Electromagnetic clamping method

摘要

A method for assembling parts. A sealant is placed between a plurality of parts in a stack up to form a workpiece. The workpiece is clamped using a permanent magnet unit and an electromagnetic clamping device in an activated state such that a number of forces caused by a magnetic field clamps the workpiece between the electromagnetic clamping device and the permanent magnet unit. A number of holes are drilled in the workpiece. A number of fasteners are installed in the number of holes.

1. A method for assembling parts, the method
comprising: placing a sealant between a plurality of parts in a stack up to form a workpiece; clamping the workpiece using a permanent magnet unit and an electromagnetic clamping device in an activated state such that a number of forces cause by a magnetic field clamps the workpiece between the electromagnetic clamping unit and the permanent magnet unit, wherein the permanent magnet unit is attached to a housing via a spring configured to bias the permanent magnet unit towards the housing, the permanent magnet unit further including a number of wheels, including a first wheel and a second wheel, a first lever having a first end and a second end, the first level connecting to the housing at a first pivot point and also connecting to the permanent magnet unit at about the first end, the second end of the first lever connecting to the first wheel; a second lever having a third end and a fourth end, the second lever connecting to the housing at a second pivot point and also connecting to the permanent magnet unit at about the third end and further connecting to the permanent magnet unit opposite the first lever, the fourth end of the second lever connecting to the second wheel; and an end effector attaching to the housing between the first wheel and the second wheel, and wherein the electromagnetic clamping device has both the activated state and a deactivated state; drilling a number of holes in the workpiece using the end effector; and installing a number of fasteners in the number of holes.
