Embodiment
A kind of crankshaft journal detection means, including calliper body 7, amesdial 1, gauge stand 4 and backplate 11；The calliper body 7
Bottom is square opening provided with a section, and the left side of calliper body 1 is card body 1, and right side is card body 26, the card body 1 and card
The middle part of body 26 is connected, and the top of connected component 12 sets and slit S is provided with above springhole F, springhole F, the connected component 12 with
Set between opening at elastic groove G, three faces of the opening and the point of contact of crankshaft journal and elasticity measurement point 13, footpath is respectively welded
To anchor point 14, fixed measuring point 15, in order to ensure to reduce elasticity measurement point 13, radial positioning point 14 in detection process, fix
The abrasion of measurement point 15, elasticity measurement point 13, radial positioning point 14, fixed measuring point 15 use special Hardmetal materials
It is made, in order to mitigate the weight of crankshaft journal apparatus for detecting diameter, the middle part of card body two, which is provided with, hollow removes repeated hole H；The card body 1
Top sets through hole, and amesdial cushion block 5 is plugged in the through hole, the end face of the amesdial cushion block and the gauge outfit of amesdial 1
Abut；Gauge stand 4 is fixedly connected with by screw at plane K on the card body 26, the front end of the gauge stand 4 is provided with connecting hole and lining
Set 3, the amesdial 1 is fixedly mounted on gauge stand 4 by lock-screw；The bottom of amesdial 1 is installed by amesdial protective cover
8, amesdial protective cover 8 is fixedly connected on bearing 10 by screw, and the bearing 10 is fixedly connected on calliper body 7 by screw
Two sides on；In order to prevent crankshaft journal apparatus for detecting diameter using process and people's Contact Temperature rise influence detection essence
Degree, the calliper body two sides are fixedly connected with backplate 11 by screw.
The present invention is before use, first wipe clean (crankshaft journal diameter design size) master body to table, a hand
By the backplate 11 of crankshaft journal apparatus for detecting diameter, fixed measuring point 15 is set to abut (the crankshaft journal diameter design chi to table
It is very little) master body axle journal side be caught in downwards, make radial positioning point 14 and the master body axle journal gentle touchdown to table.Make thousand
The gauge outfit of point table 1 is pressed on the front end face of amesdial cushion block 5 of crankshaft journal apparatus for detecting diameter, the registration of amesdial 1 effect to for
0。
When the present invention is used：
1st, tested crankshaft journal is wiped clean, crankshaft journal apparatus for detecting diameter is handled with care when using；
2nd, a hand takes the backplate 11 of crankshaft journal apparatus for detecting diameter, makes fixed measuring point 15 against crankshaft journal side
