Processing device for half-shaft hardening machine tools

Abstract

The invention belongs to the technical field of machining, and particularly discloses a machining device for a half-shaft quenching machine tool. The machining device comprises a fixing frame, telescopic rods, a V-shaped plate, a press roller, a thread roller, a water spraying pipe, a first motor and a second motor. The press roller, the thread roller and the water spraying pipe are distributed on the circumferential face of a half shaft. The center position of the press roller is connected with a rotation shaft, and the rotation shaft is rotationally connected to the telescopic rods. A bent part of the V-shaped plate is fixed to the fixing frame, and the opening end of the V-shaped plate is located below the half shaft. A threaded groove is formed in the surface of the thread roller, the surface of the water spraying pipe is a frosting face, the thread roller is rotationally connected to one side of the V-shaped plate, and the water spraying pipe is fixed to the other side of the V-shaped plate. One end of the water spraying pipe is closed, the other end of the water spraying pipe communicates with a water passing pipe, and water outlet holes are formed in the surface of the water spraying pipe. The machining device is used in the half-shaft quenching machine tool, oxide skin on the surface of the half shaft can be thoroughly removed in the quenching process, and the half shaft can be effectively prevented from deforming in the quenching process.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and in particular relates to a processing device for a half-shaft quenching machine tool. Background technique [0002] The half shaft, also called the drive shaft, is the shaft that transmits torque between the gearbox reducer and the drive wheels. Quenching is required during the production and processing of the half-shaft, that is, the half-shaft workpiece is heated to an appropriate temperature and kept for a period of time, and then immersed in a quenching medium for rapid cooling. Existing quenching of the half shaft is carried out on the quenching machine tool. The quenching machine tool of the half shaft is provided with a water spray device for spraying cooling water to the half shaft workpiece and an inductor for heating the above half shaft workpiece. The water device includes a water spray box and a water spray nozzle that supplies water to the water spray box; the wate...

AI Technical Summary

Problems solved by technology

Moreover, the surface of the half-shaft workpiece is oxidized after being heated to form an oxide skin. When the half-shaft is cooled, part of the oxide skin peels off, and the oxide skin is scattered around, causing subsequent cleaning troubles. The surface affects the appearance of the workpiece. After quenching, the half shaft needs to be polished to remove the oxide skin on the surface.

Straightening, grinding and other processes are required after the half shaft is quenched, which is very troublesome, the labor intensity of the workers is high, and the production efficiency is seriously affected
