According to the quick clamping press plate for the alignment, a workpiece can be quickly aligned and clamped by the two eccentric semicircular blocks, and by utilizing the inclined wafers, the alignment position is conveniently regulated, and the workpiece is locked by utilizing friction angles of contact parts of the inclined wafers and the eccentric semicircular blocks; after the workpiece with elastic deformation is clamped, the clamping forces of the eccentric semicircular blocks can be finely adjusted by the adjusting bolt and the locking nuts; a reset spring sleeves the exterior of the connection rod between the press plates and a working platform, so the press plates automatically loosen the workpiece under the action of the reset spring after the eccentric semicircular blocks are loosened.
Description
Technical field
The utility model relates to a kind of rapid clamping fixture, especially a kind of centering eccentric rapid clamping press plate of adjustable thrust.
Background technology
In metal cutting, add man-hour, behind workpiece location, with pressing plate, fixed to clamp, then use workpiece processing tool.Conventional fixation clip is with bolt, to come in addition fasteningly, 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, when 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 to clamp for workpiece centering, after compression, the rapid clamping fixture that thrust can regulate and automatically unclamp pressing plate.
Summary of the invention
The utility model is that a kind of centering rapid clamping press plate will be provided, for solving the thrust fine setting after the clamping of workpiece centering, compression and the technical problem of automatically unclamping pressing plate.
For achieving the above object, the technical solution of the utility model is: a kind of centering rapid clamping press plate, comprise pressing plate, connecting rod, eccentric half nahlock, 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.
Connecting rod between two block pressur plates is socketed with back-moving spring outward.Eccentric half nahlock is provided with turning handle.After clamping platen, between eccentric half nahlock and bevel washer, contact self-locking and be connected.
The beneficial effects of the utility model are:
(l) when clamping, can pass through two bias half nahlock energy quick centring clamping work pieces, and utilize bevel washer to regulate easily centering position, the angle of friction of bevel washer and eccentric half nahlock contact position is locked, and 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, after unclamping 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 utility model;
Fig. 2 is structural front view of the present utility model;
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 utility model is described in further detail.
As shown in Figures 1 to 4, a kind of centering rapid clamping press plate, 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.
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.
Outside connecting rod 3 between two block pressur plates 1, be socketed with back-moving spring 6.Eccentric half nahlock 4 is provided with turning handle 9.After clamping platen 1, between eccentric half nahlock 4 and bevel washer 7, contact self-locking and be connected.
Use procedure of the present utility model: when the identical material of a collection of gauge thickness of processing, first the distance between two block pressur plates 1 described in the utility model 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 by the eccentric throw of eccentric half nahlock 4 like this effect of friction compression.And while regulating centering position, as long as rotate bevel washer 7.After clamping force regulates, respectively turning handle 9 down to be pressed, two block pressur plates 1 are under the effect of eccentric half nahlock 4, and self-locking compresses bevel washer 7 and pressing plate 1, and meanwhile, the workpiece 10 between two block pressur plates 1 is stressed compression also.When compression has after the workpiece 10 of strain, while finely tuning thrust as needs, can, by the thrust of eccentric half nahlock 4 of adjusting bolt 11 fine setting, finely tune rear by locking nut 12 locking adjusting bolts 11.When completion of processing, up push-jump fixed handle 9, two block pressur plates 1 are under back-moving spring 6 effects, and automatic and workpiece 10 unclamps, and can take workpiece 10 away.
