Description

Image measuring tool device

technical field

The utility model relates to the field of photoelectric measurement, in particular to an image measuring tool device.

Background technique

When measuring tools in professional tool manufacturers and tool grinding factories, it is necessary to measure the diameter, length, cutting edge spacing, rake angle, back angle, helix angle, main declination angle, secondary declination angle and other dimensions of the tool. Measure precisely. When the ordinary image measuring instrument measures the tool, it needs to clamp the tool multiple times to meet the dimensional measurement of the above multiple angles. The error caused by the clamping cannot be avoided by multiple clamping. The diameter measurement technology is mostly manually measured by mechanical or electronic vernier calipers, and the efficiency of this manual measurement method is low.

At present, there are still some two-dimensional tool measuring instruments. Taking the tool setting instrument produced by Tianjin Tianmen Precision Machinery Co., Ltd. as an example, it is composed of a sensor system and a mechanical system. The sensor includes a CCD camera and a linear grating ruler; the mechanical system includes two linear motions and one rotary motion, all of which are manually adjusted. When measuring, install the tool on the spindle, observe the tool image presented by the projection screen or CCD with human eyes, manually adjust the tool to the best measurement position, record the two-dimensional position coordinates (x, y) with the grating ruler, and analyze it through software , Calculate the measurement results. It can only measure the geometric parameters of the second-line plane. Due to the limitations of the mechanical system, sensors and measurement software functions, the measurement function and accuracy are very limited. For some special angles such as tools: rake angle, relief angle, helix angle, leading angle , secondary deflection angle, tooth pitch, core thickness, chisel edge, backlash angle, axial and radial runout, etc., it is still impossible to detect accurate data. For tool design, the tool manufacturing industry still cannot meet the demand.
