Abstract
The utility model relates to a reciprocating motion working table adopting a hydraulic system as driving power. The upper part of the reciprocating motion working table is a working table-board; the hydraulic system used for driving the working table to do the reciprocating motion is arranged below the working table-board; at least one horizontal difunctional hydraulic cylinder is arranged in the hydraulic system; a vertical connecting rod is arranged below the working table-board; one end of the vertical connecting rod is fixedly connected with the working table-board, and the other end of the vertical connecting rod is fixedly connected with a free end of a piston rod of the difunctional hydraulic cylinder; hydraulic fluid ports are arranged at two ends of the difunctional hydraulic cylinder, and are communicated with a reversing valve communicated with an oil tank through an oil pump; an oil filter is arranged at the outlet of the oil tank; when the reversing valve is positioned in the mesoposition, the hydraulic system unloads; when the reversing valve is positioned in a first station, oil enters from one end of the difunctional hydraulic cylinder and exists from the other end of the difunctional hydraulic cylinder; when the reversing valve is positioned in a second station, the oil inlet end and the oil outlet end of the difunctional hydraulic cylinder are opposite to the oil inlet end and the oil outlet end of the difunctional hydraulic cylinder, which is positioned in the first station. The reciprocating motion working table can maintain the balance and the stability of the reciprocating motion of the whole working table-board, and generates a low noise.
Description
Technical field
The utility model relates to a kind of workbench, and specifically, relating to a kind of is the reciprocating motion workbench of driving force with hydraulic pressure.
Background technology
In the prior art, the common type of drive that moves back and forth workbench has Mechanical Driven modes such as gear drive, chain wheel drive, but these type of drive are often followed certain noise and vibrations, in the reciprocating process of workbench, can produce shake, and is not too safe.And hydraulic machinery becomes one of a kind of preferred type of drive that moves back and forth workbench with advantages such as its load are big, driving is steady, noise is low.Based on this mentality of designing, it is the reciprocating motion workbench of driving force by hydraulic system that the utility model is intended to design a kind of.
The utility model content
The purpose of the utility model is to overcome the deficiency of prior art, and a kind of reciprocating motion workbench is provided.
In order to realize the purpose of the utility model, the technical scheme that the utility model adopts is:
A kind of reciprocating motion workbench, top are work top, and the work top below is provided with and is used to drive the reciprocating hydraulic system of workbench; The double acting hydraulic cylinder of at least one level is set in the said hydraulic system, and said work top below is provided with vertical connecting rod, and vertically an end of connecting rod is fixedly connected with work top; The other end is fixedly connected with the free end of the piston rod of double acting hydraulic cylinder, and the two ends of double acting hydraulic cylinder are provided with hydraulic fluid port, and hydraulic fluid port is communicated with reversal valve; Reversal valve is communicated with fuel tank through oil pump, and the fuel-tank outlet place is provided with oil filter, when said reversal valve is in meta; The hydraulic system off-load; When reversal valve was in first station, double acting hydraulic cylinder one end oil-feed, the other end were fuel-displaced, and the oil-feed of double acting hydraulic cylinder when reversal valve is in second station, oil outlet end are opposite with first station.
