[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts belong to the protection scope of the present utility model.
[0021] The present utility model provides a technical solution. Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , an automatic quenching device for automobile shaft parts, including: a quenching tank 1, an opening plate 2 and a stirrer 3. Quenching oil is stored inside the quenching tank 1 to perform quenching processing on the shaft body. The opening plate 2 can prevent external debris from entering the inner bottom of the quenching tank 1 when the shaft body is quenched. The stirrer 3 is a common stirring device in the prior art and can drive the quenching oil to move, increasing the heat dissipation speed.
[0022] The opening plate 2 is assembled inside the quenching tank 1, and the stirrer 3 is assembled at the bottom of the opening plate 2. Fire extinguishing mechanisms 4 are connected to both ends of the quenching tank 1. The fire extinguishing mechanism 4 includes a hollow block 41. The hollow block 41 is hollow-designed and can store quenching oil inside. The hollow block 41 is slidably connected to the quenching tank 1. A single-axis driver 44 is assembled at the top of the hollow block 41. The single-axis driver 44 is a common single-axis driving device in the prior art and can drive the hollow block 41 to move, and the single-axis driver 44 is connected to the quenching tank 1.
[0023] A piston rod 46 is slidably connected inside the hollow block 41, and the other end of the piston rod 46 is connected to a frame 45. The frame 45 can support the piston rod 46, and the frame 45 is connected to the quenching tank 1. A long pipe 47 is communicated with the outside of the hollow block 41, and the other end of the long pipe 47 is communicated with a hollow box 48.
[0024] The hollow box 48 is communicated with the quenching tank 1. Partition plates 42 are embedded at the top and bottom of the hollow block 41. The partition plates 42 include a heat insulation plate and a heat dissipation plate. The heat insulation plate and the heat dissipation plate are respectively assembled at the bottom and top of the hollow block 41. The partition plates 42 can prevent the quenching oil inside the quenching tank 1 from conducting heat to the quenching oil inside the hollow block 41, and can also increase the heat dissipation speed of the quenching oil inside the hollow block 41. The heat insulation plate can be glass fiber, asbestos, rock wool, silicate, etc., and the heat dissipation plate can be a copper plate.
[0025] Inside the hollow block 41, a silicone rubber block 43 is embedded. And exhaust holes are provided on the outside of the silicone rubber block 43. The silicone rubber block 43 can fit with the lifting chain of the lifting tool through its own deformation ability, reducing the contact between oxygen and the quenching oil inside the quenching tank 1. The piston rod 46 includes a piston. Inside the piston, a guide plate is embedded. The guide plate is slidably connected to the hollow block 41. On both sides of the outside of the piston, cross arms are connected. The cross arms are connected to the frame 45. A sealing sleeve is connected at the junction of the cross arm and the hollow block 41. The piston rod 46 can move linearly inside the hollow block 41, and then press the quenching oil back into the interior of the quenching tank 1.
[0026] Inside the hollow box 48, a filter plate 49 is embedded. Holes are evenly distributed on the outside of the filter plate 49. The hollow box 48 can prevent impurities inside the quenching tank 1 from entering the interior of the fire extinguishing mechanism 4. The long tube 47 includes a corrugated tube. At both ends of the corrugated tube, heat-insulating tubes are communicated. The heat-insulating tubes are respectively communicated with the hollow box 48 and the hollow block 41. The long tube 47 is elastic and can be telescoped, and can also prevent the quenching oil inside the quenching tank 1 from conducting heat to the long tube 47.
[0027] In this solution, first, the lifting tool is used to drive the vehicle axle part to rise, and the heated vehicle axle part is placed into the interior of the quenching tank 1, and the vehicle axle part is quenched by the quenching oil.
[0028] If the quenching oil catches fire, drive the single-axis driver 44 to drive the hollow block 41 to move. The two hollow blocks 41 move relatively to seal the top of the quenching tank 1, preventing the quenching oil from continuing to contact with oxygen, and then completing the fire extinguishing. At the same time, when the partition plate 42 moves, through the cooperation of the piston rod 46, the quenching oil stored at one end of the hollow block 41 away from the quenching tank 1 is discharged into the interior of the quenching tank 1 through the long tube 47 and the hollow box 48, reducing the temperature of the quenching oil inside the quenching tank 1, and then extinguishing the fire through cooling.
[0029] When the vehicle axle part is being quenched, if the quenching oil catches fire, the added fire extinguishing mechanism 4 automatically disconnects the contact between the quenching oil and oxygen, and then extinguishes the flame, thus preventing the flame from continuously burning the lifting tool or the device and affecting the service life of the device, and at the same time preventing the flame from harming the staff. At the same time, by injecting cooled quenching oil into the interior of the quenching tank 1, the temperature of the quenching oil inside the quenching tank 1 is reduced to complete the fire extinguishing, greatly improving the extinguishing speed of the fire extinguishing mechanism 4 for the flame.
