Description

Technical Field

[0001] The present invention relates to the field of motor shafts, and specifically to a heat treatment device for machining motor shafts. Background Art

[0002] The shaft is an important part in a motor. As the link for electromechanical energy conversion between the motor and the equipment, it supports rotating components, transmits torque, and determines the relative position of the rotating components with respect to the stator. Therefore, the motor shaft must have reliable strength and stiffness to ensure the realization of the preset design function. When machining the motor shaft, it needs to be quenched by a heat treatment device, so that the strength of the motor shaft can be increased after quenching. When the existing heat treatment device for motor shafts is in use, the motor shaft is fixed by a fixing mechanism. By moving the semi-circular shell, the two semi-circular shells are spliced together to wrap the motor shaft. The heating strip is started to perform heat treatment on the motor shaft, reducing heat loss and enabling the motor shaft to quickly heat up. After the heat treatment is completed, by moving the water suction pipe, the water outlet pipe on the water suction pipe is aligned with the motor shaft below, and the water pump is started to pump the water in the water storage tank into the water suction pipe and then sprayed on the motor shaft through the water outlet pipe to cool the motor shaft and improve its performance. However, when cooling, the two semi-circular shells need to be separated, which will cause a large amount of heat loss in the semi-circular shell, resulting in a large amount of heat waste. To solve this problem in the prior art, a vacuum pumping technology is used to pump the heat into a heat preservation cavity, and when heat treatment is performed again, the heat is pumped back into the heat treatment cavity. However, retaining the heat has a high usage cost, and when the heat is in the heat preservation cavity, the heat cannot play its role, which will reduce the utilization efficiency of the heat. Secondly, after the cooling water cools the heat-treated motor shaft, the temperature of the cooling water will gradually increase. At this time, a cooling mechanism needs to be used to cool the cooling water, but this will waste the heat in the cooling water, resulting in heat waste. For this reason, we propose a heat treatment device for machining motor shafts. Summary of the Invention

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] 1. After a motor shaft is heated in the present invention, the working plate is driven to rotate 90 degrees by the adjustment assembly, so as to change the positions of the four clamping assemblies clamping the four motor shafts. The preheated motor shaft moves between the upper shell and the lower shell, the heated motor shaft moves between the upper box and the lower box, the cooled motor shaft moves to the loading and unloading position, and the newly loaded motor shaft moves above the preheating assembly; and during the rotation of the working plate, the upper shell and the lower shell will be in contact with the working plate for a long time, which can avoid a large amount of heat loss in the upper shell and the lower shell, and the heat in the upper shell and the lower shell can quickly heat the next motor shaft.

[0015] 2. When the present invention is in use, the cooling water in the cooling water tank can be pumped through a water pump to cool down the heated motor shaft. After use, the cooling water will be discharged back into the cooling water tank along the water pipe. At this time, the heat conducting member will conduct the heat in the cooling water, and the semiconductor refrigeration sheet will absorb the heat of the heat conducting member to reduce the temperature of the heat conducting member, so that the heat conducting member can effectively and continuously conduct the heat in the cooling water, and then the temperature of the cooling water can be reduced. And in this process, when the cooling water flows in the water outlet pipe, it will drive the second fan blade to rotate. The rotation of the second fan blade will drive the rotating shaft to rotate. The cooling water after cooling the motor shaft will be discharged into the cooling water tank through the water pipe. In this process, it will drive the first fan blade to rotate, and the rotation of the first fan blade will also drive the rotating shaft to rotate. The effective rotation of the rotating shaft can drive the exhaust fan blade to rotate, and the exhaust fan blade will accelerate the upward movement of the heat released from the heat dissipation end of the semiconductor refrigeration sheet to avoid heat accumulation. At the same time, the upward movement of the heat will pass through the motor shaft, and the unheated motor shaft can be preheated first, so as to preheat the unheated motor shaft by using the heat released by the cooling water. And the effective rotation of the rotating shaft can also drive the stirring blade to rotate, and the rotation of the stirring blade will continuously stir the cooling water, making the temperature of the cooling water in the cooling water tank uniform, so that the water temperature of the cooling water in the cooling water tank can be effectively reduced. Simply put, by using the circulating flow of the cooling water, the heat released from the heat dissipation end of the semiconductor refrigeration sheet is effectively driven to accelerate upward movement, avoiding heat accumulation, realizing the preheating of the motor shaft, and at the same time realizing the self-stirring of the cooling water in the cooling water tank, so that the water temperature of the cooling water in the cooling water tank can be effectively reduced.

