Embodiment
As shown in Figure 1, described one-way pneumatic hydraulic pressure anchor clamps are meant that its gas-liquid power-increasing cylinder is one.Described pressing jig includes fixed head, support bar 9, sliding panel 5, chuck and gas-liquid power-increasing cylinder 1; Described fixed head is divided into upper mounted plate 3 and bottom plate 7, is individually fixed in the two ends of support bar 9; Between the scope that two fixed heads are formed relatively, a sliding panel 5 is arranged, but its easy on and off motion on support bar 9; Be fixed with chuck 6 on the sliding panel 5; The cylinder body of described gas-liquid power-increasing cylinder 1 is fixed on the fixed head 3 on top, the aperture that the working piston bar 2 of gas-liquid power-increasing cylinder 1 passes through the formation of top tie plate 3 middle parts is connected with sliding panel 5 by a web member 4, described web member 4 is one " protruding " shape right cylinder, there is a hole towards working piston bar 2 direction openings the upper end of its " protruding " shape, the diameter in this hole is a bit larger tham the diameter of working piston bar 2 terminations, this hole forms a hole vertically, there is internal thread on the hole surface, there is external thread on the surface of working piston bar 2 terminations, and working piston bar 2 promptly is connected with web member 4 by screw thread; Web member 4 is fixedlyed connected with sliding panel 5; Be fixed with chuck 8 on the fixed head 7 of bottom, place the workpiece 10 that needs processing on it.In above-described fixedly connected mode, all adopt bolted mode.
In the use, when gas-liquid power-increasing cylinder 1 produced force-stroke, the working piston bar 2 of gas-liquid power-increasing cylinder 1 drove the chuck 8 directions motion of chuck 6 on lower tie plate 7 on sliding panel 5 and the sliding panel, until contacting with workpiece 10 and workpiece 10 being applied certain pressure.
Illustrate below by explaination how pneumatic quick the and bigger performance of hydraulic pressure output pressure of Pneumatic hydraulic pressing jig embodies to gas-liquid power-increasing cylinder 1 principle of work.
Be illustrated in figure 3 as the fundamental diagram of gas-liquid power-increasing cylinder, it be divided into five impulse strokes:
1. stationary state;
2. F.F. stroke: main control valve 17 is opened, and gas enters the right side air cavity of working piston bar air cavity 20, and working piston bar 2 rolls away under gas pressure, has produced extrernal resistance up to running into workpiece in a certain position, and extrernal resistance is opened the automatic pressure-increasing valve 18 of control stroke;
3. automatic pressure-increasing valve is opened: working piston bar 2 has run into workpiece and has produced external resistance, and automatic pressure-increasing valve 18 is opened automatically, and gas enters force-stroke air cavity 23, and reinforcement piston 22 force-stroke begin;
4. operational forces stroke: reinforcement piston 22 sealing working oil chambers 21, and extruding makes its oil pressure reach high value, and this oil pressure acts on working piston bar 2 back, finishes force-stroke, and workpiece is extruded moulding or is subjected to pressure greatly;
5. backstroke: behind the conversion main control valve 17, automatic pressure-increasing valve 18 air in the force-stroke air cavity 23 of draining automatically, working piston bar 2 and reinforcement piston 22 are got back to initial position.
The effect of throttling valve 19 is the switching time of regulating F.F. stroke and force-stroke.When working piston bar 2 ran into external resistance in arbitrary position of F.F. stroke, the automatic pressure-increasing valve 18 of gas-liquid power-increasing cylinder 1 was opened automatically, can automatically realize the conversion from the F.F. stroke to force-stroke.Throttling valve 19 is exactly to control opening the time of automatic pressure-increasing valve 18, and throttling valve 19 is turned down, and diminish switching time, and automatic pressure-increasing valve 18 opening speeds are fast; Throttling valve 19 is transferred big, becomes big switching time, and automatic pressure-increasing valve 18 opening speeds are slack-off.
Pneumatic be embodied in for second step fast, after main control valve 17 was opened, the gas piston rod 2 that pushes the work forward very soon touched workpiece; Present the 3rd step of the big pressure body of hydraulic pressure output and the 4th step, working piston bar 2 is stressed to move and seals working oil chamber 21 generation hydraulic oils to the workpiece direction, and the piston rod 2 that pushes the work forward acts on workpiece, makes workpiece deformation or stressed.
As shown in Figure 2, described two-way pneumatic hydraulic pressure anchor clamps are meant that mainly its gas-liquid power-increasing cylinder is two.Gas-liquid power-increasing cylinder 1 is connected with chuck 6 with sliding panel 5 by web member 4, and is relative, and two-way gas-liquid power-increasing cylinder 16 is connected with two-way sliding panel chuck 11 with two-way sliding panel 12 by two-way web member 13.During gas boosting, the working piston bar 2 of gas-liquid power-increasing cylinder 1 moves downward, drive sliding panel 5, chuck 6 to another chuck 11 directions motion, the working piston bar 14 of two-way gas-liquid power-increasing cylinder 16 moves upward, drive two-way sliding panel 12, chuck 11 to another chuck 6 directions motion, chuck 6 is with chuck 11 clamping work pieces 10 and produce certain pressure.
One-way pneumatic hydraulic pressure anchor clamps can be to the operation of can exerting pressure of relatively thick or relatively thin workpiece.Relatively thinner workpiece is exerted pressure, when the working piston bar can't the Contact Thin part because delivery stroke is not enough, the general fixing fixed head of adjustment and gas-liquid power-increasing cylinder and the position of support bar of adopting, make that distance is dwindled between fixed head and the thin part, the distance of thin like this part and working piston rod end head just within its delivery stroke scope, can realize the operation of exerting pressure.
But the operating process of at every turn adjusting fixed head is cumbersome, so also can address the above problem by the gas-liquid power-increasing cylinder that adopts big delivery stroke.The maximum delivery stroke of gas-liquid power-increasing cylinder working piston bar is 200mm in the market, but price is too expensive, considers cost performance, generally adopts the gas-liquid power-increasing cylinder of 100mm delivery stroke in the majority.Under the delivery stroke permanence condition, with respect to one-way pneumatic hydraulic pressure anchor clamps, two-way pneumatic hydraulic pressure anchor clamps are because adopted two gas-liquid power-increasing cylinders to act on workpiece simultaneously, distance at two fixed heads, the size of two chucks waits other conditions constant, to its total delivery stroke of Pneumatic hydraulic pressing jig is single gas-liquid power-increasing cylinder delivery stroke sum, be equivalent to increase by one times, like this, two-way pneumatic hydraulic pressure anchor clamps can be adjusted fixed head and come exerting pressure to the different-thickness workpiece, manpower and time have been saved, simultaneously, because also adopted the gas-liquid power-increasing cylinder of 100mm delivery stroke, promptly be exactly the price sum of two gas-liquid power-increasing cylinders, also competitively priced many than the gas-liquid power-increasing cylinder of 200mm delivery stroke.
