Problems solved by technology
[0002] In the prior art, the measurement of the coefficient of static friction mostly needs to provide samples separately, or there are restrictions on the size, quality and position of the measured object, which cannot meet the actual needs
For example: in some engineering sites, it is impossible to measure in time; it is difficult to sample and measure when performing regular static friction coefficient tests on the guide rails of large machine tools in normal use to ensure their accuracy
The hand-held friction coefficient measuring device can basically only be used for the measurement of the measured surface in the horizontal direction, which limits its scope of application

The invention discloses a device and method for measuring static friction coefficient, and belongs to the technical field of material friction measurement. The technical problems that in the prior art, a sample needs to be provided separately for the static friction coefficient measurement, and an measured object is limited in size, mass and position, and a handheld friction coefficient measurement device can only be used for measuring the measured surface in the horizontal direction are solved. The device comprises a push plate, a slide block, a pressing part and a sensing part; the sensing part comprises a first sensor and a second sensor; the push plate comprises a top surface and a side surface, wherein the top surface is in contact with the slide block through the pressing part and the first sensor, and the first sensor is arranged between the pressing part and the slide block; the side surface comprises a first side surface which is in contact with the slide block through the second sensor; the second sensor can collect the lateral external force exerted to the slide block, and the lateral external force is parallel to the measured surface; and the first sensor can collect the longitudinal external force exerted to the slide block, and the longitudinal external force is perpendicular to the measured surface.
Description
technical field [0001] The invention relates to a static friction coefficient measuring device and method, belonging to the technical field of material friction measurement. Background technique [0002] In the prior art, the measurement of the coefficient of static friction mostly needs to provide samples separately, or there are restrictions on the size, quality and position of the measured object, which cannot meet the actual needs. For example: in some engineering sites, it is impossible to measure in time; it is difficult to sample and measure when performing regular static friction coefficient tests on the guide rails of large machine tools in normal use to ensure their accuracy. The hand-held friction coefficient measuring device can basically only be used for measuring the surface to be measured in the horizontal direction, which limits its scope of application. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentio...
