AI Technical Summary

Technical Problem

The existing positioning tungsten carbide end mill assemblies require manual alignment of the clamping groove and the insertion plate for fastening devices. This is prone to loosening during high-speed rotation, increasing installation time and error rate, resulting in high maintenance costs and difficulty in quickly replacing the cutting tools.

Method used

The inclined positioning block is used in conjunction with the inclined positioning groove of the cutting tool to achieve fast and accurate positioning. The positioning block is installed by a detachable bolt connection. Combined with the cooling mechanism and equidistant chip removal groove design, the installation stability and cooling efficiency are improved.

Benefits of technology

It simplifies the installation process, reduces maintenance costs and downtime, improves cutting stability and cooling effect, and expands the versatility and machining accuracy of the cutter head.

Abstract

The application discloses a positioning type tungsten steel milling cutter disc assembly and relates to the field of tungsten steel milling cutter discs. The application comprises a tool shank body, a cutter disc is connected to the outer side of the tool shank body, a plurality of chip removal grooves are formed in the outer surface of the cutter disc, and an installation surface for installing a cutting tool is formed on one side of the chip removal groove; a positioning block is fixedly arranged on the installation surface; the cutting tool comprises a cutting block, positioning grooves are formed in the two side surfaces of the cutting block; the positioning grooves are opposite to the positioning block in position and are used for limiting the position of the cutting tool; two groups of abutting grooves are formed on one side of the installation surface, the abutting grooves abut against the outer side of the cutting tool, the inclined surface positioning block of the installation surface is engaged with the inclined surface positioning groove of the cutting tool, automatic guiding and positioning of the cutting block are realized, the manual adjustment steps are reduced, meanwhile, the two side abutting grooves limit the radial displacement of the cutting tool, resist the lateral cutting force in machining, and the cutting stability is improved.
