The invention relates to a tool parameter
measurement device based on a CCD and a measurement method of the device.The tool parameter
measurement device comprises a collection box, a CCD industrial camera, an industrial
personal computer and a display, and the CCD industrial camera, the industrial
personal computer and the display are sequentially connected; a camera transverse moving mechanism is arranged on a base of the collection box, a camera longitudinal moving mechanism is arranged on the camera transverse moving mechanism, and the CCD industrial camera is installed on the camera longitudinal moving mechanism.When measurement is conducted, a
machine tool main shaft does not rotate, and static collecting is conducted; the main shaft collects an image whenever the main shaft rotates by one angle, and
peripheral morphology of a tool is collected and stored in the specific location;
data processing is conducted on a collected gray image.According to the tool parameter
measurement device based on the CCD and the measurement method of the device, the tool parameters are directly measured on a
machine tool, tool disassembly is omitted, the precision and efficiency are improved, non-contact measurement is conducted on a
digital image based on the CCD, static measurement is conducted on the tool parameters, and the cost is reduced compared with that of a camera needing automatic focusing under rotation; the parameters such as slack length,
radius, fillet and form and location tolerance of the tool can be measured.
