Description

TECHNICAL FIELD

[0002] Hardware is a tool made of metal such as gold, silver, copper, iron, and tin, used for fixing, processing, or decorating things.

[0003] For example, a hardware milling device with publication number CN111922402B places the base on the hardware to be processed, the drive drives the milling cutter to rotate, rotates the mounting bracket to make the mounting bracket rotate around the support shaft, and makes the milling cutter rotate around the support shaft to mill a circular arc slot on the surface of the hardware. The drive is placed in different positions in the placement groove, so that the milling cutter has different rotation radii when rotating, and different diameter circular arc slots can be milled. The hardware milling device has the advantages of simple structure, flexible transportation, and simple milling hole and milling slot operation. However, during actual use, when milling hardware, in order to ensure the lubrication and heat dissipation of the cutter and the timely discharge of debris, milling fluid is sprayed during the milling process. When milling an annular groove on the hardware, although milling fluid can be sprayed, when milling annular grooves of different diameters, if the spraying position of the milling fluid does not change, as the annular groove milling angle decreases, the arc angle of the annular groove decreases. At this time, it is not convenient to adjust the included angle between the spraying position and the tangent line at the milling position of the annular groove. When milling a small-diameter annular groove, if the spraying position coincides with the tangent line at the milling position of the annular groove, the spraying of the milling fluid is easily blocked by the workpiece, which causes the milling fluid to not be sprayed at the milling position of the milling cutter in the first time, which causes the heat to not be dissipated in time, which reduces the spraying effect of the milling fluid, and there are certain use defects.
