Description
Technical Field
[0001] This application relates to the field of aluminum alloy processing technology, specifically to an auxiliary device for reducing the pinholes of aluminum alloys. Background Technology
[0002] Aluminum alloys are widely used in aerospace, automotive manufacturing, and other fields, but their surface pinholes are often a key factor restricting quality improvement. To effectively reduce the pinholes of aluminum alloys, this device combines advanced testing methods and processing technologies, significantly improving the surface quality of aluminum alloys.
[0003] After the aluminum alloy material has been cleaned and polished, it is then placed in a vacuum furnace for heat treatment. By precisely controlling the temperature and time, internal stress is further eliminated, the microstructure is improved, and the pinholes are reduced.
[0004] Multiple groups of aluminum alloy materials are placed alternately on the placement platform of the vacuum furnace. The closer to the inside of the vacuum furnace, the more personnel need to enter the vacuum furnace during placement. After the aluminum alloy materials have undergone heat treatment inside the vacuum furnace and the furnace has cooled down, personnel need to enter the vacuum furnace again to remove the innermost aluminum alloy materials. During the process of bending over to pick them up, friction scratches are easily caused between the surface of the aluminum alloy materials and the placement platform. Utility Model Content

[0006] To achieve the above objectives, this application provides the following technical solution: an aluminum alloy pinhole reduction auxiliary device, comprising: a vacuum heat treatment device body, a placement table, a sliding platform assembly, a limiting assembly, and a lifting platform assembly.

There are two sets of mounting plates. A first rod is vertically slidably connected inside the mounting plate, a trapezoidal locking block welded to the top of the first rod, a first spring sleeved on the first rod, and a handle welded to the bottom outer wall of the trapezoidal locking block. A protrusion is integrally formed on the outer wall of the handle. A second slide rail is welded to the inner wall of the placement table, and the protrusion of the handle is slidably connected inside the second slide rail. The limiting assembly is disposed around the top of the first placement plate, and the lifting platform assembly is disposed above the limiting assembly.
[0007] By adopting the above technical solution, the quantity of aluminum alloy materials placed in each batch can be increased and the aluminum alloy materials can be slid out from inside the device, making it easier to remove the aluminum alloy materials without wear.
[0008] Preferably, the limiting component includes four sets of rectangular tubes welded around the top of the first placement plate. Each rectangular tube has a threaded hole inside, and a threaded rod is threadedly connected to the threaded hole of the first rectangular tube.
[0009] By adopting the above technical solution, the threaded connection enables movement during rotation.
[0010] Preferably, the lifting platform assembly includes a second placement plate disposed above the four sets of first rectangular tubes, a limit component disposed on the top of the second placement plate, and second rectangular tubes welded to the bottom of the second placement plate, the second rectangular tubes at the bottom of the second placement plate being inserted into the first rectangular tubes of the first placement plate.

[0015] By adopting the above technical solution, the insertion of the plug block can achieve the positioning of the No. 3 rectangular tube inside the No. 2 rectangular tube.
[0016] Preferably, the lifting platform assembly further includes a second spring sleeved on the second rod.
[0017] By adopting the above technical solution, the plug block can be displaced by its own elasticity.
[0018] In summary, this application has the following beneficial effects: by incorporating a sliding platform assembly, a limiting assembly, and a lifting platform assembly, the sliding platform assembly enables the aluminum alloy material placed on top to be quickly displaced from the interior of the device after processing, thus providing more space for personnel to remove the processed aluminum alloy material.

[0026] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0027] The following is in conjunction with the appendix Figure 1-6 The embodiments of this application will be described in further detail.
[0028] Example 1
[0029] Please see Figures 1-6 This embodiment provides a technical solution: an aluminum alloy pinhole reduction auxiliary device, comprising: a vacuum heat treatment device body 1, a placement table 2, a sliding platform assembly 3, a limiting assembly 4, and a lifting platform assembly 5;
[0030] The auxiliary cooling device includes a vacuum heat treatment device body 1 and a placement platform 2 disposed inside the vacuum heat treatment device body 1. The vacuum heat treatment device body 1 can provide a high vacuum condition, which allows the material to be rapidly heated to above the melting point. For metals, it can achieve non-oxidative melting, improve purity and performance. Different materials can undergo annealing, quenching and other treatments at specific temperatures and times. The vacuum environment helps to eliminate internal stress and improve the mechanical properties and microstructure of the material. The above is the prior art, and will not be described in detail below.
