specific Embodiment

[0030] like figure 2 , The present invention is non-metallic insert slot nuts (hereinafter referred to as a nut) comprises a nut body and a non-metallic nut body fitted in an insert 2, 3 is provided with a threaded hole and a counter bore on the nut body 4, 3 and threaded holes 4 through a coaxial counterbore, in the axial direction of the nut body 1, a nut threaded hole is provided outside the main body side of the six flat circumferential surface, for mating with an impact wrench, nut counterbore-side outer peripheral surface of the present the tapered outer circumferential surface is, near the cell wall thickness and counterbore at the aperture position near the cell wall thickness is less than 4 at the bottom position of the hole.

[0031] In this embodiment, the stop nut groove 5 is provided at the counterbore end of the nut, and spaced circumferentially evenly arranged, in order to lock a stopper pin fitted on the bolt to achieve a nut with a mating bolt during assembly asse...

Abstract

The invention relates to a non-metallic insert slotted nut. The non-metallic insert slotted nut includes a nut body and a non-metallic insert embedded in the countersunk hole of the nut body. The opening corresponding to the end of the counterbore hole forms a flared structure. After the non-metallic insert is embedded in the nut body, the side wall of the counterbore hole on the nut body is folded inward to form a flanging, and the flanging is press-fitted on the non-metallic nut body. The inner conical surface of the insert increases the pressing contact area between the nut body and the non-metallic insert in the circumferential direction, and reduces the probability of the non-metallic insert turning or coming out during the nut installation process, and the flange can also be radially Restrict the inward deformation of the non-metallic insert, and reduce the probability of the non-metallic insert coming out of the nut body during the nut slotting process.

Description

Technical field [0001] BACKGROUND threaded fasteners present invention particularly relates to a non-metallic insert slot nuts. Background technique [0002] In the prior art non-metallic slotted insert nut, to form a metallic insert slot nuts, achieved by the nut and bolt fitted in the metallic insert nut and the nut defines a stop groove thread locking effect between the dual vice, which has a double lock structure of locking nut has good performance in important joints as civilian machinery, cars, etc., especially in the aerospace field with a wide range of applications. [0003] The above-described nonmetallic insert slot nuts, such as figure 1 Shown, comprises a nut body 101 and the metallic insert 102, nut body 101 is provided with a counter bore 104 coaxial with threaded bore 103 and a threaded hole 103 therethrough, the aperture size is larger than the threaded counterbore 104 of the large-diameter hole size 103 , non-metallic insert member 102 is axially open at both end...
