Therefore, the importance of aluminum surface polishing technology as a core process to improve its surface quality and aesthetics is self-evident.

[0003] At present, aluminum surface polishing mainly relies on two technical means: manual polishing and automated mechanical polishing.

[0039] The driving component 30 may be a telescopic cylinder.

[0040] The polishing assembly 40 includes a mounting plate 41 , an adjusting capsule 42 , a polishing layer 43 , an air pump component 44 and an air delivery pipe 45 .

[0041] The top surface of the mounting plate 41 is connected to the driving component 30 , and the bottom surface of the mounting plate 41 is connected to the regulating capsule 42 .

[0042] The polishing layer 43 is disposed on the bottom surface of the regulating capsule 42 .

[0043] The polishing layer 43 is a damping polishing cloth.

[0044] It should be noted that the regulating bladder 42 in this embodiment is filled with gas, and the gas pressure inside the regulating bladder 42 is selected according to actual needs, which will not be described in detail here.

[0045] The air pump component 44 is installed on the mounting plate 41 , the output end of the air pump component 44 is connected to the air delivery pipe 45 , and the input end of the air pump component 44 is communicated with the external space.

[0046] The air pump component 44 may be an air pump.

[0047] The interior of the mounting plate 41 is hollow, and one end of the air delivery pipe 45 away from the air pump component 44 passes through the mounting plate 41 and is communicated with the interior of the mounting plate 41 .

[0048] The air pressure detection element may be installed inside the mounting plate 41 .

[0049] The interior of the mounting plate 41 and the interior of the regulating bag 42 are communicated with each other.

[0050] It should be noted that the bottom surface of the mounting plate 41 and the top surface of the regulating bladder 42 are provided with communicating vents, and the interior of the mounting plate 41 and the interior of the regulating bladder 42 are communicated with each other through the vents.

[0051] In order to clearly explain the above embodiment, in one embodiment of the present application, Figure 1 and Figure 4 As shown, the clamping assembly 50 includes a clamping seat 51 , an abutment plate 52 and a plurality of adjustment screws 53 .

[0052] The clamping seat 51 may be a C-shaped structure, and the clamping seat 51 is slidably disposed on the driving rail 11 .

[0053] It should be noted that the aluminum material is positioned on the clamping seat 51 , and the clamping seat 51 is controlled to move by the driving track 11 , thereby driving the aluminum material to move.

[0054] The abutment plate 52 is located in the clamping seat 51 , and the bottom surface of the abutment plate 52 abuts against the inner bottom surface of the clamping seat 51 .

[0055] One end of the adjusting screw 53 is rotatably connected to the abutment plate 52 , and the other end of the adjusting screw 53 passes through the clamping seat 51 , and the adjusting screw 53 is threadedly connected to the clamping seat 51 .

[0056] The adjusting screw 53 can be rotatably connected to the contact plate 52 via a bearing.

[0057] It should be noted that the plurality of adjusting screws 53 may be 2, 3, 4, 5, 6 adjusting screws 53, etc. The specific number is selected according to actual needs and will not be described in detail here.

[0058] It should be noted that a rotating handle may be provided on the side of the adjusting screw 53 away from the abutment plate 52 to facilitate the relevant personnel to rotate it. The rotating handle is a prior art and will not be described in detail here.

[0059] Specifically, in the actual operation, the relevant personnel place the aluminum material on the clamping seat 51 of the clamping assembly 50, and adjust the clamping force between the contact plate 52 and the aluminum material by adjusting the screw 53 to ensure that the aluminum material does not move during the polishing process; start the drive track 11 and the drive component 30 to lower the polishing assembly 40 to the position in contact with the surface of the aluminum material. At the same time, start the pump gas component 44, and inflate the regulating capsule 42 through the air pipe 45 to make the polishing layer 43 fit tightly on the surface of the aluminum material; then, control the clamping assembly 50 to move the aluminum material through the drive track 11 to achieve comprehensive polishing of the aluminum material surface; after polishing is completed, close the drive track 11 and the pump gas component 44, lift the polishing assembly 40, and take out the aluminum material for the next step of processing.

