Abstract

The invention discloses a heat treatment device for production of rotating shafts of a machine tool. The device comprises a quenching box and a liquid storage box, wherein the outer wall of the bottomof the quenching box is provided with a machine shell; the inner wall at the bottom of the machine shell is provided with a motor, and a fixing frame is arranged on the outer wall of one end of an output shaft of the motor; first electric push rods are arranged on the outer walls of the two sides of the fixing frame, clamping rings are arranged on the outer walls of one ends of the first electricpush rods, and rotating shaft bodies are clamped on the inner walls of one sides of the clamping rings; and a liquid outlet pipe is inserted into the outer wall of the top of the liquid storage box,and a corrugated pipe is inserted into the inner wall of one end of the liquid outlet pipe. According to the device, after the rotating shaft bodies are placed in the quenching box, lye can be sprayedto the surfaces of the rotating shaft bodies through a spray head on the outer wall of one side of a spray pipe so that the rotating shafts can be rapidly cooled, and meanwhile, people can adjust thedistance from the spray head to the rotating shaft bodies through stretching of a second electric push rod, so that the rotating shaft bodies are better cooled.

Description

technical field [0001] The invention relates to the technical field of rotary shaft production, in particular to a heat treatment device for the production of rotary shafts of machine tools. Background technique [0002] During the processing of the rotary shaft of the machine tool, heat treatment is required for the rotary shaft of the machine tool. During the heat treatment process of the rotary shaft of the machine tool, the front shaft needs to be placed in the quenching tank for water circulation cooling treatment. The purpose of quenching is to make the supercooled austenite Martensite or bainite is transformed to obtain martensite or bainite structure, and then combined with tempering at different temperatures to greatly improve the rigidity, hardness, wear resistance, fatigue strength and toughness of the rotary shaft, so as to meet Different use requirements for various mechanical parts and tools. [0003] After searching, the Chinese patent application number is C...
