The second spoke includes a second rim end, a second plate end and a second center plate end. The first and second spokes have a same structure and are arranged in a mirror-symmetrical manner. Several projection-welding points are disposed on opposing surfaces of the first plate end and/or the second plate end, the projection-welding points are annularly arranged at an interval, the projection-welding points are arranged in a form of a concentric circle to form a least two annular arrangements, welded fixation of the first plate end and the second plate end is completed through the projection-welding points. A cavity groove for holding a bearing is formed inside after the first and second center plate ends are docked.

A system for mounting a door hinge to upper and lower mounting portions of front and rear pillars of a vehicle body being transferred along a vehicle transfer line. The system includes: a jig frame installed to reciprocate in a vehicle width direction through a driving unit on a base frame outside the vehicle transfer line; a rotation index installed on the jig frame and rotatable by a predetermined angle through a servomotor; a vertical rotation shaft formed as a polyhedron having a cavity and coaxially connected to a rotation center axis of the rotation index along an up and down vertical direction; and a pair of clamping units installed through a mounting plate to a base plate fixed to each side of the vertical rotation shaft, the pair of clamping units being disposed at upper and lower portions of the mounting plate and configured to clamp the door hinge.

An automated clip application system for fitting clips in an automotive assembly line includes a cassette receiving station for receiving at least one cassette preloaded with a plurality of clips. The clips in the cassette are arranged in the same orientation. A dispensing opening dispenses clips from the cassette one at a time, and a robotic member is programmed to pick up the clips, one at a time, after they have been dispensed from the dispensing opening and fasten each clip in position in an automotive assembly.

A vehicle body assembling system forms a pre-buck section and a main buck section set along a transfer path of a floor assembly. A main buck unit is set at opposite sides of the transfer path in the main buck section, controls an upper portion of a side assembly in a state that a lower portion of each side assembly is pre-assembled to the floor assembly the pre-buck section, and assembles the upper portion of the side assembly and vehicle body parts using a second welding robot.

A leaking oil dipstick adapter is repaired by removing a flanged nut from a threaded extension of the dipstick adapter. A gasket and preferably also gasket seal forming material are applied surrounding the threaded extension of the dipstick adapter and adjacent to an exterior side of the wall of the oil pan. A washer is applied adjacent to this gasket. A nut is threaded onto the threaded extension of the dipstick adapter and applies a compression force on the washer, compressing the gasket against the exterior surface of the wall of the oil pan. A tool is preferably used to retain the dipstick adapter and keep it from falling into an interior of the oil pan during the repair.

The disclosure relates to a system and method for changing location pins on a pallet for an assembly line. The system may include a plurality of pallets, each pallet including at least a first and second sockets configured to receive a location pin. The system may include a pin changing unit located between a top assembly line and a lower return line. The pin changing unit may include a pin grabber configured to engage the location pin within the first socket. The pin changing unit may include a horizontal linear actuator configured to move the pin grabber and the engaged location pin into alignment with the second socket. The pin changing unit may include a vertical linear actuator configured to extend the pin grabber into engagement with the location pin and retract the pin grabber away from the location pin.

A method for performing operations on a target workpiece including taking an operating tool unit by an industrial robot, carrying the tool unit to the workpiece, releasing the tool unit at the workpiece, moving the robot away from the tool unit, performing one or more operations on the workpiece through the tool unit while the tool unit moves with the workpiece; and retrieving the tool unit from the workpiece after the tool unit has performed the one or more operations on the workpiece. A robotic assembly for performing a method including at least one industrial robot, at least one operating tool unit, and a quick tool changer for detachably coupling the tool unit with the industrial robot including a first tool changer part arranged in the industrial robot and a second tool changer part arranged in the operating tool unit.

Systems, methods and apparatus for automated vehicle wheel removal and replacement are provided. One system includes a computer system with applications for scheduling the replacement of tires for the vehicle. An electronically controlled lift device and robotic apparatus is configured for interaction with the computer system. The lift device mechanically adjusts arms for placement on lift points of vehicles. The robotic apparatus detects positioning of lug nut configuration for a wheel, removes lug nuts, and then removes the wheel from the wheel hub with gripping arms. The wheel and tire are then handed off to a separate tire changing machine. When a new tire is replaced the robotic apparatus then mounts the wheel to the original wheel hub, and then secures the lug nuts to the lug nut bolts.

The present disclosure relates to an axle beam, in particular an axle bridge, for a motor vehicle, preferably a commercial vehicle. The axle beam has a first axle beam shell and a second axle beam shell which is connected, in particular welded, to the first axle beam shell in order to configure a tubular body. The tubular body has an inner circumferential face with a plurality of flat sections which form a non-round cross section of the tubular body. The axle beam has a reinforcing component which has a non-round cross section, is arranged within the tubular body, and bears at least partially against the flat sections of the inner circumferential face of the tubular body.

A device for removing burrs from a back cavity of a wheel includes a lower lifting synchronous movement arrangement, an outer ring brush arrangement, an inner ring brush arrangement, a synchronous movement arrangement and an upper lifting drive arrangement. When the device is used, an upper cylinder drives four clamping blocks to clamp the wheel synchronously through an upper guide rail, an upper gear and upper racks; an upper cylinder drives the wheel to rise and separate from a roller bed through upper guide pillars and upper guide sleeves; an upper servo motor drives the clamped wheel to rotate through an upper rotating ring. The present invention can be used for not only polishing the burrs at the back cavity of the wheel, but also accurately adjusting the position of each brush according to the flange size and the back cavity diameter of the wheel.
