Detailed Description

The following description will explain embodiments of the present invention with reference to the accompanying drawings. As shown in fig. 1 to 5: a conveying device with an eccentric positioning mechanism comprises a rolling machine 1, wherein two eccentric positioning mechanisms which are symmetrically distributed by taking the axis of the rolling machine 1 as an axis are arranged on the rolling machine 1, a skid 2 is matched with the rolling machine 1, a signal switch 3 matched with the skid 2 is also arranged on the rolling machine,

The working process of the conveying device with the eccentric positioning mechanism provided by the embodiment of the utility model is as follows: under the action of the rolling machine 1, a skid 2 supporting a workpiece (a white body of an automobile) can drive the workpiece to move along the length direction of the rolling machine 1, when a signal switch 3 detects the skid 2, the skid is described to be in place at the moment, a control system can control air cylinders 6 in two eccentric positioning mechanisms to synchronously work simultaneously after receiving a signal of the signal switch 3, the air cylinders 6 can drive a front swing frame 7 to swing when working, the front swing frame 7 can drive eccentric wheels 12 to rotate when swinging, and the front swing frame 7 is connected with a rear swing frame 11 through a connecting rod 10, so that the front swing frame 7 and the rear swing frame 11 synchronously act, namely the front eccentric wheel 12 and the rear eccentric wheel 12 both rotate, the top plate 13 can be jacked upwards by the action of the eccentric wheels 12, the whole skid 2 is jacked upwards, and the skid 2 is separated from the rolling machine 1;

because the eccentric wheel 12 is propped against the V-shaped groove 14 formed in the bottom end face of the top plate 13, and the axial direction of the V-shaped groove 14 is perpendicular to the central axis of the rolling machine 1, when the eccentric wheel 12 props up the skid 2, the position of the skid 2 in the conveying direction (defined as the X-axis direction) of the rolling machine 1 can be automatically positioned under the action of the V-shaped groove 14, the eccentric wheel 12 can ensure the position accuracy of the skid 2 in the Z-axis direction, the position accuracy of the skid 2 in the Y-axis direction can be ensured by other mechanisms, and the position accuracy requirement after the skid 2 is lifted can be ensured by the structure;

after the relevant operation is finished, the control system controls the cylinder 6 to recover, the actions are performed in a reverse direction, the eccentric wheel 12 rotates to an initial state, the skid 2 descends and is in contact with the roller machine 1 again, and the roller machine conveys the skid 2 and the workpiece on the skid 2 to the next station.
