidiary cylinder, the axis of the axis of described Master cylinder body and described subsidiary cylinder is L-type and intersects vertically, the upper end of Master cylinder body is provided with first hydraulic fluid port, one end of subsidiary cylinder is provided with second hydraulic fluid port, in subsidiary cylinder, be provided with a sub-piston, described sub-piston is between Master cylinder body and described the second hydraulic fluid port, between sub-piston and main piston, be provided with the steel ball of more than two number, the diameter of the steel ball described in any one is equal to or is slightly less than the internal diameter of Master cylinder body and subsidiary cylinder, in any one steel ball, be all provided with three orthogonal through holes along diametric(al).
Further, the bottom surface, inner chamber lower end of Master cylinder body is inclined-plane.
Working principle of the present utility model is: from the first hydraulic fluid port emptying of Master cylinder body, to oiling in the second hydraulic fluid port of subsidiary cylinder, oil pressure promotes sub-piston and moves to Master cylinder body, sub-piston is by the hydraulic oil between sub-piston and main piston, transfer the pressure to the bottom surface of main piston, promote main piston and rise, simultaneously, steel ball is pushed between main piston and Master cylinder body bottom surface, the pressure that carrying main piston is subject to.
The utility model and prior art are compared, and its effect is actively with obvious.The utility model arranges subsidiary cylinder in one end of oil hydraulic cylinder, utilizes the pressure of steel ball carrying main piston, can ensure the stability of bearing structure in space and can bear moment impact, has eliminated the impact of liquid compressibility.
Brief description of the drawings:
Fig. 1 is the principle schematic of the oil hydraulic cylinder of rigid support of the present utility model.
Fig. 2 is the principle schematic of the working state of the oil hydraulic cylinder of rigid support of the present utility model.
