Description

TECHNICAL FIELD

[0001] The application relates to the field of aluminum profile processing devices, in particular to an aluminum profile surface treatment device. BACKGROUND

[0002] With the wide application of aluminum profiles in the industrial field, especially tubular aluminum profiles as structural members or appearance members, high-quality and high-efficiency processing (such as polishing) of the inner and outer surfaces of the aluminum profiles has become a key process for improving the corrosion resistance, appearance quality and service life of the products. However, the inner cavity space of the tubular aluminum profile, especially the long pipe, is narrow and the operation accessibility is poor, and in the grinding process, the pipe is prone to bending deformation due to uneven stress. At the same time, the aluminum material is soft, the grinding heat is generated quickly, and the phenomena of tool sticking, surface scratching and "orange peel" are prone to occur. If the aluminum chips and dust generated by grinding cannot be effectively collected, the working environment and processing quality will be seriously affected.

[0003] A surface treatment device for industrial aluminum profile production and processing is disclosed in Chinese Patent No. CN223604015U, which relates to the technical field of aluminum profile production and processing, and comprises an aluminum pipe, a pipe cavity is formed in the interior of the aluminum pipe, a rotating assembly is installed at one end of the aluminum pipe, the rotating assembly comprises an end cover, a first rotary table is installed at one end of the end cover, a second rotary table is installed at the other end of the aluminum pipe, clamping jigs are installed on the outer walls of the first rotary table and the second rotary table, a drive motor is installed at one end of the first rotary table, a lifting adjusting piece for adjusting the height is installed below the drive motor, a displacement assembly for moving the clamping jig into the pipe cavity is installed below the lifting adjusting piece, and a polishing assembly is arranged above the aluminum pipe.

[0004] The above-mentioned device clamps and fixes by the clamping jig inserted into the pipe, and polishes the outer surface of the pipe by the external polishing block. This scheme simplifies the clamping and rotating process of the pipe to some extent. However, after analysis, it is found that this scheme has obvious deficiencies: first, its processing object is limited to the outer surface of the aluminum pipe, and it cannot perform synchronous or independent grinding processing on the important inner wall, so the function is single. Secondly, it relies on the clamping jig inserted into the pipe end to provide clamping force, and for long and slender pipes with large length-diameter ratio, the far end lacks effective support, and under the action of grinding force, the pipe is prone to vibration or bending deformation, affecting the processing precision and surface quality. Thirdly, the device lacks effective grinding process cleaning and debris collection mechanism, and the aluminum chips and dust directly splash, pollute the environment and may cause secondary scratches on the processed surface. Finally, the degree of automation and linkage is limited, and the pipe clamping positioning, grinding head adjustment, cleaning and other processes may still need more manual intervention, affecting the overall processing efficiency and consistency.

[0016] Compared with the prior art, the present application has the following beneficial technical effects: The present application realizes unprecedented machining precision and stability through the depth cross-linking between the outer grinding support structure, the guide column, the inner grinding support structure and the positioning adjustment structure. The positioning adjustment structure not only accurately clamps the two ends of the aluminum profile from the inside and outside through the paired positioning rollers, but also precisely engages the guide groove on the guide column through the through sleeve, thereby forcibly locking the rotation centers of the guide column, the aluminum profile and the outer grinding structure on the same axis. This linkage establishes a rigid three-dimensional positioning reference for the entire system, effectively resisting vibration and deflection of the slender tubular workpiece during high-speed rotation and feed grinding, and lays a solid geometric foundation for high-quality surface treatment. The core advantage of the device lies in the dynamic synchronous linkage of the inner and outer grinding processes. The horizontal movement of the outer grinding support structure along the guide rail and the horizontal movement of the inner grinding support structure along the guide column are accurately synchronized by the control system. At the same time, the rotation of the outer rotating sleeve and the inner rotating sleeve is also strictly synchronized. This "moving-rotating" compound motion guided by the guide column and coordinated by the double-drive structure ensures that the inner and outer grinding wheels simultaneously exert grinding forces of equal size and opposite direction on the inner and outer walls of the workpiece. This force balance greatly offsets the workpiece deformation trend caused by single-sided machining, allowing thin-walled aluminum profiles to be efficiently ground with high removal rates while achieving consistent texture on the inner and outer walls for high-quality surfaces. Further, the integration and linkage of various structures in auxiliary functions constitute an efficient and clean integrated closed-loop processing system. During grinding, the inner and outer cleaning components can be synchronized with the movement of the moving sleeve to achieve automatic cleaning before and after processing. More importantly, the aluminum slag collection cavity on the inner and outer grinding support components, the collection knife and the air outlet slot work together to scrape, cool and isolate the workpiece with the grinding wheel at the same time, and the generated debris and dust are captured in real time by the negative pressure suction port of the lower guide dust collection frame. This rapid response chain from the "processing point" to the "collection point" benefits from the precise coordination of various structures in space and action timing, not only significantly improving the cleanliness of the working environment, but also avoiding overheating and softening of aluminum materials through continuous cooling, thereby fundamentally ensuring the final processing quality and process reliability.

