[0023] To make the purpose, technical solutions, and advantages of the present invention more clearly apparent, a detailed description is provided below in conjunction with the accompanying drawings and specific embodiments. The following description sets forth many specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar improvements without violating the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0024] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only implementation methods.

[0025] Example 1: Please refer to Figures 1 to 3 This embodiment discloses a metal sanding machine for aluminum plate painting, which is intended to realize the automated grinding processing of aluminum plate painting, improve production efficiency, and ensure the consistency of product quality.

[0026] The aluminum plate painting metal sanding machine specifically comprises a frame 1 formed by welding aluminum alloy profiles and panels, and the frame 1 mainly plays a bearing and supporting role.

[0027] A horizontal placement table 2 is provided on the frame 1. The top of the placement table 2 is used to place the aluminum plate painting substrate to be processed. When in use, the aluminum plate painting substrate is placed on the placement table 2 at the threshold position to keep it in a horizontal posture and wait for polishing and drawing patterns.

[0028] Furthermore, the top of the storage table 2 is provided with a detachable wooden board, and the top surface of the wooden board is provided with an anti-slip structure to prevent the aluminum plate painting substrate from sliding during the processing. The selected wooden board material can firstly have a certain compressive toughness to ensure the structural stability of the aluminum plate painting during the polishing process. Secondly, the cost of wood is relatively low, which is conducive to reducing operating costs. Moreover, the wooden board is easy to disassemble, replace, and process the levelness, which is conducive to improving processing quality and maintenance convenience.

[0029] The storage platform 2 is provided with bases 3 on either side. Bases 3 are also made of aluminum alloy profiles and panels, serving as an elevated structure. A crossbeam 4 is installed between the tops of the two bases 3, oriented left and right. A forward and backward displacement mechanism is provided between the crossbeam 4 and the base 3. This mechanism utilizes a linear track slide system oriented forward and backward, which can autonomously drive the entire crossbeam 4 to slide forward and backward according to instructions. This is prior art, and its specific structure and operating principle will not be elaborated here. Those skilled in the art can select and implement a model from existing technologies based on actual operational conditions.

[0030] A lifting frame 5 is provided on the beam 4. The lifting frame 5 is an aluminum alloy frame structure. A left-right displacement mechanism is provided between one side of the lifting frame 5 and the side wall of the beam 4. The left-right displacement mechanism specifically adopts a motor screw transmission assembly, which can drive the lifting frame 5 to slide left and right along the beam 4 as a whole according to instructions. It is a prior art, and its specific structure and working principle are not described here in detail. Those skilled in the art can select and implement it from the prior art according to actual operating conditions.

[0031] A sanding module for grinding and polishing operations is provided at the bottom of the lifting frame 5. An up and down displacement mechanism is provided between the lifting frame 5 and the sanding module. The up and down displacement mechanism specifically adopts a motor screw transmission assembly, which can drive the sanding module to move up and down relative to the lifting frame 5 according to instructions. It is an existing technology, and its specific structure and working principle are not described here. Those skilled in the art can select and implement it from the existing technology according to actual operating conditions.

[0032] The sanding module includes a rotary drive member, specifically a servo motor, which is fixed on a base plate, which is fixedly connected to the output end of the up-and-down displacement mechanism. The output end of the rotary drive member is located at the bottom and is connected to a tooling module 6, which is located below the lifting frame 5. The bottom of the tooling module 6 is detachably connected to six strip-shaped sanding members 7. The sanding members 7 are made of ordinary abrasives bonded into a strip-shaped block structure by a binder and used as a grinding tool. The bottom of the sanding member 7 is the grinding and polishing operation end. The frame 1 is provided with a control module for electrically connecting and controlling the various moving parts. The control module specifically adopts a PLC control circuit board, which is a prior art. Its specific structure and working principle will not be repeated here. Those skilled in the art can select and implement it from the prior art according to actual operation conditions.

[0033] Specific, combined Figure 2 and Figure 3 As shown, the tooling module 6 includes a mounting base 61 with a disc structure. A connecting block 62 for connecting to the output end (rotating shaft) of the rotating drive member is provided at the center of the top of the mounting base 61. In this embodiment, the connecting block 62 is fixed to the rotating shaft by welding. Six mounting slots 63 are provided at the bottom of the mounting base 61. The six mounting slots 63 are arranged symmetrically on the bottom surface of the mounting base 61, and the lengths of the six mounting slots 63 are consistent. Two spaced-apart fastening holes 64 are provided at the top of each mounting slot 63. The fastening holes 64 extend longitudinally through the mounting base 61. The inner contour of the mounting slot 63 is adapted to the outer contour of the sanding element 7, and the depth of the mounting slot 63 is less than the thickness of the sanding machine, so that the bottom of the sanding element 7 can extend to the outside after being installed in the mounting slot 63.

[0034] A connecting hole 71 adapted to the fastening hole 64 is provided on the top of the sanding piece 7 . The connecting hole 71 is a threaded hole structure for fitting a bolt in the fastening hole 64 to form a connecting structure between the sanding piece 7 and the mounting seat 61 .

[0035] The rotary drive element drives the mounting base 61 and sanding element 7 to rotate at high speed. The working end at the bottom of the sanding element 7 grinds and polishes the workpiece in contact during high-speed movement. In practice, the control module generates a specific operating path and operating parameters for each component based on a preset pattern. The sanding module, working in conjunction with the three-dimensional displacement mechanism, enables path movement and height control. During this process, the sanding element 7 simultaneously polishes the surface of the aluminum plate painting substrate to achieve the desired effect, achieving automated grinding of the aluminum plate painting and significantly improving production efficiency.

[0036] In order to prevent fine chips generated by grinding from flying out, a protective cover 11 is provided on the top of the frame 1. The protective cover 11 has an opening on the front of the frame 1, and the other three sides form a protective barrier structure.

[0037] Example 2: Based on Example 1, Figure 4 As shown, in this embodiment, the grinding and polishing working end at the bottom of the sanding piece 7 is provided with spaced flanges 72. The existence of the flanges 72 makes the structure of the working end of the sanding piece 7 more diverse and varied, with concave and convex texture changes, which is conducive to increasing the structural richness of the grinding effect and performing structural hierarchical differentiation of the working end of the sanding piece 7. The flanges 72 will wear after long-term operation, and the wear will make its thickness thinner, so that the working end originally located at a low position can continue to provide a relatively rough grinding surface. Although the grinding effect changes appropriately, the service life of the grinding tool can be extended.

[0038] Example 3: Based on Example 1, Figure 5 In this embodiment, a plurality of short strip-shaped sanding pieces 7 are used, and adjacent sanding pieces 7 are staggered in the radial direction of the mounting seat 61. Under high-speed rotation, a complete sanding working surface can be formed, thereby utilizing lightweight and miniaturized sanding pieces 7 to achieve the same processing effect, which is conducive to the subsequent convenient replacement of the sanding pieces 7 and low-cost maintenance according to the actual degree of wear.

[0039] Example 4: Based on Example 1, combined Figure 6 As shown, in this embodiment, a pad 8 made of elastic material (rubber) is provided between the sanding piece 7 and the mounting groove 63. Its function is to provide a certain degree of elastic support, so that the connection between the sanding piece 7 and the mounting seat 61 is tighter and not easy to fall off. In addition, the sanding piece 7 has a certain degree of elastic buffering ability during the sanding process, which is beneficial to avoid excessive rigidity and extrusion of the workpiece.

[0040] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some of the technical features thereof can be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
