Description

Technical Field

[0001] The utility model belongs to the technical field of corner cleaning machines, and particularly relates to a corner cleaning machine. Background Art

[0002] The most challenging job in the decoration, furnishing, and renovation industries is corner and frame assembly. During construction, as long as the corners are properly assembled, the pass rate for construction according to the drawings reaches 80%. Project acceptance often focuses on the corners, and traditionally, corner assembly is performed manually. This requires a very high level of skill from the artisan. Even so, scratches, bruises, and discoloration still occur frequently, and marking complex decorative pieces is challenging. Some jobs simply cannot be accurately marked manually, requiring repeated grinding and trial assembly during processing. This not only reduces efficiency but also fails to achieve the desired effect.

[0003] Laser cutting and mechanical cutting, which are popular on the market, are good options, but they still cannot meet the needs. The reason is that laser can only cut flat and simple surfaces, and the requirements for tooling are also very high. Moreover, it can only cut in batches. In decoration projects, there are many changes, and batches of workpieces are small. Many workpieces require secondary processing after laser cutting, such as extrusion and bending, which will have errors and require manual grinding, which is costly. Mechanical cutting is only suitable for workpieces with simple shapes. It is very difficult to clamp workpieces with complex shapes such as extrusion and bending. It cannot guarantee stable clamping, and the accident rate during processing is particularly high. Some workpieces cannot be clamped or cut at all.

[0004] In order to solve the above problems, this application proposes a corner cleaning machine. Utility Model Content

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] like Figure 1 As shown;

[0028] A corner cleaning machine comprises a support frame 1, a workbench 2 is mounted on the top of the support frame 1, and is characterized in that a decorative part precision grinding mechanism 3 is provided on the top of the workbench 2.

[0029] In this embodiment, under normal circumstances, the popular laser cutting and mechanical cutting methods on the market are good choices, but they still cannot meet the needs. The reason is that laser can only cut flat surfaces and simple shapes, and the requirements for tooling are also very high. Moreover, it can only cut in batches. In decoration projects, there are many changes, and batch workpieces are small. Many workpieces require secondary processing after laser cutting, such as extrusion and bending, which will result in errors and require manual grinding, which is costly. Mechanical cutting is only suitable for workpieces with simple shapes. It is very difficult to clamp workpieces with complex shapes such as extrusion and bending, and it cannot ensure stable clamping. The accident rate during processing is particularly high, and some workpieces cannot be clamped or cut at all. Therefore, by adding a decorative part precision grinding mechanism 3, the rough-machined surface at the corner of the decorative part can be conveniently ground, and the grinding angle can be easily adjusted.

[0030] like Figure 1-Figure 5 As shown;

[0031] By adding a precision grinding mechanism 3 to existing corner cleaning machines, the decorative parts can be precisely ground. This solves the problem of high variation and small batch sizes in decorative projects. Many workpieces require secondary processing after laser cutting, such as extrusion and bending, which can introduce errors and require manual grinding, which is costly. Mechanical cutting is only suitable for simple workpieces. Clamping complex workpieces, such as those produced by extrusion and bending, is difficult and cannot be guaranteed to be stable. This leads to a high incidence of accidents during processing, and some workpieces cannot be clamped or cut at all.

[0032] More specifically:

[0033] In combination with the above content, in order to conveniently grind the rough-machined surface at the corner of the decorative part, and the grinding angle can be conveniently adjusted, a decorative part precision grinding mechanism 3 is provided on the top of the workbench 2. The decorative part precision grinding mechanism 3 includes a support platform 31, a drive motor 32, a drive wheel 33, a support side plate 34, a rotating shaft 35, a grinding belt 36, a drive belt 37, a reciprocating component 38 and an adjustment component 39. The support platform 31 is fixedly connected to one side of the top of the support frame 1, and the drive motor 32 is installed on the support platform 3 1, and the output end of the drive motor 32 is fixedly connected to the drive wheel 33, the support side plates 34 are symmetrically fixedly connected to the inner wall of the support frame 1, the rotating shaft 35 is symmetrically rotatably connected to both sides of the inner wall of the support side plates 34, the frosting belt 36 is sleeved on the rotating shaft 35, one section of which passes through one side of the support side plate 34, one end of the rotating shaft 35 and the drive wheel 33 are sleeved with a drive belt 37, a reciprocating assembly 38 is arranged on the top of the workbench 2, and an adjusting assembly 39 is arranged on the reciprocating assembly 38.
