[0030] Working principle: In this embodiment, the present invention also proposes a method for using a quenching device for bearing processing, comprising the following steps:

[0031] Step 1: first, pour the quenching liquid into the liquid storage tank 1, then electrically connect the motor 5 and the electric push rod 11 to the external control device through wires, and then control the electric push rod 11 to shrink, thereby driving the stabilizing ring plate 12 to descend, and the stabilizing ring plate 12 is driven to descend by driving the mounting ring plate 13 and the rotating ring plate 14 to descend, and then the sliding sleeve 8 hinged to the inclined rod 15 is pushed on the vertical rod 7 by the descending rotating ring plate 14, so that the sliding sleeve 8 pushes the vertical rod 7 to tilt outward and unfold, so that the staff can place the bearing to be quenched on the vertical rod 7;

[0032] After the bearing ring to be quenched is placed on the same vertical rod 7, the separation mesh plate 9 is re-mounted on the vertical rod 7, and the bearing on the same vertical rod 7 can be separated. After the bearing ring to be quenched is placed, the anti-dropping block 20 is re-installed on the top of the vertical rod 7. When the vertical rod 7 is replaced to sleeve the bearing to be quenched, the lifting ring plate 4 can be horizontally rotated around the stabilizing tube 3 by toggling the vertical rod 7. When the lifting ring plate 4 rotates, the rotating ring plate 14 connected to the inclined tie rod 15 can be driven to rotate on the mounting ring plate 13. The vertical rod 7 on the lifting ring plate 4 can be rotated and replaced without the need for the staff to move the position, thereby improving the convenience and efficiency of the staff when placing the bearing to be quenched.

[0033] Step three, the electric push rod 11 is then controlled to extend, so as to drive the stabilizing ring plate 12 to rise, and the mounting ring plate 13 and the rotating ring plate 14 are driven to rise by the rising of the stabilizing ring plate 12, and then the sliding sleeve 8 hinged to the inclined tie rod 15 is pushed to slide on the vertical rod 7 by the descending rotating ring plate 14, so that the sliding sleeve 8 pulls the vertical rod 7 inwardly to be recovered into a vertical shape; when the vertical rod 7 is recovered into a vertical shape, it is convenient for the bearing supported on the top of the sliding sleeve 8 to descend on the vertical rod 7, so that the bearings to be quenched are all sunk into the liquid storage tank 1;

[0034] Step 4, the motor 5 is then controlled to drive the lead screw 6 to rotate, and the threaded tube 10 drives the stabilizing tube 3 and the lifting ring plate 4 to descend through the rotation of the lead screw 6, and the vertical rod 7 and the pushing assembly are driven to descend through the descending of the lifting ring plate 4, so that the quenching bearing on the vertical rod 7 sinks into the quenching liquid for cooling;

[0035] Step five, when the lifting ring plate 4 descends to the bottom of the liquid storage tank 1, it is convenient to make the abutting protrusion 19 on the top of the supporting ring plate 17 abut against the plug-in groove of the lifting ring plate 4, and then by toggling the top of the vertical rod 7 again, the movable ring plate 16 connected to the supporting ring plate 17 can be driven by the horizontally rotating lifting ring plate 4 to drive the scraper 18 to scrape the sediment on the bottom surface of the liquid storage tank 1, thereby preventing the sediment on the bottom surface of the liquid storage tank 1 from accumulating on the bottom surface of the liquid storage tank 1; then the lifting ring plate 4 is driven out of the liquid storage tank 1 by controlling the lifting mechanism, and after a period of water control operation, the regulating mechanism is controlled to unfold the vertical rod 7 again, and then the quenched bearing is pushed to the upper part of the vertical rod 7 by the sliding sliding sleeve 8, and then the staff can remove it from the vertical rod 7.

[0036] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
