Description
Technical field
The utility model relates to a kind of depth detection instrument, particularly oblique via depth cubing.
Background technology
At machinery production manufacture field, conventionally need boring. In order to ensure installing closely between parts, must guarantee the degree of depth in hole within the limits prescribed. Therefore, need to detect the degree of depth in hole. Conventionally, the detection mode of the inclined hole degree of depth is to use high-precision three-dimensional detector. But this metering system, not only need to expend the longer time, and three-coordinate instrument is expensive, general enterprise can not accept. And common scale cubing, whether judgement product depth that can not be succinct is qualified.
Summary of the invention
The purpose of this utility model is that to measure cubing testing tool cost high in order to solve existing hole depth, and detection time is long, meanwhile, can not measure the whether problem in the margin of tolerance of the measured spark-plug hole degree of depth, and the oblique via depth cubing of the one providing.
To achieve these goals, the oblique via depth cubing that the utility model is designed, it comprises gauge rod and is enclosed within the gauge block on gauge rod; The upper surface of described gauge block is parallel with the face that oblique through hole to be measured forms, and the outer face of described gauge rod is datum level, is made up of a lower limit depth datum and the depth datum of reaching the standard grade; The minimum of a value that described lower limit depth datum, the depth datum of reaching the standard grade are respectively through hole working depth to the distance of gauge rod bottom adds the summation of gauge block height, the summation that through hole working depth maximum adds gauge block height, and lower limit depth datum and the difference in height of reaching the standard grade between depth datum are the tolerance value of through hole to be measured; When measurement, first band measuring workpieces is placed in detection platform, again gauge rod is inserted in through hole to be measured, and be inserted in gauge block, and the lower surface of gauge block and workpiece upper surface are close to, then touch the outer face of gauge rod with hand, when touch, if gauge rod lower limit depth datum or upper limit depth datum and gauge block outer face be in same plane, or during higher than lower limit depth datum and lower than upper limit depth datum, the degree of depth of through hole is qualified.
Further, be provided with a vertical through holes for sheathed gauge rod at gauge block middle part, be provided with a horizontal thread hole being connected with vertical through holes in a side of gauge block, be provided with a holding screw at horizontal thread hole place, be provided with a blind hole matching with holding screw at the side of gauge rod, longitudinal width of described blind hole is greater than longitudinal width of holding screw.
Further, in order to make the lower end of gauge rod touch the bottom of detection platform completely, the lower end of described gauge rod is spherical in shape.
Further, in gauge rod upper end, lower limit depth datum and reach the standard grade and be provided with a vertical groove between depth datum, the transverse width of described vertical groove is between 3 ~ 10mm.
Compared with prior art, the oblique via depth cubing tool that the utility model obtains has the following advantages:
1, by one high and one low datum level being set in gauge rod outer face, and by touch this datum level with hand, judge between datum level and gauge block outer face whether have difference in height by sense of touch, whether thereby it is qualified to judge exactly oblique through hole in workpiece for measurement, survey tool before comparing, its measuring method is easier, measures efficiency higher.
2, by gauge block is set on gauge rod, and the upper surface of gauge block is paralleled with the face that oblique through hole to be measured forms, the lateral surface that can avoid closing on through hole upper end is not plane or while having other projecting member to block, the situation that inconvenience touches.
Brief description of the drawings
Fig. 1 is that in embodiment, cubing is inserted view when inclined hole to be measured is interior to be detected.
In figure: gauge rod 1, lower limit depth datum 11, the depth datum 12 of reaching the standard grade, blind hole 13, vertical groove 14, gauge block 2, gauge block upper surface 21, vertical through holes 22, horizontal thread hole 23, holding screw 3.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Embodiment:
The oblique via depth cubing that the present embodiment provides, as shown in the figure, it comprises gauge rod 1 and is enclosed within the gauge block 2 on gauge rod 1; Described gauge block upper surface 21 is parallel with the face that oblique through hole to be measured forms, and the upper surface of described gauge rod 1 is datum level, is made up of a lower limit depth datum 11 and the depth datum 12 of reaching the standard grade; Described lower limit depth datum 11 adds that with the minimum of a value of oblique through hole working depth the summation of gauge block 2 height equates to the distance h 1 of gauge rod 1 bottom, the depth datum 12 of reaching the standard grade adds that with through hole working depth maximum the summation of gauge block 2 height equates to the distance h 2 of gauge rod 1 bottom, and lower limit depth datum 11 and the difference in height of reaching the standard grade between depth datum 12 are the tolerance value of through hole to be measured; When measurement, first band measuring workpieces is placed in detection platform, again gauge rod 1 is inserted in through hole to be measured, and be inserted in gauge block 2, and the lower surface of gauge block 2 and workpiece upper surface are close to, then touch the outer face of gauge rod 1 with hand, when touch, if gauge rod 1 lower limit depth datum 11 or upper limit depth datum 12 is with gauge block upper surface 21 in same plane, or during higher than lower limit depth datum 11 and lower than upper limit depth datum 12, the degree of depth of inclined hole is qualified; Otherwise, if in the time touching gauge rod 1 lower than lower limit depth datum 11, or during higher than upper limit depth datum 12, the inclined hole degree of depth is defective.
In the present embodiment, be provided with a vertical through holes 22 for sheathed gauge rod at gauge block 2 middle parts, this through hole 22 is slightly larger than the external diameter of gauge rod 1, be provided with a horizontal thread hole 23 being connected with vertical through holes 22 in a side of gauge block 2, be provided with a holding screw 3 at 23 places, horizontal thread hole, be provided with a blind hole 13 matching with holding screw 3 at the side of gauge rod 1, longitudinal width of described blind hole 13 is greater than longitudinal width of holding screw 3.
As optimization, in order to make the lower end of gauge rod 1 touch the bottom of detection platform completely, the lower end of described gauge rod 1 is spherical in shape, and spherical contact-making surface is more, more easily touches detection plane.
As optimization, at gauge rod 1 upper end, lower limit depth datum 11 with reach the standard grade and be provided with a vertical groove 14 between depth datum 12, the transverse width of described vertical groove 14 is between 3 ~ 10mm. This groove 14 can separate lower limit depth datum 11 and the depth datum 12 of reaching the standard grade, in the time touching, and more easily judgement.
Finally it should be noted that, above embodiment is only in order to the technical solution of the utility model to be described but not restriction technologies scheme, although applicant has been described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, those are modified to the technical solution of the utility model or are equal to replacement, and do not depart from aim and the scope of the technical program, all should be encompassed in the middle of claim scope of the present utility model.
