A CNC milling machine that is convenient for vacuuming

Abstract

The present application relates to a numerically controlled milling machine that is convenient for vacuuming, which includes a machine body, a drive shaft and a fixing mechanism, the drive shaft is rotatably connected to the machine body, and the fixing mechanism is arranged at the end of the drive shaft away from the machine body, and also includes a suction A dust collection mechanism and a collection mechanism, the dust suction mechanism includes a dust suction cylinder, a fixed ring and a number of fan blades, the dust suction cylinder cover is arranged on the peripheral side of the drive shaft, and the end of the dust suction cylinder is far away from the fixing mechanism It is fixedly connected with the body, the fixed ring is coaxially connected to one end of the drive shaft close to the fixing mechanism, the fixed ring is located in the dust suction tube, and several of the fan blades are arranged along the circumferential direction of the fixed ring Evenly distributed around the fixed ring, the bottom of the end of the dust suction tube away from the fixed ring is provided with a dust removal port, and the collection mechanism is arranged at the dust removal port to collect the dust in the dust suction tube. The application has the effect of facilitating the treatment of dust generated during processing.

Description

technical field [0001] The present application relates to the technical field of milling machines, in particular to a numerically controlled milling machine that is convenient for dust collection. Background technique [0002] Milling machines mainly refer to machine tools that use milling cutters to process various surfaces of workpieces. Usually the milling cutter is mainly moved by the rotation movement, and the movement of the workpiece and the milling cutter is the feed movement. It can process planes, grooves, and various curved surfaces, gears, etc. A milling machine is a machine tool that uses a milling cutter to mill a workpiece. In addition to milling planes, grooves, gear teeth, threads and spline shafts, milling machines can also process more complex profiles, with higher efficiency than planers, and are widely used in machinery manufacturing and repair departments. [0003] The Chinese invention patent application number 201610292065.7 discloses a brake camsh...
