Abstract
The utility model discloses a plug for engine water pump hole leakage tests and relates to the technical field of automobile part manufacturing. The plug comprises a handle, a pin shaft, a sliding block, a sealing block and a pull rod, wherein the handle is connected with the pull rod and is provided with the pin shaft in a penetrating mode, the sliding block is arranged outside the pull rod, the sealing block is arranged between the sliding block and the bottom end of the pull rod, and a gasket is arranged at the end, close to the pin shaft, of the sliding block. The plug is simple in structure, convenient to operate, uniform in sealing, good in sealing performance, long in service life, wide in application range and applicable to sealing of holes with various diameters, and the air leakage phenomenon caused by overlarge air pressure can be avoided due to the arrangement of a self-locking device.
Description
Technical field
The utility model relates to Manufacturing Technology for Automotive Parts field, is specifically related to a kind of engine water pump hole seal tightness test plug.
Background technique
The production of automobile engine water pump, oil pump, all must 100% before dispatching from the factory do air tightness test, institute is porose all must stop up, with 500kpa air pressure, test, particularity due to engine shell body structure, it is normal in prior art that what adopt is taper plug, with cylindrical plug and the end face seal plug of O type circle, but in this plug of form existing problems as following table:
| seal form | existing problems |
| cone seal plug | easy to wear, service time is short, and inconvenience is installed, and sealing effect is bad. |
| seal plug with "O"-ring | elasticity is low, and sealing effect is bad, and O type circle is easily damaged by aperture burr plucking, and working life is low. |
| end face seal plug | aperture end face planarization is had relatively high expectations, during use, have narrow limitation, poor sealing. |
Summary of the invention
The purpose of this utility model is to provide a kind of engine water pump hole seal tightness test plug, it is simple in structure, easy to operate, sealing is even, good seal performance, long service life, with self-locking device, in the time of can avoiding air pressure excessive, produce gas leak phenomenon, using scope is wide, can adapt to the sealing in various apertures.
In order to solve the existing problem of background technique, the utility model is by the following technical solutions: it comprises handle, bearing pin, slide block, sealing block, pull bar, described handle is connected with pull bar, on handle, be installed with bearing pin, pull bar is outside equipped with slide block, between slide block and pull bar bottom, be provided with sealing block, slide block is provided with pad near place, bearing pin one end.
It is simple in structure, easy to operate for the utility model, sealing evenly, good seal performance, long service life, with self-locking device, produces gas leak phenomenon in the time of can avoiding air pressure excessive, using scope is wide, can adapt to the sealing in various apertures.
Accompanying drawing explanation:
Fig. 1 is the utility model structural representation.
Embodiment:
Referring to Fig. 1, this embodiment is by the following technical solutions: it comprises handle 1, bearing pin 2, slide block 3, sealing block 4, pull bar 5, described handle 1 is connected with pull bar 5, on handle 1, be installed with bearing pin 2, pull bar 5 is outside equipped with sliding 3, between slide block 3 and pull bar 5 bottoms, be provided with sealing block 4, slide block 3 is provided with pad 6 near place, bearing pin one end.When the utility model is used, first pull bar bottom and sealing block are inserted in hole to be sealed, then operating grip rotates around bearing pin, slide block and pull bar will be to intermediary movementses like this, sealing block produces distortion under the extruding of pull bar and slide block, and when handle rotates 90 °, sealing block produces distortion maximum and tightly fits with the hole inwall of required sealing, thereby reach complete sealing state, handle is also in self-locking state simultaneously.
