[0003] Authorization announcement number CN214701694U discloses a novel double-layer vacuum heating furnace. This device mainly ensures the vacuum during heating by setting up a separate heating box inside the vacuum pressure chamber and locking the sealing door with a locking ring. A heat insulation block is installed between the lower part of the heating box and the support legs to effectively reduce heat transfer, thereby improving the overall quality and heating efficiency of the heating element and enhancing overall performance. However, the device still has the following drawbacks in actual use:
[0004] The aforementioned patent mainly ensures a vacuum environment during heating by locking the sealing door. However, in actual operation of the vacuum heating furnace, the connection between the outer shell and the sealing door is difficult to calibrate and position, which can easily lead to positional deviations during installation of the sealing door, affecting its sealing performance. Furthermore, the heating furnace is usually set in a fixed position, making it difficult to adjust the position of the furnace for heating double-layer heating parts or materials, increasing the difficulty and inconvenience of loading and unloading.

[0026] There are four sets of reinforcing blocks 7, and the four sets of reinforcing blocks 7 are connected by a support frame 8, which improves the reinforcement strength of the internal structure of the outer shell 1 and prevents the shell from deforming.
[0027] The inner sides of the two reinforcing blocks 7 are provided with guide grooves, and the inner sides of the guide grooves are provided with guide blocks. The guide blocks are connected to the heating box 5 to increase the horizontal limiting effect of the movement of the heating box 5.
[0028] The horizontal displacement mechanism 6 includes a servo motor 61. The servo motor 61 is located at one end of the back of the outer shell 1. The servo motor 61 is model SGM7A. The output end of the servo motor 61 is provided with a threaded post 62 extending into the interior of the outer shell 1. The outer side of the threaded post 62 is provided with a threaded displacement platform 63. The heating box 5 is set on the displacement platform 63.
[0029] The sealing mechanism 2 includes a sealing door plate 21. One end of the servo motor 61 is connected to the sealing door plate 21. One end of the back of the sealing door plate 21 is provided with calibration blocks 22 in the same number as the reinforcing blocks 7. One end of each set of reinforcing blocks 7 is provided with a calibration groove 24 that matches the calibration block 22. The two calibration blocks 22 are provided with card holes 23 on both sides.
[0030] The positioning mechanism 4 includes an adjusting motor 41, which is located at the top of the mounting groove 3. The output end of the adjusting motor 41 is provided with a rotating rod 42. A first bevel gear 43 is provided on the outer side of the rotating rod 42. Threaded rods 45 are sleeved on both sides inside the mounting groove 3. A second bevel gear 44 is provided on the side of the two threaded rods 45 that is close to each other, and the second bevel gear 44 meshes with the first bevel gear 43. An internal threaded tube 46 is provided on the outer side of the two threaded rods 45, and a connecting arm 47 is provided on one side of the internal threaded tube 46. Limiting grooves are provided on both sides of the top inside the mounting groove 3, and a limiting block connected to the internal threaded tube 46 is provided on the inner side of the limiting groove, which increases the limiting and guiding effect of the horizontal movement of the internal threaded tube 46, so as to drive the displacement adjustment of the connecting arm 47.
[0031] The outer side of the rotating rod 42 is provided with a positioning tube 48, and the positioning tube 48 is opposite to the vertical plane of the heating box 5. The bottom of the two connecting arms 47 on one side is provided with a locking rod 49, and the locking rod 49 is properly matched with the locking hole 23.
[0032] Example 1, such as Figure 1-5 As shown, both the outer shell 1 and the sealing door panel 21 are octagonal structures. The inner side of the sealing door panel 21 is provided with a sealing gasket, and the sealing gasket is sealed and adapted to the port of the outer shell 1. Through the structural splicing of the octagonal outer shell 1 and the sealing door panel 21, the sealing door panel 21 can easily drive the four sets of calibration blocks 22 and calibration slots 24 for calibration and positioning, thereby increasing the stability and sealing strength of the structural splicing.

The positioning tube 48 is opposite to and in contact with the vertical surface of the positioning recess 51. When the heating box 5 is positioned in a designated position inside the outer shell 1 by adjusting the structure of the horizontal displacement mechanism 6, the positioning recess 51 on the top of the heating box 5 is opposite to the vertical surface of the positioning tube 48, so that the positioning tube 48 can contact the positioning recess 51 by descending, thereby fixing the heating box 5 as a whole and preventing position movement.
[0034] Working principle: This deformation-resistant and reinforced double-layer sealed heating furnace shell;
[0035] When the device is working, a double-sealed heating furnace structure can be formed by setting an outer shell 1 on the outside of the heating box 5. A reinforcing block 7 and a support frame 8 are set on the inner side of the outer shell 1 to improve the deformation resistance of the outer shell 1. In actual operation, the starting of the servo motor 61 drives the threaded column 62 to rotate, causing the displacement platform 63 to move horizontally in the rotation of the threaded column 62, causing the heating box 5 and the sealing door 21 to be extended as a whole, so as to load or unload materials into the heating box 5. After loading, the heating box 5 and the sealing door 21 are reset, so that the heating box 5 is put into the outer shell 1. The sealing door 21 drives the four sets of calibration blocks 22 to calibrate and engage with the calibration slots 24, so that the sealing door 21 is stably sealed and spliced with the outer shell 1, allowing the heating box 5 to operate stably under double-sealed protection.
[0036] When the sealing door panel 21 is closed and sealed with the outer shell 1, the starting of the motor 41 drives the rotating rod 42 and the first bevel gear 43 to rotate, and the first bevel gear 43 meshes synchronously with the two sets of second bevel gears 44. Then, the two sets of threaded rods 45 rotate synchronously. At this time, the positioning tube 48 can be lowered by the rotation of the first bevel gear 43 and contacted and fixed with the positioning recess 51 on the top surface of the heating box 5. The internal threaded tube 46 moves horizontally with the rotation of the threaded rod 45, thereby driving the connecting arm 47 and the locking rod 49 to engage with the locking hole 23 on the inner side of the calibration block 22 and the calibration groove 24 after the assembly. This makes the locking rod 49 engage and fix with the locking hole 23, further improving the sealing and fixing effect of the sealing door panel 21 and increasing the stability and protection effect of the vacuum environment operation of the heating furnace.
