Background technology
Development along with technology; The demand of lightweight bicycle and requirement are also increasingly high; Magnesium alloy front fork foundry goods is widely applied on the high-end bicycle, because its hydraulic shock-absorption functional requirement requires magnesium alloy front fork foundry goods must possess characteristic non-leakage under certain pressure.
In the existing gas leakage test process, employing be the mode that the dry type of differential pressure type is leaked hunting is leaked hunting, lean on equipment pressure monitoring function to judge whether leaking gas of foundry goods when leaking hunting.But weak point is exactly: 1, when the gas return path of leak-checking apparatus gas leakage takes place or because poorly sealed when causing leaking gas, equipment can not made early warning, all can be decided to be foundry goods gas leakage by erroneous judgement; 2, even foundry goods itself leaks gas, also be not easy to judge the position of gas leakage, make troubles for analyzing to improve.
Summary of the invention
In order to overcome above-mentioned defective; The invention provides a kind of soaking type gas leakage proving installation of bicycle front fork class foundry goods; Can solve the labile factor in the production; Judge more accurately whether the front fork foundry goods leaks gas, and judge the concrete gas leakage position of foundry goods simultaneously, for the statistical study of doing bad phenomenon provides foundation.
The present invention for the technical scheme that solves its technical matters and adopt is: a kind of soaking type gas leakage proving installation of bicycle front fork class foundry goods; Comprise base and the framework that is fixed in the base top; The centre position is provided with some locating pieces that are used for fixing foundry goods to be tested on the said base; Said framework is fixed with a pressure holding cylinder over against the below, position of locating piece, and the below of pressure holding cylinder drives connection one and is used for the pressure holding piece that vertical direction pushes against foundry goods to be tested; Be fixed with the seal stack cylinder on the framework of said base one side, said each sealing cylinder drives the adapter that connection one is used for laterally promoting foundry goods to be tested towards the locating piece direction; Corresponding sealing cylinder is fixed with the seal stack cushion block on the framework of said base opposite side; Said each seal block is provided with a vent line; Vent line is communicated with air intake opening on the framework, and said air intake opening, vent line, locating piece upper surface and adapter are on the same surface level.
As further improvement of the present invention, said adapter is provided with the movable sealing piece that cooperates with foundry goods to be tested, and the junction of said seal block and foundry goods to be tested is provided with O-ring seal.
As further improvement of the present invention, said movable sealing piece is processed by the abrasive rubber material, and the movable sealing piece is provided with to connect and use screw thread, is convenient to replacing.
As further improvement of the present invention, said base is provided with three locating pieces, and concrete gas leakage position is more conveniently found out in the even interval of each locating piece.
As further improvement of the present invention, the diameter of said vent line is 5mm.
The invention has the beneficial effects as follows:
1. aspect relative locations of structures relation: leak-checking apparatus of the present invention is a framed structure, and its lower shoe and body side frame are used for fixing locating device and auxiliary sealing device, and the top of framework is used for fixing clamping cylinder; And link to each other with the external drive cylinder through syndeton; Realizing moving up and down of a whole set of anchor clamps, and then realize the action of immersion and water outlet, in addition; The locating piece device changes three stage structure into, the gas leakage situation of more convenient observation foundry goods.
2. aspect judgement gas leakage mode: leak-checking apparatus of the present invention mainly acts on and is foundry goods clamping to be tested is had good positioning; And through the outside electric control gear realization inflation pressurization function inner to the product die cavity; After being pressurized to the pressure of appointment; Whether the external control device has the mode that bubble is emerged to judge whether leak gas through observing in the water its whole immersion in the water, can determine the position of gas leakage and the order of severity of gas leakage intuitively.

Embodiment
In order to deepen to understanding of the present invention, will combine embodiment and accompanying drawing that the present invention is made further detailed description below, this embodiment only is used to explain the present invention, does not constitute the qualification to protection domain of the present invention.
Fig. 1-2 has shown a kind of embodiment of the soaking type gas leakage proving installation of a kind of bicycle front fork class of the present invention foundry goods; Comprise base 1 and the framework 2 that is fixed in base 1 top; The centre position is provided with some locating pieces 3 that are used for fixing foundry goods to be tested on the said base 1; Said framework 2 is fixed with a pressure holding cylinder 4 over against the below, position of locating piece 3, and the below of pressure holding cylinder 4 drives connection one and is used for the pressure holding piece 5 that vertical direction pushes against foundry goods to be tested; Be fixed with seal stack cylinder 6 on the framework 2 of said base 1 one sides, said each sealing cylinder 6 drives the adapter 7 that connection one is used for laterally promoting foundry goods to be tested towards locating piece 3 directions; Corresponding sealing cylinder 6 is fixed with seal stack cushion block 8 on the framework 2 of said base 1 opposite side; Said each seal block 8 is provided with a vent line 9; Vent line 9 is communicated with air intake opening 10 on the framework, and said air intake opening 10, vent line 9, locating piece 3 upper surfaces and adapter 7 are on the same surface level, and said adapter 7 is provided with the movable sealing piece 11 that cooperates with foundry goods to be tested; Said seal block 8 is provided with O-ring seal 12 with the junction of foundry goods to be tested; Said movable sealing piece 11 is processed by the abrasive rubber material, and movable sealing piece 11 is provided with to connect and uses screw thread, and said base 1 is provided with three locating pieces 3; Each locating piece 3 is the interval evenly, and the diameter of said vent line 9 is 5mm.
