Description
技术领域technical field
本发明涉及一种长度测量工具，具体为一种带测力装置的螺旋测微器。The invention relates to a length measuring tool, in particular to a screw micrometer with a force measuring device.
背景技术Background technique
螺旋测微器又称千分尺，是一种较为精密的长度测量仪器。使用螺旋测微器时，将待测物体(如钢球)置于测微螺杆与测砧之间，旋转测微螺杆使待测物体同时与测微螺杆和测砧接触，然后旋转螺旋测微器尾部的测力装置将待测物体夹紧后读数。我国关于千分尺的国家计量检定规程(JJG21-2008)中规定：千分尺的测力应为5—10N。但在实际测量中，测力装置施加力的大小并无显示，因而容易造成对待测物体的夹紧程度不一，由此产生测量误差，并给使用者带来不便。Spiral micrometer, also known as micrometer, is a relatively precise length measuring instrument. When using a screw micrometer, place the object to be measured (such as a steel ball) between the micrometer screw and the anvil, rotate the micrometer screw so that the object to be measured is in contact with the micrometer screw and the anvil at the same time, and then rotate the screw micrometer The force measuring device at the end of the instrument clamps the object to be measured and then reads. my country's national metrology verification regulations on micrometers (JJG21-2008) stipulate that the measuring force of micrometers should be 5-10N. However, in actual measurement, the magnitude of the force exerted by the force measuring device is not displayed, so it is easy to cause different clamping degrees of the object to be measured, resulting in measurement errors and inconvenience to users.

The force-measuring display device is arranged on the bow-shaped ruler frame. The pressure sensor and the force-measuring display device are connected by wires.
所述测力显示装置为液晶屏。The force measurement display device is a liquid crystal screen.
所述测力显示装置为LED灯，当所述压力传感器受到大于等于5N的压力时，输出信号点亮LED灯。The force measuring display device is an LED lamp, and when the pressure sensor is subjected to a pressure greater than or equal to 5N, an output signal lights up the LED lamp.
本发明由于采用上述设计，在测量时，将待测物体夹于测微螺杆和测砧之间，轻轻旋转测力装置，直到测力显示装置显示为5N，或LED灯点亮，提示测量者停止加力，可以读数。本发明有利于准确提供待测物体的夹持力，可用于现有螺旋测微器的改进，提高测量的准确性。Because the present invention adopts the above-mentioned design, during measurement, the object to be measured is sandwiched between the micrometer screw and the anvil, and the force measuring device is gently rotated until the force measuring display device displays 5N, or the LED lamp lights up, prompting the measurement Or stop afterburner, you can read. The invention is beneficial to accurately provide the clamping force of the object to be measured, can be used for the improvement of the existing spiral micrometer, and improves the accuracy of measurement.
