Description

technical field [0001] The invention relates to the technical field of metal cutting, in particular to a multi-station cutting machine tool for irregular curved metal. Background technique [0002] Cutting is the use of the relative movement of the cutting tool and the workpiece to remove the excess metal layer from the blank (casting, forging, profile, etc.) to obtain a machine part with dimensional accuracy, shape and position accuracy, and surface quality that fully meets the requirements of the drawing. . Most of the blanks processed by casting, forging, and welding are parts blanks, which are rarely used directly on the machine, and further cutting processing is required to meet the technical requirements of the parts. Cutting machine tools are common tools in metal cutting. [0003] The existing patent (publication number is CN105127450A) discloses a high-speed cutting processing device, which includes a tool table and a cutting device placed on one side of the tool t...

Problems solved by technology

Although multiple turning tools can work at the same time, but the multiple turning tools are fixed, and the processing of irregular curved surfaces cannot be realized.

[0004] In the process of realizing the present invention, the inventor found the following problems in the prior art: cutting machine tools generally can only clamp and process regular metal parts, and it is difficult to clamp metals with irregular curved surfaces, resulting in irregular curved surfaces During the metal processing process, it is easy to loosen and fall off, which reduces the processing effect of irregular curved metal. At the same time, the overall flexibility of the cutting machine tool is low, and it is difficult to cut the irregular curved metal in all directions, and the cutting machine tool can only Single-station processing reduces overall cutting efficiency

In addition, in the prior art, for the three-dimensional curved surface cutting process of the workpiece in the cutting process, the three-dimensional linear motion of the workpiece or the three-dimensional linear motion of the cutting tool is required to cooperate with the multi-axis rotation of the cutting tool, so the driving structure is complicated. , and it is necessary to use complex optical detection equipment and high-speed computing equipment to calculate the rotation angle of the axis cutter, and then use a high-precision encoder to achieve the target angle rotation to complete surface processing, so the cost of this design is relatively high
