Abstract
A template cutting device suitable for transferring onto a rotatable plain unworked template the lateral profile of a shaped sample piece that passes substantially perpendicularly to the device, which is specially suitable for use in machines which make shaped pieces in general and in which the profile is reproduced on a control cam or template. The purpose of the device is to manufacture control cams or templates and the like. The device includes structure for sensing the profile of the shaped piece when the former is moving crosswise to the latter; and a working group suitable for processing the plain, unworked template so as to obtain the control cam or template, whereby the forward movement of the sample piece controls the rotation of said unworked template.
Claims7
A template cutting device for transferring onto a template the lateral profile of an elongated shaped sample piece, comprising:
- frame means;
- a sensing device on said frame means including a support member supported for movement toward and away from said lateral profile on said sample piece;
- drive means on said frame means directly operatively drivingly engaging said sample piece to effect a movement of said sample piece relative to said frame means and substantially perpendicularly to the path of movement of said sensing device, said sensing device including a contour following member mounted on said support member and engaging said lateral profile of said sample piece;
- support means supporting said template for rotatable movement about a fixedly located axis in correspondence to the movement of said sample piece;
- and
- cutting tool means mounted on said support member and movable therewith in cutting relationship with a lateral edge of said template,
- whereby the movement of said sample piece controls the movement of said cutting tool means.
A template cutting device for transferring onto a template the lateral profile of an elongated shaped sample piece, comprising:
- frame means;
- a sensing device on said frame means including a support member supported for movement toward and away from said lateral profile on said sample piece, said sensing device including on one side thereof a free-wheeling wheel which is movable relative to said support member and engages the lateral profile of said shaped sample piece and on the other side thereof a force amplifier means, and including adjustment means for adjusting the relative positions of said sensing device and said force amplifier means;
- drive means on said frame means operatively drivingly engaging said sample piece to effect a movement of said sample piece relative to said frame means and substantially perpendicularly to the path of movement of said sensing device, said sensing device including a contour following member mounted on said support member and engaging said lateral profile of said sample piece;
- support means supporting said template for rotatable movement about a fixedly located axis in correspondence to the movement of said sample piece;
- and
- cutting tool means mounted on said support member and movable therewith in cutting relationship with a lateral edge of said template, whereby the movement of said sample piece controls the movement of said cutting tool means.
