Force measurement buffer type height gauge

Abstract

The invention discloses a force measurement buffer type height gauge, and belongs to the field of linear metrology. The force measurement buffer type height gauge comprises a height gauge body and a probe moving plate installed at the left end of the height gauge body. The left end of the probe moving plate is fixedly connected with an extension induction support rod, and the left end of the extension induction support rod is fixedly connected with an inductance buffer connecting block, a spline sliding groove and an inductance buffering cavity located on the upper side of the spline sliding groove are formed in the inductance buffering connecting block, secondary buffering can be carried out on measuring force generated after contact measurement of the measuring pin through a spline sliding column and a flexible telescopic insulation sleeve, and the rigid resistance of the measuring pin is changed by increasing flexible resistance. Therefore, the damage to the measuring pin caused by large resistance impact due to errors is effectively avoided, the deformation quantity of the measuring pin and the probability of disintegration are reduced, the loss of the measuring pin is reduced, the damage to the height gauge body caused by the resistance impact can be effectively reduced, the measurement precision of the height gauge body is effectively ensured, and the accuracy of measured data is improved.

Description

technical field [0001] The invention relates to the field of linear metrology, and more specifically relates to a force-measuring buffer type altimeter. Background technique [0002] Metrology is the use of technology and legal means to achieve unit unity and accurate and reliable measurement of value. In the measurement process, the measuring tools and instruments used are considered to be standard, and they are used to calibrate and verify the tested measuring tools and instruments to measure and ensure the reliability of the measurement results obtained when using the tested measuring tools and instruments for measurement. Measurement involves the definition and conversion of measurement units; the measures, procedures, and legal systems that must be taken to transmit the value and ensure the uniformity of the value. [0003] There are many kinds of measuring instruments, such as gauge blocks, angle gauge blocks, polygonal prisms, sine gauges, calipers, micrometers, dial...

Problems solved by technology

[0004] When the existing altimeter is performing measurement work, the measuring force of the stylus is controlled by its moving speed. If a large error occurs during the measurement process, such as size error, program error, and position error, etc., it is easy to make the height The stylus of the altimeter is impacted by relatively large resistance, which can easily cause the deformation of the stylus, or even cause it to collapse. While reducing its service life, it also reduces the measurement accuracy of the altimeter and affects the accuracy of measurement data.
