This process facilitates the replacement of one set of fixtures, saving material change time and improving the processing efficiency and practicality of the machine tool.

[0024] Working principle: The fixture is inserted into the positioning block 4. The knob 85 is turned to rotate the worm 83. The worm 83 then engages and drives the worm wheel 84 to rotate. This drives the threaded rod 7 to rotate through the connecting rod 81. This, in turn, drives the slider 10 and the clamping plate 5 to move, thus fixing the fixture. When the eyeglass frame blank in one set of fixtures in the processing position is processed, the free end of the hydraulic rod 94 is retracted, which then pulls the linkage block 93 and the rack 92 to move. This engages and drives the gear ring 91 to rotate, which then automatically drives the connecting column 11 and the material plate 3 to rotate. Then, another set of fixtures is positioned in the processing position.
