The invention discloses a constant-temperature control device of automotive half shaft quenching liquid. The constant-temperature control device of the automotive half shaft quenching liquid comprises an oil tank (1), a cold water inlet (2), a hole type partition plate (3), a half shaft (4), a front frame (5), a back frame (6), a U-shaped cold water pipe (7), cold liquid (8), an oil temperature control meter (9) and a cold water outlet (10); the hole type partition plate (3) is welded on the middle part of the oil tank (1); the cold water inlet (2), the cold water outlet (10) and the U-shaped cold water pipe (7) are mounted on two ends of the oil tank (1) near the underneath of the hole type partition plate (3); the front frame (5) and the back frame (6) are mounted on the hole type partition plate (3) in the oil tank (1); the temperature of the cold liquid (8) is controlled in the range of 45-60 DEG C; the oil temperature control meter (9) is mounted on the side of the oil tank (1) and automatically adjust the temperature of the cold liquid (8) when the temperature of the cold liquid (8) exceeds the range of 45-60 DEG C; a cooling medium in the U-shaped cold water pipe (7) is condensation circulating water.
Description
technical field [0001] The invention relates to a control device, in particular to a constant temperature control device for an automobile half shaft quenching fluid. Background technique [0002] The automobile half-shaft needs to be quenched to improve the overall mechanical properties and wear resistance. In the traditional quenching process, the coolant oil recovery water is used as the medium, and water is used as the coolant medium. The hardness of quenching is relatively high, but due to the extremely cold strength of water High, cracks and hidden cracks are easily produced at the step part and the junction of the rod part and the disc part. When the car is running under harsh conditions, the axle may break and the wheel will fall off, causing the car to overturn or cause personal injury. According to the research and test of the company's scientific and technical personnel, the quenching coolant was changed to 20W mechanical oil, and the effect of quenched automobile...
