The specific embodiment
Below provide specific embodiment of the utility model, it should be noted that the utility model is not limited to following specific embodiment, all equivalents of doing on present techniques scheme basis all fall into protection domain of the present utility model.
Defer to technique scheme, as depicted in figs. 1 and 2, the present embodiment provides a kind of hydraulic regulation fixture for turning tool, comprise knife rest bare terminal end 15, in the upper end of knife rest bare terminal end 15, be provided with upper flat plate 2, on upper flat plate 2, be provided with for clamping the fastening bolt 14 of lathe tool, in the lower end of knife rest bare terminal end 15, be provided with base 1, between base 1 and upper flat plate 2, be provided with parallel with upper flat plate 2 and can be with respect to lower dull and stereotyped 3 of upper flat plate 2 motions;
Hydraulic pressure casing 4 is installed on base 1, hydraulic oil container 7, the first hydraulic jack 8 and the second hydraulic jack 9 are installed in described hydraulic pressure casing 4, hydraulic oil container 7 is connected with the first hydraulic jack 8 by the first check valve 16, and the conducting direction of the first check valve 16 is from hydraulic oil container 7 to first hydraulic jacks 8; The first hydraulic jack 8 is communicated with the second hydraulic jack 9 by the second check valve 17, and the conducting direction of the second check valve 17 is from the first hydraulic jack 8 to second hydraulic jacks 9; The second hydraulic jack 9 is connected with hydraulic oil container 7 by pressure release control valve 6, forms the closed loop oil circuit of an one-way flow; Pressure release control valve 6 is arranged on the closed loop oil circuit pressure release that is used to one-way flow on hydraulic pressure casing 4;
In hydraulic pressure casing 4, be fixedly installed hinged support frame 11, hinged support frame 11 is hinged with one end of regulating handle 5, the other end of regulating handle 5 stretches out hydraulic pressure casing 4, on regulating handle 5, being hinged with the first plunger 10, the first plungers 10 is arranged in the first hydraulic jack 8 for the closed loop oil circuit pressurization to one-way flow;
The second plunger 12, the second plungers 12 and lower dull and stereotyped 3 are installed in the second hydraulic jack 9 to be fixedly linked and to be used to lower dull and stereotyped 3 pressure is provided.
The volume of the second plunger 12 is greater than the volume of the first plunger 10, and the second plunger 12 is used to lower dull and stereotyped 3 pressure is provided.Its based on principle be pascal's principle, liquid pressure is everywhere consistent, in the system of balance, above smaller plunger, applied pressure is smaller like this, and on large plunger, applied pressure is larger, can keep the static of liquid like this.So by the transmission of liquid, can obtain the different pressure on different ends, control large pressure with regard to available little pressure like this.
Between all parts in the closed loop oil circuit of one-way flow, by petroleum pipeline 13, be communicated with, hydraulic oil enters successively all parts in the closed loop oil circuit of one-way flow from hydraulic oil container 7 by petroleum pipeline 13, finally in the situation that pressure release control valve 6 is opened, be back in hydraulic oil container 7.
The course of work of the present utility model is as follows:
Hydraulic regulation fixture for turning tool of the present utility model has utilized hydraulicdriven operation principle.Knife rest bare terminal end 15 is fixed on lathe saddle, and regulating fastening bolt 14 to make lathe tool handle of a knife upper end reach a height is the height that Lathe tool tip arrives workpiece axial line place, and manual adjustments regulating handle 5 drives the first plunger 10 to move up and down.When the first plunger 10 moves upward, it is large that the annular seal space volume of the first hydraulic jack 8 becomes, and pressure reduces, and forms parital vacuum, and the fluid in hydraulic oil container 7, under atmospheric pressure effect, backs down the first check valve 16, through petroleum pipeline 13, enters the first hydraulic jack 8; When the first plunger 10 moves downward, the annular seal space fluid pressurized of the first hydraulic jack 8, pressure raises, force the first check valve 16 to be closed, the second check valve 17 is opened and to the second hydraulic jack 9 chamber discharge pressures oil, promote to move on the second plunger 12, drive on lower flat board 3 and handle of a knife and move, when reaching a certain height, step up cutter.When regulating handle 5 stops moving, the annular seal space oil liquid pressure of the second hydraulic jack 9 forces the second check valve 17 to be closed, and this is flat board 3 and cutter stop motion at present.By the clamping pressure of micro-positioning regulators regulating handle 5 and pressure release control valve 6 adjustable lathe tools.If open fluid in pressure release control valve 6, the second oil cylinder 9 chambeies, through valve 6, flow back to hydraulic oil container 7, lower dull and stereotyped 3 and lathe tool under the effect of gravity, decline, lathe tool is removed.
