Wire cutting cold saw alloy tool bit tooth shifting mechanism

Abstract

The invention relates to a wire cutting machine tool, in particular to a wire cutting cold saw alloy tool bit tooth shifting mechanism. The mechanism is characterized in that a power cylinder frame and a damping cylinder frame are arranged on a front mounting plate; a left baffle plate and a right baffle plate are arranged at two ends of the front mounting plate; a power cylinder connected with acylinder swing shaft is arranged on the power cylinder frame; a power cylinder Y joint is arranged on the power cylinder; a rotating shaft above the power cylinder Y joint is connected with a tooth shifting head; a damping cylinder connected with the cylinder swing shaft is arranged on the damping cylinder frame; a damping cylinder Y joint is arranged on the damping cylinder; a rotating shaft below the damping cylinder Y joint is connected with a damping cylinder connecting frame; a bottom plate is arranged between the left baffle plate and the right baffle plate; a guide rail and a stop blockare arranged on the bottom plate; and a sliding block is arranged on the guide rail. Through the above arrangement, when a cold saw alloy is processed by wire cutting, the requirements that the wirecutting cold saw alloy tool bit tooth shifting mechanism is simple in structure, convenient to apply, high in repeated positioning accuracy and free of water are met.

Description

technical field [0001] The invention relates to a wire cutting machine tool, in particular to a gear shifting mechanism for a wire cutting cold saw alloy cutter head. [0002] technical background [0003] The processing of the existing cold saw alloy cutter head is done on a special grinding machine, using a two-axis cross slide table to shift the teeth. When grinding the front angle of the cutter head, the cutting volume is large and the grinding wheel wears quickly, so the shape of the grinding wheel needs to be disassembled every day. It is very labor-intensive, and wire cutting replaces grinding to cut the rake angle shape and finish of the cutter head, which meet the technical requirements. However, wire cutting requires a large amount of water and many impurities, and the general space is also small. The rod and servo motor are bulky and afraid of water ingress. Contents of the invention [0004] The object of the present invention is to provide a wire cutting cold ...
