Abstract
A special measuring tool for measuring aperture of stepped holes resolves the technical problem that production cost is increased due to complicated measurement steps for inner diameter and outer diameter of stepped holes in the prior art. The technical scheme includes that the special measuring tool is provided with a main scale and a vernier which are in horizontally sliding matching via a slide groove, the main scale is provided with a main scale lever, the vernier is provided with a square lever, and the main scale and the vernier are arranged between the main scale lever and the square lever to form a measuring arm structure with symmetrical profile. The special measuring tool has the advantages that the size of the aperture of the stepped holes can be measured easily by means of matching the vernier with the main scale having fixed measuring scale marks, thereby not only saving production cost, time and labor but bringing convenience for carrying.
Description
Technical field
The utility model relates to a kind of survey instrument, is applied to shoulder hole diameter measurement field, particularly a kind of easy to carry, accurate shoulder hole diameter special measurement instrument of measurement.
Background technology
In the machining engineering; usually have the processing of shoulder hole; as engine cylinder-body, cylinder cap etc.; the measurement of hole depth mainly is to use vernier caliper, and when measuring the shoulder hole diameter, because these shoulder holes are normally conical in the bottom; the instrument and the operation steps that just need more complicated; purchasing of these instruments both increased production cost, takes time and effort again, and large-scale surveying instrument also is not easy to carry simultaneously.At above problem, prior art does not well solve, and has brought trouble for the work of this area.
Summary of the invention
The utility model is for solving the loaded down with trivial details technical barrier that causes increasing production cost of ladder aperture measuring process, the utility model has designed a kind of ladder aperture special measurement instrument, by vernier scale and the cooperation that has the main scale of fixation measuring scale, can measure the size in the inside and outside footpath of shoulder hole easily.
The utility model for realizing the technical scheme that goal of the invention adopts is, a kind of ladder aperture special measurement instrument, the structure of special measurement instrument is that the main scale that is provided with the main scale handle forms being slidingly matched of horizontal direction by chute and the vernier scale that is provided with the try square handle, and above-mentioned main scale and vernier scale are arranged between main scale handle and the try square handle, formation body symmetrical expression gage beam structure.
The beneficial effects of the utility model are: by the cooperation of vernier scale and main scale, can measure the size in the inside and outside footpath of shoulder hole easily, both save production cost, and time saving and energy saving again, be easy to carry.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
In the accompanying drawing, the 1st, main scale, the 2nd, vernier scale, the 3rd, holding screw, the 4th, main scale handle, 4-1 are card bases, the 5th, try square handle, 5-1 are card bases.
Embodiment
Referring to accompanying drawing, a kind of ladder aperture special measurement instrument, the structure of special measurement instrument is that the main scale 1 that is provided with main scale handle 4 forms being slidingly matched of horizontal direction by chute and the vernier scale 2 that is provided with try square handle 5, and above-mentioned main scale 1 and vernier scale 2 are arranged between main scale handle 2 and the try square handle 5, formation body symmetrical expression gage beam structure.
Above-mentioned main scale handle 4 is respectively arranged with notch cuttype card base 4-1,5-1 with try square handle 5 lower ends.
The measuring accuracy of above-mentioned special measurement instrument is 0.02mm.
Above-mentioned special measurement instrument according to the scope in ladder aperture set the length of main scale 1 or try square handle 5, to constitute the series of combination survey instrument.
The utility model according to the inside and outside footpath of the shoulder hole of different range, can stipulate to make the length of main scale 1 and try square handle 5 in the specific implementation, forms the special measurement instrument of a series.The utility model is when concrete the measurement, and minimum measured value fixedly installs, and when the measured hole electrical path length, at first reads the reading on main scale 1 and the vernier scale 2, with minimum measured value addition, then is the length of target aperture then.When concrete operations, at first two card base 4-1,5-1 on main scale handle 4 and the try square handle 5 are stuck on the ladder platform at maximum inner diameter place in the shoulder hole, in case in measuring process, the survey instrument skew back causes measurement data inaccurate; Then holding screw 3 is tightened, taken out ruler, read registration.
