Abstract

The invention discloses a processing method for grooving a shaft workpiece. The processing device includes a main shaft, the main shaft is provided with a hydraulic three-jaw chuck, and the hydraulic three-jaw chuck is connected with three clamping claws, and the hydraulic three-jaw chuck is coaxial A fixed seat is fixedly connected, and the fixed seat is provided with installation grooves corresponding to the three clamping claws one by one, and a pressing spacer is arranged in the installation groove, and the fixed seat is also fixedly connected with a directional limit block. The invention utilizes the hydraulic three-jaw chuck and the corresponding tooling fixture to clamp the shaft workpiece to be processed, and each clamping can process the grooving of three shaft workpieces, which greatly improves the processing efficiency. When the jaw chuck rotates, the tool only needs to move in the corresponding feed, the machining accuracy is high, 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 cutting grooves of shaft workpieces. Background technique [0002] Shaft workpieces are usually cylindrical metal rods, such as figure 1 As shown, a metal shaft workpiece 90 is provided with a boss portion on its peripheral surface. The front and rear sides of the boss portion have symmetrical cutting planes 91 , and the upper and lower sides of the boss portion have symmetrical cutting grooves 92 . When processing this grooving 92, existing processing method is to adopt notch milling cutter and horizontal milling machine to process, as figure 2 As shown, it includes a rotating shaft 81, on which a notch milling cutter disc 82 is arranged, and a carriage 88 is arranged beside the notch milling cutter disc 82, and a V-shaped fixing seat 86 and a directional tightening mechanism 87 are arranged on the car...
