Abstract
The utility model relates to a following hydraulic chuck power source belonging to filed of material-mechanics testing equipment. An oil-absorbing filter is connected with an oil tank and is connected with an oil pump through a pipeline; a motor is connected with the oil pump which is respectively connected with a solenoid valve I and a overflow valve; the solenoid valve I is connected with the solenoid valve II which is respectively connected with an energy accumulator and a chuck; the chuck comprises an oil cavity I and an oil cavity II. The advantages of the following hydraulic chuck power source are as follows: the structure is novel; the power source has automatic compensation and shock-absorbing function in tension test, nearly does not consume energy, and has low noise. The following hydraulic chuck power source adopts operation of an electric button so as to complete clamping and loosing of the sample and reduce labor intensity and increase work efficiency. Meanwhile, the independent configuration leads the work to be more reliable and leads the maintenance to be more convenient.
Description
Technical field
The utility model belongs to materials mechanics experimental device field, is mainly used in universal hydraulic testing machine.
Background technology
At present, domestic hydraulic chuck power source adopts the constant pressure type oil sources more, and this type of control energy consumption is bigger, can't be in tension test to sample from the motion tracking clamping, do not have vibration-absorbing function yet, noise is bigger simultaneously.
Summary of the invention
The utility model provides a kind of trailing type hydraulic chuck power source, and the control energy consumption that exists when solve adopting the constant pressure type oil sources is bigger, can't be in tension test to sample from the motion tracking clamping, do not have vibration-absorbing function, simultaneously the bigger problem of noise yet.The technical scheme that the utility model is taked is: the oil suction filtrator is connected with fuel tank, this oil suction filtrator is connected with oil pump by pipeline, motor is connected with oil pump, this oil pump is connected with surplus valve with solenoid valve one respectively, this solenoid valve one also is connected with solenoid valve two, this solenoid valve two is connected with chuck with accumulator respectively, this chuck bag oil pocket one and oil pocket two.
The utility model advantage is novel structure, not only has automatic compensation and vibration-absorbing function in tension test, consumed energy hardly, and noise is very low.Adopt the operation of electric button, finish clamping, unclamp, reduce labor intensity, increase work efficiency sample.Because separate configurations makes work more reliable, keep in repair more convenient simultaneously.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Principle of work, when starting motor 2, motor 2 drives oil pump 3 to begin to provide fluid to oil circuit, owing to be in off working state, solenoid valve 5 metas, be that zero condition is the drain charge state, fluid directly flows back to fuel tank by solenoid valve 5, making system be in pressure is zero condition, consumed energy hardly.
When 602 whiles of the electromagnet on electromagnet on the solenoid valve 1 501 and the solenoid valve 26 were charged, oil pump 3 provided fluid and pressure for the oil pocket 802 of chuck 8 by solenoid valve 1, solenoid valve 26, has so just finished the action of unclamping of 8 pairs of samples of chuck; When 601 whiles of the electromagnet on electromagnet on the solenoid valve 1 501 and the solenoid valve 26 are charged, oil pump 3 solenoid valves 1, solenoid valve 26 provide fluid and pressure for the oil pocket 801 of chuck 8, so just finished the clamping action of 8 pairs of samples of chuck, also made accumulator 7 store fluid simultaneously with certain pressure.Oil pump provides the size of pressure to determine by regulating surplus valve 4.
In the drawing process of sample, because the distortion of chuck and the axial deformation of sample, the fixture block of chuck 8 produces axial slip, and communicate with the oil pocket 801 of chuck 8 owing to accumulator 7 this moment, accumulator 7 will be automatically to its additional fluid, finishes 8 pairs of samples of chuck from the motion tracking clamping.And accumulator 7 can also absorb when sample fracture because the impact energy that sample fracture produced.
Anchor clamps oil sources separate configurations, reliable operation, easy to maintenance.And use the operation of electric button, finish the clamping of sample, unclamp, reduce labor intensity, increase work efficiency.