[0031] The sliding platform assembly 3 is positioned above the placement platform 2. The sliding platform assembly 3 includes a first slide rail 301 welded above the placement platform 2, a first placement plate 302 slidably connected to the first slide rail 301, a connecting rod 303 welded inside the first placement plate 302, mounting plates 304 fixed on both sides of the bottom outer wall of the placement platform 2, and two sets of mounting plates 304. A first rod 305 is vertically slidably connected inside the mounting plate 304, a trapezoidal locking block 306 welded to the top of the first rod 305, a first spring 307 sleeved on the first rod 305, a handle 308 welded to the bottom outer wall of the trapezoidal locking block 306, a protrusion integrally formed on the outer wall of the handle 308, a second slide rail 309 welded to the inner wall of the placement platform 2, and the protrusion of the handle 308 slidably connected to the inside of the second slide rail 309. A limiting assembly 4 is positioned around the top of the first placement plate 302, and a lifting platform assembly 5 is positioned above the limiting assembly 4.
[0032] The height of the lifting platform assembly 5 is adjusted according to the size of the aluminum alloy material. Then, the lifting platform assembly 5 is inserted into the limiting assembly 4 on the upper periphery of the sliding platform assembly 3. At this time, aluminum alloy materials can be placed above both the lifting platform assembly 5 and the sliding platform assembly 3. This can provide the quantity of aluminum alloy materials processed by the vacuum heat treatment device body 1 in each batch. The sliding platform assembly 3 can be slid into the vacuum heat treatment device body 1 through the placement table 2 to achieve subsequent processing.
[0033] After more aluminum alloy material is placed on the first placement plate 302 and the second placement plate 501, the first placement plate 302 on the first slide rail 301 of the placement platform 2 is pushed. During the displacement process, the first placement plate 302 can move out of the vacuum heat treatment device body 1 and then out of the vacuum heat treatment device body 1. When the first placement plate 302 moves to the designated position, during the horizontal displacement process, it can drive the internal connecting rod 303 to move horizontally as well. When the connecting rod 303 moves horizontally and contacts the trapezoidal locking block 306, the trapezoidal locking block 306 is pushed horizontally by the connecting rod 303, thereby generating... When the connecting rod 303 moves to the top center of the trapezoidal block 306, the trapezoidal block 306 is compressed by the first spring 307 outside the first rod 305. The first rod 305 can move stably vertically through the hole in the mounting plate 304. At this time, the trapezoidal block 306 will position the first placement plate 302 and the connecting rod 303. When it is necessary to slide the first placement plate 302 on the first slide rail 301, the handle 308 inside the second slide rail 309 is pressed. The handle 308 will drive the trapezoidal block 306 to move vertically downward, so that the trapezoidal block 306 will no longer position the connecting rod 303.
[0034] Example 2
[0035] Please see Figures 1-6 This embodiment provides a technical solution: an aluminum alloy pinhole reduction auxiliary device, comprising: a first rectangular tube 401 and a threaded rod 402;
[0036] The limiting component 4 includes four sets of rectangular tubes 401 welded around the top of the first placement plate 302. The first rectangular tubes 401 have threaded holes inside and threaded rods 402 are threadedly connected to the threaded holes of the first rectangular tubes 401.
[0037] The lower rectangular tube 504 is inserted into the interior of the first rectangular tube 401 above the first placement plate 302. The threaded rod 402 rotates and displaces the tube within the threaded hole of the first rectangular tube 401, thereby pressing and fitting the third rectangular tube 504 together. This fixes the second placement plate 501 above the first placement plate 302, allowing more aluminum alloy material to be placed between the first placement plate 302 and the second placement plate 501.
[0038] Example 3
[0039] Please see Figures 1-6 This embodiment provides a technical solution: an aluminum alloy pinhole reduction auxiliary device, including: a second placement plate 501, a second rectangular tube 502, an insertion hole 503, a third rectangular tube 504, a second rod 505, an insertion block 506, and a second spring 507.
[0040] The lifting platform assembly 5 includes a second placement plate 501 set above four sets of first rectangular tubes 401. A limit component 4 is set on the top of the second placement plate 501. Second rectangular tubes 502 are welded to the bottom of the second placement plate 501. The second rectangular tubes 502 at the bottom of the second placement plate 501 are inserted into the first rectangular tubes 401 of the first placement plate 302. A total of seven sets of insertion holes 503 are equidistantly opened on the outer wall of the second rectangular tubes 502. A third rectangular tube 504 is slidably connected inside the second rectangular tubes 502. The third rectangular tube 504 has a round hole inside.
