[0023] Example 1

[0024] A microwave ferrite ball grinding device, such as Figure 1 As shown, it includes a base 1, a chassis 2 and a bracket 8 arranged above the base 1, an upper cover 3 arranged on the bracket 8 and capable of vertical displacement, and a rotating device for driving the chassis 2 to rotate; the upper cover 3 is arranged just above the chassis 2; Figure 3 As shown, the top surface of the chassis 2 is provided with a grinding groove (wherein Figure 1 The grinding groove is not drawn in the figure). In order to improve the grinding effect, the vertical section of the grinding groove is V-shaped, that is, the grinding groove is a V-shaped groove 6. The bottom end of the upper cover 3 is detachably provided with a polishing cloth 7. Further, as Figure 1 As shown, two brackets 8 are provided, and a slider 9 slidably connected to the two brackets 8 is provided at the top of the upper cover 3, and a weight plate 4 is installed on the slider 9. Further, the chassis 2 is a U-shaped plate, and the rotating device includes a motor 5 arranged at the bottom end of the chassis 2, and a central shaft arranged in the chassis 2, and the central shaft and the output end of the motor 5 are fixedly connected.

[0025] Working principle: Before grinding, clean the grinding tank and the upper cover 3, then brush the polishing cloth 7 clean and stick it on the bottom of the upper cover 3, then put the microwave ferrite balls (particle size is about 0.95mm) to be processed into the grinding tank, then add silicon carbide 1500 mesh abrasive, and place weights on the weight plate 4, so that the slider 9 drives the upper cover 3 to move down. When the upper cover 3 covers the material, turn on the motor 5 switch to drive the chassis 2 to rotate through the central axis, and then through the joint action of the chassis 2 and the upper cover 3 on the material, the microwave ferrite balls (particle size is about 0.95mm) are ground into small balls with a size of 0.82±0.02mm, thereby achieving the purpose of grinding the material on the grinding tank. In addition, because the polishing cloth 7 is set at the bottom of the upper cover 3, the small balls can be polished while grinding.

[0026] When different types of microwave ferrite balls need to be ground, the purpose of adjustable pressure can be achieved by increasing or decreasing the weights on the weight plate 4, thereby facilitating the grinding and polishing of different types of microwave ferrite balls and improving operational flexibility.

[0027] The utility model is an integrated grinding and polishing device, which can grind the microwave ferrite and polish it at the same time, thereby effectively solving the problem of sharpening the surface of the small ball and making the line width △H test result more accurate and reliable.

[0028] Example 2

[0029] In the actual grinding process of Example 1, part of the material will fall along the edge of the bottom plate 2, and it is difficult to effectively collect the part of the material. Figure 2 and Figure 3 As shown, on the basis of Example 1, a material blocking assembly is arranged around the outer wall of the base 1. Further, the material blocking assembly includes a first baffle 11 arranged around the outer wall of the base 1, a second baffle 12 arranged around the outer wall of the first baffle 11, and a third baffle 13 arranged around the outer wall of the second baffle 12, and a material storage cavity 14 is formed between the first baffle 11, the second baffle 12, the third baffle 13 and the base 1; the third baffle 13 is higher than the height of the bottom plate 2; and the first baffle 11 is lower than the height of the bottom plate 2.

[0030] In this solution, when the materials dropped during the grinding operation fall along the edge of the chassis 2, they will directly fall into the storage cavity 14 formed by the first baffle 11, the second baffle 12, the third baffle 13 and the base 1, thereby effectively collecting the dropped materials and avoiding material waste.

[0031] Further, on the basis of Example 2, as Figure 2 and Figure 3 As shown, the side wall of the storage cavity 14 is provided with a discharge port 15, and the second baffle 12 is arranged to be inclined downward along the direction of the discharge port 15. In this solution, by providing the discharge port 15, it is convenient to discharge the materials that fall into the storage cavity 14, thereby improving the convenience of taking materials. By making the second baffle 12 be arranged to be inclined downward along the direction of the discharge port 15, when discharging materials, the materials can automatically slide along the inclined surface to the discharge port 15, thereby effectively improving the discharge efficiency.

[0032] In the description of this patent, it should be understood that the terms "center", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "longitudinal", "horizontal" and the like indicate the orientation or position relationship based on the attached Figure 2The orientation or positional relationship shown is only for the convenience of describing this patent and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as a limitation of this patent.
