Abstract
This invention discloses a component marking device to allow components to be marked by using the rotation provided by a CNC type of machine or other machine tool, and which utilizes a stylus which shares the same approximate axis of rotation as the CNC machine and which utilizes rotating impact balls to impart a strong throwing force on hammer pins and a hammer to cause the sudden downward movement of the stylus as desired.
Claims5
A marking device for use with a CNC machine or other machine tool, comprising:
- a non-rotating housing;
- a stylus movably supported by the housing from a retracted position to an extended position;
- a stylus spring mounted relative to the stylus to move it to its retracted position;
- a machine spindle interface rotatably mounted to the housing and disposed to be rotated by a CNC or other machine tool;
- at least two impact balls rotatably supported within the housing and operatively attached to rotate with the machine spindle interface and about an axis of rotation of the machine spindle interface;
- a non-rotating hammer disposed at an upper end to be approximately simultaneously impacted by the at least two impact balls, and disposed at a lower end to drive the stylus to an extended position;
- and
- wherein the stylus is approximately co-axial with the machine spindle interface.
