Abstract
The utility model relates to a mechanical product, in particular to a novel oil cylinder which has the advantages of long service life and automatic reversing. The novel oil cylinder consists of a piston rod, an oil cylinder, an automatic reversing valve and a housing, wherein the piston rod is connected with the oil cylinder; the front end of the piston rod is connected with a bearing ring; the top end of the piston ring is connected with a bearing ring fixing seat; the hydraulic oil cylinder is welded with the automatic reversing valve into a whole; the automatic reversing valve is provided with four oil inlet and return holes, of which two are connected with an oil pressure control device through two external oil pipes, one is connected with the upper part of the oil cylinder through an external oil pipe and one leads to a chamber of the oil cylinder. The novel oil cylinder has the beneficial effects of integrating reversing and oil inlet and return into a whole, reducing exposed pipe joints, reducing maintenance cost, prolonging the service life of the oil cylinder and making mounting and use simple.
Description
Technical field
The utility model relates to a kind of engineering goods, relates in particular to a kind of long service life, auto reversive novel oil cylinder.
Background technique
At present; Upset in industrial machinery and farm machinery, steering equipment have adopted comparatively mostly, and the labour-saving hydraulic jack is used as power; The conventional hydraulic oil cylinder is to adopt oil cylinder is connected through pipeline with oil pressure control system, and the turnover of manual control pressure oil commutates, so troublesome poeration; Along with science and technology development; The appearance of automatic diverter valve, the technician is connected through automatic diverter valve oil cylinder and has realized automatic upset or auto-steering function with oil pressure control system, long-term practice is found: on the automatic reverse valve body, have four be interconnected advance, spill port; Wherein two advance, spill port is connected with oil pressure control system through external oil pipe, other two oilholes pass through external oil pipe and are connected with oil cylinder.This Placement has formed the more pipe joint that exposes and since expose pipe joint receive big pressure effect be easy to generate break, water clock, increase maintenance cost and cost of production.
Summary of the invention
The utility model is to above deficiency, and it is one that a kind of collection switching-over oil inlet and oil return is provided, and reduces and exposes pipe joint, reduction maintenance cost, prolongation oil cylinder working life and install and use simple auto reversive novel oil cylinder.
The utility model solves the technological scheme that its technical problem adopted:
A kind of novel oil cylinder is made up of piston rod, oil cylinder, automatic diverter valve, cover, and piston rod is connecting oil cylinder; The piston rod front end is connected with bearer ring, is connected with the bearer ring fixed base on the piston rod top, and hydraulic jack and automatic diverter valve are welded as a whole; Automatic diverter valve has four oil inlet and oil return holes; Have two to be connected with hydraulic pressure control device through external oil pipe, one is passed through external oil pipe and is connected a straight-through cylinder chamber with oil cylinder top.
Described cover covers the piston rod top, and cover is processed with rubber material, can stretch along with piston rod moves.
Two oil inlet holes of automatic diverter valve are connected with external oil inlet pipe through filter, and external oil inlet pipe is connected with hydraulic pressure control device.
The beneficial effect of the utility model is: collection switching-over oil inlet and oil return is an one, reduces to expose pipe joint, reduction maintenance cost, prolongation oil cylinder working life and install and use simple.
