Technical Description
1. Host
1.1 Instrument composition
The articulated arm measuring machine is composed of a fixed platform, a magnetic table base (or a suction cup, a tripod), a measuring machine host, a computer and software, and a probe. It must be stably fixed on the platform during measurement (the level is not required, but the relative position of the measuring machine and the workpiece to be measured is required to be stable throughout the measurement process), the main body of the measuring machine is fixed by suction cups or screws, and the portable computer (not limited to) is connected by the USB signal line The host and software complete measurement data acquisition and processing and generate measurement reports.

1.2 Measuring principle
The articulated arm measuring machine consists of three steel arms, six movable joints and a measuring head. Three arms are connected to each other, one of which is a fixed arm, which is installed on any base to support all parts of the measuring machine, and the other two movable arms can move at any position in space to meet the needs of measurement, one of which is the middle arm and the other For the end arm and install the probe on this end. Between the first fixed arm and the second intermediate arm, between the second and third end arms, and between the third and the contact probe, they are all articulated, which can be rotated in space, and each movement The joint is equipped with mutually perpendicular rotation angle sensors, which can measure the position of each arm and probe in space. The rotation center of each joint and the corresponding movable arm constitute a polar coordinate system. The rotation angle, that is, the polar angle, is measured by the sensor. The distance between the rotation centers of the two ends of the movable arm is the length of the polar diameter in polar coordinates. It can be seen that the measurement system is composed of three It is composed of a series of polar coordinate systems. When the probe is in contact with the measured part, the measurement system can give the three-dimensional position information of the probe in space. When the probe and the measured part are in contact at different positions, the measurement system is based on the established measurement. Mathematical model, the actual value of the measured parameter is given by the computer.

4. PowerINSPECT measurement software
PowerINSPECT is a powerful, easy-to-learn and easy-to-use measurement software, which is widely used in various measurement equipment. PoweerINSPECT provides powerful CAD data interface conversion software with a friendly user interface. It performs online inspection and error analysis with a wide-format 3D mathematical model to generate a clear and easy-to-understand inspection report that meets PTB certification and ISO9002 standards.

PowerINSPECT Standard Edition the online measurement system can be used for the measurement and error analysis of precision parts to provide actual measurement basis for product accuracy. The PowerINSPECT standard version is a complete inspection system, which can measure parts in combination with a measuring device. The measuring device can be a traditional coordinate measuring machine, a measuring arm or a non-contact device. The measured data can be compared with the CAD model data to evaluate the quality of the part. It includes the following functions:

1. Perform on-line inspection of precision parts, measure the data of each key position, and compare and analyze with the CAD geometric model (theoretical model). And present the analysis and processing results to users in the form of images, error annotations or analysis reports
2. The PowerINSPECT online measurement system can be used for the measurement and error analysis of complex precision parts, providing actual measurement basis for whether the product accuracy is qualified or not
