AI Technical Summary

Problems solved by technology

Typically, torque application tools cannot move in more than a single direction in a fixture due to fixture constraints
Repurposed fixtures for installing fasteners of different housing designs with different bolt patterns are highly labor intensive and therefore expensive

Embodiment Construction

[0032] The following description is merely exemplary in nature and is not intended to limit the disclosure, application, or uses.

[0033] refer to figure 1 , the exemplary automotive transmission 10 includes a first housing portion 12 connected to a drive assembly portion 14 using a plurality of threaded fasteners 16 . Similarly, the second housing portion 18 may be attached at the opposite end of the drive assembly portion 14 using a plurality of fasteners 20 . The first and second housing portions 12, 18 and the drive assembly portion 14 are typically cast from a metal such as aluminum or steel. A gasket (not visible in this view) is disposed between the first housing portion 12 and the drive assembly portion 14 , and a gasket 22 is disposed between the drive assembly portion and the second housing portion 18 . In order to apply even load pressure across the pad, it is desirable to install each of the fasteners simultaneously and with a common torque.

Abstract

A reconfigurable fastener multi-spindle tool system includes multiple spindle assemblies, each including a support ring and a support arm sleeve received in the support ring and rotatable on a centrallongitudinal axis of the support ring. At least one support arm is connected to the support ring. The at least one support arm rotates with respect to the central longitudinal axis. A spindle is fixed to the support arm and is displaceable with respect to the central longitudinal axis. The spindle has an adaptor to temporarily retain and torque a fastener. A reaction plate is connected to the spindle and has a geometric shape. At least one template plate has multiple openings each having a geometric shape matching the geometric shape of the reaction plate. One of the openings receives the reaction plate thereby preventing axial rotation of the spindle.

Description

technical field [0001] The present disclosure relates to arbor tools for fastener installation and torque application in automotive driveline components, such as transmissions. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may or may not constitute prior art. [0003] Fasteners are commonly used to couple automotive driveline components, such as transmissions and differential cases. It is desirable to install all fasteners simultaneously and using a common torque such that the fasteners apply an even load across the surface area of ​​the gasket disposed between the shell portions. When multiple transmissions or differentials of the same design are assembled in a repeating sequence, the bolt pattern is the same for each component. Accordingly, multiple torque application tools can be incorporated into a common assembly or fixture so that all fasteners for a given housing design can be...
