Abstract
Annular knurl formula steering wheel gasbag fixed bolster belongs to the auto -parts field. Base member in the current steering wheel gasbag fixed bolster subassembly is when stamping operations, and external member easy base member of following in the axial drops, the utility model discloses a base member and external member, base member are equipped with the central through hole, are equipped with the shaft shoulder on the outer disc of base member, and the fixed suit of external member is on the base member of shaft shoulder one side to carry out axial positioning by the shaft shoulder on the base member, the external member center be equipped with with the corresponding ladder through -hole of central through hole is equipped with axially extending bore on the side end face of external member corresponding to the supporting pad, set up the annular knurl on the outer disc of base member of shaft shoulder one side. The utility model provides the ascending firm degree of external member axle has been strengthened to cohesion between high external member and the base member, and the external member can not come off from the base member because of the stamping press.
Description
Technical field
The utility model belongs to vehicular spare parts field, especially relevant with a kind of knurl type 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 knurl type bearing circle air bag fixed support that matrix comes off.
For this reason, the utility model is by the following technical solutions: knurl type 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 arranges annular knurl, external member is fixed on the matrix of shaft shoulder side as insert-molding injection moulding, pass through annular knurl, the friction force of matrix periphery can be increased, improve the binding force between external member and matrix, strengthen the firmness of external member on matrix, end, matrix one end is when carrying out flange operation, under stamping press, described external member axially can not come off from described matrix.
As to technique scheme supplement and perfect, the utility model also comprises following technical characteristic.
The described matrix periphery being provided with annular knurl is provided with annular groove, and described external member inwall is provided with the annular protrusion corresponding with described annular groove, and the annular protrusion on external member inwall embeds the annular groove on matrix, carries out axial limiting to external member.
The cross section of described annular groove is rectangle.
The utility model can reach following beneficial effect: 1, by arranging annular knurl on the matrix periphery of shaft shoulder side, adding the friction force of matrix periphery, improve the binding force between external member and matrix, strengthening external member stable degree axially; 2, by arranging annular groove on the matrix periphery being provided with annular knurl, the contact surface between external member and matrix can be increased, carrying out spacing to external member in the axial direction simultaneously, increase external member at base shaft firmness upwards.
