The components of the embodiments of the present application usually described and shown in the drawings here can be arranged and designed in various configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application claimed for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present application.
[0029] The following is combined with Figure 1 to Figure 6 The utility model is further described in detail:
[0030] See attached Figure 1 to Figure 6 As shown, a microwave ferrite processing fixture includes a base 1, and the base 1 is provided with two clamping parts, including a first clamping part 22 and a second clamping part 23. The first clamping part 22 and the second clamping part 23 are parallel to each other and are provided at both ends of the base 1, wherein the first clamping part 22 is provided with a cylindrical through hole 20 near the upper top surface, and the second clamping part 23 is provided with a regular hexagonal blind hole 21, and the axes of the cylindrical through hole 20 and the regular hexagonal blind hole 21 are located on the same straight line. It also includes a rotating spindle 3, and the rotating spindle 3 includes a first end 30 with a cylindrical end and a second end 31 with a regular hexagonal shape. The cylindrical shape of the rotating spindle 3 matches the cylindrical through hole 20, and the regular hexagonal shape matches the regular hexagonal blind hole 21. The rotating spindle 3 is provided with a hollow portion 34 which is cylindrical. Three machining surfaces 32 are provided in the axial middle of the rotating spindle 3 . The angle between two adjacent machining surfaces 32 is 60°. Three machining holes 33 are formed at the intersection of the three machining surfaces 32 and the hollow portion 34 .
[0031] When the microwave ferrite 4 needs to be processed on the three side planes 40, the microwave ferrite 4 is first placed in the hollow part 34 of the rotating main shaft 3, and the processing hole 33 will protrude from the part to be processed. The microwave ferrite 4 is fixed by a fixing device. After the microwave ferrite 4 is fixed in the rotating main shaft 3, the rotating main shaft 3 and the microwave ferrite 4 are passed through the first clamping part 22 and the second clamping part 23. Since the second end 31 of the rotating main shaft 3 is in the shape of a regular hexagonal prism, one of the facets of the regular hexagonal prism is horizontal. When the rotating main shaft 3 is installed, one of the processing surfaces 32 is in a horizontal state. At this time, the first side plane 40 of the microwave ferrite 4 is processed by a surface grinder.
[0032] After the first side plane 40 is processed, the rotating spindle 3 is held and pulled out until the second end 31 is separated from the regular hexagonal blind hole 21. Then the rotating spindle 3 is rotated 120 degrees, and after the other edge face of the regular hexagonal prism of the second end 31 that is spaced from the horizontal edge face before the rotation is in a horizontal position, the second end 31 is inserted into the regular hexagonal blind hole 21, and then the second side plane 40 is processed by a surface grinder.

The first end 30 and the third end 35 both extend out of the two clamping parts, so that when the rotating spindle 3 is rotated, the operator can rotate it by holding the first end 30 and the second end 31 with both hands.
[0034] The three machining surfaces 32 are parallel to three mutually spaced edge surfaces of the regular hexagonal prism of the rotating spindle 3. The distance between the machining surface 32 and the outer circumference of the cylindrical hollow portion 34 is 0.18 mm, and the machining accuracy is 0.05 mm.
[0035] The length of the rotating spindle 3 is greater than the distance between the ends of the two clamping parts that are away from each other. The rotating spindle 3 is installed in the cylindrical through hole 20, the regular hexagonal blind hole 21 and the cylindrical through hole of the two clamping parts. The first end 30 extends out of the first clamping part 22, and the third end 35 extends out of the second clamping part 23. The diameter of the cylindrical hollow part 34 of the rotating spindle 3 is 11 mm, and the processing accuracy is 0.02 mm.
[0036] The microwave ferrite 4 to be processed only needs to be clamped once in the hollow part of the rotating shaft, and the three side planes 40 are processed in sequence by rotating the rotating shaft. The regular hexagonal prism of the second clamping part 23 of the base 1 is set to limit the rotating spindle 3 and ensure the accuracy of 120° each rotation of the rotating spindle 3; the consistency of the grinding depth of the side plane 40 is ensured by the parallelism between the center line of the clamping groove at both ends of the base 1 and the bottom surface of the base 1, and finally the high-precision processing of the angle and depth of the three side planes 40 is achieved.
[0037] In summary, the microwave ferrite processing fixture includes a base 1, on which a first clamping portion 22 and a second clamping portion 23 are provided, the first clamping portion 22 and the second clamping portion 23 are parallel to each other and are provided at both ends of the base 1, wherein the first clamping portion 22 is provided with a cylindrical through hole 20 near the upper top surface, and the second clamping portion 23 is provided with a regular hexagonal blind hole 21, and the axes of the cylindrical through hole 20 and the regular hexagonal blind hole 21 are located on the same straight line; it also includes a rotating spindle 3, the rotating spindle 3 includes a first end portion 30 with a cylindrical end and a second end portion 31 with a regular hexagonal prism, the cylindrical shape of the rotating spindle 3 matches the cylindrical through hole 20, and the regular hexagonal shape matches the regular hexagonal blind hole 21; the rotating spindle 3 opens a hollow portion 34, the hollow portion 34 is cylindrical, and three processing surfaces 32 are opened in the axial middle portion of the rotating spindle 3, and the angle between adjacent processing surfaces 32 is 60°.
[0038] Through the second end 31 of the regular hexagonal prism of the rotating main shaft 3, when using a surface grinder for processing, the microwave ferrite 4 cylinder is inserted into the hollow part 34 of the rotating main shaft 3 and clamped and fastened, and the position of the microwave ferrite 4 to be ground will protrude the processing hole 33, and then the grinding process is performed by the grinder. After processing one side plane 40, the rotating shaft is pulled out and rotated 120° to process the second side plane 40, and the rotating shaft is pulled out and rotated 120° to process the third side plane 40. The processing fixture can effectively ensure the processing accuracy of the angle and depth of the three side planes 40 of the workpiece.
[0039] The rotating main shaft 3 is also provided with a fixing device for fixing the microwave ferrite 4, and the fixing device includes a rubber gasket 5 and a plug 6, and the rubber gasket 5 is arranged between the plug 6 and the microwave ferrite 4; the plug 6 is provided with an external thread, and the cylindrical hollow part 34 is provided with an internal thread, and the external thread and the internal thread match each other. The rubber gasket 5 and the plug 6 are fixedly connected by bonding. When it is necessary to grind the microwave ferrite 4, the microwave ferrite 4 is inserted into the hollow part 34 of the rotating main shaft 3, and the plug 6 is rotated into the rotating main shaft 3 based on the external thread and the internal thread of the microwave ferrite 4, and the rubber gasket is squeezed and deformed by rotating the plug 6, so as to achieve the fixing of the microwave ferrite 4, thereby preventing the rotation of the microwave ferrite 4 during the grinding process from affecting the angle accuracy of the processing process in the opposite plane, and finally ensuring the processing angle accuracy.
