Description

Technical Field

[0001] This utility model relates to the field of optical mirror technology, and in particular to a surface polishing and grinding device for the production of optical mirrors. Background Technology

[0002] Optical mirrors are typically key components in optical devices and are widely used in fields such as astronomical observation, aerospace remote sensing, laser technology, and medical equipment. As the performance requirements of optical systems in various fields continue to rise, extremely stringent standards have been set for the precision and surface quality of optical mirrors. Among these, surface polishing is a crucial process that determines the performance of an optical mirror, and its processing quality directly affects the mirror's reflectivity, scattering rate, and core imaging quality.

[0003] The surface polishing and grinding equipment for optical mirrors has gradually revealed many drawbacks in the face of the increasing demand for high precision. In some conventional polishing equipment, the use of fixed polishing tools makes it difficult to flexibly adapt to mirrors with different curvatures, sizes and shapes. For mirrors with complex curved surfaces, conventional equipment often cannot guarantee the uniformity of polishing, resulting in inconsistent roughness in different areas of the mirror surface, which seriously affects the consistency of optical performance. In addition, the automation level of traditional equipment is low, and most operations rely on manual intervention, including manual pressing and positioning. This not only increases labor costs and labor intensity, but also easily leads to processing errors, making it difficult to achieve large-scale, high-quality and stable production. Therefore, it is not convenient for daily use and reduces grinding efficiency. Utility Model Content

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, a semi-circular plate is used in conjunction with a rotating shaft to rotate and engage along the outer wall of a U-shaped plate.

The machine can be precisely stopped at a designated position by observing the pointer and scale. Therefore, the position of the grinder can be effectively and precisely adjusted according to the usage requirements to meet the grinding effect and facilitate the operation of the operator.

[0031] Please see the appendix Figure 1 - Appendix Figure 3 This utility model provides an embodiment of a surface polishing and grinding device for producing optical mirrors, comprising a worktable 1, a U-shaped plate 15 fixedly connected to the bottom right side of the worktable 1, a rotating shaft 14 rotatably connected to the front right side of the U-shaped plate 15, a semi-circular plate 4 rotatably connected to the outer wall of the rotating shaft 14, a connecting plate 16 fixedly connected to the rear right side of the U-shaped plate 15, a buckle 21 provided on the front side of the connecting plate 16, a locking hole 20 rotatably connected to the inner side of the buckle 21, and hollow columns 11 fixedly connected to the outer walls of both the semi-circular plate 4 and the U-shaped plate 15. A Z-shaped rotating rod 12 is rotatably connected to the opposite side of multiple hollow columns 11. A threaded column 22 is fixedly connected to the other end of the Z-shaped rotating rod 12. A movable column 19 is threadedly connected to the outer wall of the threaded column 22. A threaded knob 13 is threadedly connected to the top of the movable column 19.

The adjustment mechanism 2 is used to adjust the grinding position. A circular hole 17 is opened on the inner side of the hollow column 11. The inner side of the circular hole 17 is slidably connected to the outer wall of the movable column 19.

[0032] Specifically, the rotating shaft 14 has rotational flexibility, and the optimized seal effectively prevents the intrusion of external impurities, ensuring long-term stability. A semi-circular plate 4 is sleeved on the outer wall of the rotating shaft 14, realizing quick connection with the locking hole 20. The locking hole 20 improves the stability and service life of the connection. Z-shaped rotating rods 12 are rotatably connected to the opposite side of the hollow column 11, and the other end of the Z-shaped rotating rod 12 is fixedly connected to a threaded column 22. The threaded column 22 is made of stainless steel, which facilitates effective rotation by the operator.

[0033] Please see the appendix Figure 3 - Appendix Figure 5 The adjustment mechanism 2 includes a slide rod 205. The outer wall of the slide rod 205 is fixedly connected to the top inner side of the workbench 1. An L-shaped plate 202 is fixedly connected to the top right side of the workbench 1. A servo motor 201 is fixedly connected to the bottom inner side of the L-shaped plate 202. The output end of the servo motor 201 passes through the top of the slide rod 205 and is fixedly connected to a lead screw 206. A moving plate 203 is threadedly connected to the outer wall of the lead screw 206. A grinder 207 is fixedly connected to the bottom end of the moving plate 203. A stabilizing plate 204 is fixedly connected to the inner right side of the slide rod 205. A pointer 208 is fixedly connected to the bottom left side of the moving plate 203. A scale 209 is fixedly connected to the middle left side of the workbench 1. Fluorescent plates 3 are fixedly connected to the top front side of the workbench 1. Both fluorescent plates 3 are symmetrically designed.

[0034] Specifically, the frictional resistance is reduced by the central hole 5 at the top of the slide rod 205. Between the output end and the top of the slide rod 205, on the outer wall of the lead screw 206, there is a movable plate 203 that can move along the axial direction of the lead screw 206 via a threaded connection. The grinding machine 207 can flexibly adjust the grinding speed according to the processing requirements of different materials, ensuring the consistency and efficiency of grinding quality. On the right side inside the slide rod 205, a stabilizing plate 204 is fixedly connected to enhance stability.

[0035] Please see the appendix Figure 1 - Appendix Figure 3 A mounting plate 9 is fixedly connected to the top left side of the workbench 1. A battery 8 is fixedly connected to the middle left side of the mounting plate 9. A handle 7 is fixedly connected to the middle left side of the workbench 1. An anti-slip plate 6 is fixedly connected to the bottom of the workbench 1. A controller 10 is fixedly connected to the bottom left side of the workbench 1.

All the holes 5 are set at the same horizontal height.

[0036] Specifically, the battery 8 has high-energy fast charging capability and built-in intelligent battery management, which can monitor the battery status in real time. On the workbench 1 of the equipment, a handle 7 is installed in the middle of the left side. The anti-slip plate 6 is made of high-strength rubber material, which can significantly increase the friction between the equipment and the contact surface, effectively preventing the equipment from sliding or tilting during operation, and ensuring the safety and stability of the operation.

[0037] Working principle: When polishing an optical mirror, firstly, the semicircular plate 4 and the rotating shaft 14 are rotated and engaged along the outer wall of the U-shaped plate 15. When the other end of the semicircular plate 4 is engaged with the buckle 21, the rotating hole 20 is used to limit its position. Then, the optical mirror is placed between the semicircular plate 4 and the U-shaped plate 15. The Z-shaped rotating rod 12 is rotated to adjust the moving column 19 inward along the inner circular hole 17 of the hollow column 11. The adjustment is stopped when one end of the moving column 19 contacts the optical mirror. Then, the threaded knob 13 is turned to press the pressing plate 18 onto the surface of the optical mirror for limiting and fixing. This effectively prevents the optical mirror from shaking during polishing, improves the polishing effect, and can limit the position of optical mirrors of different specifications to meet usage requirements.

[0038] Then, the servo motor 201 fixedly connected to the L-shaped plate 202 is started, thereby driving the lead screw 206 to rotate through the slide rod 205. At this time, when the lead screw 206 is rotating, it cooperates to move the movable plate 203 connected to the outer wall vertically downward along the outer wall of the stabilizing plate 204. The pointer 208 and the scale 209 are used to observe and accurately stop at the designated position. Finally, the polishing machine 207 is started to polish the optical reflector. Therefore, the position of the polishing machine 207 can be accurately adjusted according to the usage requirements to meet the polishing effect and facilitate the operation of the operator.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
