Problems solved by technology

The disadvantage of this structure is: the through holes on the clamping claw and the base claw reduce the thickness of the clamping part, reduce the strength, and easily generate stress concentration. Therefore, under the condition that the blade clamping groove can provide sufficient clamping force, It is easy to cause the clamping part of the tool holder to deform or even break, which leaves hidden dangers for actual production
Although this structure has a certain effect on improving stress concentration, due to the short arm of force, it is very laborious to use, which may lead to deformation of the wrench; at the same time, due to the existence of the keyway, the strength of the clamping part of the tool holder is weakened, which may cause Deformation of the clamping part of the tool holder

Abstract

The invention discloses a toolholder which can be controlled to open and close by a fixing fork spanner and the invention includes a toolholder body. The toolholder body is divided into a neck part, an upper clamping part and a lower supporting part. The neck part, the upper clamping part and the lower supporting part enclose a slot body. The slot body is divided into a blade clamping section and an extending section extended to the neck part. The lower supporting part is provided with a supporting slot that can be cooperated with a supporting fork of the fixing fork spanner. A cut of the supporting slot is arranged at the joint location of the blade clamping section and the extending section. The upper surface of the extending section can keep contact with a rotary fork of the fixing fork spanner to drive the upper clamping part opposite to an elastically rotary supporting surface of the neck part. The toolholder which can be controlled by a fixing fork spanner has the advantages of high intensity of component, convenient for fast blade disassembling and assembling, being able to improve the processing efficiency and reducing the manufacture cost.

Description

technical field [0001] The invention relates to the technical field of metal cutting, in particular to a tool holder whose opening and closing can be controlled by a fixed fork wrench. Background technique [0002] In the metal turning industry, it is often encountered that it is necessary to turn narrow grooves in the workpiece or to cut off the workpiece. The metal cutting tools used for such work are usually made of more expensive hard materials. In order to save cost, the tool is made of blade and tool holder. The blade is made of hard material, has a cutting edge and a certain installation and positioning structure, and can be installed and fixed by the clamping force provided by the elasticity of the tool holder itself. When the cutting edge is worn, the insert can be removed from the holder and replaced with another insert to continue cutting. In cutting processing, reducing processing auxiliary time is one of the effective ways to improve processing efficiency and r...
