Summary of the invention
The utility model be intended to solve the gear inclined-plane Drilling operation low precision that exists in known technology, bit grinding loss rate high-technology problem and provide a kind of simple in structure, easy to use, be installed stable, machining accuracy is high, and can extend the gear inclined-plane boring grab of drilling life of bit.
The utility model for the technical scheme that solves the technical problem that exists in known technology and take is: a kind of gear inclined-plane boring grab, comprise supporting seat, it is characterized in that: also comprise bushing plate, has the defining flange that coordinates with gear on the one side of bushing plate, described bushing plate is provided with several holes corresponding with beveled aperture to be processed position on gear, in described each hole, drill bushing is installed all, be provided with the some groups of hold-down mechanisms that are used for compressing bushing plate near described bushing plate, described hold-down mechanism is connected with described supporting seat.
The utility model can also adopt following technical scheme:
Described hold-down mechanism comprise the bolt that is connected with described supporting seat, with bolted pressing plate and the support column that is positioned at described pressing plate one side.
Described bushing plate is provided with locating hole, in described locating hole, alignment pin is installed.
Be provided with two groups of hold-down mechanisms that are used for compressing bushing plate near described bushing plate, described two groups of hold-down mechanisms are symmetrically set in the both sides of described bushing plate.
Described pressing plate is provided with the elongated slot that coordinates with described bolt.
Advantage and the good effect that the utlity model has are: because the utility model adopts as above technical scheme; namely design a kind of novel auxiliary clamp of holing of being used on the inclined-plane of gear; this fixture comprises drill bushing; drill bushing can effectively protect drill bit non-slip in the process of boring the inclined-plane; both effectively improved borehole accuracy; arranged the service life that can extend drill bit, and in addition, that the utility model also has advantages of is simple in structure, easy to use, mount is stable.
