Abstract

The invention relates to a single-side bolt fastener mounting tool with an adjustable ejector pin position. The single-side bolt fastener mounting tool is used for mounting a single-side bolt fastener, wherein the single-side bolt fastener comprises a round head bolt, a split type gasket, a sleeve, a gasket and a nut; the split type gasket, the sleeve, the gasket and the nut are sequentially arranged on the round head bolt in a sleeving mode in the axial direction; = the mounting tool comprises an operating rod and an ejector pin assembly; and the ejector pin assembly is arranged on the operating rod, can move along the axis of the operating rod and is fixed at a set position. Compared with the prior art, the single-side bolt fastener mounting tool has the advantages that the ejector pin position is convenient to adjust, stable and reliable.

Description

technical field [0001] The invention relates to the field of fastening and connection of structural parts in civil engineering and mechanical assembly, in particular to a single-side bolt fastener installation tool with adjustable thimble positions. Background technique [0002] At present, in the field of civil engineering and mechanical installation, there is a large demand for the installation of connection and fastening of structural parts. As far as bolts are commonly used at present, when performing connection and fastening operations on components, workers need to work on both sides of the component at the same time, that is, insert a bolt with a nut on one side, and then use a tool to tighten the nut on the other side . This connection and fastening method has simple structure, convenient operation and good load bearing, but it is only suitable for open cross-section components. In some special occasions, such as connecting and fastening closed cross-section compone...
