Novel connecting device for connecting rod and ball screw rod

Abstract

A novel connecting device for a connecting rod and a ball screw rod is fixedly arranged at the lower port part of the connecting rod by using bolts through a positioning flange; a ball head screw rod is arranged in a thread hole of the connecting rod through a middle hole of the positioning flange; a ball head polished cylinder is arranged at a part, which is close to a ball head, of the ball head screw rod; and the size of the ball head polished cylinder is identical with the free size of the center of the positioning flange. The positioning flange can mandatorily enable the axis of the ball head screw rod to be concentric with the axis of the positioning flange, so that the defect that parts among threads deform and are damaged due to the fact that local parts of the threads are excessively stressed because unbalanced loading exists in the stress between the connecting rod and the ball head screw rod and the defect that the threads between the connecting rod and the ball head screw rod are not easy to adjust or damage accidents of the equipment occur due to that the parts among threads deform and are damaged are avoided.

Description

technical field [0001] The invention relates to a connection device between a connecting rod and a ball screw, in particular to a novel connection device between a connecting rod and a ball screw, and belongs to the technical field of forging machinery. Background technique [0002] The connecting rod and the ball screw are important functional parts of the press. They transmit pressure by the cooperation of the internal and external threads of the two, and at the same time, the adjustment of the working mechanism of the press is realized by the adjustability between the two threads. At present, in the actual use process, it often happens that the thread between the two is difficult to adjust, and even the thread is damaged. The main reason for this phenomenon is that the connection mechanism between the connecting rod and the ball screw is through two The thread of the other is directly connected, this connection method is not reasonable, because the pressure transmission b...

Problems solved by technology

[0003] The purpose of the present invention is to provide a novel connection device for connecting rods and ball screw rods, which overcomes the problem of the existing press connecting rods and ball screw rods due to the use of direct threaded connections: The pressure transmission of the screw rod during work is not always carried out along the axes of the two, which may easily lead to unbalanced loading of the force between the threads, excessive local force, and deformation or even damage between the threads; and thus As a result, the thread between the connecting rod and the ball screw is not easy to adjust, or the equipment is damaged.
