Description

Technical Field

[0001] This utility model relates to the field of lens polishing technology, specifically a stop device for the rotating shaft of a polishing machine. Background Technology

[0002] In the field of lens processing, polishing is a crucial step that directly affects the optical performance and surface quality of the lens. During lens polishing, the rotating shaft is the key component that drives the polishing tool to achieve the desired surface finish. However, existing lens polishing machines have numerous problems with stopping the rotating shaft.

[0003] A search revealed that Chinese patent application number 202323588942.X discloses a stopping device for the rotating shaft of a polishing machine, comprising a fixed plate and a rotating shaft. A mounting platform is fixedly connected to the lower right side of the right end face of the fixed plate, and a connecting plate is fixedly connected to the right side of the upper end face of the mounting platform. A bidirectional lead screw is rotatably connected to the left end face of the connecting plate via a first turntable. Two lead screw nuts, distributed left and right, are threaded onto the outer wall of the bidirectional lead screw. This causes the bidirectional lead screw to rotate with the first turntable, thereby driving the two lead screw nuts to slide synchronously towards each other along the slide rail. This, in turn, causes the two mounting blocks and two stop plates to move towards each other, thus preventing the stop wheel from rotating through the pressure of the two stop plates. This further facilitates stopping the rotating shaft, achieving the characteristics of effortless stopping and preventing wear on the rotating shaft during stopping, thereby improving its service life.

[0004] Although the aforementioned application uses two stop plates to compress the stop wheel to prevent it from rotating, thus facilitating the stopping of the rotating shaft and achieving the characteristics of effortless stopping and preventing wear on the rotating shaft during stopping, thereby improving its service life, in actual use, using a bidirectional lead screw to drive the stop plates to clamp and stop the stop disc is problematic. Because the rotating shaft rotates at a high speed during lens polishing, sudden braking can easily generate a large impact force, causing the lead screw to deform and be damaged, thus affecting the stopping effect. Furthermore, stopping by rotating the lead screw is time-consuming and not convenient for timely and rapid stopping of the rotating shaft, affecting the lens polishing effect.

[0005] Therefore, it needs to be modified by setting a cylinder to drive the stop seat to cooperate with the stop disc to stop the rotating shaft. At the same time, when stopping, the stop clamp clamps the left and right sides of the stop disc to further improve the stopping effect, making it easier to quickly and stably stop the rotating shaft and convenient for users.

This device features a cylinder that drives a stopping seat to cooperate with a stopping disc to stop the rotating shaft. Simultaneously, during stopping, a stopping clamp clamps the left and right sides of the stopping disc, further improving the stopping effect. This facilitates quick and stable stopping of the rotating shaft and is convenient for users.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a stop device for the rotating shaft of a polishing machine, comprising a C-shaped frame, a drive motor fixedly connected to the left side of the C-shaped frame via a bracket, the output end of the drive motor penetrating into the interior of the C-shaped frame and fixedly connected to a rotating shaft via a coupling, a stop disc fixedly connected to the surface of the rotating shaft, a cylinder fixedly connected to the bottom of the inner wall of the C-shaped frame, a U-shaped lifting frame located directly below the stop disc fixedly connected to the output end of the cylinder, and a damping telescopic rod fixedly connected to the center of the bottom of the inner wall of the U-shaped lifting frame. The top of the telescopic rod is fixedly connected to an arc-shaped stop seat that is compatible with the stop disc. A support spring is sleeved on the surface of the damping telescopic rod. The top of the support spring is fixedly connected to the bottom of the arc-shaped stop seat. The bottom of the support spring is fixedly connected to the bottom of the inner wall of the U-shaped lifting frame. The lower sides of the arc-shaped stop seat are hinged with symmetrically arranged stop clips, and the tops of the two stop clips are inclined outwards. Connecting seats are fixedly connected to both sides of the inner wall of the U-shaped lifting frame. A connecting block is hinged to the inner side of the connecting seat. The inner side of the connecting block is slidably connected to the surface of the stop clip.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figures 1 to 4 As shown, the present invention provides a stop device for the rotating shaft of a polishing machine, comprising a C-shaped frame 1. A drive motor 2 is fixedly connected to the left side of the C-shaped frame 1 via a bracket. The output end of the drive motor 2 passes through the interior of the C-shaped frame 1 and is fixedly connected to a rotating shaft 3 via a coupling. A stop disc 4 is fixedly connected to the surface of the rotating shaft 3. A cylinder 5 is fixedly connected to the bottom of the inner wall of the C-shaped frame 1. A U-shaped lifting frame 6 located directly below the stop disc 4 is fixedly connected to the output end of the cylinder 5. A damping telescopic rod 7 is fixedly connected to the center of the bottom of the inner wall of the U-shaped lifting frame 6. An arc-shaped stop adapted to the stop disc 4 is fixedly connected to the top of the damping telescopic rod 7. The surface of the damping telescopic rod 7 is fitted with a support spring 9. The top end of the support spring 9 is fixedly connected to the bottom of the arc-shaped stop seat 8, and the bottom end of the support spring 9 is fixedly connected to the bottom of the inner wall of the U-shaped lifting frame 6. The surface of the support spring 9 is fitted with a retractable rubber sleeve (not shown). The lower sides of the left and right sides of the arc-shaped stop seat 8 are hinged with symmetrically arranged stop clips 10, and the tops of the two stop clips 10 are inclined outward. The inner walls of the U-shaped lifting frame 6 are fixedly connected with connecting seats 11. The inner side of the connecting seat 11 is hinged with a connecting block 12, and the inner side of the connecting block 12 is slidably connected to the surface of the stop clip 10.

