Description

Automatic centering rapid clamping fixture
Technical field
The present invention relates to a kind of rapid clamping fixture automatically, especially a kind of automatic centering eccentric rapid clamping press plate of adjustable thrust.
Background technology
Add man-hour in metal cutting, behind workpiece location, fixed to clamp with pressing plate, then use workpiece processing tool.Conventional fixation clip is to come in addition fasteningly with bolt, and service efficiency is not high, and after repeatedly using, the hex nut place in bolt can produce distortion, and last rounded state causes spanner to skid and cannot be wrenched; And the screw thread of screw thread and hex nut repeatedly under interlock, can cause thread abrasion and rotten tooth, causes and cannot lock, and service life is short.Chinese utility model patent number: 201120103422.3, a kind of eccentric rapid clamping press plate is disclosed, one end of pressing plate has indent feed groove, on pressing plate, be equipped with connecting rod, the lower end of connecting rod is connected with T-shaped nut, its upper end is connected with the woodruff key of a bias, and the lower end of woodruff key is connected with pressing plate contact, and handle has been threaded on woodruff key.Although this pressing plate can be realized Quick holding part, solve the defect that conventional fixation clip exists, but this pressing plate is to carry out compacting processing workpiece by the bias of woodruff key, compress necessary self-locking between later half round key and pressing plate, the clamping force of pressing plate clamping work pieces and clamping displacement can only regulate by adjusting connecting rod, extremely inconvenient, and, in the time that clamping force is excessive, after woodruff key loosens, pressing plate cannot unclamp.In addition, cannot be applicable to need the workpiece processing that centering clamps and the workpiece with strain after compression, the timely fine setting of thrust.Therefore, need a kind of energy automatic centering clamping work pieces, after compression, thrust can regulate and automatically unclamp the rapid clamping fixture of pressing plate.
Summary of the invention
The present invention will provide a kind of automatic centering rapid clamping fixture, for solving the thrust fine setting after workpiece automatic centering clamping, compression and the technical problem of automatically unclamping pressing plate.
For achieving the above object, technical scheme of the present invention is: a kind of automatic centering rapid clamping fixture, comprise pressing plate, connecting rod, eccentric half nahlock, cylinder, connecting rod, between two connecting rods, be threaded connection, the middle lead that forms, the lead two ends of connecting rod are cross-under one block pressur plate respectively, on connecting rod, on the groove of bottom, have long lumbar hole, in each long lumbar hole, pass through eccentric half nahlock of the removable connection of bearing pin, on connecting rod, lower end is respectively equipped with adjusting bolt and locking nut, adjusting bolt bottom surface is connected with bearing pin contact, the bevel washer being socketed on connecting rod is housed above every block pressur plate, each eccentric half nahlock is provided with turning handle, and two turning handles are flexibly connected a connecting rod by pin respectively, and two connecting rods connect the piston rod of cylinder by pin.
Connecting rod between two block pressur plates is socketed with back-moving spring outward.When after clamping platen, between eccentric half nahlock and bevel washer, contact self-locking and be connected.
The invention has the beneficial effects as follows:
(l) in the time clamping, can pass through two bias, half nahlock quick centring clamping work pieces automatically with cylinder, and utilize bevel washer to regulate easily centering position, the angle of friction of bevel washer and eccentric half nahlock contact position is locked, in use, can not become flexible workpiece;
(2) for the workpiece with strain after compression, can finely tune by adjusting bolt and locking nut the thrust of eccentric half nahlock;
(3) because the connecting rod between two block pressur plates is socketed with back-moving spring outward, when unclamping after eccentric half nahlock, pressing plate is under action of reset spring, and automatic and workpiece unclamps.
Accompanying drawing explanation
Fig. 1 is structural upright schematic diagram of the present invention;
Fig. 2 is structural front view of the present invention;
Fig. 3 is the top view of Fig. 2;
In Fig. 4 Fig. 3 along B-B cutaway view.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment, the invention will be further described.
As shown in Figures 1 to 4, a kind of automatic centering rapid clamping fixture, comprises pressing plate 1, connecting rod 3, eccentric half nahlock 4, bevel washer 7, back-moving spring 6, bearing pin 8, turning handle 9, adjusting bolt 11, locking nut 12, connecting rod 13, cylinder 14, pin 15.
Between two connecting rods 3, be threaded connection, the middle lead that forms, the lead two ends of connecting rod 3 are cross-under one block pressur plate 1 respectively, on connecting rod 3 upper and lower part grooves, have long lumbar hole, in each long lumbar hole, pass through bias of the removable connection of bearing pin 8 half nahlock 4, connecting rod 3 upper and lower ends are respectively equipped with adjusting bolt 11 and locking nut 12, and adjusting bolt 11 bottom surfaces are connected with bearing pin 8 contacts, and every block pressur plate 1 is equipped with the bevel washer 7 being socketed on connecting rod 3 above; Each eccentric half nahlock 4 is provided with 9, two turning handles 9 of turning handle and is flexibly connected by pin 15 13, two connecting rods 13 of a connecting rod connect cylinder 14 piston rod by pin 15 respectively.
Outside connecting rod 3 between two block pressur plates 1, be socketed with back-moving spring 6.When after clamping platen 1, between eccentric half nahlock 4 and bevel washer 7, contact self-locking and be connected.
Use procedure of the present invention: in the time of the identical material of a collection of gauge thickness of processing, first the distance between two block pressur plates 1 of the present invention and workpiece 10 is carried out to initial adjustment by two connecting rods 3, to meet the spacing of eccentric half nahlock 4, can just can play the effect of friction compression by the eccentric throw of eccentric half nahlock 4 like this.And regulate when centering position, as long as rotate bevel washer 7.After clamping force regulates, open operated pneumatic valve, the piston rod of cylinder 14 move through backward connecting rod 13 by two turning handles 9 toward drop-down, eccentric half nahlock 4 is rotated, two block pressur plates 1 are under the effect of two bias half nahlocks 4, self-locking compresses bevel washer 7 and pressing plate 1, meanwhile, and also stressed compression of the workpiece 10 between two block pressur plates 1.When compression has after the workpiece 10 of strain, while finely tuning thrust as needs, can finely tune by adjusting bolt 11 thrust of eccentric half nahlock 4, finely tune and locked adjusting bolt 11 with locking nut 12 afterwards.When after completion of processing, the piston rod of cylinder 14 pushes away forward by connecting rod 13 and drives turning handle 9 upwards to rotate, and two bias, half nahlock 4 is rotated and loosen compression bevel washer 7, two block pressur plates 1 under back-moving spring 6 effects, automatic and workpiece 10 unclamps, and can take workpiece 10 away.