[0016] 3. When the working disk rotates and the motor shaft is replaced between the upper shell and the lower shell, the second heat insulation plate and the first heat insulation plate will seal the top and bottom of the installation slot where the preheated motor shaft is located, avoiding a large amount of heat loss of the preheated motor shaft.

[0040] Working principle of the present invention: When in use, the clamping assembly 3 can clamp the motor shaft. Each time the servo motor 406 is started, it drives the driving rod 404 to rotate 90 degrees. The driving rod 404 rotates 90 degrees and drives the rotating column 401 to rotate 90 degrees under the action of two sets of meshing gears 405, thereby driving the working disk 1 to rotate 90 degrees, causing the motor shaft to stay above the preheating assembly 7, between the upper shell 5 and the lower shell 6, and between the upper box 901 and the lower box 902 in sequence. The motor shaft is first preheated, then heat-treated, and then cooled. Finally, the operator removes the processed motor shaft. This device is provided with four sets of clamping assemblies 3. After the device works for a period of time, the motor shaft clamped by one set of clamping assemblies 3 is preheating, the motor shaft clamped by one set of clamping assemblies 3 is heat-treating, the motor shaft clamped by one set of clamping assemblies 3 is cooling, and the operator removes the processed motor shaft at the last set of clamping assemblies 3 and replaces the motor shaft that needs to be heat-treated;

[0041] When the motor shaft moves between the upper shell 5 and the lower shell 6, multiple heating strips 10 in the upper shell 5 and the lower shell 6 work simultaneously to heat the motor shaft, thereby performing heat treatment work. After the heat treatment is completed, the adjustment assembly 4 drives the working disk 1 to rotate 90 degrees, thereby changing the positions of the four sets of clamping assemblies 3 clamping the four sets of motor shafts. The preheated motor shaft moves between the upper shell 5 and the lower shell 6, the heat-treated motor shaft moves between the upper box 901 and the lower box 902, the cooled motor shaft moves to the loading and unloading position (the loading and unloading position is the position that does not contact the three working areas of preheating, heating, and cooling, that is, the position of the clamping assembly 3 farthest from the support frame 402), and the newly loaded motor shaft moves above the preheating assembly 7; and during the rotation of the working disk 1, the upper shell 5 and the lower shell 6 will be in close contact with the working disk 1 for a long time, which can avoid a large amount of heat loss in the upper shell 5 and the lower shell 6, and the heat in the upper shell 5 and the lower shell 6 can quickly heat the next set of motor shafts;

[0042] When the heat-treated motor shaft moves between the upper box 901 and the lower box 902, the water pump 18 is started and the cooling water in the cooling water tank 8 is pumped into the water distribution pipe 903 through the water suction pipe 19 and the water outlet pipe 20. The cooling water in the water distribution pipe 903 sprays out from multiple nozzles 904, and the cooling water sprays on the heat-treated motor shaft to cool the motor shaft. The cooling water after cooling the motor shaft will flow downward into the filter frame 906, and the used cooling water is filtered by the filter frame 906. It should be noted that the receiving frame 905 needs to be disassembled regularly to clean the substances filtered by the filter frame 906. After that, the cooling water in the filter frame 906 will be discharged back into the cooling water tank 8 along the water passing pipe 907;

[0043] During the process of cooling down, when the cooling water flows in the outlet pipe 20, it will drive the second fan blade 22 to rotate. The rotation of the second fan blade 22 will drive the rotation of the rotating shaft 703. The cooling water after cooling the motor shaft will be discharged into the cooling water tank 8 through the through pipe 907. During this process, it will drive the first fan blade 21 to rotate, and the rotation of the first fan blade 21 will also drive the rotation of the rotating shaft 703. It should be noted that the first fan blade 21 and the second fan blade 22 each select fan blades with appropriate arcs to ensure that under the drive of the water flow, the rotation directions of the first fan blade 21 and the second fan blade 22 are the same, thereby ensuring that the rotation directions of the first fan blade 21 and the second fan blade 22 driving the rotating shaft 703 are the same. Furthermore, under the dual action of the rotation of the first fan blade 21 and the second fan blade 22, the rotation of the rotating shaft 703 can be effectively driven.

