[0050] like Figure 1 As shown, the embodiment of the present application provides a furnace door sealing ring installation device (hereinafter referred to as the installation device), including a fixing rod 1, an extrusion assembly 2 and a driving device 3, one end of the extrusion assembly 2 is provided with a first extrusion member 21 and a second extrusion member 22, and there is a gap a between the second extrusion member 22 and the first extrusion member 21, and at least part of the surface of the first extrusion member 21 and the second extrusion member 22 located in the gap a is used to extrude the sealing ring 5. Among them, the sealing ring 5 is used to be installed on the furnace door of the high-temperature vacuum equipment, and of course it can also be installed on other equipment that requires the sealing ring, which is not specifically limited in this embodiment. This embodiment is described by taking the installation of the sealing ring 5 on the furnace door of the high-temperature vacuum equipment as an example.

[0051] The driving device 3 is connected to the fixed rod 1, and the driving part of the driving device 3 is connected to one end of the extrusion assembly 2 away from the first extrusion piece 21 and the second extrusion piece 22, and is used to drive the extrusion assembly 2 to rotate around the fixed rod 1. Among them, the fixed rod 1 can realize the supporting effect on the installation device as a whole, and ensure the stability of the installation device in application. Among them, the fixed rod can be a hollow tubular structure, so as to reduce the overall weight of the installation device, realize a lightweight design, and facilitate user operation. The driving device 3 can be a driving motor, and the base of the driving motor can be installed on the fixed rod 1. The driving motor can provide a driving force to drive the extrusion assembly as a whole to rotate in a circle with the fixed rod as the rotation center.

[0052] like Figure 2As shown, when the installation device provided by this embodiment is used to install the sealing ring 5, in order to facilitate the installation operation, the furnace door 4 can be placed as a whole on the table or the ground, so that the inner surface of the furnace door 4 with the sealing groove 41 faces the direction away from the table or the ground. Then, the sealing ring 5 can be placed above the sealing groove 41, so that the sealing ring 5 and the sealing groove 41 are opposite to each other to achieve pre-alignment. Using the installation device provided by this embodiment, the fixing rod 1 is stably supported at the center position of the furnace door 4 in the thickness direction Z of the furnace door 4, ensuring that the center line of the fixing rod 1 coincides with the center line of the furnace door 4. At this time, the interval a between the first extrusion member 21 and the second extrusion member 22 can be aligned with the sealing ring 5 in the thickness direction Z of the furnace door 4, and at least part of the surface of the first extrusion member 21 and the second extrusion member 22 located in the interval a can be squeezed at the edge of the sealing ring 5, so that the part of the sealing ring 5 squeezed by the first extrusion member 21 and the second extrusion member 22 can be embedded in the sealing groove 41 of the furnace door 4. Then, the driving device 3 can be started, and the driving device 3 can drive the extrusion assembly 2 to rotate around the fixed rod 1. During the rotation of the extrusion assembly 2, the first extrusion member 21 and the second extrusion member 22 are kept in an extrusion state with the sealing ring 5, so that the extrusion assembly 2 can rotate, for example, after rotating 360°. Figure 3 As shown, each position of the sealing ring 5 can be squeezed into the sealing groove 41 by the first extrusion piece 21 and the second extrusion piece 22 , thereby completing the installation of the sealing ring 5 .

[0053] Therefore, the installation device provided in the embodiment of the present application can realize the automated installation of the sealing ring 5, thereby releasing manpower and improving the installation efficiency.

