Abstract
The utility model discloses a measuring device matching with a pneumatic measuring instrument, composed of a measuring probe and a master. The working surface and the positioning surface of the measuring probe and the master are respectively coat-plated with a layer of titanium nitride, which improves the durability and prolongs the service life more than five times; with a high economic benefit, the utility model can be widely used on the pneumatic measuring instrument.
Description
Technical field
The utility model relates to a kind of and the matching used measurement mechanism of air-gauge.
Background technology
Known and the matching used measurement mechanism of air-gauge because the working surface anti-wear performance of its measuring head and check gauge is poor, cause precision stability bad, and serviceable life is short.
Summary of the invention
The purpose of this utility model be to provide the working surface anti-wear performance of a kind of measuring head and check gauge high with the matching used measurement mechanism of air-gauge, it has prolonged the serviceable life of measuring head and check gauge effectively.
The purpose of this utility model is achieved in that the measuring head main body outside surface at the measurement of air-gauge dress is that the inside surface of working surface and check gauge matrix is working surface coating one deck titanium nitride, and it can prolong the serviceable life of measuring head and check gauge effectively.
The utility model is because at the measuring head body of work surface of the measurement mechanism of air-gauge and working surface coating one deck titanium nitride of check gauge matrix, and the anti-wear performance height of titanium nitride, so improved the wearing quality of measuring head and check gauge, the retentivity of dimensional accuracy greatly, caused the measuring head that does not have the titanium nitride coated layer serviceable life of measuring head and check gauge and check gauge to improve more than five times.
Describe the utility model in detail below in conjunction with drawings and Examples.
Description of drawings
Fig. 1 is a front view of the present utility model;
Fig. 2 is the A-A cut-open view of Fig. 1;
Fig. 3 is the front view of the check gauge of measurement mechanism;
Fig. 4 is the cut-open view of the check gauge of measurement mechanism.
Specific embodiments
This device comprises respectively one of a measuring head and upper and lower limit check gauge.Measuring head is made up of measuring head main body 2, pipe adapter 3 and handle 4.The working surface coating of measuring head main body 2 one deck titanium nitride 1, the working surface coating of check gauge one deck titanium nitride 6.Pipe adapter 3 is packed in the measuring head body 2, and handle 4 usefulness screw threads are connected with measuring head main body 2, form a measuring head.
During use, at first the lower limit check gauge is inserted on the measuring head, make the nozzle of measuring head be positioned at the centre of check gauge width, open the gas admittance valve of air-gauge, regulated quantity instrument zero-bit is taken off the lower limit check gauge, put upper limit check gauge, rotation air-gauge enlargement factor knob carries out the multiple adjustment, regulates enlargement factor and zero-bit with the bound check gauge repeatedly, reaches till the requirement.During measurement, measuring head 2 is connected with air-gauge, and measuring head 2 is inserted in the measured hole, and by the pressure gas that air-gauge comes, the relative nozzle in two positions that enters measuring head through pipe adapter 3 sprays, with the internal diameter of measured hole.
Claims (1)
1, a kind of measurement mechanism of air-gauge, it comprises measuring head and the check gauge of being made up of measuring head main body (2), pipe adapter (3), handle (4), it is characterized in that:
A, be working surface coating one deck titanium nitride (1) at the outside surface of measuring head main body (2);
