[0023] As Figure 1 andFigure 2 The utility model discloses an outer circle grinding machine measuring arm, including measuring table 1, positioning piece 2 and measuring arm unit.

[0024] Specifically, the measuring active slot 3 is arranged through the measuring table 1, and the measuring active slot 3 is matched with the measuring arm unit.

[0025] The positioning piece 2 is fixedly arranged on the measuring table 1, and the positioning piece 2 is used for positioning and fixing the workpiece to be measured.

[0026] The measuring arm unit is movably arranged in the measuring active slot 3, and the measuring arm unit is used for measuring the outer diameter of the workpiece to be measured by tangential clamping.

[0027] In the embodiment, when the outer diameter of the workpiece to be measured is needed, the workpiece to be measured is placed on the positioning piece 2 for positioning and fixing. Then, the measuring arm unit is erected on the workpiece to be measured, and the measuring arm unit is tangent to the workpiece to be measured. Since the measuring arm unit has a fixed included angle, the outer diameter of the workpiece to be measured can be calculated according to the tangent value of the right triangle when the included angle vertex to the tangent point position is read from the measuring arm unit.

[0028] In an embodiment, the top end of the active slot 3 has a chamfer structure, and the inner wall of the active slot 3 is in sliding contact with the outer side wall of the measuring arm unit. The top end of the active slot 3 has a chamfer structure, which can guide the measuring arm unit to be quickly inserted into the active slot 3. In addition, the inner wall of the active slot 3 is in sliding contact with the outer side wall of the measuring arm unit, which can make the measuring arm be vertically inserted into the active slot 3, thereby ensuring the accuracy of the measurement result.

The distance between the included angle vertex and the tangent point can be quickly obtained by using the measuring scale 6, and the outer diameter of the workpiece to be measured can be calculated when the included angle is known.

[0032] If the measuring included angle is A, the length of the tangent point from the included angle vertex is B, and the radius of the workpiece to be measured is R, the outer diameter of the workpiece to be measured can be calculated according to the tangent value of the right triangle tanA / 2=R / B.
