Abstract

The utility model discloses a quick clamping tool for processing thin-walled workpieces. The quick clamping tooling used for processing thin-walled workpieces adjusts the length of an adjusting rod extending into a support frame, thereby adjusting the effect on the sidewall of the workpiece. Whether the workpiece is clamped and fixed is realized from the side wall end of the workpiece, and whether the workpiece is clamped and fixed from the top of the workpiece is realized by whether the pressure block is fixed or not, so as to complete the installation, fixation or removal of the workpiece. Because the force of the adjusting rod does not directly act on the workpiece, but directly acts on the pad, and then transmits it to the workpiece through the pad, so that the pad can be used to protect the workpiece and prevent the workpiece from being damaged and deformed. The force of the adjustment rod can adjust the degree of tightening of the workpiece, which can not only make the force of the workpiece uniform, but also adjust the installation center of the workpiece on the worktable properly, so that it is located at the required position and achieves precise Install.
