A New Reaction Arm

Abstract

The invention discloses a novel reaction arm. The novel reaction arm comprises KBK slide rails, a suspension assembly and a wrench box. The suspension assembly comprises two lateral hang plates which are connected with the KPK slide rails through pulleys respectively, and the two lateral hang plates are connected through a first supporting shaft and a second supporting shaft. A linear bearing is arranged on the second supporting shaft, an ejection plate is connected to the upper surface of the linear bearing, the lower surface of the ejection plate is connected with the upper end of a supporting column, the lower end of the supporting column is connected with a lifting cylinder fixing plate, an air cylinder is fixedly connected to the lifting cylinder fixing plate, an extension end of the air cylinder penetrates the lifting cylinder fixing plate to extend downwards to act on a clamping mechanism through a connector, and the clamping mechanism is connected with a wrench box assembly. The novel reaction arm has advantages that a reacting force can be counteracted, an operator can be assisted in bolt alignment conveniently and effectively protected from being injured by the reacting force, and bolt screwing accuracy is guaranteed.

Description

technical field [0001] The invention relates to technological equipment for tightening bolts with relatively large moments, and more specifically relates to a novel reaction arm. Background technique [0002] With the upgrading of engine technology, the process has higher and higher requirements for engine tightening precision. At present, electric tightening guns are basically used for bolt tightening, but during the bolt tightening process with a large torque, the reaction force generated will be transmitted to the hands of the operator along with the tightening tool. Over a period of time, this reaction force can cause operator hand, wrist and shoulder fatigue, thereby affecting production. And when the reaction force is large, it will cause vibration during the tightening process, thereby affecting the tightening accuracy. Contents of the invention [0003] The purpose of the present invention is to provide a new type of reaction force arm, which can counteract the r...
