Description
Technical field
The utility model relates to a kind of counter boring quality check tools.
Background technique
In aeronautical product manufacturing process, due to the particularity of aeronautical product, connection type is rivet or bolt
The connection type being spirally connected, especially when aerofoil class siding is connect with skeleton, for carried out after rivet drilling counter boring again riveting operation or
The operation that is spirally connected is carried out after bolt drilling counter boring.However during counter boring, the skill of the trueness error of socket drill and each worker
Can height, it is difficult to it is qualified to reach disposable counter boring, therefore need to be checked one by one with rivet or bolt counter boring quality and whether counter boring
In place, such mode working efficiency is lower, and without special inspection measurer, and participating in the rivet examined and bolt has inaccuracy
Property, management is extremely inconvenient, secondly, being interference engagement in fuel tank area connection rivet, checks counter boring quality with the rivet of standard
The precision of rivet hole will certainly be had an impact, the precision for eventually leading to rivet hole reduces, and is not able to satisfy the technology of product manufacturing
It is required that furthermore, counter boring quality is checked using common inspection rivet or bolt, existing will check rivet as standard rivet
It in product or checks that bolt is mounted on the risk on product as standard bolt, therefore a kind of convenience need to be designed and practical rivet nest
Checking tool.
Utility model content
The utility model aim is to overcome the deficiencies of the prior art and provide a kind of counter boring quality check tool.
The technical problem solved by the utility model is implemented by the following technical solutions:
A kind of counter boring quality check tool, including the preceding guide rod being fixedly connected and nose cone, the nose cone is back to preceding
One end of guide rod is equipped with lead screw, and the top of lead screw is equipped with size marking module, and the external activity of the nose cone is arranged with survey
The two sides set of amount set, measuring unit has graduation mark with it.
Further, the measuring unit is in the frusto-pyramidal configurations of lower open mouth, and measuring unit is consistent with the angle of taper of nose cone,
Be installed with adjusting nut among the upper surface of measuring unit, measuring unit by adjusting nut can up and down adjustment be mounted on lead screw.
Further, the length of the preceding guide rod is depending on the depth of gaging hole to be checked.
The utility model structure is simple, easy to operate, can be realized same diameter with the counter boring angle difference trade mark bolt and
The detection of the counter boring quality of rivet can accelerate self-test speed when rivet drilling counter boring or bolt drilling counter boring, meanwhile, and can
The phenomenon that evading wrong riveting, filling, and the design of the tool is simple, and manufacturing cost is low.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model preferred embodiment；
Fig. 2 is the side view of pressing plate in the utility model preferred embodiment；
Fig. 3 is the structural schematic diagram of measuring unit in the utility model preferred embodiment；
In figure, preceding guide rod 1, nose cone 2, lead screw 3, size marking module 4, measuring unit 5, adjusting nut 6.
Specific embodiment
In order to be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, under
Face combines and is specifically illustrating, and the utility model is further described.
Embodiment 1, referring to Fig. 1 --- counter boring quality check tool shown in Fig. 3 is divided into five effect partials, respectively
For preceding guide rod 1, nose cone 2, lead screw 3, size marking module 4 and movable measurement part, movable measurement part is wrapped again
Measuring unit 5 and adjusting nut 6 are included, measuring unit 5 indicates graduation mark in two sides；
Wherein, preceding guide rod 1 is the part cooperated with rivet hole or bolt hole, and length can be according to rivet hole or bolt hole
Actual depth determines；Nose cone 2 is consistent with standard countersunk head angle manufactured head or bolt head, for examining rivet nest or bolt nest
Counter boring quality；Lead screw 3 is portion of the handle, is put into taking-up and mistake proofing riveting, dress convenient for the instruments of inspection, improves working efficiency；Ruler
Very little labeling module 4 is the place of the instruments of inspection size marking, for the size of guide rod 1 before marking and the diameter of nose cone 2
And the angle of nest；Measuring unit 5 is in the frusto-pyramidal configurations of lower open mouth, and measuring unit 5 is consistent with the angle of taper of nose cone 2, measurement
Among the upper surface of set 5 be installed with adjusting nut 6, measuring unit 5 by adjusting nut 6 can up and down adjustment be mounted on lead screw 3；
With diameter with the bolt and rivet of the counter boring angle difference trade mark, corresponding counter boring depth is different, can be adjusted by adjusting nut 6
It fathoms.
Attached drawing 2 is counter boring quality check tool operation principle schematic diagram, in the actual operation process, according to rivet or spiral shell
The angle of the diameter and manufactured head of bolt, bolt head chooses nose cone 2, the drilling counter boring as requested on product, by inspection man
Tool be put into product counter boring, rotating adjusting nut 6, when the lower part of nose cone 2 cannot again toward decentralization when, can check nose cone 2 with
The compactness of counter boring reaches and quickly checks whether counter boring quality meets technical requirements；Still further aspect can also check counter boring
Specific quality set and counter boring overlapping position are observed and measured according to the graduation mark on measuring unit 5, read corresponding reading, so that it may
Know the specific depth of counter boring.
The basic principles and main features of the present invention and the advantages of the present invention have been shown and described above.Current row
The technical staff of industry is described in above embodiments and description it should be appreciated that the present utility model is not limited to the above embodiments
Only illustrate the principles of the present invention, on the premise of not departing from the spirit and scope of the utility model, the utility model is also
It will have various changes and improvements, these various changes and improvements fall within the scope of the claimed invention.The utility model
Claimed range is defined by the appending claims and its equivalent thereof.
