A cylindrical milling cutter capable of quickly changing the milling edge

Abstract

The invention discloses a columnar milling cutter capable of rapidly replacing milling cutter blades, and relates to the technical field of milling cutters. The cylindrical milling cutter that can quickly replace the milling blade includes a fixed milling tool handle, the outer wall of the fixed milling tool handle near the top is fixedly connected with an airflow cooling mechanism, and the outer wall of the airflow cooling mechanism is uniformly provided with a feed knife The inner wall of the feed slot is movably connected with a movable milling cutter, and the outer wall of the movable milling cutter is movably connected with the outer wall of the fixed milling cutter handle through the airflow cooling mechanism provided, and the top of the airflow cooling mechanism is close to the center The position is fixedly connected with a coolant cooling spray mechanism. The cylindrical milling cutter, which can quickly replace the milling cutter blade, cools the milling cutter and the tool holder through the airflow generated during the milling cutter's rotation, preventing the milling cutter from reducing the use of the milling cutter due to high temperature during the milling process. Life situations arise that increase the utility of the device.

Description

Technical field [0001] The present invention relates to the field of milling cutter technology, specifically a column milling cutter that can quickly change the milling blade. Background [0002] A milling cutter is a rotary tool with one or more teeth for milling machining. During the work, each knife tooth cuts the margin of the workpiece intermittently. Milling cutters are mainly used on milling machines for machining planes, steps, grooves, forming surfaces and cutting off workpieces. In order to ensure that a sufficiently high average chip thickness and feed per tooth is used, the number of milling cutter teeth suitable for the operation must be correctly determined. [0003] However, the current market in the milling cutter has a certain deficiency, in the process of use, the milling cutter teeth in turn in the intermittent cutting off the remaining amount of the workpiece, the sharp friction between the knife teeth and the workpiece, so that the knife teeth and the workpie...

AI Technical Summary

Problems solved by technology

[0003] However, the milling cutters currently on the market have certain deficiencies. During use, when the cutter teeth of the milling cutter are intermittently cutting off the allowance of the workpiece, there will be severe friction between the cutter teeth and the workpiece, so that the cutter teeth will come into contact with the workpiece. Huge heat is generated at the place, and the heat is not easy to dissipate. If the temperature is too high, the cutter head will be damaged, which will also reduce the service life of the milling cutter.
