Background technology
At present, in hydraulic press industry, for the processing of piston rod end concave spherical surface, conventionally there is following several method for turning.The one, CNC Lathe Turning; The 2nd, hydraulic tracing control turning; The 3rd, formed turning tool turning; The 4th, the turning of both hands control method.In medium-sized and small enterprises, be not used because first three kind processing method production cost is high.And utilize both hands control method relative cost lower, but workman's technical merit is had relatively high expectations, and the sphere precision that car goes out is not high, surface quality is poor, production efficiency is low.
Summary of the invention
The problem existing for above-mentioned prior art, the utility model provides a kind of direct copy device of being convenient to machining piston bar concave spherical surface, and production cost is low, and the sphere precision and the surface quality that process are high.
To achieve these goals, the technical solution adopted in the utility model is: a kind of direct copy device of being convenient to machining piston bar concave spherical surface, comprises lathe tool, slip cutter hub; Also comprise convex template, dress broach shell, taper pin, adapter sleeve, sliding sleeve, taper shank; Described lathe tool is fixed in dress broach shell, and slip cutter hub is arranged in sliding sleeve, and slip cutter hub one end is welded to connect with dress broach shell, the other end is connected with adapter sleeve by taper pin, in adapter sleeve, be equipped with ball bearing, convex template is fixed on taper shank, and taper shank is connected with lathe tailstock simultaneously.
Further, slip cutter hub is connected with sliding sleeve by key, and two ends are screwed antirotation keys, and anti-skidding cutter hub rotates.
Further, between sliding sleeve and adapter sleeve, spring is housed.
Further, ball bearing is contained in adapter sleeve by bearing pin and spacer.
Further, convex template is fixed on taper shank by locating taper pin, bolt and packing ring.
Further, lathe tool is fixed in dress broach shell by housing screw.
The beneficial effects of the utility model are: install and fix the utility model, rely on the auto-feed of lathe saddle and the effect of spring force, ball bearing is done non-plane motion along convex template, thereby realizes the object of machining piston bar concave spherical surface; Change template, the utility model also can be processed the curved surface of other shape, has not only improved machining accuracy and surface quality, and has shortened the process-cycle, has reduced production cost.
