When the auxiliary gauge of the tapered hole is used for testing, the contact surface between the gauge and the tapered hole is large, so that the rapid wear of the measuring hole surface can be prevented. The rapid and accurate measurement, and the good using effect are realized.
Description
Technical field
The utility model relates to the metering detection field, is a kind of bellmouth auxiliary detection tool specifically, is applicable to measure in the cylinder head bellmouth specified cross-section apart from the distance of bottom surface.
Background technology
In commercial production, some cylinder cap fuel injectors are arranged in the cylinder head bellmouth, need to measure the distance of bellmouth specified cross-section apart from the cylinder head bottom surface in installation process, adopt general measurer specified cross-section can't find, adopt three dimension coordinate measurement, if it is inadequate from top, hole built-in length to pop one's head in, can not measure, if probe enters from the hole end stretch, the bus of taper hole is too short, and measuring error is very large.Above-mentioned two kinds of methods can't realize at in-process measurement, impact processing, and quality can't guarantee.
Specifying conic section in bellmouth in measurement is exactly measuring basis, how to find measurement datum very important, directly on taper hole, looks for measuring basis very difficult.One is coaxially cut friendship with cylinder and the taper hole of specifying the conic section equal diameters in theory, and the cross section intercepted is exactly the measuring basis that will look for, and the measuring basis of cylinder head bellmouth is exactly desired measured value to the spacing of its bottom surface.Therefore need to provide a kind of durable and efficient bellmouth auxiliary detection tool, engagement height vernier caliper or lever indicator are used.
Summary of the invention
The durable and efficient bellmouth auxiliary detection tool that provides a kind of engagement height vernier caliper or lever indicator to use is provided technical problem to be solved in the utility model.
In order to achieve the above object, the technical scheme that the utility model adopts is:
A kind of bellmouth auxiliary detection tool, comprise positioning core axle and the fixing air plug gauge that thereunder length is definite value, described air plug gauge comprises a round platform seat and is fixed on the plug under the round platform seat, described round platform seat upper bottom surface is connected with positioning core axle, described round platform seat bottom surface is connected with plug, described round platform seat upper bottom surface diameter is greater than the diameter of bottom surface, described round table surface upper bottom surface diameter equals the diameter of tested bellmouth specified cross-section, and described round platform seat tapering is greater than tested bellmouth tapering.When cubing is put into to tested bellmouth, the round platform upper bottom surface contacts with tested bellmouth, determined measuring basis, below measuring basis, be the round platform that tapering is greater than tested bellmouth tapering slightly simultaneously, therefore round table surface can have face cooperation preferably to contact with tested taper hole, can prevent from measuring in use procedure to the taper hole surface damage.The air plug gauge length be comprised of round table surface and plug is definite value, cubing is put into to bellmouth adopts vernier height gauge or lever indicator measure-axis end face to arrive the distance of cylinder head bottom surface, if the plug end face exceeds the cylinder head bottom surface, actual range be air plug gauge length deduct the plug end face to the cylinder head bottom surface the distance after value, if plug end face and cylinder head bottom surface, actual range be air plug gauge length add the plug end face to the cylinder head bottom surface the distance after value.
More specifically, described round platform seat upper bottom surface diameter is 52mm.
More specifically, described air plug gauge length is 23.2mm.
More specifically, be provided with screw on described positioning core axle.
More specifically, described plug is shaped as column type.
The beneficial effects of the utility model are:
The utility model is comprised of positioning core axle and air plug gauge, and during test, cubing can have larger to contact with conical bore, can prevent the measured hole face than quick-wearing.During measurement because the air plug gauge length of putting into measured hole is certain value, adopt again vernier height gauge or the lever indicator measure-axis end face distance to the cylinder head bottom surface, can directly calculate the actual range of circular cone specified cross-section to the cylinder head bottom surface according to measured value.Adopt the auxiliary vernier height gauge of the utility model or lever indicator to measure spacing, result of use is good, and measurement fast, accurately.
The accompanying drawing explanation
Fig. 1 is the structural representation of a kind of bellmouth auxiliary detection tool of the utility model
In figure, positioning core axle 1, round platform seat 2, upper bottom surface 3, bottom surface 4, plug 5, screw 6, cylinder head 7.
Embodiment
Below in conjunction with 1 pair of the utility model of accompanying drawing, be described in further detail.
A kind of bellmouth auxiliary detection tool comprises the air plug gauge that positioning core axle 1 and fixing length thereunder are certain value as shown in Figure 1, above described positioning core axle 1, is provided with screw 6, for fixing the utility model position.Air plug gauge length described in present embodiment is 23.2mm, air plug gauge comprises a round platform seat 2 and is fixed on the column type plug 5 under round platform seat 2, the upper bottom surface 3 of described round platform seat 2 is connected with positioning core axle 1, the bottom surface 4 of described round platform seat 2 is connected with plug 5, described upper bottom surface 3 diameters are greater than the diameter of bottom surface 4, described upper bottom surface 3 diameters are designed to the diameter of tested bellmouth specified cross-section, present embodiment, for diameter in tested cylinder lid bellmouth is the distance of 52mm cross section to the cylinder head bottom surface, is designed to 52mm by the diameter of upper bottom surface 3.
When cubing is put into to cylinder head 7 bellmouth, upper bottom surface 3 contacts with the cross section that diameter in tested bellmouth is 52mm, has determined measuring basis.Described round platform seat 2 taperings are a bit larger tham tested bellmouth tapering, so round platform seat 2 and tested taper hole can have preferably face coordinate to contact, can prevent from measuring back and forth in use procedure to the taper hole surface damage.The air plug gauge length be comprised of round platform seat 2 and plug 5 is definite value simultaneously, after cubing is put into to tested bellmouth, adopt again vernier height gauge or the lever indicator measure-axis 5 end faces distance to cylinder head 7 bottom surfaces, if plug 5 end faces exceed cylinder head 7 bottom surfaces, cross-sectional distance bottom surface actual range be air plug gauge length deduct plug 5 end faces to cylinder head 7 bottom surfaces the distance after value, if plug 5 end faces and cylinder head 7 bottom surfaces, actual range be air plug gauge length add plug 5 end faces to cylinder head 7 bottom surfaces the distance after value.
In present embodiment, the diameter of the upper bottom surface 3 of positioning core axle 1 and round platform seat 2 all is set to 52mm, in actual the use, also the design of the diameter of positioning core axle 1 can be less than to the diameter of the upper bottom surface 3 of round platform seat 2.When the test other designated diameter the cross-sectional distance bottom surface apart from the time, the diameter setting of upper bottom surface 3 can be equaled to the diameter in taper hole to be measured cross section.While adopting the utility model device to test, cubing can have larger to contact with conical bore, can prevent the measured hole face than quick-wearing.During measurement, because air plug gauge length is certain value, only need again measure-axis 5 end faces to can be by calculating the demand actual range after the distance of cylinder 7 lid bottom surfaces, measure quick, accurate, result of use is good.
