Description

Technical Field

[0001] This utility model relates to the field of ferrite cores, and in particular to a rotary ferrite core press for use in high-power microwave devices. Background Technology

[0002] A magnetic core is a sintered magnetic metal oxide composed of various iron oxide mixtures. It is mainly composed of three metal elements: iron (Fe), manganese (Mn), and zinc (Zn), and is commonly known as manganese-zinc ferrite. Since toroidal ferrite cores have no air gap, rotary presses are currently used in the ferrite core forming process. Rotary presses are miniaturized versions of tablet presses that are used for automatic rotation and continuous tablet pressing.

[0003] Chinese Patent Publication No. CN220821294U discloses a rotary ferrite core press, which stabilizes the rotating column by rolling positioning balls in a positioning guide rail, resulting in good stability of the rotating column during long-term use. In practical applications, the assembly of the rotating cylinder in the above-mentioned device is quite cumbersome and extremely labor-intensive, but the movable rotating cylinder will affect the stability of use. Therefore, we propose a rotary ferrite core press for high-power microwave devices. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, the purpose of this utility model is to provide a rotary ferrite core press for high-power microwave devices. By setting an auxiliary mechanism, the movable rotating cylinder can maintain good stability after installation and use. Moreover, the auxiliary mechanism and the rotating cylinder are movably connected, so the structure of the two allows the rotating cylinder to be quickly assembled, which greatly saves the efficiency when replacing the rotating cylinder.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A rotary ferrite core press for high-power microwave devices includes a main body, auxiliary mechanisms installed on the left and right sides of the upper end of the main body, and a connecting mechanism installed in the middle of the upper end of the main body.

[0007] The auxiliary mechanism includes a drive box, an electric push rod fixedly installed at the inner end of the drive box, a reinforcing frame fixedly installed at the middle of the lower end of the electric push rod, an installation block fixedly installed at the inner end of the electric push rod, a pressing groove fixedly provided inside the installation block, a pressing block movably installed inside the pressing groove, a ball fixedly installed on the inner side of the upper end of the pressing block, and a retaining spring fixedly installed at the lower end of the pressing block. The retaining spring allows the pressing block to move up and down inside the pressing groove, facilitating connection with external structures.

[0008] Furthermore, the main structure includes an operating table, a support frame fixedly installed on the lower side of the operating table, a base fixedly installed on the lower end of the support frame, a rotary motor fixedly installed in the middle of the upper end of the base, a transmission rod fixedly installed on the upper end of the rotary motor, a connector fixedly installed on the upper end of the transmission rod, a connecting groove fixedly provided inside the upper end of the connector, and a ball bearing fixedly installed in the middle of the upper end of the operating table. By setting the support frame in the middle of the operating table and the base, space is left between the two to provide a mounting position for the rotary motor, and the mounting position of the rotary motor in the middle of the base also provides a certain degree of protection.

[0009] Furthermore, the connecting mechanism includes a rotating cylinder, a slot is fixedly provided inside the outer end of the rotating cylinder, sliding grooves are fixedly provided at the upper and lower ends of the slot, and a connecting block is fixedly provided at the lower end of the rotating cylinder. By providing the sliding groove, the ball bearing installed at the upper end of the pressing block can move smoothly inside the slot.

[0010] Furthermore, the drive box is fixedly installed on the left and right sides of the upper end of the operating table, and the pressing block is movably installed inside the pressing groove through a retaining spring. When force is applied to the pressing block during operation, the pressing block can drive the inner end to move downward through the elastic compression of the retaining spring. When the end of the inner end of the symmetrically installed pressing block is compressed to less than the height of the retaining groove, the pressing block and the rotating cylinder can be connected. Repeating the operation once can separate the rotating cylinder and the pressing block. The design of this structure provides a limit structure for the rotating cylinder movably installed on the upper end of the operating table and maintains good stability during rotation.

[0011] Furthermore, the pressing block has a U-shaped structure, and the pressing groove has a T-shaped structure.

[0012] Furthermore, the connector and the operating table are movably connected, and the ball bearings are arranged in a ring at the center of the upper part of the operating table.

[0013] Furthermore, the rotating cylinder is movably connected by a connecting block and a connecting head, the slot is an annular structure, and the sliding grooves are symmetrically distributed at the upper and lower ends of the slot.

[0014] Furthermore, the groove and the ball are adapted to each other, and the inner end of the mounting block has an arc-shaped structure.

[0015] In summary, this utility model has the following beneficial effects:

[0016] 1. The pressing block can move its inner end downwards by the elastic compression of the snap ring. When the inner end of the symmetrically installed pressing block is compressed to a height less than that of the slot, the pressing block and the rotating cylinder can be connected. This structure adds an auxiliary structure to the movable connection between the rotating cylinder and the connector. By repeating the operation once, the rotating cylinder and the pressing block can be separated, making the rotating cylinder easy to install and remove and easy to assemble.

[0017] 2. By setting a sliding ball, the lower end of the rotating cylinder contacts the sliding ball during rotation, reducing the friction between the rotating cylinder and the operating table. The rotation of the sliding ball can also make the rotating cylinder accelerate faster, thus making the rotation of the rotating cylinder smoother and more stable. Attached Figure Description

[0026] Reference Figure 1-5 As shown, a rotary ferrite core press for high-power microwave devices is provided in a preferred embodiment of the present invention. It includes a main body 1, auxiliary mechanisms 2 are installed on the left and right sides of the upper end of the main body 1, and a connecting mechanism 3 is installed in the middle of the upper end of the main body 1.

