Detailed description of the invention
Referring to figs. 1 to Fig. 3, the utility model relates to a kind of wedge structure grip device, comprise the base 1 in the middle part of in the of with cavity, the upper end of described base is provided with the wedge shape opening with cavity connects, two pieces of symmetrical wedges 2 laid are slidably connected in described wedge shape opening, the bottom of described wedge is connected to one and is positioned on the elevating bracket 3 of base cavity pocket, described elevating bracket both sides are threaded through an and longitudinal screw mandrel 4 that is protuberate basic unit upper surface, upper end hinged with base respectively, the base end face being positioned at cavity bottom offers a conduit 5, hinged with base respectively and the second gear 6 that the number of teeth is identical and the 3rd gear 7 is provided with in described conduit, also be provided with in described conduit and be connected respectively with two longitudinal screw mandrels and identical the one 8 and the 4th gear 9 of the number of teeth, described first gear and the second gears meshing, described second gear is through the 3rd gear and the 4th gears meshing, the base being positioned at wedge both sides is connected with a catch 11 respectively by lock-screw 10, the outer end of described catch is to wedge infolding, to form notch, the both sides of described wedge are respectively equipped with the extension 12 installed in notch.
For the ease of operation screw mandrel, longitudinal screw mandrel upper end one of is wherein connected with an operating grip 13.
In order to meet being slidably connected between wedge and elevating bracket, upper described elevating bracket being provided with chute 14, bottom described wedge, being provided with the slide block 15 installed in chute.
Be connected with bottom bay for the ease of this chuck, be respectively equipped with one in the both sides, bottom of above-mentioned base in order to bolted duct 16.
Specific implementation process: this device is connected on a certain work housing by bolt duct, then hand-held operation handle, by handle, longitudinal screw mandrel is rotated, because the bottom of longitudinal screw mandrel is by first, second, 3rd and the 4th gear synchronous drives another longitudinal screw mandrel rotating in same direction, thus elevating bracket is declined, the elevating bracket declined drives two wedges to separate along notch, then the object of required clamping is put between two wedges, after putting well, operating grip makes it reverse again, the handle of reversion drives elevating bracket to rise by leading screw, owing to adopting wedge-like opening structure, gap between two wedges can reduce, gripped object can be clamped.When gripped object drives wedge to continue up, because wedge is installed on wedge shape opening, therefore gripped object instead can be tighter by what clamp.
Although specifically show in conjunction with preferred embodiment and describe the utility model; this technical scheme method and access of specific implementation is a lot; the above is only preferred embodiment of the present utility model; but those skilled in the art should be understood that; not departing from the spirit and scope of the present utility model that appended claims limits; can make a variety of changes the utility model in the form and details, be protection domain of the present utility model.
