Patent GB-874817-A (GB)
Title: Contour measuring apparatus
IPC: G01B7/28
Filed: 1959-07-29
Abstract: 874,817. Gauging deviation from standard form. WARNER & SWASEY CO. July 29, 1959 [Aug. 7, 1958], No. 26054/59. Class 106 (2). Apparatus for gauging an object 1, comprises a gauging system 3, adapted when energized to move towards the object 1 being tested and to probe it, a tolerance measuring system, arranged to operate in synchronism with the gauging system and to indicate whether the object 1 conforms to a required tolerance, and a compensating mechanism 55 responsive to the probing and arranged to offset part of the tolerance measuring system in order to correct for the displacement from a reference position of the object being tested. The probe-holder 3 is driven forward by a motor 20, and a carriage 21 moves forward at the same time but at an increased rate. Tolerance bars 29-35 each move with the carriage 21 until the associated probe touches the workpiece 1, when a circuit is made energizing the corresponding solenoid 22 and so releasing a latch 36. The corresponding tolerance bar then remains where it is at that instant. The probes 4-11 are retractably mounted so that the holder 3 continues to move forward after the probe has touched the workpiece. When the carriage 21 is at the end of its travel, it actuates microswitches 75, 82, 83. Operation of switch 83 sets in motion a motor 74 driving a stylus carriage 50 carrying two sets of styli 71-73, 51-54. If the workpiece 1 is of the correct shape, the styli 71-73 contact conductive tolerance portions 44, 46, 48 on the bars 30, 32, 34 at the same time. These styli and the tolerance portions are wired in series as shown, so that a lamp 89 lights if the workpiece is correct as regards shape and is correctly placed. If the workpiece 1 is twisted or displaced in relation to its base 2, styli 51-54 which have been displaced accordingly, as described below, should contact similar tolerance portions 43, 45, 47, 49, simultaneously when the stylus carriage 50 reverses after travelling to the limit of its movement in one direction. If the blade is incorrect for any reason, the probes 4-11 go through a second operation, a recording apparatus being used to record the shape of the blade, as described in Specification 832,553. A bar 55 carrying the styli 51-54 is linked by rods 64, 65 to tolerance bars 29, 35 and the link is broken by solenoids 68, 69 when the switch 75 is operated. Thus, the bar 55 is set into a position corresponding to the twist of the workpiece when the holder 3 moves forward and remains in that angular position and moves with the carriage 50 when that is driven by the motor 74. Before gauging, a master workpiece is placed in position and the various tolerance portions 43-49 adjusted so that each is contacted by a stylus simultaneously. A similar apparatus may be used to gauge the other face of the workpiece 1.
