In addition, lens processing requires turning the lens over and then processing the lens in all aspects. The turning function of common lens processing fixtures needs to be improved. The shapes of lenses are diverse. If the edge of the lens is processed, the fixture needs to be replaced constantly, which increases the cost of lens processing. Therefore, a multi-hole tooling fixture is proposed to address the above problems. Utility Model Content

One end of the spring 1203 is fixedly connected to a fixed column 1204, and the contraction and extension of the fixed column 1204 can realize the function of installing and disassembling the positioning device 12; the total length of the diameter of the connecting arm 1101 and the rotating shaft 1102 is less than the distance between the adjusting column 10 and the limiting plate 6, which facilitates the rotation of the clamp 11 in the clamping state between the limiting plate 6; the upper and lower parts of the limiting plate 6 are detachably connected, which is convenient for installing and disassembling the positioning device 12.
[0027] Working process: The electricity required by the present invention is provided by an external power supply. Remove the upper part of the limit plate 6, lift the protrusion on one side of the fixed column 1204, and the fixed column 1204 moves up. The fixed column 1204 moves up to squeeze the spring 1203, and the spring 1203 contracts to generate elastic potential energy. When the fixed column 1204 is completely retracted into the fixed shell 1202, fit the positioning device shell 1201 with the inner wall of the limit plate 6, loosen the protrusion on one side of the fixed column 1204, and the elastic potential energy of the spring 1203 is converted into elastic force. The spring 1203 bounces the fixed column 1204 into the through-hole of the adjustment column 10, and the lens to be processed is placed in the groove of the positioning device shell 1201, and Use the same method to install the other half of the positioning device housing 1201 in the adjusting column 10, and then place the lens to be processed in the positioning device 12, rotate the rotating shaft 1102 on the single-side connecting arm 1101 of the lens to be processed, the rotation of the rotating shaft 1102 drives the connecting rod 1103 to rotate, the rotation of the connecting rod 1103 drives the suction cup 1104 to rotate, the suction cup 1104 clamps the lens to be processed, install the upper half of the limiting plate 6, rotate the positioning device 12, the rotation of the positioning device 12 drives the adjusting column 10 to rotate, when the positioning device 12 is attached to the inner wall of the limiting plate 6, the lens to be processed and the placement plate 8 are in the same straight line, and the placement table 7 provides a place for the placement plate 8 Height, place the lens mold on the placement plate 8, and clamp the lens mold with the clamp 11. At this time, the lens mold and the lens to be processed are in the same straight line, which is convenient for the operator to observe the lens mold and adjust the processing operation in time. Insert the fixing rod 16 into the through-hole of the limit plate 6 and the adjustment column 10. The fixing rod 16 fixes the position of the processed lens at this moment, and then removes the upper half of the limit plate 6, pulls up the protrusion on one side of the fixing column 1204, and retracts the fixing column 1204 into the fixed shell 1202, thereby disengaging the connection between the fixing column 1204 and the adjustment column 10, thereby facilitating the removal of the positioning device 12, and then clamps the other side of the processed lens with the clamp 11 again. To process the lens and strengthen the fixing effect of the lens, the operator begins to grind the lens with tools. The water in the water storage pot 14 flows into the sprinkler 13 under the action of gravity. The sprinkler 13 sprays water onto the processed lens, cleaning the processed lens while also reducing the temperature of the processed lens. When one side of the processed lens is polished, the processed lens is rotated 180 degrees and the other side of the processed lens is polished.
