[0002] Optical lenses need to be installed in a dish for polishing. However, the flatness of the dish will be affected during long-term use, which will affect the polishing quality of the optical lenses. Therefore, it is necessary to repair the dish to ensure the polishing quality of the optical lenses.

The arched strip is mounted on the lower center of the base plate, and grooves are provided on both the left and right ends of the base plate. The upper left side of the L-shaped rack one is slidably connected to the left groove, and the upper right side of the L-shaped rack two is slidably connected to the right groove. The lower end of the rack two is slidably connected to the lower end of the inner part of the arched strip. The upper left side of the rack one and the… A clamping plate is installed on the upper right side of rack two. The lower end of the clamping plate is slidably connected to the upper end of the base plate. A horizontal gear shaft is rotatably connected inside the arched strip. Gears are installed on the gear shafts, and these gears mesh with rack one and rack two respectively. An electric push rod is installed on the lower right side of the base plate. The telescopic end of the electric push rod is connected to the right end of rack two. When the electric push rod is working, it can move rack two left and right. When rack two moves to the left, the meshing of the gears with rack one and rack two causes rack one to move to the right, thereby bringing the two clamping plates closer together to clamp and fix the different sized jigs on the pad strip, aligning them with the lower side of the grinding mechanism. Dust extraction unit: installed at both ends of the arched plate.

[0004] This type of grinding and repairing machine has the following disadvantages: it grinds and repairs the dish held by the clamping plate through the grinding mechanism, but some of the lenses are convex or concave lenses, and the corresponding inside of the dish is a curved surface. This makes it impossible to grind the curved surface inside the dish, resulting in poor grinding and repair effect. Therefore, we propose a grinding and repairing machine. Utility Model Content

[0022] Clamping and swinging mechanism 7: It includes a mounting plate 71, a first rotating ball 72, a first connecting rod 73, a second connecting rod 75, a turntable 76, a rotating seat 77, a second rotating ball 78, and a clamping assembly 79. The mounting plate 71 is located in the center of the mounting groove 1 in the middle of the dressing table 1. The first rotating ball 72 is rotatably connected within the rotating groove in the middle of the mounting plate 71. The first connecting rod 73 is located at the center of the upper end of the first rotating ball 72, and the second connecting rod 75 is located at the center of the lower end of the first rotating ball 72 (the central axes of the first connecting rod 73 and the second connecting rod 75 are collinear). The turntable 76 is rotatably connected to the center of the bottom wall of the first mounting groove 1. A rotating seat 77 is located at the eccentric position at the upper end of the turntable 76. The second rotating ball 78 is rotatably connected inside the rotating seat 77. The lower end of connecting rod 75 is fixedly connected to the upper middle part of rotating ball 78. Clamping assembly 79 is used for clamping and fixing the dish. Clamping assembly 79 includes clamping seat 791, slider 792 and clamping block 793. The upper end of connecting rod 73 is provided with clamping seat 791. Sliding sliders 792 are symmetrically distributed in the groove in the middle of clamping seat 791. Clamping block 793 is provided at the upper end of each slider 792. Clamping assembly 79 also includes a bidirectional lead screw 794 and a knob 795. The bidirectional lead screw 794 is rotatably connected to the middle of the right side wall of the groove. The bidirectional lead screw 794 is threadedly connected to the threaded hole in the middle of the slider 792. The bidirectional lead screw 794 extends to the outside of the groove. Knob 795 is provided on the bidirectional lead screw. On the left side of 794, the clamping and swinging mechanism 7 also includes a second motor 74. The second motor 74 is located in the middle of the bottom wall of the mounting groove 2 at the lower end of the polishing table 1.

The input end of the second motor 74 is electrically connected to the output end of the microcontroller 8. The dish is placed between the two clamping blocks 793, and then the knob 795 is turned to drive the bidirectional lead screw 794. The bidirectional lead screw 794 drives the two sliders 792 to drive the two clamping seats 791 to slide towards each other, thereby clamping the dish. Then, the microcontroller 8 turns on the first motor 5, which drives the grinding head 6 to rotate. Then, the microcontroller 8 turns on the linear guide rail 3, and the moving part of the linear guide rail 3... The moving seat causes the grinding head 6 to contact the dish, and then the microcontroller 8 turns on the second motor 74. The second motor 74 drives the turntable 76 to rotate, causing the rotating seat 77 to revolve around the central axis of the turntable 76. Since the central axis of the turntable 76 coincides with the central axis of the rotating ball 72, the rotation of the turntable 76 will cause the second connecting rod 75 to deflect. The second connecting rod 75 drives the rotating ball 72 to drive the first connecting rod 73 to deflect in the opposite direction of the second connecting rod 75. The first connecting rod 73 drives the clamping seat 791 to drive the dish to deflect synchronously, realizing the rotation and shaking grinding of the dish. The clamping component 69 holds the dish and performs rotation and shaking grinding, so that the grinding surface of the dish has more contact with the grinding head, resulting in a better grinding effect.

[0023] The working principle of the grinding and repairing machine provided by this utility model is as follows: When grinding and repairing a dish, the dish needs to be held on the upper end of the clamping seat 791 first, and the dish is placed between two clamping blocks 793. Then, the knob 795 is turned to drive the bidirectional lead screw 794. The bidirectional lead screw 794 drives the two sliders 792 to drive the two clamping seats 791 to slide towards each other, thereby clamping the dish. Then, the microcontroller 8 turns on the motor 5, which drives the grinding head 6 to rotate. Then, the microcontroller 8 turns on the linear guide rail 3, and the moving part of the linear guide rail 3 moves to drive the grinding. The head 6 contacts the dish, and then the microcontroller 8 turns on the second motor 74. The second motor 74 drives the turntable 76 to rotate, causing the rotating seat 77 to revolve around the central axis of the turntable 76. Since the central axis of the turntable 76 coincides with the central axis of the rotating ball 72, the second connecting rod 75 will deflect while the turntable 76 rotates. The second connecting rod 75 drives the rotating ball 72 to drive the first connecting rod 73 to deflect in the opposite direction of the second connecting rod 75. The first connecting rod 73 drives the clamping seat 791 to deflect the dish synchronously, realizing the rotation and shaking grinding of the dish.
