The utility model provides a base member among the current steering wheel gasbag fixed bolster when stamping operations, the external member is the easy problem that drops from the base member in the axial.
Description
Technical field
The utility model belongs to vehicular spare parts field, especially relevant with a kind of bearing circle air bag fixed support.
Background technology
Matrix and external member are support bracket fastened wherein two important spare parts of bearing circle air bag, matrix periphery is provided with a shaft shoulder, external member fixed cover is loaded on the matrix of shaft shoulder side, external member carries out axial location by the shaft shoulder on matrix, matrix and external member are respectively equipped with corresponding central through hole, when using installation, the end of matrix one end is needed to carry out enlarging flange, realize the installation of matrix, when carrying out stamping press, external member one end end face is pressed against on supporting pad as positioning datum end face, under stamping press, fracture phenomena is there is for preventing external member, usually axially extending bore is set at this external member end face, supporting pad is provided with the axial projection corresponding with described axially extending bore, the axial projection of supporting pad relies on described matrix through the axially extending bore of external member, the downforce that punching press produces is scatter, breaking of external member can be prevented, but in actual punching course, under stamping press, the easy in the axial direction periphery from matrix of external member comes off, affect installing and using of matrix.
Utility model content
The purpose of this utility model is intended to overcome matrix in existing bearing circle air bag fixed support when stamping press, the easy in the axial direction defect come off from matrix of external member, provides a kind of and can avoid external member when stressed from the bearing circle air bag fixed support that matrix comes off.
For this reason, the utility model is by the following technical solutions: bearing circle air bag fixed support, comprise matrix and external member, matrix is provided with central through hole, matrix periphery is provided with the shaft shoulder, external member fixed cover is loaded on the matrix of shaft shoulder side, and carry out axial location by the shaft shoulder on matrix, external member center is provided with the ladder hole corresponding with described central through hole, the side end face that external member corresponds to supporting pad is provided with axially extending bore, it is characterized in that, the matrix periphery of described shaft shoulder side is provided with the at right angles trapezoidal annular groove in cross section, the bottom width of described annular groove is less than the width of rebate of annular groove, the right angle waist of the corresponding described right-angled trapezium of a sidewall of described annular groove, form a right angle waist sidewall, described right angle waist sidewall is positioned on the described shaft shoulder shaft shoulder corresponding with described annular groove one side end face, described matrix inwall is provided with the corresponding annular protrusion of the annular groove at right angles trapezoidal with described cross section, external member is fixed on the matrix of shaft shoulder side as insert part forming injection moulding, the annular protrusion of described matrix inwall embeds the at right angles trapezoidal annular groove in described cross section, axial limiting is carried out to external member, simultaneously, increase the contact surface between described external member and described matrix, increase the volume of external member, make end, matrix one end when carrying out flange operation, under stamping press, described external member axially can not split away off from described matrix, strengthen the firmness of external member, installing and using of matrix can not be affected.
The utility model can reach following beneficial effect: by arranging the annular groove that a cross section is right-angled trapezium on matrix periphery, external member to be arranged and described cross section is the corresponding annular protrusion of the annular groove of right-angled trapezium, the annular protrusion of external member is flush-mounted in the annular groove of described matrix, can carry out spacing to external member in the axial direction, simultaneously, by increasing the contact surface between described external member and described matrix, increase the volume of described external member, make external member under punching press effect, axially can not split away off from matrix, installing and using of matrix can be ensured.
