Abstract
According to the problems of current cylinder force-measuring devices, which are too big, and need to be driven, the utility model discloses a simple, portable hydraulic-ram force-measuring device based on pressure and area formula. It is composed of a cylinder (2), a cylinder cover and a display (3). The cylinder cover (1) under the exogenic action is sealed and installed on the cylinder (2), which can make linear motion along with inner wall of the cylinder (2). The display (3) oil-in is communicated with pressure chamber of cylinder through oil pipe or directly. It has the advantages of simpleness and portability.
Description
Technical field
The utility model relates to a kind of device for measuring force, especially utilizes hydraulic jack to realize the device of dynamometry purpose, specifically one we based on the hydraulic oil cylinder type device for measuring force of pressure and power and area formula.
Background technology
At present, different according to method of measuring and principle, various device is arranged, the method of ergometry commonly used is to adopt oil cylinder to change on the engineering, promptly equal pressure divided by area according to pressure, under the constant prerequisite of area, the pressure in the oil cylinder is just in direct ratio with pressure, conversion through suitable just can allow indicator gauge directly demonstrate the size of effect.Existing this type of device for measuring force provides power by motor or manpower by oil cylinder, drives oil cylinder pressure is delivered to tensimeter, and volume is big on the one hand for this structure, and Heavy Weight carries inconvenience, and range is less on the other hand, and conversion is not directly perceived, and range of application is less.
Summary of the invention
The purpose of this utility model is that the volume that exists at existing oil cylinder device for measuring force is bigger, needs the problem of motor or manual drives, designs a kind of hydraulic oil cylinder type device for measuring force based on pressure and area formula simple in structure, easy to carry.
The technical solution of the utility model is:
A kind of hydraulic oil cylinder type device for measuring force based on pressure and area formula, it is characterized in that it mainly is made up of oil cylinder 2, oil cylinder cover 1 and display 3, be subjected to oil cylinder cover 1 sealing of external force effect to be installed on the oil cylinder 2 and can move as straight line, display 3 oil-ins or by oil pipe or directly communicate with the pressure chamber of oil cylinder 2 along the inwall of oil cylinder 2.
Guide pole 4 is installed in the oil cylinder 2, and described oil cylinder cover 1 is sleeved on the described guide pole 4.
Above-mentioned guide pole 4 can be hollow structure.
The utlity model has following advantage:
1, simple in structure, intuitive display.As long as equal the formula of pressure, by suitable calculating, former tensimeter is represented that the numerical value of pressure is converted into the power value and gets final product, and change straightforward procedure divided by area according to pressure.
2, simple in structure, need not power drive, easily manufactured, cost is lower.
3, volume is little, is easy to carry.
4, purposes is wide, through suitable transformation, can manufacture various device for measuring force, weighing device according to the difference of the mode that acts on the power on the oil cylinder cover.
5, oil cylinder cover directly is sleeved on the guide pole, has saved oil inlet pipe, has improved reliability.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Following structure drawings and Examples are further described the utility model.
As shown in Figure 1.
A kind of hydraulic oil cylinder type device for measuring force based on pressure and area formula, it is mainly by oil cylinder 2, oil cylinder cover 1 and display 3 are formed, the guide pole 4 of hollow structure is installed in the oil cylinder 2, oil cylinder cover 1 spinning is on described guide pole 4, be subjected to oil cylinder cover 1 sealing of external force effect to be installed on the oil cylinder 2 and can move as straight line along the inwall of oil cylinder 2, display 3 can adopt mechanical type commonly used or electronic pressure table to convert, only need get final product manometric oil-in or by oil pipe or directly communicate with the pressure chamber of oil cylinder 2 through after calculating the value of expression pressure on the former tensimeter being modified to the power value.Between the casing wall of the outer wall of oil cylinder cover 1 and oil cylinder 2 and on the bar wall of the center pit of oil cylinder cover 1 and guide pole 4 corresponding sealing ring all should be installed.
On oil cylinder cover 1, be subjected to external force F and do the time spent, behind the hydraulic oil pressurized in the oil cylinder 2, pressure increases, the value P=F/S of pressure, and wherein S is the floorage of oil cylinder cover, when S is constant, external force F and pressure P relation in direct ratio, promptly external force F is big more, and then pressure P equal proportion increases, therefore the pressure values that shows in the indicator gauge 3 just can convert the suffered external force F value of oil cylinder cover to, thereby makes that demonstration is very directly perceived.
Claims (3)
1, a kind of hydraulic oil cylinder type device for measuring force based on pressure and area formula, it is characterized in that it mainly is made up of oil cylinder (2), oil cylinder cover (1) and display (3), be subjected to oil cylinder cover (1) sealing of external force effect to be installed in oil cylinder (2) and go up and can move as straight line, display (3) oil-in or by oil pipe or directly communicate with the pressure chamber of oil cylinder (2) along the inwall of oil cylinder (2).
2, the hydraulic oil cylinder type device for measuring force based on pressure and area formula according to claim 1 is characterized in that guide pole (4) is installed in the oil cylinder (2), and described oil cylinder cover (1) is sleeved on the described guide pole (4).
3, the hydraulic oil cylinder type device for measuring force based on pressure and area formula according to claim 2 is characterized in that described guide pole (4) is a hollow structure.
