Description
Technical Field
The invention relates to the field of machining, in particular to a machine tool dust removal main shaft structure and a machine tool dust removal device.
Background
With the continuous development of the technological level, new materials emerge endlessly, and various advanced composite materials are more and more widely applied in the fields such as aerospace, electronics and electrical, automobile manufacturing and the like by virtue of excellent physical and chemical properties of the advanced composite materials.
Since composite materials generally consist of a matrix and a reinforcing phase, machining is brittle, and thus chips generated by machining are powdery, unlike strip-like curled chips in metal machining. Due to high-speed rotation in the machining process of the cutter, powdered cutting scraps can generate large-scale flying and flying dust, the cleanness of a machining environment is influenced, the service life of a machine tool guide rail is influenced, and the health of machine tool operators is also influenced. Therefore, the products such as cutting scraps, dust, slag and the like generated in the composite material cutting process must be effectively treated.
At present, a common treatment method in the machining field is to use an external dust collector to suck and treat dust, fix an air suction port of the dust collector on a main shaft of a machine tool, approach a cutter, suck the cutting dust out of the machine tool through an external pipeline in an air suction dust removal mode and then settle. The closer the air suction port is to the cutter, the better the dust removing effect is, but the possibility of interference between the dust suction pipeline and the workpiece needs to be considered, so the distance cannot be too close, and the dust removing effect is greatly limited. This type of device generally requires the worker to open or close it manually, or to open it all the way through the plant's operation, and therefore its noise pollution and consumption of energy are not negligible.
The method and the device can control the concentration of the cutting dust to a certain degree, but the treatment effect is limited by the factors such as the performance of the dust removal device, the installation position and the angle of the air suction port and the like, and in some processing processes, because the size of the dust suction pipeline is overlarge, the dust suction pipeline can interfere with a workpiece and can only be placed far away from a cutter and a cutting area, and the dust removal effect is greatly reduced. In addition, because the dust collecting equipment installation pipeline needs to be purchased separately, extra electric energy is consumed, and the economic cost is high. Because the dust removal device is opened and closed by manual operation, the dust removal device cannot automatically run along with the starting and stopping of the machine tool, energy waste is caused, the cost is increased, and the dust removal device is expensive and labor-consuming.
