Description

Screw thread cutter of multi-functional cutter arbor Technical Field The utility model relates to the technical field of thread cutters, in particular to a thread cutter of a multifunctional cutter bar. Background In the field of machining, thread machining is a common and vital process, and is widely applied to manufacturing of various mechanical parts, and in order to meet machining requirements under different thread specifications, machining depths and complex working conditions, the design and performance optimization of a thread cutter and a matched cutter bar thereof are always important points of industrial research. The cutter arbor that generally uses in the market at present, its mode of connection with screw thread cutter adopts traditional fixed knot to construct more, for example through modes such as interference fit, key connection or simple screw fastening, and these modes of connection can guarantee the stability of being connected between cutter and the cutter arbor to a certain extent, but when need change the cutter in order to adapt to different processing tasks, nevertheless brought very big inconvenience. Disclosure of utility model The utility model aims to solve the technical problem that in the prior art, a cutter head cannot be quickly replaced according to different machining conditions, and therefore, a screw thread cutter of a multifunctional cutter bar is provided. In order to achieve the purpose, the multifunctional cutter bar is characterized by comprising a cutter bar body, wherein an inner groove is formed in the cutter bar body, a rotating column is rotatably connected in the inner groove, a threaded cutter body is arranged in the rotating column, adjusting grooves are formed in two sides of the rotating column, a pushing block is slidably connected in the adjusting grooves, an inserting rod is fixedly connected to one side, close to the adjusting grooves, of the pushing block, arc blocks are fixedly connected to two sides of the inner groove, and a plurality of slots are formed in two sides of the threaded cutter body. Preferably, the inner wall of the inner groove is provided with two annular grooves, the outer diameter surface of the rotary column is fixedly connected with two annular blocks, and the surfaces of the annular blocks are in sliding connection with the inner parts of the annular grooves.
