Description
Technical Field
The invention belongs to the technical field of gravity center measuring equipment, and particularly relates to gravity center measuring equipment for a machined part.
Background
Parts of an object are subjected to the force of gravity. In effect, we can think that the gravity action received by each part is concentrated on one point, which is called the gravity center of the object. Wherein the position of the center of gravity of an object with uniformly distributed mass is only related to the shape of the object. Regular objects have a center of gravity in the geometric center, while irregular objects have a center of gravity in a position that depends on the distribution of mass in the object in addition to the shape of the object, and the center of gravity of the object is not necessarily in the object. The measurement of the gravity center of an object has important significance in engineering and daily production. For example: the crane needs to work normally, the gravity center position of the crane meets a certain condition, and the floating stability of the ship is related to the gravity center position; a high-speed rotating machine which causes severe vibration if the center of gravity is not on the axis; the center position of the positioning workpiece is provided with a balance point which is beneficial to finding the workpiece, thereby facilitating operations such as shaping, reforming and forming a connecting hole around the center of the workpiece.
The existing method for measuring the gravity center of an object mainly comprises the following steps:
1. a suspension method comprises the following steps: only for thin plates (not necessarily uniform). Firstly, finding a thin rope, finding a point on an object, hanging the point by using the rope, drawing a gravity line of the object after the object is static, finding another point for hanging the point in the same way, wherein the intersection point of two gravity lines is the gravity center of the object;
2. a support method: only for thin rods (not necessarily uniform). Supporting an object by using a fulcrum, wherein the position is changed continuously, and the more stable the position is, the closer the position is to the gravity center;
3. needle top method: the same applies only to thin plates. A thin pin is placed against the underside of the plate, and when the plate is balanced, the pin is positioned close to the center of gravity.
Although the method can measure the gravity center of the object in a certain sense, for some plate-shaped workpieces with irregular shapes and uneven mass distribution, the workpieces are troublesome in measuring the gravity center of the workpieces due to the lack of proper connection points for connecting ropes, and the efficiency is low.
