Abstract

The invention relates to a self-locking thread sleeve device which comprises a mounting body and a thread sleeve. A threaded hole for mounting the thread sleeve is formed in the mounting body; a locking part of which the diameter is greater than that of the threaded hole is arranged at the end part of the threaded hole; the locking part is coaxial with a screw thread; an external screw thread is formed on the thread sleeve; a screwing-in device is arranged on the thread sleeve; a spline is arranged at the end part of the outer diameter. According to the self-locking thread sleeve device disclosed by the invention, a sawtooth securing ring does not need to be separately mounted; the self-locking thread sleeve device is applicable to various occasions and particularly a situation that due to an excessively thin mounting wall, the sawtooth securing ring cannot be used.

Description

Self-locking thread insert device
Technical field
The present invention relates to a kind of self-locking thread insert device, it is possible to achieve in the structure that assembly wall is relatively thin, realize the auto-lock function of swivel nut.
Background technology
The installation of mechanical part or when coordinating, the reasons such as material for overcoming matrix is softer, often at mating surface, swivel nut need to be installed.Sometimes swivel nut is for realizing its function, it is necessary to have lock function, it is prevented that rotate.Traditional swivel nut locking is realized by sawtooth dead ring, and namely the firm ring of sawtooth is arranged on swivel nut installing hole by the mode of interference, and the sawtooth of its internal diameter blocks swivel nut and realizes the locking of swivel nut.And installing space is relatively big needed for this structure, when the installation sub-aperture position wall thickness that need to install swivel nut place is relatively thin, sawtooth dead ring just cannot be used to realize the locking of swivel nut.
Summary of the invention
It is an object of the invention to provide a kind of self-locking thread insert device, it is possible to achieve in the structure that assembly wall is relatively thin, realize the auto-lock function of swivel nut.
The technical scheme is that, described self-locking thread insert device includes fixing body, swivel nut, and described fixing body is provided with the screwed hole installing swivel nut, and the end of screwed hole is provided with the diameter tight lock part more than screwed hole diameter, described tight lock part and threaded coaxial；Being provided with external screw thread on swivel nut, swivel nut can be arranged on fixing body by external screw thread, and described swivel nut is provided with screwing device, and the end of external diameter is provided with spline.Described screwing device is at swivel nut female thread or near three places of end setting or groove uniform everywhere, the described end arranging groove is positioned at spline one end.Described spline is SHUR-LOK spline.
The present invention is in use, by instrument and utilize the screwing device on swivel nut to be arranged on the screwed hole of fixing body by swivel nut, when the spline on swivel nut is screwed into the tight lock part on fixing body, by stamping tool, swivel nut is carried out punching press, described stamping tool will be provided with the position outward radial spreading of spline on swivel nut, and fit with the tight lock part on fixing body, and spline is made to block tight lock part, it is achieved the self-locking of swivel nut.The present invention need not separately installed sawtooth dead ring, it is adaptable to various occasions, and especially assembly wall is crossed thin and cannot be used the situation of sawtooth dead ring.
Accompanying drawing explanation
Fig. 1 is the configuration diagram of the non-locking of the present invention；
Fig. 2 is the configuration diagram after the locking of the present invention.
Detailed description of the invention
As it can be seen, self-locking thread insert device includes fixing body 1, swivel nut 2, described fixing body 1 being provided with the screwed hole installing swivel nut 1, the end of screwed hole is provided with the diameter tight lock part 3 more than screwed hole diameter, described tight lock part 3 and threaded coaxial；Being provided with external screw thread on swivel nut 2, swivel nut 2 can be arranged on fixing body 1 by external screw thread, and described swivel nut 2 is provided with screwing device, and the end of external diameter is provided with spline 4.Described screwing device be on swivel nut 2 female thread or end arrange three places or groove uniform everywhere, the described end arranging groove is positioned at spline 4 one end.Described spline 4 is SHUR-LOK spline.
