CN-121989185-A - Rotary dial mounting bracket and method of making and using the same
Abstract
A mounting bracket for assembling a first component and a second component includes a bracket body rotatable relative to the two components and including a circular array of fastener through-holes, a threaded fastener passing through each fastener through-hole and into a threaded hole in the first component to thereby secure the mounting bracket to the first component. A locator pin protrudes from a central region of the bracket body, the locator pin being inserted into a pin aperture in the second component, thereby attaching the mounting bracket and the first component to the second component. A pair of fastener holes are positioned diametrically opposite each other across the locator pin and both are positioned a common radial distance from the locator pin. Another pair of fastener holes are located diametrically opposite each other across the locator pin, and each fastener hole is located a different distance from the locator pin.

Description
Rotary dial mounting bracket and method of making and using the same Technical Field The present disclosure relates generally to positioning features for aligning parts during part-to-part assembly. More particularly, aspects of the present disclosure relate to mounting brackets for aligning door panels during manufacture of a vehicle door assembly. Background Currently produced motor vehicles, such as modern automobiles, are initially equipped with compartment closure assemblies that are movably mounted to the vehicle body to cover various interior compartments of the vehicle and provide controlled access to those compartments. For example, in automotive applications, driver-side and passenger-side doors may be opened and closed to allow authorized users to enter and leave the passenger compartment. In contrast, a hood (referred to as an "bonnet" in some countries) extends over and covers the engine compartment of the vehicle to prevent theft or damage to engine components while allowing repair and maintenance. On the other hand, the trunk lid is hinged below the deck at the rear (or front) of the passenger compartment to cover the trunk compartment positioned at the rear (or front) of the vehicle. In contrast, pick-up trucks, sport Utility Vehicles (SUVs), van trucks and other cargo transportation vehicles are typically characterized by a rear cargo compartment that is closed at the aft end of the body by an articulating lift gate, tailgate or double gate assembly. For interconnecting the component parts forming the vehicle compartment closure assembly, the complementary parts may be positioned relative to each other by mating features that are too large or too small to provide part-to-part play. This defined spacing nature enables the production line operators to freely move the parts relative to each other to ensure proper alignment during the assembly process. The controlled part-to-part spacing may be provided by a bi-directional mounting bracket secured to one component and including male alignment features, such as protruding bosses. The male alignment features are received in corresponding female alignment features in the other component, such as through holes or recessed slots. Typically, there is a gap between each male alignment feature and its corresponding female alignment feature to accommodate expected dimensional and positional variations of the mating parts caused by manufacturing tolerances. Once aligned, the parts may be secured together by fasteners, clips, heat staking, or the like. Disclosure of Invention Provided herein are rotary dial mounting brackets for part-to-part alignment during assembly manufacturing, methods of making and using such mounting brackets, and motor vehicles having door assemblies constructed using such mounting brackets. By way of non-limiting example, rotary dial support is manufactured with a circular array of fastener through holes surrounding a center locator pin. The circumferentially spaced fastener holes mate in pairs, with the holes of each pair being positioned diametrically opposite each other across the center locator pin. The distance between each pair of mating fastener holes is the same as the fastener holes in the other mating hole pairs (e.g., the common hole-to-hole distance is about 44 millimeters (mm)). However, only one mating hole pair includes fastener holes equidistant from the center locator pin pair (e.g., each fastener hole in the first pair (0:0 origin) has a radial distance of about 22 mm). In contrast, the fastener holes of the other mating hole pairs each have a different distance to the center locator pin. For example, a second (-1: +1 offset) pair has one fastener hole with a radial distance to the center locator pin of about 21mm and another fastener hole with a radial distance to the center locator pin of about 23 mm. To simplify design and manufacture, the rotary dial support may be injection molded or die cast as a one-piece structure from a high strength polymeric material or a metal-containing material such as Acrylonitrile Butadiene Styrene (ABS) or 6061 aluminum alloy. The final stent body may be substantially planar and may have an asymmetric plan view profile. The stent body may have optional spur gear-like teeth spaced around and projecting radially outward from the circumference of the stent body. The center locator pin may be a frustoconical boss projecting perpendicularly from the central region of the bracket body. It may be desirable for the center of the circular array of fastener through holes to be eccentric (i.e., radially offset) from the axial center of the center locator pin. For ease of reference, fastener through holes may be labeled using intuitive classification schemes (e.g., 0:0, -1: +1, -2: +2, -3: +3; A1: A2, B1: B2, C1: C2, etc.). The fastener through holes may be circular, oval or square and share the same dimensions. Ribs may be added to the underside of the bracket body to structurally strengthe