[0054] As a specific implementation, the first extrusion member 21 includes a first extrusion surface 211, and the second extrusion member 22 includes a second extrusion surface 221, and there is a gap a between the first extrusion surface 211 and the second extrusion surface 221. The first extrusion surface 211 and the second extrusion surface 221 are inclined surfaces or curved surfaces. When the first extrusion surface 211 and the second extrusion surface 221 are inclined surfaces, the extension surfaces of the two inclined surfaces intersect in a direction away from the sealing ring 5, so that the inclined surface can be extruded on the edge of the sealing ring 5 away from the furnace door 4, and can provide a component force toward the side of the furnace door 4 for the sealing ring 5, and the component force can be used to extrude the sealing ring 5 into the sealing groove 41 on the furnace door 4. In addition, when the first extrusion surface 211 and the second extrusion surface 221 are curved surfaces, the tangents of the two curved surfaces intersect in a direction away from the sealing ring 5, so that the curved surface can also provide a component force toward the side of the furnace door 4 for the sealing ring 5, so that the sealing ring 5 can be extruded into the sealing groove 41. In some other embodiments, one of the first extrusion surface 211 and the second extrusion surface 221 may have the above-mentioned inclined surface, and the other may have the above-mentioned curved surface, which may also realize extruding the sealing ring 5 into the sealing groove 41 .

[0055] As a specific implementation, the extrusion assembly 2 includes a connecting rod 23, one end of the connecting rod 23 is connected to the driving part of the driving device 3, and the end of the connecting rod 23 away from the driving device 3 is connected to the first extrusion member 21 and the second extrusion member 22. The connecting rod 23 has a certain length, and its length can be designed according to the dimensional parameters such as the diameter and wall thickness of the sealing ring 5, so that the first extrusion member 21 and the second extrusion member 22 can be extruded on the edge of the sealing ring 5. In one embodiment, the connecting rod 23 can be a tubular structure, a rod structure, a plate structure, etc., and the specific shape can be designed according to actual needs, with strong design flexibility. In addition, the material of the connecting rod 23 can be a metal material, a hard plastic, etc. The specific material is based on ensuring the structural strength of the connecting rod 23, and this embodiment is not limited to this.

[0056] As a specific implementation method, Figure 4 As shown, the connecting rod 23 may include a first rod 231, a second rod 232 and a third rod 233, and one end of the first rod 231 is connected to the driving part of the driving device 3. The second rod 232 and the third rod 233 are both connected to one end of the first rod 231 away from the driving device 3. One end of the second rod 232 away from the first rod 231 is connected to the first extrusion member 21, and one end of the third rod 233 away from the first rod 231 is connected to the second extrusion member 22. Among them, the first rod 231 can realize that the first extrusion member 21 and the second extrusion member 22 can be aligned with the corresponding position of the sealing ring 5 in the thickness direction of the furnace door 4. There is a certain distance between the second rod 232 and the third rod 233, which can facilitate the connection with the corresponding first extrusion member 21 and the second extrusion member 22 on the one hand, and can form a gap a between the first extrusion member 21 and the second extrusion member 22 on the other hand, which is conducive to providing space for the compression deformation of the sealing ring 5.

[0057] As a specific implementation, the first rod 231, the second rod 232 and the third rod 233 can be an integrally formed structure, so as to facilitate processing and manufacturing, and also facilitate assembly in the installation device. As a specific implementation, at least one of the second rod 232 and the third rod 233 can be adjustably connected to the first rod 231 through a connecting member. Among them, the connecting member can be a bolt, a nut, etc., illustratively, a threaded hole can be provided on the first rod 231, and a through hole can be provided on the second rod 232 and the third rod 233. The screw can be fastened in the threaded hole by passing through the through hole, and the nut can lock and position the screw with the first rod 231, so that the distance between the second rod 232 and the third rod 233 can be adjusted by adjusting the depth of the screw screwed into the threaded hole, and then the width of the interval a can be adjusted, so that the first extrusion member 21 and the second extrusion member 22 can meet the extrusion requirements of the sealing ring 5 with different wall thicknesses.

