Above-mentioned check-out console 3 comprises the go side end face 33 and the not-go-end end face 31 that are communicated with respectively at described mounting hole particularly, and described go side end face 33 is higher than described not-go-end end face 31, and offers grinding undercut 32 between described go side end face 33 and described not-go-end end face 31; The distance of the bottom surface of described base 1 and described go side end face 33 is greater than the altitude datum of Synchromous device of gearbox center to casing joint surface, and the distance of the bottom surface of described base 1 and described not-go-end end face 31 is less than described altitude datum; Like this, in testing process, if the end face of mandrel is between described go side end face 33 and described not-go-end end face 31, be that the end face of mandrel is lower than go side end face 33, and higher than not-go-end end face 31, Synchromous device of gearbox center is qualified to the height of casing joint surface, otherwise defective.Like this, be the benchmark of judgement setting, thereby be convenient to judge in testing process, simplified testing process.
It is pointed out that and be also not limited to the judgement that realizes by the way testing result, also can be by judging position and the distance relation judgement of plane on mandrel end face and check-out console 3.
As mentioned above, in height detection process, the bottom surface of base 1 need to fit with casing joint surface, the upper surface of base 1 need to fit with the bottom surface of mandrel 8, therefore the bottom surface of base 1 and the flatness of upper surface are had relatively high expectations, getting in the present embodiment flatness is 0.01mm, and the depth of parallelism of two planes is 0.01mm; Apparently, require as long as two surfaces of base 1 can meet flatness, be also not limited to above-mentioned concrete numerical value.
In order to ensure the connection reliability of base 1 and mandrel 8, and realize both detachable, base 1 can be fixedly connected with mandrel 8 by attachment screw 6; Apparently, it is fastening that base 1 and mandrel 8 are not limited to the mode being connected by screw, and also can adopt the conventional mode using in this area to realize both being fixedly connected with, such as bearing pin connection or clamping etc.
Can also be further improved to the cubing of casing joint surface height measurement Synchromous device of gearbox provided by the present invention center.
In above-mentioned embodiment, cubing provided by the present invention also comprises the overcoat 2 that is installed on described check-out console 3 lower surfaces, and described overcoat 2 is sheathed on described mandrel 8, and can slide axially along described mandrel 8.
Above-mentioned overcoat 2 is connected by trip bolt 4 with check-out console 3, and overcoat 2 and check-out console 3 can be free to slide along the outer wall of mandrel 8 as a whole, and overcoat 2 adopts clearance fit with mandrel 8, and suggestion adopts H7/g6.Apparently, overcoat 2 is also not limited to screw with the mode that is fixedly connected with of check-out console 3 and is connected, also can adopt this area conventional use other be fixedly connected with mode, such as clamping or bearing pin connection etc.
Further, in order to improve accuracy of detection, it is high that the flatness of the upper plane of overcoat 2 is wanted, and getting in the present embodiment flatness is 0.01mm.
In order to limit described overcoat 2 along described mandrel 8 sliding scale in the axial direction, avoid overcoat 2 to slide and excessively depart from mandrel 8, between overcoat 2 and mandrel 8, be provided with limiting component.
Particularly, described limiting component comprises the bar hole 9 that is opened in described mandrel 8, and is arranged at described overcoat 2 banking pin 5 in described bar hole 9 interior slips, limits the sliding scale of banking pin 5 by the hole wall of bar hole 9, can play position-limiting action.Apparently, the length of offering of bar hole 9 should be definite according to actual service condition, to ensure measurement range and to avoid overcoat 2 slippages to be as the criterion.
Above-mentioned limiting component is also not limited to the mode that above-mentioned bar hole 9 coordinates with banking pin 5, and for example, this limiting component can also be for being opened in overcoat 2 and the mandrel 8 spacing slide rail on both etc.
Between overcoat 2 and base 1, be provided with spring 7, described spring 7 is sheathed on described mandrel 8, and its upper end is fixed on described overcoat 2, and described base 1 is fixed in described lower end, to eliminate the deadweight of overcoat 2 and check-out console 3, handled easily personnel's operation.
Particularly, can offer mounting hole in overcoat 2 bottoms, spring 7 is arranged in this mounting hole, and is fixed on the end difference of overcoat 2 with its upper end.
Taking above-mentioned embodiment as example, sketch the testing process of cubing provided by the present invention below.
Taking following wheel box as example, the synchronizer width of this wheel box is 12.05 ± 0.02mm, and synchronizer center to the height dimension requirement of casing joint surface is
First the lower plane of overcoat 2 is leaned against in the upper plane that detects base 1;
The measuring junction 34 of check-out console inserts in synchronous tank, measuring junction 34 with synchronize tank clearance fit, synchronizer groove width is 12.05 ± 0.02, the width of measuring junction 34 is selected
in order to improve the precision of measurement, reduce measuring junction 34 and synchronize the gap of tank, this cubing can be manufactured to three groups, the measuring junction 34 of first group is of a size of
second group is
the 3rd group is
in use first use maximum one group, if can insert in synchronous tank, be just as the criterion with the detection data of this cubing, if can not insert, be replaced by the cubing of little a group;
Will height
as the diameter in a hole, by looking into handbook and calculating, the go side value of this measured size is
not-go-end value is
so the upper end face of mandrel 8 is till detect the bottom surface distance end value of base 1
the not-go-end of check-out console and the difference in height of go side are
Further, due to not-go-end and go side dimensional accuracy higher, need to carry out grinding to the not-go-end of check-out console and go side at this, so need to increase grinding undercut 32, facilitate the grinding of emery wheel.
In measuring process, when mandrel exceeds go side, illustrate that synchronizer center is less than normal to the height of casing joint surface, bigger than normal to the height of casing joint surface if mandrel lower than not-go-end, illustrates synchronizer center, if mandrel is between go side and not-go-end, highly qualified.
Only by the mode of explanation, some example embodiment of the present invention is described above, undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention in the situation that, can revise described embodiment by various mode.Therefore, above-mentioned accompanying drawing is illustrative with being described in essence, should not be construed as the restriction to the claims in the present invention protection domain.
