Description

Technical Field

[0001] The present invention relates to the technical field of autoclaves, and specifically to a double-door structure of an autoclave door. Background Art

[0002] As the main production equipment for aerospace composite parts, an autoclave is a large plastic pressure vessel with an integral heating system and a structure of a nose plastic autoclave. Since an autoclave is a pressure vessel, its common structure is a cylinder with one end closed and the other end open, providing the necessary heat and pressure for the compaction and curing of advanced composite parts. Usually, the sizes of aerospace composite parts are very large, so the autoclave must be larger. At the same time, some composite forming requires higher pressure and temperature. In response to this situation, special autoclaves need to be built, but the cost will be quite high. Fortunately, most applications only require medium temperature and pressure.

[0003] Most of the existing autoclave structures adopt the opening and closing of a single-side door, that is, both loading and unloading of blanks are carried out through one tank opening, which not only causes trouble in loading and unloading, but also reduces the loading speed. In addition, there will be gaps after the door is closed with the tank body, and loosening and a decline in sealing performance will occur over time, thus affecting the working performance of the tank body itself.

[0004] Therefore, those skilled in the art have provided a double-door structure of an autoclave door to solve the problems raised in the above background art. Summary of the Invention

[0034] As shown in the accompanying drawings of the specification Figures 1 - 11 As shown, the present invention provides a structure of a double-opening tank door 2 for an autoclave, including a tank body 1 and tank doors 2 arranged on both sides thereof. On both sides of the tank body 1, an upper mounting plate 3 and a lower mounting plate 4 are sequentially arranged in parallel from high to low in the vertical direction. A rotating rod 5 is rotatably connected between the upper mounting plate 3 and the lower mounting plate 4 on each side of the tank body 1. A rotating block 6 connected to the tank door 2 is fixedly connected to the rotating rod 5. Above the upper mounting plate 3, a motor 7 fixedly connected to the rotating rod 5 is provided. The rotating rod 5 is a conventional rotating shaft structure. Tank doors 2 are opened on both sides of the tank body 1. By using two tank openings, the blank in the tank body 1 can be loaded and unloaded from two directions simultaneously, shortening the loading time and improving the loading speed and efficiency. During specific implementation, the motors 7 on both sides of the tank body 1 are respectively controlled to directly drive their rotation, thereby driving the rotating block 6 and the corresponding tank door 2 to rotate in the circumferential positive and negative directions along the central axis of the rotating rod 5, thereby realizing the opening and closing of the loading ports on both sides of the tank body 1 by the tank door 2;

[0035] As Figure 3 、 Figure 4As shown in the figure, in this embodiment, a first locking block 8 is fixedly connected to the side of the tank door 2 away from the rotating block 6. A first locking rod 9 is fixedly connected to the axial center of the rear end of the first locking block 8. A locking hole 10 is formed on the rear surface of the rear end of the first locking rod 9. Locking grooves 11 are symmetrically arranged on the outer surface of the first locking rod 9. A second locking block 12 is fixedly connected to the side of the tank body 1 away from the upper mounting plate 3. A sliding hole 13 that is slidably connected to the first locking rod 9 is formed on the surface of the second locking block 12. Electric push rods 14 are arranged on both the top wall and the bottom wall of the inner cavity of the second locking block 12. The output end of the electric push rod 14 is fixedly connected to a third locking block 15 that is adapted to be engaged with the locking groove 11. A second locking rod 16 that is inserted into the locking hole 10 of the first locking rod 9 is fixedly connected to the bottom wall of the inner cavity of the second locking block 12. During specific implementation, when the motor 7 drives the tank door 2 to rotate and approach the tank body 1 and close it against the tank body 1, the first locking rod 9 on the first locking block 8 slides into the inner cavity of the second locking block 12 through the sliding hole 13, and the second locking rod 16 in the inner cavity of the second locking block 12 is inserted into the locking hole 10 on the first locking rod 9 for preliminary locking. Then, the electric push rod 14 is activated to push the third locking block 15 into the locking groove 11 to achieve double locking. The self-locking fastening between the tank door 2 and the tank body 1 is realized through the locking between the first locking block 8 and the second locking block 12. When the tank door 2 closes the tank body 1, the tank door 2 and the tank body 1 are locked by the above-mentioned self-locking, so that the tank door 2 is closely attached to the tank body 1 to prevent it from loosening later, and the connection sealing performance between the tank door 2 and the tank body 1 can also be ensured, further improving the working safety performance.

[0036] As a preferred solution of the present invention, preferably, as Figure 5 shown, the rotating rod 5 rotates and extends out of the bottom of the lower mounting plate 4 and is fixedly connected to a guide plate 17. A plurality of guide rods 18 are annularly arranged on the outer side of the top of the guide plate 17. The top of each guide rod 18 is fixedly connected to a guide block 19. A guide ring 20 that is slidably connected to the guide block 19 is fixedly connected to the bottom of the mounting plate. When the motor 7 drives the rotating rod 5 to rotate, the rotating rod 5 drives the connected guide plate 17 to rotate synchronously. The guide plate 17 drives the guide block 19 to slide synchronously in the guide ring 20 through the guide rods 18, thereby guiding the rotation of the rotating rod 5 and the tank door 2, preventing the tank door 2 from rotating and shifting in position, and ensuring the movement stability of the rotating rod 5 and the tank door 2 during rotation.

