Description

Technical Field

[0001] This utility model belongs to the technical field of brazing furnace heating element hanging device, specifically relating to a stable heating element hanging structure for a vacuum brazing furnace. Background Technology

[0002] Vacuum brazing furnaces are core equipment for high-precision brazing processes in aerospace, electronics manufacturing, and other fields. The stable suspension of the heating element directly affects the temperature uniformity within the furnace, the quality of brazed products, and the service life of the equipment. The heating element needs to operate continuously in a high-temperature, vacuum environment above 1000℃, while also meeting core requirements such as insulation, vibration resistance, and adaptability to thermal expansion and contraction. Therefore, the reliability and rationality of the suspension structure are key technical points.

[0003] Currently, the most widely used traditional solution is to connect the heating element to the ceramic insulation component through mounting holes on the heating element body using fastening bolts or threads to achieve insulating fixation inside the furnace liner. However, rigid fixing methods such as bolts and threads limit the thermal deformation space of the heating element, which can easily lead to the heating element being squeezed and cracked during heating-cooling cycles, and the ceramic insulation component being chipped at the edges, significantly shortening the service life of the components. Although the single-end clamping structure has a certain amount of room for movement, the deformation of the heating element cannot be recovered after repeated use, and the cumulative deformation is aggravated. When replacing the heating element, the bolt fixing structure requires disassembling multiple connection points, resulting in low maintenance efficiency. The design of the fixing hole position means that it can only be used with heating elements of specific specifications, resulting in poor flexibility of use.

[0004] Therefore, a stable heating element suspension structure for a vacuum brazing furnace is needed to solve the problems of low installation efficiency and inconvenience in disassembly and assembly of the heating element in the existing technology. Utility Model Content

[0005] The purpose of this invention is to provide a stable heating element suspension structure for a vacuum brazing furnace to solve the problems mentioned in the background art.

[0007] It should be noted in the solution that two mounting holes are provided on the heating body, and the two mounting holes are matched with the hanging rods provided on the heating body.

[0008] It is worth noting that the mounting hole is arranged in an inverted T shape on the heating element body.

[0009] Furthermore, the hanging connection mechanism includes a positioning cylinder, which is inserted into a mounting hole. A baffle is fixedly connected to the bottom end of the positioning cylinder. The positioning cylinder and the baffle are matched and inserted into the heating element body through the mounting hole. A pin is slidably installed inside the positioning cylinder. A first spring is fixedly installed inside the positioning cylinder on one side of the pin. A connecting cylinder is fixedly connected above the positioning cylinder at the bottom end of the hanging rod. An insert rod is fixedly connected inside the connecting cylinder.

[0021] The present invention will be further described below with reference to the embodiments.

[0022] Please see Figure 1-4 This utility model provides a stable heating element suspension structure for a vacuum brazing furnace, including a heating element body 1 and a suspension rod 2. A suspension connection mechanism 3 is provided at the bottom end of the suspension rod 2. An installation hole 101 is provided on the heating element body 1. The heating element body 1 is detachably connected to the bottom end of the suspension rod 2 through the installation hole 101 and the suspension connection mechanism 3. The heating element body 1 is suspended in the vacuum brazing furnace through the suspension rod 2. Two installation holes 101 are provided on the heating element body 1, and the two installation holes 101 are matched with the suspension rod 2 on the heating element body 1. The installation holes 101 are arranged in an inverted T shape on the heating element body 1.

[0023] Further as Figure 2 , Figure 3 and Figure 4 As shown, it is worth noting that the hanging connection mechanism 3 includes a positioning cylinder 301, which is inserted into the mounting hole 101. A baffle 302 is fixedly connected to the bottom end of the positioning cylinder 301. The positioning cylinder 301 and the baffle 302 are inserted into the heating body 1 through the matching mounting hole 101. A pin 303 is slidably installed inside the positioning cylinder 301. A first spring 304 is fixedly installed inside the positioning cylinder 301 on one side of the pin 303. A connecting cylinder 305 is fixedly connected above the positioning cylinder 301 at the bottom end of the hanging rod 2. An insert rod 306 is fixedly connected inside the connecting cylinder 305. A sliding plate 307 is slidably provided on the outside of the insert rod 306. A second spring 308 is fixedly connected to the upper part of 307. The second spring 308 is fixedly connected inside the connecting cylinder 305. A guide rod 309 is fixedly connected to the bottom end of the insertion rod 306. A conical block 3010 is fixedly connected to the outside of the bottom end of the guide rod 309. A conical slider 3011 is slidably arranged on the upper part of the conical block 3010 outside the guide rod 309. Four pins 303 are evenly distributed inside the positioning cylinder 301. One end of the pin 303 is set with an upward slope. The inner diameter of the connecting cylinder 305 matches the outer diameter of the positioning cylinder 301. The conical block 3010 and the conical slider 3011 match each other and are symmetrically arranged on the guide rod 309.

