Embodiment

Extremely shown in Figure 3 like Fig. 1; Mounting hole pick-up unit of the present invention; Have a base 10, this base 10 can be connected in the pedestal 80 that is used to support the location detected member, on base 10, has a datum hole 11; When base 10 is fixed on pedestal 80, the theoretical position of mounting hole of position and the detected member of this datum hole 11 is coincided.On base 10, connected a test section 32; This test section 32 can be with respect to the cofree in the horizontal direction slip of base 10; And be provided with a spliced eye 33 on the test section 32; When slip test section 32, can adjust this spliced eye 33 the position so that the axis of itself and datum hole 11 coincide.

Test section 32 specifically is connected on the base 10 by a slide assemblies; This slide assemblies comprises a transverse slider 20 that is arranged on base 10 tops; Be provided with guide rail 40 between transverse slider 20 and the base 10; Make transverse slider 20 to produce through this guide rail 40 and with respect to base 10 and slide, and on transverse slider 20, connected a longitudinal sliding block 30 through another guide rail, this longitudinal sliding block 30 can produce with respect to transverse slider 20 and slide; And glide direction is vertical with respect to the direction that base 10 slides with transverse slider 20, and test section 32 then is connected on the longitudinal sliding block 30.

Also be provided with the measurement mechanism of measuring spliced eye 33 on this device; This measurement mechanism comprises by two percentage gauge stands 22 and is connected in first dial gauge 71 on the base 10 respectively and is connected in second dial gauge 72 on the transverse slider 20; The measuring junction of first dial gauge 71 contacts with transverse slider 20; As first direction of measurement, the measuring junction of second dial gauge 72 contacts with longitudinal sliding block 30 with the direction of motion of transverse slider 20, it with the direction of motion of longitudinal sliding block 30 as second direction of measurement.Opposite end with corresponding dial gauge on the used percentage gauge stand 22 is provided with a boss 23, the sliding stroke of this corresponding transverse slider 20 of boss 23 restrictions and longitudinal sliding block 30, thus need not add extra stop means.

This device also comprises 50 and test pins 60 of a school zero pin; Carry out school zero with school 50 pairs of measuring mechanisms of zero pin earlier in use; Particularly; The axis of on transverse slider 20 and longitudinal sliding block 30, having offered zero hole 21, first school and zero hole 21, zero 31, the first schools, hole, second school respectively overlaps with spliced eye 33, school zero sell 50 pass spliced eye 33 successively, the zero hole 21, first school and second school are inserted in the datum hole 11 behind the zero hole 31; This moment, the reading with first dial gauge 71 and second dial gauge 72 was set at null value, promptly accomplishes the school odd-job of measuring mechanism is done.

After accomplished in school zero, high-ranking officers' zero pin 50 was extracted out from spliced eye 33, test pin 60 is inserted simultaneously in the mounting hole and spliced eye 33 of detected member; If mounting hole does not overlap with datum hole 11; It must make spliced eye 33 and datum hole 11 squint, and at this moment, the reading of dial gauge changes; Because before and the reading of dial gauge is set at null value, the side-play amount that therefore can directly read mounting hole.Through the data that on these two direction of measurement, record, can be used as the reference frame that improves the quality of production.
