However, the split gasket in this split nested unilateral bolt fastener needs to be guided by the support rod, which is very inconvenient for installation.
The Chinese patent application publication number CN104690684A discloses an installation tool used in conjunction with the above-mentioned split nested unilateral bolt fastener. Although quick installation of the split nested unilateral bolt fastener has been realized, the There are still some defects in this tool, such as the installation accuracy is not high

Embodiment 1
[0030] A hydraulically driven unilateral bolt fastener installation tool, such as Figure 1-6 , used to connect and fasten the inner member 6 and the outer member 7 of the hole fixing plate. The fastener installation tool consists of an O-ring 1, an insert 2, a split gasket 3, a round head bolt 4, a screw 5, Composed of gasket 8 and nut 9, round head bolt 4 includes bolt head 4a and bolt shaft 4b, split gasket 3 is connected with round head bolt 4 through insert 2, the oil processed by insert 2 on round head bolt The radial displacement is limited by the road and the O-ring 1.
[0031] There are four split gaskets 3, and a small hole with the same diameter as the cutting strip 2 is processed on the inner wall of each split gasket 3, and the cutting strip 2 and the split gasket 3 can be interfered by external force Mates to make it a component. One side of the split gasket 3 is processed with a step, and the step can cooperate with the inner wall of the mounting hole, and the...

The invention relates to a hydraulic transmission type unilateral bolt fastener installation tool. The hydraulic transmission type unilateral bolt fastener installation tool comprises a sealing ring, split type gaskets, a round-head bolt, a gasket and a nut; the round-head bolt is provided with communicated oil ways in the axial direction of a bolt rod and the radial direction close to a bolt head; an open hole of the portion, in the tail portion of the bolt rod, of the corresponding oil way is provided with a threaded hole and provided with a corresponding screw; oil holes of the radial oil way are provided with corresponding inserting bars; the sealing ring is arranged on the inserting bars in a sleeving manner; and the split type gaskets are connected to the round-head bolt through the inserting bars. According to the installation tool, hydraulic oil in a bolt is used for controlling the split type gaskets to be shrunken and unfolded, the split type gaskets can pass through narrow and small connection piece installing holes and are unfolded on the other sides of connection pieces to reach installation positions, and the installation work of fastening of the unilateral bolt is achieved. The fastener installation tool has the beneficial effects of being accurate in installation, easy and fast to operate, small in size, small in weight, convenient to carry and the like and can conveniently perform batch operation in a building and industrial site.
Description
technical field [0001] The invention relates to a bolt fastener installation tool, in particular to a hydraulic transmission type single side bolt fastener 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, 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 components or components that are inconvenient to operate on the other side , it ...
