A rotary reticle optical magnification measuring device, comprising a light source, a first objective lens group, a second objective lens group, a first reflector, a second reflector, a third reflector, a projection screen, a reticle and a standard rod holder , wherein the light source, the first objective lens group, the first reflector, the second objective lens group, the second reflector, the third reflector and the projection screen sequentially form a projection imaging optical path, and the reticle is arranged on the first reflector and the second reflector. On the optical path between the objective lens groups, the reticle is rotated and positioned on the optical path, and is connected with the handle through the transmission structure. The rotation axis of the reticle coincides with the optical axis; the reticle is provided with a set of graduations for measuring the angle of the blade. A scribe line and a set of radian scribe lines that measure the circular arc of the blade. This solution solves the problem that in the prior art, the reticle is only engraved with cross lines or rice lines, and the reticle is fixed in the mirror box, which cannot meet the requirements of high-precision measurement.
Description
technical field [0001] The invention relates to an optical projection type tool presetter, in particular to a rotary reticle optical magnification measuring device used in the tool presetter, which belongs to the measuring equipment characterized by adopting optical measurement. Background technique [0002] In CNC machining, the radial (diameter) and axial (length) dimensions of various tools used should be pre-adjusted according to programming requirements, and this pre-adjustment requires extremely high precision and is time-consuming. In order to improve the machine time utilization rate of CNC machine tools, usually this kind of pre-adjustment is carried out outside the machine, and a tool presetter is required at this time. The tool presetter is mainly used to measure the coordinate position of the cutting edge of the tool used in the CNC machine tool, machining center and flexible manufacturing unit. Efficiency, high precision and repeatability. [0003] As far as t...
