Abstract

The utility model relates to an utensil is surveyed to high accuracy diameter should possess including support A, support B, table skeleton, percentage table, adjusting screw, opening cover, round pin and screw in the survey, support A and support B be the both ends of " eight " font form slope symmetry setting at the table skeleton through round pin and screw, the percentage table passes through adjusting screw and the opening cover sets up the intermediate position at the table skeleton. The utility model has the advantages of simple and reasonable structure, it can be satisfied and measuring major diameter size part batch production outside diameter detection performance requirement especially is difficult to to cylinder class part diameter, and precision height, convenient operation, with low costs.

Description

Diameter measuring tool in high precision
Technical field
This utility model relates to a kind of measuring tool, a kind of high accuracy diameter measuring tool.
Background technology
Along with science and technology and expanding economy, the technology of China's mechanical manufacturing field is also the most progressive, some parts with high content of technology appearances the most in succession of the thing followed, precision and the prescription of its processing the most constantly improve, the past traditional method by testing staff's visual detection workpiece quality cannot adapt to the needs of above-mentioned new situations, being badly in need of one on market and have accuracy of detection height, error is little, reproducible Special diameter measuring tool.
Some machinery important spare part diameter dimension is relatively big, and diameter dimension tolerance precision is higher, and therefore, the detection of diameter dimension just becomes the pith ensureing workpiece quality.
Traditional diameter detection method is to take multiple measurements with slide gauge to average, and is that measurement time visual error longer, inspectoral is bigger in place of the shortcoming and defect of the method.Especially major diameter parts batch is extremely inefficient with vernier caliper measurement when producing.
Summary of the invention
The purpose of this utility model is to provide for a kind of high accuracy diameter measuring tool, this measuring tool is simple and reasonable, disclosure satisfy that it especially meets the major diameter dimension parts batch being not easy to measure and produces the detection performance requirement of external diameter Cylinder Parts diameter, and precision is high, easy to operate, low cost, it is possible to enterprise economic benefit.
The purpose of this utility model is realized in, this measuring tool includes support A, support B2, dial framework, dial gauge, adjustment screw, opening sleeve, pin and screw, described support A and support B is that "eight" shape shape tilts to be symmetricly set on the two ends of dial framework by pin and screw, and described dial gauge is arranged on the centre position of dial framework by adjustment screw and opening sleeve.
This utility model has the advantages that owing to using said structure:
1, this utility model be applicant company be that the part in aero-engine carries out quality testing and custom-designed special measuring tool, this measuring tool overcomes testing staff in prior art by the big shortcoming and defect of visual error, there is accuracy of detection high, the advantages such as error is little, reproducible.
2, this utility model is simple and reasonable, meets its detection performance requirement that major diameter dimension parts batch being not easy to measure produces external diameter, low cost such that it is able to enterprise economic benefit.
Accompanying drawing explanation
Fig. 1 is high accuracy diameter measuring tool overall structure schematic diagram.
Fig. 2 is the partial sectional view of this utility model Fig. 1.
Reference: 1, support A, 2, support B, 3, dial framework, 4, dial gauge, 5, adjust screw, 6, opening sleeve, 7, pin, 8, screw, 9, measured workpiece.
Detailed description of the invention
Shown in accompanying drawing 1,2: this measuring tool includes support A 1, support B 2, dial framework 3, dial gauge 4, adjusts screw 5, opening sleeve 6, pin 7 and screw 8, described support A1 and support B2 is that "eight" shape shape tilts to be symmetricly set on the two ends of dial framework 3 by pin 7 and screw, and described dial gauge 4 is arranged on the centre position of dial framework 3 by adjustment screw 5 and opening sleeve 6.
Operation principle:
During measurement by support A1 and support B2 built on qualified products part, dial gauge 4 carried out zeroing arrange by adjusting screw 5, fixing tighten to adjust after screw 5 determines the interval of acceptance scope of indicator i.e. can be used for detecting part to be checked.
