The invention relates to a taper-shank slotting cutter grinding device which is controlled by a numerical control system. An X-axis feeding workbench comprises an X-axis guide rail with a grating ruler, and a base, wherein the base is provided with a revolving mechanism; one end of a power shaft of a torque motor in the revolving mechanism is connected with a rotation and angle encoder, and the other end of the power shaft of the torque motor is connected with a taper-shank mounting main shaft; a working taper-shank of a taper-shank slotting cutter can be inserted into the main shaft and synchronously rotates with the main shaft; a Y-axis feeding workbench comprises an upright column and a grinding wheel; the tooth surface outline section of the taper-shank slotting cutter is an involute line; the section of the grinding wheel is a toothed line corresponding to the involute line; a Z-axis feeding workbench comprises a Z-axis guide rail for supporting the upright column, wherein the upright column can move on the Z-axis guide rail. According to the taper-shank slotting cutter grinding device, precise grinding of two symmetric toothed surfaces can be simultaneously finished by once clamping of the taper-shank slotting cutter. During machining, only is the working taper-shank used as a clamping locating reference, so that an abraded cutter can be accurately clamped and located during grinding by the working taper-shank, thus being easily grinded.

Numerical control machine tool used for gear grinding

The utility model discloses a gear grinding machine for precision finishing of a half-cut top gear shaping cutter, comprising a grinding machine body, a dividing device, a grinding wheel lifting carriage, a grinding wheel, a grinding wheel lifting adjusting device, a longitudinal grinding wheel adjusting device, a transverse grinding wheel adjusting device, a grinding wheel major blade finisher, a grinding wheel half-cut top finisher and a grinding wheel lifting displacement measuring device. The gear grinding machine is designed with the half-cut top finisher and the displacement measuring tool on the basis of a Y7125 gear grinding machine according to the principle thereof; the implementation cost is low; as a result, the angle between the chamfering diamond pen of the grinding wheel half-cut top finisher and the side face of the grinding wheel and the load of the chamfering diamond pen in the radial direction of the grinding wheel both can be adjusted according to data; as the involute tooth form of the major blade and the involute tooth form of the half-cut top are ground by two finishers, the intersection points of the tooth forms are clearer; therefore, the time of angle adjustment can be effectively shortened and the production efficiency is improved; and simultaneously, the grinding accuracy of the half-cut top gear shaping cutter can be effectively guaranteed; besides, the gear grinding machine for precision finishing of the half-cut top gear shaping cutter has fine popularization and application prospects.
