Description

Technical Field

[0001] This utility model relates to the field of vacuum furnace technology, and specifically to a vacuum furnace. Background Technology

[0002] A vacuum furnace is a piece of equipment used for processes such as heating, sintering, and annealing, and is widely used in fields such as semiconductors, aerospace, new materials, and metallurgy.

[0003] Some internal components of a vacuum furnace require motor drive. Currently, existing vacuum furnaces often install motors outside the furnace body, extending the motor shaft through the side wall or door of the furnace body to connect with the driven components. This results in an excessively long motor shaft, affecting the stability of motor operation. Even if the motor is installed inside the furnace body, holes need to be drilled in the side wall or door of the furnace body to extend the motor wires to the outside for connection. Regardless of whether the motor is installed inside or outside the furnace body, the parts through which the motor components pass need to be sealed, increasing costs. When the motor needs maintenance, disassembly is very cumbersome. Utility Model Content

[0033] like Figures 1 to 4 As shown, this utility model provides a vacuum furnace, including a furnace body 100, a furnace door 101, a motor 102, a sealing flange 200, and an aviation plug 300;

[0034] A furnace door 101 is provided on one side of the furnace body 100, and a chamber is formed inside the furnace body 100, where the motor 102 is located;

[0035] The furnace door 101 is equipped with a sealing flange 200, and the sealing flange 200 has a mounting hole 201;

[0036] The aviation plug 300 includes a fixed section 301 and a first plug section 302. The fixed section 301 is fixed in the mounting hole 201. One end of the first plug section 302 is connected to the motor wire 103 of the motor 102, and the other end is detachably plugged into the end of the fixed section 301 facing the cavity.

[0037] In this embodiment, the vacuum furnace includes a furnace body 100, a furnace door 101, a motor 102, a sealing flange 200, and an aviation connector 300. The furnace body 100 forms an interior chamber, and the motor 102 is installed inside the chamber. A furnace door 101 is located on one side of the furnace body 100, and a sealing flange 200 is installed on the furnace door 101. The sealing flange 200 has a mounting hole 201 for mounting the fixing section 301 of the aviation connector 300. By fixing the fixing section 301 of the aviation connector 300 to the mounting hole 201, and in conjunction with the sealing flange 200, the vacuum furnace's sealing performance during use can be guaranteed. Meanwhile, the aviation plug 300 also includes a first plug section 302 that can be detachably plugged into the fixed section 301. One end of the first plug section 302 is connected to the motor wire 103 of the motor 102, and the other end is detachably plugged into the end of the fixed section 301 facing the chamber. When the motor 102 needs maintenance, it is only necessary to open the furnace door 101 and pull out the corresponding first plug section 302 from the fixed end to remove the motor 102 from the furnace body 100 for maintenance, which is very convenient. Since the fixed section 301 is always fixedly installed on the sealing flange 200, there is no need to consider the sealing problem caused by disassembly.

[0038] Of course, the aviation plug 300 and sealing flange 200 have good sealing performance, so they will not affect the sealing environment inside the furnace body 100 during use.

[0039] According to one embodiment provided by this utility model, such as Figure 2 , Figure 3 and Figure 4 As shown, the aviation plug 300 also includes a second plug section 303, the end of which is detachably plugged into the end of the fixed section 301 that is away from the end of the first plug section 302.

[0040] In this embodiment, the aviation plug 300 also includes a second plug section 303. The end of the second plug section 303 can be detachably connected to the end of the fixed section 301 away from the first plug section 302 (i.e. the end located outside the chamber), thereby achieving the effect of connecting the motor 102 to the outside of the furnace body 100, avoiding redundant wires, and improving the overall aesthetics.

[0041] Of course, the end of the fixed segment 301 facing the first plug-in segment 302 is the male pin end, and the end of the fixed segment 301 facing the second plug-in segment 303 is the female pin end. Correspondingly, the end of the first plug-in segment 302 facing the fixed segment 301 is the female pin end, and the end of the second plug-in segment 303 facing the fixed segment 301 is the male pin end. The quick and detachable plug-in of the male pin end and the female pin end enables quick plugging and detachment between the first plug-in segment 302 and the fixed segment 301, and between the second plug-in segment 303 and the fixed segment 301.

[0042] According to one embodiment provided by this utility model, such as Figure 3 and Figure 4 As shown, the two ends of the fixed section 301 are respectively provided with a first identification point 304 and a second identification point 305, the end of the first plug-in section 302 opposite to the fixed section 301 is provided with a third identification point 306, and the end of the second plug-in section 303 opposite to the fixed section 301 is provided with a fourth identification point 307.

