Abstract

A right angle touch gauge of the present application includes a fixing block, a floating column, a spring, a measuring column, a measuring sleeve and the like. In use, round head of top end of the floating column is in contact with bottom surface of work piece. The floating column is compressed downward when it touches high surface of the bottom surface of the work piece, the measuring column is compressed to right by matching lower cone of the floating column and left cone of the measuring column, and it may be found whether height difference between high surface and low surface of the bottom surface of the work piece is qualified by observing whether end edge of the right cylinder of the measuring column is placed between steps of right end surface of the measuring sleeve.

First claim

What is claimed is:

1. Right-angle touch gauge, comprising: a fixing block, a floating column, an upper screw, an upper spring, a measuring column, a lower spring, a measuring sleeve and a lower screw, lower cylindrical portion of the floating column is matched with a vertical hole in the fixing block, the upper screw is fixed to left side of the fixing block, and top end thereof is matched with a slot in the floating column, the upper spring is sleeved on outer side of cylinder of the floating column, and is placed above the fixing block, left cylinder of the measuring column is matched with a transverse hole of the fixing block, the lower screw is fixed in lower portion of the fixing block, and top end thereof is matched with a slot in the measuring column, the measuring sleeve is fixed to right side of the fixing block and is matched with right cylinder of the measuring column, the lower spring is sleeved on right cylinder of the measuring column, and is placed on left side of the measuring sleeve, top end of the floating column is a round head and bottom end of the floating column is a 45 degree cone;
left side of the measuring column is a 45 degree cone, and edge of right side is kept at a sharp angle, cone of lower end of the floating column is matched with left cone of the measuring column, edge of an inner hole of the measuring sleeve is kept at a sharp angle.