[0044] At the same time, the cooling water that cools the motor shaft will flow back into the cooling water tank 8, which will cause the temperature of the cooling water in the cooling water tank 8 to rise. At this time, the heat conducting member 11 will conduct the heat in the cooling water. Meanwhile, the semiconductor refrigeration sheet 708 is started. Since the top of the heat conducting member 11 is attached to the heat absorbing end of the semiconductor refrigeration sheet 708, the semiconductor refrigeration sheet 708 will absorb the heat of the heat conducting member 11 and reduce the temperature of the heat conducting member 11, so that the heat conducting member 11 can effectively and continuously conduct the heat in the cooling water, thereby reducing the temperature of the cooling water. Moreover, the heat dissipation end of the semiconductor refrigeration sheet 708 will release heat. At this time, the rotation of the rotating shaft 703 will drive a plurality of first bevel gears 704 to rotate. The rotation of the plurality of first bevel gears 704 will drive a plurality of second bevel gears 705 to rotate. The rotation of the plurality of second bevel gears 705 will drive a plurality of fan shafts 706 to rotate. The rotation of the plurality of fan shafts 706 will drive a plurality of exhaust fan blades 707 to rotate. The exhaust fan blades 707 will accelerate the upward movement of the heat released by the heat dissipation end of the semiconductor refrigeration sheet 708 to avoid heat accumulation. At the same time, the upward movement of the heat will pass through the motor shaft, and the unheated motor shaft can be preheated first. Preheating before the heat treatment of the motor shaft is an important step, which can bring various positive effects and help improve the quality and effect of subsequent heat treatment. And when the working disk 1 rotates and the motor shaft is replaced between the upper shell 5 and the lower shell 6, the second heat insulation plate 26 and the first heat insulation plate 702 will seal the top and bottom of the installation groove 2 where the preheated motor shaft is located to avoid a large amount of heat loss from the preheated motor shaft.

[0045] At the same time, the rotating shaft 703 rotates and under the driving action of the two sets of sprockets 14 and the chain 15, it will drive the stirring rod 12 to rotate. The rotation of the stirring rod 12 will drive the stirring blade 13 to rotate. The rotation of the stirring blade 13 will continuously stir the cooling water, making the temperature of the cooling water in the cooling water tank 8 uniform, so that the water temperature of the cooling water in the cooling water tank 8 can be effectively reduced.

[0046] It should be noted that the heating strip 10, water pump 18, servo motor 406, semiconductor refrigeration chip 708, etc. in the present invention are all prior arts; among them, the working principle of the heating strip involves the coordinated action of multiple components. Mainly, heat is provided through electric heating. The heating strip contains heating wires inside, and heat is generated when an electric current flows through the heating wires. When the heating strip 10 is in use, it needs to be connected to a suitable power supply in cooperation with a dedicated controller; the working principle of the water pump is mainly to use mechanical energy to move liquid (usually water) from one place to another. When the water pump 18 is in use, it needs to be connected to a suitable power supply in cooperation with a dedicated controller; when the semiconductor refrigeration chip is in use, when an electric current passes through the semiconductor refrigeration chip, one side of the refrigeration chip (referred to as the cold side or heat absorption side) will absorb the heat of the surrounding environment, and the temperature of this side will drop, thus achieving a cooling effect. This means that if this cold side is in contact with an object, it will absorb heat from the object and lower its temperature. The other side (referred to as the hot side or heat dissipation side) will release the absorbed heat to the environment, and the temperature of this side will rise. When the semiconductor refrigeration chip 708 is in use, it needs to be connected to a suitable power supply in cooperation with a dedicated controller; a servo motor usually consists of a motor body, an encoder, and a controller. The motor body is used to generate rotational force, and the encoder is used to detect the position of the motor shaft. The controller (servo controller) receives input signals (such as the target angle) and controls the movement of the motor. Moreover, the servo motor adopts a closed-loop control system. The actual rotational position of the motor is monitored in real time through the encoder, and the encoder feeds back the position to the controller, enabling it to compare with the set target angle. If the position of the motor is inconsistent with the required target position (for example, 90 degrees), the controller will automatically adjust the voltage or current to change the rotation of the motor until the precise position is reached. When the servo motor 406 is in use, it needs to be connected to a suitable power supply in cooperation with a dedicated controller, and the servo motor 406 adopts a servo motor with a self-locking structure.

It cannot be determined that the specific implementation of the present invention is only limited to these descriptions. For those of ordinary skill in the technical field to which the present invention pertains, without departing from the concept of the present invention, several simple deductions or substitutions can still be made, which should all be regarded as falling within the protection scope determined by the claims submitted for the present invention.
