Multi-edge conic handle cutter bar with flange contact face

Abstract

The invention discloses a multi-edge conic handle cutter bar with a flange contact face. The multi-edge conic handle cutter bar comprises a connecting bar, a flange plate, a flat key, the contact face, connecting holes, an adjusting bolt, a clamp seat, a conic handle, conic faces and a clamping portion. The multi-edge conic handle cutter bar has the advantages that the connecting bar and the conichandle are each a bar body made of a stainless steel hard alloy material and are designed integrally, and the conic handle cutter bar has high hardness and strength and is prevented from being brokenin the use process; a groove is formed in the front end of the connecting bar, the flat key is inserted in the groove of the connecting bar, torque can be transmitted to a mounted cutter head, and then the cutter head is driven to rotate; antiskid grooves are formed in the contact face and are located between the adjacent connecting holes correspondingly, friction force between the flange plate and the cutter head is increased, and then large axial loads can be borne; and the conic handle is provided with the eight conic faces, each conic face is coated with a composite coating, the surface of the conic handle has good high temperature oxidization resistance and wear resistance, and then clamping and fixing are facilitated when the multi-edge conic handle cutter bar and a lathe are mounted.

Description

technical field [0001] The invention relates to a cutter bar, in particular to a polygonal cone shank cutter bar with a flange contact surface, which belongs to the technical field of milling tools. Background technique [0002] In the field of mechanical processing, such as milling machines, boring machines and other mechanical equipment, tool holders are commonly used processing tools. Tools suitable for different processing conditions can be placed on the tool holder. [0003] And for existing tool bar, one, bar body and connection clamping position are welded and fixed, when harder workpiece is processed, its joint is easy to fracture, influences the service life of tool bar, also exists certain simultaneously Potential safety hazards, the second, when connecting with the cutter head, the connection is easy to loose, and then the cutter head cannot be rotated with the cutter rod, which affects the processing quality and processing efficiency of the workpiece, and third,...

Problems solved by technology

[0003] And for existing tool bar, one, bar body and connection clamping position are welded and fixed, when harder workpiece is processed, its joint is easy to fracture, influences the service life of tool bar, also exists certain simultaneously Potential safety hazards, the second, when connecting with the cutter head, the connection is easy to loose, and then the cutter head cannot be rotated with the cutter rod, which affects the processing quality and processing efficiency of the workpiece, and third, the handle of the cutter rod It is clamped and fixed with the lathe, and the handle of the tool holder is easily damaged by a large clamping force, so it cannot be clamped multiple times
