Description
Technical field
The invention belongs to mechanical processing technique technical field, relate to a kind of survey instrument, specifically relate to a kind of aperture hole depth measurement mechanism.
Background technology
Along with the development of aero engine technology, new machine development rhythm is more and more faster, often occurs that special tooling can not offer manufacturing department in time in parts machining, causes manufacturing schedule to be obstructed, and processes discontinuous situation.Aircraft engine accessory casing belongs to box parts, on part, there is a large amount of holes to need processing, and aperture size is inconsistent, hole depth range of size is larger, depth size adopts three use vernier calipers or vernier depth gauge to measure conventionally at present, but three use vernier calipers can only be measured aperture and be greater than part more than φ 4mm, the aperture that is less than φ 4mm for aperture adopts special tooling to measure conventionally, special tooling is as a kind of specific purpose tool, do not there is versatility, in this case, be badly in need of one simpler, more general instrument is processed dimensional data is more accurately provided for part.
Summary of the invention
The invention provides a kind of aperture hole depth measurement mechanism, thereby reach the effect of accurate measurement and convenient and general.
The present invention is achieved by following technical solution.
A kind of aperture hole depth measurement mechanism, comprise sounding rod, positioning adapter, standard gauge rod, gauge rod cover, nut, lock-screw, trip bolt and secondary chi, described gauge rod cover is hollow structure, one end is processed with step, described standard gauge rod is arranged in the cavity of gauge rod cover, one end attaching nut, the other end connects sounding rod, described positioning adapter center is processed with aperture, make sounding rod pass aperture, the step end that positioning adapter is sleeved on to gauge rod cover, described gauge rod puts and is processed with one section of flat structure of milling, and described secondary chi is fixed in flat of milling by trip bolt.
On described secondary chi, there is the master scale line of 20 calibration.
In flat of the milling of described gauge rod cover, there is bar hole.
Described standard gauge rod is the flat structure of milling, in flat of milling, has master scale chi scale mark.
Scale mark overall length on described standard gauge rod is 70mm.
Described standard gauge rod can be free to slide vertically in gauge rod cover.
Between described sounding rod and standard gauge rod for being threaded.
The invention has the beneficial effects as follows:
A kind of aperture hole depth measurement mechanism of the present invention, by by the accurate rule scale of the standard gauge rod one side flat rear bidding of milling, and be assembled in gauge rod cover, then, by elongated shape sounding rod, stretch in hole in piece part and measure, coordinate and carry out reading with the scale on standard gauge rod by vernier, reached the effect that accurately measures little hole depth, the technical program can also be general during the hole depth to other various models measures, simple in structure, measure accurately highly versatile.
