The dovetail type indexing mechanism comprises a base, a rotary disc, a lead screw nut, an indexing lead screw, a sleeve and a hand wheel assembly; the base is a dovetail type female die,the rotary disc is a dovetail type male die, the base and the rotary disc form an arc-shaped sliding rail pair, the rotary disc rotates on the base through the indexing lead screw, and the rotating angle is controlled through a positioning plug pin assembly and an indexing hole in the base. According to the invention, the machining problem of the special-shaped ring member is solved, the part position and size precision requirements are met, and the working efficiency is improved; meanwhile, the defect that the indexing center must be located at the arc center during large-diameter indexing isovercome, the size of the corresponding tool is reduced, the manufacturing cost of the tool is reduced, the manufacturing period of the tool is shortened, and the tool has very high reference significance for similar parts and has very good generalization performance.

New type tilting mechanism of five-axis numerical control non-metallic material-dedicated machine tool
The invention provides a new type tilting mechanism of a five-axis numerical control non-metallic material-dedicated machine tool. The new type tilting mechanism of the five-axis numerical control non-metallic material-dedicated machine tool comprises a fixed frame, a grinding head mounting bracket fixedly connected with the fixed frame, and a grinding head connected with the grinding head mounting bracket, wherein a servo motor is arranged on the fixed frame; a synchronous belt is arranged between the servo motor and the grinding head; the servo motor drives the grinding head through the synchronous belt. By applying the new type tilting mechanism of the five-axis numerical control non-metallic material-dedicated machine tool, the grinding head is driven through the synchronous belt, clamping for many times is avoided, the tilting mechanism can be used for more sophisticated operations, the tilting head has a simple structure, and is convenient to use and maintain, the original cutting tool of a four-axis numerical control carving machine can be replaced, and the four-axis numerical control carving machine can be converted into a five-axis numerical control engraving machine.
