Description

For detection of the cubing of the inclined hole degree of depth

Technical field

The utility model relates to a kind of depth detection instrument, especially for the cubing that detects the inclined hole degree of depth.

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 to detect. 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 measured hole depth, and a kind of cubing for detection of the inclined hole degree of depth providing.

To achieve these goals, the cubing for detection of the inclined hole degree of depth that the utility model is designed, it comprises gauge rod and is enclosed within the gauge block on gauge rod; The outer face of described gauge block is made up of a lower limit depth datum and upper limit depth datum, and angle between lower limit depth datum, upper limit depth datum, the upper surface of gauge rod and the angle of the horizontal plane face and the horizontal plane that all form with inclined hole to be measured equates; The lower limit depth datum of described gauge rod upper surface and gauge block is in same plane, the length of gauge rod is that gauge block lower limit datum level adds inclined hole set depth minimum of a value or peaked summation to the vertical range of gauge block lower surface, and the vertical range between described upper limit depth datum and lower limit depth datum equals inclined hole predetermined depth maximum and deduct the numerical value of minimum of a value; When measurement, gauge rod is inserted in through hole to be measured, then touch the outer face of gauge rod with hand, when touch, if gauge rod outer face and gauge block lower limit depth datum or upper limit depth datum are 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, guarantee later stage measurement effect, the lower end of described gauge rod is spherical in shape, and spherical contact-making surface is wider.

Compared with prior art, the cubing tool for detection of the inclined hole degree of depth that the utility model obtains has the following advantages:

1, by one high and one low datum level being set in gauge block upper surface, and on gauge block a sheathed gauge rod, by touch the upper surface of gauge rod with hand, judge and between gauge rod outer face and datum level, whether have difference in height, whether thereby it is qualified to judge exactly oblique through hole in workpiece for measurement,, be not easy to cause erroneous judgement, and efficiency is higher.

2、Simple in structure, cost is low, can extensively promote.

Brief description of the drawings

Fig. 1 is the view of cubing in the time detecting oblique through hole in embodiment.

In figure: face 31, holding screw 4 that gauge rod 1, gauge rod upper surface 11, gauge block 2, lower limit depth datum 21, upper limit depth datum 22, vertical through holes 23, horizontal thread hole 24, inclined hole form.

Detailed description of the invention

Below in conjunction with drawings and Examples, the utility model is further illustrated.

Embodiment:

The cubing for detection of the inclined hole degree of depth 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; The upper surface of described gauge block 2 is made up of a lower limit depth datum 21 and upper limit depth datum 22, and the face 31 that lower limit depth datum 21, upper limit depth datum 22, gauge rod upper surface 11 all form with inclined hole to be measured is parallel; The lower limit depth datum 21 of described gauge rod upper surface 11 and gauge block 2 is in same plane, the length of gauge rod 1 is that gauge block 2 lower limit datum levels 21 add inclined hole set depth minimum of a value or peaked summation to the vertical range of gauge block 2 lower ends, and the vertical range between described upper limit depth datum 22 and lower limit depth datum 21 equals inclined hole predetermined depth maximum and deduct the numerical value of minimum of a value; When measurement, workpiece for measurement is placed on a horizontal survey platform, gauge rod 1 inserts in inclined hole to be measured, then touch gauge rod upper surface 11 with hand, when touch, if the lower limit depth datum 21 of gauge rod upper surface 11 and gauge block 2 or upper limit depth datum 22 be in same plane, or during higher than lower limit depth datum 21 and lower than upper limit depth datum 22, the degree of depth of inclined hole is qualified; If gauge rod upper surface 11 is lower than lower limit depth datum 21 in the time touching, or during higher than upper limit depth datum, the inclined hole degree of depth is defective.
