Abstract
A bolt retaining device for a nutrunner which includes a socket having a longitudinal axis and being sized to fit the bolt, the device having an electromagnet positioned with respect to the socket to generate a magnetic field directed along the axis of the socket to hold the bolt in the socket when the field is present, and a controller connected to the electromagnet controlling the magnetic field. The bolt retaining device wherein the electromagnet is a coil co-axially mounted with respect to the socket. Each nutrunner can include a motor, a socket, and a shaft connecting the motor to the socket. One or more nutrunners can be provided on a movable frame.

A bolt retaining device for a nutrunner which includes a socket having a longitudinal axis and being sized to fit the bolt, said device comprising an electromagnet positioned with respect to the socket to generate a magnetic field directed along the axis of the socket to hold the bolt in the socket when the field is present, and a controller connected to said electromagnet controlling the magnetic field.
A nutrunner for a bolt or nut comprising:
- a motor;
- a socket having a longitudinal axis and being sized to fit the bolt or nut connected to be rotated by said motor;
- and
- a bolt retaining device for the bolt or nut comprising an electromagnet positioned with respect to the socket to generate a magnetic field directed along the axis of the socket to hold the bolt in the socket when the field is present, and a controller connected to said electromagnet controlling the magnetic field.
A disassembly device for removing bolts or nuts from a workpiece on an assembly line, comprising
- a base positioned adjacent the assembly line,
- plural nutrunners mounted on said base, each nutrunner comprising a motor, a socket having a longitudinal axis and being sized to fit the bolt or nut connected to be rotated by said motor, an extensible shaft interconnecting said motor and said socket, and a bolt retaining device for the bolt or nut comprising an electromagnet positioned with respect to the socket to generate a magnetic field directed along the axis of the socket to hold the bolt in the socket when the field is present, and a controller connected to said electromagnet controlling the magnetic field;
- a frame mounted on said base and rotatably carrying said sockets of said plural nutrunners, said frame being movable toward and away from the workpiece,
- means for moving said frame toward and away from the workpiece,
- a mounting bracket on said frame, and
- a plurality of collar mounting flanges on said bracket, each said electromagnet being mounted on one said collar mounting flange, each said controller being mounted on said frame, said electromagnets and said controllers being carried by said frame during the movement toward and away from the workpiece.