[0058] As a specific implementation, the first rod 231 may be L-shaped. Exemplarily, the first rod 231 includes a first section and a second section, the first section extends in a direction away from the fixed rod 1, and the second section and the first section have an angle, for example, the angle may be 90°, that is, the first section and the second section are perpendicular, the first section may ensure that the first extrusion 21 and the second extrusion 22 can be aligned with the sealing ring 5 in the thickness direction of the furnace door 4, and the second section may realize that the first extrusion 21 and the second extrusion 22 are extruded on the sealing ring 5. Among them, the first rod 231 may be an integrally formed structure, and the first section and the second section may be designed to match the dimensional parameters of the sealing ring 5, such as the diameter and wall thickness.

[0059] As a specific implementation, the first rod 231 itself is a retractable structure. For example, the first rod 231 includes a first adjustment section and a second adjustment section. The first adjustment section and the second adjustment section can be hollow tubular structures. The first adjustment section can be retractably arranged in the second adjustment section, so that the distance between the first extrusion member 21 and the second extrusion member 22 and the fixed rod 1 can be adjusted by the cooperation of the first adjustment section and the second adjustment section, so that the installation device can meet the extrusion requirements of the sealing ring 5 with different diameters. Among them, the first adjustment section and the second adjustment section can be positioned by a connecting member such as a screw. In some other embodiments, the first rod 231 can also include more adjustment sections, and the two adjacent adjustment sections can be retractably connected, which is not limited in this embodiment. In a specific embodiment, as described above, the first rod 231 can include a first section and a second section that are perpendicular to each other, wherein the first section can be a retractable structure, that is, the first section includes the aforementioned multiple adjustment sections, and the two adjacent adjustment sections can be retracted to adjust the length of the first section, so that the extrusion installation of the sealing ring with different diameters can be realized.

[0060] As a specific implementation, as described above, the second section can also be a retractable structure. Exemplarily, the second section can include multiple first telescopic sections, the first telescopic section can be a hollow structure, and one first telescopic section can be connected with another adjacent first telescopic section so that the two adjacent first telescopic sections can be relatively telescopic. Since the second section as a whole can extend in the same direction as the fixed rod 1, the length of the second section as a whole can be adjusted by the first telescopic section, so that the distance between the first extrusion member 21 and the second extrusion member 22 and the sealing ring 5 can be adjusted, so that the first extrusion member 21 and the second extrusion member 22 can be squeezed on the sealing ring 5, and can provide appropriate squeezing force to squeeze the sealing ring 5 into the sealing groove of the furnace door. Among them, a plurality of positioning holes can be provided on the first telescopic section, so that when the two adjacent first telescopic sections are adjusted to different relative positions, the two adjacent first telescopic sections have positioning holes that can be aligned with each other, and can further be locked by inserting positioning pins in the two aligned positioning holes to ensure that the second section as a whole has a stable length during operation. As a specific implementation, the fixed rod 1 can be a telescopic structure, and the fixed rod 1 can include multiple second telescopic sections, and the second telescopic sections can be hollow tubes. One second telescopic section can be connected to another adjacent second telescopic section in a sleeve connection, so that the two adjacent second telescopic sections can be relatively telescopic, and one of the second telescopic sections can be connected to the extrusion assembly 2, and can drive the extrusion assembly 2 as a whole to move in the length direction of the fixed rod 1, so that the first extrusion member 21 and the second extrusion member 22 can be moved closer to or away from the sealing ring 5, so as to adjust the extrusion force between the first extrusion member 21 and the second extrusion member 22 and the sealing ring 5. In one embodiment, the two sleeved second telescopic sections can be locked and positioned by bolts, or the two sleeved second telescopic sections can be clamped and positioned by pipe clamps, or the two sleeved second telescopic sections can be clamped and positioned by latches. This embodiment does not limit the specific locking form of the two sleeved second telescopic sections.

