Abstract
The utility model discloses a special detection tool for length of a first spindle journal of a crankshaft, which comprises an annular frame with a boss. A handle is arranged on the annular frame, a hole is further arranged on the annular frame, and a dial gauge rod penetrating through the hole is positioned by a locking screw. The special detection tool solves the problem of large measurement error of the prior art, and has the advantages of convenience and accuracy in detection and simple structure.
Description
One, technical field
The utility model relates to the engine component testing tool, is specifically related to a kind of bent axle first king journal length special detection tool.
Two, background technology
Bent axle is the vitals of engine, and therefore, in the production run of bent axle, the multi-cylinder bent axle first king journal length requirement again is strict especially.At present, the bent axle first king journal testing tool mainly is to be used in branch chi and point micrometer.These detecting instrument efficient are low, and equipment investment is big, and the incompatible full inspection of detection efficiency needs.In the actual production testing process, checker, operative employee, inspector need cubing, and the fast investment of cubing consumption is big, and the new worker is difficult for association, and the uneven measuring error of exerting all one's strength is big, and these reasons have restricted production, have reduced throughput rate.
Three, summary of the invention
Technical problem to be solved in the utility model provides a kind of bent axle accurately easy to detect first king journal length special detection tool.
For solving the problems of the technologies described above, the bent axle first king journal length special detection tool of the present utility model comprises the annular frame that has boss, and this annular frame is provided with handgrip, also be provided with a hole on the annular frame, the dial gauge bar passes this hole and is located by lock screw.
Because technique scheme adopts the annular frame that has boss, annular frame is provided with handgrip, also is provided with a hole on the annular frame, and the clock gauge bar passes this hole and located by lock screw.With the utility model prior to the standard component calibration after, detect to be checked again, be easy to obtain the bent axle first king journal length tolerance numerical value from dial gauge.Therefore, the utlity model has accurate and characteristic of simple structure easy to detect.
Four, description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the utility model user mode synoptic diagram.
Five, embodiment
As seen from Figure 1, the bent axle first king journal length special detection tool of the present utility model comprises the annular frame 1 that has boss, and this annular frame 1 is provided with handgrip 2, also is provided with a hole on the annular frame 1, and dial gauge 3 bars pass this hole and located by lock screw 4.
Referring to Fig. 2, using method of the present utility model is as follows:
1, his-and-hers watches.To carry out the his-and-hers watches adjustment to dial gauge before using, the diameter of axle of annular frame 1 inside surface and standard component is fitted, move the close standard component outer face of the raised head face that makes annular frame 1 with hand 2, dial gauge 3 is near the standard component raised head face, the pointer of adjusting dial gauge 3 arrives zero-bit, and makes the range of table that certain decrement be arranged.
2, measure.Annular frame 1 inside surface and bent axle first main shaft 5 footpaths are fitted, move close bent axle first main shaft 5 outer faces of the raised head face that makes annular frame 1 with hand 2, dial gauge 3 is near bent axle first main shaft 5 raised head faces, at this moment, the pointer of dial gauge 3 demonstrates numerical value, is the numerical value of the bent axle first king journal length tolerance.
Claims (1)
