Description
Technical field
The present invention relates to a kind of anti-skidding method of drill bit, easily effectively can prevent the anti-skidding straight shank drill of slippage and the convenient anti-skidding taper-shank drill installed from being drilling, cutting cutlery, belong to manual processing and machine tools.
Background technology
The machining of metal and the manual general structure adding the drill bit that man-hour uses have cuts position and installation position, different according to the mounting means of installation position, general drill bit has two large classes, straight shank drill and taper-shank drill, two kinds of drill bits adapt to two kinds of installations respectively: straight shank drill head-clamp is installed and taper hole drill jig sleeve is installed.Drill bit suffered power when cutting can be analyzed to the power of both direction, and one is the rotary cutting power of circumferencial direction, and another is axial cutting propulsive force.The installation position of straight shank drill is cylinder handle, this inadaptability in structure is installed at taper hole drill jig sleeve, the chucking power that drill jig is installed provides the cutting force of circumferencial direction and axial propulsive force, it is stressed when cutting that drill bit just can slippage in clip when being greater than chucking power, the cylinder handle of drill bit can burn out by powerful frictional force, the strengthening layer cutting the cylinder handle surface of drill bit of drill jig meeting one piece a piece, the cylinder shank diameter of drill bit diminishes, the cylinder Bing Shi garden of drill bit, drill bit is made to occur waving, machining accuracy declines, generally for and prevent drill bit slippage in drill bit clip, the clamping force of drill bit clip is strengthened, but the fatigue failure that the clamping force often strengthening drill bit clip can make drill bit clip too early, the spanner of drill bit clip also can be made to damage very soon simultaneously.It is location side's tenon and fixing taper shank that the installation position of taper-shank drill is divided, and this structure is convenient to install at taper hole drill jig sleeve, can provide enough large cutting force and propulsive force, but be not suitable with and install on straight shank drill head-clamp with the change of cutting force.
Summary of the invention
The object of this invention is to provide a kind of convenient installation to prevent the anti-skidding straight shank drill of slippage easily and can either install on taper hole drill jig sleeve and the convenient anti-skidding taper-shank drill installed can be realized on straight shank drill head-clamp, it is by reasonably design, the distance to cylinder handle axial line and the principle of cylinder handle semidiameter with drill bit fixed position on the cylinder handle of drill bit afterbody and drill jig fixed position, the method of drill bit fixed position and drill jig fixed position that the cylinder handle of drill bit afterbody adds makes anti-skidding straight shank drill and anti-skidding taper-shank drill reach clamping easily with effectively anti-skidding, anti-skidding straight shank drill is installed easily on straight shank drill holder, anti-skidding taper-shank drill can realize installing easily on taper hole drill jig sleeve He on straight shank drill holder, this anti-skidding straight shank drill ensures axial precision and rotary cutting power by drill bit fixed position when installing on straight shank drill head-clamp, located by the side's of location tenon when anti-skidding taper-shank drill is installed on taper hole drill jig sleeve, guiding position keeps drill bit shaft to precision, taper shank fixed position ensures rotary cutting power, straight shank drill head-clamp when installing ensure axial precision and rotary cutting power by drill jig fixed position.
This anti-skidding straight shank drill contains drill bit fixed position, cut position, wherein drill bit fixed position is on the cylinder handle of anti-skidding straight shank drill afterbody, the shape of drill bit fixed position meets the clamping needs of straight shank drill head-clamp, anti-skidding taper-shank drill contains the afterbody side of location tenon, guiding position, taper shank fixed position, drill jig fixed position, bit cutting position, wherein the afterbody side of location tenon is at the afterbody of anti-skidding taper-shank drill, the cylinder shank portion with the dead in line of taper shank fixed position is had in the middle of guiding position and taper shank fixed position, guiding position and taper shank fixed position belong to middle containing cylindrical same cone, on the cylinder shank portion of drill jig fixed position in the middle of guiding position and taper shank fixed position, the shape of drill jig fixed position meets the clamping needs of straight shank drill head-clamp equally.
