With the development of science and technology, the progress of technology and the innovation of products, especially as the main component of the automobile body, the stability of the shape and size directly affects the precision of the automobile body, so the bolt end surface perpendicularity must be controlled within the tolerance range. Due to the poor consistency of the bolt, the editing of the measurement program is affected, so the bolt needs to be manually measured before measurement. The perpendicularity of the assembly flange surface of the flange bolt has been a problem for people in the detection process, and the existing detection means mostly adopts three-coordinate manual point detection.

[0050] Loosen the third locking bolt 12, press the tail of the long dry part of the L-shaped compression block 11, make the gap between the L-shaped compression block 11 and the V-shaped part of the long V-shaped iron 10 larger, place the measured bolt 18 on the auxiliary supporting block 16, limit the Z direction movement of the measured bolt 18 through the auxiliary supporting block; tighten the third locking bolt 12, press the measured bolt 18 to the V-shaped part of the long V-shaped iron 10 through the L-shaped compression block 11, limit the X, Y direction movement and X, Y, Z rotation of the measured bolt 18;

[0051] The measured bolt 18 in the embodiment is for the bolt with a flange, and the flange is smooth without an anti-loosening inverted cone.

[0052] Step two: adjustment of the measuring device;

[0053] Adjust the bidirectional adjusting slider 5 to drive the L-shaped square ruler 8 to move, make one end of the L-shaped square ruler 8 lap to the root of the assembly conical surface of the measured bolt 18, lock the X direction movement of the bidirectional adjusting slider 5 through the first locking bolt 4, adjust the micrometer 6 to zero, and fasten the micrometer 6 through the second locking bolt 2 to make the indication of the micrometer 6 stable;

[0056] The requirement of the bolt perpendicularity is different for different purposes, and the general accuracy level of the requirement of the symmetry is 0.10 mm, when the measured value is less than the requirement value of the perpendicularity, it is determined to be qualified, such as less than 0.10 mm, when the measured value is greater than the requirement value of the perpendicularity, it is determined to be unqualified, such as greater than 0.15 mm. The symmetry is measured by using the three coordinates, and the preparation time, the sampling time and the evaluation time are added together to be close to half an hour, and because the requirement of the bolt symmetry is the waste of the precision measuring equipment resources for the precision of the three coordinates; by using the measuring device related to the application, the measurement can be completed in several minutes in the ideal state, and the measurement efficiency is greatly improved.
