Torsion spring The probe of the comparator is placed on the measuring table, and the bottom is used to gently pull or pull the measuring frame to obtain the maximum change of the indicated value of the torsion comparator. The main body of the measurement is placed on the measuring slide, and the reflector is placed on the main slide. Move the main slide to the same direction, and obtain the maximum change of the indicated value of the collimator. Put the horizontal image on the main slide, and move the frame to obtain the maximum change of the indicated value of the collimator. The vertical direction: the meter is gradually installed on the measuring frame 1. After that, the u, two, 50m between the two spindles,A1), successively obtained 7(0emm original block, when slightly perturbed the original block, closed at the difference between the indications of points a and b. Pull direction: put the meter on the main slide, adjust the calibration level gauge main frame moving direction parallel (Figure A2), then move the meter frame along the calibration level gauge, so that the meter is back to the two axis one Rui, take the two changed indications, move 50m up along the axis, check again, take the difference between the two inspections, calibration level gauge

Micro-submerged tip column on the lathe between the upper and lower sections The length of the mandrel is 120mm and 300mm, and then the biopsy frame equipped with a micrometer is fixed on the frame in the reverse direction, so that the probe is directly connected to the mandrel and the two directions respectively! Figure): The upper and lower moving frame is inspected, and two force-up simple ratios are taken. The fire value of the cavitation quantity is shown in Figure A3
. The head of the meter is implanted with the outer surface of the rotation ratio, the rotating sleeve is rotated, and the torsion ratio is pressed according to the large-scale quality display disk
. Insert the mandrel in the cone of the frame, and the magnetic meter equipped with a lever is divided into the lower part of the meter. The frame is completed and the frame is moving: Figure A4), first connect with the spindle point a to get the indicated value, then rotate it 160°, and then connect with point b, cross the indicated value, and take the difference between the two indicated values
In the frame, install a 120-degree four-axis four-axis measurement on the top of the slide frame with a double-horn, and fix the torque gauge with the lower sub-meter on the rotating piano. The torque comparison value will be tested by the force method. The top of the cone will be touched with the top or bottom cone, and the torque comparison value will be taken. When the measuring slide is in the middle of the stroke, use the dynamometer to check and connect the corresponding indicator to the national inspection and calibration regulations. In the measurement frame, rotate the check and check between the two positions 70mm and 0mm at a time. Adjust the main slide frame to make the measuring shaft contact and enter the measurement state. Then tighten the slide frame, rotate the cam up and down several times to measure the original state, repeat the pressure measurement (not less than 10 times), and take the torque comparison number according to the maximum difference. tt||Inspection 1
