[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0020] The utility model provides a technical solution: Figures 1-4 As shown, in the present embodiment, a vertical machining center for preventing a workpiece from loosening comprises a base plate 1, a vertical plate 2 and a support box 6 are fixedly connected to the top of the base plate 1, a processing table 5 is fixedly connected to the top of the support box 6, two clamping plates 4 are arranged on the top of the processing table 5, a clamping assembly is arranged on the top of the base plate 1, the clamping assembly is used to drive the two clamping plates 4 to move, an inflatable bag 11 is installed on the side of the two clamping plates 4 close to each other, an inflatable fan 12 is fixedly installed on the side of the clamping plate 4 away from the inflatable bag 11, the output end of the inflatable fan 12 is fixedly connected to the inflatable bag 11, a mounting plate 3 is fixedly connected to one side of the vertical plate 2, an electric cylinder 18 is fixedly installed on the top of the mounting plate 3, and the output end of the electric cylinder 18 passes through the mounting plate 3 and is fixedly connected to a lower pressure plate 19.

[0021] When processing a workpiece, first place the workpiece to be processed on the processing table 5, then use the clamping assembly to drive the two clamping plates 4 to move to the two sides of the workpiece and contact it, and then use the inflation fan 12 to output air to the inside of the inflation bag 11, so that the inflation bag 11 expands and fits tightly with the outside of the workpiece. At the same time, the electric cylinder 18 pushes the lower pressure plate 19 to move toward the top of the workpiece and resist, further enhancing the stability of the workpiece. This series of operations effectively prevents the workpiece from loosening during the processing, thereby ensuring the accuracy of the processing.

While the bidirectional lead screw 8 is rotating, the two special-shaped displacement plates 9 threadedly connected to the outside thereof will simultaneously push the clamping plate 4 towards the workpiece and come into contact therewith, thus facilitating the completion of the fastening work of the workpiece by the clamping plate 4 in cooperation with the air inflation bag 11, making the workpiece more stable during the processing and preventing the workpiece from loosening due to external influences.
