Abstract
The utility model relates to a manual air-tightness tester of a cylinder cover. One end of a U-shaped support is fixedly connected with a nut, and a bolt locking rod is arranged in the nut; a sealing rubber mat is arranged on the top end of the bolt locking rod; the other end of the U-shaped support is fixedly connected with a nut, and a bolt locking connecting rod is arranged in the nut; one end of the bolt locking connecting rod is connected with an air pipe with a pressure gauge, and the other end thereof is connected with a cylindrical sealed cavity; the sealing rubber mat is arranged in the cylindrical sealed cavity; and an O-shaped sealing ring is arranged at the end part of the cylindrical sealed cavity. The manual air-tightness tester of the cylinder cover has compact structure and reasonable design, adopts the single-hole suppressing method, thus avoiding hidden danger of quality of a camshaft caused by the disassembly of a bearing cap, further leading to smooth repair, improving the repair rate, providing a suppressing tool for the development of new products, guaranteeing the smooth development of new products, and saving cost for the development of new products.
Description
Technical field
The utility model relates to the bubble-tight testing tool of a kind of automobile engine cylinder head, is specifically related to a kind of instrument that is used for cylinder cover outer wall gas pressure test.
Background technology
At present, cylinder cover of automobile engine outer wall gas pressure test is used to guarantee cylinder cap outer wall impermeability, thereby chamber pressure is stable when guaranteeing cylinder cap work, and the distribution abundance is guaranteed the The combustion chamber sufficient combustion, engine capacity is reliable, thereby avoids unacceptable product to flow out, and influences engine performance.At present, the cylinder cap air-tight test is mostly by suppressing special plane or suppressing transfer matic and finish, cylinder cap is by artificial clamping or raceway transmission, lathe clamps automatically, anchor clamps are obturaged top, bottom surface and each guide hole simultaneously, and the cylinder cap inner chamber forms the space of obturaging, and inject air by draft tube to the inner chamber of obturaging, detector is judged the air pressure leakage rate automatically, confirms whether the cylinder cap impermeability is qualified.But, problems such as valve guide bushing fracture appear when the cylinder cap finished product, and in the time of need reprocessing,, therefore can't obturage and suppress with stamper owing to can not remove bearing cap in order to avoid influence the camshaft hole size.Simultaneously, when development cylinder cap new product, because the variation of cylinder cap structure, the stamper anchor clamps can not be realized obturaging.
Summary of the invention
The purpose of this utility model is to overcome the weak point that exists in the above-mentioned technology, and a kind of compact conformation, reasonable in design is provided, and single hole is suppressed the manual testing tool of cylinder cap impermeability of having avoided the camshaft hidden danger of quality that brings because of the dismounting bearing cap.
In order to achieve the above object, the technical solution adopted in the utility model is: an end and the nut of U type support are affixed, the bolt check lock lever is installed among the nut, the top of bolt check lock lever is equipped with the rubber cushion of obturaging, the other end and the nut of U type support are affixed, bolt locking connecting link is installed among the nut, one end of bolt locking connecting link is connected with being with manometric airduct, the other end connects the cylindrical chamber of obturaging, the rubber cushion of obturaging is installed in the inside in the cylindrical chamber of obturaging, and the O type is obturaged and enclosed the end that is installed in the cylindrical chamber of obturaging.
The utility model has the advantages that:
The utility model compact conformation, reasonable in design, single hole is suppressed and has been avoided the camshaft hidden danger of quality that brings because of the dismounting bearing cap, make and reprocess and to carry out smoothly, and improved and reprocessed efficient, for the new product development provides the instrument of suppressing, the development of assurance new product is carried out smoothly, for cost has been saved in the new product development.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the wiring layout of suppressing of the present utility model;
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
By Fig. 1-Fig. 2 as can be known, one end and the nut 2 of the utility model U type support 1 are affixed, bolt check lock lever 3 is installed among the nut 2, the top of bolt check lock lever 3 is equipped with the rubber cushion 4 of obturaging, the other end and the nut 5 of U type support 1 are affixed, bolt locking connecting link 6 is installed among the nut 5, one end of bolt locking connecting link 6 is connected with being with manometric airduct, the other end connects the cylindrical chamber 7 of obturaging, the rubber cushion 8 of obturaging is installed in the inside in the cylindrical chamber 7 of obturaging, the O type end that circle 9 is installed in the cylindrical chamber 7 of obturaging of obturaging.
The utility model is when testing single guide hole outer wall impermeability, by regulating bolt check lock lever 3 and bolt locking connecting link 6, the guide hole of obturaging, form cavity simultaneously, then, by in cavity, squeezing into the pressure that needs, will suppress part afterwards and sink in the clear water with manometric airduct, by observing in the water whether bubble is arranged, thus the impermeability of detected catheter hole outer wall.
