Abstract

The invention provides a double-support structure of a hydraulic oil tank. The double-support structure comprises a low-pressure shell (1), a low-pressure piston (2), a high-pressure piston (4), a high-pressure shell (5) and a support cover (3); the low-pressure shell (1) is in a through structure; the low-pressure piston (2) and the high-pressure piston (4) are fixedly connected to form a moving unit which performs piston reciprocation in the low-pressure shell (1) and the high-pressure shell (5); the support cover (3) covers one end of the low-pressure shell (1); the center of the support cover (3) is provided with an opening; the high-pressure shell (5) is in a through structure fixedly connected to the opening of the support cover (3); a body of the high-pressure piston (4) is disposed within the high-pressure shell (5); the low-pressure shell (1) supports the low-pressure piston (2); the support cover (3) and the high-pressure shell (5) support the high-pressure piston (4). The double-support structure has the advantages that eccentric wear is greatly decreased, wear of sealing parts is reduced, and service lives of products can be prolonged.

Description

A kind of hydraulic oil container dual-support structure
Technical field
The invention belongs to mechanical design field, relate to a kind of hydraulic oil container dual-support structure.
Background technique
As shown in Figure 1, it is a kind of existing hydraulic oil packing list supporting structure.Low-pressure shell 1 and high pressure piston 4 are connected as fixed support assembly, and High Pressure Shell 5 and low pressure piston 2 are connected as mobilizing exercises assembly.Low-pressure shell 1 only at low pressure piston 2 place for mobilizing exercises assembly provide one place support, under normal completely oil condition, High Pressure Shell 5 is stretched out completely, form single armed suspension beam structure, High Pressure Shell 5 gravitational moment impact under to kinematic pair particularly high pressure piston 4 piston part Sealing cause eccentric wear, cause Sealing easily to lose efficacy and cause leakage, reduce product working life; Low-pressure shell 1 is major diameter blind hole structure simultaneously, and difficulty of processing is high, and the morpheme requirement of shell inner hole etc. are difficult to reach designing requirement from everyways such as technique, processing and inspections.
Summary of the invention
The object of the invention is: provide a kind of and eliminate single armed overarm impact, reduce eccentric wear to sealing part abrasion, improve working life, be easy to the dual-support structure processed.
Technical solution of the present invention provides a kind of hydraulic oil container dual-support structure, comprise low-pressure shell 1, low pressure piston 2, high pressure piston 4, High Pressure Shell 5, it is characterized in that, also comprise supporting cover 3, described low-pressure shell 1 is communicating structure, described low pressure piston 2 is connected as mobilizing exercises assembly with high pressure piston 4, reciprocating motion of the pistons can be done in low-pressure shell 1 with High Pressure Shell 5, described supporting cover 3 covers in described low-pressure shell 1 one end, there are an opening in central authorities, described High Pressure Shell 5 is communicating structure, be connected in the opening of described supporting cover 3, the piston part of described high pressure piston 4 is in described High Pressure Shell 5, low-pressure shell 1 for low pressure piston 2 provide one place support, supporting cover 3 and High Pressure Shell 5 provide a place to support for high pressure piston 4.
Preferably, described supporting cover 3 there is the hydraulic fluid port be communicated with oil circuit.
Preferably, low-pressure shell 1 and supporting cover 3 end face seal, screw screws up fastening.
Preferably, High Pressure Shell 5 and supporting cover 3 end face seal, screw screws up fastening.
Advantage of the present invention is: this dual-support structure is that mobilizing exercises assembly increases a strong point at supporting cover place, change the single armed suspension beam structure in single supporting structure, eliminate the impact of gravitational moment in single supporting structure, significantly reduce the generation of eccentric wear phenomenon, reduce the wearing and tearing of Sealing, be beneficial to the operating life extending product; Low-pressure shell is through-hole structure simultaneously, and difficulty of processing will reduce greatly, improve manufacturability and the Economy of Product processing.
Accompanying drawing explanation
Below accompanying drawing of the present invention is described:
Fig. 1 is a kind of existing hydraulic oil packing list supporting structure schematic diagram, and wherein 1 is low-pressure shell, and 2 is low pressure pistons, and 4 is high pressure pistons, and 5 is High Pressure Shell;
Fig. 2 is hydraulic oil container dual-support structure schematic diagram of the present invention, and wherein 1 is low-pressure shell, and 2 is low pressure pistons, and 3 is supporting covers, and 4 is high pressure pistons, and 5 is High Pressure Shell.
Embodiment
Below by specific embodiment, the present invention is described further:
Refer to Fig. 2, it is hydraulic oil container dual-support structure schematic diagram of the present invention.Low-pressure shell 1, supporting cover 3 are connected as fixed support assembly with High Pressure Shell 5, and low pressure piston 2 and high pressure piston 4 are connected as mobilizing exercises assembly.Low-pressure shell for low pressure piston provide one place support, supporting cover for high pressure piston provide one place support.Low-pressure shell and supporting cover end face seal, screw screws up fastening.High Pressure Shell and supporting cover end face seal, screw screws up fastening.Low-pressure shell is through-hole structure.
The present invention has abandoned the single supporting structure in the past adopted, be that mobilizing exercises assembly increases a strong point by supporting cover, change the single armed suspension beam structure in single supporting structure, eliminate the impact of gravitational moment in single supporting structure, significantly reduce the generation of eccentric wear phenomenon, reduce the wearing and tearing of Sealing, be beneficial to the operating life extending product; Low-pressure shell is through-hole structure simultaneously, and difficulty of processing will reduce greatly, improve manufacturability and the Economy of Product processing.
