Shaft sleeve positioning and installing mechanism for automobile door hinge

Abstract

The invention belongs to the technical field of automobile part assembly, and in particular relates to a shaft sleeve positioning and installing mechanism for an automobile door hinge. The shaft sleeve positioning and installing mechanism comprises a clamping part for clamping an auxiliary hinge, a positioning pliers part for supporting or clamping a shaft sleeve, a positioning part for positioning relative positions between the axis of the shaft sleeve and the axis of a pin shaft hole of the auxiliary hinge, and a pushing part for pushing the shaft sleeve and making the shaft sleeve move to the pin shaft hole of the auxiliary hinge along the positioning part, wherein the positioning pliers part does open and close movement relative to the shaft sleeve along an axis direction vertical to the shaft sleeve; the positioning part and the pushing part, and the clamping part are arranged on the two sides of the positioning pliers part; the positioning pliers part is away from the run paths of the positioning part and the pushing part when opened or closed; the external diameter of the positioning part is fitted with the internal diameter of the shaft sleeve; and the axes of the positioning part, the shaft sleeve and the pin shaft hole of the auxiliary hinge are overlapped. The mechanism has a simple structure, is convenient to maintain and can greatly improve the production efficiency and yield of the automobile door hinge.

Description

technical field [0001] The invention belongs to the technical field of assembly of automobile parts, and in particular relates to a shaft sleeve positioning and installation mechanism of an automobile door hinge. Background technique [0002] Automobile door hinges are a general term for components that are used to connect with the body and the door, and can rotate around the same axis in the up and down direction and are combined with each other. According to the hinge manufacturing process, it can be roughly divided into stamping hinges and profile hinges. Stamping hinges Hinges are widely used because of their simple form, good manufacturability and low cost. The stamping hinge is generally composed of a main hinge, a secondary hinge, and a shaft sleeve and a pivot pin used to connect the two. It usually includes processes such as ring threading, pin threading, screw riveting, and torsion measurement. The previous stamping hinge assembly methods are all Manually assembli...

Problems solved by technology

The stamping hinge is generally composed of a main hinge, a secondary hinge, and a shaft sleeve and a pivot pin used to connect the two. It usually includes processes such as ring threading, pin threading, screw riveting, and torsion measurement. The previous stamping hinge assembly methods are all Manually assembling the above parts, needless to say, the productivity is low, and the finished product rate is also low, especially in the ring threading process, there is no reliable mechanical ring threading mechanism at present, and at the same time, due to the gap between the shaft sleeve and the auxiliary hinge pin hole What constitutes an interference or transition fit, manual assembly is extremely time-consuming and laborious, and it also greatly affects the yield after assembly
