Description
Technical field
The utility model relates to a kind of inner arc shaping device, particularly is applied in the device that rapid and convenient on the engine lathe is processed circular arc in the various differences.
Background technology
At present, the way that circular arc usually adopts in the processing on engine lathe is to process by skilled worker's level and model detection or by pattern to finish, and not only machining accuracy is not high if process with template method, and wastes time and energy, and it is stable that quality can not keep.If with pattern method processing, different interior circular arcs otherwise with pattern process, efficient is lower.
Summary of the invention
In order to overcome above problem, the utility model provides a kind of inner arc shaping device, and it can process the interior circular arc of different-diameter convenient, fast, exactly.
The utility model has adopted following technical scheme: a kind of inner arc shaping device, it comprises drive link, the side of drive link is a bearing, one end of drive link is connected with rotation hand wheel, the other end of described drive link is provided with worm screw, be provided with the rotation tool rest in the worm screw side, the top of rotating tool rest is set to pressing plate, accompanies cutter between the upper plate of pressing plate and the lower plate, the bottom of rotating tool rest is provided with turning cylinder, turning cylinder is positioned at the pedestal below the rotation tool rest, is with worm gear on turning cylinder, and worm gear is connected with turning cylinder, worm and wheel contacts, worm and wheel is a drive state, and worm screw drives worm gear and rotates, and worm gear drives turning cylinder successively, pressing plate and cutter rotate.
The upper and lower of described pedestal all is provided with bearing, and the two bearings position is corresponding, and turning cylinder is positioned at two bearings.Be connected for key between described worm gear and the turning cylinder.
The utlity model has following beneficial effect: the utility model is contained on the small tool, rotate arc track in the generation by the driving-belt moving knife tool between the worm and gear, thereby process needed circular arc, so not only convenient and swift, the machining accuracy height, and applied widely, can on machine tool, can be used widely.The utility model only need just can required processing arc radius by adjusting point of a knife to the distance at rotating shaft center, thus can reach processing different in the circular arc requirements, regulate more convenient.
