The specific embodiment
Among Fig. 1, " recessed " shape supporting seat 1 is provided with the little square block of band through hole.The two sides of little square block are milled with the opposite gradient of direction, and the centre is a clear opening.The through hole that drive link 2 passes on the live splint 5 is loaded in the through hole of little square block.Locking folder 3 is equipped with at the screw rod position of drive link 2 front ends, and locking folder 3 is provided with the screwed hole that cooperates with drive link 2 screw rod positions.Be useful on the thick cylinder of drive link 2 rear ends and promote the step surface of live splint 5 to the translation of workpiece periphery reinforcement direction.Packing ring 6 is between the step surface of thick cylinder on live splint 5 and the drive link 2.Packing ring 6 is cylinders that an end mill has constant slope, and the axle center has through hole.Live splint 5 is a square block, and the centre is the through hole that constant slope is arranged.Locking folder 3 is identical with live splint 5 profiles, and the centre is the screwed hole that constant slope is arranged, and the gradient direction is opposite with the gradient direction of live splint 5.Live splint 5, locking folder 3 assembling back profiles such as the same clip that opens mouth.Place, the two ends face of through hole is the inclined-plane on the supporting seat 1 medium and small square block, and the angle that two inclined-planes form is identical with the angle that live splint 5, locking folder 3 form.Bearing pin 4 is assemblied on the supporting seat 1.Handle 7 is contained on the thick cylinder of drive link 2.
Among Fig. 2, supporting seat 1 is fixed on the anchor clamps base plate 8 by screw.Bearing pin 4 is housed on the supporting seat 1.After assembling with drive link 2, live splint 5, locking folder 3 lay respectively at the left and right sides of little square block on the supporting seat 1, i.e. the both sides of workpiece periphery reinforcement 9.Packing ring 6 is between the thick cylinder and live splint 5 of drive link 2.Handle 7 is housed on the drive link 2.
Among Fig. 3, Fig. 4, supporting seat 1 is a large square spare, and two screwed holes are arranged at the bottom, can fix by screw and anchor clamps base plate.There is the little square block (forming a projection) that has through hole at supporting seat 1 crown center position, and its both sides have the opposite gradient of direction, and total angle is a °, and gradient a ° identical with large thin-wall workpiece periphery reinforcement gradient.Supporting seat 1 one sides are to prevent the spill position of interfering with workpiece periphery reinforcement.The distance of through hole just makes live splint, locking can lie in a horizontal plane on the P face after clamping and joining on P face and the little square block; The P face is provided with the hole of assembling pivot pin 4.The concrete shape of supporting seat 1 can be square block by the concrete profile decision of workpiece, and the clamping position also can be inverted "L" shaped with economical with materials, weight reduction when higher.
Among Fig. 5, drive link is a stepped ramp type elongated cylinder; The drive link rear end is thick cylinder 10, and the drive link front end is screw rod position 13, is the polished rod position 12 identical with screw rod position 13 diameters in the middle of the drive link.Have the hole of dress handle on the thick cylinder 10.Drive link is in the process that screws with locking folder, and the step surface 11 on its thick cylinder 10 constantly promotes the direction translation to workpiece periphery reinforcement of packing rings, live splint.
Among Fig. 6, live splint 5 is a square block, and the centre is that gradient is the through hole of (a/2) °, and the polished rod position of itself and drive link is little matched in clearance.After packing ring, live splint 5 are enclosed within drive link polished rod position, the two sides of packing ring respectively step surface, develop with the contact-making surface of live splint 5.
Among Fig. 7, locking folder 3 is identical with the live splint profile, is the screwed hole of (a/2) ° but the centre is a gradient, and its gradient direction is just opposite with the gradient direction of live splint, and its screwed hole matches with the screw rod position of drive link.
On the supporting seat 1 on the gradient a of little square block °, live splint 5 on the gradient (a/2) of through hole °, the locking folder 3 gradient (a/2) of through hole ° relevant with the gradient of workpiece periphery reinforcement 9, what select for use here is the identical states of the peripheral reinforcement 9 two sides gradients of workpiece.If workpiece periphery reinforcement 9 is not provided with gradient, then on the supporting seat 1 on gradient a ° of little square block, live splint 5 on the gradient (a/2) of through hole °, the locking folder 3 gradient (a/2) of through hole be zero, the displaying of above-mentioned two kinds of the utility model clamp mechanism is arranged among Fig. 2.
Concrete operations of the present utility model, clamping step are:
After successively being enclosed within on the drive link 2, packing ring 6, live splint 5 pass the through hole of little square block on the supporting seat 1;
Stir handle 7, make progressively precession drive link 2 screw rod positions 13 of locking folder 3, and along direction B progressively to 9 translations of workpiece periphery reinforcement; The promotion lower edge direction A of live splint 5, packing ring 6 step surface of thick cylinder 10 on drive link 2 that is positioned at workpiece periphery reinforcement 9 opposite sides simultaneously is constantly to 9 translations of workpiece periphery reinforcement;
Live splint 5, locking folder 3 are that fulcrum develops and clamping work pieces periphery reinforcement 9 two sides with bearing pin 4 finally progressively near workpiece periphery reinforcement 9.
The utility model effectively utilizes the principle that screws of screwed hole and threaded rod, by the step surface on the drive link 2 11, live splint 5 and locking folder 3 are arranged in the two sides of workpiece periphery reinforcement 9, constantly screwing by drive link 2 and locking folder 3 subsequently, make live splint 5 progressively press close to workpiece periphery reinforcement 9 from two opposite directions of A, B, until clamping work pieces periphery reinforcement 9 with locking folder 3.The utility model has been broken through the frame mode of traditional unidirectional, press-down type clamping work pieces, adopt structural approach two-way, peripheral clamping work pieces, not only reduced the distortion that the large thin-wall workpiece produces to greatest extent in clamping and milling process, guaranteed the crudy of workpiece, and simple and compact for structure, to make precision low, easy to operate, for the large thin-wall workpiece provides a kind of brand-new, practicability and effectiveness, had the clamping means of extensive generalization.