[0060] By setting the adjusting capsule 42 and the polishing layer 43, the polishing force and the contact area can be adjusted according to actual needs, thereby ensuring the uniformity and consistency of the polishing effect; by adjusting the deformation of the capsule 42, the polishing layer 43 can be suitable for aluminum materials with uneven surfaces, thereby ensuring the comprehensiveness of aluminum polishing; by the coordinated use of the driving track 11 and the driving component 30, the continuous feeding of aluminum materials is achieved, thereby improving work efficiency; by adjusting the adaptive changes of the capsule 42, the equipment can adapt to the polishing needs of aluminum materials of different specifications and materials, and has high flexibility and versatility.

[0061] In one embodiment of the present application, Figure 5 , Figure 6 and Figure 7 As shown, the regulating capsule body 42 includes a plurality of unit capsules 421 , and the plurality of unit capsules 421 are arranged in a matrix.

[0062] The unit capsule 421 is made of elastic rubber.

[0063] It should be noted that the plurality of unit capsules 421 may be 80, 90, 100, 110, 120 unit capsules 421, etc. The specific number is selected according to actual needs and will not be described in detail here.

[0064] It should be noted that two adjacent unit capsules 421 in this embodiment are in contact with each other.

[0065] The interiors of the plurality of unit capsules 421 are respectively communicated with the interior of the mounting plate 41 .

[0066] It should be noted that the polishing layer 43 in this embodiment covers the end of the plurality of unit capsules 421 away from the mounting plate 41 .

[0067] It can be understood that during the polishing process, the air pump component 44 inflates the interior of the mounting plate 41 and the multiple unit capsules 421 through the air pipe 45, so that the polishing layer 43 fits tightly onto the surface of the aluminum material; due to the matrix arrangement and elastic rubber material of the unit capsules 421, the polishing layer 43 can be adaptively adjusted according to the shape and undulations of different aluminum surfaces, ensuring the uniformity of the polishing pressure and contact area.

[0068] By setting up multiple unit capsules 421, the polishing layer 43 can better fit the surface of the aluminum material, reducing the phenomenon of missed polishing and over-polishing during the polishing process, and significantly improving the polishing quality; the adaptive adjustment of the polishing assembly 40 reduces the pause and adjustment time during the polishing process, and improves work efficiency; the setting of multiple unit capsules 421 enables the polishing assembly 40 to adapt to aluminum materials of different shapes and sizes, and improves the versatility and flexibility of the equipment; the modular setting of the unit capsules 421 makes the replacement and cleaning of the polishing layer 43 more convenient, and reduces maintenance costs and time.

[0069] Further, in one embodiment of the present application, Figure 8 and Fig. 9 As shown, the polishing layer 43 includes a plurality of polishing sleeves 431 .

[0070] The polishing sleeves 431 are the same in number and correspond one to one with the unit capsules 421 , and the polishing sleeves 431 are sleeved on the outer wall of the corresponding unit capsule 421 .

[0071] The polishing sleeve 431 is made of damping polishing cloth.

[0072] It should be noted that the polishing sleeve 431 may be a cylindrical structure, and two adjacent polishing sleeves 431 abut against each other.

[0073] It should be noted that the damping polishing cloth has significant elasticity and good elongation and contraction properties (i.e., expansion and contraction properties).

[0074] It can be understood that during the polishing process, the air pump component 44 inflates the interior of the mounting plate 41 and the multiple unit capsules 421 through the air supply pipe 45, so that the polishing sleeve 431 fits tightly on the surface of the aluminum material; due to the one-to-one correspondence between the polishing sleeve 431 and the unit capsule 421, the unit capsule 421 can be adaptively adjusted according to the shape and undulation of the different aluminum surfaces, and the polishing sleeve 431 undergoes elastic deformation as the unit capsule 421 expands and contracts, and the dead angle of aluminum polishing is reduced; at the same time, the use of damping polishing cloth makes the polishing process smoother and more uniform, reducing the impact of vibration and impact force on the aluminum surface; the coordinated use of the drive track 11 and the drive component 30 realizes the continuous feeding of the aluminum material and the up and down movement of the polishing assembly 40, thereby completing the comprehensive polishing of the aluminum surface.

