Embodiment Construction

[0023] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0024] figure 1 It is the working principle diagram of the embodiment of the present invention. figure 1 In the process, the diamond tool to be tested is installed on the centering device, and the centering device is installed on the front end of the ultra-precision rotary shaft system. The diamond tool rotates at a specific angle smoothly under the drive of the ultra-precision rotary shaft system. The atomic force microscope is used to measure the height change data of the flank surface of the diamond tool, and then the measured data is sent to the computer for analysis and graphic display.

[0025] In the measurement system, the eccentric error of the tool installation has a great influence on the ultra-precise detection of the arc waviness of the diamond tool tip. Therefore, it is necessary to design a precision aligning devi...

Abstract

The invention provides an aligning device for the measurement of a diamond cutting tool. The aligning device comprises actuators, a bracket, a mounting plate, ejector heads, springs, spring seats, a stop piece, screws, pre-tightening screws and threaded holes, wherein a connecting mode is as follows: the actuators are fixedly connected to the bracket; the ejector heads are fixedly connected to the bracket; the spring seats are fixedly connected to the bracket; the springs are fixedly connected to the spring seats; the stop piece is fixedly connected to the mounting plate; the mounting plate is fixedly connected to the bracket. The aligning device for the measurement of the diamond cutting tool can be used for realizing the atomic force microscope-based nanometer measurement of waviness of a tool nose arc.

Description

technical field [0001] The invention belongs to the technical field of precision measurement, and in particular relates to a centering device for measuring a diamond tool, which can realize submicron eccentric adjustment of the diamond tool and an ultra-precision rotary shaft system. Background technique [0002] Single point diamond turning (SPDT) technology, as an important branch in the field of ultra-precision machining technology, has huge actual or potential demand in national defense and civilian applications with the development of national needs and future emerging strategic industries. High-precision diamond tools are one of the basic conditions for single-point diamond ultra-precision cutting. The quality of the cutting edge directly affects the surface accuracy and surface quality of the product. Therefore, it is of great significance to carry out quality evaluation of ultra-precision diamond tools. [0003] The edge quality of diamond tools mainly includes sharp...
