The principle of the invention is illustrated as follows:
the designed gravity center adjusting mechanism is applied to a conveying transfer machine in the automobile manufacturing industry and is used for adjusting the gravity center balance when workpieces are hoisted, grabbed and conveyed; by using the gravity center adjusting mechanism, the gravity center can be continuously adjusted due to the change of parts, so that the balance and stability of the mechanism are ensured.
The workpieces to be picked are hung and taken, the gravity centers of the workpieces of different types are different, the gravity centers can move around along with the workpieces of different types, when the gravity centers move, the gravity center adjusting mechanism can adjust the gravity centers of the whole mechanisms through the sliding between the optical axis and the bushing and the balance of the spring force outside the bushing, and therefore stable conveying of the workpieces is guaranteed.
The limiting block is used for limiting the side edge of the third and fourth mounting seats, so that the optical axis and the graphite bush on the third and fourth mounting seats are prevented from moving, namely the gravity center adjusting mechanism is prevented from moving; and the coaxiality of the graphite bushing is adjusted to ensure that the optical axis moves smoothly.
The traditional transfer machine adopts a ball linear bearing mechanism, because the gravity center balance needs to be adjusted continuously, the ball linear bearing has large stress and is easy to crack, and once the ball linear bearing is cracked, the gravity center balance of the whole transfer machine fails. The graphite bushing is adopted to replace a ball linear bearing, so that the bearing capacity is increased, the stability of the mechanism is ensured, and the service life is prolonged. Meanwhile, in order to ensure the parallelism of the optical axis, the periphery is designed and installed with limit adjustment, thereby being convenient for adjusting the installation precision and being reliable in sliding.