[0075] The independent setting of the polishing sleeve 431 and the use of the damping polishing cloth enable the polishing layer 43 to better fit the surface of the aluminum material, reduce interference and uneven friction during the polishing process, and significantly improve the polishing quality; the adaptive adjustment of the polishing assembly 40 and the shock-absorbing performance of the damping polishing cloth reduce the pause and adjustment time during the polishing process and improve work efficiency; the one-to-one correspondence between the polishing sleeve 431 and the unit capsule 421 enables the polishing assembly 40 to adapt to aluminum materials of different shapes and sizes, improving the versatility and flexibility of the equipment; the use of the damping polishing cloth effectively controls the vibration and impact force during the polishing process, protects the surface of the aluminum material from damage, and at the same time improves the stability and safety of the polishing process.

[0076] Further, in one embodiment of the present application, Fig. 9 As shown, an inner hole 422 is formed at one end of the unit capsule 421 away from the mounting plate 41 .

[0077] The polishing sleeve 431 is provided with an air injection hole 432 , and the air injection hole 432 is communicated with the inner hole 422 .

[0078] It should be noted that the internal space of the unit capsule 421 is connected to the external space through the inner hole 422 and the air injection hole 432 .

[0079] It should be noted that the aperture sizes of the inner hole 422 and the air injection hole 432 are selected according to actual needs and will not be described in detail here.

[0080] It is understandable that during the polishing process, the pumping component 44 inflates the interior of the mounting plate 41 and the interior of the plurality of unit capsules 421 through the gas delivery pipe 45. Due to the connectivity between the inner hole 422 and the jet hole 432, external gas can enter the gap between the polishing sleeve 431 and the aluminum surface through the jet hole 432. Through the flow of such gas, not only the contact state between the polishing sleeve 431 and the aluminum surface can be improved, but also the heat and debris generated during the polishing process can be taken away; at the same time, by adjusting the aperture size of the inner hole 422 and the jet hole 432, the polishing effect can be further optimized.

[0081] It should be noted that by controlling the pumping volume of the pumping component 44 , the air pressure inside the unit capsule 421 can be regulated relatively stably while the air jets are being ejected from the air jet holes 432 .

[0082] In one embodiment of the present application, Fig.10 As shown, a filling cavity 423 is provided between the polishing sleeve 431 and the unit capsule 421 .

[0083] It should be noted that there is a gap between the inner wall of the polishing sleeve 431 and the outer wall of the unit capsule 421. The space corresponding to the gap is the filling cavity 423. The volume of the filling cavity 423 is selected according to actual needs and will not be described in detail here.

[0084] Further, in one embodiment of the present application, Fig.10 As shown, the filling cavity 423 is a closed space, and the filling cavity 423 is filled with magnetic fluid 46 .

[0085] It should be noted that the inner wall of the polishing sleeve 431 may be covered with a layer of elastic sealing film (not shown in the figure), and under the restriction of the elastic sealing film and the unit capsule 421, the magnetic fluid 46 will not leak out of the filling cavity 423.

[0086] It should be noted that the end of the polishing sleeve 431 close to the mounting plate 41 is sealedly connected to the unit capsule 421, and the jet hole 432 and the outer circle position corresponding to the inner hole 422 are sealedly connected, so that the filling cavity 423 between the polishing sleeve 431 and the unit capsule 421 is a closed space.

[0087] It can be understood that after setting the filling cavity 423, relative displacement can occur between the unit capsule 421 and the polishing sleeve 431, and the deformation process of the polishing sleeve 431 can be adaptively adjusted, so that the deformation process of the polishing sleeve 431 after being pulled is more flexible and stable; the magnetic attraction of the magnetic fluid 46 enables the adjacent polishing sleeves 431 and unit capsules 421 to maintain a close fit during the polishing process, reducing excessive displacement or bending caused by vibration or friction; the magnetic fluid 46 can improve the friction state between the polishing sleeve 431 and the aluminum surface, and improve the stability of polishing.

[0088] By providing the filling cavity 423 and the magnetic fluid 46, the polishing sleeve 431 can better adjust the position and deformation degree, reducing the damage to the polishing sleeve 431 and the unit capsule 421; at the same time, the stability of polishing is improved, and the vibration and uneven friction during the polishing process are reduced.

[0089] In summary, the aluminum surface polishing equipment of the embodiment of the present application can be adaptively adjusted according to the flatness or hardness of the aluminum surface, effectively improving the polishing efficiency and polishing quality, and enhancing the flexibility and versatility of the equipment.
