Portable device for machining a workpiece

A portable digitally controlled device for machining a workpiece, comprising

• a machining module;
• a clamping module for clamping the machining module to the workpiece, the clamping module comprising:
• means for removably attaching the clamping module to the workpiece,
• means for removably mounting the machining module to the clamping module;
• a flat frame adapted to be able to come at least partially to bear against an edge of the workpiece,
• wherein the means for removably attaching the clamping module to the workpiece comprise tightening means formed by means for positioning and pre-tightening the clamping module onto the workpiece and means for final tightening of the clamping module onto the workpiece,
• wherein the means for positioning and pre-tightening the clamping module onto the workpiece comprise a jaw formed by two tables extending parallel to each other, respectively fixed and mobile relative to the frame of the clamping module, the mobile table being slidably mounted on the frame and connected to means for actuating the mobile table to allow movement of the mobile table towards the fixed table while clamping the workpiece between them, wherein the means for actuating the mobile table comprises:
• a first lateral groove extending on one side of the frame of the clamping module and a second lateral groove extending on the other side of the frame of the clamping module,
• a first linear guide shoe carried by one lateral end of the mobile table and slidably housed in the first lateral groove and a second linear guide shoe carried by the other lateral end of the mobile table and slidably housed in the second lateral groove,
• a belt connecting each of the first and second guide shoes to an operating handle carried by the frame and configured to be movable from a first position wherein the belt extends so as to hold the mobile table at a predetermined distance from the fixed table to at least a second position wherein the belt exerts on the mobile table an action pulling the mobile table towards the fixed table so as to be able to clamp the workpiece between the fixed and mobile tables.
