Description

High thrust measuring device
Technical field
The utility model belongs to force measuring device field, and in particular to 1-3MN is big in high power hydraulic loading test platform Thrust-measuring device.
Background technique
In some high power hydraulic loading test platforms, thrust is especially big, up to 1-3MN, at this moment surveys to thrust Amount just becomes difficult.Tradition generallys use the sensor of wide range to high thrust measurement, however the sensor cost of wide range is high Expensive, single price is up to hundreds of thousands, and due to being difficult to demarcate, measurement accuracy is very low, it is difficult to meet job requirement.
Summary of the invention
The purpose of this utility model is to provide a kind of high thrust measuring devices, solve the high thrust measurement cost of 1-3MN Height, the low technical problem of measurement accuracy.
To achieve the above object, the utility model adopts the following technical scheme that realization:
High thrust measuring device, comprising: cylinder body, pressure regulation bar, pressure regulating screw, piston, end cap, load lid, film, lever, Force snesor;Wherein, it is machined with regulator hole in the side of the cylinder body, is machined with piston hole in the bottom of cylinder body;The pressure regulation Bar and pressure regulating screw are sequentially arranged on regulator hole from inside to outside, make to form precompressed in cylinder body by adjusting pressure regulating screw;It is described Piston is mounted on piston hole, has gap between the confined planes on the piston shaft shoulder and cylinder base piston hole;The end cap is by film It is pressed on cylinder body;The load lid passes through end cap and covers on film, has gap in the axial direction between load lid side and end cap;Institute It states lever to be mounted on cylinder body by pin shaft, lever one end is contacted with piston boss, the other end and force snesor Measuring head is in contact;The force snesor is fixed on cylinder body.
As the preferred of the utility model, steel ball is equipped between the pressure regulating screw and pressure regulation bar, pressure regulating screw passes through Steel ball pushes pressure regulation bar to be slowly inserted into regulator hole;When the pressure regulation bar is inserted into, O-ring seal, the O are equipped on pressure regulation bar Type sealing ring plays sealing function, prevents hydraulic fluid leak.
As the further preferred of the utility model, the piston is mounted on piston hole by O-ring seal;It is described thin Film equally passes through O-ring seal and is pressed on cylinder body, using the sealing function of sealing ring, prevents from leaking.
Still more preferably as the utility model, it covers in the load equipped with pit, it will be hydraulic when for loading In cylinder piston rod front end is placed on;The force snesor is positioned by clamping cap and is clamped on cylinder body.
The utility model measuring device use process is as follows:
After whole device has been assembled, pressure regulation bar and pressure regulating screw are taken out, hydraulic oil is injected by regulator hole, is inserted into pressure regulation Bar rotates pressure regulating screw, pushes pressure regulation bar slowly to enter by steel ball interior, forms 0.1 ~ 0.2Mpa of precompressed;Then by whole device It is mounted on rack, the load of hydraulic cylinder piston rod front end is in the pit that load covers when load;Due to load lid side and end Lid has a gap in the axial direction, thus load lid it is loaded after press to film, deformed after film stress, thus by load transfer to liquid In pressure oil, oil pressure is caused to increase;After oil pressure increases, thrust suffered by the piston of cylinder base is increased, and loads pushing away in lever left end Power also increases, and the ratio between size and film pressure size of this thrust are equal to piston hole area and cylinder diameter cross-sectional area The ratio between, it is 1:30;Under the action of lever central pin shaft, thrust is transmitted to right end in the ratio of 1:1, and loads in force snesor Measurement end, thus convert the load of 300t to the thrust of 10t size, that is, general force snesor can be used to be surveyed Amount.
The advantages of the utility model and good effect: compared with prior art, the measuring device structure letter of the utility model It is single, it is at low cost, can the high thrust to 1-3MN effectively measured, change the range of sensor, the measurement may be implemented and fill The expansion and diminution of measurement range are set, it is simple and practical, while the calibration of measurement accuracy may be implemented, improve measurement accuracy.
Detailed description of the invention
Fig. 1 is the utility model high thrust measuring device overall diagram.
Fig. 2 is the utility model high thrust measuring device sectional view.
Specific embodiment
To make those skilled in the art know more about the technical solution of the utility model and its advantage, below in conjunction with attached drawing to this Utility model is made with further elucidated above, but does not limit the protection scope of the present invention.
Refering to fig. 1, Fig. 2, high thrust measuring device provided by the utility model, comprising: cylinder body 5, pressure regulation bar 3, pressure regulation spiral shell Follow closely 4, piston 7, end cap 2, load lid 1, film 6, lever 8, clamping cap 9, force snesor 10;Wherein, in the side of the cylinder body 5 It is machined with regulator hole (unmarked), is machined with piston hole in the bottom of cylinder body 5;
The pressure regulation bar 3 and pressure regulating screw 4 are sequentially arranged on regulator hole from inside to outside, in the pressure regulating screw 4 and tune Steel ball 11 is equipped between compression bar 3, pressure regulating screw 4 pushes pressure regulation bar 3 to be slowly inserted into regulator hole, makes shape in cylinder body by steel ball 11 At precompressed (0.1 ~ 0.2Mpa), if hydraulic oil leaks after a period of use, precompressed is reduced, and can rotate pressure regulation spiral shell Nail, makes pressure regulation bar be inserted into deeper, re-forms precompressed;When the pressure regulation bar 3 is inserted into, O-shaped sealing is equipped on pressure regulation bar 3 Circle, the O-ring seal play sealing function, prevent hydraulic fluid leak;
