In order to achieve the above purpose, the utility model provides a following technical scheme: the utility model provides a high-efficient core hobbing clamp that rises of extensive applicability, includes the base that can be connected with the gear hobbing machine, wear to be equipped with the dabber in the base, the dabber lower part be provided with can with the butt piece of base butt, be provided with elasticity wave spring on the butt piece, the upper portion of dabber is provided with the toper section, the cover is equipped with the tight cover that rises that a plurality of can with tooth embryo hole butt on the toper section, the top threaded connection of dabber has the cap nut, it is equipped with the clamping ring to go back to cover on the tooth embryo.
Preferably, an O-shaped sealing ring is arranged between two adjacent tensioning sleeves.
Preferably, the base is connected with the cushion block through a bolt, an inner sleeve sleeved on the mandrel is arranged on the cushion block, a placing groove is formed in the inner sleeve, and the plurality of tensioning sleeves are arranged in the placing groove.
Preferably, the base is provided with a threaded through hole, a fixing groove is formed in the position, corresponding to the threaded through hole, of the mandrel, and a fixing bolt capable of being abutted to the fixing groove is fixedly arranged at the position of the threaded through hole.
Preferably, the pressing ring is fixedly connected with the cap-shaped nut through a screw.
The utility model has the following advantage for prior art, its use is, fixes the base on the gear hobbing machine, realizes the fixed to tooth embryo hole through the tapering of dabber upper end toper section and the interior taper hole of the tight cover that rises. When the gear blank is locked, only the hexagon socket head cap nut at the upper end needs to be screwed, the mandrel is pulled upwards, the gear blank and the tensioning sleeve can be in interference fit and can fix the gear blank, the pressing ring is pressed, and the gear hobbing of the gear hobbing machine is started. And removing the pressing ring after rolling, unscrewing the hexagon socket head cap nut at the upper end, enabling the elastic wave spring at the lower end of the mandrel to play a role in preventing loosening, enabling the tensioning sleeve bearing bush to contract inwards, and releasing locking between the processed gear and the tensioning sleeve, so that the gear can be disassembled and replaced to continue the next cycle processing.
The advantage of this scheme is, it can use on any gear hobbing machine to provide a strong adaptability to can improve gear machining precision greatly, by the lathe that originally can only process 8, 9 level precision gears, improve to can process 5, 6 level precision gears, this anchor clamps clamping is convenient, and production efficiency is higher.
