[0029] refer to Figure 2 A telescopic cylinder 2 34 is fixedly provided on the lower end surface of the slider 333, and a pneumatic clamp 35 is fixedly provided on the lower end surface of the piston rod of the telescopic cylinder 2 34. The height of the pneumatic clamp 35 is adjusted by the telescopic cylinder 2 34, and then the pneumatic clamp 35 is used to clamp the outer ring 5 of the bearing.

[0030] refer to Figure 3 A high-frequency quenching device 25 is symmetrically fixed on the surface of the workbench 1. The high-frequency quenching device 25 is a prior art. A quenching head 251 is installed on the outside of the high-frequency quenching device 25. The quenching head 251 corresponds to the position of the quenching component 2.

[0031] refer to Figure 3-Figure 5 The quenching assembly 2 includes a telescopic cylinder 21 and an annular frame 23. The telescopic cylinder 21 is fixed to the ground by bolts. A water collecting frame 22 is fixedly provided on the upper end surface of the piston rod of the telescopic cylinder 21. The annular frame 23 is arranged above the water collecting frame 22.

The annular frame 23 is supported by the connecting rods 24. The outer side surface of the annular frame 23 is provided with a water inlet 231. The external water injection device can be connected to the water inlet 231 through a water pipe to inject water into the annular frame 23. The water injection device is a prior art, and its structure and principle are not described here.

[0033] refer to Figure 3-Figure 5 A plurality of water spray holes 232 are provided on the inner ring surface of the annular frame 23.
