Abstract
The invention relates to an umbrella nut for automobile assembling, wherein a blind hole is designed in a nut body; the upper section and the lower section of the nut body are cylindrical, the middle section thereof is a transitional cone, the lower end face of the cone is a welding surface with a lower supporting plate, and the upper end of the nut body is provided with a guiding positioning step for guiding the welding of the nut body and the upper supporting plate. The joint position of the middle section transitional cone and the lower section of the nut body is also provided with a small-radian cone transitional section. Because the middle section of the nut body of the umbrella nut is designed with a cone transitional section which can transmit and break down force excellently, thus the occurrence of stress concentration at the transitional root of a welding molded surface of the nut is avoided. With the guiding positioning step designed on the upper end of the nut body, the clamping and the positioning of the supporting plates in welding are convenient. The small-radian cone transitional section arranged at the joint position of the middle section and the lower section of the nut body can further release the stress concentration at the transitional root of the welding molded surface of the nut.
Description
Technical field
The present invention relates to a kind of nut structure.
Background technique
In the vehicle structure design process, when carrying out the selecting for use of nut, bolt, be designated as the master with GB and enterprise basically, but at the assembling of part, common tender is to satisfy their requirements.The nut body that a kind of nut is arranged now is unified cylindrical body, need right angle step be set with the position of assembly parts welding, the nut of this structure in use can influence on the one hand the power transmission of part, structure and stressed, even influence the car load correlated performance, on the other hand, be subjected to the restriction and the requirement of each side such as current structure, position, performance, if from the structure consideration of getting on, brand-new design, coupling can be dropped into a large amount of time and moneys, may also can't well solve, many times need the nut of design specialized to solve the requirement of each side such as assembly performance.
Summary of the invention
The present invention proposes a kind of automobile assembling umbrella nut, improves its transmission and decompose the general assembly part to be delivered to power on this nut, simplifies the structure of mounting points simultaneously.
Technological scheme of the present invention is as follows:
A kind of automobile assembling umbrella nut has nut body, and design has blind hole in the nut body; Described nut body two sections are cylinder type, middle section transitional cone, and conical lower end surface is and the face of weld of lower supporting plate that the upper end of nut body is useful on the guide-localization step with upper backup pad welding guiding.Binding site at middle section transitional cone and hypomere also has cone transitional section.
The present invention is owing to designed conical changeover portion in the stage casing of nut body, and it can well transmit power and decompose, and avoids nut the stress concentration phenomenon to occur at the transition root of welding profile.By at upper end shaping-orientation positioning step, make things convenient for the location that is installed of dunnage when welding.By the transition circle conical surface of another little radian is set at stage casing and hypomere binding site, can further alleviates nut and the stress concentration phenomenon occur at the transition root of welding profile.This nut is used the fit on of automobile, can solve at the planeness and the intensity correlated performance of nut own that are subjected to car body structure restriction and Assembly part to each mounting points and require under the situation, transmission and decomposition to corresponding excitation force, simultaneously according to can suitably adjusting (as: mounting points before and after the fore sub frame) under the requirement of fitting plane degree to nut, avoid car body structure redesign, join a job, provide cost savings, a large amount of inputs of time.

Embodiment
Referring to Fig. 1, Fig. 2, the structure shape of the nut body of this nut is divided into three sections, epimere 1 and hypomere 5 all are straight cylindrical bodys, when design, to adjust length according to the relevant actual conditions of restrictions such as current structure, position, guide-localization step 1 when the upper end of epimere 2 is upper backup pad and the welding of this nut, the location that is installed of dunnage during convenient the welding.Stage casing 3 is the taper shape of transition, and conical lower end surface is the face of weld 6 with lower supporting plate.The binding site of 3 transitional cone and hypomere 5 also has the cone transitional section 4 of a little radian in the stage casing, and this two-part circular cone transition design can well be transmitted power and decompose, and avoids nut two profile transition roots the stress concentration phenomenon to occur.This nut design simultaneously is blind hole structure, has also guaranteed the structural strength of nut upper end.
According to structure shown in Figure 3; automobile is subjected to the restriction of lower supporting plate 9 structures at this place; be difficult to it is adjusted; reduce mounting plane; then selected this umbrella nut for use; after umbrella nut 8 and lower supporting plate adorned 9 cards; make that face of weld 6 contacts with lower supporting plate 9 under the nut, and weld with the mode of protection weldering, the guide-localization step 1 of upper end welds mutually with upper backup pad 7; form a complete structure; such mechanism can effectively decompose the excitation force of Assembly part transmission, alleviates the stress of lower supporting plate part, simultaneously; nut structure can effectively transmit the stress between two-part transition profile own, to promote the overall structure rigidity.
Claims (1)
