PURPOSE:To facilitate the fitting and adjustment of a right angle block and eliminate the need for the skill of an engineer by fitting a right angle block used as a standard for correction of coordinates to an object-mounting table through an fitting base whose fitting position can be corrected. CONSTITUTION:This is an apparatus which makes it possible to correct the fitting position of a right angle block used as a standard for correction of the coordinates of a three-dimensional measuring machine employing a data processing system. For example, a right angle block 8 is first secured to a correcting base 9, and a guide hole 15' therein and a guide pin 15 of a fitting base 10 are fitted with each other. With a fixing screw 14 in a slot 17 loosened, a fine adjustment screw 12 attached to a side plate 11 is moved backward or forward so that the right angle block 8 is adjusted to a correct position and fixed to said position by using the screws 13 and 14. By using such as apparatus, it becomes exceedingly easy to fit and adjust the block, so that the need for the skill of an engineer is eliminated. |
