Abstract

The invention provides a device for tightening fasteners. The device for tightening the fasteners comprises a tightening assembly and a sleeve. The tightening assembly comprises a tightening shaft and a fixing piece, a limiting piece which is matched with the fixing piece is arranged on the outer wall of the sleeve, and the sleeve can be detachably mounted on a tightening shaft through mutual matching of the fixing piece and the limiting piece. The screwing assembly comprises a sleeve connecting tool which is fixed on the tightening shaft, the sleeve connecting tool comprises a driving mechanism which comprises a driving output piece, and the driving output piece is provided with the fixing piece. Under driving of the driving mechanism, the driving output piece can drive the fixing piece to be in butt joint with the limiting piece and to be disengaged from the limiting piece. The invention further provides the tightening assembly and the sleeve connecting tool in the device for tightening the fasteners.

Description

technical field [0001] The present invention relates to a tool for tightening fasteners in mechanical assembly, and components of the tool. Background technique [0002] The tightening of fasteners is an important process in the engine assembly process. For the fastening of important parts on the engine, multi-axis tightening machines are usually used to complete. The tightening shaft on the tightening machine should be connected with the sleeve, and different types of sleeves should be installed according to the size of the connecting part of the fastener. [0003] With the innovation of the engine, the structure of the fastener is also constantly updated, and the size of the connecting part will also change. A production line of an engine usually produces multiple models. When the model needs to be switched during the production process, the replacement of the tightening shaft sleeve must be involved. [0004] Current tightening machines such as figure 1 As shown, it in...
