Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of stator rotor heating, specifically to a new energy automobile stator rotor medium frequency coil heating device. BACKGROUND

[0002] When the magnetic flux enclosed by the conductor loop changes, an induced potential will be generated in the loop. Similarly, a conductor in an alternating magnetic field will also generate an induced potential due to electromagnetic induction, forming an induced current (eddy current) in the conductor. The induced current overcomes the electrical resistance of the conductor itself to generate Joule heat, which heats the conductor itself, causing it to warm up and melt, achieving various thermal processing purposes. This is the principle of medium frequency induction heating.

[0003] In the field of new energy vehicles, when alternating current passes through the medium frequency coil, an alternating magnetic field is generated around the coil. Placing the stator and rotor of a new energy vehicle in this alternating magnetic field will generate an induced electromotive force inside the stator and rotor. Since the stator and rotor are usually made of conductive materials, the induced electromotive force will form an induced current, also known as eddy current, inside them. According to Joule's law, these eddy currents will generate heat when flowing inside the stator and rotor due to the electrical resistance of the materials, thereby achieving the heating of the stator and rotor.

[0004] However, after the stator and rotor are heated, they need to be cooled to ensure the stability of the material properties. However, the temperature of the heated stator and rotor is relatively high, and if the operator directly takes the stator and rotor, the operator's body parts may come into contact with the stator and rotor, causing serious burns.

When the stator rotor is placed on the bearing table 4, the operator installs the bearing table 4 with the stator rotor and the mounting frame 3 in the mounting seat 21, controls the rotating disc 2 to rotate by using the driving assembly inside the base 1, and then can drive the mounting seat 21 to control the stator rotor to rotate to the lower side of the heating coil 12;

[0026] When the stator rotor is located below the heating coil 12, the heating coil 12 is controlled to descend along the sliding frame 11, so that the stator rotor is in the heating coil 12, and the heating device is started. The heating coil 12 generates an alternating magnetic field through a medium-frequency current. In this alternating magnetic field, the stator rotor generates an induced electromotive force inside due to the principle of electromagnetic induction, and then forms an eddy current. According to Joule's law, the eddy current generates heat inside the stator rotor, thereby realizing heating of the stator rotor;

[0027] After heating, the heating coil 12 is controlled to rise, and the heated stator rotor is rotated to the position area where the operator takes by the rotating disc 2. The operator holds the handle 5 to drive the mounting frame 3 to rise in the mounting seat 21, so that the bearing table 4 rises with the stator rotor, and leaves the mounting seat 21. Without directly contacting the high-temperature stator rotor, scalding is avoided.

[0028] Embodiment 2:

[0029] In order to ensure the stability of the mounting frame 3 and the bearing table 4 when the rotating disc 2 rotates, please refer to Figures 1-4 On the basis of embodiment 1, the inside of the handle 5 is provided with a connecting frame 51, the connecting frame 51 is connected with the inner wall of the handle 5 through a spring 52, a button 53 is fixedly installed on the connecting frame 51, and the button 53 penetrates through the side wall of the handle 5;

[0030] Both ends of the connecting frame 51 are provided with connecting grooves 511, a moving block 54 is installed in the connecting grooves 511, and grooves 541 are formed in the top and bottom of the moving block 54. The grooves 541 are inclined, one end of the connecting groove 511 is slidably arranged in the groove 541, and the moving block 54 is connected with the inner wall of the handle 5 through a spring 55;

[0031] The mounting frame 3 is matched with the mounting groove 22, a moving groove 31 is formed in the inside of the mounting frame 3, a moving plate 32 is slidably installed in the inside of the moving groove 31, one side of the moving plate 32 is connected with the inner wall of the moving groove 31 through a spring 322, the other side of the moving plate 32 is fixedly connected with a limiting block 35, the limiting block 35 is matched with the mounting groove 22 in correspondence, and one end of the limiting block 35 is provided in an inclined manner;

[0032] The top two ends of the moving groove 31 are communicated with the sliding groove 34, and the two ends of the moving plate 32 are fixedly installed with the push plate 321 which is arranged in the sliding groove 34.

The button 53 is fixed on the connecting frame 51, and pressing the button 53 will make the connecting frame 51 move to the inside of the handle 5 against the elastic force of the spring one 52. Since the connecting groove 511 at both ends of the connecting frame 51 is connected with the moving block 54, and one end of the connecting groove 511 slides in the inclined slot 541 at the top and bottom of the moving block 54, the movement of the connecting frame 51 will make the moving block 54 move to the inner wall direction of the handle 5 under the action of the slot 541, compress the spring two 55, and make the connecting block 542 move out of the limiting hole 33, so as to facilitate the operator to control the handle 5 to move along the sliding groove 34, in this process, the handle 5 pushes the push plate 321 to move, and then affects the moving plate 32 in the mounting frame 3, so that the moving plate 32 slides in the moving groove 31 against the elastic force of the spring three 322, and the limiting block 35 on the other side of the moving plate 32 will be retracted into the moving groove 31, so as to release the locking state between the mounting frame 3 and the mounting groove 22 of the mounting seat 21, and facilitate the operator to take out the mounting frame 3 from the mounting seat 21, so as to take out the bearing table 4 and the stator and rotor placed thereon together.

Because the mounting frame 3 is matched with the mounting groove 22 of the mounting seat 21, when put in, the moving plate 32 in the moving groove 31 of the mounting frame 3 is extruded at the edge of the mounting groove 22, so that the spring three 322 is in the compressed state, when the limiting block 35 corresponds to the limiting groove 23, the spring three 322 acts to make the limiting block 35 pop out and be clamped with the mounting groove 22, so the fixing is completed. The rotating disc 2 is rotated by the driving assembly of the base 1, the mounting seat 21 and the stator and rotor are driven to rotate to the position below the heating coil 12, then the heating coil 12 is controlled to descend along the sliding frame 11, so that the stator and rotor are in the heating coil 12, the heating device is started, the heating coil 12 passes the intermediate frequency current to generate an alternating magnetic field, the stator and rotor generate induced electromotive force and eddy current in the magnetic field due to electromagnetic induction, and heat is generated according to Joule's law to achieve heating.

[0036] After heating is completed, first make the heating coil 12 ascend, the heated stator and rotor are rotated to the position for being taken by the operator by the rotating disc 2, the operator holds the handle 5 and presses the side wall button 53 of the handle 5, the button 53 drives the connecting frame 51 to move to the inside of the handle 5 against the elastic force of the spring one 52, the connecting frame 51 is matched with the slot 541 of the moving block 54 through the connecting groove 511, so that the moving block 54 compresses the spring two 55 and makes the connecting block 542 move out of the limiting hole 33, at the same time, the handle 5 pushes the push plate 321, drives the moving plate 32 to make the limiting block 35 retract into the moving groove 31 against the elastic force of the spring three 322, so the locking of the mounting frame 3 and the mounting seat 21 is released, and then the mounting frame 3 and the bearing table 4 and the stator and rotor can be taken out, the handle 5 is controlled to move along the sliding groove 34, so that the connecting block 542 is repositioned into the limiting hole 33 under the action of the spring two 55, thereby the stability of the handle 5 is ensured, and the operator can control conveniently.
