[0047] The working principle of the utility model is as follows: an ultra-thick lens polishing fixture is used, the optical lens to be polished is placed in the placement groove 11, the knob shaft 29 is pulled outward, the knob shaft 29 drives the connecting plate 31 to move in the direction away from the first bevel gear 36 through the convex plate 30, at this time the tension spring 35 becomes longer, the knob shaft 29 is operated to rotate, through the connection of the convex plate 30, the connecting plate 31, and the spring 35, the installation cylinder 34 and the first bevel gear 36 are driven to rotate as a whole, the first bevel gear 36 rotates to drive the second bevel gear 21 and the belt The movable shaft 26 rotates, and the drive shaft 26 rotates to drive the adjusting disk 38 to rotate. The adjusting disk 38 rotates to change the position of the arc hole 22, and guides the movement of the driving rod 23, so that the multiple clamping disks 24 are close to the center of the adjusting disk 38. Through the V-shaped gasket 39, when the front and back surfaces are polished, they are in contact with the surfaces of different edges of the lens for extrusion and clamping. When the knob shaft 29 is loosened, the connecting disk 31 drives the multiple protrusions 12 to be clamped in the adapter groove 32 under the action of the spring 35, preventing the installation tube 34 from rotating and maintaining the stability of the clamping. The positioning is performed by threaded fixation of the screw rod 28 and the first threaded hole 27. After the height of the L-shaped rod 14 is adjusted, the motor 6 is started. The output end of the motor 6 drives the sleeve 8 and the L-shaped rod 14 to rotate as a whole. The rotation of the L-shaped rod 14 drives the concave polishing disc 25 to rotate, and the surface of the lens is polished. During the rotation of the sleeve 8, the driving wheel 40 is driven to rotate. After the driving wheel 40 rotates, the driven wheel 13 is driven to rotate through the belt 7, and then the linkage shaft 15 is driven to rotate. The rotation of the linkage shaft 15 drives the third bevel gear 16 to rotate. The rotation of the third bevel gear 16 drives the fourth bevel gear 17 to rotate. The rotation of the fourth bevel gear 17 drives the fan blade 19 to rotate through the support shaft, and the suspended polishing powder generated by polishing is blown onto the filter 10 for accumulation. When it is necessary to polish the other side of the lens, the concave polishing disc 25 can be disassembled by the fixing nail 37, and the convex polishing disc 9 can be replaced to polish the inner surface of the lens. By means of the above structure, the optical lens can be prevented from cracking due to excessive force of the electric clamping, and at the same time, it can adapt to the adjustment of optical lenses of different sizes and thicknesses for polishing operations.
