Abstract
A toe clamp for a milling machine which comprises a T-nut slidable along an inverted T-shaped groove in the table top. A clamping screw is received in an inclined threaded bore in the T-nut for securing the nut in the groove. A work engaging member has a bore for receiving a shoulder bolt and the T-nut has a second threaded bore inclined at the same angle as the first threaded bore and receiving the threaded portion of the shoulder bolt. The work engaging member has a grooved edge for engaging with the edge of the work piece and the inclined shoulder bolt when tightened will force this grooved edge against the workpiece edge in an inwardly and downwardly direction for gripping it. The inclined clamping screw is received in a slot in the work engaging member to prevent it from rotating about the shoulder bolt.
Claims3
A toe clamp comprising:
- a. a nut slidable in an elongated groove in a milling machine table top, the groove having a cross section in the shape of an inverted T;
- b. a work engaging member having a bore downwardly inclined from the vertical and facing toward the adjacent edge of a work piece supported by the table top;
- c. a clamping screw having an upper portion received in said bore and a lower portion threaded into said nut, the head of said clamping screw moving said work engaging member downwardly and against the adjacent edge of the work piece when said clamping screw is tightened;
- and
- d. means for interconnecting said nut with said work engaging member and including a guide screw having its lower portion threaded into said nut and its upper portion received in an opening in said work engaging member that is slightly larger than the diameter of the guide screw, said guide screw's axis paralleling the inclined axis of said clamping screw.
