[0028] After the back plate 5 and the containing body 51 are fixed, only one side of the first shell 11 is open.

[0029] Two first placement grooves 41 are symmetrically formed on the lower half of one side of the first housing 11 . The openings of the first placement grooves 41 face toward the back plate 5 .

[0030] A first through hole (not shown) is formed at the top of each first placement groove 41 , and the interior of the first through hole is connected to the interior of the corresponding first placement groove 41 .

[0031] The second housing 12 is disposed in the first housing 11 . One side of the second housing 12 is open, and the opening direction of the second housing 12 is the same as the opening direction of the first housing 11 .

[0032] The second housing 12 is slidably connected to the first housing 11 through a sliding block and a sliding groove. The second housing 12 moves along the opening direction of the first housing 11.

[0033] A moving assembly 2 is disposed between the first housing 11 and the second housing 12 , and the moving assembly 2 drives the second housing 12 to move.

[0034] The moving assembly 2 includes a plurality of retractors 21. The plurality of retractors 21 are fixed to the back plate 5 by bolts. The back plate 5 is connected to the housing 51 by bolts. It is convenient for operators to maintain the retractors 21.

[0035] During the actual movement, part of the second shell 12 is always located inside the first shell 11 .

[0036] The output ends of the plurality of retractors 21 are all fixed to the outer side of the second housing 12 .

[0037] A PLC controller (not shown) is arranged outside the equipment body 1 , and the PLC controller is electrically connected to a plurality of retractors 21 .

[0038] The bottom of the second shell 12 is configured as an inclined surface and a flat surface, and the inclined surface is configured near the opening of the second shell 12. The inclined surface facilitates the rapid collection of cooling water in one place.

[0039] The bottom plane of the inner wall of the second shell 12 is symmetrically fixed with two through pipes 4. Both through pipes 4 do not contact the sliding block and the sliding groove. The surface where the top of the through pipe 4 is located is coplanar with the surface where the bottom plane of the inner wall of the second shell 12 is located.

[0040] One end passes through the corresponding first through hole and extends into the corresponding first placement groove 41 .

[0041] A hose is provided at one end of the through pipe 4. The hose is connected to an external cooling water collection tank. A solenoid valve 42 is provided on each through pipe 4. The solenoid valve 42 is electrically connected to the PLC controller.

[0042] A T-shaped rod 3 is vertically arranged on the top of the plane, and a floating plate 31 is sleeved on the T-shaped rod 3. The T-shaped rod 3 limits the floating height of the floating plate 31. The surface where the top of the T-shaped rod 3 is located is located below the upper edge of the inclined plane.

[0043] A waterproof proximity switch is disposed on the lower half of one side of the inner wall of the second housing 12. When the floating plate 31 is at the highest point, the floating plate 31 faces the proximity switch. The proximity switch is electrically connected to the electromagnetic valve 42 and the PLC controller.

[0046] The implementation principle of the above embodiment is:

[0047] When the crankshaft needs to start cooling, the crankshaft is still placed on the induction hardening equipment body 1 .

[0048] The operator starts a plurality of retractors 21 through the PLC controller, and the plurality of retractors 21 push the second shell 12 to move, so that one side of the second shell 12 fits with one side of the induction hardening equipment body 1 , and at this time, a plurality of crankshafts to be cooled are located in the second shell 12 .

[0049] During cooling after quenching, the coolant drips from the plurality of crankshafts into the second housing 12 .

[0050] As more and more coolant flows, the float 31 starts to move upward along the height direction of the T-bar 3. When the float 31 moves to the highest point, the proximity switch is activated. The proximity switch activates two solenoid valves 42 through the PLC controller. The solenoid valves 42 open, and the coolant flows along the pipeline through the two through pipes 4 to the cooling water collection tank.

[0051] The solenoid valve 42 closes automatically after working for a period of time.
