Problems solved by technology

In the general installation method, the electric wrench socket is directly connected to the nut, which cannot guarantee that the bolt will not rotate
When the bolt rotates, the friction between the bolt and the split gasket will cause the split gasket to slip and rotate, which cannot make several gaskets evenly distributed, resulting in uneven force

Embodiment

[0033] like Figure 1~2 As shown, an electric installation tool for split nested unilateral bolt fasteners is used to install split nested unilateral bolt fasteners, such as Figure 5 As shown, the bolt fasteners include bolts 14, nuts 16 and split gaskets 15, the tool includes a main body and an input mechanism and an output mechanism arranged on the main body, and the output mechanism includes The sleeve 5 and the output shaft outer sleeve 7 sleeved outside it, the outer wall of the output shaft outer sleeve 7 is provided with the first gear 4 meshed with the input mechanism, and the output shaft outer sleeve 7 is connected with the nut 16 , the output shaft inner sleeve 5 is fixed on the main body, and the output shaft inner sleeve 5 is connected with the bolt 14. When the input mechanism rotates, the first gear 4 drives the output shaft outer sleeve 7 to rotate, so that the output The shaft inner sleeve 5 and the output shaft outer sleeve 7 produce relative rotation, so t...

Abstract

The invention relates to an electric mounting tool for a split nested one-sided bolt fastener, which is used for mounting the split nested one-sided bolt fastener. The bolt fastener comprises a bolt (14), a nut (16) and a split gasket (15); the tool comprises a main body, an input mechanism and an output mechanism; the input mechanism and the output mechanism are arranged on the main body; the output mechanism comprises an inner output shaft sleeve (5) and an outer output shaft sleeve (7) sleeving the inner output shaft sleeve (5); a first gear (4) which is connected with the input mechanism in a meshing way is arranged on the outer wall of the outer output shaft sleeve (7); the inner output shaft sleeve (5) is fixed on the main body; the outer output shaft sleeve (7) is connected with the nut (16); the inner output shaft sleeve (5) is connected with the bolt (14); and the input mechanism rotates and drives the outer output shaft sleeve (7) to rotate via the first gear (4), so that the bolt (14) and the nut (16) rotate relatively to finish mounting. Compared with the prior art, the electric mounting tool has the advantages of high reliability, high adaptability and simple structure.

Description

technical field [0001] The invention relates to a single-side bolt fastener installation tool, in particular to a split nested single-side bolt fastener electric installation tool. 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, staff need to work on both sides of the components at the same time, and there is still no good implementation method for unilateral installation. 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 components or components that are inconvenient to operate on the other side , it is impossible to use thi...
