The specific shape of the fixture frame 2 is as follows Figure 4 As shown, the lifting cylinder 6 is arranged on the lower side of the top surface of the jig frame 2, and the connection between the lifting cylinder 6 and the jig frame 2 is sealed. The output end of the lifting cylinder 6 can be retracted into the through hole at the top of the jig base 3, so it will not affect the coordination between the workpiece and the jig base 3. It is worth noting that the lifting height of the lifting cylinder 6 should be less than the extension height of the fixed cylinder 4, so that the workpiece will not touch the jig cover 5 during the transfer of the workpiece by the lever frame 73. The setting position and number of the lifting cylinder 6 can be adaptively adjusted, as long as the lifting cylinder 6 is working, the workpiece after the processing on the top of the jig base 3 can be lifted smoothly. When in use, after the workpiece is processed, the lifting cylinder 6 is started to lift the workpiece. At this time, the servo motor 71 is started to drive the lever frame 73 to move, so that the lever frame 73 transfers the workpiece to the top of the base 72 and moves step by step. Preferably, the output end of the lifting cylinder 6 is provided with a lifting seat 61 that matches the bottom surface of the workpiece.

In this embodiment, the specific shapes and positions of the shaft column 75, the rotating rod 76 and the rotating rod 77 are as shown in FIG. Figure 7 、 Figure 8As shown. When in use, the servo motor 71 is started, driving the rotating shaft column 75 to rotate, thereby causing the rotating rod 76 to perform a circular motion with the rotating shaft column 75 as the center, and then driving the connected lever frame 73 to perform a circular motion. In this process, the lever frame 73 will lift and take away the workpiece lifted by the lifting cylinder 6. As the lever frame 73 continues to perform a circular motion, the lever frame 73 will enter the lever groove 74 and place the workpiece on the top of the base 72. When the lever frame 73 performs a circular motion next time, it will continue to move the workpiece away from the fixture base 3. Preferably, a plurality of lever blocks for limiting and moving the workpiece are provided on the top of the lever frame 73.

[0042] First, start the fixed cylinder 4 to open the jig cover 5, place the workpiece to be processed on the top of the jig base 3, and place it according to the positioning of the jig base 3. After the product is positioned in the jig, start the fixed cylinder 4 again to press the jig cover 5 down to close it. After the jig cover 5 is closed in place, the machine tool starts to process the workpiece;

[0043] Secondly, after the workpiece is processed, the fixed cylinder 4 is started to open the fixture cover 5, the lifting cylinder 6 is started to lift the workpiece, and then the servo motor 71 is started. The servo motor 71 drives the rotating shaft column 75 to rotate, so that the rotating rod 76 performs a circular motion with the rotating shaft column 75 as the center, and then drives the connected lever frame 73 to perform a circular motion. In this process, the lever frame 73 will lift and take away the workpiece lifted by the lifting cylinder 6. As the lever frame 73 continues to perform a circular motion, the lever frame 73 will enter the lever groove 74 and place the workpiece on the top of the base 72. When the lever frame 73 performs a circular motion next time, it will continue to move the workpiece away from the fixture base 3. Repeating the above steps can realize automatic and continuous processing of the workpiece.
