Abstract
The utility model discloses a synchronization distributor hydraulic cylinder which comprises a plurality of cylinder barrels. Every two cylinder barrels are connected through a connecting flange. A piston rod is arranged in each cylinder barrel. A piston is arranged on the end portion of each piston rod in a sleeved mode. Two small holes are drilled in the side wall of each cylinder barrel. A flow guiding groove is milled in the outer wall, between the two small holes, of each cylinder barrel. A flow guiding block is arranged on each flow guiding groove. The periphery of each flow guiding block is welded with each cylinder barrel tightly. A flow guiding hole is formed in each piston. The synchronization distributor hydraulic cylinder is used for a mechanism which needs multi-cylinder synchronization in a hydraulic system, synchronization accuracy is high and can reach 0.5%, structure is simple, cost is low, and synchronization accuracy of the system is not affected by various factors such as pressure, flow and load of the system.
Description
Technical field:
The utility model relates to hydraulic equipment field, specifically a kind of synchronous distributor oil hydraulic cylinder.
Background technique:
Drive simultaneously at a plurality of linear hydraulic final controlling element, and in hydraulically powered jumbo field was arranged, as crane gear and steel rolling mill, the simultaneously operating of a plurality of stand under load hydraulic actuators was to its performance important.And the continuous motion time is longer, and synchronization error can be cumulative.The closed loop synchronization hydraulic system that the usage ratio servo techniques is controlled, synchronization accuracy can reach 1 ‰, but corresponding design and manufacture cost is also very high.Now imagine a kind of synchronous distributor oil hydraulic cylinder, can reach very high synchronization accuracy again when reducing costs, and can automatically eliminate synchronization error.
The model utility content:
The utility model provides a kind of synchronous distributor oil hydraulic cylinder, can eliminate the synchronization error of bringing because of reasons such as leakages, its principle is to utilize a plurality of volume oil pockets to a plurality of oil cylinder fuel feeding, guarantees synchronously with fuel delivery, eliminates synchronization error by being welded with baffle in the cylinder barrel outside.
The technical solution adopted in the utility model:
A kind of synchronous distributor oil hydraulic cylinder, it is characterized in that: include a plurality of cylinder barrels, cylinder barrel connects by adpting flange between any two, be provided with piston rod in each cylinder barrel, the end of piston rod is set with piston, is drilled with two apertures on the sidewall of cylinder barrel, be milled with guiding gutter on the outer wall of the cylinder barrel between two apertures, guiding gutter is provided with baffle, and between the surrounding of baffle and cylinder barrel, tightly welding, be drilled with pod apertures on described piston.
Described a kind of synchronous distributor oil hydraulic cylinder, it is characterized in that: the diameter of described all pistons, stroke and speed are identical, and the diameter of all piston rods is identical.
Described a kind of synchronous distributor oil hydraulic cylinder is characterized in that: the length of described baffle is determined according to the thickness of piston.
Baffle can be when oil hydraulic cylinder arrives the position of upper dead center or lower dead centre, two-way automatic elimination synchronization error.
The utility model has the advantages that:
The utility model is used for the mechanism that hydraulic system requires multi-cylinder synchronous, and synchronization accuracy is high, can reach 5 ‰, and simple in structure, cost is low, and the synchronization accuracy of system is not subjected to the impact of the various factorss such as pressure, flow and load of system.
Description of drawings:
Fig. 1 is structural representation of the present utility model.
Embodiment:
as shown in Figure 1, a kind of synchronous distributor oil hydraulic cylinder, the many piston hydraulic cylinders of many piston rods, include a plurality of cylinder barrels 1, cylinder barrel 1 connects by adpting flange 8 between any two, be provided with piston rod 2 in each cylinder barrel 1, the end of piston rod 2 is set with piston 3, stroke and the speed of all pistons 3 are identical, all piston 3 diameters, piston rod 2 diameters are identical, therefore each chamber discharge capacity is identical, respectively be drilled with two apertures 4 by certain distance on cylinder barrel, cylinder barrel 1 outside is welded with baffle 5, the length of baffle 5 is determined according to the thickness of piston 3, baffle 5 welds front inside and first mills into a guiding gutter 6, baffle 5 surroundings and cylinder barrel 1 welding are tight, leakage must not be arranged, be drilled with pod apertures 7 on piston 3.Baffle 5 can be when oil hydraulic cylinder arrives the position of upper dead center or lower dead centre, two-way automatic elimination synchronization error.
