Description

Technical Field

[0001] The utility model relates to the technical field of measuring devices, in particular to a high-precision three-coordinate measuring device. Background Art

[0002] The high-precision three-dimensional coordinate measuring device is a precision measuring device used to measure workpieces after machine tool processing. It can directly place the processed workpiece on the measuring table for measurement to evaluate whether the geometric size, shape and surface features of the workpiece meet the design requirements.

[0003] The device usually consists of a measuring table, a probe, a sensor, a controller and software. After the machine tool is processed, the workpiece is transferred to the measuring table, and then the probe and sensor scan or measure each point of the workpiece to obtain its three-dimensional coordinate data. The specific measurement process is as follows:

[0004] Workpiece placement: Place the processed workpiece on the measuring table and fix its position to ensure its stability and accuracy.

[0005] Probe position calibration: The measuring device will automatically or manually move the probe to the reference point for calibration to ensure the accuracy of the probe position and coordinates.

[0006] Measurement: The measuring device scans or measures the workpiece through the measuring head and sensor, and records the geometric information of the workpiece surface. These measurement data can include coordinates, length, angle, curve, surface roughness, etc.

[0007] Data analysis and reporting: The software of the measuring device will analyze and process the measurement data and generate a detailed measurement report. The report can include dimensional deviation, form error, surface shape, flatness, and comparison with design requirements.

[0008] By performing high-precision measurements directly after machine tool processing is completed, the size and shape problems of the workpiece can be detected and corrected in a timely manner, and parts that do not meet the requirements can be prevented from entering the next process, thereby improving production efficiency and product quality. In addition, the measuring device can record historical measurement data for quality traceability and process improvement. When the high-precision three-coordinate measuring device is used, the bracket is not adjustable, resulting in unstable placement of the equipment body, which affects the accuracy of the measurement. In addition, the plug and base of the high-precision three-coordinate measuring device are not stably connected, which can easily cause the body to lose power and cause the body to fail to operate normally.