[0019] refer to Figure 1 A stabilizing bearing 13 is fixedly connected to the right side of the surface of the rotating shaft 3. A stabilizing frame 14 is fixedly connected to the outer ring of the stabilizing bearing 13. The top of the stabilizing frame 14 is fixedly connected to the top of the inner wall of the C-shaped frame 1.

[0020] As a technical optimization of this utility model, by setting a stabilizing bearing 13 and a stabilizing frame 14 on the right side of the surface of the rotating shaft 3, the stabilizing bearing 13 can provide stable support for the rotating shaft 3, reduce the shaking and offset of the rotating shaft 3 during high-speed rotation, and ensure the rotation accuracy of the rotating shaft 3. The stabilizing frame 14 fixes the stabilizing bearing 13 to the top of the inner wall of the C-shaped frame 1, further enhancing the stability of the entire device and preventing the rotating shaft 3 from swinging when performing the stop action, which would affect the polishing effect.

[0021] refer to Figure 1A sliding sleeve 15 is fixedly connected to the left side of the U-shaped lifting frame 6. A stabilizing rod 16 is slidably connected inside the sliding sleeve 15. The bottom end of the stabilizing rod 16 is fixedly connected to the bottom of the inner wall of the C-shaped frame 1, and the top end of the stabilizing rod 16 is fixedly connected to the left side of the inner wall of the C-shaped frame 1 through a support plate.

[0022] As a technical optimization of this utility model, by setting a sliding sleeve 15 and a stabilizing rod 16 on the left side of the U-shaped lifting frame 6, a stable guiding effect is provided for the lifting and lowering movement of the U-shaped lifting frame 6. When the cylinder 5 pushes the U-shaped lifting frame 6 to rise or fall, the sliding sleeve 15 slides on the stabilizing rod 16, ensuring the accurate movement trajectory of the U-shaped lifting frame 6 and avoiding deviation or shaking of the U-shaped lifting frame 6 during movement. This allows the arc-shaped stop seat 8 and the stop clamp 10 to accurately cooperate with the stop plate 4, improving the reliability and stability of the stopping device. At the same time, the stabilizing rod 16 is fixedly connected to the left side of the inner wall of the C-shaped frame 1 through the support plate, further enhancing its support strength and ensuring the smooth progress of the entire stopping process. This helps to quickly and effectively stop the rotating shaft 3, thereby improving the efficiency and quality of lens polishing.

[0023] refer to Figure 1 The U-shaped lifting frame 6 has circular grooves on both the front and rear sides of its bottom, and guide columns 17 are slidably connected inside the circular grooves. The top of the guide column 17 is fixedly connected to the bottom of the arc-shaped stop seat 8.

