Abstract
The invention discloses a rod piece structure for adjusting the precision of a multi-connecting-rod pressure machine and the multi-connecting-rod pressure machine. The rod piece structure is machined into a tapered shape by a matched surface between a rod body and a shaft sleeve and a pressing cover and a fixing piece (such as a bolt and a screw) are used for providing large and controllable axial force; and finally, the axial force is converted into friction force of the matched surface to prevent the shaft sleeve from rotation. The shaft sleeve is arranged in an eccentric structure and is rotated at a certain angle to realize the adjustment of the distances among rod holes. After the shaft sleeve is pressed in for the first time, a hole distance is measured. If the requirements are not met, a needed rotation angle is calculated. The shaft sleeve is knocked out from a rear end and then is pressed again by rotating the angle. The pressing cover and the bolt are arranged and the axial force is loaded by using the pressing cover and the bolt. According to the rod piece structure disclosed by the invention, unequal allowances of a same rod piece at different points of the pressure machine are reduced, the precision is improved, the detachment is convenient, the hole distance is adjustable, and the aim of improving the economical efficiency is realized. The invention further provides the multi-connecting-rod pressure machine provided with the rod piece structure.
