Benefits of technology

The present invention provides an outrigger grinding fixture that is simple, inexpensive, and easy to use. It is designed to support a workpiece on a manual surface grinder with a worktable and grinding wheel. The fixture consists of a base member and a slide member with a V-shaped slot, which can be horizontally adjusted on the base member. The fixture also prevents vibration of the workpiece when the grinding wheel engages with it.

Problems solved by technology

When grinding a workpiece being a small part, there is a possibility that excessive heat will cause the workpiece to flex and become warped.
When the workpiece is not held securely, it can begin to vibrate, or chatter, and even break apart.
This results in a loss of materials and valuable time.
Furthermore, even though these innovations may be suitable for the specific individual purposes to which they address, accordingly, they would not be suitable for the purposes of the present invention as heretofore described.

Embodiment Construction

[0054]As shown in FIGS. 1 and 2, the present invention is an outrigger grinding fixture 110 to support a workpiece 112 on a manual surface grinder 114 having a worktable 116 and a grinding wheel (not shown). The outrigger grinding fixture 110 comprises a base member 118 maintained on the worktable 116. A slide member 120 has a V-shaped slot 122 formed on an upper edge 124. A mechanism 126 is for horizontally adjusting the slide member 120 on the base member 118. Another mechanism 128 is for preventing vibration of the workpiece 112 when the grinding wheel engages with the workpiece 112.

[0055]The worktable 116 and the base member 118 are both magnetic so that the base member 118 can be held in position on the worktable 116. The horizontally adjusting mechanism 116 comprises a dovetail tenon 130 formed on a top surface 132 of the base member 118. The slide member 120 has a mortise 134 formed on a lower edge 136 which engages with the dovetail tenon 130 of the base member 118 to allow ...

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims the benefit of Provisional Patent Application No. 613 / 63,298, filed on Jul. 12, 2010, In the United States Patent & Trademark Office, the disclosure of which is incorporated herein by reference.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to a manual surface grinder attachment, and more particularly, an outrigger grinding fixture.[0004]The outrigger grinding fixture is designed to provide support for a workpiece being a small part while machining. This ensures that the workpiece does not vibrate and break off. By supporting the end of the workpiece, it can be altered in size and shape without chatter or damage. The present invention can be used to support the workpiece in a manual surface grinder in any machine shop.[0005]2. Description of the Prior Art[0006]When grinding a workpiece being a small part, there is a possibility that excessive heat will cause the workpie...