[0024] As a technical optimization of this utility model, a guide post 17 and a circular groove are set between the bottom of the U-shaped lifting frame 6 and the arc-shaped stop seat 8. The guide post 17 slides in the circular groove, providing precise guidance for the up and down movement of the arc-shaped stop seat 8. This ensures that the arc-shaped stop seat 8 can accurately contact the stop plate 4 during the rising process and remain stable during the contact process, thereby improving the accuracy and reliability of the stop and avoiding the problem of poor stopping effect caused by the positional deviation of the arc-shaped stop seat 8.

[0025] refer to Figure 4 A dovetail block 18 is fixedly connected to the side of the connecting block 12 near the stop clamp 10. Both stop clamps 10 have dovetail grooves 19 on their outer sides that cooperate with the dovetail blocks 18. The surface of the dovetail block 18 is slidably connected to the inner wall of the dovetail groove 19.

[0026] As a technical optimization of this utility model, a dovetail block 18 and a dovetail groove 19 are provided between the connecting block 12 and the stop clamp 10, achieving a sliding connection between them. This connection method not only ensures the connection stability between the connecting block 12 and the stop clamp 10, but also makes the stop clamp 10 more flexible during movement. When the cylinder 5 pushes the U-shaped lifting frame 6 upward, the connecting block 12 can slide in the dovetail groove 19 through the dovetail block 18, accurately driving the stop clamp 10 to clamp the stop plate 4. This effectively reduces friction and wear between the connecting block 12 and the stop clamp 10, extending the service life of the device. At the same time, this precise sliding connection method ensures that the clamping force of the stop clamp 10 on the stop plate 4 is evenly distributed, improving the stopping effect and ensuring that the rotating shaft 3 can stop rotating quickly and stably, which is beneficial to improving the quality and efficiency of lens polishing.

[0027] refer to Figure 1 and Figure 4 Friction rings 20 are fixedly connected to both sides of the stop disc 4. Friction plates 21 that cooperate with friction rings 20 are fixedly connected to the inner side of the stop clamp 10 and the surface of the arc-shaped stop seat 8. The surface curvature of the arc-shaped stop seat 8 is the same as that of the stop disc 4 and the friction rings 20.

[0028] As a technical optimization of this utility model, friction rings 20 are provided on both sides of the stop disc 4, and friction plates 21 are provided on the inner side of the stop clamp 10 and the surface of the arc-shaped stop seat 8 to cooperate with them. The setting of friction rings 20 and friction plates 21 greatly increases the friction force during stopping, enabling the stopping device to stop the rotating shaft 3 more quickly and effectively. The curvature of the surface of the arc-shaped stop seat 8 is the same as that of the stop disc 4 and the friction rings 20, which can ensure full contact between the arc-shaped stop seat 8 and the stop disc 4, further improving the effect of friction force.

[0029] The working principle and usage process of this utility model are as follows: During normal operation, the drive motor 2 drives the rotating shaft 3 to rotate via a coupling. The stabilizing bearing 13 and the stabilizing frame 14 on the rotating shaft 3 ensure its rotational stability to achieve the polishing operation of the lens. When it is necessary to stop the rotating shaft 3, the cylinder 5 at the bottom of the inner wall of the C-shaped frame 1 is activated. The output end of the cylinder 5 pushes the U-shaped lifting frame 6 to rise. The sliding sleeve 15 on the left side of the U-shaped lifting frame 6 slides on the stabilizing rod 16 to ensure its accurate rising trajectory. As the U-shaped lifting frame 6 rises, the arc-shaped stop seat 8 approaches the stop plate 4. The damping telescopic rod 7 and the support spring 9 play a buffering role, reducing the impact of the rising motion. The impact force causes cylinder 5 to continue extending. Connecting block 12 slides in dovetail groove 19 on the outside of stop clamp 10 via dovetail block 18, causing stop clamp 10 to clamp the friction rings 20 on both sides of stop disc 4. Friction plates 21 on the inside of stop clamp 10 and the surface of arc-shaped stop seat 8 are in full contact with friction rings 20. Both friction plates 21 and friction rings 20 are fixed with bolts and can be replaced after wear to avoid affecting the stopping effect. The friction force is used to stop the rotation of rotating shaft 3 quickly and stably, completing the stopping operation. This avoids affecting the lens polishing effect due to the continuous rotation of rotating shaft 3, thus improving the quality and efficiency of lens polishing.
