Description

Technical Field

[0001] The invention relates to the technical field of motor shaft processing, and in particular to a quenching and tempering device and a processing method thereof in motor shaft processing. Background Art

[0002] The motor shaft needs to be quenched and tempered during the processing process. The quenching treatment is to heat the motor shaft to a certain temperature, keep it warm for a period of time, and then quickly cool it to change its internal structure, thereby improving its performance. The tempering treatment is to heat the motor shaft to a certain temperature again after quenching and cooling it. During the heating process, the atoms inside the motor shaft will rearrange to form a new structure, thereby improving the toughness and stability of the motor shaft and extending its service life. However, the existing quenching and tempering devices need to manually take out the motor shaft for cooling during use, which is inconvenient and easy to injure the staff due to the high temperature of the motor shaft when taking out the motor shaft, posing a great safety hazard.

[0021] Compared with the prior art, the invention has the following advantages:

[0022] 1.

When taking it out, start the electric telescopic rod to drive the motor shaft out of the heat treatment box. No manual operation is required. Tempering is the same operation, which is very convenient.

[0023] 2. After quenching is completed, as the bearing frame is moved out, it drives the motor shaft to move in the direction of the bearing matching end plate. During the movement, the driving bearing plate will contact the supporting linkage bearing plate, and then drive the supporting linkage bearing plate to move, so that the movable pipe sleeve can be driven to move, and the sealed connection between the air supply pipe and the air inlet sleeve can be achieved, so that the cooling air can be transported to the bearing frame and blown to the motor shaft from all sides to quickly cool it. There is no need to manually transfer the motor shaft for cooling operation, which is safer and more convenient.

[0024] 3. In addition, when the bearing frame moves over the heat-insulating movable plate, it will drive the heat-insulating movable plate to move along with the movement of the supporting linkage carrier plate, so that the heat-insulating movable plates are closed together. This can play a certain role in blocking the heat dissipated from the heat treatment box, preventing it from moving in the cooling direction of the motor shaft and affecting the cooling efficiency of the motor shaft. After the tempering treatment is completed, it is only necessary to start the electric telescopic rod to drive the bearing frame out of the heat treatment box to allow the motor shaft to cool naturally and slowly.

[0048] A motor shaft quenching and tempering processing method comprises the following steps:

[0049] Step 1: Placement of the motor shaft: Place the motor shaft in the carrying frame 24;

[0050] Step 2: Transfer of the motor shaft: Start the electric telescopic rod 161 to drive the motor shaft to move into the heat treatment box 11;

[0051] Step 3: Quenching of the motor shaft: The heat treatment box 11 heats the motor shaft to achieve quenching;

[0052] Step 4: Rapid cooling after quenching: After quenching is completed, the electric telescopic rod 161 is started to drive the bearing frame 24 to move while connecting the air inlet sleeve 26 with the air supply pipe 63 to cool the motor shaft;

[0053] Step 5: Tempering the motor shaft: After cooling, the electric telescopic rod 161 is started to drive the motor shaft to enter the heat treatment box 11 again, and the motor shaft is heated again for tempering treatment;

[0054] Step 6: Natural cooling: After the motor shaft is tempered, it is removed from the heat treatment box 11 for natural cooling.

[0055] When the motor shaft is quenched, it is placed in the bearing frame 24 and supported at both ends of the motor shaft by the support plate sleeve 25, and then the electric telescopic rod 161 is started to drive the bearing frame 24 to move into the heat treatment box 11. When it moves into the heat treatment box 11, the driving sleeve 22 is in contact with the movable connecting block 35. As the bearing frame 24 moves further, the driving sleeve 22 will drive the movable connecting block 35 to move, and then the first connecting rod 34 will drive the two boxes to move.

At this time, the supporting slide rail rod 14 is inserted in the second matching rod groove 50, so that when the motor shaft is cooled, the heat emitted by the heat treatment box 11 can be prevented from moving toward the motor shaft. With the movement of the supporting linkage carrier plate 4, the plug-in linkage column 67 is driven to move under the restriction of the driving slideway 172, and then the movable sleeve 64 can be driven to move. The air inlet sleeve 26 moves in the direction so that the connecting pipe ring 65 on the movable pipe sleeve 64 is inserted into the connecting pipe groove 261, thereby realizing a sealed connection between the air inlet sleeve 26 and the air supply pipe 63, so that the cooling air can be transported to the bearing frame 24 and blown from the blowing pipe 27 to the motor shaft to realize rapid cooling of the motor shaft. After cooling, when tempering the motor shaft, the electric telescopic rod 161 is started again to drive the bearing frame 24 to move to the heat treatment box 11 again to temper the motor shaft. After tempering, it is moved out of the heat treatment box 11 for natural cooling.
