The utility model content
The purpose of this utility model is exactly the defective for prior art, a kind of numerical-control crankshaft follow-up grinder is provided, it is that main bearing journal processing and crank-shaft link neck processing are realized integrated processing, need not just reach the purpose that bent axle or camshaft are processed by exchange device operation more.
The technical solution adopted in the utility model is: it comprises lathe bed and is installed in headstock cabinet, central frame mechanism, tailstock cabinet and emery wheel mechanism on the lathe bed, and described emery wheel mechanism comprises two abrasive machine devices that are respectively applied to machining crankshafts trunnion and crank-shaft link neck.
Further, be provided with support and the axially movable headstock mobile device of driving headstock cabinet bottom the described headstock cabinet.
Further, described headstock mobile device comprises the first track base of arranging on base, the base, and is connected with the first track base and drives the first track base first hydraulic jack in axial sliding on base.
Further, described the first track base connects one or more locking cylinders, the first track base is provided with the headstock, be provided with main shaft in the headstock, the part that main shaft stretches out the headstock is provided with anchor clamps, it is first top that front-end of spindle is provided with, and the described headstock one side is provided with the servomotor that the driving anchor clamps that are connected with anchor clamps rotate.
Further, described tailstock cabinet comprises the second track base, is installed in the guide rod in the second track base and is arranged on the guide rod tail end and the second hydraulic jack of drive leader axially-movable, described guide rod is the bicylindrical guide rod, one end of bicylindrical guide rod is fixed with slide plate, the other end is fixed on the guide rail sleeve in the second track base, is equipped with second top on the described slide plate.
Further, described central frame mechanism is arranged on the lathe by bracket support.
The utility model is simplified fast, with trunnion processing and the integrated processing of connecting rod neck processing realization of crank-shaft link neck, for production efficiency and the quality that improves equipment provides guarantee.
