For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of expanding-contracting type gear hobbing mold, comprise base, on base, be provided with a brace table for supporting and location gear ring to be processed, described brace table has an inner chamber, in this inner chamber, being provided with can be from the annular means for belt tension of the outside lateral magnification of described lumen centers, annular means for belt tension lateral surface is connected with the medial surface tensioner of described gear ring to be processed, in inner chamber, be provided with the hydraulic system that drives annular means for belt tension motion, described hydraulic system forms by being fixed on the hydraulic jack of supporting the platform bottom and the piston rod be connected with the annular means for belt tension medial surface of hydraulic jack both sides respectively.
Above-mentioned expanding-contracting type gear hobbing mold, described annular means for belt tension top are provided with the detent mechanism for vertically fixing gear ring to be processed.
Above-mentioned expanding-contracting type gear hobbing mold, described detent mechanism by self-supporting platform bottom extend upward setting backstay, pass that backstay acts on the positioning gland on gear ring to be processed and the clamp nut be connected with the backstay screw top be located on positioning gland forms.
Above-mentioned expanding-contracting type gear hobbing mold, the bottom of described annular means for belt tension and brace table bottom are connected by track-type facilities.
Above-mentioned expanding-contracting type gear hobbing mold, be provided with easy-to-dismount suspension ring on described positioning gland.
The advantage of the utility model expanding-contracting type gear hobbing mold is: add man-hour for the gear ring gear hobbing, clamping for gear ring in enormous quantities, in clamping process, do not need to use the spanner tighten the screws, time saving and energy saving, efficiently solving in the processing of current gear ring gear-hobbing machine loads and unloads gear ring at every turn and all must turn on hold-down nut, not only waste time and energy, and under manually-operated, the elasticity of each hold-down nut is inconsistent, affect the problem of gear ring crudy, and hydraulic power is arranged on outside mold, avoided traditional tension tool to leak because of the wearing and tearing build-up of pressure that repeatedly stretches, affect expanding force, cause the generation of the problems such as machining accuracy reduction, and the workpiece processed can directly take out, realized the gapless location of fixture and inner hole of workpiece, positioning precision is good, location rapidly, the utility model is simple in structure, gear hobbing efficiency is high.
