Problems solved by technology
The very important parameter for triangular diamond tools is the tool angle. At present, the methods for measuring the angle mainly include non-contact optical methods such as universal tool microscope, super depth-of-field microscope, and measurement projector. , there is an error in the measured angle, which leads to the problem that the measured value is different each time
In addition, the existing methods mainly rely on manually selecting the outer contour of the tool for measurement, which will inevitably introduce human error

Embodiment Construction
[0019] The system structure of the present invention is as figure 1 As shown, the backlight board, magnifying lens and camera are fixed on the same bracket to form the overall structure of the collection device and placed on the lifting platform, the optical axis of the collection device is perpendicular to the axis of the lifting platform. The focal length and magnification of the magnifying lens are fixed, so its focusing distance and depth of field range are also determined. A translation platform that can be moved in a small amount is placed on the base of the system, which can perform bidirectional movement from the backlight panel to the lens. The movement axis is parallel to the acquisition device and perpendicular to the axis of the lifting platform. Stack the angle stage and the rotation stage on the translation platform in sequence. The rotation axis of the angle stage is perpendicular to the axis of the lifting platform and the optical axis of the acquisition device...

The invention relates to a high accurate automatic measuring system for a diamond tool and a method with the system for measuring an angle of a triangle diamond tool. The automatic measuring system includes: a base, a lifting table fixed on the base, an image collecting device, a collecting card, a controller and a computer, wherein the computer is used to control the rotation, contour lines at two sides of the tool in a contour image is picked up in real time, an included angle of the two straight lines are calculated, the tool rotates to a maximum measuring position and a minimum measuring position of the included angle, thereby determining an optimum measuring position of the tool angle, and the solved included angle of the two straight lines at the optimum measuring position is the tool angle.
Description
technical field [0001] The invention belongs to the technical fields of ultra-precision machining, computer vision detection and image testing, and relates to a high-precision automatic measurement system for the angle of a triangular diamond tool. Background technique [0002] Diamond tools are the main tool for ultra-precision cutting. They have good wear resistance, hardness and thermal conductivity, and can be used for single cutting of non-ferrous metals to achieve nano-level roughness surface processing. The triangular diamond tool is an important tool for processing microstructures such as microgrooves and microprisms. Since the microstructure is directly copied on the workpiece by the shape of the tool, the accuracy of the tool parameters is an important indicator to ensure the processing of the microstructure. The very important parameter for the triangular diamond tool is the tool angle. At present, the methods for measuring the angle mainly include non-contact opt...
