摘要:
The machine comprises a sliding table (4) and a support (5,6) mounted on a transverse slide (1). The grinding spindle (7) is mounted on the support (5,6) by way of slide (14) which can be oriented by the slide (14) whereof the sliding plane of the slide is vertical and parallel to the axis of the grinding spindle (7) and whereof the sliding direction can be oriented in several positions. The grinding spindle (7) can also be oriented about an axis perpendicular to the slide (14).

摘要:
A scanning device for a machine for the automatic sharpening of broaching or reaming tools has a horizontal slide for receiving a tool to be sharpened and a vertical slide having at least one grinding spindle. A scanning finger which can be moved approximately vertically relative to the scanning device is provided for ascertaining the position of a particular tooth and is coupled with at least one member which emits displacement-dependent signals for triggering drive mechanisms for the machine slides. In order to enable a substantially arbitrary, yet precise, guidance of the scanning finger in order to ascertain dimensions which are of importance for the geometry of the tool, the scanning finger is attached on one of two slides which are displaceable at right angles relative to one another and a displacement pickup is associated with each slide for detecting the displacement distance from a position of rest traveled by respective slide.
摘要:
The invention is concerned with performing grinding operations on a workpiece at predetermined locations along its length and is described in connection with a machine for sharpening broaches in which a broach to be sharpened is mounted on a fixed bed, the positions of all the teeth on the broach are sensed by a probe during a first or forward pass of a work head along the whole length of the broach, the information so obtained is fed to a micro-processor and the broach teeth are sharpened in turn by a grinding wheel during a return pass of the work head along the broach using the information obtained by the sensing probe and input data fed initially into the micro-processor by means of a keyboard on a control panel.
摘要:
An attachment adapted to be mounted on the transverse carriage of a broach sharpener for movement toward and from the longitudinal axis of a broach supported on the longitudinally movable carriage of the sharpener, said attachment comprising a first part mounted on the transverse carriage for angular adjustment about a horizontal axis transverse to the longitudinally movable carriage, a second part slidably mounted on the first part for rectilinear movement along an axis corresponding to the angular adjustment of the first part, mechanism including a Scotch yoke interengageably connecting the parts operable to effect harmonic movement of the second part relative to the broach supported on the longitudinally movable carriage, said movable part mounting an electric motor, drive spindle and grinding wheel, and locking mechanism embodied in the drive operable to hold the second part at any given position to which it is moved throughout its permitted movement toward and from the longitudinal center line of the broach without drift.
摘要:
A scanning finger for a scanning device of a machine for automatically shening tools has a horizontal slide for receiving a tool to be ground and a vertical slide carrying at least one grinding spindle. The scanning finger has a scanning face, which is substantially horizontal and limited by and undercut to rest on the free face of a tool tooth to be ground, as well as a face which is downwardly offset from the scanning face and is intended for ascertaining the cutting face of the tooth. In order to make it possible to scan the cutting face at a distance from the original cutting edge, the face for ascertaining the cutting face of the tooth is undercut in the direction of movement of the horizontal slide and below the horizontal scanning face, and below the undercut it has a measuring edge to rest on the cutting face.
