The terms used in this specification are only for describing specific embodiments and are not intended to limit the present invention.

[0044] Reference Figures 1 to 3 The technical solution of the present utility model relates to an iron core heating mechanism, comprising: a mounting frame 100; an outer iron core heating coil 200, which is arranged below the mounting frame 100, and the outer iron core heating coil 200 can accommodate the iron core to be heated; an inner iron core heating coil 300, which is arranged below the mounting frame 100 and is located at the center of the outer iron core heating coil 200; a first power assembly 400, which is arranged on the mounting frame 100, and is used to drive the outer iron core heating coil 200 and the inner iron core heating coil 300 to move up and down; a clamping assembly 500, which is arranged on the mounting frame 100, and the clamping assembly 500 is used to clamp the iron core to be heated; a second power assembly 600, which is arranged on the mounting frame 100, and the second power assembly 600 is used to drive the clamping assembly 500 to move up and down.

[0045] During the heating process, the second power assembly 600 drives the pressing assembly 500 to move downward, and the first power assembly 400 drives the outer iron core heating coil 200 and the inner iron core heating coil 300 to move downward. The pressing assembly 500 first contacts the iron core and presses the iron core. At this time, the second power assembly 600 stops working, and the first power assembly 400 continues to drive the outer iron core heating coil 200 and the inner iron core heating coil 300 to move downward until the outer iron core heating coil 200 covers the outside of the iron core and the inner iron core heating coil 300 is heated. The coil 300 extends into the central axis of the iron core. At this time, the first power component 400 also stops operating. The outer iron core heating coil 200 and the inner iron core heating coil 300 are used to heat the inside and outside of the iron core at the same time. After the heating is completed, the first power component 400 drives the outer iron core heating coil 200 and the inner iron core heating coil 300 to move upward. During the process, the clamping component 500 always maintains a clamping state on the iron core until the second power component 600 drives the clamping component 500 to move upward, and the external robotic arm clamps and transfers the heated iron core.

[0046] The application of the above-mentioned iron core heating mechanism has at least the following beneficial effects: during the heating process of the iron core, the first power component 400 drives the inner iron core heating coil 300 and the outer iron core heating coil 200 to move downward, that is, move toward the position of the iron core, and at the same time the second power component 600 drives the clamping component 500 to move downward. During the process, the clamping component 500 contacts the iron core and presses the iron core, and the inner iron core heating coil 300 and the outer iron core heating coil 200 heat the inside and outside of the iron core at the same time. During the whole process, there is no need to use an external clamp or an additional clamping device to clamp the iron core. While heating, the heating mechanism's own clamping device clamps the iron core. After heating is completed, the iron core can be opened synchronously. The overall structure is compact and simple, and easy to operate. At the same time, it reduces the demand for equipment and reduces production costs.

[0047] According to some embodiments of the present invention, the pressing assembly 500 includes a fixing frame 510, a pressure rod 520 and a pressure block 530. The fixing frame 510 is connected to the bottom of the second power assembly 600. The rod body of the pressure rod 520 is movably connected to the fixing frame 510. The lower end of the pressure rod 520 is connected to the pressure block 530. The fixing frame 510 is provided with a yielding portion 511. The upper end of the pressure rod 520 is movably provided on the yielding portion 511. The rod body of the pressure rod 520 is provided with an elastic member 521. The two ends of the elastic member 521 respectively abut against the pressure block 530 and the fixing frame. The second power assembly 600 drives the fixing frame 510, the pressure rod 520 and the pressure block 530 to move downward until the pressure block 530 abuts the upper end surface of the iron core. Then, the pressure block 530 moves upward under the reaction force of the iron core and drives the pressure rod 520 to move upward. During the process, the elastic member 521 is squeezed between the pressure rod 520 and the fixing frame 510. The elastic member 521 generates elastic potential energy to make the pressure block 530 tend to move downward, thereby better pressing the iron core and also providing a certain buffer to avoid damaging the iron core.

[0048] According to some embodiments of the present invention, the elastic member 521 is configured as a spring or a rubber ring.

[0049] In some other embodiments, the clamping assembly 500 includes a fixed frame 510, a pressure rod 520 and a pressure block 530. The two ends of the pressure rod 520 are respectively connected to the pressure block 530 and the fixed frame 510. The lower end surface of the pressure block 530 is provided with an elastic member 521. In this embodiment, the fixed frame 510, the pressure rod 520 and the pressure block 530 are all rigidly connected, and a certain buffering and elastic clamping effect is achieved by the elastic member 521 under the pressure block 530.

[0050] According to some embodiments of the present invention, the elastic member 521 is configured as a rubber block or a silicone block.

[0051] According to some embodiments of the present invention, the second power assembly 600 includes: a second cylinder 610, which is arranged above the mounting frame 100; a connecting plate 620, which is connected to the output end of the second cylinder 610; two groups of connecting rods 630, which are respectively arranged on both sides of the connecting plate 620, and each group of connecting rods 630 is connected to a clamping assembly 500. The two clamping assemblies 500 are connected by two groups of connecting rods 630, so that the force on the iron core is uniform, the clamping effect is good, and the iron core is prevented from being crushed.

[0052] According to some embodiments of the present invention, the first power assembly 400 includes: a first cylinder 410, which is arranged above the mounting frame 100; a connecting frame 420, which is connected to the output end of the first cylinder 410; a mounting plate 430, which is arranged below the connecting frame 420, and the outer iron core heating coil 200 and the inner iron core heating coil 300 are both connected to the mounting plate 430, and also includes four guide rods 440, the lower ends of the guide rods 440 are connected to the mounting plate 430, and the rods of the guide rods 440 are penetrated by the mounting frame 100, and a guide sleeve 110 is provided at the position of the lower end of the mounting frame 100 corresponding to the guide rods 440.
