As shown in Figures 1 to 3, a clamping and forming tooling for thin-walled parts includes a CNC machine tool (not shown in the figure), and at least two fixedly arranged on the CNC machine tool for clamping colored The claw 1 of the metal thin-walled part, and the milling cutter (not shown in the figure) fixed on the CNC machine tool for cutting the non-ferrous metal thin-walled part, the claw 1 matches the milling cutter , the two cooperate to complete the processing and forming of non-ferrous metal thin-walled parts. In this embodiment, there are three jaws 1 in total, which are evenly distributed on the numerical control machine tool, and the three cooperate to complete the fixing of non-ferrous metal thin-walled parts.

The jaw 1 includes a connecting section 11 for connecting and fixing with the CNC machine tool, and a clamping section 12 for clamping non-ferrous metal thin-walled parts, and the connecting section 11 is vertically connected with the clamping section 12 .

The bottom surface of the connecting section 11 is provided with an installation groove 111, the installation groove 111 is matched with the guide slide rail arranged on the numerical control machine tool, and the installation groove 111 is movably arranged in the guide slide rail, so The installation groove 111 cooperates with the guide rail to complete the positioning of the claw 1 .

The connecting section 11 is provided with at least one bolt fixing hole 112 , and the claw 1 is fixedly connected with the numerical control machine tool by means of the bolt fixing hole 112 . In this embodiment, in order to ensure the firmness of the connection, there are two bolt fixing holes 112 . It should be noted that the connection between the claw 1 and the CNC machine tool can also be a mortise and tenon connection or an integrated connection, and the specific connection method can be selected according to actual processing needs.

The side wall of the installation groove 111 is provided with claw teeth 113, the claw teeth 113 mesh with the machine tool teeth on the CNC machine tool, and the claw teeth 113 cooperate with the machine tool teeth to complete The fixing of the jaw 1 prevents the jaw 1 from loosening or slipping due to excessive cutting force during processing, resulting in the problem that the machining accuracy is not up to standard.

The side wall of the clamping section 12 is stepped, including a step 121 for milling cutter feeding, and a clamping step 122 for fixing non-ferrous metal thin-walled parts, the step 121 is higher than the The clamping step 122, the height difference between the knife-feeding step 121 and the clamping step 122 matches the thickness of the side wall of the non-ferrous metal thin-walled part.
