Abstract:

A multi-axis electric spraying robot adapted for use in a hazardous environment includes a base having a first pressurized compartment and an arm assembly having a second pressurized compartment in which compartments electric motors are respectively located. The arm assembly is supported for movement on the base at one end thereof. The arm assembly includes a wrist adapted for connecting the opposite end of the arm assembly with a spraying tool. One electric motor is provided to drive each axis. The compartments are pressurized to prevent flammable gases or vapors from entering the first and second compartments during operation of the robot.

International Classification:

B21D 708

US Classification:

72168

Abstract:

A telescoping die for use in place of a conventional fixed die in a multi-axis tube bender. The telescoping die provides a means of automatically varying the distance to the moveable die thereby increasing the range of possible bend radii that can be formed while maintaining a close positioning between the feed mechanism and the telescoping die.

International Classification:

B23P 1702

US Classification:

225 94

Abstract:

A connecting rod fracture machine for fracture separating the caps and bodies of integrally formed connecting rod workpieces includes a cryogenic cooling station for embrittling the large ends, a fracture station for fracture separation of the embrittled cap and body portions, a warming station for returning fractured assemblies to ambient temperature and transfer mechanism for moving the workpieces between stations. The fracture station includes separable pilots for receiving the large end bores of the pieces to be fractured, an impact separation ram for rapidly separating the pilots to effect fracture separation and anti-rotation clamp means movable with the respective pilots and requiring linear separating motions of the caps from the connecting rod bodies.

Assignee:

General Motors Corporation - Detroit MI

International Classification:

B23C 300

US Classification:

409132

Abstract:

A method is disclosed for finishing a roughly shaped elliptical cylinder bore to an accurate final shape of predetermined major and minor axis. A circular cutter body with an effective diameter equal to the desired major axis. Then, a tilt angle is determined at which, when the circle of the cutter body is tipped away from the bore axis with the bore axis running through the center of the circle, a projection of the circle into a plane perpendicular to the bore axis will yield the desired minor axis. Then, the cutter body is powered about a secondary axis, at the tilt angle, relative to a bore primary axis and advanced linearly into the bore along the bore axis.

International Classification:

B23Q 710
B23P 1908

US Classification:

29809

Abstract:

A ring expander and assembly machine, having a loading station, a spreading station and assembly station, is operable to expand a spiral retaining ring in place on a workpiece. Spiral retaining rings with locking tabs and slots are transported on a shuttle from the loading station to the spreading station, at which location, scraper blades and fulcrum cams cooperate to spread the ring and remove the tabs from the slots so that an expansible collar assembly can be used to expand the ring. A transporter moves the collar assembly with the ring to the assembly station where a stripper sleeve removes the ring from the collar assembly to the workpiece.

Assignee:

General Motors Corporation - Detroit MI

International Classification:

B21B 3902
B21D 905

US Classification:

72133

Abstract:

A pusher bar assembly for a multi-axis tube bender acts to insert and withdraw the bending support mandrel, as well as to push the tube through the bender. A hollow sleeve with a diameter equal to the tube has sufficient length to contain both the mandrel and a piloting plug, which can be inserted between the free ends of both the tube and sleeve. A mandrel bar is slidably received through the sleeve, and so can extend the mandrel out of a stored position of the sleeve into the tube and back. A stop means stops the mandrel bar to locate the mandrel at the proper place in the tube. A push pull means on the mandrel bar also pushes the plug to a point where it bridges the free ends of the tube and sleeve with the mandrel stops. Therefore, a high pushing force can be directed from the sleeve to the tube without the free ends collapsing inside one another.

Assignee:

International Classification:

F16K 1704

US Classification:

137881

Abstract:

A valve assembly is provided for a paint color change system for directing paint to spray guns from either of two supply lines selectively while connecting the other line to exhaust, and simultaneously controlling the paint pressure as a function of pilot air pressure. A valve block contains two pairs of poppet valves, each pair having a common inlet chamber connected to one of the paint supply lines and containing a pair of poppets each biased toward a seat for controlling flow to an outlet chamber, and a pilot air operated diaphragm in each outlet chamber coupled with a poppet for regulating the position of the poppet in accordance with the paint pressure in the outlet chamber and pilot air pressure. The outlet chambers are connected to an exhaust line and the paint spray guns respectively so that the two pairs of poppet valves acting in concert under control of two pilot air signals can control which paint line is connected to the spray gun or to the exhaust as well as regulate the pressure or volume of paint flowing to the spray guns.
