Description

Technical Field

[0001] The invention relates to the technical field of aluminum material surface treatment, in particular to a polishing device for repairing the end face of an aluminum material. Background Art

[0002] Aluminum, a metal material primarily composed of aluminum, is manufactured through processes such as rolling, extrusion, or casting. It is widely used in fields such as construction, transportation, electronics, and aerospace. During the aluminum production process, machining often produces irregular protrusions such as burrs and flash on the outer wall and cut end faces. These defects not only affect the appearance quality and dimensional accuracy of the workpiece, but can also reduce assembly performance and even cause stress concentration, resulting in a reduction in component fatigue life. Therefore, polishing equipment is required to repair burrs, flash, and other defects on the aluminum surface.

[0003] The existing polishing device gradually exposed its shortcomings during use, mainly in the following aspects:

[0004] First, the discrete processing mode leads to low polishing efficiency and affects the processing accuracy. Specifically, the existing polishing equipment usually adopts a step-by-step processing method in the aluminum repair process. First, the cut end face of the aluminum is polished, then the side wall of the aluminum is polished, and finally the R corner of the aluminum is processed separately. Due to the significant differences in structural form and spatial position of the end face, side wall and R corner, each process requires matching special clamping tooling and polishing tools. Therefore, the fixture and equipment must be frequently replaced during the processing. This discrete operation mode leads to low process connection efficiency, seriously affecting the overall polishing efficiency. In addition, repeated positioning will lead to accumulated errors, affecting the processing accuracy.

[0005] Second, the polishing consistency of the R-corner of aluminum is poor. Specifically, during the polishing process of aluminum, the R-corner part is usually polished by a manually operated electric sanding machine due to its curved surface characteristics. The difference in operator techniques and fatigue factors during manual polishing can easily lead to instability in polishing pressure, angle and trajectory, making it difficult to maintain consistency in the surface roughness and chamfer size of the R-corner part.

[0006] Third, the degree of automation is low. Specifically, the polishing of the outer wall of aluminum can be handled by automated polishing equipment, but the end face and R corner parts still rely on manual polishing due to their complex geometric shapes and limited processing space. This mixed processing mode leads to a low degree of automation in the overall polishing process, affecting the polishing efficiency of aluminum.

[0007] In summary, the existing technology has obvious inconveniences and defects in actual use, so it is necessary to improve it. Summary of the Invention

[0008] In response to the defects in the prior art, the technical problem to be solved by the present invention is to provide a polishing device for aluminum end face repair, which can perform centralized polishing treatment on the side walls and R-corner parts of the aluminum material. The side walls and R-corner parts of the aluminum material can be polished at the same time, and the cut end faces of the aluminum material to be processed can be polished during the centralized polishing process, thereby greatly improving the polishing efficiency, reducing the frequency of fixture replacement, and ensuring processing accuracy.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. When polishing and repairing aluminum, first place the aluminum between the baffles, and the two push plates move toward each other until both push plates are in contact with the cut end face of the aluminum. At this point, the initial centering adjustment of the aluminum is completed to prevent the large deviation of the clamping position of the aluminum from affecting the subsequent polishing and grinding process. Then the rotating plate rotates until the loading carrier plate faces downward, and the multi-stage telescopic cylinder drives the loading carrier plate to descend to the preset position. The pneumatic telescopic cylinder drives the loading clamps to slide toward each other and clamp the aluminum, and then the loading carrier plate is reset. The rotating plate rotates 90°, and the multi-stage telescopic cylinder pushes the clamped aluminum between the two grinding wheels. The driving telescopic cylinder drives the grinding wheel to move to contact the cut end face of the aluminum. The grinding motor drives the grinding wheel to rotate and then polish the cut end face of the aluminum. The multi-stage telescopic cylinder drives the clamped aluminum to move horizontally to completely polish the cut end face of the aluminum. After the polishing of the cut end face of the aluminum is completed, the grinding wheel is reset, the drive shaft drives the rotating plate to rotate 180°, and the adjusting telescopic cylinder drives the adjusting plate to move horizontally. The clamping plate is inserted to The aluminum material is inside and contacts the inner wall of the aluminum material, and then the aluminum material is clamped until the top plate and the end face of the aluminum material are butted, and then the loading bearing plate and the rotating plate are reset in succession, and the lifting plate drops down until the sanding belt contacts the top surface of the aluminum material, and the built-in telescopic cylinder drives the lifting U-shaped plate to drop down until the lifting wheel drops into the aluminum material. At this time, the lifting wheel contacts the sanding belt, and at the same time, driven by the insertion rod, the swing plate drives the clamping wheel to swing until the sanding belt contacts the side wall of the aluminum material, and the driving wheel drives the sanding belt to rotate, thereby simultaneously grinding the side wall and R angle of the aluminum material. The driving motor drives the sliding plate to slide horizontally to completely grind the side wall and R angle of one side of the aluminum material. The direction adjustment motor can rotate and adjust the clamped aluminum material, so that all the side walls and R angles of the aluminum material can be completely polished. The device can perform centralized polishing on the side walls and R angles of the aluminum material, and can polish the side walls and R angles of the aluminum material at the same time, which greatly improves the polishing efficiency, reduces the frequency of fixture replacement, and ensures processing accuracy.

