[0002] At present, when processing and producing piano string frets, our company installs multiple fixtures for clamping piano string frets 80 on the workbench 12 of the CNC machine tool 10. During production, the piano string frets 80 to be processed are installed on multiple fixtures, and then the CNC machine tool 10 is started for processing. After the processing is completed, the machine is stopped, and the fixture is opened to take out the processed piano string frets 80, and then another piano string fret 80 to be processed is installed, and this is repeated. Since only one is processed each time, and after the piano string frets 80 to be processed are installed on the fixtures and the processing is completed, the processed piano string frets 80 are taken out, during these two processes, the CNC machine tool 10 is in a stopped state, which takes up a lot of time and has low production efficiency.

At this time, the first clamping platform 30 is located below the second clamping platform 40. First, a piano string bridge 80 to be processed is installed on the second clamping platform 40 by the clamp 70. After installation, the second driving device 60 is started to move the second clamping platform 40 to the left reference position of the supporting platform 20 and then stop. Then, the CNC machine tool 10 is started to process the piano string bridge 80 of the second clamping platform 40.

[0041] While the CNC machine tool 10 is processing the piano string weight 80 on the second clamping table 40, the worker is clamping the piano string weight 80 on the first clamping table 30. After the piano string weight 80 on the second clamping table 40 is processed, the processing system 14 moves up, and the second clamping table 40 is driven by the second driving device 60 to move to the right reference position, and the first clamping table 30 is driven by the first driving device 50 to move to the left reference position. At this time, the processing system 14 of the CNC machine tool 10 moves down to process the piano string weight 80 on the first clamping table 30, and the worker disassembles and assembles the piano string weight 80 on the second clamping table 40, and the cycle is repeated.
