Milling cutter assembly for precision machining

Abstract

The invention relates to the technical field of machine tool machining, and particularly discloses a milling cutter assembly for precision machining. The milling cutter assembly comprises an output shaft, the bottom of the output shaft is fixedly connected with a circular plate, circular cavities are formed in the circular plate at equal intervals in a surrounding mode, openings communicated with the circular cavities are formed in the outer side of the circular plate, a rotating rod is vertically and rotationally installed in the middle of the circular cavities, sliding grooves are formed in the outer side of the rotating rod at equal intervals in a surrounding mode, and sliding blocks are slidably installed in the sliding grooves. Milling cutters with different hardness can be rapidly switched, the requirement for machining workpieces with different hardness can be met, the whole process is simple and easy to operate, time and labor are saved, a mounting frame for mounting the milling cutters can be pushed while the milling cutters are switched, the milling cutters can be pushed out of an opening, and the machining efficiency is improved. And under the condition that the first spring fails due to long-term use and cannot be normally used, normal push-out of the mounting frame can still be ensured, then normal switching is ensured, and the device is worthy of popularization and use.

Description

technical field [0001] The invention belongs to the technical field of machine tool processing, and particularly relates to a milling cutter assembly for precision machining. Background technique [0002] A milling cutter is a rotary tool with one or more teeth for milling. When working, each cutter tooth cuts off the allowance of the workpiece intermittently in turn. Milling cutters are mainly used for machining planes, steps, grooves, forming surfaces and cutting workpieces on milling machines, and for machining planes on horizontal milling machines. The cutter teeth are distributed on the circumference of the milling cutter, and are divided into straight teeth and helical teeth according to the tooth shape. According to the number of teeth, there are two kinds of coarse teeth and fine teeth. The helical-tooth coarse-tooth milling cutter has few teeth, high tooth strength, and large chip space, which is suitable for rough machining; fine-toothed milling cutter is suitab...

Problems solved by technology

[0003] When the existing milling cutter is performing precision machining, it is necessary to frequently replace the milling cutter for workpieces with different hardness so that it can meet the processing needs. The existing milling cutter replacement process is time-consuming and laborious, and multiple milling cutters need to be replaced It takes a lot of time to disassemble the pieces and assemble them one by one, and it also increases the workload of the staff, and may cause the staff to be scratched by the milling cutter, making the work efficiency low
