Description
[technical field]
The present invention relates to a kind of fluid pressure actuating unit, particularly relate to the oil tank device in a kind of force standard machines hydraulic control.
[background technique]
Force value is indispensable important physical amount in industrial and agricultural production, national defense construction and scientific research, the amount of capacity of force standard machines and the height of metrological performance level are the important symbols of the national industry of reflection one, national defence and field of scientific study Strategic Competition power.The range of domestic common large force standard machines is 30MN, is all to utilize hydraulic jack ouput force to drive associated components work, and the oil cylinder structure of hydraulic of force standard machines is single cylinder structure.
Along with domestic industry is produced and scientific and technical development, increasing to the measurement demand of great force value, therefore need to set up larger force value disjunction mark accurate, to meet the needs of state aviation aerospace industry, nuclear power, metallurgy, machinery and large bridge building development, the applicant have developed the force standard machines that a kind of range is 60MN, the force standard machines of great force value is according to single cylinder structure, then cylinder diameter is very large, and needed for 60MN force standard machines, cylinder diameter is about 1600mm.But the current domestic machine producing so major diameter oil cylinder is little, there is difficulty of processing very large, the problem that cost of production is high, and the oil cylinder of so large volume is very high to the requirement of its hydraulic servo control system.
Therefore, 60MN force standard machines adopts oil cylinder centered by master cylinder, the oil cylinder structure of hydraulic of a plurality of auxiliary oil cylinder setting of evenly arrangement around master cylinder, as shown in Figure 1, this oil cylinder structure of hydraulic 100 can not only make the lower bearing plate uniform force of force snesor, and then makes the detection indicating value of force snesor accurate.But its technological difficulties are: ensure the oil-feed simultaneously of master cylinder and auxiliary oil cylinder and oil pressure is consistent, the height that rises of each oil cylinder is consistent like this, and the bearing plate above oil cylinder keeps level, guarantee force standard machines detection data accurate, reliable.
In view of this, the present inventor furthers investigate for the defect of prior art, then has this case to produce, between hydraulic control device and oil cylinder, namely set up this invention oil tank device.
[summary of the invention]
Technical problem to be solved by this invention is to provide the oil tank device in a kind of force standard machines hydraulic control, is arranged between hydraulic control device and hydraulic jack, makes hydraulic oil enter master cylinder and auxiliary oil cylinder and isostasy simultaneously.
The present invention is achieved in that
Oil tank device in force standard machines hydraulic control, comprises an Oil Tank Body, and described Oil Tank Body one end has gland; Oil storage tank supporting frame is established to support bottom described Oil Tank Body; Described oil storage tank supporting frame is provided with oil storage tank fixing clamp, for fixing Oil Tank Body;
Described Oil Tank Body is provided with the consistent oil outlet of a plurality of height, and this oil outlet connected pipes is to each oil cylinder of force standard machines;
There is bottom described Oil Tank Body oil inlet hole and spill port, described oil inlet hole is provided with one-way valve, described spill port is arranged zero pressure release pressure retaining valve; Described oil inlet hole is connected with fuel tank through hydraulic servo control apparatus by oil pipe with spill port.
Further, described oil outlet comprises large aperture first oil outlet being positioned at described Oil Tank Body both sides and small aperture second oil outlet be positioned in the middle part of described Oil Tank Body; Described first oil outlet is connected to master cylinder; Described second oil outlet is connected to auxiliary oil cylinder.
The invention has the advantages that: on the one hand, hydraulic oil enters master cylinder and auxiliary oil cylinder simultaneously, and pressure is consistent, ensures the bearing plate level above oil cylinder, thus ensures that force standard machines detects the accurate, reliable of data; On the other hand, oil return speed is accelerated, and shortens force standard machines unloading consuming time, thus improves force standard machines working efficiency.
[accompanying drawing explanation]
The invention will be further described in conjunction with the embodiments with reference to the accompanying drawings.
Fig. 1 is the cylinder structure schematic diagram of force standard machines.
Fig. 2 is perspective view of the present invention.
Fig. 3 is sectional view of the present invention.
[embodiment]
As shown in Figures 2 and 3, the oil tank device in force standard machines hydraulic control, comprises an Oil Tank Body 1, and described Oil Tank Body 1 one end has gland 2; Oil storage tank supporting frame 4 is established to support bottom described Oil Tank Body 1; Described oil storage tank supporting frame 4 is provided with oil storage tank fixing clamp 3, for fixing Oil Tank Body 1.
Oil Tank Body 1 both sides are respectively equipped with large aperture first oil outlet 51, and be provided with 12 small aperture second oil outlet 52, first oil outlets 51 in the middle part of Oil Tank Body 1 all consistent with the height of the second oil outlet 52, the first oil outlet 51 is connected to master cylinder; Second oil outlet 52 is connected to auxiliary oil cylinder.
There are bottom Oil Tank Body 1 two oil inlet holes 61 and six spill ports 62, oil inlet hole 61 is provided with one-way valve (not shown), spill port 62 is arranged zero pressure release pressure retaining valve (not shown); Oil inlet hole 61 is connected with fuel tank through hydraulic servo control apparatus by oil pipe with spill port 62.Pressure gauge (not shown) is also equipped with at oil storage tank 1 top.
Hydraulic control device controls entering of oil cylinder, oil return, specific works process is: under the effect of hydraulic servo control system, during loading, the selector valve of oil inlet hole is opened, the hydraulic oil of fuel tank enters oil storage tank by hydraulic control device, when hydraulic oil reaches the oil outlet of oil storage tank, continue oil-feed, under pressure, hydraulic oil enters each oil cylinder, the oil pipe of the same length is set from oil outlet to hydraulic jack, like this, hydraulic oil enters each oil cylinder simultaneously and pressure is consistent, ensure bearing plate level above oil cylinder, thus it is accurate to ensure that force standard machines is measured, reliably, during unloading, zero pressure release pressure retaining valve of spill port is opened, and the hydraulic oil of oil storage tank is through hydraulic control device oil return to fuel tank, and oil pressure declines, and the hydraulic oil oil return in oil cylinder, to oil storage tank, accelerates oil return speed greatly, improves the working efficiency of force standard machines.
Beneficial effect of the present invention is: on the one hand, and hydraulic oil enters master cylinder and auxiliary oil cylinder simultaneously, and pressure is consistent, ensures the bearing plate level above oil cylinder, thus ensures that force standard machines detects the accurate, reliable of data; On the other hand, oil return speed is accelerated, and shortens force standard machines unloading consuming time, thus improves force standard machines working efficiency.
The foregoing is only better enforcement use-case of the present invention, be not intended to limit protection scope of the present invention.Field of hydraulic control, similar oil pressure balance device, all at this protection domain, is not confined to force standard machines, within the spirit and principles in the present invention all, and any amendment done, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
