The positioning plate 18 is inserted into the bolt 15. The positioning plate 18 presses the third spring 17 downward and fits on the corresponding two fixing plates 6. The nut 19 is threadedly mounted on one end of the bolt 15. The nut 19 overlaps the positioning plate 18. As the nut 19 is continuously screwed downward, the positioning plate 18 exerts a force on the third spring 17, causing the third spring 17 to deform and compress under the force. As the positioning plate 18 continuously moves downward, the two adjacent workpieces are pressed and fixed synchronously.

[0021] Furthermore, the fixed plate 6 and the second limiting plate 14 are both arranged in an L-shaped structure, and the first limiting plate 11 and the second limiting plate 14 are respectively attached to the inner wall of the fixed plate 6, so as to clamp the workpiece between the first limiting plate 11, the second limiting plate 14 and the fixed plate 6, thereby limiting the workpiece and facilitating the subsequent positioning plate 18 to continuously move downward and synchronously press and fix the two adjacent workpieces.

[0022] Furthermore, the number of the positioning plates 18 is set to three, and the three positioning plates 18 are arranged equidistantly. By adjusting the three positioning plates 18, six workpieces can be pressed and fixed synchronously, thereby improving the processing efficiency of the vertical machining center fixture.

[0023] During use: During the machining process of the vertical machining center, when multiple workpieces need to be clamped and fixed, the worker simultaneously adjusts the first limit plate 11 and the second limit plate 14 outward to make the first movable block 9 and the second movable block 12 slide in the first movable groove 7 and the second movable groove 8 respectively, so that the first spring 10 and the second spring 13 are deformed and compressed by force, and then the workpiece is placed on the bottom plate 5, and the first limit plate 11 and the second limit plate 14 are loosened, and the workpiece is clamped between the first limit plate 11, the second limit plate 14 and the fixed plate 6 under the elastic force of the first spring 10 and the second spring 13, respectively, to limit the workpiece, and repeat the operation to fix the remaining workpieces. The parts are clamped on the corresponding base plate 5, and then the bolt 15 is adjusted to move in the installation groove 4. When it is in the appropriate position, the positioning plate 18 is inserted into the bolt 15. At this time, the positioning plate 18 is overlapped on the third spring 17, and the nut 19 is threadedly installed on the bolt 15 and fits on the positioning plate 18. As the nut 19 is continuously screwed downward, the positioning plate 18 exerts a force on the third spring 17, so that the third spring 17 is deformed and compressed under the force. As the positioning plate 18 continuously moves downward, the two adjacent workpieces are pressed and fixed synchronously. Repeat the operation. By adjusting the three positioning plates 18, six workpieces can be pressed and fixed synchronously, thereby improving the processing efficiency of the vertical machining center fixture.
