The utility model relates to a gripping mechanism for a knife bearing of a centroid measuring device. The motor drives a screw rod to rotate, the screw rod drives a push frame, and the push frame drives a slider to slide on a guide rail. The inclined surface is in contact with the rolling bearing, and the clamping piece connects the rotating shaft and the tension spring. The holding parts are quarter circles, and there are four in total, which together form a circular structure. When the rolling bearing slides on the rolling slope, the holding member holds the knife bearing tightly. The guide rail is located on the platform of the gripping mechanism.
Description
Technical Field
The invention belongs to the field of centroid measurement, and particularly relates to a clasping mechanism for a knife bearing of a centroid measuring device.
Background
In the centroid measurement, the orthogonal knife bearing has the function of providing a supporting point for a measured product, the measured product can freely rotate around the supporting point, and in the centroid calculation, a very critical factor is the position uniqueness of the supporting point, because in the centroid measurement, the origin of a centroid measurement coordinate system of the whole measuring device is defined by the supporting point. During the measurement process, if the position of the point is changed, the accuracy of the centroid measurement is affected by direct product errors. Because the orthogonal knife bearing adopts the structure of double layers of knives and knife bearings, the knife bearing of each layer is not restricted along the direction of a knife line, and the knives are easy to shift along the direction of the knife line and the position of a bearing point is changed due to other uncertain factors in the installation or non-measurement state of a product before the measurement of the mass center, therefore, the two layers of knife bearings are very necessary to keep the same position state in each measurement state so as to ensure the measurement accuracy of the mass center.
Disclosure of Invention
The invention aims to: a clasping mechanism for a centroid measuring device knife holder is provided.
The technical scheme of the invention is as follows: a motor drives a screw rod to rotate, the screw rod drives a pushing frame, the pushing frame drives a sliding block to slide on a guide rail, a rolling inclined plane is arranged on the sliding block, a holding piece is in contact with a rolling bearing through the rolling inclined plane, and the holding piece is connected with a rotating shaft and a tension spring.
The clasping members are in a quarter circle shape, and are four in total to form a circular structure.
