Stacking tool for silicon steel sheets with open slots

A stacking tool for silicon steel sheets with open slots comprises a positioning cushion cover, a dummy shaft is arranged on the positioning cushion cover, limiting blocks and keys are symmetrically arranged on the side faces of the dummy shaft, a pressing sleeve is arranged at the top of the dummy shaft, and a nut is arranged above the pressing sleeve. A groove is formed in the top of the limiting block, a steel sheet pressing plate is arranged in the groove, and a pressing plate is arranged above the steel sheet pressing plate. And the keys are positioned on the open slots of the outer diameters of the steel sheets, so that the gradient of the stacked slots and the consistency in batch production can be ensured to be good. A limiting device is additionally arranged in the pressing process of the steel sheet, so that the situation that the steel sheet is pressed to deform due to too large pressure in the pressing process, and the size is out of tolerance is avoided. 一种开口槽矽钢片的叠装工具，包括定位垫套，所述定位垫套上设置有假轴，所述假轴侧面对称
