Referring to fig. 1 to 6, the embodiment of the utility model provides a positioning mechanism of compound lathe handle of a knife 200 of milling machine, including main shaft 100 and handle of a knife 200, handle of a knife 200 and main shaft 100 fixed connection. One side of the main shaft 100 facing the tool holder 200 is provided with a positioning block 110, the positioning block 110 is of a conical structure, the tool holder 200 is provided with a positioning plate 210, and the positioning plate 210 is provided with a first positioning hole 220 matched with the positioning block 110.
Referring to fig. 1 to 6, in particular, the main shaft 100 is provided with a positioning ring 140, and the positioning ring 140 is fixedly connected to the main shaft 100. Wherein the positioning ring 140 is fixedly connected with the main shaft 100 by a second screw. By using a second screw to fixedly attach the retaining ring 140 to the main shaft 100, the connection can be made more stable. The positioning ring 140 is provided with a positioning block 110, and the positioning block 110 is fixedly connected with the positioning ring 140 through a first screw 160. It should be noted that the positioning block 110 and the positioning ring 140 may be connected by a key or a buckle, which may be reasonable according to practical situations by those skilled in the art, and the present invention is not limited thereto. The positioning block 110 includes a fixing portion 120 and a positioning portion 130. The fixing portion 120 is provided with a countersunk hole, the positioning ring 140 is provided with a threaded hole, and the first screw 160 penetrates through the countersunk hole and the threaded hole to be matched, so that the positioning block 110 is fixedly connected with the positioning ring 140.
