Description

Technical Field

[0001] This utility model relates to the field of cavity mirror surface processing technology, and more specifically, to a cavity mirror surface processing device. Background Technology

[0002] Cavity mirror finishing refers to the ultra-high precision polishing of the surface of an internal cavity to achieve a smoothness approaching that of an optical mirror (surface roughness Ra≤0.01μm), while ensuring shape accuracy (such as flatness and roundness) and microstructural integrity. Its core objective is to eliminate micro-scratches, pits, and subsurface damage layers on the inner wall of the cavity to achieve specific physical properties (such as light / particle reflectivity, low fluid resistance, and sterility). Common objects processed include the inner walls of optical instrument cavities, precision valve cavities, and vacuum equipment cavities, achieving micron- or even nanometer-level smoothness to meet high-end requirements such as optical reflection, precision sealing, and low fluid resistance.

[0003] Because fine grinding is performed inside the workpiece, such as the inner cavity of a tube, the operation method is very different from that of grinding the outer surface, resulting in greater operational difficulty. Existing cavity mirror surface processing work requires a long time for clamping and fixing the tubular workpiece and adjusting the equipment in the early stage, which is not very convenient. For fixing tubes of different diameters, different types of clamps are often required to match and fix them, which increases production costs.

[0004] In summary, in order to improve the efficiency and convenience of fine grinding of the inner cavity of the tube and reduce production costs, it is necessary to solve the problems of long time consumption and poor convenience in clamping and fixing tubular workpieces and adjusting equipment in the existing cavity mirror processing, and the need to match different fixtures for different diameter tubes. The goal is to make the processing more efficient and convenient, flexibly adapt to the fixing of tubes of different diameters, and effectively control costs. Utility Model Content

[0021] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0022] Refer to the instruction manual appendix Figures 1 to 6 A cavity mirror surface processing device includes a slide rail 1, an N-shaped plate 2 disposed on the upper side of the slide rail 1, a moving mechanism disposed on the slide rail 1 for driving the N-shaped plate 2 to move left and right, a lifting block 4 disposed on the inner side of the N-shaped plate 2, a lifting mechanism disposed on the N-shaped plate 2 for adjusting the height position of the lifting block 4, a grinding motor 5 fixedly connected to the right end of the lifting block 4, a fixed rod 7 fixedly connected to the output end of the grinding motor 5 for driving the fixed rod 7 to rotate, a grinding wheel 10 fixedly connected to the end of the fixed rod 7 away from the grinding motor 5, and the rear end of the slide rail 1... A support frame 11 is fixedly connected to the right side. A top plate 12 is fixedly connected to the upper end of the support frame 11. Suspension plates 13 are symmetrically fixedly connected to the left and right ends of the bottom of the top plate 12. Rotating cylinders 14 are movably connected through the lower ends of the two suspension plates 13. A clamping and positioning mechanism is provided on the rotating cylinders 14. The clamping and positioning mechanism includes an execution component and a drive component. The execution component is used to clamp and position the tubular workpiece that passes through. The drive component is used to drive the execution component to work. A rotating mechanism is provided on the top plate 12 and the suspension plates 13. The rotating mechanism is used to drive the two rotating cylinders 14 to rotate simultaneously.

[0023] It should be noted that after the tubular workpiece is inserted into the two rotating cylinders 14, it is centered and fixed by the clamping and positioning mechanism, so that the center line of the tubular workpiece coincides with the center line of the two rotating cylinders 14. The lifting mechanism is used to raise the grinding wheel 10 and make it contact the inner wall of the tubular workpiece. In this way, the waste generated during grinding will be concentrated in the lower part of the tubular workpiece, avoiding affecting the mirror surface processing. The rotating mechanism drives the tubular workpiece to rotate by controlling the two rotating cylinders 14. In conjunction with starting the grinding motor 5, the fixed rod 7 drives the grinding wheel 10 to rotate. The moving mechanism further drives the grinding wheel 10 to grind from the inner side of the left end of the tubular workpiece all the way to the right end, completing the mirror surface processing of the tubular workpiece cavity.

[0024] Refer to the instruction manual appendix Figure 5 and Figure 6 The execution component includes through holes 901 that are opened through the upper and lower surfaces of the rotating cylinder 14. Fixing posts 902 are movably installed in both the upper and lower through holes 901. An arc-shaped clamping plate 903 is fixedly connected to the relatively close end of the two fixing posts 902, and a connecting plate 904 is fixedly connected to the relatively far end of the two fixing posts 902.

[0025] It should be noted that by moving the two connecting plates 904 closer to each other, the two arc-shaped clamping plates 903 are pushed by the fixed column 902 to squeeze and position the tubular workpiece that is inserted into the rotating cylinder 14.

