Abstract
The utility model discloses a kind of aluminium casting leak-checking apparatus, belong to the technical field of leak-checking apparatus, solve conventional apparatus and to leak hunting poor accuracy, ineffective problem.The utility model comprises tank, be located at tank in for installing the pedestal of aluminium casting, described pedestal is connected with inflation mechanism, the gas outlet that can outwards inflate is offered in pedestal, pedestal is removably connected with the hollow spindle for fixing aluminium casting, the junction of described hollow spindle and pedestal keeps sealing state, its gas outlet is communicated with hollow spindle, is provided with downward top-pressure mechanism above pedestal.Compared with prior art, improve the speed of leaking hunting, decrease single aluminium casting and to leak hunting required time, improve the accuracy of leaking hunting.
Description
[technical field]
The utility model relates to the technical field of leak-checking apparatus, particularly a kind of aluminium casting leak-checking apparatus.
[background technology]
Aluminium casting, after production completes, just can come into operation after needing to leak hunting to it.When at present aluminium casting being leaked hunting, put it in tank, by filling water in the sink, in order to fixing aluminium casting arranges mounting base usually in tank, observe it and whether leak gas, however this mode due to the gap in aluminium casting minimum time, the gas being difficult to observe out its surface with naked eyes is satisfied, accuracy of leaking hunting is lower, and it need be waited naturally to go out bubble, and efficiency is lower.
[utility model content]
The purpose of this utility model solves the problems of the prior art exactly, proposes a kind of aluminium casting leak-checking apparatus, can promote the speed of leaking hunting, and reduces single aluminium casting and to leak hunting required time, improves the accuracy of leaking hunting.
For achieving the above object, the utility model proposes a kind of aluminium casting leak-checking apparatus, comprising tank, being located in tank for installing the pedestal of aluminium casting, described pedestal is connected with inflation mechanism, offer the gas outlet that can outwards inflate in pedestal, pedestal is removably connected with the hollow spindle for fixing aluminium casting, the junction of described hollow spindle and pedestal keeps sealing state, its gas outlet is communicated with hollow spindle, is provided with downward top-pressure mechanism above pedestal.By inflating in fixture, as the aluminium casting in fixture has gap, can improve bubble and produce speed, top-pressure mechanism compresses aluminium casting in hollow spindle downwards, prevents aluminium casting be bullied and deviate from fixture so that produce gap, affects accuracy of leaking hunting.
As preferably, described top-pressure mechanism comprises support and cylinder, and described support to be fixed in tank and to be positioned at the top of pedestal, and described cylinder is rack-mount, in cylinder piston rod be oriented straight down, the distance of piston rod top and hollow spindle is positioned at the stroke range of piston rod.Start cylinder control piston bar to extend downwards, thus compress aluminium casting in hollow spindle.
As preferably, institute's hollow spindle and pedestal are spirally connected fixing.Be fixed on pedestal after conveniently placing aluminium casting in hollow spindle.
As preferably, the junction of described pedestal and hollow spindle is fixed with O-ring seal.Make pedestal and hollow spindle keep being tightly connected, prevent gas leakage.
As preferably, described inflation mechanism comprises gas piping and air pump, and pedestal connects air pump through gas piping, and described gas piping is communicated with gas outlet.Air pump is inflated to the aluminium casting being positioned at fixture by gas piping and gas outlet.
As preferably, described gas outlet is positioned at the center of base top surface.Aluminium casting is inflated evenly.
The beneficial effects of the utility model: compared with prior art, improve the speed of leaking hunting, and decrease single aluminium casting and to leak hunting required time, improve the accuracy of leaking hunting.
Feature of the present utility model and advantage will be described in detail by reference to the accompanying drawings by embodiment.
[accompanying drawing explanation]
Fig. 1 is structural representation of the present utility model.
In figure: 1-tank, 2-pedestal, 3-gas outlet, 4-hollow spindle, 5-support, 6-cylinder, 7-piston rod, 8-O-ring seal, 9-gas piping, 10-air pump.
[embodiment]
Consult Fig. 1, the utility model comprising tank 1, being located in tank 1 for installing the pedestal 2 of aluminium casting, described pedestal 2 is connected with inflation mechanism, described inflation mechanism comprises gas piping 9 and air pump 10, pedestal 2 connects air pump 10 through gas piping 9, offer the gas outlet 3 that can outwards inflate in pedestal 2, described gas piping 9 is communicated with gas outlet 3.Pedestal 2 is removably connected with the hollow spindle 4 for fixing aluminium casting, described hollow spindle 4 can keep sealing state with the junction of pedestal 2, its gas outlet 3 is communicated with hollow spindle 4, is provided with the top-pressure mechanism compressing aluminium casting in hollow spindle 4 downwards above pedestal 2.Described top-pressure mechanism comprises support 5 and cylinder 6, described support 5 to be fixed in tank 1 and to be positioned at the top of pedestal 2, described cylinder 6 is arranged on support 5, in cylinder 6 piston rod 7 be oriented straight down, the distance of piston rod 7 top and hollow spindle 4 is positioned at the stroke range of piston rod 7.Institute's hollow spindle 4 and pedestal 2 are spirally connected fixing.Described pedestal 2 is fixed with O-ring seal 8 with the junction of hollow spindle 4.Described gas outlet 3 is positioned at the center of pedestal 2 end face.
Using method of the present utility model: first at tank 1 water-filling, in hollow spindle 4, aluminium casting to be detected is installed, then hollow spindle 4 is installed on pedestal 2, be spirally connected both making combination, pedestal 2 can keep both to seal with the O-ring seal 8 of the junction of hollow spindle 4, gas outlet 3 on pedestal 2 is close to the bottom surface of aluminium casting, starting cylinder 6 makes piston rod 7 extend until compress aluminium casting downwards, then booster air pump 10 is inflated to aluminium casting, whether have bubble produce, complete and leak hunting if observing its surface.
Above-described embodiment is to explanation of the present utility model, is not to restriction of the present utility model, anyly all belongs to protection domain of the present utility model to the scheme after the utility model simple transformation.
