As shown in Figure 1, 2, Integrated Power Unit 60 of the present utility model comprises air pressure portion 61, middle seat 62, oil pressure portion 63 and base 64 4 partly; The pneumatics dish 612 of plunger 611 upper ends of establishing in air pressure portion 61 mats will be gone up, the bottom is divided into 614 liang of spaces of air-pressure chamber 613 and air-capacitor chamber, the hydraulic chamber 620 of seat 62 is then gone into to be arranged in plunger 611 lower ends, and cylinder portion 61 tops are provided with the T type non-return valve 615 that can control one-way flow, because of pneumatics dish 612 lifting surface areas big, and plunger 611 front ends are little in order to the contact-making surface that forces in hydraulic chamber 620, so can effectively improve the hydraulic piston 633 descending pressure-speeds of forging a knife of below by this, and the middle seat 62 of 614 belows, air-capacitor chamber is provided with gas bleeder valve 622, the exhaust of air-capacitor chamber 614 when descending for pneumatics dish 612, and when the 612 up recoveries of pneumatics dish, the gas of air-pressure chamber 613 is then discharged by T type non-return valve 615, and the action of air pressure portion 61 is used for manual tool changing.

Be positioned at 63 in air pressure portion 61 and oil cylinder portion for middle 62, central authorities are hydraulic chamber 620, move in row wherein for plunger 611, middle seat 62 is the outer oil sump 631 of control oil pressure portion 63 and the control module of inner oil sump 632, and it has into oil, removes the residual function of removing gas and simplifying the operation, which is provided with an oil filler point 621, fresh oil can be injected outer oil sump 631, and be provided with a floating drum 629 and stretch into outer oil sump 631, with the storage of control outer oil sump 631, when being lower than certain value, promptly can send signal through circumscripted power line 6291; And between the path of inside and outside oil groove 632,631, promptly be positioned at the fuel sucking pipe 628 that outer oil sump 631 is provided with filter screen by one, through the first oilhole 627A, enter inner oil sump 632 by the second oilhole 627B, and first and second oilhole 627A, 627B enter the path of inner oil sump 632 through magnetic valve 627 controls of a peripheral hardware, when the bubble in the desire eliminating inner oil sump 632, ability and outer oil sump 631 form paths.For exhaust, be provided with a blowhole 626 in middle seat 62, it communicates with outer oil sump 631, an and porus excretorius 624 that communicates with inner oil sump 632, porus excretorius 624 is subjected to one to adjust screw 623 its paths of control, when in the inner oil sump 632 bubble being arranged, then on the newel 641, following journey will have error to produce, and after being learnt by sensor 65 signal takes place promptly, but the staff just mat blowhole 626 pressure-air is sent into, also make magnetic valve 627 open path simultaneously, force the oil of outer oil sump 631 to follow first from fuel sucking pipe 628, the second oilhole 627A, 627B enters inner oil sump 632 fast, and gas is discharged by porus excretorius 624, afterwards, lock screw 623 gets final product again, if in the time of fresh oil will being injected inner oil sump 632, also follow same action, can fulfil assignment fast, simple to operation, be one of the utility model feature.

The inner oil sump 632 of oil pressure portion 63 and hydraulic chamber's 620 coordinatioies of middle seat 62 have a hydraulic piston 633 at inner oil sump 632, can control the newel 641 descending actions of forging a knife of base 64, and mat outer oil sump 631 can be isolated the friction noise of hydraulic piston 633.

Base 64 is provided with newel 641, the upper end is a plunger 6411, and plunger 6411 is provided with protrusion head 6412, make forging a knife during mechanism 30 of the comprehensive machine that is applied to need the strong impaction work done, please cooperate shown in Figure 3, but mat protrudes head 6412 inserts disc spring 645 location, and can reduce the noise of hydraulic piston descending impact of 633 moment, and plunger 6411 belows are provided with spring 646, can cooperate the 50 descending oil pumping of the oily mechanism of sending of automatic tool changer 40 to move, and help newel 641 to reset, with the bump distance X of maintenance with main shaft 32.Wherein, newel 641 and spring 646 are located in the position, hole 647 of base 64, newel 641 protrudes from base 64 places in addition and is equipped with impact block 642, forge a knife to go the application of force, form a groove 6414 at plunger 6411 sides, and on its position, base of passing through 64 hole 647 walls, be provided with and keep bolt 644 and go into to be arranged in groove 6414, so that newel 641 certain directly to motion, and unlikely turn.

Be applied to the forging a knife during mechanism 30 of comprehensive machine, when avoiding working head 31 work, infiltrate cutting oil and processing detritus, causing influences the accuracy that main shaft 32 is held cutter, one blowhole 643 can be set on base 64, and newel 641 is provided with downward through hole 6413 and venthole 6421 with impact block 642, make when impact block 642 moments bump main shaft 32 unloads cutter, promptly can be by blowhole 643 input gases at high pressure, via through holes 6413, venthole 6421 are blown into the centre bore of main shaft 32 rapidly, and can in the lump oil stain, detritus be removed.

Compared with prior art, the utlity model has following effect:

In sum, the Integrated Power Unit of the utility model oil pressure and air pressure, not only in conjunction with oil pressure air pressure in one, reach be swift in motion and save time, laborsaving and effect that noise is little, the function that can cut true increase power set, practical.

More than narration is to borrow preferred embodiment that architectural feature of the present utility model is described, is not to be used to limit protection domain of the present utility model.