[0043] In this embodiment, the two ends of the fixed section 301 are respectively provided with a first identification point 304 and a second identification point 305. The first identification point 304 and the second identification point 305 are symmetrically arranged. Preferably, the end of the fixed section 301 facing the first insertion section 302 is the first identification point 304, and the end of the fixed section 301 facing the second insertion section 303 is the second identification point 305. A third identification point 306 is provided at the end of the first insertion section 302 opposite to the fixed section 301, and a fourth identification point 307 is provided at the end of the second insertion section 303 opposite to the fixed section 301. In use, the fixed section 301 is fixedly installed in the mounting hole 201, and the first identification point 304 and the second identification point 305 are kept facing upwards synchronously. When plugging in, the orientation of the third identification point 306 and the fourth identification point 307 is kept consistent with the orientation of the first identification point 304 and the second identification point 305, so as to ensure that the wiring error will not occur during plugging in and affect the normal use of the motor 102.

[0044] According to one embodiment provided by this utility model, such as Figure 3 and Figure 4 As shown, the first marker point 304, the second marker point 305, the third marker point 306, and the fourth marker point 307 are circular, rhomboid, or square.

[0045] In this embodiment, for easy visibility, the shapes of the first marker 304, the second marker 305, the third marker 306, and the fourth marker 307 include, but are not limited to, circles, rhombuses, or squares. Correspondingly, they can also be set to bright colors, such as red, so that they can be quickly identified during use.

[0046] According to one embodiment provided by this utility model, such as Figure 2 , Figure 3 and Figure 4 As shown, the outer wall of the fixing section 301 is arc-shaped and has threads. The fixing section 301 is fixed to the mounting hole 201 by a nut.

[0047] In this embodiment, the outer wall of the fixing section 301 is arc-shaped. Of course, the outer walls of the first insertion section 302 and the second insertion section 303 are also arc-shaped. Threads are provided circumferentially on the outer wall of the fixing section 301 so that the fixing section 301 can be fixed to the mounting hole 201 by a nut. The nut and the thread engage to fix the fixing section 301 to the mounting hole 201 opened in the sealing flange 200.

[0048] According to one embodiment of the present invention, the outer sidewall of the fixing segment 301 is provided with a set of opposing first planes along its own radial direction, and the inner sidewall of the mounting hole 201 is provided with a set of opposing second planes along its own radial direction. When the fixing segment 301 is located in the mounting hole 201, the first plane is in contact with the second plane.

[0049] In this embodiment, the outer side wall of the fixing segment 301 is provided with a set of opposing first planes, that is, symmetrically arranged along its own radial direction. Similarly, the inner side wall of the mounting hole 201 is provided with a set of opposing second planes, that is, symmetrically arranged along its own radial direction. When the fixing segment 301 is placed in the mounting hole 201, by fitting the first plane against the second plane and then tightening it with a nut in the threaded engagement of its side wall, the fixing segment 301 will not rotate, thereby ensuring that the first marking point 304 and the second marking point 305 can maintain their orientation during placement without change, so as to facilitate identification during subsequent insertion.

[0050] According to one embodiment provided by this utility model, such as Figure 1 As shown, the motor 102 is also equipped with a water cooling pipe 104, and the end of the water cooling pipe 104 away from the motor 102 extends to the outside of the furnace body 100 through a sealing flange 200.

[0051] In this embodiment, in order to ensure the performance of the motor 102, the motor 102 is also equipped with a water-cooling pipe 104. The water-cooling pipe 104 is extended to the outside of the furnace body 100 through the sealing flange 200. That is, one end of the water-cooling pipe 104 is connected to the motor 102, and the other end extends to the outside of the furnace body 100 through the sealing flange 200. By setting the water-cooling pipe 104, heat dissipation can be achieved efficiently, the power density of the motor 102 can be increased, the service life of the motor 102 can be further extended, and the performance can be stabilized to ensure the quality of the vacuum furnace.

[0052] According to one embodiment provided by this utility model, such as Figure 1 As shown, the sealing flange 200 also has a connection hole for installing the water cooling pipe 104.

[0053] In this embodiment, the water-cooling pipe 104 is welded and fixed through the connection hole opened in the sealing flange 200, so as to facilitate connection to the outside, without affecting the sealing of the furnace body 100.

[0054] According to one embodiment of the present invention, the motor wire 103 and the water cooling pipe 104 are bound together by a strap.

[0055] In this embodiment, in order to ensure the aesthetics of the internal structure and to prevent the motor wire 103 from shaking and affecting the use of the motor 102 during use, the motor wire 103 and the water cooling pipe 104 are bound together with a strap.

[0056] According to one embodiment provided by this utility model, such as Figure 1 As shown, the motor 102 is covered with a protective shell 105.

[0057] In this embodiment, the motor 102 is installed and fixed at a dedicated installation position near the furnace door 101, and a protective shell 105 is installed on the outside of the motor 102 to prevent the high temperature of the furnace body 100 from damaging the motor 102 and to extend the service life of the motor 102.

[0058] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
