Device for machining U-shaped-structure heating body

The invention discloses a device for machining a U-shaped-structure heating body. The device comprises a numerical control machine tool and a tool, wherein the numerical control machine tool is used for continuously machining the U-shaped-structure heating body., and the tool is arranged on a machining table of the numerical control machine tool. The tool comprises a base, a U-shaped supporting part, a clamping part and a tightness adjusting component, wherein the U-shaped supporting part is arranged on the base, and the outer side face of the U-shaped supporting part is used for supporting the U-shaped-structure heating body; the clamping part is arranged on the outer side face of the U-shaped supporting part, and a clearance for containing the U-shaped-structure heating body is arranged between the clamping part and the U-shaped supporting part; and the tightness adjusting component is used for adjusting the size of the clearance. By the adoption of the tool, overall fixation of the U-shaped-structure heating body to be machined can be achieved. Therefore, the numerical control machine tool can be adopted to take one linear segment as the starting point and the other linear segment as the end; and the U-shaped-structure heating body is continuously machined, so that the problem that when segmentation machining is adopted, the linear segments and a transition area of an arc segment are not continuous is solved.
