Description

Technical Field

[0001] The present invention relates to the technical field of aluminum surface treatment, and specifically to a polishing device for repairing the end faces of aluminum materials. Background Art

[0002] Aluminum materials are metal materials mainly composed of aluminum, which are made through processes such as rolling, extrusion, or casting, and are widely used in fields such as construction, transportation, electronics, and aerospace. During the production process of aluminum materials, irregular protrusions such as burrs and flash are often generated on the outer walls and cut end faces due to machining. These defects not only affect the appearance quality and dimensional accuracy of the workpieces, but may also reduce the assembly performance, and even cause stress concentration, resulting in a decrease in the fatigue life of the components. Therefore, polishing equipment is required to polish and repair the burrs, flash, and other defective parts on the surface of aluminum materials.

[0003] During the use of existing polishing devices, deficiencies have gradually emerged, mainly manifested in the following aspects: First, the discrete processing mode leads to low polishing efficiency and affects processing accuracy. Specifically, existing polishing equipment usually adopts a step-by-step processing method during the repair of aluminum materials. First, the cut end face of the aluminum material is polished, then the side wall of the aluminum material is polished, and finally the R corner part of the aluminum material is processed separately. Since there are significant differences in the structural form and spatial position between the end face, side wall, and R corner, each process requires matching special clamping fixtures and polishing tools. Therefore, during the processing, the fixtures and equipment must be frequently replaced. This discrete operation mode leads to low efficiency in the connection of processes, seriously affecting the overall polishing efficiency, and multiple repeated positioning will also cause error accumulation, affecting processing accuracy.

[0004] Second, the polishing consistency of the R corner part of aluminum materials is poor. Specifically, during the polishing process of aluminum materials, due to the curved surface characteristics of the R corner part, manual operation of an electric sander is usually relied on for polishing. During manual polishing, the differences in the techniques of operators and fatigue factors are likely to lead to instability in the polishing pressure, angle, and trajectory, making it difficult to maintain consistency in the surface roughness and chamfer size of the R corner part.

[0005] Third, the degree of automation is low. Specifically, the polishing of the outer wall of aluminum materials can be processed by automated grinding equipment, but the end face and R corner parts still rely on manual grinding due to their complex geometric shapes and limited processing space. This mixed processing mode results in a low degree of automation in the overall polishing process, affecting the polishing efficiency of aluminum materials.

[0006] In summary, it is obvious that there are inconveniences and defects in the actual use of the existing technology, so it is necessary to make improvements. Summary of the Invention

[0007] Aiming at the defects in the prior art, the technical problem to be solved by the present invention is to provide a polishing device for repairing the end face of aluminum materials.

[0018] Compared with the prior art, the beneficial effects of the present invention are: 1. When polishing and repairing aluminum materials, first place the aluminum materials between the baffles, and move the two push plates towards each other until both push plates are in contact with the cutting end face of the aluminum materials. Thus, the preliminary centering adjustment of the aluminum materials is completed, preventing large deviations in the clamping position of the aluminum materials from affecting the subsequent polishing process. After that, rotate the rotating plate so that the feeding carrier plate faces downward, and the multi-stage telescopic cylinder drives the feeding carrier plate to descend to a preset position. The pneumatic telescopic cylinder drives the feeding clamping plates to slide towards each other and clamp the aluminum materials. Then, the feeding carrier plate resets, and the rotating plate rotates 90°. The multi-stage telescopic cylinder pushes the clamped aluminum materials between the two grinding wheels. The driving telescopic cylinder drives the grinding wheels to move until they are in contact with the cutting end face of the aluminum materials. The grinding motor drives the grinding wheels to rotate, thereby polishing the cutting end face of the aluminum materials. The multi-stage telescopic cylinder drives the clamped aluminum materials to move horizontally, thereby completely polishing the cutting end face of the aluminum materials. After the cutting end face of the aluminum materials is polished, the grinding wheels reset. The drive shaft drives the rotating plate to rotate 180°. The adjusting telescopic cylinder drives the adjusting plate to move horizontally. The clamping plate is inserted into the aluminum material and contacts the inner wall of the aluminum material, thereby clamping the aluminum material until the top plate abuts against the end face of the aluminum material. After that, the feeding carrier plate and the rotating plate reset successively. The lifting plate descends until the sand belt contacts the top surface of the aluminum material. The built-in telescopic cylinder drives the lifting U-shaped plate to descend until the lifting wheel descends into the aluminum material. At this time, the lifting wheel contacts the sand belt. At the same time, driven by the insertion rod, the swinging plate drives the clamping wheel to swing until the sand belt contacts the side wall of the aluminum material. The driving wheel drives the sand belt to rotate, thereby polishing the side wall and the R corner part of the aluminum material at the same time.

