The present disclosure relates to a cage stud assembly and related methods of using a cage stud assembly.
This section provides background information related to the present disclosure and is not necessarily prior art.
Cage fastener assemblies can be used to couple, mount or otherwise connect various components. For example, a cage nut assembly can be used in an automobile or other vehicle to mount a component or subassembly to a body or other portion of the vehicle. The cage nut assembly can include a cage that houses a threaded nut. Methods of assembling first and second components with a cage nut assembly can include coupling or mounting the cage to the first component, and thereafter coupling a threaded bolt to the second component. The threaded bolt and the second component can then be coupled to the threaded nut and the first component by aligning and coupling the threaded bolt with the threaded nut. Aligning a bolt to a cage nut can be quite difficult. In some cases, the threaded nut is concealed by portions of the first component, by the second component through which the threaded bolt passes, or an intermediate component. Accordingly, it can be difficult to visually align and couple the threaded nut with the threaded bolt. In some cases, the weight of the second component must be supported by a person or machine while the threaded bolt is being aligned and coupled with the threaded nut, which also impedes alignment and threading.
It would be desirable to provide a new cage stud assembly and related method of use that facilitates easier alignment and threading of threaded fasteners, including a nut and cage stud assembly, in a variety of mounting applications.
This section provides a general summary of the disclosure, and is not a comprehensive disclosure of its full scope or all of its features.
In accordance with a first aspect of the present disclosure, a method of assembling a first automobile component relative to a second automobile component is provided. The method includes providing a cage fastener assembly that includes a cage and a first fastener. The cage includes a base portion and an arm portion defining a cavity. The first fastener includes a head portion at least partially disposed within the cavity and a threaded shank portion coupled to the head portion. The threaded shank portion extends from the cavity along a longitudinal axis. The method also includes fixedly coupling the cage to the first automobile component such that the longitudinal axis extends in a substantially horizontal direction during first and second automobile component assembly. The method further includes positioning the threaded shank portion through an aperture of the second automobile component such that a full weight of the second automobile component is supported by the shank. After supporting the second automobile component on the shank, the method also includes rotating a cooperating threaded fastener onto the threaded shank of the first fastener such that the first automobile component is fixedly coupled in a desired position relative to the second automobile component.
In accordance with another aspect of the present disclosure, a method of assembling a first automobile component relative to a second automobile component is provided. The method includes providing a cage fastener assembly that includes a cage and a first fastener. The cage includes a base portion and an arm portion defining a cavity. The first fastener includes a head portion at least partially disposed within the cavity and a threaded shank portion coupled to the head portion. The threaded shank portion extends from the cavity along a longitudinal axis. The method also includes fixedly coupling the cage to the first automobile component. The method further includes providing an intermediate automobile component over the cage fastener assembly such that the threaded shank portion visibly extends into the intermediate automobile component, while the cage is visibly obscured by the intermediate automobile component. The method also includes positioning the threaded shank portion through an aperture of the second automobile component such that the positioning is aided by visibly locating the threaded shank extending through the intermediate automobile component. The method further includes rotating a cooperating threaded fastener onto the threaded shank of the first fastener such that the first automobile component is fixedly coupled in a desired position relative to the second automobile component.
In accordance with yet another aspect of the present disclosure, a method of assembling a first vehicle component relative to a second vehicle component is provided. The method includes providing a cage fastener assembly, including a cage portion and a first fastener retained within the cage portion. The first fastener includes a threaded shank extending from the cage along a longitudinal axis. The cage portion includes wings extending laterally from the cage portion. The method also includes riveting the wings to the first component with a self-piercing rivet such that the longitudinal axis extends in a substantially horizontal direction. The method further includes coupling the second vehicle component to the first fastener such that a weight of the second vehicle component is applied to the first fastener in a direction transverse to the longitudinal axis. The method also includes coupling a second fastener to the first fastener such that first vehicle component is fixed relative to the second vehicle component.
In accordance with a further aspect of the present disclosure, a cage fastener assembly is provided. The cage fastener assembly can include a cage and stud. The cage can include a base portion and a pair of arm portions. The base portion and the pair of arm portions can define a cavity. The base portion can further define a first longitudinally extending width, and the arm portions can each define a second longitudinally extending width that is less than the first longitudinally extending width. The stud can include a head portion and a shank portion. The head portion can be at least partially disposed within the cavity of the cage. The shank portion can extend through the base portion of the cage.

