Abstract
The utility model relates to an automatic air charging device for detecting air impermeability of an automotive transmission assembly, belonging to the technical field of the detection of the air impermeability of the automotive transmission assembly. The automatic air charging device has the technical scheme that the automatic air charging device comprises an air pipe joint (1), a ventilating pin (8), a hole plug (10) and a spring (7), wherein two ends of the hole plug are respectively provided with a hole section with a larger diameter, the two hole sections are communicated with each other by a hole section with a smaller diameter, the air pipe joint is filled into the hole section at one end of the hole plug, one end, which is filled into the hole section, of the air pipe joint, is connected with the ventilating pin through the spring, and the ventilating pin slides within the hole section with a smaller diameter between the two hole sections. After the automatic air charging device is adopted, according to the ventilating pin and the spring in the hole plug, the automatic air charging and the automatic air charge stopping are realized, so that the operation process is simplified, i.e. the process that an air source needs to be manually turned off after examination can be simplified; according to a pothook and a support, an input plug can not be pulled away under the action of compressed air; and tooling does not need to be assembled and disassembled, so that the labor efficiency can be improved, and the labor intensity can be reduced.
Description
Technical field
The utility model relates to a kind of automotive transmission assembly impermeability and detects self-filler, belongs to automotive transmission impermeability detection technique field.
Background technology
Can whether impermeability detects, be to detect each point of attachment of automotive transmission assembly to have the gas leakage problem to take place, normally bring into play function in car load to variator and play decisive role.At present, generally the air-tightness detection method of Shi Yonging is that transmission assembly is immersed in the water, injects the air of certain pressure, checks whether each point of attachment has bubble to produce.The problem that background technology exists is: with the sealing of pressure gas detection assembly, to the transmission assembly injecting compressed air time, because of pressurized air produces pressure, throw off easily under pressure; Also need artificial fastening frock, otherwise can't guarantee the stability of variator internal pressure; In addition, the installing/dismounting frock is consuming time, inefficiency.
The utility model content
The utility model purpose provides a kind of automotive transmission assembly impermeability and detects self-filler, does not need the installing/dismounting frock, has improved efficiency, has reduced labour intensity, solves the problems referred to above that background technology exists.
The technical solution of the utility model is: automotive transmission assembly impermeability detects self-filler, comprise blast connection, ventilation pin, the hole is stifled and spring, stifled two ends, hole are respectively equipped with the bigger hole section of diameter, be communicated with by the less hole section of diameter between two hole sections, blast connection is filled in the hole section of the stifled end in hole, the end that blast connection is filled in the hole section is connected with the ventilation pin by spring, and ventilation is sold in the less hole section of between two hole sections diameter and slided.
The end that described ventilation pin is connected with spring is provided with nut or boss, and the external diameter of nut or boss is greater than the internal diameter of ventilation pin institute sliding eye section.
Also be provided with support on described hole is stifled, support is provided with hook, is provided with hook spring between hook and the support.
Described support blocks up in the hole by screw retention, and support is connected by bearing pin with hook, and hook spring is connected the hole by spring screw and blocks up.
Good effect of the present utility model: adopt the utility model, ventilation pin, spring in blocking up by the hole are realized inflation automatically, stop air feed automatically, have simplified operating process, have promptly simplified the process that need manually close source of the gas of having examined; Crossing hook, support has avoided input to get lodged under the pressurized air effect; Do not need the installing/dismounting frock, improved efficiency, reduced labour intensity.
Description of drawings
Fig. 1 is the ventilate structural representation of pin closed condition of the utility model embodiment;
Fig. 2 is the ventilate structural representation of pin open mode of the utility model embodiment; ,
Among the figure: blast connection 1, screw 2, bearing pin 3, support 4, hook spring 5, spring screw 6, spring 7, ventilation pin 8, hook 9, hole stifled 10.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further by embodiment.
Automotive transmission assembly impermeability detects self-filler, comprise blast connection 1, ventilation pin 8, hole stifled 10 and spring 7, stifled two ends, hole are respectively equipped with the bigger hole section of diameter, be communicated with by the less hole section of diameter between two hole sections, blast connection is filled in the hole section of the stifled end in hole, the end that blast connection is filled in the hole section is connected with the ventilation pin by spring, and ventilation is sold in the less hole section of between two hole sections diameter and slided.The end that described ventilation pin is connected with spring is provided with nut or boss, and the external diameter of nut or boss is greater than the internal diameter of ventilation pin institute sliding eye section.
Also be provided with support 4 on described hole is stifled, support is provided with hook 9, is provided with hook spring 5 between hook and the support.Described support is fixed on the hole by screw 2 and blocks up, and support is connected by bearing pin 3 with hook, and hook spring is connected the hole by spring screw 6 and blocks up.
The course of work of the present utility model: when impermeability detects, hole plug is gone into the variator output terminal, ventilation pin pushes up to be moved to the left on the output shaft and opens valve pressure-air is charged in the transmission assembly simultaneously, hangs over simultaneously on the transmission assembly, and the variator impermeability detects and begins; It is stifled to extract the hole after airtight detection finishes, and the ventilation pin moves right under the effect of pressurized air and spring and closes valve simultaneously, and the transmission assembly impermeability detects and finishes, and waits for that the transmission assembly impermeability detects next time.
