Embodiment Construction

[0023] In order to further explain the technical solution of the present invention, the present invention will be described in detail below in conjunction with the accompanying drawings.

[0024] see Figure 1 to Figure 12 As shown, this novel reaction arm includes KBK slide rail 29, suspension assembly and wrench box. KPK slide rail is connected with suspension assembly by pulley 51, and pulley 51 moves freely within the track length scope of KPK slide rail 29. The suspension assembly includes two side hanging plates 1, the hanging plates 1 on both sides are respectively connected with the KPK slide rail 29 through the pulley 51, and the first supporting shaft 28 and the second supporting shaft 24 are passed between the hanging plates 1 on both sides. connection, the limit ring 27 is passed through the two ends of the second support shaft 24, a linear bearing 25 is arranged on the second support shaft 24, a top plate 26 is connected to the upper surface of the linear bearing...

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...
