Embodiment Construction

[0016] The present invention will be described in further detail below in conjunction with embodiment.

[0017] The invention is designed according to the working requirements of the quasi-ball milling method in which the ball and the sample reciprocate and vibrate along the axial direction of the cylinder. According to the requirements of control accuracy and performance, refer to figure 1 , the control system of the strength impact instrument of the present invention includes a man-machine dialogue interface system, a PLC controller, a servo driver, a servo motor, and a reciprocating impact mechanism, and the reciprocating impact mechanism drives the charging cylinder to perform a corresponding reciprocating impact movement, thereby measuring Impact strength of superhard materials.

[0018] Among them, the human-machine dialogue interface system is used as the upper computer, and communicates with the PLC controller through the 232 serial port data line. Accurate correspon...

Abstract

The invention provides a cBN / diamond strength impact instrument control system. The system is suitable for testing impact strength performance index of diamond and cBN abrasive materials. The controlsystem is suitable for testing the impact strength of various grades of ultrahard abrasive materials. The system adopts a PLC as a control unit, controls rotation of a servo motor and reciprocating motion of a reciprocating impact mechanical device and fulfills the aim of measuring the impact strength of the ultrahard material. A threshold photoelectric induction protection device is arranged at the charging opening of a charging cylinder and is used for protecting the working state of the charging cylinder; meanwhile, a counting photoelectric induction device is arranged on the mechanical rotation part of the reciprocating impact mechanical device and is used for accurately counting. The control system accurately controls the impact times and the working state of the reciprocating mechanical device in the impact process and replaces a singlechip by using the PLC controller to realize the stable test state.

Description

technical field [0001] The invention belongs to a cBN / diamond impact strength testing system, and in particular relates to the technical field of testing cBN / diamond impact strength. Background technique [0002] Superabrasives are subjected to two effects of impact and friction during use, and their quality is closely related to the ability to withstand these two effects. During the use of superabrasives, the quantitative testing of their impact properties is very important. The measurement system of the imported diamond impact instrument is controlled by a single-chip microcomputer, and the control command program and peripheral interface circuits are integrated on the control circuit board. During the working process, the control program instructions solidified inside the single-chip microcomputer chip on the control circuit board are sent to the peripheral interface, and then pulses are sent to the stepping motor through the stepping motor driver, and the stepping motor...
