The front end 211' and the push rod through hole 323 provide the push rod 34 through and into the oil storage hole 335 of the piston 33; and the rear end of the piston 33 is placed in the spring receiving hole κι, and the elastic member 35 is disposed in the spring receiving hole 321 such that the end of the elastic member 35 abuts against the bottom end of the spring receiving hole 321 and the other end abuts against the rear end of the piston 33. The elastic member 35 is a dish spring or other kind of spring. The rear end of the piston 33 can be coupled with an oil seal fixing ring 36. The oil seal fixing ring 36 is provided with a push rod through hole 361 at the center to provide the push rod 34 through the oil seal fixing ring 36, and the elastic element g 5 sets. Closed on the periphery of the oil seal retaining ring 36. As shown in the fifth figure, when the double-clamp hydraulic vise of the present invention is used, the workpiece 50 can be placed between the first movable 颚μ and the fixed μ of the vise body 1, and another workpiece of the same size can be placed. 60 is placed between the second activity 颚 15 and the fixed cymbal 16 . In this manner, the user first pushes the switching sleeve 45 of the drive unit 4 back, and the insert block 451 is engaged with the fitting groove 461 of the torsion sleeve 46, and then the torsion sleeve 46 is rotated. When the torsion sleeve 46 rotates, the connecting sleeve 44 and the clutch sleeve 42 are rotated by the switching sleeve 45, and then the first screw 21 is driven to rotate through the clutch sleeve #42, and the first screw 21 can be rotated. The screw connecting ring 32, the hydraulic cylinder 31 and the piston 33 that drive the hydraulic unit 3 rotate, thereby simultaneously rotating the second screw 22, due to the first threaded portion 213 of the first screw 21 and the second thread of the second screw 22 The part 223 is in different spiral directions (one is a left helix and the other is a right helix), so when the synchronous rotation is performed, the first movable element u and the second movable 颚ls can be simultaneously approached to the workpiece 5〇, 6〇, until the first- Live (4) 14 and the second activity 颚 15 minutes call to turn 5 (), 6 ' ' can use the helical component to produce a lower mechanical clamping force, and the reaction force of the workpiece 50, 60 will make the first screw 21 When the second screw 22 reaches the level of _ 11 201206644, it can no longer be rotated. As shown in the sixth figure, in order to hold the workpiece 50, 00 more firmly at this time, the user can push the switching sleeve 45 forward to disengage the insert 451 from the recess 461 of the torsion sleeve 46, and then again The torsion sleeve 46 is rotated, because the torsion sleeve 46 at this time will no longer drive the switching sleeve 45, but only the sub-screw 43 is rotated and gradually moved forward, so that the ball 436 of the clutch section 433 is disengaged from the engagement. When the push rod 34 is driven and the rotating sleeve 46 is moved forward, the squeeze hydraulic oil 337 flows through the flow hole 336 to the oil chamber 313 as the front end 341 of the push cup 34 protrudes into the oil storage hole 335 of the piston 33. At this time, using the Pascal principle (Pascal, principle), as shown in the seventh figure, the hydraulic oil 337 can push the hydraulic cylinder 31, the screw connecting ring 32 and the first screw in the oil chamber 313 to move forward while also pushing the piston. 33 and the second screw 22 are moved backwards. Thus, the clamping force of the first movable jaw 14 and the second movable jaw 15 for the workpieces 50, 6〇 can be increased by the amount of oil pressure to achieve the effect of synchronous and stable clamping. On the contrary, when the torsion sleeve 46 is reversed, the screw 43 is rotated and gradually retracted. At this time, the elastic member 35 of the hydraulic unit 3 returns the thrust piston 33 to the original position, and the force of the oil pressure clamping can be released. Finally, the first activity 颚 14 and the second activity 颚 15 can be released from the workpieces 50, 60. In addition, since the clutch sleeve 42 of the driving unit 4 of the present invention can be progressively implemented as an axially movable structure, when the workpieces 50, 60 are determined to have different sizes, the difference is usually in the clutch sleeve. During the movement of 42, the double-seat hydraulic vise can still be used for clamping. As shown in the eighth figure, a large workpiece 5 〇 can be placed between the first movable piece 14 and the fixed cymbal 16, and then the smaller workpiece 6 〇 is placed in the second movable piece and the fixed cymbal 16 between. Then, the switching sleeve 45 is also pushed back to engage the insert block 451 with the fitting groove 461 of the barrel 12 201206644, and then the torsion sleeve 46 is rotated. When the twisting is too rotated, the connecting sleeve 44 and the clutch sleeve 42 will be rotated by the switching sleeve 45, and the first screw η, the screw connecting ring 32, the hydraulic cylinder 31, the piston 33 and the second can be driven through the clutch sleeve 42 at the same time. The screw step rotates 'the first activity 颚 14 and the second activity 颚 15 simultaneously approach the workpiece 5 〇, 6 〇, 'until the first movable element 14 contacts the workpiece 5 〇, when the second activity 颚 15 - Still not = touched 60. However, as shown in the ninth figure, the switching sleeve can be pushed further to disengage the insert 451 from the recess 461 of the torsion sleeve 46, and then re-twist, twist the sleeve 46, and twist at this time. The sleeve 46 will no longer drive the cutting cylinder 45' to drive only the sub-screw and gradually move forward, so that the ball 436 of the clutch section 433 is disengaged from the engaging hole 423 to simultaneously push the push rod % and drive the torsion sleeve 46. Moving forward, however, because the pressure of the hydraulic oil 3; 37 is large, the reaction force will cause the entire oil unit 3, the twin-screw unit 2 and the clutch, and the sleeve 42 to move backward while making the first activity 颚 1 * And the second movable piece 1 $ = is close to the workpiece 50', 60 until the error gap is eliminated, so that the hydraulic oil 337 can push the hydraulic cylinder 31, the screw connecting ring 32 and the first screw rod in the oil chamber 313 21 moves forward, and also pushes the piston 33 and the second screw 22 to move backwards, so that the clamping force of the first movable jaw 14 and the second movable jaw 15 for the workpieces 50, 60 can be increased by the amount of oil pressure to achieve synchronization. The effect of firm clamping. In summary, the double-clamp hydraulic vise of the invention can achieve the functions of stably clamping the workpiece, increasing the productivity, and simultaneously clamping two different size workpieces, and has practicality and creativity. The use of technical means is also novel and undoubted, and the efficacy and design purpose are in line with the fact that it has been reasonably improved. To this end, the invention patent application was filed according to law, but the fishing bureau was invited to give a detailed examination and the patent was granted as a prayer. 13 201206644 [Simple description of the diagram] The first figure is a combined perspective view of the hydraulic clamp of the double clamp seat of the present invention.
