Abstract

The utility model belongs to a fastening tool in workpiece assembly, in particular to a fastening sleeve of an automobile oil pipe fixing piece. The structural key points are as follows: a counter bore capable of containing a copper gasket is processed on a fastening surface of the sleeve. The fastening sleeve has the advantages that the copper gasket is sunk into the sleeve; when the sleeve is used for locking a bolt, the copper gasket can not be deformed by torque force of the sleeve, all parts at joints are smooth and are well jointed, so as to enable oil is not easy to leak, so that the fastening sleeve can be widely applied on fixing various bolts using gaskets and further prevents the gaskets from being deformed.

Description

The fastening sleeve of automobile oil pipe fixture
Technical field
The utility model belongs to the fastened tools in the workpiece assembling, especially belongs to the fastening sleeve of automobile oil pipe fixture.
Background technology
Automobile oil pipe 4 is connected as shown in Figure 1 with wheel cylinder 8, respectively there is a copper backing 5 upper and lower end face of oil connection 7, lock with bolt 6 top, generally earlier add pneumatic adapter sleeve tube with pneumatic wrench and lock in advance in the locking process, add fastening sleeve with torque wrench then and lock at last, employed fastening sleeve is ordinary cartridge at present, end face is smooth, sleeve torsion acts directly on the copper backing, causes the copper backing stress deformation, and leakage of oil appears in assembling back joint easily.
Summary of the invention
The utility model purpose is to overcome the shortcoming that exists in the existing oil pipe connection, and a kind of copper backing that do not damage is provided, and joint, assembling back is not easy the fastening sleeve of the automobile oil pipe fixture of leakage of oil.
The technical scheme that the utility model adopted is a kind of fastening sleeve of automobile oil pipe fixture, and its structural feature is, can hold the counterbore of copper backing in fastening processing of sleeve.
The internal diameter of counterbore is greater than copper backing external diameter 5-10%, and the degree of depth is greater than copper backing thickness.
Advantage of the present utility model is that copper backing sinks to sleeve, when using the sleeve clamping screw, copper backing can not be subjected to sleeve torsion and produce distortion, and the joint smooth joint of each parts is good, is not easy leakage of oil, can be widely used on the bolting of various use pads, prevent the pad distortion.
