Machining carrier of double-end turning tool

The machining carrier comprises a main shaft, at least two positioning plates arranged at intervals in the axial direction of the main shaft are arranged on the main shaft, four frame rods arranged at equal intervals in the circumferential direction of the main shaft are arranged between the positioning plates, the frame rods and the main shaft are arranged in parallel, and the positioning plates are arranged on the main shaft. A plurality of clamping openings are formed in the frame rods at intervals in the axial direction of the frame rods, the two ends of the double-end turning tool are clamped in the two clamping openings in the two adjacent frame rods respectively, and a fixing component is detachably arranged on the positioning plate and used for pressing the double-end turning tool on the frame rods. According to the machining carrier, the four rows of double-end turning tools can be erected through the four frame rods, the double-end turning tools in each row are distributed at intervals, the number o
