Description

Technical Field

[0001] This utility model relates to the field of polishing device technology, and in particular to an aluminum profile surface polishing device. Background Technology

[0002] Aluminum profiles are alloy materials with aluminum as the main component. Aluminum rods are melted and extruded to obtain aluminum materials with different cross-sectional shapes. However, the mechanical properties and application fields of the industrial aluminum profiles produced vary depending on the proportion of alloys added. Generally speaking, industrial aluminum profiles refer to all aluminum profiles except those used for building doors and windows, curtain walls, interior and exterior decoration, and building structures. Polishing refers to a processing method that uses mechanical, chemical, or electrochemical actions to reduce the surface roughness of a workpiece to obtain a bright and smooth surface. It involves using polishing tools and abrasive particles or other polishing media to refine the surface of the workpiece. Polishing does not improve the dimensional or geometric accuracy of the workpiece, but rather aims to obtain a smooth surface or mirror gloss. Sometimes it is also used to eliminate gloss (matte finish). Polishing wheels are typically used as polishing tools.

[0003] Existing aluminum profiles are typically square in shape. When using existing polishing machines, the top and sides can be polished simultaneously, but the bottom of the aluminum profile cannot be polished at the same time as the other sides. This results in the bottom of the aluminum profile needing to be polished separately after the top and sides are polished, leading to low polishing efficiency.

[0004] Therefore, it is necessary to provide an aluminum profile surface polishing device to solve the above-mentioned technical problems. Utility Model Content

The lower moving lifting mechanism 35 is connected to the top of the protective cover 4 with openings on both sides. The bottom of the protective cover 4 is installed on the top of the processing table 1. The left polishing wheel 11 and the right polishing wheel 18 are respectively provided above the processing table 1 on both sides of the lower polishing wheel 29. The left polishing wheel 11 and the right polishing wheel 18 are movably connected to the left mounting plate 9 and the right mounting plate 16 respectively. The bottom of the left mounting plate 9 and the right mounting plate 16 are respectively connected to the drive ends of the left polishing motor 8 and the right polishing motor 15. The bottom of the left polishing motor 8 is connected to the left slide rail 7 through a slider. The bottom of the right polishing motor 15 is connected to the right slide rail 14 through a slider. The left slide rail 7 and the right slide rail 14 are respectively installed at both ends of the top of the processing table 1.

[0038] In the embodiments of this utility model, reference is made to Figure 7 , Figure 8 As shown, the first moving mechanism 2 and the second moving mechanism 3 have the same structure. The first moving mechanism 2 includes an upper rotating wheel 106 and a lower rotating wheel 101. The lower rotating wheel 101 is rotatably connected to the inner side of the lower connecting frame 105 through a lower rotating shaft 102. One end of the lower rotating shaft 102 passes through the side of the lower connecting frame 105 and is connected to the drive end of the lower motor 103. The bottom of the lower connecting frame 105 is connected to the top of the processing table 1. The lower motor 103 is mounted on a motor plate 104 connected to the outer side of the lower connecting frame 105. The upper rotating wheel 106 is rotatably connected to the inner side of the upper connecting frame 108 through an upper rotating shaft 109. The top of the upper connecting frame 108 is connected to the top of the protective cover 4 through an adjusting cylinder 107.

[0039] In the embodiments of this utility model, reference is made to Figure 6 As shown, the lifting mechanism 35 includes a lifting plate 37, the top of which is connected to the telescopic end of the lifting cylinder 38, and the top of the lifting cylinder 38 is connected to the top of the protective cover 4.

[0040] In the embodiments of this utility model, reference is made to Figure 1 As shown, the height of the top of the lower polishing wheel 29 is the same as the height of the top of the lower rotating wheel 101.

[0041] It should be noted that the left slide rail 7 and the right slide rail 14 are existing electric slide rails;

[0042] In use, the bottom ends of the square aluminum profile can be placed on the lower rotating wheels of the first moving mechanism 2 and the second moving mechanism 3, respectively. Driven by the lower motor 103 on the first moving mechanism 2 and the second moving mechanism 3, the two lower rotating wheels can be rotated, causing the square aluminum profile to move forward. Before moving, the left polishing wheel 11 and the right polishing wheel 18 need to be moved along the left slide rail 7 and the right slide rail 14 to move the two sides of the aluminum profile until the sides of the left polishing wheel 11 and the right polishing wheel 18 are in contact with the sides of the aluminum profile. When selecting the left polishing wheel 11 and the right polishing wheel 18, the thickness of the selected left polishing wheel 11 and the right polishing wheel 18 should be consistent with the height of the side of the aluminum profile. The lifting slide rail can be controlled to... Driven by the lifting cylinder 38, the lifting plate 37 moves downward, which in turn moves the upper polishing wheel 33 downward to contact the top of the aluminum profile. Since the top of the lower polishing wheel 29 is at the same height as the top of the lower rotating wheel 101, the top of the lower polishing wheel 29 contacts the bottom of the aluminum profile. During polishing, the polishing wheel rotates due to the rotation of the corresponding polishing motor, which can polish all four sides of the square aluminum profile at the same time. This solves the problem that existing polishing machines can polish the top and sides simultaneously, but the bottom of the aluminum profile cannot be polished simultaneously with other sides, resulting in low polishing efficiency because the bottom of the aluminum profile needs to be polished separately after the top and sides are polished.

[0043] In the embodiments of this utility model, reference is made to Figure 5 , Figure 6 As shown, an upper mounting shaft 32 is mounted on the bottom of the upper mounting plate 31.

Furthermore, the upper polishing wheel 33 and the lower polishing wheel 29 of appropriate size can be selected according to the requirements. In addition, by setting an upper limit ring 34 and a lower limit ring 36 made of magnetic material, it is convenient to connect with the upper polishing wheel 33 and the lower polishing wheel 29 through magnetism, thereby improving the stability of the connection.

[0047] It should be noted that by setting a left polishing wheel 11 that can be slidably connected to the left mounting shaft 10 and fixed by the left limit bolt 12, and by setting a right polishing wheel 18 that can be slidably connected to the right mounting shaft 17 and fixed by the right limit bolt 19, it is convenient to disassemble the left polishing wheel 11 and the right polishing wheel 18 from the corresponding mounting shaft, thereby improving the efficiency of replacing the polishing wheel and the right polishing wheel 18. Furthermore, the appropriate size of the polishing wheel and the right polishing wheel 18 can be selected according to the requirements, thereby improving the applicability of the equipment.

[0052] It should be noted that by setting up the observation window 5, it is convenient to observe the inside of the protective cover 4 from the outside, so that abnormalities can be detected and dealt with immediately.

[0053] The working principle of the aluminum profile surface polishing equipment provided by this utility model is as follows:

[0054] Driven by the lower motors 103 on the first moving mechanism 2 and the second moving mechanism 3, the two lower rotating wheels can be rotated, causing the square aluminum profile to move forward. During polishing, the corresponding polishing motor rotates, driving the polishing wheel to rotate, which can polish all four sides of the square aluminum profile at the same time. This solves the problem that existing polishing machines can polish the top and sides simultaneously, but the bottom of the aluminum profile cannot be polished simultaneously with other sides, resulting in low polishing efficiency because the bottom of the aluminum profile needs to be polished separately after the top and sides are polished.
