Taper-shank slotting cutter grinding device

Abstract

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.

Description

technical field [0001] The invention belongs to a numerical control processing device, in particular to a numerical control grinding and forming device for a cutting tool, in particular to a grinding device for a tapered shank gear shaper cutter. Background technique [0002] At present, "Y7125 gear grinder" is regarded as the best grinder for grinding tapered shank gear shaper cutters. Most of the existing high-precision tapered shank gear shaper cutters are processed on this kind of grinder. But, there are following three defects in this grinder: [0003] First, it is a grinding machine that uses a large flat grinding wheel to grind the tooth profile on one side. To process a formed tapered shank gear shaper cutter, the cutter blank needs to be turned around and clamped, and the tooth surfaces on both sides are ground separately. Not only that, but also a process taper shank 2 for U-turn clamping is added on the knife blank. The process taper handle 2 is located on the o...

Problems solved by technology

And when the tooth profile surface of the tapered shank gear shaper cutter has been ground, the process taper shank 2 must be cut off. After the process taper shank 2 is removed, a reference point a for accuracy detection and a clamping positioning reference surface are missing, which makes The grinding and testing of the tapered shank gear shaper cutter cannot be carried out, which brings a lot of inconvenience to the production and use of the tapered shank gear shaper cutter

[0004] Second, its involute tooth profile forming mechanism is composed of a cam platen. For the grinding of different specifications of tapered shank gear shaping cutters, the corresponding cam platen needs to be replaced, and the error of the cam platen directly affects the cone The grinding quality of the tooth profile surface of the shank shaper cutter, and this error is difficult to correct
