Description

Non-contact optical detector suitable for cutter

Technical Field

The utility model relates to a three-dimensional detector for a cutter, in particular to a non-contact optical detector suitable for the cutter.

Background

The cutting tool is a machined tooth. After the cutting tool is produced, the structure of the cutting tool needs to be measured and detected to determine whether the produced cutting tool meets the design requirements, please refer to CN 110657756.

Currently, there are methods for measuring blade/tool configurations, contact and non-contact measurement methods:

the contact measuring method mainly adopts a profile gauge and a three-coordinate measuring instrument. The contourgraph only forms a simple contour line because the measurement is realized by sliding the contact pin and the surface of the measured tool. The precision measurement of a complex structure cannot be realized, and particularly the accurate coincidence of the contact pin of the measuring tool and the circle center position of a cylindrical hole cannot be ensured by aiming at the geometric center section measurement and the contourgraph of the cylindrical hole of the blade/cutter; the three-coordinate measuring instrument can realize the measurement of a complex structure, but the diameter of the probe influences the size of a concave structure which can be measured by the three-coordinate measuring instrument, the length of the probe influences the depth which can be measured by the three-coordinate measuring instrument, and meanwhile, the measuring mechanism and a measured object often have the problem of space position interference.

Non-contact measurements are based primarily on optics, measuring tool structure without contacting the tool. Among them are projectors, optical electron microscopes and optical profilers. Because the method adopts the technical means of photoelectricity, electromagnetism and the like, in order to obtain the appearance characteristic and the size of a certain structure of the blade/cutter, the photoelectricity or the electromagnetic wave must be capable of contacting the structure without obstacles, and if the structure is complex (the light and the electromagnetism are shielded), the geometrical data information of the structure cannot be accurately obtained, such as: the corresponding data information is difficult to obtain accurately due to the concave structure with deeper depth or more complex structure or smaller size.
