Acted on to the guide and limit of pin, add base inner circle and the bent axle cylindrical matching of microcephaly's axle journal, it is ensured that be of the present utility model steady
Property, the error produced during measurement is greatly reduced, so as to ensure that measurement result is accurate, improves certainty of measurement.
Advantage of the present utility model and feature, will carry out diagram reconciliation by the non-limitative illustration of preferred embodiment below
Release, these embodiments, be only given as an example referring to the drawings.
Brief description of the drawings
Fig. 1 is the structural representation that the utility model detects bent axle microcephaly's Woodruff key slots and keyways；
Fig. 2 is the A of Fig. 1 to amplification view.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples.
As depicted in figs. 1 and 2, the utility model include base 1, the first dial gauge 2, the first holding screw 3, guide finger 4,
Second dial gauge 5 and the second holding screw 6.Base 1 is sector, and base 1 is slidably supported on the microcephaly's axle journal of bent axle 7 upside, in it
Circle and the cylindrical matching of microcephaly's axle journal of bent axle 7, the position of base 1 are corresponding with 71 positions of microcephaly's axle journal upper semi-circle keyway of bent axle 7.100th
Table 2 is divided to be arranged on the upside of base 1, the lower end contact of the first dial gauge 2 passes perpendicularly through the middle part of base 1, with the microcephaly's axle journal upper half of bent axle 7
The bottom of round key groove 71 contacts, and the first holding screw 3 crosses the medial roof of base 1 on the lower end table bar of the first dial gauge 2.First percentage
The outside of table 2 is provided with guide finger 4, the surface hardening of guide finger 4 treatment, and the lower end of guide finger 4 passes perpendicularly through the middle part of base 1, small with bent axle 7
The two side mobile link of head axle journal upper semi-circle keyway 71.Second dial gauge 5 is arranged on the one end of base 1 outside, and the second dial gauge 5 is touched
Head is contacted horizontal through the one end of base 1 with the microcephaly's axle journal of bent axle 7 positioning end face 72, and the second holding screw 6 passes through the top of base 1
Withstand on the table bar of the second dial gauge 5.
The utility model detection method is as follows：
First calibrated before measurement, after the utility model is assembled, base 1 is supported on preprepared calibrated bolck, made
The contact of first dial gauge 2 is contacted with calibrated bolck upper semi-circle keyway bottom, while making the contact of the second dial gauge 5 and calibrated bolck locating surface
Contact, moves left and right the utility model, draws calibrated bolck upper semi-circle keyway depth and axial location dimensional standard value.
Then bent axle 7 is placed into stabilization, as shown in figure 1, the utility model base 1 is supported in the microcephaly's axle journal of bent axle 7
