Abstract
Present invention teaches a magnetic pad to work with clamping tools where the magnet and protrusions on the top surface provide for easy aligning and connection from the clamping tool to the pad, relying primarily on the use of a ring-shaped magnet embedded in the top surface. The bottom surface provides flexible holding surface upon work pieces with two grooves of different sizes. The pad materials can be made from soft metals to eliminate marring the surface of work pieces.
Claims5
A die cast magnetic pad, comprising:
- a round disc having a top surface and a bottom surface;
- a ring-shaped permanent magnet embedded in a central portion of said top surface and is flush with a lower level plane within the top surface;
- a plurality of protrusions formed evenly spaced and next to an edge of the top surface, each of said protrusions contains an upper level tier flush with the edge of the top surface and a lower level tier flush with the lower level plane within the top surface and the embedded permanent magnet;
- and
- a first v-groove and a second v-groove set at a 90-degree relationship, with two grooves intersecting each other at a center point of the bottom surface of said round disc, wherein the first v-groove is wider than the second v-groove.