[0037] As a preferred solution of the present invention, preferably, as Figure 8As shown in the figure, a number of positioning posts 21 are provided on the outer circumference of the rear end of the tank door 2. A positioning hole 22 is provided on the front surface of each positioning post 21. A number of positioning grooves 23 corresponding to the positioning posts 21 are provided on the outer circumference of one end of the tank body 1 corresponding to the tank door 2. A positioning rod 24 engaged with the positioning hole 22 is provided on the inner bottom wall of each positioning groove 23. A number of groups of positioning springs 25 are provided on the inner side wall of the positioning groove 23. Each group of positioning springs 25 is elastically connected to a positioning plate 26 that abuts against the outer wall of the positioning post 21. Specifically, when the tank door 2 completely closes the tank body 1, the positioning post 21 on the tank door 2 is inserted into the positioning groove 23 on the tank body 1. At this time, the positioning rod 24 on the tank body 1 is inserted into the positioning hole 22 on the positioning post 21, and the positioning spring 25 elastically expands and contracts to push the positioning plate 26 against the positioning post 21, realizing the fixation of the positioning post 21 in the positioning groove 23. In summary, in this embodiment, the auxiliary positioning between the tank door 2 and the tank body 1 can be realized by inserting the positioning post 21 into the positioning groove 23.

[0038] As a preferred solution of the present invention, preferably, as Figure 3 , Figure 7 , Figure 8 , Figure 9 shown, a first sealing strip 27 is annularly provided on the outer side wall of the tank door 2. A second sealing strip 28 that fits with the first sealing strip 27 is annularly provided on the outer side wall of one side of the tank body 1 corresponding to the tank door 2. A sealing block 29 is provided on the outer side of the rear end of the tank door 2. A number of sealing pads 30 are equidistantly provided on the outer side wall of the sealing block 29. The first sealing strip 27, the second sealing strip 28, the sealing block 29 and the sealing pads 30 are all made of rubber materials in the prior art. When the tank door 2 closes the tank body 1, the first sealing strip 27 and the second sealing strip 28 are fitted together to achieve the fitting and sealing of the two from the outside, and the sealing block 29 and the sealing pads 30 achieve the fitting and sealing of the two from the inside.

[0039] As a preferred solution of the present invention, preferably, as Figure 7 shown, a storage box 31 is provided in the middle of the rear end of the tank door 2. A buffer spring 32 is provided on the inner cavity bottom wall of the storage box 31. The buffer spring 32 is elastically connected to a placement plate 33. A buffer pad 34 is fitted on the top of the placement plate 33. The storage box 31 can increase the blank storage capacity of the inner cavity of the tank body 1. The blank can be placed in the storage box 31 for hot pressing when the tank door 2 closes the tank body 1, or other blanks or auxiliary tools for hot pressing of the tank body 1 can be placed. When specifically placing, the elastic expansion and contraction of the buffer spring 32 can buffer and damp the placed objects on the placement plate 33, thereby providing safety protection for them. And the buffer pad 34 can be used to prevent the placed objects from being directly placed on the placement plate 33 and causing wear, improving the protection performance.

[0040] As a preferred solution of the present invention, preferably, as Figure 1, Figure 6 , Figure 10 As shown in Figure 6 and Figure 10 , a pair of control handles 35 are provided in the middle of the front end of the tank door 2. Lifting rings 36 are fixedly connected to both sides of the front end of the tank door 2. By means of the control handles 35, it is convenient for manual pushing of the tank door 2 to cooperate with the motor 7 to drive its rotation, and the tank door 2 can be pulled and pushed to open and close on the tank body 1. And due to the arrangement of the lifting rings 36, it is convenient to use external lifting equipment to hoist and carry the tank body 1, facilitating its rapid movement. A display screen 37 is provided at the top of the front end of the tank door 2, and a temperature sensor 38 adapted thereto is provided at the top of the rear end of the tank door 2. The temperature sensor 38 is a prior art (it has its own detection module and detection feedback module, not shown). The temperature sensor 38 is electrically connected to the display screen 37. When the tank door 2 closes the tank body 1, the temperature sensor 38 can detect the real-time temperature inside the tank body 1 and feed the detected data back to the display screen 37 on the tank door 2, providing the staff with the real-time working temperature inside the tank body 1.

[0041] Working principle:

[0042] As shown in the attached drawings of the specification Figures 1 - 11 As shown in Figures 1 - 11 , the tank body 1 together with the tank door 2 is hoisted to the working location by using the lifting rings 36. By controlling the opening and closing of the motor 7, the rotating rod 5 is driven to rotate forward and backward. The rotation of the rotating rod 5 drives the rotating block 6 and the tank door 2 to rotate on the tank body 1, realizing the opening and closing of the tank door 2 on the tank body 1, and then cooperating with it to load and unload the blank. When carrying out the loading work, the rotation of the tank door 2 can be controlled by means of the control handle 35. When the tank door 2 rotates to close with the tank body 1, the first sealing strip 27 is attached to the second sealing strip 28 to achieve external sealing, and the first locking rod 9 on the first locking block 8 slides into the inner cavity of the second locking block 12 along the sliding hole 13. When the tank door 2 is completely attached to the tank body 1, the first locking rod 9 completely slides into the inner cavity of the second locking block 12. At this time, the second locking rod 16 in the second locking block 12 is inserted into the locking hole 10 on the first locking rod 9. Then, the electric push rod 14 is opened to push the third locking block 15 into the locking groove 11, realizing the locking between the first locking block 8 and the second locking block 12, and also realizing the self-locking between the tank body 1 and the tank door 2. In addition, the positioning post 21 on the tank door 2 is inserted into the positioning groove 23 on the tank body 1 to achieve the auxiliary positioning between the tank body 1 and the tank door 2. When the tank door 2 closes the tank body 1, the temperature sensor 38 on the tank door 2 can detect the real-time temperature and the temperature change value during the hot pressing work inside the tank body 1, and feed it back to the staff through the display screen 37, enabling them to understand the working temperature inside the tank body 1 in the first time.

[0043] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes, shall be covered by the protection scope of the present invention.
