Abstract
The utility model relates to an instrument which causes the static force exerted on the stressed body to automatically change the size and to make measurement. The utility model is of a completely sealed container which is filled with hydraulic oil, and is mainly composed of a cylinder and two plungers which have different area and are respectively connected with the stressing body and the stressed body. Two plungers are correspondingly provided with two plunger cavities filled with the hydraulic oil, and the plunger cavities are of central cavities of the cylinder. Two plunger cavities are mutually communicated and are provided with sealing elements for sealing the cylinder and the plunger cavities. The utility model is used for various force applying apparatus and instruments, such as manipulators, pulling machines, press machines, etc. The force applying range is enlarged, and the power consumption is decreased.
Description
The utility model is that a kind of static(al) that is applied on the beaer that makes changes its big or small device automatically, the equipment that be specially adapted to variously to draw, press, grab, clamping force need increase and decrease and to force measurement.
The hydraulic actuators that adopt in the time of generally need obtaining enough big power now more, as lifting jack, supercharger etc., its Hydraulic Elements all must and hydraulic pump etc. connect and compose the loop, so structure is comparatively complicated, volume greatly, use inconvenience.
It is a kind of simple in structure, easy to use and need not the automatic force-boosting and the measuring appliance of mechanisms such as hydraulic pump that the purpose of this utility model is to provide.
The technical scheme that the utility model is taked is: it is one and is full of hydraulic oil, Mi Feng container fully, input end and output terminal that two pistons promptly form power are set in the container, its corresponding have two plunger shaft (cylinder body center cavity) that are full of hydraulic oil, two plunger shaft are interconnected, the limited block of two-piston with respect to the container location is set, input, the piston area of the output terminal size that can change power that causes not of uniform size, be that output terminal obtains the piston area greater than input end, obtain power at output terminal greater than input end, form booster, also can make the piston area of the piston area of output terminal, obtain power less than input end at output terminal less than input end.
Plunger shaft is communicated with a dynamometry device, as the dynamometry table, constitutes measuring appliance, can measure output terminal power.

Structure as shown in Figure 1, the utility model is by cylinder body 4 and piston 3,8 center cavities that fit in a complete closed are full of the container of hydraulic oil, the diameter in hole, two gardens (center cavity) and the diameter of two-piston are complementary on the cylinder body 4, with O- ring seal 2,7,10 sealings, the boss at cylinder body 4 centers and two nuts 1,9 all for designing piston spacing (outwards not extracting out), the aperture that exhaust was used when the booster oiling was set is also sealed with plug 6 and O-ring seal 5, piston 3,8 link to each other with beaer with force body respectively, the input end of formation power and output terminal, the size of cylinder body and piston area depend on the size of requirement input power and the size of reinforcement coefficient.The output terminal piston area constitutes booster greater than the input end piston area in the present embodiment, is applicable to the reinforcement of pressure, folder, grip.
Structure as shown in Figure 2, among this embodiment equally by cylinder body 4 and piston 3,8 center cavities that constitute complete closed are full of the container of hydraulic oil, setting is in order to piston 3,8 spacing central boss and nuts 1,9, wherein piston 8 is for having the structure of center pit, and sealed with O-ring seal, the piston rod of valve piston 3 passes the center pit of big piston 8, the power output end of the piston force side of valve piston and big piston (i.e. two piston rods) is all at the same end of cylinder body thus, plug 6 is that the vent port when filling oil designs, the piston area of output terminal is applicable to the booster to the pulling force reinforcement greater than the piston area of input end in the present embodiment.In the present embodiment, 2,5,7,10 are O-ring seal, are used for the sealing of cylinder body and oil pocket.
Structure is on the basis of embodiment 2 load-sensing unit to be set as shown in Figure 3, promptly constitutes force measurement device, go up connection one dynamometry gauge outfit 12 in plunger shaft (oil pocket), and with sealing gasket 11 junction is sealed, can constitute dynamometer, this embodiment generally is used for the measurement by magnification to pulling force.
Structure shown in accompanying drawing 4,5,6 is used the utility model auto-booster and force measurement device, only needs the output piston bar of booster is linked to each other with stressed member, and the input piston bar links to each other with force body; Can reinforcement and measure; Accompanying drawing 4 is for applying the synoptic diagram of pressure, clamping force through booster, booster adopts the structure of embodiment 1, accompanying drawing 5 is for applying the synoptic diagram of pulling force through booster, booster adopts the structure of embodiment 2, force body can be hand or mechanical equipment configuration, with the reinforcement coefficient is that the booster of K (big piston and valve piston area than) is installed in the output that the output of drawing, make on the pressure, apparatus for fastening booster becomes equipment, and its power can increase K doubly.
Accompanying drawing 6 is the bench vice synoptic diagram of band booster, for the power that makes clamping work pieces enough big, the vice that is installed on the worktable can be located workpiece through big screw rod, the vice small screw is connected with the input end piston rod of booster, output terminal big piston bar connects application of force jaw, and turn vice small screw clamps workpiece, and this vice can be used on the precision stage, need not apply big external force, but can be light obtain enough big clamping force.
As need power output is measured, on plunger shaft, be communicated with load-sensing unit, promptly constitute measuring appliance as the dynamometry gauge outfit.
