A joining method is a method of joining a plate set composed by a plurality of stacked plate members including a first plate member and a second plate member by using a tapping screw. When the tapping screw is advanced into the plate set while the tapping screw is rotated in a state of applying a pressure onto the plate set so as to form through-holes in the first plate member and the second plate member, a first pressure applied onto the tapping screw is reduced down to a second pressure at the time when the tapping screw penetrates the first plate member.

An apparatus for use in installing and verifying installation of a seal member in a component, and including a housing defining an interior sized to receive the component therein, and a moveable lid selectively positionable between a loading position and a sensing position. The apparatus also includes at least one seal sensor coupled to the moveable lid and configured to selectively align with a first sensing point on the component when the moveable lid is in the sensing position. The at least one seal sensor is configured to only actuate when pressed against the seal member positioned at the first sensing point.

A fastener insertion system, for use with an assembly stack-up, includes a fastener and an end effector. The end effector includes a drill bit for drilling a hole through the stack-up, a probe for determining a stack-up parameter, and a fastener feed head for installing the fastener into the hole and applying rotational torque to complete fastener installation. The fastener insertion system also includes a processing device and an angle sensor communicatively coupled to the processing device and to the end effector. The processing device is programmed to measure, with the rotation angle sensor, the angular displacement required to complete fastener installation and to transmit a signal representative of the measured angular displacement from the angle sensor to the processing device. The processing device is also programmed to compare the measurement of angular displacement required to complete fastener installation to a range of angular displacement indicative of correct fastener installation.

An agricultural implement for applying an ingredient to a geographic area, the agricultural implement includes a chassis, weight bearing conveyance devices, a component and a weight distribution system. The weight bearing conveyance devices including a fore conveyance device and an aft conveyance device. The fore and aft conveyance devices are connected to and carry the chassis respectively in a fore and an aft position. The component is carried by and coupled to the chassis. The weight distribution system is configured to allow an adjustment of a position of the component relative to the chassis.

The present invention relates to a method of adapting and manufacturing a separator system comprising multiple inclined separators for separation of respective substances or substances mixed in fluids from oil wells and adapting the separator system to a change in the substance or use with another oil well. The method involves determining percentage fraction of respective fluid phases in an oil from a specific oil well and at a specific time and estimating expected production rate from the specific oil well at a specific time to estimate the streaming capacity of each respective fluid phase through separators of the separator system. The method also involves arranging a plurality of interconnecting frameworks of pipes in parallel or serial depending on the estimate streaming capacity.

An adaptive mechanical joint control and stabilization process and device having particular usefulness in mechanical joints employing U-bolts. The method and device monitors at least two predetermined metrics during a fastener tightening clampload cycle and compares the work expended in achieving a target limit value. Through examining the work expended through the monitored metrics, additional clampload cycles will automatically be run until the monitored work expended for all of the fasteners falls within predetermined values increasing the stabilization of the joint and further advantages of increased residual clampload. The process and device is useful in separating clampload cycles which form or yield the fastener from a final clampload cycle which properly elongates the fastener for a secure clampload and stabilized joint.

A method for configuring a hand-held riveting tool operated by an electric drive to set a blind rivet element in a setting operation. The hand-held riveting tool includes a mandrel configured to perform an axial movement so as to perform the setting operation of the blind rivet element, and a control unit which monitors the axial movement of the mandrel. The mandrel includes a front end position to which the blind rivet element is fitted in a form-locked manner and/or a force-locked manner. The method includes axially moving the mandrel from the front end position into a rear end position which is assumed at a beginning of the setting operation, and automatically adjusting the rear end position of the mandrel based on a parameter provided to the control unit.

Embodiments relate to a recliner automatic fastening system and a recliner automatic fastening method, which allow a cushion of a car seat and a nut of a back frame to be automatically fastened. The system includes an articulated robot installed along a conveyor line of a car seat, a vision check part checking a position of a nut temporarily fastened to the car seat using 2D vision sensing and then notifying the position to the articulated robot, and performing vision sensing on the nut that has been fastened, a nut fastening part installed on the articulated robot and fastening the nut when it moves to the position of the nut that is temporarily fastened by the articulated robot, and a fastening check part checking whether the nut is normally fastened using sensing data obtained by performing vision sensing on the fastened nut received from the vision check part.

A system for preloading a fastener of a mechanical fitting includes a strain measuring device to measure a strain on the fastener as the fastener is tightened. The mechanical fitting may include a base structure and a plate member. A support structure supports the plate member at a predetermined spacing from the base structure. The support structure may include a first sloping plate and a second sloping plate each extending between the plate member and the base structure. The fastener extends through a first hole in the plate member and a second hole in the base structure. The fastener is accessible through an opening on each side of the support structure. At least a portion of the strain measuring device is positioned relative to the fastener through a first opening of the openings to measure the strain on the fastener correlating to the preload as the fastener is tightened.

Two or more vehicle components can be operatively connected with one or more fasteners configured to provide selectively variable dampening characteristics. The fastener can include a dampening unit configured to provide different dampening characteristics based on a torque applied to the fastener. In one or more arrangements, the dampening unit can provide different dampening characteristics based on an amount of compression the dampening unit is under. Target dampening characteristics between two or more components can be determined. A torque can be determined and applied to the fastener based on the target dampening characteristics. The torque can cause the dampening unit of the fastener to compress and provide the target dampening characteristics between the components.
