Heat treatment system for car universal joint cross shaft and treatment method thereof

Abstract

The invention discloses a heat treatment system for a car universal joint cross shaft and a treatment method thereof. The heat treatment system comprises a feeding mechanism, a normalizing mechanism,a conveying mechanism, a carburizing and quenching mechanism and a tempering mechanism. The carburizing and quenching mechanism comprises a working table, a supporting frame and a carburizing and quenching furnace. The top of a working table is fixedly connected with the bottom of the conveying mechanism. A loading mechanism is movably connected to the top of the conveying mechanism. The inventionrelates to the technical field of heat treatment systems. According to the heat treatment system for the car universal joint cross shaft and the treatment method thereof, a partition plate is fixedlyconnected between the top and the bottom of the inner wall of the loading table, thread rods are connected to the front and the back of the partition plate correspondingly, when the cross shaft is loaded and fixed, the fixing mechanism can be adjusted correspondingly according to the size of the cross shaft, and is applicable to multiple sizes of cross shafts, use is convenient, the loading mechanism does not need to be replaced frequently, the machining efficiency is improved, and the equipment investment cost of manufacturers is reduced.

Description

technical field [0001] The invention relates to the technical field of heat treatment systems, in particular to a heat treatment system and a treatment method for an automobile universal joint cross shaft. Background technique [0002] The universal joint cross shaft, also known as the ten-byte, is the universal joint. It is a machine that realizes variable-angle power transmission. It is used to change the position of the transmission axis. It is a joint component of the universal transmission of the automobile drive system. The cross-axis rigid universal joint is a non-constant velocity universal joint widely used in automobiles, allowing the maximum intersection angle of two adjacent axes to be 15°-20°. The cross shaft is one of the key components of the cross-axis rigid universal joint. Heat treatment refers to a metal thermal processing process in which materials are heated, kept warm and cooled in a solid state to obtain the desired structure and properties. During the...

Problems solved by technology

[0009] Aiming at the deficiencies of the prior art, the present invention provides a heat treatment system and treatment method for the cross shaft of the automobile universal joint, which solves the problem that the cross shaft of the automobile universal joint is directly carburized and quenched, and the structure of the cross shaft is easily deformed. When charging for carburizing and quenching, the charging mechanism cannot adjust the mechanism for fixing the cross shaft according to the size of the cross shaft, the scope of application is small, and the method of pushing the charging mechanism into the carburizing and quenching furnace is less safe.
