Description

Technical Field

[0001] The utility model relates to the technical field of vacuum high-temperature furnaces, in particular to an ultra-high vacuum high-temperature furnace. Background Art

[0002] The application of ultra-high vacuum high-temperature furnaces in the field of electrical equipment is mainly reflected in the vacuum heating treatment of materials. The main purpose of this treatment method is to obtain materials with superior performance through processes such as degassing, degreasing and surface purification.

[0003] Existing technologies typically place the material being processed directly into a high-temperature furnace. However, since the material cannot be rotated or flipped during the entire process, it is prone to uneven heating. This not only affects the quality and stability of the final product, but can also lead to localized overheating and even damage. Utility Model Content

[0004] The purpose of the utility model is to solve the problem in the prior art that materials are easily heated unevenly, which not only affects the quality stability of the final product, but may also cause local overheating or even damage. An ultra-high vacuum high-temperature furnace is proposed.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] An ultra-high vacuum high-temperature furnace comprises a high-temperature furnace body, wherein a pair of rotating rods are rotatably connected to the inner side wall of the high-temperature furnace body, a first rotating seat and a second rotating seat are fixedly connected to the opposite side walls of the two rotating rods, a servo motor for driving the rotating rods to rotate is fixed to the high-temperature furnace body, and a pair of limit plates are provided on the first rotating seat and the second rotating seat;

[0007] The first rotating seat and the second rotating seat are provided with a driving structure for driving the two limiting plates to move synchronously.

[0008] Preferably, the driving structure includes a bidirectional screw rotatably connected to the second turntable, the top end of the bidirectional screw extends above the second turntable and is fixedly connected to a screw block, a sliding rod is fixedly connected to the first turntable, and a pair of mounting blocks are provided on the bidirectional screw and the sliding rod, and the mounting blocks are fixed relative to the limit plate.

[0009] Preferably, one pair of the mounting blocks is threadedly connected to the bidirectional lead screw, and the other pair of the mounting blocks is vertically slidably connected to the slide rod.

[0010] Preferably, a protrusion is fixedly connected to the bottom end of the second rotating seat, the bottom end of the bidirectional screw extends to below the second rotating seat, a top screw is threadedly connected to the protrusion, and one end of the top screw is against the bidirectional screw.

[0011] Preferably, sliding grooves are provided on opposite side walls of the first rotating seat and the second rotating seat, and the mounting block is vertically slidably connected to the sliding grooves.

[0012] Preferably, a plurality of through holes are formed on the limiting plate, and the limiting plate and the mounting block are threadedly connected with the same fastening bolt.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] The utility model places the material to be processed on the top of the lower limit plate through the setting of the driving structure. The staff uses tools or manually screws the screw block to make the two-way screw drive the two limit plates to move relative to each other and clamp the material. Then, when the heating treatment is carried out, the motor is started to drive the limit plates and the material clamped therein to rotate synchronously, ensuring that multiple parts of the material can be evenly affected by heat during the heating process, effectively avoiding the problems of local overheating or uneven heating that are common in traditional static heating methods.

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] Reference Figure 1-Figure 3The ultra-high vacuum high-temperature furnace includes a furnace body 1. The furnace body 1 provides an ultra-high vacuum environment. This high vacuum helps reduce impurity interference, improve material purity, and improve product quality. A pair of rotating rods 2 are rotatably connected to the inner sidewalls of the furnace body 1. Rotation of the rotating rods 2 rotates the material being processed. A first rotating seat 3 and a second rotating seat 4 are fixedly connected to opposing sidewalls of the rotating rods 2. Both the first and second rotating seats 3 and 4 are concave in shape to facilitate the installation of subsequent components.

[0021] A servo motor 5 is fixed to the high-temperature furnace body 1, driving the rotating rods 2. This servo motor 5 drives one of the rotating rods 2, which in turn rotates the other rotating rod 2, which is rotatably connected to the inner wall of the high-temperature furnace body 1 via a bearing. A pair of limit plates 6 are installed on the first and second rotating bases 3 and 4. These limit plates 6 clamp and secure the material being processed, preventing it from shifting and being affected by the heat.

[0022] The first rotating seat 3 and the second rotating seat 4 are provided with a driving structure for driving the two limiting plates 6 to move synchronously.

[0023] The driving structure includes a bidirectional screw 7 rotatably connected to the second rotating seat 4. The top end of the bidirectional screw 7 extends to the top of the second rotating seat 4 and is fixedly connected to a screw block 8. The setting of the screw block 8 is ergonomic, which is not only convenient for the staff to manually screw. Its hexagonal setting also makes it convenient for the staff to use tools for screwing operations.

[0024] A slide rod 12 is fixedly connected to the first rotating seat 3, and a pair of mounting blocks 9 are provided on both the bidirectional lead screw 7 and the slide rod 12, and the mounting blocks 9 are fixed relative to the limit plate 6. The setting of the slide rod 12 makes the force on the limit plate 6 more balanced when it moves vertically, so that the movement is more stable.

[0025] Wherein a pair of mounting blocks 9 is threadedly connected with the bidirectional lead screw 7, and another pair of mounting blocks 9 is vertically slidably connected with a slide bar 12. The rotation of the bidirectional lead screw 7 drives the two mounting blocks 9 thereon to move relative to or away from each other.

[0026] A protrusion 10 is fixedly connected to the bottom end of the second rotating seat 4. The bottom end of the bidirectional screw 7 extends below the second rotating seat 4. A jackscrew 11 is threadedly connected to the protrusion 10. One end of the jackscrew 11 abuts against the bidirectional screw 7. The jackscrew 11 is used to fix the bidirectional screw 7 to prevent it from rotating and affecting the clamping and fixing effect of the two limit plates 6.

[0027] Slide grooves 14 are provided on the opposite side walls of the first rotating base 3 and the second rotating base 4. The mounting block 9 is vertically slidably connected to the slide grooves 14. The provision of the slide grooves 14 not only enhances the aesthetics but also further ensures the stability of the movement of the mounting block 9 after installation. The slide grooves 14 provide a preset trajectory for the movement of the mounting block 9.

[0028] The stopper plate 6 is provided with multiple through-holes to facilitate heat transmission. The stopper plate 6 and the mounting block 9 are threadedly connected by a common fastening bolt 13. This arrangement allows the stopper plate 6 to be selected to suit the size and shape of the material being used, achieving a better clamping and securing effect.

[0029] The functional principle of this utility model can be explained through the following operation modes:

[0030] Select a suitable limit plate 6 according to the size and shape of the material to be processed and install it between the first rotating seat 3 and the second rotating seat 4. Use the same fastening bolt 13 to fix the limit plate 6 on the mounting block 9 to ensure its accurate and stable position.

[0031] Open the door of the high-temperature furnace body 1 and place the sample to be heated or processed between the limit plates 6. Tighten the screw block 8 on the bidirectional screw 7 to gradually bring the two limit plates 6 closer together until they are completely clamped. However, be careful not to apply excessive force to avoid damaging the sample. Then, tighten the top screw 11 to maintain appropriate pressure to prevent the bidirectional screw 7 from rotating on its own and causing a decrease in clamping force.

[0032] After closing the door of the high-temperature furnace body 1, set the required temperature, time and other relevant parameters through the control panel. After confirming that all settings are correct, turn on the servo motor 5 to drive the rotating rod 2 to start rotating, thereby driving the limit plate 6 and the material clamped by the two limit plates 6 to rotate.

[0033] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