When the polishing device polishes the R corner part of the aluminum material, the polishing pressure, angle, and trajectory are stable. Therefore, the polishing effect on the R corner part of the aluminum material has high consistency; 3. During the process of centralized polishing of the side walls and the R corner parts of the aluminum material, repeat the above process of feeding the aluminum material and polishing the cutting end face of the aluminum material to polish the cutting end face of the aluminum material to be processed, realizing the function of polishing the cutting end face of the aluminum material to be processed while centralizedly polishing the side walls and the R corner parts of the aluminum material, and further improving the polishing efficiency of the aluminum material; 4. During the process of concentrating on polishing the side wall and R corner of the aluminum material, after the cutting end face of the aluminum material to be processed is polished, the grinding wheel and the feeding carrier plate are reset successively, and the rotating plate rotates 180°. At this time, the discharging carrier plate is on the inner side. After the side wall and R corner of the aluminum material are polished, the rotating plate rotates 180°. The discharging carrier plate approaches the polished aluminum material. The electric control telescopic cylinder drives the discharging clamping plates to slide towards each other and clamp the polished aluminum material. Then, the top plate and the discharging carrier plate are reset successively, and the rotating plate rotates 180°. The polished aluminum material is sent to the outside of the operating table by the discharging clamping plates, and the aluminum material with the cutting end face polished is sent to the inside. The clamping plate and the top plate clamp the aluminum material sent to the inside and polish the side wall and R corner of the aluminum material. By circulating the above process, the aluminum material can be polished continuously. This polishing device has a high degree of automation. The processes of concentrating on polishing the side wall and R corner of the aluminum material, polishing the cutting end face of the aluminum material, and loading and unloading the aluminum material are all automated processes, which further improves the polishing efficiency of the aluminum material.

The multi-stage telescopic cylinder 54 drives the clamped aluminum material 8 to move horizontally to completely polish the cutting end face of the aluminum material 8. After the cutting end face of the aluminum material 8 is polished, the grinding wheels 41 reset. The driving shaft 7 drives the rotating plate 14 to rotate 180°. The adjusting telescopic cylinder 43 drives the adjusting plate 44 to move horizontally. The clamping plate 46 is inserted into the aluminum material 8 and contacts the inner wall of the aluminum material 8 to clamp the aluminum material 8 until the top plate 45 abuts against the end face of the aluminum material 8. After that, the loading and bearing plate 55 and the rotating plate 14 reset successively. The lifting plate 11 descends until the sand belt 34 contacts the top surface of the aluminum material 8. The built-in telescopic cylinder 37 drives the lifting U-shaped plate 35 to descend until the lifting wheel 23 descends into the aluminum material 8.

At the same time, driven by the insertion rod 26, the swing plate 25 drives the clamping wheel 24 to swing until the sand belt 34 contacts the side wall of the aluminum material 8. The driving wheel 31 drives the sand belt 34 to rotate to polish the side wall and the R corner part of the aluminum material 8 simultaneously. The driving motor 2 drives the sliding plate 10 to slide horizontally to completely polish the side wall and the R corner of one side of the aluminum material 8. The orientation adjustment motor 42 can rotate and adjust the clamped aluminum material 8, so that the entire side wall and the R corner of the aluminum material 8 can be completely polished. This device can perform centralized polishing treatment on the side wall and the R corner part of the aluminum material 8, can polish the side wall and the R corner part of the aluminum material 8 at the same time, greatly improves the polishing efficiency, reduces the replacement frequency of the fixture, and ensures the processing accuracy; When the polishing device polishes the R corner part of the aluminum material 8, the polishing pressure, angle and trajectory are stable. Therefore, the polishing effect on the R corner part of the aluminum material 8 has high consistency; During the process of centralized polishing of the side wall and the R corner part of the aluminum material 8, repeat the above process of loading the aluminum material 8 and polishing the cutting end face of the aluminum material 8 to polish the cutting end face of the aluminum material 8 to be processed. The function of polishing the cutting end face of the aluminum material 8 to be processed while centrally polishing the side wall and the R corner part of the aluminum material 8 is realized, further improving the polishing efficiency of the aluminum material 8; During the process of concentrating on polishing the side wall and R corner of the aluminum material 8, and after the cutting end face of the aluminum material 8 to be processed is polished, the grinding wheel 41 and the loading carrier plate 55 are reset successively, and the rotating plate 17 rotates 180°. At this time, the unloading carrier plate 53 is on the inner side. After the side wall and R corner of the aluminum material 8 are polished, the rotating plate 14 rotates 180°. The unloading carrier plate 53 approaches the polished aluminum material 8. The electric control telescopic cylinder 52 drives the unloading clamping plates 51 to slide towards each other and clamp the polished aluminum material 8.