[0041] The second rod 505 is welded to the inner wall of the third rectangular tube 504, and the plug block 506 is slidably connected to the second rod 505. The plug block 506 passes through the round hole and the plug hole 503 of the third rectangular tube 504, and the second spring 507 is sleeved on the second rod 505.
[0042] When it is necessary to adjust the distance between the second placement plate 501 and the first placement plate 302 according to the size of the aluminum alloy material, the insertion block 506 inside the insertion hole 503 of the second rectangular tube 502 is pressed. At this time, the insertion block 506 will move out of the insertion hole 503. The insertion block 506 will no longer be squeezed by the second spring 507 outside the second rod 505 and will no longer be inside the insertion hole 503. At this time, after sliding the third rectangular tube 504 inside the second rectangular tube 502 to the designated position, the insertion block 506 can be inserted into the insertion hole 503 for positioning by the squeeze of the second spring 507.
[0043] The implementation principle of the aluminum alloy pinhole reduction auxiliary device of this application is as follows:
[0044] First, adjust the height of the lifting platform assembly 5 according to the size of the aluminum alloy material. Then, insert the lifting platform assembly 5 into the limiting assembly 4 around the top of the sliding platform assembly 3. At this time, aluminum alloy materials can be placed above both the lifting platform assembly 5 and the sliding platform assembly 3. This can provide the quantity of aluminum alloy materials processed by the vacuum heat treatment device body 1 in each batch. The sliding platform assembly 3 can be slid into the vacuum heat treatment device body 1 through the placement table 2 to achieve subsequent processing.
[0045] Secondly, when it is necessary to adjust the distance between the second placement plate 501 and the first placement plate 302 according to the size of the aluminum alloy material, by pressing the insertion block 506 inside the insertion hole 503 of the second rectangular tube 502, the insertion block 506 will move out of the insertion hole 503. At this time, the insertion block 506 will no longer be squeezed by the second spring 507 outside the second rod 505, and will no longer be inside the insertion hole 503. Then, by sliding the third rectangular tube 504 inside the second rectangular tube 502 to the designated position, the insertion block 506 can be inserted into the insertion hole by the compression of the second spring 507. The inside of hole 503 is positioned. At this time, the second rectangular tube 502 and the third rectangular tube 504, which are fixed in position, form an integral pipe. The third rectangular tube 504, which is located at the bottom, is inserted into the first rectangular tube 401 above the first placement plate 302. The threaded rod 402 achieves rotational displacement in the threaded hole of the first rectangular tube 401. The threaded rod 402 squeezes and fits the third rectangular tube 504, thereby fixing the second placement plate 501 above the first placement plate 302. More aluminum alloy material can be placed through the first placement plate 302 and the second placement plate 501.
[0046] Finally, after placing more aluminum alloy material on the first placement plate 302 and the second placement plate 501, the first placement plate 302 on the first slide rail 301 of the placement platform 2 is pushed. During the displacement process, the first placement plate 302 can move out of the vacuum heat treatment device body 1 and then out of the vacuum heat treatment device body 1. When the first placement plate 302 moves to the designated position, during the horizontal displacement process, it can drive the internal connecting rod 303 to move horizontally as well. When the connecting rod 303 moves horizontally and contacts the trapezoidal locking block 306, the trapezoidal locking block 306 is pushed horizontally by the connecting rod 303, thereby producing... When the connecting rod 303 moves to the top center of the trapezoidal block 306, the trapezoidal block 306 is compressed by the first spring 307 outside the first rod 305, and the first rod 305 can move stably vertically through the hole in the mounting plate 304. At this time, the trapezoidal block 306 will position the first placement plate 302 and the connecting rod 303. When it is necessary to slide the first placement plate 302 on the first slide rail 301, the handle 308 inside the second slide rail 309 is pressed. The handle 308 will drive the trapezoidal block 306 to move vertically downward, so that the trapezoidal block 306 will no longer position the connecting rod 303.
[0047] It will be apparent to those skilled in the art that this application is not limited to the details of the exemplary embodiments described above, and that this application can be implemented in other specific forms without departing from the spirit or essential characteristics of this application. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this application is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this application.