[0061] As a specific implementation method, the first extrusion member 21 and the second extrusion member 22 can be fixedly connected to the connecting rod 23, for example, fixedly connected by connecting members such as screws, so as to ensure the reliability of the installation of the first extrusion member 21 and the second extrusion member 22. However, in the process of the extrusion assembly 2 rotating around the fixed rod 1 as a whole, the first extrusion member 21 and the second extrusion member 22 using the above-mentioned fixed connection method will generate sliding friction with the sealing ring 5, which will bring the risk of wear to the sealing ring 5. To this end, in one embodiment, at least one of the first extrusion member 21 and the second extrusion member 22 can be rotatably connected to the connecting rod 23, wherein only one of the first extrusion member 21 and the second extrusion member 22 can be rotatably connected to the connecting rod 23, or both of the first extrusion member 21 and the second extrusion member 22 can be rotatably connected to the connecting rod 23. In this embodiment, taking the example that the first extrusion member 21 and the second extrusion member 22 are both rotatably connected to the connecting rod 23, during the overall rotation of the extrusion assembly 2 around the fixed rod 1, there is rolling friction between the first extrusion member 21 and the second extrusion member 22 and the sealing ring 5, and the first extrusion member 21 and the second extrusion member 22 can rotate on their own, thereby reducing the wear on the sealing ring 5.

[0062] As a specific implementation method, the first extrusion member 21 and the second extrusion member 22 can both be rollers, pressure rollers or balls. During the overall rotation of the extrusion assembly 2, the rollers, pressure rollers or balls can rotate on their own, generating rolling friction between them and the sealing ring 5, thereby reducing the wear on the sealing ring 5.

[0063] As a specific implementation, the first extrusion member 21 and the second extrusion member 22 are both rotatably connected to the connecting rod 23 via a bearing. The bearing can be fixedly connected to the connecting rod 23 on one hand, and can be rotatably connected to the first extrusion member 21 or the second extrusion member 22 on the other hand, thereby facilitating the installation of the first extrusion member 21, the second extrusion member 22 and the connecting rod 23, and also realizing the self-rotation of the first extrusion member 21 and the second extrusion member 22, so as to reduce the wear on the sealing ring 5.

[0064] As a specific implementation, the installation device further includes a detection device, which can be, for example, a displacement sensor, etc. The detection device can be installed in the extrusion assembly 2 to detect the flatness of the sealing ring 5. That is, after the sealing ring 5 is extruded into the sealing groove 41 by the first extrusion member 21 and the second extrusion member 22, the detection device can detect the flatness of the sealing ring 5 installed in the sealing groove 41, thereby ensuring the installation quality of the sealing ring 5.

[0065] As a specific implementation method, Figure 2As shown, a recessed structure 11 may be provided at one end of the fixing rod 1, and a protruding structure 42 may be provided on the furnace door 4. The recessed structure 11 may cooperate with the protruding structure 42, so that the fixing rod 1 may be positioned on the furnace door 4, and the stability of the fixing rod 1 on the furnace door 4 may be ensured. In one embodiment, the recessed structure may be a hole, and the protruding structure may be a columnar structure. The hole may be sleeved on the columnar structure. The positioning of the fixing rod may be achieved through the cooperation of the hole and the columnar structure, and the stability of the fixing rod during operation may be ensured. In one embodiment, a screw may be provided on the furnace door, and the screw nut may protrude from the surface of the furnace door, that is, the nut may serve as the above-mentioned protruding structure, and the inner surface of the recessed structure may have a similar shape to the surface of the nut. For example, the surface of the nut is an arcuate surface, and the inner surface of the recessed structure may also be an arcuate surface, so that the inner surface of the recessed structure may fit the surface of the nut, and the stability of the fixing rod may be ensured.

[0066] In one embodiment, the fixing rod 1 may be provided with a magnetic attraction member, such as a magnet, an electromagnet, etc., and the fixing rod 1 may be fixed to the furnace door by adsorption of the magnetic attraction member, so that the user does not need to manually support the installation device, which is convenient for operation and saves manpower. The furnace door may also be provided with the above-mentioned magnetic attraction member, or may be provided with a metal part that can be adsorbed by a magnet, which is not limited in this embodiment.

[0067] The above description is only an optional embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
