In the present embodiment, workpiece for measurement is back with cover 3, and 32 upper surface of BOSS column for defining back with cover 3 is measurement base
Directrix, 32 upper surface of BOSS column refer to the plane where the upper end of BOSS column 32.
Solid line d in Fig. 4 is the measuring basis line that the present embodiment obtains.
Tooling is measured when measuring the tooling parameter of workpiece for measurement, needs for workpiece for measurement to be mounted on profiling fixture, is imitated
Shape tooling is used to carry out profiling support to workpiece for measurement；Therefore, the structure and shape of profiling fixture should be with the knots of workpiece for measurement
Structure and shape match, so that workpiece for measurement to be mounted on profiling fixture, different workpieces for measurement corresponds to different profiling works
Dress.The workpiece for measurement of the present embodiment is back with cover 3, and back with cover 3 is domes, and the structure and shape of profiling fixture 2 are answered
The structure and shape with back with cover 3 matches；Therefore, the profiling support plate of profiling fixture 2 is domes.
Step (1) further includes tilting in the inclined slot 212 at both ends insertion 21 both ends of support base of back with cover 3
Gap 212 is fixed for cover to back 3, can be improved profiling fixture 2 and back with cover 3 be coupled it is secured
Property, profiling fixture 2 can be detached to avoid back with cover 3.
In step (1), the first limited post 25 is matched with the BOSS column 32 of back with cover 3, for carrying out to BOSS column 32
Limited support.The lower end of the BOSS column 32 of back with cover 3 is groove structure, and the first limited post 25 is contained in 32 lower end of BOSS column
In groove structure, for carrying out limited support to BOSS column 32, it is ensured that bolt is being connected and fixed extension gauge block 1, back band
When lid 3 and profiling fixture 2, BOSS column 32 will not be generated because of stress deformation or fracture the phenomenon that.
In step (1), the second limited post 26 is matched with the limit hole 34 of back with cover 3, is carried out for cover to back 3
Limited support.Second limited post 26 is inserted into the limit hole 34 of back with cover 3, carries out limited support for cover to back 3, can
With the fastness for improving profiling fixture 2 and back with cover 3 is coupled, profiling fixture 2 can be detached to avoid back with cover 3.