[0027] The auxiliary mechanism 2 includes a drive box 201. An electric push rod 202 is fixedly installed at the inner end of the drive box 201. A reinforcing frame 203 is fixedly installed at the middle of the lower end of the electric push rod 202. An installation block 204 is fixedly installed at the inner end of the electric push rod 202. A pressing groove 205 is fixedly provided inside the installation block 204. A pressing block 206 is movably installed inside the pressing groove 205. A ball bearing 207 is fixedly installed on the inner side of the upper end of the pressing block 206. A retaining spring 208 is fixedly installed at the lower end of the pressing block 206. The retaining spring 208 allows the pressing block 206 to move up and down inside the pressing groove 205, facilitating connection with external structures.

[0028] The main structure 1 includes an operating table 101. A support frame 102 is fixedly installed on the lower side of the operating table 101. A base 103 is fixedly installed on the lower end of the support frame 102. A rotary motor 104 is fixedly installed in the middle of the upper end of the base 103. A transmission rod 105 is fixedly installed on the upper end of the rotary motor 104. A connector 106 is fixedly installed on the upper end of the transmission rod 105. A connecting groove 107 is fixedly provided inside the upper end of the connector 106. A ball bearing 108 is fixedly installed in the middle of the upper end of the operating table 101. By setting the support frame 102 in the middle of the operating table 101 and the base 103, space is left between the two to provide a mounting position for the rotary motor 104. The mounting position of the rotary motor 104 in the middle of the base 103 also provides a certain degree of protection.

[0029] The connecting mechanism 3 includes a rotating cylinder 301. A slot 302 is fixedly provided inside the outer end of the rotating cylinder 301. Slide grooves 303 are fixedly provided at the upper and lower ends of the slot 302. A connecting block 304 is fixedly provided at the lower end of the rotating cylinder 301. By providing the slide groove 303, the ball bearing 207 installed on the upper end of the pressing block 206 can move smoothly inside the slot 302.

[0030] The drive box 201 is fixedly installed on the left and right sides of the upper end of the operating table 101. The pressing block 206 is movably installed inside the pressing groove 205 through the snap ring 208. When force is applied to the pressing block 206 during operation, the pressing block 206 can drive the inner end to move downward through the elastic compression of the snap ring 208. When the end of the inner end of the symmetrically installed pressing block 206 is compressed to a height less than that of the groove 302, the pressing block 206 and the rotating cylinder 301 can be connected. Repeating the operation once can separate the rotating cylinder 301 and the pressing block 206. The design of this structure provides a limit structure for the rotating cylinder 301 movably installed on the upper end of the operating table 101 and maintains good stability during rotation.

[0031] The pressing block 206 has a U-shaped structure, and the pressing groove 205 has a T-shaped structure. By setting the pressing groove 205 to a T-shaped structure, the stacked pressing block 206 can move up and down in the pressing groove 205.

[0032] The connector 106 and the operating table 101 are movably connected. The sliding ball 108 is distributed in a ring at the middle of the upper end of the operating table 101. By setting the sliding ball 108, the friction between the rotating cylinder 301 and the operating table 101 during rotation is reduced, making the rotating cylinder 301 rotate more smoothly.

[0033] The rotating cylinder 301 is movably connected to the connector 106 via the connecting block 304. The slot 302 has an annular structure, and the sliding grooves 303 are symmetrically distributed at the upper and lower ends of the slot 302.

[0034] The slide 303 and the ball 207 are compatible. The inner end of the mounting block 204 is an arc-shaped structure. The mounting block 204 is set as an arc-shaped structure and fits with the outer end of the rotating cylinder 301 to reduce the resistance of the mounting block 204 when the rotating cylinder 301 rotates.

[0035] Specific implementation process: During operation, first, insert the connecting block 304 at the lower end of the rotating cylinder 301 into the connecting groove 107 at the inner end of the connecting head 106 at the upper end of the operating table 101. After placement, the drive box 201 pushes the electric push rod 202 to move the mounting block 204 closer to the outer end of the rotating cylinder 301. During this process, manual force is applied to the pressing block 206. The pressing block 206, through the elastic compression of the retaining spring 208, can move its inner end downward. When the inner end of the symmetrically installed pressing blocks 206 is compressed to a height less than the groove 302, the pressing block 206 and the rotating cylinder 301 can be connected. This structure connects the rotating cylinder 301 and... An auxiliary structure has been added to the movable connection of the connector 106, which can drive the rotating cylinder 301 to rotate. During the rotation of the rotating cylinder 301, the lower end of the rotating cylinder 301 contacts the sliding ball 108, reducing the friction between the rotating cylinder 301 and the operating table 101 during rotation, making the rotation of the rotating cylinder 301 smoother. At the same time, the pressing block 206 also provides a limit structure for the rotating cylinder 301, which is movably mounted on the upper end of the operating table 101, and maintains good stability during rotation. By repeating the operation once, the rotating cylinder 301 and the pressing block 206 can be separated. This structure makes the rotating cylinder 301 easy to install and remove, and facilitates assembly.
