[0037] As a preferred embodiment, please refer to Figure 1 and Figure 2The rotating mechanism 400 includes a mounting frame 410 and a second rotating driving member 420. The output shaft of the second rotating driving member 420 is fixedly connected to the mounting frame 410 for driving the mounting frame 410 to rotate. The upper end of the swing rod 210 is rotatably mounted on the mounting frame 410 via a pin shaft. Since the upper end of the swing rod 210 is rotatably connected to the mounting frame 410, when the first rotating driving member 330 drives the transmission rod 310 to rotate and drives the guide sleeve 320 to rotate, the swing rod 210 can swing back and forth.

[0040] In order to better understand the present invention, the following Figure 1 - Figure 4 The working principle of the technical solution of the utility model is described in detail:

[0041] When in use, the optical lens is placed on the workbench 510 with the concave or convex surface of the lens facing upwards. The two clamping grooves 110 can be brought close to each other and clamp the optical lens by rotating the driving shaft forwardly. The swing amplitude of the swing rod 210 is adjusted according to the diameter of the lens. The screw is rotated forwardly or reversely. Since the telescopic section 312 is limited by the fixed section 311, when the screw rotates, the telescopic section 312 can be driven to move in the opposite direction along the length of the fixed section 311, thereby adjusting the length of the transmission rod 310. When the length of the transmission rod 310 changes, the swing amplitude of the swing rod 210 will change accordingly, so that the swing amplitude of the swing rod 210 is adapted to the curvature of the curved surface. The spring can apply an elastic force to the polishing member 220, so that the polishing head is pressed against the concave or convex surface of the lens. By manipulating the first rotating driving member 330, so that the first rotating driving member 330 can drive the transmission rod 310 to rotate, and drive the guide sleeve 320 to rotate. Since the guide sleeve 320 is rotatably connected to one end of the transmission rod 310, and the upper end of the swing rod 210 is rotatably connected to the mounting bracket 410, during the rotation of the guide sleeve 320, the swing rod 210 can swing back and forth, thereby driving the polishing member 220 to swing back and forth. Then, by manipulating the second rotating driving member 420, the second rotating driving member 420 can drive the mounting bracket 410 to rotate, and drive the swing mechanism 300 and the swing rod 210 to rotate, thereby rotating the polishing member 220. During the reciprocating swing and rotation of the polishing member 220, the polishing head can polish the entire curved surface. The present polishing device can polish the concave and convex surfaces of an optical lens, and can adapt to optical lenses of multiple specifications and multiple curvatures.

[0042] The lens curved surface polishing device provided by the utility model has the following beneficial effects:

[0043] (1) The spring can apply elastic force to the polishing member 220, so that the polishing head is pressed against the concave surface or convex surface of the lens. When the polishing member 220 reciprocates and rotates, the polishing head can polish the entire curved surface;

[0044] (2) By rotating the screw rod forward or reversely, since the telescopic section 312 is limited by the fixed section 311, when the screw rod rotates, the telescopic section 312 can be driven to move in the opposite direction along the length of the fixed section 311, thereby adjusting the length of the transmission rod 310. When the length of the transmission rod 310 changes, the swing amplitude of the swing rod 210 will change accordingly, so that the swing amplitude of the swing rod 210 is adapted to the curvature of the curved surface;
