The right angle detecting device is described below with reference to fig. 1 to 4.
As shown in fig. 1 and 4, a right angle detecting device according to the present invention includes:
the workbench 1100, wherein the workbench 1100 is provided with a workpiece positioning strip 1120 and a positioning concave hole 1110 which are perpendicular to each other; the positioning concave hole 1110 is disposed at one end of the two workpiece positioning bars 1120 adjacent to each other.

It should be understood that, since the workpiece positioning bars 1120 are disposed at two sides of the positioning recess 1110 perpendicular to each other, when two sides of the workpiece contact the workpiece positioning bars 1120, the right angle of the workpiece will be suspended in the positioning recess 1110. At this time, the periphery of the right angle of the workpiece is not in contact with the workpiece positioning bar 1120 and the workbench 1100, so that burrs on the right angle do not affect the measurement result.
Therefore, the right angle of the workpiece is placed at the positioning concave hole 1110, so that the right angle of the workpiece is in a suspended state. At this time, when the side of the workpiece abuts against the workpiece positioning bar 1120, the measurement result is only affected by the contact surface with the workpiece positioning bar 1120. Therefore, by translating the measuring head 4150 along the workpiece locating bar 1120 to obtain the squareness data, the effect of burrs at the right angle can be eliminated to obtain the squareness of the workpiece, so that the measurement result of the squareness is more accurate.