[0024] 2. The polishing device maintains stable polishing pressure, angle and trajectory when polishing the R-angle of aluminum materials, so the polishing effect of the R-angle of aluminum materials is highly consistent;

[0025] 3. During the concentrated polishing of the aluminum sidewalls and R corners, the above-mentioned process of aluminum material feeding and aluminum cut end surface polishing is repeated to polish the aluminum cut end surface to be processed. This realizes the function of polishing the aluminum cut end surface to be processed during the concentrated polishing of the aluminum sidewalls and R corners, further improving the aluminum polishing efficiency.

[0026] 4. During the concentrated polishing of the side wall and R angle of the aluminum material, and after the polishing of the cut end face of the aluminum material to be processed is completed, the grinding wheel and the loading plate are reset in succession, and the rotating plate is rotated 180 degrees. At this time, the unloading plate is on the inside. After the polishing of the side wall and R angle of the aluminum material is completed, the rotating plate is rotated 180 degrees, and the unloading plate is close to the polished aluminum material. The electric telescopic cylinder drives the unloading clamping plates to slide towards each other and clamp the polished aluminum material. After that, the top plate and the unloading plate are reset in succession, and the rotating plate is rotated 180 degrees. The turntable rotates 180°, and the aluminum material that has completed polishing is sent to the outside of the operating table by the unloading clamping plate. The aluminum material that has completed the polishing of the cut end face 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. The above process can be repeated to continuously polish the aluminum material. The polishing device has a high degree of automation. The centralized polishing of the side wall and R corner of the aluminum material, the polishing of the cut end face of the aluminum material, and the loading and unloading of the aluminum material are all automated processes, which further improves the polishing efficiency of the aluminum material.

Then, the rotating plate 17 rotates until the loading carrier plate 55 faces downward, and the multi-stage telescopic cylinder 54 drives the loading carrier plate 55 to descend to the preset position. The pneumatic telescopic cylinder 57 drives the loading clamping plates 56 to slide toward each other and clamp the aluminum material 8.

After the polishing of the cut end surface of the aluminum material 8 is completed, the grinding wheel 41 is 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, and the clamping plate 46 Insert into the interior of the aluminum material 8 and contact the inner wall of the aluminum material 8, and then clamp the aluminum material 8 until the top plate 45 is against the end face of the aluminum material 8, then the loading carrier plate 55 and the rotating plate 14 are reset in succession, the lifting plate 11 is lowered until the sanding belt 34 contacts the top surface of the aluminum material 8, and the built-in telescopic cylinder 37 drives the lifting U-shaped plate 35 to descend until the lifting wheel 23 is lowered to the interior of the aluminum material 8. At this time, the lifting wheel 23 contacts the sanding belt 34, and at the same time, driven by the insertion rod 26, the swing plate 25 drives the clamping wheel 24 to swing until the sanding belt 34 contacts the side wall of the aluminum material 8, and the driving wheel 31 drives the sanding belt 3 4 rotates, thereby simultaneously polishing the side wall and R corner of the aluminum material 8; the driving motor 2 drives the sliding plate 10 to slide horizontally, thereby completely polishing the side wall and R corner of one side of the aluminum material 8; the direction adjustment motor 42 can rotate and adjust the clamped aluminum material 8, thereby completely polishing all the side walls and R corners of the aluminum material 8. The device can perform centralized polishing on the side walls and R corners of the aluminum material 8, and can polish the side walls and R corners of the aluminum material 8 at the same time, thereby greatly improving the polishing efficiency, reducing the frequency of fixture replacement, and ensuring processing accuracy;

[0053] The polishing device has stable polishing pressure, angle and trajectory when polishing the R-angle portion of the aluminum material 8, so the polishing effect of the R-angle portion of the aluminum material 8 is highly consistent;

[0054] During the concentrated polishing of the side walls and R-corner parts of the aluminum material 8, the above-mentioned process of loading the aluminum material 8 and polishing the cut end face of the aluminum material 8 is repeated to polish the cut end face of the aluminum material 8 to be processed, thereby achieving the function of polishing the cut end face of the aluminum material 8 to be processed during the concentrated polishing of the side walls and R-corner parts of the aluminum material 8, further improving the polishing efficiency of the aluminum material 8;

[0055] During the concentrated polishing of the side wall and R corner of the aluminum material 8, and after the polishing of the cut end face of the aluminum material 8 to be processed is completed, the grinding wheel 41 and the loading carrier plate 55 are reset in succession, and the rotating plate 17 rotates 180 degrees.
