Abstract

The invention discloses a heat treatment device for machine tool spindle production. The heat treatment device comprises a bottom plate, a spindle and a quenching box. A round hole is formed in the center position of a support. The side edge of the quenching box is fixedly connected with a clamping block. The clamping block is arranged on the edge of the round hole. The quenching box can rotate along the support. A positioning assembly is arranged on a carrier plate. A heating device is arranged above the carrier plate. According to the device, a plurality of blade plates are fixedly connectedto the inner wall of the quenching box, and therefore when the quenching box rotates, the blade plates further drive quenching liquid in a box body to rotate, during spindle quenching, the rotary quenching liquid acts on the spindle, the single-layer cross section of the spindle is quenched uniformly, and the actual quenching effect of the spindle is further improved. Meanwhile, the quenching liquid enters a water storage tank through a pipeline through a water pump and then enters an atomization sprayer to be sprayed to the spindle, the heated spindle is pretreated, and good application prospects are achieved.

Description

technical field

[0001] The invention relates to the field of machine tools, in particular to a heat treatment device for the production of machine tool spindles. Background technique

[0002] During the processing of the rotary shaft of the machine tool, it needs to be quenched to transform the cold austenite into martensite or bainite to obtain a martensite or bainite structure, so as to greatly improve the rigidity of the rotary shaft. Hardness, wear resistance, fatigue strength and toughness, etc., so as to meet the different needs of the rotary shaft.

[0003] The existing heat treatment device usually directly sprays lye to the surface of the rotary shaft body by spraying during use, which requires a large amount of lye to be sprayed onto the rotary shaft body, resulting in waste of lye and high quenching costs; secondly , it cannot spray lye on the bottom surface of the rotary shaft body, resulting in uneven cooling, incomplete cooling, affecting the cooling effect, a...
