Following steps:
1) clamping: the stub end of crankshaft forging to be measured (6) is penetrated in clamping cylinder (7), microcephaly's end-rack to auxiliary support mechanism (4)
Movable supporting arc (30) on；Rotate thread slider (9), under the action of screw thread thread slider (9) by lock cylinder (8) to folder cylinder
(7) direction promotes；The cambered surface for locking arc (15) at this time comes into contact with the inclined-plane on inclined-plane lock pillar (13), and by inclined-plane lock pillar (13)
And clamping column (11) is squeezed to the center position of lock cylinder (8), and collet (12) is finally made to clamp the major part of crankshaft forging (6) to be measured
End；Tighten the fastening bolt I (19) on movable sleeve I (16) and movable sleeve II (17)；
2) it transposes: selecting the detection block (22) of dimension and quantity according to the crankshaft forging to be measured (6) of different model size；It will
Detection block (22) is inserted in detection ruler (21), and the bottom end of detection block (22) faces crankshaft forging to be measured (6) vertically downward；Pass through inspection
Each detection block (22) are adjusted and arrive appropriately distance position by the specification of scale and crankshaft forging to be measured (6) in measurement ruler (21)；
Then fastening bolt II (25) is screwed in threaded securing bores II (24), until the front end face contact of fastening bolt II (25) detects
The top surface of ruler (21), to guarantee that every group of detection block (22) is fixed tight, and the top of the inner wall of sliding through hole (23) and detection ruler (21)
Portion's horizontal plane is bonded completely；Fastening bolt on movable sleeve III (20) is unscrewed I；Make testing agency (3) can be along support
Frame (5) freely moves up and down；
3) it detects: will test mechanism (3) and move down, touch the bottom of detection block (22) on crankshaft forging to be measured (6)
Corresponding test point；On the basis of the detection block (22) for touching test point at first by the first two, visually inspects or check it with clearance gauge
Gap between remaining one or more detection block (22) and corresponding test point, the straight line that maximum gap width measures required for being both
Degree；If you need to measure the straightness in crankshaft different angle, then the fastening bolt I (19) on movable sleeve II (17) can be unclamped；It holds
Anti-skid chequer (36) region on clamping studdle (10) simultaneously rotates clamping studdle (10), at this time can be by crankshaft forging to be measured
(6) it rotates together with, reaches the measurement for carrying out crankshaft forging straightness after being suitble to angle again.
