Abstract

The utility model provides a mechanically-clamped blade type slotting knife, relates to a slotting knife and aims to solve the problems that as a knife for the existing gear slotting machine adopts an integral structure, when the knife can not be ground or a knife edge is broken, the knife has to be discarded; and the knife is high in use expense and serious in resource waste. The slotting knife comprises a knife bar, a blade and a fastening screw. A blade positioning slot is arranged in the front end surface of the knife bar along the radial direction and is matched with a knife handle; a fastening screw through hole is arranged in the middle part of the knife handle; a threaded hole is arranged in the bottom end of the blade positioning slot along the radial direction; the fastening screw is connected with the threaded hole through the fastening screw through hole; and the blade is fastened in the blade positioning slot. The mechanically-clamped blade type slotting knife is a universal knife for a gear slotting machine.

Description

A kind of clamped cutting bit chip slotting tool

Technical field

The utility model relates to a kind of slotting tool, is specifically related to a kind of slotting tool that is installed on the shaping machine.

Background technology

Slotting tool is the universal cutter that shaping machine is used to process all kinds of keyways.At present, the slotting tool that uses on the shaping machine is overall structure, just scraps processing behind reconditioning or the tipping again when cutter, and the cutter consumption costs is high.

The utility model content

The purpose of the utility model provides a kind of clamped cutting bit chip slotting tool, is overall structure to solve the existing used cutter of shaping machine, when cutter is just scrapped processing, the problem that the cutter consumption costs is high behind reconditioning or the tipping again.

The utility model is that the technical scheme that solves the problems of the technologies described above employing is: slotting tool comprises knife bar, blade and holding screw, and said knife bar is a solid hopkinson bar, and said blade is made up of the handle of a knife of processing one and cutter head; The cross section of handle of a knife is a rectangle; The junction of cutter head and handle of a knife is provided with the boss shoulder, radially is processed with the blade locating slot on the front end face of knife bar, and the blade locating slot matches with handle of a knife; The handle of a knife middle part is processed with the holding screw through hole; Be processed with screwed hole on the bottom of blade locating slot vertically, holding screw is connected with screwed hole through the holding screw through hole, with blade tightly in the blade locating slot.

The utlity model has following beneficial effect:

The described a kind of clamped cutting bit chip slotting tool of the utility model, because blade and cutter hub adopt split-type structural, when blade again behind reconditioning or the tipping, a blade that need more renew gets final product, and has solved cutter integral body and has scrapped situation, greatly reduces the cost of use of cutter.But also can be according to the material of different processing components, different machining states, the preferred blade material improves machining status.
