Abstract
The utility model particularly relates to a special fixture in grinding a spiral milling cutter blade, which is mainly used for clamping a milling cutter when in the grinding for the spiral milling cutter by a grinding machine. The special fixture consists of a taper core rod, a sleeve and a locking nut, wherein the two tips of the taper core rod are provided with central holes; one end of the taper core rod is provided with a limit platform, and the other end thereof is provided with external screw thread; the sleeve is sheathed on the taper core rod; and the locking nut is arranged on the external screw thread. The special fixture is used in a method that the milling cutter is sheathed on the taper core rod, the sleeve push against the milling cutter tightly, and the locking nut is screwed tightly; the two top tips of the grinding machine push against the taper core rod, a hand holds the taper core rod to rotate at a constant speed, a grinding wheel grinds the milling cutter blade repeatedly, and the polished milling cutter can be used continuously, so as to prolong the service life of the milling cutter and lower the processing cost.
Description
Technical field:
Clamping milling cutter when the utility model is mainly used in grinding machine spirality milling cutter is specifically related to spirality milling cutter edge grinding special fixture.
Background technology:
0.5 the thin plate sheet material of～3mm adopts the spirality milling cutter to process, in the process, mechanical wear and thermal wear can appear in blade, make milling cutter can not continue to use, because it is do not have special-purpose clamping device, milling cutter can't carry out sharpening on grinding machine, general just by scrapping processing.
Summary of the invention:
In order to cut down finished cost, prolong the service life of milling cutter, the utility model provides a kind of spirality milling cutter edge grinding special fixture.
The utility model is made up of conic mandrel bar, sleeve pipe and locking nut that two terminations are equipped with centre bore, and an end of conic mandrel bar is provided with limiting stand, and the other end is provided with external screw thread, and casing pipe sleeve is on conic mandrel bar, and locking nut is arranged on the external screw thread.
Utilize the utility model that milling cutter is clamped, can on grinding machine, carry out sharpening.
Using method of the present utility model is: milling cutter is enclosed within on the conic mandrel bar, and sleeve pipe holds out against milling cutter, tightens locking nut.Two top conic mandrel bars that withstand with grinding machine grasp conic mandrel bar and at the uniform velocity rotate, and emery wheel is the blade of grinding milling cutter repeatedly, and the milling cutter that reconditioning is good can continue to use.Thereby prolonged the service life of milling cutter, reduced processing cost.
Description of drawings:
Fig. 1 is the front view of the utility model embodiment.
Among the figure: 1, conic mandrel bar 2, limiting stand 3, sleeve pipe 4, locking nut
