Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance. In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted", "connected" and "disposed" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art. The following describes an embodiment of the present invention according to its overall structure.

Please refer to fig. 1-3, a fast switching clamp, including base jaw 1, tooth-shaped block 2, clamping jaw 3, dog 4, M10 modified screw 5, stop pin 6 and wedge 7, the top of base jaw 1 is provided with wedge 7, both sides of wedge 7 are connected with dog 4, the inside of dog 4 is provided with M10 modified screw 5, one end of M10 modified screw 5 is connected with tooth-shaped block 2, the top of dog 4 where is connected with stop pin 6, clamping jaw 3 is installed at the top of tooth-shaped block 2, the commonality of clamping jaw 3 is improved, so that clamping jaw 3 can be modified to be suitable for more standard chucks.

Please refer to fig. 1-3 again, the wedge block 7 is inclined downwards along the direction of the M10 modified screw 5, which facilitates the installation of the worker, improves the flexibility of the clamp, and the stop block 4 is connected with the tooth block 2 by the M10 modified screw 5, which facilitates the replacement and installation of the worker, and reduces the time required by the installation of the worker.

Please refer to fig. 2-3, the two stop pins 6 are arranged, and the two stop pins 6 are distributed along the length center line of the base jaw 1 in a mirror image manner, so that the clamping jaw 3 can be conveniently operated by the worker, the base jaw 1 is in a shape of Chinese character 'ao', the worker can conveniently install the base jaw 1 and the chuck, and the stability of the clamp during operation is ensured.

The working principle is as follows: when a worker replaces the clamping jaws 3, the worker firstly installs the base jaws 1 on the chuck, makes an anti-loose mark, and well performs periodic inspection, then when the worker adjusts the clamping size, the M10 modified screw 5 is loosened, the tooth-shaped block 2 is pulled to be disengaged from the tooth shape of the clamping jaws 3 along the wedge block 7, the clamping jaws 3 are moved to the corresponding scale positions, then the worker screws the M10 modified screw 5 in, the tooth-shaped block 2 is pushed to move along the inclined plane of the wedge block 7 to be engaged with the tooth shape of the clamping jaws 3, the adjustment of a single clamping jaw 3 is completed, if a plurality of clamping jaws 3 are arranged on one chuck, the actions are repeated, the application of the structure cancels the inconvenient operation caused by bolt connection, simultaneously the stroke of the clamping jaws 3 is increased, so that the clamp can be suitable for the sizes of more products, the investment of the clamp is reduced, the waste of resources is reduced, and simultaneously, clamping jaw 3 is built-in with the meshing position of profile of tooth piece 2, the dust pollution that the processing produced has been avoided, the clearance action when having reduced clamping jaw 3 and changing, and wedge and profile of tooth structure are used to locking structure, the meshing validity of the profile of tooth of clamping jaw 3 has been guaranteed, make the course of working more reliable and more stable, and M10 reforms transform screw 5's application, convenient and fast changes rotary motion for linear motion, the installation burden of staff has been alleviateed, and the cooperation of wedge structure is used, the effectual fit clearance that has eliminated, the vibrations that the course of working produced have been reduced, the stability of course of working has been improved.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
