Problems solved by technology
[0002] At this stage, the flatness inspection tool of mechanical parts cannot cover the entire plane, and the measurement needs to be divided into multiple operations, which not only consumes too much time and reduces the efficiency, but also increases the human error in the measurement process; while using sensor measurement methods such as laser diffraction Although the measurement efficiency is good, but the cost is high, it is not suitable for on-site measurement, and it is only suitable for the surface with small smoothness. For the surface with large roughness, the measurement result will produce hysteresis error, and the accuracy of flatness and parallelism cannot be guaranteed. Problems in actual testing

The invention discloses a measuring tool for detecting the flatness and parallelism of flat plates. The measuring tool is characterized in that the measuring tool includes a member pressing plate, a dial indicator and a supporting bench; the side parts of the supporting bench are connected to slide guide rails; the slide guide rails are slidingly provided with first guide rail slide blocks; the member pressing plate is parallel to the supporting bench and slidingly connected to the slide guide rails through the first guide rail slide blocks; the member pressing plate is provided with multiplemeasuring holes; the measuring holes are movably provided with measuring pins; the bottom ends of the measuring pins protrude the measuring holes; and the dial indicator is used for detecting the positions of the measuring pins in the measuring holes. The measuring tool can measure the flatness and parallelism of flat plate surfaces with large thicknesses on site, data situations during measuringcan be timely fed back, and therefore, efficiency can be enhanced.
Description
technical field [0001] The invention relates to the field of mechanical industrialization, in particular to a measuring tool for detecting flatness and parallelism of flat plates Background technique [0002] At this stage, the flatness inspection tool of mechanical parts cannot cover the entire plane, and the measurement needs to be divided into multiple operations, which not only consumes too much time and reduces the efficiency, but also increases the human error in the measurement process; while using sensor measurement methods such as laser diffraction Although the measurement efficiency is good, but the cost is high, it is not suitable for on-site measurement, and it is only suitable for the surface with small smoothness. For the surface with large roughness, the measurement result will produce hysteresis error, and the accuracy of flatness and parallelism cannot be guaranteed. There is no problem in actual testing.
