Description

Technical Field

[0001] The utility model relates to the field of workpiece processing, in particular to a surface polishing device for metal parts. Background Art

[0002] Surface polishing of metal parts is a processing method that uses mechanical, chemical or electrochemical effects to reduce the surface roughness of metal workpieces and obtain a bright and flat surface.

[0003] After retrieval, Chinese Patent Publication No.: CN218904857U discloses a surface polishing device for metal parts, including a workbench box. Both sides of the top of the workbench box are fixedly connected with fixing plates. A polishing equipment body is installed between the two fixing plates. In this surface polishing device for metal parts, the waste chips on the workbench box can be swept by rotating the brush to prevent the waste chips from adhering to the workbench box. The swept waste chips are blocked by the scraper, and the waste chips on the workbench box can be better scraped off by the scraper. When the two scrapers move to a certain position, the waste chips can be pushed to the position of the cross groove by the scraper and fall into the chip collection box arranged in the workbench box through the cross groove for collection, improving the practicability of the device.

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0033] Refer to Figure 1 - Figure 2 As shown in FIG.

[0034] Refer to Figure 2 、 Figure 3 And Figure 5 As shown in FIG.

[0035] Refer to Figure 2 、 Figure 3 And Figure 5, a fixing device 67 is provided at the top of the moving rod 64. The fixing device 67 is a device for fixing metal parts, and this technology is an existing technology that can be realized by those skilled in the art. Therefore, it will not be described in detail in this case. An installation groove 68 is opened at the left end of the moving rod 64. A rotating shaft 69 is slidably connected to the inner wall of the installation groove 68. The sliding direction of the rotating shaft 69 is up and down. A first cleaning strip 610 is penetrated and rotatably connected to the outer wall of the rotating shaft 69. A placement groove 611 is opened at the top of the first cleaning strip 610. A second cleaning strip 612 is rotatably connected to the inner wall of the placement groove 611. The outer wall materials of the first cleaning strip 610 and the second cleaning strip 612 are both set to silicone. Through the material setting, it is ensured that the first cleaning strip 610 and the second cleaning strip 612 can fit with the top of the filter plate 63 or the inner wall of the housing 5 to ensure the cleaning effect.

[0036] Refer to Figure 2 , Figure 4 And Figure 6 , a fixing component 7 is arranged inside the second cleaning strip 612. The fixing component 7 includes a sliding groove 71 opened on the inner wall of the second cleaning strip 612. A pressing block 72 is slidably connected to the inner wall of the sliding groove 71. A triangular block 73 is fixedly connected to the bottom end of the pressing block 72. A clamping block 74 is slidably connected to the bottom inner wall of the sliding groove 71. The front end of the clamping block 74 is elastically connected to the inner wall of the sliding groove 71 through a spring 75. One end of the spring 75 is fixedly connected to the front end of the clamping block 74, and the other end of the spring 75 is fixedly connected to the inner wall of the sliding groove 71. The elastic force of the spring 75 is greater than the gravity of the pressing block 72. A sliding groove 76 is opened on the inner wall of the first cleaning strip 610. A triangular groove 77 is opened at the top end of the clamping block 74. The shape of the triangular block 73 is the same as that of the triangular groove 77, and the triangular block 73 and the triangular groove 77 are in the same plane. Through the consistent shape setting, it is ensured that the up and down movement of the triangular block 73 can make the clamping block 74 move horizontally.

[0037] Working principle: When in use, when the staff needs to polish the surface of the metal part, the staff first moves upward through the fixing device 67, so that the fixing device 67 drives the moving rod 64 to move upward. When it moves to the area above the filter plate 63 where the rotating shaft 69 is located, the staff manually takes out the first cleaning strip 610 and the second cleaning strip 612, and makes the first cleaning strip 610 in a horizontal state and the second cleaning strip 612 in a vertical state.

[0038] After taking out, the staff releases the moving rod 64. At this time, due to the influence of gravity on the moving rod 64, the moving rod 64 moves downward, and the rotating shaft 69 moves upward relative to the moving rod 64 inside the installation groove 68. Therefore, the horizontal positions of the first cleaning strip 610 and the second cleaning strip 612 can remain unchanged.

[0039] During the process of rotating the second cleaning strip 612, the clamping block 74 slides inside the sliding groove 76. When it slides to the exactly vertical position, at this time, the clamping block 74 moves to the end of the sliding groove 76. Since the end of the sliding groove 76 is deeper, at this time, the clamping block 74 is driven by the spring 75 to enter a deeper position of the sliding groove 76. Therefore, the second cleaning strip 612 can maintain a vertical state.

[0040] When the positions of the first cleaning strip 610 and the second cleaning strip 612 are set, the staff places the metal part to be polished on the fixing device 67 to fix the metal part to be polished, and then starts the cylinder 3, so that the output shaft of the cylinder 3 pushes the grinding wheel 4 downward, so that the bottom end of the grinding wheel 4 can contact the surface of the metal part.

[0041] When the grinding wheel 4 can contact the surface of the metal part, the staff starts the motor 62, so that the motor 62 drives the cross block 66 to rotate. Thus, the cross block 66 drives the moving rod 64 to rotate through the cross groove 65, so that the fixing assembly 7 rotates and the metal part rotates to achieve a polishing effect. During the polishing process, the motor 62 pushes the inner wall of the cross groove 65 through the cross block 66, so that the moving rod 64 rotates, so that the first cleaning strip 610 and the second cleaning strip 612 rotate to achieve the effect of cleaning the filter plate 63 and the inner wall of the housing 5 during the polishing process.

[0042] When manual cleaning is required, the staff first pulls up the fixing device 67. When the installation groove 68 moves to the area above the filter plate 63, the staff first presses the pressing block 72, so that the pressing block 72 drives the triangular block 73 to move downward. Thus, the triangular block 73 makes the clamping block 74 leave the deep part of the sliding groove 76 through the triangular groove 77. At this time, the second cleaning strip 612 can rotate.

[0043] When the second cleaning strip 612 rotates into the placement groove 611, the staff rotates the first cleaning strip 610 so that the first cleaning strip 610 enters the installation groove 68. At this time, the staff can perform manual cleaning without cleaning dead corners.

[0044] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
