Description

Air compressor machine air-following oil drain quantity testing tool
Technical field
The present invention relates to a kind of automobile air compressor testing tool, particularly relate to a kind of air compressor machine air-following oil drain quantity test work Tool.
Background technology
Air compressor machine alters/and leakage of oil is one of common fault of air compressor machine, and air compressor machine alters oil can affect the fortune of air compressor machine and vehicle Row work, even threatens traffic safety, therefore alters/the test of oil leakage fault and judge the most particularly important, mesh for air compressor machine Before conventional a kind of test and determination methods be to use special laboratory table, but this method needs to be transported to vehicle special Laboratory, it is impossible to use in service process after sale, and required high cost;Another kind of method is, uses filter paper filtering empty The lubricating oil in gas discharged by press, then weighs weight in the balance, contrasts with air compressor machine air-following oil drain quantity model and analyze, To the numerical value of the altering of air compressor machine/leakage of oil amount, but the most corresponding special testing tool, usually tester's hands on current market Holding filter paper, or the light instrument of hand-held interim making is tested, whole test process is loaded down with trivial details, and test result cannot be accurate Controlling, tester is also exposed in strong noise and tail gas environment, damages tester's health.
Summary of the invention
According to above the deficiencies in the prior art, the technical problem to be solved is: provide a kind of air compressor machine with gas Oil drain quantity testing tool, its simple in construction, it is simple to carry, easy to use, reliable test result.
The present invention is to be realized by following technical scheme: a kind of air compressor machine air-following oil drain quantity testing tool, including connecing Head, the rear cylindrical body of joint is fixed on inside the inner ring of bearing, and the outer ring of bearing is fixed on the inside of bearing holder (housing, cover), bearing holder (housing, cover) with Support, between seat, bracing frame is installed, by bearing, bearing holder (housing, cover), bracing frame, support seat and filter paper seat can be made to turn relative to joint Dynamic, bracing frame is tower structure, and gas can be discharged from space, it is to avoid air pressure is too high, supports seat rear portion and is provided with filter paper seat.
Be provided with breach on described bracing frame, actually used during, bracing frame may be with other zero on vehicle Part produces interferes, and offers the breach with interference portion respective numbers and shape, interference portion can be put into breach, so that surveying Trial work tool can be installed smoothly.
The rear portion external diameter of described bracing frame is more than anterior external diameter, owing to the parts at automobile engine position are many, structure Complexity, the most actually used in, the installing space of testing tool is narrow and small, and bracing frame front portion external diameter is little, enables testing tool suitable Profit is installed on air compressor machine, and rear portion external diameter becomes big, in order to install the filter paper being relatively large in diameter.
The screw thread matched with air compressor exhaust port is had, in the middle part of described joint on the anterior cylinder of described joint For hexagonal prism, by instruments such as spanners, it can be applied moment of torsion during installation, it is simple to testing tool is installed on air compressor machine, install Convenient, after installation, fastening is stable, is difficult to loosen.
The described inner ring supporting seat is stepped, and filter paper seat is the stepped boss of corresponding cooperation, supports and opens on seat Having draw-in groove, draw-in groove is L-shaped, and filter paper seat is provided with projection, and filter paper is placed between support seat and filter paper seat, and projection is snapped in card Groove is interior and rotation makes projection be deep into inside draw-in groove, is clamped in by filter paper and supports the stepped gap formed between seat and filter paper seat In.
Distance between rear end face and the front end face of filter paper seat of described joint is 5 centimetres, so that filter paper and joint Rear end face between distance meet testing standard requirement, improve the reliability of test result.
Pass through to weld or rivet to be fixed together between described bracing frame with bearing holder (housing, cover), support seat.
The rear cylindrical body of described joint is fixed together by the way of interference fit with the inner ring of bearing.
Described bearing holder (housing, cover) is fixed together by the way of interference fit with the outer ring of bearing.
The invention has the beneficial effects as follows:
A kind of air compressor machine air-following oil drain quantity testing tool provided by the present invention, has filled up the market vacancy, has changed tradition Handheld test and the simple and crude present situation of testing tool, present configuration is simple, it is simple to carry, easy to use, reliable test result.
During use, instrument is installed on air compressor machine, to be tested after take off, then by filter paper and model relative analysis Test result can be drawn, in test process, it is no longer necessary to tester participates in, make tester be no longer influenced by noise and tail gas Impact.
During actually used, testing tool may produce with other parts on vehicle interferes, the support of the present invention It is provided with breach on frame, offers the breach with interference portion respective numbers and shape, interference portion can be put into breach, now Bracing frame can not be rotated about axis, and by bearing, makes joint can not still be able in the case of rotating be rotated about axis at bracing frame, It is thus possible to joint is screwed in air compressor exhaust port, so that whole testing tool can be installed smoothly.
Owing to the parts at automobile engine position are many, structure is complicated, the most actually used in, the installation of testing tool is empty Between narrow and small, and filter paper diameter used is the biggest, and the rear portion external diameter of the bracing frame of the present invention is more than anterior external diameter, before bracing frame Portion's external diameter is little, it is possible to put into narrow space, enables testing tool to be installed to smoothly on air compressor machine, and rear portion external diameter becomes big, To install the filter paper being relatively large in diameter.
By being threaded on joint and hexagonal prism, making the simpler convenience of installation process, after installation, fastening is stable, It is difficult to loosen.
Coordinated by draw-in groove and raised structures, filter paper is clamped in and supports the stepped gap formed between seat and filter paper seat In, it is to avoid during use, filter paper loosens or drops.
It is remote the nearest that the mode of conventional hand-held filter paper test causes the distance between filter paper and air vent to be neglected, impact test knot Really, the testing standard of 5 centimetres is remained between rear end face and the front end face of filter paper seat of the present invention in use joint Distance, improves the reliability of test result.
