Definitions

the present invention relates to lapping machines comprising an expansion cylinder, the piston of which is connected to the expansion rod of a lapping machine, means for detecting the position of the piston of this cylinder and providing an electrical signal which is a function of this position. , therefore the expansion of the lapping machine, and means for comparing this signal with a reference value and emitting, when this value is reached, a signal capable of stopping the movement of the piston.
the present invention relates to an honing machine perfected so as to allow compensation for wear of the lapping or a dimensional drift.
This lapping machine is characterized by the fact that it includes means for modifying the set value in the event of wear of the lapping or of dimensional drift.
the means for modifying the set value comprise an analog threshold voltmeter and means for varying the threshold of this voltmeter.
the means for varying the threshold of the voltmeter may include, for example, a digital up-down counter with manual display, a digital analog converter interposed between the counter and the voltmeter, and means for modifying the display of the counter as a function of '' wear of the lapping or the drift of dimension.
the means for varying the threshold of the voltmeter may also include a stepping motor, a control screw which is integral in rotation with the shaft of this motor but free in translation relative to it, and is mounted in a nut. fixed, an electronic probe which is controlled by the screw and connected to the voltmeter, and means for rotating the shaft of the stepping motor as a function of the wear of the lapping or of the dimensional drift.
a running-in head comprising an expansion cylinder body 1 which is integral with the piston 2 of a swing cylinder, only the lower end of this cylinder being shown.
the piston 3 of the expansion cylinder crossed by a spindle 4 whose lower part carries the lapping 5 and whose upper part is mounted in the body 1 by means of a bearing 6 and connected to pin 7 of the lapping machine.
the spindle 4 is itself crossed by an expansion rod 8 which carries the expansion cone 9 of the lapping 5 and which is secured in translation with the piston 3 by means not shown in the drawing.
a bracket 10 secured to the piston 3 of the expansion cylinder carries a pilot cam 11 which has the same profile as the expansion cone 9.
An intermediate feeler 12 is pivotally mounted at 13 on a support 14 fixed to the body 1.
This probe carries a shoe which is supported on the cam 11 and on which is supported the sensitive element of an electronic probe 15 having its body integral with the
