The outside of guide rod is stated, the side of the bearing block upper end is provided with dial gauge, and the measurement end of the dial gauge is led perpendicular to described
Bar, the side of the bearing block lower end is provided with the first locking wrench, and one end of first locking wrench passes through screwed hole phase
It is butted on the guide rod.The guide rod as the dial gauge measure track, it is ensured that the stability of measurement data, improve survey
Accuracy of measurement, first locking wrench is used for the fixation of the bearing block, easy to use, reliable.
Preferably, the side of the bearing block upper end is additionally provided with the second locking wrench, the one of second locking wrench
End is mutually butted on the dial gauge through screwed hole, and second locking wrench is used for the fixation of the dial gauge, is easy to described hundred
Divide the regulation of table horizontal direction, it is simple to operate.
Further, the range of the dial gauge is 0-25mm, and measurement range is big.
Further, the dial plate of the dial gauge is set in vertical direction, and dial plate is outwardly directed, is easy in detection process
The jerk value of Real Time Observation hand of dial.
The beneficial effects of the invention are as follows：(1) by setting base and guide rod, and the guide rod is made perpendicular to the base,
The track that the guide rod is measured as dial gauge, it is ensured that detection process it is steady, improve accuracy of detection；(2) set described
First locking wrench and the second locking wrench so that detection process is simpler, easy to adjust, applied widely, input cost
Low, detection efficiency is high.