[0025] The inner rotating sleeve 702 moves synchronously by driving the electric wheel 70102 to move along the guide column 6, and is driven to rotate around the guide column 6 through the motor gear structure. Through the cooperation of the above structure, the plurality of grinding support structures 9 can dynamically process the inner surface of the tubular aluminum profile under the moving and rotating track.

[0026] As shown in Figure 8 The inner cleaning element 703 is provided along the outer wall of the driving ring two 70101, and each group includes a telescopic driving rod two 70301 located on the driving ring two 70101. The telescopic end of the telescopic driving rod two 70301 is provided with an inner cleaning frame 70302.

The inner cleaning frame 70302 is synchronously telescoped with the translation of the driving ring two 70103 after grinding, contacts the inner surface of the tubular aluminum profile, and removes aluminum chips and polishing paste on the surface of the aluminum pipe.

[0028] As shown in Figure 9As shown, the inner wall of the sleeve body 50102 and the outer wall of the inner rotating sleeve 702 are provided with accommodating grooves; the grinding support 9 comprises a rotating table 901 rotatingly arranged in the accommodating groove and driven by a motor; the rotating table 901 is provided with a mounting seat 902; the rotating table 901 and the mounting seat 902 are provided with aluminum slag collecting cavities 907 and air outlet grooves 908 for installing aluminum slag collecting structures; the aluminum slag collecting cavities 907 penetrate through the rotating table 901 and the mounting seat 902 and are open at the side of the mounting seat 902; the grinding support wheel 903 is lifted and rotated on the opening of the aluminum slag collecting cavity 907 through a lifting head 904; the bottom of the aluminum slag collecting cavity 907 is provided with a plurality of groups of retractable aluminum slag collecting knives 906 along the rotating direction of the grinding support wheel 903; the air outlet groove 908 is located outside the grinding support wheel 903 and is connected with the aluminum slag collecting cavity 907, and the air outlet groove 908 is provided with an air outlet head 905 to blow air towards the grinding support end of the grinding support wheel 903, so as to form a wind wall to prevent the aluminum slag from overflowing and to blow air to remove the aluminum slag adhered to the grinding support wheel 903 and cool the grinding support wheel 903.

[0029] The lifting head 904 drives the grinding support wheel 903 to rotate on one side through a motor, so as to achieve the purpose of grinding or supporting. The lifting head 904 moves up and down on the other side through cooperation with the track in the aluminum slag collecting cavity 907, so as to adjust the distance between the grinding support wheel 903 and the tubular aluminum profile. The aluminum slag collecting knives 906 are controlled to stretch and retract through a cylinder, abut against the grinding support end of the grinding support wheel 903, and scrape off the adhered aluminum slag.

[0030] Aluminum is soft and has a low melting point and is easy to generate heat by friction. Overheating can cause the surface of the aluminum material to soften and then deform or stick to the polishing wheel, resulting in deeper scratches and "orange peel" phenomenon.

[0031] The present application sets that the moving tracks of the plurality of groups of grinding support wheels 903 inside and outside correspond to each other, synchronously contact the aluminum profile, and perform synchronous grinding (grinding of both the inner and outer surfaces) or one-side grinding (grinding of the inner surface and supporting of the outer surface or supporting of the inner surface and grinding of the outer surface) of the inner and outer surfaces. On the one hand, efficient and comprehensive grinding is achieved, and on the other hand, the inner and outer supports are provided to reduce deformation caused by one-side stress.

[0032] The present application sets that the aluminum slag collecting knives 906 scrape off the aluminum slag adhered to the grinding support wheel 903 entering the aluminum slag collecting cavity 907. The air outlet head 905 synchronously blows air to the grinding support wheel 903, which not only prevents the aluminum slag from overflowing, but also achieves the purpose of cleaning and cooling the grinding support wheel 903.

