Example three:

a cooling system is applied to the half-shaft quenching device 100 in the first or second embodiment, wherein, as shown in fig. 2, 8, 9 and 10, the cooling plate groups 30 are movably arranged in the quenching chamber 11 in a manner of folding and fitting with the side wall of the quenching chamber 11, and at least one cooling plate group 30 is arranged at each of the opposite wall ends of the quenching chamber 11.

The cooling plate group 30 is provided with a semicircular groove 31 for accommodating the half shaft, and cooling heads 32 are distributed on the inner annular surface of the semicircular groove 31.

The cooling system is provided with a trigger head 33 and an arc plate 34. The trigger head 33 is telescopically connected to the cooling plate package 30 on the same side of the semicircular groove 31. The trigger head 33 is in contact with an arc plate 34 positioned in the cooling plate group 30, the arc plate 34 is slidably arranged in the cooling plate group 30, a butt joint 341 is arranged on the arc plate 34, the butt joint 341 is communicated with a cooling cavity 35 in the cooling plate group 30, the butt joint 341 is staggered with a water inlet 361, the water inlet 361 is communicated with a flow dividing channel 36, and the flow dividing channel 36 is communicated with the cooling head 32.

As shown in fig. 11 and 12, when the half-axle shaft is cooled, the cooling plate groups 30 on both sides in the quenching chamber 11 are rotated, so that the trigger heads 33 on the cooling plate groups 30 are pressed against each other, the arc plates 34 in the cooling plate groups 30 are pushed, the butt joints 341 on the arc plates 34 are enabled to be communicated with the water inlets 361, and then water in the cooling chamber 35 enters the flow dividing channels 36 through the butt joints 341 and the water inlets 361, and finally is sprayed out from the cooling heads 32 to spray the half-axle shaft; after the cooling plate group 30 is rotated, the semicircular grooves 31 of the cooling plate group 30 are mutually attached to form a circle for accommodating the half shaft, and at the moment, the cooling head 32 on the inner annular surface of the semicircular groove 31 surrounds the half shaft to perform synchronous spray cooling on the circumferential surface of the half shaft. When not using, accomodate through folding, save space, be difficult for causing the interference, and when using, through expansion contact extrusion mode unblock cooling to coolant head 32 forms to encircle on the semi-axis, has realized realizing fast that no dead angle and synchronous spray cooling, consequently, the quenching effect is better.

As shown in fig. 9, the trigger head 33 and the cooling plate package 30 are directly provided with a return spring.

The cooling head 32 protrudes from the inner annular surface of the semicircular groove 31. By the convex arrangement, the sprayed oxide on the half shaft is not easy to block the cooling head 32 and can flow out from the opening below the two cooling plate groups 30.

Example four:

a half shaft quenching and cooling method applied to the half shaft quenching apparatus 100 in the first or second embodiment or the cooling system in the third embodiment, comprising the steps of:

when the half shaft needs to be quenched, firstly, the driving gear 152 and the driving gear 172 are simultaneously controlled to rotate, so that the first bearing plate 15, the second bearing plate 16 and the third bearing plate 17 synchronously rotate by a set angle, the gap between the first bearing plate 15 and the second bearing plate 16 is smaller than the diameter of the half shaft, and the radial distances between the first bearing plate 15, the second bearing plate 16 and the third bearing plate 17 and the axial line of the telescopic head 12 are equal;

Then, the half shaft is pushed to pass through the induction coil 20 through the telescopic head 12 and is matched with the joint 14 to fix the half shaft, and at the moment, the gap between the circumferential surface of the half shaft and the induction coil 20 is equal;

then, the first bearing plate 15, the second bearing plate 16 and the third bearing plate 17 are controlled to reset, and when the induction coil 20 is started to heat the half shaft, the induction coil 20 is controlled to slide along the half shaft so as to comprehensively heat the half shaft;

finally, after the half shafts are heated and the temperature is kept for a period of time, the half shafts are cooled by spraying through the cooling plate group 30.

The cooling process of the cooling plate group 30 is specifically as follows: the cooling plate groups 30 on the two sides in the quenching bin 11 are rotated, so that the trigger heads 33 on the cooling plate groups 30 are mutually extruded, the arc plates 34 in the cooling plate groups 30 are pushed, the butt joints 341 on the arc plates 34 are communicated with the water inlets 361, water flow of the cooling cavity 35 enters the flow dividing channel 36 through the butt joints 341 and the water inlets 361, and finally is sprayed out of the cooling heads 32 to spray the half shaft; after the cooling plate group 30 is rotated, the semicircular grooves 31 of the cooling plate group 30 are mutually attached to form a circle for accommodating the half shaft, and at the moment, the cooling head 32 on the inner annular surface of the semicircular groove 31 surrounds the half shaft to perform synchronous spray cooling on the circumferential surface of the half shaft.
