摘要:
A production system for manufacturing a workpiece comprises an index system including a plurality of index devices removably mounted on the workpiece at known longitudinally spaced locations therealong, and a longitudinally extending index member releasably engaged with at least two of the index devices such that a position and orientation of the index member are fixed relative to the workpiece by the index devices, the index member having position-indicating features distributed therealong. The production system further comprises a machine module mounted for longitudinal movement along the index member and operable to perform an operation, the machine module being operable to detect the position-indicating features on the index member and thereby determine a position of the machine module relative to the workpiece.

A cutting tool adjustment system comprising a body in the form of a cartridge (10) adjustably carrying a cutting tool (10a), adjustment means (17; 23; 29; 39) mechanically adjustably engageabe with the body for positionally adjusting a cutting edge of the cutting tool (10a), and means (19, 20; 30, 31; 34, 35) electronically engageable with the body aid including power supply means for powering display means (21; 28; 36) for indicating the adjustment of the cutting edge position.
摘要:
An optical unit for projecting an image including first and second locating lines for substantially eliminating the introduction of visual parallax error. In one preferred form, the optical unit is incorporated into a machine for performing a forming operation on a workpiece and is operative to project an image of a portion of a scale to a position easily read by the user during machine operation. The optical unit includes a prism portion having a first side disposed adjacent the scale, a second side at an angle to the first side for reflecting the image and a third side through which the projected image may be viewed. The first locating line is disposed on the first side and the second locating line is disposed on the third side such that visual alignment eliminates the introduction of visual parallax error associated with reading a scale.
摘要:
A portable cambearing line boring tool for an internal combustion engine with an aluminum head or a cast iron block with aluminum caps and an overhead camshaft with non-replaceable bearings that are cast in as an integral part of the cylinder head which utilizes a cutting bar formed with blind openings for receiving spring loaded cutters. Centering of the cutting bar is by the use of locating bushings selected to fit a plurality of different cam-oil-seal and/or oil-plug openings at either end of the cylinder head. The bushings remain in place during the line boring. Horizontal alignment is by alignment ears secured to the upper valve cover gasket surface. For long heads a center bar support is provided. Rotation of the bar is by a portable hand held drill.

An improved boring head assembly that is designed for being easily and accurately adjusted to different standard sizes of boring diameters so that it can be accomplished by persons without having a great deal of skill; the device consisting of a spindle for insertion into a chuck of a machine, and an adaptor adjustably mountable on the end of the spindle so to be axially offset a particular amount which is accomplished by means of specifically dimensioned blocks interchangeably placed therebetween, the adaptor serving to hold a boring bar which on its end retains a flying cutter.
摘要:
A boring tool is provided with a centering detector onto which a laser beam is directed. Deviation of the boring tool is detected and fed to a control unit and servo device which operates a pair of pusher pads to direct the boring tool back onto center. The boring tool is particularly adaptable for boring deep holes such as in large gun barrels.
摘要:
A drill collet or guide assembly for portable drill tools that rigidly locks the drill tool to a jig bushing in an aligned position to ensure accurate and rapid drilling of a plurality of aligned bores in a workpiece.