[0033] As Figure 10As shown, the guiding dust collecting frame 3 comprises a frame body 301 on the base 1; two ends of the frame body 301 are provided with moving grooves 302; the periphery of the moving grooves 302 is provided with a plurality of dust collecting heads 303; the dust collecting heads 303 form a negative pressure environment by connecting a negative pressure device, so as to collect the grinding dust.

[0034] As shown in the figure, Figure 11 The positioning adjusting structure 8 is provided with two groups, each of which comprises a telescopic driving rod two 801 moving horizontally along the moving groove 302; the positioning adjusting piece 802 comprises a fixing ring 80201 on the telescopic end of the telescopic driving rod two 801; the side of the fixing ring 80201 facing the outer grinding support structure 5 is provided with a through sleeve 80203 coaxial with it; the through sleeve 80203 and the fixing ring 80201 are used for the penetration and fixation of the guide column 6; the inner wall of the through sleeve 80203 is provided with a protruding tooth matched with the guide groove 601, and the outer wall is provided with a positioning frame 80204; the positioning frame 80204 is provided with a positioning track; two groups of positioning blocks are slidingly arranged on the positioning track; the positioning rollers 80205 are arranged in pairs, one-to-one corresponding and rotationally connected with the positioning blocks.

[0035] It should be further explained that the positioning frame 80204 is arranged in a cross shape.

[0036] It should be further explained that the outer part of the positioning roller 80205 is provided with a grinding layer.

[0037] It should be further explained that the inner wall of the fixing ring 80201 is provided with an electrically controlled telescopic clamping block 80202 matched with the guide groove 601.

[0038] When installing, the positioning adjustment member 802 on one side is lifted to be coaxial with the through sleeve 80203 and the outer rotating sleeve 502. The tubular aluminum profile is first inserted through the outer rotating sleeve 502, and the pipe opening on one side is opposite to the corresponding side positioning frame 80204. The paired positioning rollers 80205, one set of which is located inside the pipe opening and the other set of which is located outside the pipe opening, are fixed to one end of the tubular aluminum profile by moving the two sets of positioning rollers 80205 relative to each other. Then the guide column 6 is inserted into the tubular aluminum profile from the other end until the end of the guide column 6 enters the through sleeve 80203 and the fixing ring 80201. The positioning adjustment member 802 on the other side is then lifted and translated to fix the other end of the tubular aluminum profile in the same way. Since the positioning adjustment member 802 can slide horizontally, the clamping distance of the paired positioning rollers 80205 can be adjusted, so that tubular aluminum profiles of different lengths and thicknesses can be fixed. Finally, the clamping blocks 80202 on both sides are extended to fix the guide column 6 on the corresponding side again. At this time, the pipe opening of the aluminum profile is clamped by the paired positioning rollers 80205 on the corresponding side. The paired positioning rollers 80205 can rotate to drive the tubular aluminum profile to rotate synchronously to cooperate with the grinding support wheel 903 for grinding. Alternatively, the grinding support wheel 903 can be pressed against the inner and outer walls of the tubular aluminum profile, while the sleeve body 50102 and the inner rotating sleeve 702 rotate to drive the aluminum profile to rotate. The positioning rollers 80205 grind the pipe opening of the aluminum profile.

[0040] Since the tubular aluminum profile and the guide column 6 are both long, during installation, the tubular aluminum profile and the guide column 6 can be placed on the lifting platform 202 on one side in sequence for easy operation. Here, the lifting platform 202 should be opposite to the first group of positions that are lifted. That is, the positioning adjustment member 802 on one side is lifted, and the lifting platform 202 on the other side is lifted. The tubular aluminum profile is first placed on the lifted lifting platform 202 and is inserted through the outer grinding support structure 5 by pushing forward until one end is fixed by the lifted positioning adjustment member 802. The positioning adjustment member 802 on the other side is lifted to fix the other end of the tubular aluminum profile. Then the guide column 6 with the inner grinding support structure 7 is placed on the lifting platform 202 and is pushed forward until the inner grinding support structure 7 is opposite to the outer grinding support structure 5, and the two ends of the guide column 6 are inserted through and fixed in the fixing ring 80201 on the corresponding side.
