Abstract

The invention discloses a machining method for the grooving of a shaft workpiece. A machining device comprises a main shaft; the main shaft is provided with a hydraulic three-jaw clamping disc; the hydraulic three-jaw clamping disc is connected with three clamping jaws; the hydraulic three-jaw clamping disc is coaxially and fixedly connected with a fixing base; the fixing base is provided with mounting grooves corresponding to the three clamping jaws in a one-to-one mode; a pressing cushion block is arranged in each of the mounting grooves; and the fixing base is further fixedly connected witha directional limiting block. According to the machining method for the grooving of the shaft workpiece, the hydraulic three-jaw clamping disc and as corresponding tool clamp are used for clamping shaft workpieces to be machined, and the grooving of the three shaft workpieces can be machined every time clamping is conducted, so that the machining efficiency is greatly improved; and during machining, the hydraulic three-jaw clamping disc is driven by the main shaft to rotate, and cutters only need to conduct corresponding feeding movement, so that the machining precision is high, the machiningefficiency is greatly improved, and the consistency of product processing is good.

Description

Technical field[0001]The invention belongs to the technical field of turning processing of metal material workpieces, and in particular relates to a processing method for grooving shaft workpieces.Background technique[0002]Shaft workpieces are usually cylindrical metal rods, such asfigure 1 The shown metal shaft workpiece 90 has a boss portion provided on its peripheral surface. The boss portion has symmetrical cutting planes 91 on its front and back sides, and the boss portion has symmetrical cutting grooves 92 on its upper and lower sides. When processing the groove 92, the existing processing method is to use a notch milling cutter and a bedroom milling machine for processing, such asfigure 2 As shown, it includes a rotating shaft 81 on which a notch milling cutter disk 82 is provided. A carriage 88 is provided beside the notch milling cutter 82, and a V-shaped fixing seat 86 and a directional tightening mechanism 87 are provided on the carriage 88. , The V-shaped fixing seat 86 ...
