Technical Field
[0001] This utility model belongs to the technical field of grinding devices, and more specifically, it relates to an automatic magnetic core grinding device for a flat transformer. Background Technology
[0002] Core grinding is one of the most critical steps in the manufacturing process of planar transformers. By grinding the cores, the two contact surfaces of the cores achieve the highest possible flatness and smoothness, thereby reducing the air gap between the cores, lowering magnetic reluctance, improving the coupling efficiency of the cores, reducing leakage flux, and optimizing transformer performance. However, traditional core grinding is usually done manually. Manual grinding of the cores is inefficient, making it difficult to keep up with the production rhythm of the entire production line, increasing production costs and time. At the same time, the operators have a high workload, needing to continuously rub the cores with two fingers for a long time. Moreover, it is impossible to ensure that the force applied to the cores is consistent during the rubbing process, resulting in inconsistent core grinding effects and affecting the flatness and smoothness of the core contact surfaces.

The following examples are used to illustrate the technical solution of this utility model, but should not be used to limit the scope of protection of this utility model.
[0022] Example:
[0023] like Figures 1 to 4As shown, this utility model provides an automatic magnetic core grinding device for a flat-plate transformer, including a three-axis platform 11 and a holding tray 21.

A magnetic core pressing mechanism is placed above the holding tray 21 and is installed on the X-axis of the three-axis platform 11, moving left and right along the X-axis to efficiently perform the magnetic core grinding operation. The magnetic core pressing mechanism includes an adjustable stroke cylinder 301, and a mounting base 12 is provided on the X-axis of the three-axis platform 11 to provide a reliable mounting point for other components. A mounting plate 13 is detachably installed on one side of the mounting base 12, and the adjustable stroke cylinder 301 is mounted on the mounting plate 13 with screws to ensure that there are no loosening problems during operation, thus guaranteeing the stability of the entire device.
[0024] like Figure 3 , Figure 4 As shown, a hanging rod 302 is provided below the adjustable stroke cylinder 301.

Two sets of linear guide rails 303 are provided on this side of the mounting plate 13. In order to realize the installation of the linear guide rails 303 and the mounting plate 13, the mounting plate 13 has a positioning groove 14 corresponding to the linear guide rails 303. The linear guide rails 303 can be locked in the positioning groove 14. Then, the linear guide rails 303 are connected to the mounting plate 13 by screws, which ensures the stability of the linear guide rails 303 during operation and prevents problems such as loosening or displacement. A slider 304 is slidably provided on the linear guide rails 303. The slider 304 is connected to the hanging rod 302, which allows the hanging rod 302 to slide flexibly on the linear guide rails 303, providing convenience for subsequent adjustment and operation. The adjustable stroke cylinder 301 has a mounting component 305 at its bottom, which further enhances the connection stability between the cylinder and other components. A mounting block 306 is located at the bottom of the mounting component 305. Correspondingly, a mounting groove 307 is formed on the hanging rod 302. The mounting block 306 is engaged within the mounting groove 307, making the connection between the adjustable stroke cylinder 301 and the hanging rod 302 more stable and precise, ensuring effective force transmission.
[0025] The magnetic core pressing mechanism also includes multiple sets of connecting rod fixing seats 308. A hanging rod 302 allows the connecting rod fixing seats 308 to be easily fitted onto the hanging rod 302.

The pressure head mounting seat 311 is connected to one end of the connecting rod 310, thereby realizing the transmission of force from the connecting rod 310 to the pressure head mounting seat 311. Multiple pressure heads 312 are provided at the bottom of the pressure head mounting base 311. The pressure head 312 is a key component that comes into direct contact with the magnetic core. Its outer surface is made of soft rubber material, which can mimic the gentle operation of a human finger on the magnetic core, avoiding damage to the magnetic core. The inner part is made of copper substrate, which ensures the structural strength and stability of the pressure head 312, so that the pressure head 312 can perform well when grinding the magnetic core.
[0026] like Figure 2 As shown, a movable plate 15 is installed on the Y-axis of the three-axis platform 11. The movable plate 15 provides a stable support platform for the installation of subsequent components. Above the movable plate 15 is a positioning base 16. The two are detachably connected, facilitating the replacement of the positioning base 16 during equipment maintenance or according to different production needs.

During installation, the positioning protrusions 18 are locked in the positioning holes 22, improving the installation accuracy of the holding tray 21 on the positioning base 16 and ensuring the positional stability of the holding tray 21 during the grinding operation of the magnetic core, avoiding the impact of tray shaking on the grinding effect. Meanwhile, the positioning base 16 has through slots 19 at both ends, and the holding tray 21 is located above the through slots 19 and can completely cover the through slots 19, so that the operator can easily pick up the holding tray 21.
[0027] The specific usage and function of this embodiment are as follows:
[0028] During use, neatly place the magnetic cores to be ground on the holding tray 21, ensuring the cores are placed stably. Turn on the power to the device and start the adjustable stroke cylinder 301. Adjust the cylinder to generate appropriate pressure through the pressure regulating valve and other related equipment. This pressure is transmitted to the hanging rod 302 through the mounting part 305 and the mounting block 306. According to production needs, use the sliding function of the slider 304 on the linear guide rail 303 via the hanging rod 302, and the cooperation of the connecting rod 310 and the connecting rod fixing seat 308 to adjust the position of the pressure head 312 so that it is accurately aligned with the magnetic cores on the holding tray 21. Control the three-axis platform 11 to move the holding tray 21 in the Y-axis direction and the magnetic core pressing mechanism in the X-axis direction, and perform the grinding operation on the magnetic cores through the pressure head 312. During the grinding process, the cylinder pressure and the position of the pressure head 312 can be finely adjusted according to the actual situation to ensure good grinding effect.
