Embodiment 1

[0063] Embodiment one of the measuring method: the measurement of the straight-line distance between two points of a workpiece, this embodiment comprises the following steps:

[0064] S310: The user selects the test requirement of "measure the straight-line distance between two points" from the measurement requirement menu on the display screen through the human-computer interaction unit,

[0065] S320: The main control program module 210 obtains the test requirements, and transfers the corresponding linear measurement mathematical model from the neural network motion measurement data processing module 220 to the memory for backup;

[0066] S330: The user controls and drags the robotic arm through the hand-held box, and drags the robotic arm to two selected measurement points of the workpiece to perform sampling operations respectively, so that the two measurement points are in contact with the ruby ​​measuring head, and the end of the ruby ​​measuring head After the pressure ...

Embodiment 2

[0071] Embodiment two of the measuring method: to the measurement of the angle between two line segments, this embodiment comprises the following steps:

[0072] S410: The user selects the test requirement of "measure the angle between two line segments" from the measurement requirement menu on the display screen through the human-computer interaction unit,

[0073] S420: Obtain the test requirement by the main control program module 210, and call the corresponding angle measurement mathematical model between two line segments from the neural network motion measurement data processing module 220 to the memory for backup;

[0074] S430: The user controls and drags the robot through the hand-held box, and drags the ruby ​​probe at the end of the robot to the three measurement points selected by the workpiece to operate respectively, so that the three measurement points are in contact with the ruby ​​probe, and the end of the ruby ​​probe The pressure sensor sends out a pulse sig...

Abstract

The invention provides a brand new numerical control robot multi-coordinate measurement system and measurement method. The brand new numerical control robot multi-coordinate measurement system comprises a six-axis robot with a dragging teaching function, a program control system and a man-machine interaction unit, wherein a ruby measuring head is assembled at the tail end of the robot; a pressuresensor is arranged at the stress end of the ruby measuring head; the robot comprises a robot body and six servo drivers on the robot body; the program control system is used for obtaining the state data of each servo motor of the robot corresponding to different sampling points of the ruby measuring head according to measurement requirements, obtaining a corresponding measurement mathematical model on the basis according to the measurement requirements, and obtaining a final result through measurement and calculation; and the man-machine interaction unit is used for controlling the action of the robot to control the sampling of the ruby measuring head and controlling the program control system to select the measuring requirement. The invention further provides the measurement method. According to the system and the method, the measurement requirements which cannot be realized by a non-regular or traditional frame structure measuring machine can be met.

Description

technical field [0001] The invention relates to the technical field of numerical control measurement, in particular to a brand-new multi-coordinate measurement system and measurement method of a numerical control robot. Background technique [0002] In the field of CNC machining parts measurement technology, the current main measurement method is realized on the traditional frame structure three-coordinate number measuring machine, and the measurement of parts is through the three-dimensional movement of the three-coordinate Movement in three directions), so that the ruby ​​probe on the frame is in contact with the specific surface measurement point of the measured part for sampling, so as to realize the measurement of CNC machining parts. However, for the measurement of more than three-dimensional complex structural parts and space surfaces, the traditional frame structure three-coordinate number measuring machine can no longer meet the measurement requirements of the workp...
