When the positioning portion 200 is inserted into the through hole 21, the elastic member 210 is reset by the elastic force to limit the workpiece 20 between the second guide surface 212 and the supporting surface 110, that is, the mounting seat 100 and the positioning portion 200 can limit the workpiece 20 to move along the Z-axis direction.
When blanking, the workpiece 20 is moved in the positive Z-axis direction, the workpiece 20 first contacts the second guide surface 212, the workpiece 20 applies a force to the two elastic members 210 through the second guide surface 212, and the two elastic members 210 move toward each other under the force of the workpiece 20, so that the workpiece 20 can be separated from the positioning portion 200.
Thus, the loading and unloading operation can be realized only by applying force to the positioning part 200 through the workpiece 20, and the parts do not need to be mounted and dismounted, so that the loading and unloading time can be effectively saved, and the processing efficiency can be improved. In addition, the positioning fixture 10 positions the workpiece 20 through the through hole 21 in the workpiece 20, so that the positioning fixture 10 can be applied to the workpiece 20 with a large inclined surface on the side surface or an irregular outer contour shape, and the positioning device has wider applicability.
