[0020] In order to facilitate understanding of the utility model, the utility model will be more fully described below with reference to the relevant drawings.

[0021] Please refer to Figure 1 , Figure 2 , Figure 3As shown in the figure, a magnetic core baking fixing clamp 10 comprises a bottom plate 100, a top plate 200, a positioning side plate 300 and an elastic shaping assembly 400. The bottom plate 100 and the top plate 200 are oppositely arranged, and the positioning side plate 300 is located between the bottom plate 100 and the top plate 200. A positioning groove 310 is formed on the positioning side plate 300. The elastic shaping assembly 400 is arranged on the top plate 200 and located in the positioning groove 310. The elastic shaping assembly 400 comprises a positioning pressing plate 410. When the magnetic core 20 is placed in the positioning groove 310, the positioning pressing plate 410 abuts against the magnetic core 20, so that the magnetic core 20 is clamped and positioned between the bottom plate 100 and the elastic shaping assembly 400.

[0022] It should be noted that the magnetic core 20 which is completed by dispensing assembly is first placed in the positioning groove 310. Through the positioning groove 310, the bottom plate 100 and the top plate 200, the magnetic core 20 is initially positioned. Then the elastic shaping assembly 400 is used to press and shape the magnetic core 20. Specifically, the positioning pressing plate 410 is used to press the magnetic core 20, and the pressing surface of the positioning pressing plate 410 and the bonding area 23 of the magnetic core 20 are on the same axis, so that the magnetic core 20 is located between the bottom plate 100 and the positioning pressing plate 410 of the elastic shaping assembly 400, thereby realizing the positioning and fixing of the magnetic core 20. In this way, the misalignment of each magnet of the magnetic core 20 can be avoided, and the deformation or skew of the baked magnetic core 20 can be avoided.

[0023] Please refer to Figure 1 In an embodiment, the elastic shaping assembly 400 further comprises a shaping screw 420 and a buffer spring 430. One end of the shaping screw 420 is connected with the top plate 200, and the other end of the shaping screw 420 is connected with the positioning pressing plate 410. The buffer spring 430 is sleeved on the shaping screw 420 and located between the positioning pressing plate 410 and the top plate 200. A screw hole matched with the shaping screw 420 is formed on the top plate 200. The shaping screw 420 passes through the screw hole on the top plate 200, extends into the positioning groove 310 and is connected with the positioning pressing plate 410, so as to realize the installation of the positioning pressing plate 410. When the positioning pressing plate 410 abuts against the magnetic core 20, the buffer spring 430 is compressed, so that the buffer spring 430 is compressed. In this way, the buffer spring 430 can be used to buffer and press the magnetic core 20, so as to avoid the damage of the magnetic core 20 caused by over-pressing.

[0024] Please refer to Figure 3 In an embodiment, a positioning magnet 320 is arranged on the side of the positioning side plate 300 away from the positioning groove 310, and the position of the positioning magnet 320 corresponds to the position of the positioning groove 310.

[0025] It should be noted that the magnetic core baking fixing clamp 10 is used in different ways, and can be selected to be placed vertically or horizontally according to the baking equipment; the vertical placement is that the positioning side plate 300 is parallel to the floor, at this time, the magnetic core 20 can be tightly abutted with the bottom surface of the positioning groove 310 by the gravity of the magnetic core 20 itself, so as to avoid the misalignment of the magnet on the magnetic core 20; the horizontal placement is that the positioning side plate 300 is perpendicular to the floor, at this time, the magnetic core 20 cannot be tightly abutted with the bottom surface of the positioning groove 310, so that the magnet is misaligned, therefore, in the embodiment, the positioning magnet 320 is arranged on the side of the positioning side plate 300 away from the positioning groove 310, the magnetic core 20 in the positioning groove 310 is fixed by the positioning magnet 320, so that the magnetic core 20 can be abutted with the bottom surface of the positioning groove 310, thus, the problem of deformation and skew of the baked magnetic core 20 can be avoided.
