A centroid measuring instrument

Abstract

The invention discloses a centroid measuring instrument, which comprises a flat plate, a horizontal plate and a bottom plate. A first ball groove is arranged in the middle of the upper end of the flat plate, and a rubber skin is bonded to the inner wall of the first ball groove. The inner wall is provided with a semicircular protrusion, and the upper end of the flat plate is fixedly installed with sliding columns on both sides, and the upper end of the sliding column is fixedly connected with the limiting plate, and the two sides of the horizontal plate are provided with sliding holes, and the horizontal plate passes through the sliding Hole slide socket for strut. The graphite inclined block presses against the inclined surface of the pressure column, the guard plate stably resists the left and right sides of the aerial camera, and the pin is inserted into the slot to stabilize the position of the aerial camera and facilitate the retention of the ellipsoidal aerial camera. The cooperation between the pressed graphite ball and the rotating shaft makes the shaft and the shaft ring well lubricated, which in turn makes the flat plate drive the rotating column to turn over more smoothly and stably, preventing the locking mechanism from falling when the center of mass of the aerial camera is offset.

Description

technical field [0001] The invention relates to the technical field of centroid detection, in particular to a centroid measuring instrument. Background technique [0002] The center of mass is the center of mass of an object. It is also the center of gravity when the gravity field is uniform. It is an important parameter that needs to be accurately measured in many engineering fields. It has very important practical significance. When the center of mass deviates from the set geometric center point It is called eccentricity. For example, the center of mass of the aerial camera on the drone is very important for the design of the gimbal of the positioning camera. The deviation of the centroid has a great influence on the stability of the gimbal, so there is an urgent need for a high-precision general An instrument for determining the position of the center of mass of an object.

Problems solved by technology

[0003] The existing centroid measuring instruments mostly use the bolt locking mechanism to retain the ellipsoid-shaped aerial camera, but when tightening, it is necessary to twist multiple bolts to fasten the aerial camera, which is cumbersome to install. Knife block, for the aerial camera that needs to be measured after it is just designed, if the center of mass is seriously shifted, it is easy to make the locking mechanism slide down and break
