Abstract
The invention relates to a quick clamping fixture. The quick clamping fixture comprises a pressing plate, a connecting rod, a T-shaped nut and an eccentric semicircular block, wherein the pressing plate is inserted in and connected to the middle part of the connecting rod; the lower end of the connecting rod is fixedly connected with a working table through the T-shaped nut; a through groove in the upper part of the connecting rod is rotationally connected with the eccentric semicircular block through a pin shaft; and the pressing plate is provided with an inclined washer coating the connecting rod. The connecting rod portion positioned between the pressing plate and the working table is coated with a return spring. A rotating handle is arranged on the eccentric semicircular block. After the pressing plate is tightly pressed, the eccentric semicircular block and the inclined washer are in contact self-locking connection. In clamping, a workpiece is quickly clamped through the eccentric semicircular block, the inclined washer is used for conveniently adjusting the clamping force, and the frictional angle in the contact place of the inclined washer and the eccentric semicircular block is used for locking; in the use process, the workpiece does not get loose; and as the connecting rod portion between the pressing plate and the working tabletop is coated with the return spring, after the eccentric semicircular block is released, the pressing plate is automatically released from the workpiece under the effect of the return spring.
Description
Technical field
The present invention relates to a kind of rapid clamping fixture, especially a kind of eccentric rapid clamping press plate.
Background technology
When metal cutting process, after Workpiece fixing, fixed to clamp with pressing plate, then used workpiece processing tool.Conventional fixation clip comes in addition fastening, and service efficiency is not high, and after repeatedly using, the hex nut place in bolt can produce distortion, last rounded state, causes spanner skid and cannot be wrenched; And screw thread is repeatedly engaged down with the screw thread of hex nut, can cause thread abrasion and rotten tooth, cause and cannot lock, service life is short.Chinese utility model patent number: 201120103422.3, disclose a kind of eccentric rapid clamping press plate, one end of pressing plate has indent feed groove, pressing plate is equipped with connecting rod, the lower end of connecting rod is connected with T-nut, its upper end is connected with the woodruff key of a bias, and the lower end of woodruff key contacts with pressing plate and connects, and woodruff key has been threaded handle.Although this pressing plate can realize Quick holding part, solve the defect that conventional fixation clip exists, but this pressing plate carrys 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 platen clamp workpiece and clamping displacement can only regulate by regulating connecting rod, extremely inconvenient, and, when clamping force is excessive, after woodruff key loosens, pressing plate cannot unclamp.Therefore, a kind of clamping force that facilitates is needed to regulate and the rapid clamping fixture that automatically can unclamp pressing plate.
Summary of the invention
The present invention will provide a kind of rapid clamping fixture, for solving the technical problem that clamping force regulates and automatically unclamps pressing plate.
For achieving the above object, technical scheme of the present invention is: a kind of rapid clamping fixture, comprise pressing plate, connecting rod, T-nut, eccentric half nahlock, cross-under pressing plate in the middle part of connecting rod, connecting rod lower end is fixedly connected with workbench by T-nut, be rotationally connected eccentric half nahlock by bearing pin in the groove of connecting rod top, the bevel washer be socketed on connecting rod is housed above pressing plate.
Back-moving spring is socketed with outside connecting rod between pressing plate and workbench.Eccentric half nahlock is provided with turning handle.When after clamping platen, eccentric half nahlock is connected with the Contact self-locking of bevel washer.
The invention has the beneficial effects as follows:
L (), when clamping, can pass through eccentric half nahlock Quick holding part, and utilize bevel washer to regulate clamping force easily, the angle of friction of bevel washer and eccentric half nahlock contact position is locked, and in use, can not loosen workpiece;
(2) owing to being socketed with back-moving spring outside the connecting rod between pressing plate and work top, 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 invention;
Fig. 2 is structural front view of the present invention;
Fig. 3 is the top view of Fig. 2;
Along A-A sectional view in Fig. 4 Fig. 3.
Detailed description of the invention
Below in conjunction with accompanying drawing and embodiment, the invention will be further described.
As shown in Figures 1 to 4, a kind of rapid clamping fixture, comprises pressing plate 1, connecting rod 3, T-nut 5, eccentric half nahlock 4, bevel washer 7, back-moving spring 6, bearing pin 8, turning handle 9.
Cross-under pressing plate 1 in the middle part of connecting rod 3, connecting rod 3 lower end is fixedly connected with workbench 2 by T-nut 5, is rotationally connected eccentric half nahlock 4 in the groove of connecting rod 3 top by bearing pin 8, and pressing plate 1 is equipped with the bevel washer 7 be socketed on connecting rod 3 above.
Back-moving spring 6 is socketed with outside connecting rod 3 between pressing plate 1 and workbench 2.Eccentric half nahlock 4 is provided with turning handle 9.When after clamping platen 1, eccentric half nahlock 4 is connected with the Contact self-locking of bevel washer 7.
Use procedure of the present invention: when the material that a collection of gauge thickness of processing is identical, first the distance between pressing plate 1 of the present invention and workpiece 10 is carried out initial adjustment by connecting rod 3, with the spacing of satisfied eccentric half nahlock 4, just the effect of stressed on friction can be played by the eccentric throw of eccentric half nahlock 4 like this.And regulate clamping force, as long as rotate bevel washer 7.After clamping force regulates, turning handle 9 is down pressed, pressing plate 1 is under the effect of eccentric half nahlock 4, and self-locking compresses bevel washer 7 and pressing plate 1, simultaneously, workpiece 10 under pressing plate 1 also stressed compression, when completion of processing, up push-jump fixed handle 9, pressing plate 1 is under back-moving spring 6 acts on, automatic and workpiece 10 unclamps, and can take workpiece 10 away.
