Description
Technical field
The utility model belongs to fastening parts technical field, relates in particular to a kind of spline bolt of flanged dish.
Background technique
Bolt is a kind of fastening piece of extensive use, but the place in some specific (special) requirements, as for high strength, antifatigue, high temperature resistance and erosion-resisting occasion, be subject to the impact of bolt material, common material bolt does not in use reach Environmental Conditions requirement, produce the even fracture of losing efficacy, cause major accident.In prior art, existing various new materials, for the manufacture of bolt, as used GH4169 material, titanium alloy material, new type compound material etc., but cannot reach the effect that prevents from losing efficacy, reducing potential safety hazard preferably.In addition, the spline bolt of current flanged dish, the ability of bearing load and poor reliability, install very inconveniently, and installation efficiency is low.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned shortcoming and the spline bolt of the strong flanged dish of a kind of simple in structure, the convenient assembling and disassembling, high temperature resistance and the anti-fatigue ability that provide.
The utility model object and solve its technical problem underlying and realize by the following technical solutions:
The spline bolt of flanged dish of the present utility model, comprises spline body, cone, flange plate, interlayer, and interlayer afterbody is provided with screw thread.It is characterized in that: described spline body is fixedly connected with flange plate, and the joint of spline body and flange plate is provided with cone, and flange plate is connected with interlayer.
The spline bolt of above-mentioned flanged dish, wherein: described spline body is provided with 12 splines.
The spline bolt of above-mentioned flanged dish, wherein: evenly arrange in the rich center of described spline.
The spline bolt of above-mentioned flanged dish, wherein: described flange plate is circular.
The spline bolt of above-mentioned flanged dish, wherein: the material of described spline bolt is GH159 refractory alloy.
The utility model compared with the existing technology has obvious advantage and beneficial effect.From above technological scheme, described spline body is provided with 12 splines, is conducive to being screwed into fast and screwing out of the body of bolt, has greatly improved installation efficiency; Spline body is fixedly connected with flange plate, and the joint of spline body and flange plate is provided with cone transitional surface, contributes to increase the area of contact of bolt and fastened part, thereby increases the ability of its bearing load; The material of spline bolt adopts GH159 alloy, has improved high-temperature resistance.Visible, the utlity model has simple in structure, high temperature resistance, anti-fatigue ability is strong, and feature easy to install.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the left view of Fig. 1.
In figure, identify:
1, spline body; 2, cone; 3, flange plate; 4, interlayer; 5, screw thread.
Embodiment
Below in conjunction with accompanying drawing and preferred embodiment, spline bolt embodiment, structure, feature and effect thereof to the flanged dish according to the utility model proposes, be described in detail as follows.
Referring to Fig. 1 to Fig. 2, the spline bolt of flanged dish of the present utility model, comprises spline body 1, cone 2, flange plate 3, interlayer 4, and interlayer 4 afterbodys are provided with screw thread 5.It is characterized in that: described spline body 1 is fixedly connected with flange plate 3, spline body 1 is provided with cone 2 with the joint of flange plate 3, and flange plate 3 is connected with interlayer 4.Described spline body 1 is provided with 12 splines.Evenly arrange in the rich center of described spline.Described flange plate 3 is circular.The material of described spline bolt is GH159 refractory alloy.
During use, first by pneumatic impact wrench, the spline of spline body 1 is blocked, then according to certain orientation rotation, spline bolt can be screwed into fast under the effect of screw thread 5; On the contrary, if will screw out, only need to change sense of rotation.The utility model can be applicable to the occasion that aviation, navigation etc. have specific use.
The above, it is only preferred embodiment of the present utility model, not the utility model is done to any pro forma restriction, any technical solutions of the utility model content that do not depart from, any simple modification, equivalent variations and the modification above embodiment done according to technical spirit of the present utility model, all still belong in the scope of technical solutions of the utility model.
