Description

Cooling liquid spraying device capable of achieving automatic alignment

Technical Field

Background

The lubrication effect of the cutting fluid in the cutting process can reduce friction between the front cutter surface and the cutting chip and between the rear cutter surface and the processed surface, and form partial lubrication film, thereby reducing cutting force, friction and power consumption, reducing the surface temperature of the friction part of the cutter and the workpiece blank and the cutter abrasion, improving the processing performance of the workpiece material, accelerating the processing efficiency and improving the processing quality. The cutting fluid has good cleaning effect, and can remove generated cuttings, abrasive dust, iron powder, oil stain and sand grains, prevent the machine tool, a workpiece and a cutter from being stained, keep the cutting edge of the cutter or the grinding wheel sharp, and not affect the cutting effect.

The cutting fluid is typically sprayed between the workpiece and the machining tool by a conduit. Because the requirements of the workpieces are that the lengths of the machining selection cutters are inconsistent, the guide pipes are required to be adjusted manually frequently, so that the sprayed cutting fluid is positioned between the workpieces and the machining, and the spraying has certain pressure, and in the adjustment process, the cutting fluid is very likely not sprayed or splashed out due to poor adjustment of the angles of the guide pipes. If the spraying is not effective, the tool wear is accelerated, and the machining indicates that surface scratches and the like may be caused by the residual cutting material. Therefore, there is a need for an automatic tool setting cutting fluid injection apparatus that automatically aligns the nozzle with the cutting edge of the tool after the tool change. In addition, the space at the spindle box is small, and the cutting fluid injection device is required to have a small volume.
