Abstract
The utility model discloses a nut fixing structure of an automobile frame, which comprises a frame body (1) and a nut (2). A nut box (3) is arranged on the frame body (1) corresponding to the nut (2) in position and provided with three flanges, three spaced outer sides of six sides of the nut (2) correspond to one another, the nut (2) is clamped along the rotation direction of a threaded axis of the nut (2), and the nut box (3) is fixedly connected on the frame body (1). By the aid of the technical scheme, thread looseness when the nut is screwed up is greatly reduced so that waste is greatly reduced; the mechanical behavior grade of a selected bolt is improved so that assembly operation is simple, and efficiency is improved; and the nut fixing structure is wide in application, and applicable to almost all bolt and nut assembly structures on an automobile.
Description
Technical field
The utility model belongs to the technical field of auto parts and components structure, relates to the structure of automotive body, and more particularly, the utility model relates to a kind of nut fixed structure of automobile frame.
Background technique
In the prior art, set screw nut is generally all taked the directly mode of assembling of projection welding or plain nut on automobile frame.
When adopting project-welding nut, its shortcoming is:
1, promptly the location is dead, stiff after the project-welding nut welding.When coaxality has a some deviation a little, when assembling bolt, the situation of slide nut tooth often appears.In case the whole vehicle frame of sliding tooth is basically just scrapped, the cost waste greatly.
2, the peeling strength grade of project-welding nut is restricted.Bolt (M12 * 1.25) the standard screw-down torque that the mechanical property that this product adopted of exploitation is 10.9 grades is 145N*m.Moment is merely 78.45N*m but the minimum of project-welding nut (M12 * 1.25) is peeled off permission.Adopt project-welding nut, when vehicle frame and control arm assembling, have very much and can project-welding nut be peeled off the vehicle frame body, can not satisfy matching requirements.
When adopting plain nut, its shortcoming is:
When 1, adopting plain nut to tighten, operator need entangle nut with back-up wrench on the other hand, hold air gun on the other hand and entangle bolt head and just can tighten, and operation is inconvenience extremely.Simultaneously unsighted, working efficiency descends, and operator's qualification is had relatively high expectations.
2, adopt plain nut, when assembling, need back-up wrench be put in vehicle frame inside and operate, at first need nut be fixed, do not allow its rotation, can it be tightened.When design, need reserve bigger space, influence the overall structure of vehicle frame.
The model utility content
The utility model provides a kind of nut fixed structure of automobile frame, its objective is make be threaded reliable and easy to operate.
To achieve these goals, the technological scheme taked of the utility model is:
The nut fixed structure of the automobile frame that the utility model provided; Described automobile frame comprises vehicle frame body, nut; The relevant position of nut is installed on described automobile frame, establishes nut box, described nut box is established three ribs; Corresponding with three outer side surfaces of being separated by in six outer side surfaces of described nut, at described nut along blocking described nut on the direction of axis of thread rotation; Described nut box is fixedly connected on described automobile frame.
Three ribs of described nut box are vertical bending with the position that described vehicle frame body contacts, and bending is protruding, form the welding limit, and described nut box is welded to connect through described welding limit and described vehicle frame body.
Between three ribs of described nut box and the outer side surface of described nut, be provided with the gap of 0.25mm.
The utility model adopts technique scheme, and the phenomenon of sliding tooth reduces wasting phenomena greatly when having reduced fastening nut greatly; Improved the mechanical property grade that bolt is selected for use; Assembly manipulation is simple, and efficient improves; Applied range is applicable to screw bolt and nut assembly structure nearly all on the automobile.
Description of drawings
The mark of facing down among expressed content of each width of cloth accompanying drawing of this specification and the figure is made brief description:
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the side schematic view of structure shown in Figure 1;
Fig. 3 is the A-A cross-sectional schematic among Fig. 2;
Fig. 4 is the nut mounting point schematic representation among Fig. 1 and Fig. 2.
Be labeled as among the figure:
1, vehicle frame body, 2, nut, 3, nut box, 4, the welding limit.
Embodiment
Contrast accompanying drawing below,, the embodiment of the utility model is done further detailed explanation, inventive concept, the technological scheme of the utility model are had more complete, accurate and deep understanding to help those skilled in the art through description to embodiment.
Like the structure of the expressed the utility model of Fig. 1 to Fig. 4, be a kind of nut fixed structure of automobile frame, described automobile frame comprises vehicle frame body 1, nut 2.The utility model is when the exploitation automobile front subframe, for control arm before better fixing assembles the technological scheme that proposes with nut.
In order to solve the problem that exists at the described present known technology of this specification background technique part and to overcome its defective, realize making the reliable and easy to operate goal of the invention that is threaded, the technological scheme that the utility model is taked is:
Extremely shown in Figure 4 like Fig. 1; The nut fixed structure of the automobile frame that the utility model provided; The relevant position of nut 2 is installed on described automobile frame 1, establishes nut box 3, described nut box 3 is established three ribs; Corresponding with three outer side surfaces of being separated by in six outer side surfaces of described nut 2, at described nut 2 along blocking described nut 2 on the direction of axis of thread rotation; Described nut box 3 is fixedly connected on described automobile frame 1.
The utility model is that promptly nut box 3 by a sheet metal part, in nut 2 is wrapped in, by the welding sheet metal part nut 2 is fixed on the vehicle frame body.
Three ribs of described nut box 3 are vertical bending with the position that described vehicle frame body 1 contacts, and bending is protruding, form welding limit 4, and described nut box 3 is welded to connect through described welding limit 4 and described vehicle frame body 1.
Compared with prior art, the utlity model has following advantage:
The phenomenon of sliding tooth when 1, having reduced fastening nut has greatly reduced a large amount of cost wastes.
2, applied range is applicable to screw bolt and nut assembly structure nearly all on the automobile.
3, improved the mechanical property grade that bolt is selected for use.
4, assembly manipulation is simple, and efficient improves.
Between three ribs of described nut box 3 and the outer side surface of described nut 2, be provided with the gap of 0.25mm.
The 0.25mm gap is left on three limits and three limits of sheet metal part of nut, makes nut can carry out the activity of trace in inside, has also limited the rotation of nut simultaneously.
Combine accompanying drawing that the utility model has been carried out exemplary description above; Obviously the concrete realization of the utility model does not receive the restriction of aforesaid way; As long as adopted the method design of the utility model and the improvement of the various unsubstantialities that technological scheme is carried out; Or the design of the utility model and technological scheme are directly applied to other occasion without improving, all within the protection domain of the utility model.
