The invention discloses a shaking-preventive grating projector, and belongs to the technical field of measuring devices. The projector comprises a measuring pedestal, U-shaped connecting poles are fixedly mounted in the two sides of the bottom of the measuring pedestal respectively, walking wheels are movably mounted in the inner sides of the U-shaped connecting poles respectively, and an installation hole is formed in the internal of the measuring pedestal. The shaking-preventive grating projector measures the surface morphology of an object, a horizontal installation plate is arranged, a measuring instrument fixed on the horizontal installation plate measures the surface morphology of the object, one end of the horizontal installation plate is movably connected with a U-shaped pedestal,the other end of the horizontal installation plate is connected with a rope, when a servo motor starts to drive a rotating disc to rotate forwardly or backwardly, the rope is tightened or loosened correspondingly, the horizontal installation plate inclines upwardly or downwardly, the inclination angle of the measuring instrument can be adjusted according to the surface of the object, the measuringprecision of the measuring instrument can be improved, and errors are reduced.
Description
technical field [0001] The invention relates to the technical field of measuring devices, in particular to an anti-shake high-precision grating projection type object surface topography measuring device. Background technique [0002] At present, there are certain macroscopic and microscopic geometric shape errors on the surface of machined parts and asphalt mixture, cement concrete and other compatible materials. And its spacing, surface roughness has an important impact on the performance of parts, urging the continuous improvement of mechanical manufacturing and testing automation, the detection of surface roughness has increasingly attracted people's attention. [0003] There is a very important relationship between the degree of friction on the surface of an object and the topography of the surface of the object. To study the degree of friction on the surface of an object, it is generally necessary to measure the surface topography of the object. When measuring the surf...
