  • Measuring device
    Patent number: 9212890
    Abstract: A measuring device includes a measuring platform, a length measuring mechanism, a width measuring mechanism, a segment difference measuring mechanism, and a controller. The measuring platform includes a fixing board and a support bracket mounted on the fixing board. The length measuring mechanism is mounted on the fixing board for measuring a length of a workpiece. The width measuring mechanism is mounted on the fixing board for measuring a width of the workpiece. The segment difference measuring mechanism for measuring a segment difference, includes a first measuring assembly and a second measuring assembly. Both the first measuring assembly and second measuring assembly include a sensor, a measuring member movably passing through the sensor, and a driver connected to the measuring member. The controller is electrically connected with the length measuring mechanism, the width measuring mechanism, the sensor of the first measuring assembly, and the sensor of the second measuring assembly.