[0026] Refer to the instruction manual appendix Figure 6 The drive assembly includes a fixed base 905 fixedly connected to the surface of the rotating cylinder 14. A rectangular frame 906 is fixedly connected to one end of the fixed base 905 away from the rotating cylinder 14. A bidirectional screw 907 is rotatably connected to the inner side of the rectangular frame 906. Two connecting plates 904 are symmetrically threaded to the outer sides of both ends of the bidirectional screw 907. A knob 908 is rotatably connected to the outer side of the rectangular frame 906. The knob 908 is fixedly connected to the bidirectional screw 907 through a shaft.

[0027] It should be noted that rotating knob 2 908 drives the bidirectional screw 907 to rotate, and the bidirectional screw 907 drives the two connecting plates 904 to move relative to each other.

[0028] Refer to the instruction manual appendix Figure 4 The rotating mechanism includes a dual-axis motor 801 fixedly connected to the bottom center of the top plate 12. The output end of the dual-axis motor 801 is fixedly connected to a rotating rod 802. The dual-axis motor 801 is used to drive the rotating rod 802 to rotate. The two ends of the rotating rod 802 are respectively rotatably connected between two suspension plates 13. Gears 803 are fixedly connected to the outer sides of the two ends of the rotating rod 802. The two gears 803 are respectively meshed with gear rings 804. The two gear rings 804 are respectively fixedly connected to the outer sides of the two rotating cylinders 14.

[0029] It should be noted that starting the dual-axis motor 801 drives the rotating rod 802 to rotate, and the rotating rod 802 then drives the gear ring 804 to rotate through the gear 803, and the gear ring 804 further drives the rotating cylinder 14 to rotate.

[0030] Refer to the instruction manual appendix Figure 5 Two limiting rings 15 are fixedly connected to the outer side of the rotating cylinder 14, and the two limiting rings 15 are symmetrically arranged on the left and right sides of the suspension plate 13.

[0031] It should be noted that the rotating cylinder 14 can rotate freely, and the two limiting rings 15 can prevent the rotating cylinder 14 from detaching from the suspension plate 13.

[0032] Refer to the instruction manual appendix Figure 3 The lifting mechanism includes a threaded rod 601 rotatably connected to the inner side of the N-shaped plate 2, a lifting block 4 threadedly connected to the outer side of the threaded rod 601, and a knob 602 rotatably connected to the upper end of the N-shaped plate 2. The knob 602 is fixedly connected to the threaded rod 601 through a shaft.

[0033] It should be noted that rotating knob 602 causes threaded rod 601 to rotate, and threaded rod 601 further drives lifting block 4 to move up and down, thereby adjusting the grinding wheel 10 to a suitable mirror surface processing position.

[0034] Refer to the instruction manual appendix Figure 2 The moving mechanism includes a threaded rod 301 rotatably connected to the inner side of the slide rail 1, a moving plate 302 threadedly connected to the outer side of the threaded rod 301, the upper end of the moving plate 302 being fixedly connected to the bottom of the N-shaped plate 2, a moving motor 303 being fixedly connected to the surface of the slide rail 1, the output end of the moving motor 303 being fixedly connected to the threaded rod 301, and the moving motor 303 being used to drive the threaded rod 301 to rotate.

[0035] It should be noted that starting the moving motor 303 drives the threaded rod 301 to rotate, and the threaded rod 301 drives the moving plate 302 to move, thereby controlling the grinding wheel 10 to penetrate into the cavity of the tubular workpiece to perform all-round mirror surface processing.

[0036] Working principle: After the tubular workpiece is inserted into the two rotating cylinders 14, it is centered and fixed by the clamping and positioning mechanism. Specifically, rotating knob 2 908 drives the bidirectional screw 907 to rotate. The bidirectional screw 907 drives the two connecting plates 904 to move closer together. The fixing column 902 pushes the two arc-shaped clamping plates 903 to squeeze and position the tubular workpiece inserted into the rotating cylinder 14, so that the center line of the tubular workpiece coincides with the center line of the two rotating cylinders 14. Using the lifting mechanism, rotating knob 1 602 drives the threaded rod 2 601 to rotate. The threaded rod 2 601 further drives the lifting block 4 to move up and down, thereby adjusting the grinding wheel 1. The first contact point is the inner wall of the tubular workpiece, completing the preliminary preparation work. Then, using the rotating mechanism, the dual-axis motor 801 is started to drive the rotating rod 802 to rotate. The rotating rod 802 then drives the gear ring 804 to rotate through the gear 803. The gear ring 804 further drives the rotating cylinder 14 to rotate, thereby causing the tubular workpiece to rotate. In conjunction with starting the grinding motor 5, the fixed rod 7 drives the grinding wheel 10 to rotate. Using the moving mechanism, the moving motor 303 is started to drive the threaded rod 301 to rotate. The threaded rod 301 drives the moving plate 302 to move to the right. The grinding wheel 10 starts from the inner side of the left end of the tubular workpiece and grinds all the way to the right end, completing the mirror surface processing of the tubular workpiece cavity.

[0037] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