With reference to
The cage fastener assembly 10 can include a cage 20, a stud fastener 22, and a second or cooperating nut fastener 24. As will be explained in more detail below, a portion of the stud fastener 22 is adjustably retained within the cage 20. Accordingly, the cage 20 can be coupled to any of the first, second and intermediate components 12, 14, 16, and the stud fastener 22 can be coupled to another of the first, second and intermediate components 12, 14, 16, such that the first, second and/or intermediate component(s) 12, 14, 16 is coupled to the other(s) of the first, second and/or intermediate components 12, 14, 16. In this regard, in some configurations, the stud fastener 22 comprises a threaded bolt, and the nut fastener 24 may include a threaded nut, such that the nut fastener 24 can threadably engage the stud fastener 22.
The cage 20 can include a base portion 26 and a pair of arm portions 28. The base portion 26 can be integrally formed with the arm portions 28, such that the cage 20 includes a monolithic or unitary construct. In this regard, it will be appreciated that the cage 20 may be manufactured by stamping, casting, machining, additive manufacturing, or other suitable process. In this regard, in some configurations the cage 20 may be formed from steel (e.g., high strength low alloy steel), aluminum, or another metallic material that is suitable for self-piercing rivet applications, as will be discussed in more detail below. With reference to
As illustrated in
A component-engaging surface 44 of the base portion 26 can extend from and between the first and second ends 34, 36 and the first and second transition portions 38, 40. As illustrated in
The arm portions 28 extend from the first and second transition portions 38, 40 of the cage 20, and include a proximal portion 48 and a distal portion 50. The proximal portion 48 can extend from the base portion 26, and the distal portion 50 can extend from the proximal portion 48. As illustrated, the proximal portions 48 can be generally parallel to one another and generally perpendicular to the base portion 26. The distal portions 50 can be generally parallel to one another and the base portion 26, and generally perpendicular to the proximal portions 48. In this regard, as illustrated in

The stud fastener 22 includes a head portion 60 and a threaded shank portion 62. In some configurations, the shank portion 62 can be integrally and monolithically formed with the head portion 60 by casting, machining, additive manufacturing, or other suitable manufacturing process. In other configurations the shank portion 62 can be mechanically fastened to the head portion 60 by threading, press-fitting, welding, or other suitable fastening technique. In this regard, in some configurations the stud fastener 22 may include an ASTM F568M Class 10.9 bolt that includes quenched and tempered steel (e.g., alloy steel, carbon steel, stainless steel, etc.), suitable for high load applications.

It will be appreciated that in some configurations the weight of the second component 14 and/or the stud fastener 22 can extend in a direction substantially perpendicular to the axis A. Accordingly, the assembler may disengage from, or otherwise let go of, the second component 14 in order to pick up or otherwise grab the nut fastener 24 and/or a tool(s) for engaging the nut fastener 24. The configuration of the cage fastener assembly 10, including the shank portion 62, can ensure that the aperture 42 of the first component 12 remains aligned with the aperture 80 of the second component 14, and that the shank portion 62 remains aligned with both of the apertures 42 and 80, when the assembler disengages either or both of the first and second components 12, 14 prior to engaging the nut fastener 24 with the stud fastener 22. As indicated above, in some configurations, the first component 12 can be a body or frame portion of the vehicle, while the second component 14 can be a door of the vehicle, or portion thereof, having an axis of rotation A1 (
While the weight of the second component 14 is supported by the shank portion 62, and while the assembler remains disengaged from either or both of the first and second components 12, 14, the shank portion 62 can be coupled to the nut fastener 24. In this regard, it will be appreciated that the configuration of the cage fastener assembly 10, including the shank portion 62 visibly extending through the first component 12, can make it easier for the assembler to not only align the shank portion 62 with the aperture 80, but also to couple the shank portion 62 to the nut fastener 24 without having to support the second component 14 (e.g., without having to support the weight of the second component). In some configurations the nut fastener 24 may include a threaded nut, such that the nut fastener 24 is rotated to threadably engage the threads 78 of the shank portion 62.
