Abstract
The invention relates to a branch measuring device and a measuring method thereof, belonging to branch measuring technique field. The branch measuring device comprises an angle correction ruler with a ruler, and a height measuring ruler. The ruler is sleeved on the height measuring ruler. The lower portion of the height measuring ruler is provided with an arc positioning block vertical to the height measuring ruler. The arc positioning block is positioned on a platform. The measuring method comprises disposing the arc positioning block and the lower surface of the branch on the platform, jointing the arc surface of the arc positioning block with a flange excircle of the branch lower surface; sliding the ruler, jointing the angle correcting ruler with the branch upper surface, delimiting the included angle between the upper surface and the lower surface of the branch by using obliquity of the angle correction ruler, and determining distance between the center of the branch upper surface and the platform upper surface by using indication of the ruler on the height measuring ruler. Both the branch included angle and the branch height can be conveniently measured, and the invention is especially adaptive to uniform selection and matching of inlet branches during internal combustion engine maintenance and production.
Description
Technical field
The present invention relates to a kind of branch tube measuring apparatus and measuring method thereof, relate in particular to a kind of can with measurement of angle and highly measurement become the measurement mechanism and the measuring method thereof of one.
Background technology
Traditional measuring method owing to limit by the shape of air intake branch, can't be determined the apolegamy of the unified height of upper and lower surperficial angle of air intake branch and whole chassis air intake branch upper surface intuitively, after causing entrucking, air intake branch is uneven, and causes poor sealing easily, influences the quality that repairs.
Summary of the invention
Based on above-mentioned need of practice, the objective of the invention is to: provide a kind of and both can measure the arm angle, can measure again the arm height branch tube measuring apparatus.
Technical scheme of the present invention is: a kind of branch tube measuring apparatus, comprise the angularity correction chi that has scale, and height measuring rule, scale is sleeved on the height measuring rule, the height measuring rule below is provided with perpendicular arc locating piece, and the arc locating piece has placed on the platform.
Need to prove: the arm of measuring different angles need be selected the angularity correction chi with its equal angular for use.The structure of angularity correction chi itself is a prior art.The effect of platform is to be equivalent to a measuring basis face, and when measuring with assurance, the lower surface of arc locating piece and arm lower surface are in same plane, makes that measurement is more accurate.
Another technical scheme of the present invention is: the measuring method of described branch tube measuring apparatus places arc locating piece and arm lower surface on the platform, and the arcwall face of arc locating piece and the flange cylindrical of arm lower surface is fitted so that arm is located; Scale on the slip height measuring rule, and make angularity correction chi applying arm upper surface, the gradient of angularity correction chi is demarcated arm two surperficial angle angles up and down, to proofread and correct the upper and lower surperficial angle of arm, be used for determining the distance of arm upper surface center to the platform upper surface, i.e. a size by the indication of scale on height measuring rule.
Principle of work of the present invention: when measuring a collection of angle, select the angularity correction chi identical, and calculate the theoretical position of scale on height measuring rule by similar triangle theory according to the arm height with its angle angle with the identical arm of height design size.According to described measuring method arm is placed on the relevant position of described measurement mechanism again, slide scale, and make angularity correction chi applying arm upper surface.The arm upper surface if the angularity correction chi can not be fitted, that does not meet designing requirement with regard to the angle that arm is described; The arm upper surface if the angularity correction chi can be fitted, but the position of scale on height measuring rule do not overlap with theoretical position, and that height (being a size) that arm just is described does not meet designing requirement.
The invention has the beneficial effects as follows: not only can measure the arm angle easily,, also can be convenient for measuring the arm height, to proofread and correct the arm height to proofread and correct the upper and lower surperficial angle of arm.At the bend pipe of different angle angles, can measure as long as change the angularity correction chi identical with its angle.The present invention is used for building of diesel locomotive, not only can proofreaies and correct the upper and lower surperficial angle of air intake branch, can finish the apolegamy of the unified height of whole chassis arm again, guaranteed the sealing of general assembly (GA), improved the overhaul quality of locomotive.
The present invention is further described below in conjunction with the drawings and specific embodiments.
Description of drawings
Accompanying drawing is a structural representation of the invention process;
Reference numeral: 1 is the angularity correction chi, and 2 is height measuring rule, and 3 is scale, and 4 is the arc locating piece, and 5 is platform, and H is a size.
Embodiment
As shown in drawings, a kind of branch tube measuring apparatus, comprise the angularity correction chi 1 that has scale 3, and height measuring rule 2, scale 3 is sleeved on the height measuring rule 2, and scale 3 can slide up and down along height measuring rule 2, and height measuring rule 2 belows are provided with arc locating piece 4, height measuring rule 2 is vertical with arc locating piece 4, and arc locating piece 4 has placed on the platform 5.
The measuring method of described branch tube measuring apparatus places arc locating piece 4 and arm 6 lower surfaces on the platform 5, and the arcwall face of arc locating piece 4 and flange 7 cylindricals of arm 6 lower surfaces are fitted so that arm 6 is located; Scale 3 on the slip height measuring rule 2, and make angularity correction chi 1 applying arm 6 upper surfaces, the gradient of angularity correction chi 1 is demarcated arm two surperficial angle angles up and down, to proofread and correct arm 6 upper and lower surperficial angles, be used for determining the distance of arm 6 upper surface centers to platform 5 upper surfaces, i.e. a size H by the indication of scale 3 on height measuring rule 2.
Need to prove: though the foregoing description has been described structure of the present invention in detail; but the present invention is not limited to the foregoing description; the replacement structure that every those skilled in the art just can expect without creative work from the foregoing description all belongs to protection scope of the present invention.