[0024] In use, the positioning cylinder 301, pre-inserted into the mounting hole 101, aligns with the bottom end of the lifting rod 2 for connection. The guide rod 309 is inserted into the bottom end of the positioning cylinder 301. At this time, the conical locking block 3010 presses against the pin 303, causing the pin 303 to slide within the positioning cylinder 301 and press against the first spring 304. This allows the conical locking block 3010 to be inserted into the positioning cylinder 301. When the conical locking block 3010 is at the bottom of the pin 303, the first spring 304... The elastic force causes the pin 303 to push outward, thereby locking the conical block 3010 at the upper part of the pin 3010. At this time, the conical slider 3011 slides on the guide rod 309 above the pin 303. Meanwhile, the top of the positioning cylinder 301 contacts and presses the slide plate 307. Through the elastic force of the second spring 308, the positioning cylinder 301 can be stably locked and limited in the connecting cylinder 305, thus completing the hanging and installation of the heating body 1 on the hanging rod 2.

[0025] When it is necessary to disassemble the heating element body 1, the heating element body 1 is pushed upward, causing the positioning cylinder 301 to press upward against the sliding plate 307. At this time, the pin 303 is pressed inward by the conical slider 3011. When the pin 303 moves upward above the conical slider 3011, under the elastic action of the first spring 304, the pin 303 clamps the conical slider 3011 above it. Then, the heating element body 1 is pulled downward, causing the conical slider 3011 to slide on the guide rod 309, so that the conical slider 3011 and the conical locking block 3010 are in contact. By forming a block, the pin 303 is pressed through the overlapping part of the conical slider 3011 and the conical locking block 3010, thereby disassembling the positioning cylinder 301 at the bottom of the connecting cylinder 305. This completes the disassembly of the heating element body 1, making it easy to replace.

[0026] This solution has the following working process: When this device is in use, the lifting rod 2 is fixedly installed inside the vacuum brazing furnace. At this time, the heating element body 1 needs to be suspended on the lifting rod 2 to facilitate its installation and use inside the vacuum brazing furnace. The positioning cylinder 301, pre-inserted into the mounting hole 101, is then aligned with the bottom end of the lifting rod 2 for connection. The guide rod 309 is inserted into the bottom end of the positioning cylinder 301. The conical locking block 3010 then presses against the pin 303, causing the pin 303 to slide within the positioning cylinder 301. The spring 304 is pressed, causing the conical block 3010 to insert into the positioning cylinder 301. When the conical block 3010 is inserted to the bottom of the pin 303, the spring force of the first spring 304 causes the pin 303 to push outward, thus locking the conical block 3010 at the top. At this time, the conical slider 3011 slides on the guide rod 309 to the top of the pin 303, and the top of the positioning cylinder 301 contacts and presses the slide plate 307. Through the elastic force of the second spring 308, the positioning cylinder 301 can be stably locked and limited within the connecting cylinder 305, thus completing the hanging and installation of the heating body 1 on the lifting rod 2. When it is necessary to disassemble the heating body 1, the positioning cylinder 301 is pushed upwards to press against the sliding plate 307. At this time, the pin 303 is pressed inwards by the conical slider 3011. When the pin 303 moves upwards above the conical slider 3011, the elastic force of the first spring 304 is applied. The pin 303 clamps the conical slider 3011 above it. At this time, the heating body 1 is pulled down, which causes the conical slider 3011 to slide on the guide rod 309, so that the conical slider 3011 and the conical block 3010 are in contact. By forming a block, the pin 303 is squeezed through the overlapping part of the conical slider 3011 and the conical block 3010, thereby disassembling the positioning cylinder 301 at the bottom of the connecting cylinder 305. This completes the disassembly of the heating body 1, making it easy to replace.

[0027] In summary, the hanging connection mechanism 3, which matches and connects to the mounting hole 101 on the heating body 1, allows for convenient and quick connection of the heating body 1 to the hanging rod 2, facilitating the hanging and installation of the heating body 1 in the vacuum brazing furnace. Furthermore, the hanging connection mechanism 3 also allows for easy disassembly of the heating body 1 from the hanging rod 2, enabling replacement of the heating body 1 and improving the efficiency of the device.
