[0002] The forming cylinder used on a 3D printing device is used to carry metal powder and part forming. As the printing size of the 3D printing device continues to increase, the size of the forming cylinder is also getting larger. The overall forming cylinder workpiece is particularly hard, and the internal cavity processing requirements are very high, without allowing tool jointing. The surface roughness requirement is ≤1.6, and the flatness is ≤0.1. In order to improve the processing efficiency and ensure the product quality, it is necessary to use a 61125 ordinary horizontal lathe combined with a tool combination device to process the forming cylinder. Therefore, it is necessary to fix the forming cylinder on the pallet of the lathe equipment. In order to ensure the internal cavity processing quality of the large forming cylinder, it is necessary to improve the fixing accuracy of the forming cylinder on the pallet of the lathe equipment. For this reason, an external movable tooling dedicated to fixing the forming cylinder on the machine tool is proposed. Content of the Utility Model
