It slides and protrudes into slideway 4 in escape 3 and then the measuring rod 5 of the slot bottom of contact escape 3, the length of measuring rod 5 are measurement
The distance of slot bottom of the slideway outer end face of ontology 2 to escape 3, the slideway outer end face of ontology 2 are set when the depth of most shallow escape
There are connection slideway 4 and the depth stepped hole 6 equal with the tolerance of depth of recess, so that ontology 2 is contacted with part 1 and measuring rod
The depth of escape 3 is judged by judging whether the upper surface of measuring rod 5 is in stepped hole 6 when the slot bottom of 5 contact escapes 3
Whether degree is qualified.The depth gauge of the utility model, including ontology 2, slideway 4 and measuring rod 5.Ontology 2 with part 1 by connecing
Touching positions ontology 2, enables the escape 3 of 4 alignment element 1 of slideway.Measuring rod 5 can be slided in slideway 4 into
And protrude into the slot bottom of contact escape 3 in escape 3.The length of measuring rod 5 is that (i.e. depth is to allow to the most shallow escape of measurement
The escape of minimum limit value size) depth when ontology 2 slideway outer end face to escape 3 slot bottom distance, ontology 2
Slideway outer end face is equipped with connection slideway 4 and the depth stepped hole 6 equal with the tolerance of depth of recess.When the most shallow escape of measurement
Depth when, the upper surface of measuring rod 5 is flushed with the slideway outer end face of ontology 2；When (i.e. depth is to allow to the most deep escape of measurement
Maximum limit size escape) depth when, the upper surface of measuring rod 5 is flushed with the bottom surface of stepped hole 6.Measure withdrawing
It when the depth of slot 3, contacts ontology 2 with part 1 and the slot bottom of 5 contact escape 3 of measuring rod, passes through and touch or visual determination is surveyed
Whether the upper surface of gauge rod 5 is in stepped hole 6.Judged by judging whether the upper surface of measuring rod 5 is in stepped hole 6
Whether the depth of escape 3 is qualified, i.e., the upper end surface of measuring rod 5 is qualified in the depth for then indicating escape 3 in stepped hole 6,
It is on the contrary then indicate that the depth of escape 3 is unqualified.The depth gauge of the utility model can be convenient to the depth of escape 3 into
Row measurement, improves the detection efficiency of escape 3；The measurement of escape 3 suitable for like parts 1, it is versatile；Operation letter
Just, measurement is accurate.Optionally, measuring rod 5 is stretched out from the slideway outer end face of ontology 2, and measuring rod 5 is equipped with scale, passes through ontology 2
Slideway outer end face be compared to judge whether the depth of escape 3 qualified with scale.
As shown in Figure 3 and Figure 5, in the present embodiment, ontology 2, which has, to match with part 1 in order to be bonded the fitting of positioning
Face.Ontology 2 is bonded by binding face with part 1, prevents ontology 2 in measurement process from moving, it is ensured that the accuracy of measurement.
As shown in figure 3, the upper surface of measuring rod 5 and the slideway outer end face of ontology 2 are parallel, measuring rod 5 in the present embodiment
Upper surface is parallel with the bottom surface of stepped hole 6.Convenient for whether being in stepped hole by the upper surface of touch or visual determination measuring rod 5
In 6.
As shown in figure 3, being gap-matched between measuring rod 5 and slideway 4 in the present embodiment.Clearance fit can be reduced
Frictional force between measuring rod 5 and slideway 4 prevents measuring rod 5 from wearing during sliding in slideway 4.
As shown in figure 3, offering limiting slot 7 on measuring rod 5 in the present embodiment, ontology 2 is equipped with for across limiting slot
7 to the positioning pin 8 that measuring rod 5 limit and then prevents measuring rod 5 from deviating from out of slideway 4.Limiting slot 7 is along measuring rod 5
Length direction opens up, and after positioning pin 8 passes through limiting slot 7, measuring rod 5 can only slide in the length range of limiting slot 7.If surveyed
Gauge rod 5 continues to slide, the cell wall of limiting slot 7 will contact positioning pin 8, continue to slide to limit measuring rod 5, prevent measuring rod
5 deviate from out of slideway 4, and then measuring rod 5 is avoided to lose.
As shown in Figure 3 and Figure 4, in the present embodiment, measuring rod 5 is equipped with the bushing 9 for preventing measuring rod 5 from wearing.By
In there is 9 protection bar 5 of bushing, even if it is also that bushing 9 is worn that abrasion, which occurs, for measuring rod 5 and slideway 4, it is only necessary to the lining of abrasion
Set 9 is replaced, and compared to entire measuring rod 5 is replaced, cost is lower.Optionally, 9 thread bush of bushing is set on measuring rod 5.
As shown in figure 4, in the present embodiment, measuring rod 5 includes for protruding into escape 3 and then the slot of contact escape 3
The head 10 at bottom and shaft 11 for being slided in slideway 4.Shaft 11 slides in slideway 4, and head 10 is driven to protrude into
In escape 3 and then the slot bottom of contact escape 3 is to measure.
In the present embodiment, the length of head 10 is greater than the depth of escape 3.Even so that the depth of the most deep escape of measurement
When spending, head 10 also can contact to escape 3 slot bottom, it is ensured that measurement is gone on smoothly.
As shown in Figure 2 and Figure 4, in the present embodiment, the slot bottom of the measurement contact site and escape 3 of head 10 matches.
So that the measurement contact site of head 10 is bonded with the slot bottom of escape 3 when the slot bottom of 10 contact escape 3 of head, it is ensured that survey
Amount is accurate.Optionally, head 10 uses bulb, impaired to avoid contact, the service life of measuring rod 5 can be improved, while also avoiding
Damage the slot bottom of escape 3.Optionally, head 10 uses roll structure, and head 10 contacts use with the measurement of 3 slot bottom of escape
Cooperation is rolled, so that abrasion caused by reducing because of frequent contact, improves the service life of measuring rod 5.
As shown in figure 4, being equipped between head 10 and shaft 11 for being bonded with part 1 to avoid shock in the present embodiment
Part 1 causes the interconnecting piece 12 of damage.When the depth of escape 3 is greater than the depth of most deep escape, head 10 may be complete
Portion protrudes into escape 3, and shaft 11, which continues sliding, will strike part 1, can by the way that the interconnecting piece 12 being bonded with part 1 is arranged
To prevent measuring rod 5 impaired because hitting part 1.
The above descriptions are merely preferred embodiments of the present invention, is not intended to limit the utility model, for this
For the technical staff in field, various modifications and changes may be made to the present invention.It is all in the spirit and principles of the utility model
Within, any modification, equivalent replacement, improvement and so on should be included within the scope of protection of this utility model.
