Abstract

The invention relates to a self-alignment shaft head clamping mechanism. A standard oil cylinder is fixed on a left fixed block and is in threaded connection with a left bracket; the part of the left bracket, extending to two sides parallel to the standard oil cylinder, is positioned in a groove of the left fixed block and is in sliding contact with the left fixed block; an adjusting oil cylinder is fixed on a right fixed block and is in threaded connection with a right bracket; the part of the right bracket, extending to two sides parallel to the adjusting oil cylinder, is positioned in a groove of the right fixed block and is in sliding contact with the right fixed block; support plates are arranged between the left bracket and a longitudinally distributed universal coupling shaft head and between the right bracket and the other longitudinally distributed universal coupling shaft head and are in threaded connection with the left bracket and the right bracket respectively; the contact surfaces between the support plates and the universal coupling shaft heads are arc surfaces with the same diameter, and the contact surfaces a and b between the supporting plates and the corresponding brackets are arc-shaped along the axis direction of the universal coupling shaft heads. The self-alignment shaft head clamping mechanism has the characteristics of being convenient to operate, flexible in adjustment, and capable of saving roller replacement time and auxiliary rolling time.

Description

technical field [0001] The invention relates to a metallurgical plate and strip rolling equipment, in particular to a self-aligning shaft head clamping mechanism. Background technique [0002] In order to save the time of changing rolls and improve the productivity of the strip, the shaft head clamping device is widely used in the strip rolling mill. The shaft head clamping device is driven by the oil cylinder to slide the left and right brackets to slide in the fixed block, and the shaft head of the universal coupling is embraced by the supporting plate on the bracket. The bracket and the pallet are joined together by bolts. In order to ensure the close contact between the bracket and the shaft head, the contact part of the shaft head of the pallet is arc-shaped, and the diameter is the same as that of the shaft head. When changing rolls, the shaft head clamping device holds the shaft head of the universal coupling tightly, and the flat head of the work roll performs a pu...
