Abstract

The invention provides an in-place detection and positioning device for a diamond cutting tool. The in-place detection and positioning device for the diamond cutting tool comprises an optical bracket, a fine adjustment and locking mechanism, an optical system and an industrial control computer, wherein the fine adjustment and locking mechanism is fixedly arranged on the optical bracket; the optical system is fixedly arranged on an adapter coupling plate of the fine adjustment and locking mechanism, and moves up and down along a sliding rail; the industrial control computer is connected with a CCD (Charge Coupled Device) sensor through a network cable, and is provided with upper computer software for receiving the image data of the CCD sensor and performing data processing. The device can be used for performing in-place detection and positioning on the diamond cutting tool, works independently to detect the diamond cutting tool off line, and is high in system resolution and positioning accuracy, simple in structure and convenient to operate.

Description

technical field [0001] The invention belongs to the field of ultra-precision machining, and in particular relates to a diamond cutter in-position detection and positioning device. Background technique [0002] Diamond tool is an important factor to achieve ultra-precision machining, and the precise determination of its working parameters is a prerequisite for optimizing process parameters and improving machining accuracy. Different from its design parameters, the working parameters of diamond tools must be obtained by in-situ detection on ultra-precision machine tools. In addition, the diamond tool must be accurately installed at the height coincident with the machine tool spindle, and the precise positioning in the horizontal plane can ensure the relative position control of the diamond tool and the machine tool spindle during the machining process, thereby improving the machining accuracy and surface quality. [0003] At present, the LVDT tool setting system is used on fo...
