Abstract
A kind of airtight laboratory holder of aluminium alloy cavity, bottom and side at part to be tested, it is respectively arranged with side seal and sealing bottom surface part, by the way of once the bottom surface of part and side individually being sealed, ensure sealing effectiveness, simple in construction and manufacturing cost and manufacturing time are shorter simultaneously, it is possible to carry out hermeticity experiment under part status.The present invention can pass through said structure, improves and manufactures efficiency, it is to avoid produces idle work, and reduces the labor intensity of workman.
Description
Technical field
The invention belongs to field of machining, for the airtight experimental check of aluminium alloy castings inner chamber.
Background technology
Part to be tested is aluminium alloy support parts, for cockpit internal operating system, is widely used in aviation boat
It field, due to assembling install need, inner cavity of component should ensure that airtight requirement, do not allow assembling after leak gas, existing to this type of zero
Part carries out bubble-tight test, is the most all to carry out air-tight test inspection in the assembled condition, due to the peace installation and dismantling of assembling
Unloading requirement height, this type of method implements operator and exists, and time is long, when finding after test that part is undesirable,
Change other parts after unloading, the most sternly extend the duration, so hermeticity experiment is carried out more under part status
Appropriate, but simultaneously because this External Shape irregular, size essence, form and position tolerance are many and it needs to airtight inspection position inner chamber
For non-close structure, it is desirable to carry out airtight test, need to close this, and by part and fixture simultaneously encroached water, inwardly
Chamber is inflated, and checks air-tightness, so existing fixture can not meet requirements above.
Summary of the invention
In order to solve above-mentioned technical problem, the invention provides a kind of airtight laboratory holder of aluminium alloy cavity, for
This type of part, in bottom and the side of part, is respectively arranged with side seal and sealing bottom surface part, by once to part
The mode that bottom surface and side individually seal, it is ensured that sealing effectiveness, simple in construction and manufacturing cost and manufacturing time are shorter simultaneously, energy
Enough under part status, carry out hermeticity experiment, solve fixture present in prior art and do not mate it cannot be guaranteed that part
Closed state, and carry out in mated condition testing and long in time limit, the technical problem that matching requirements are high that cause.
To achieve these goals, the technical solution used in the present invention is: a kind of airtight laboratory holder of aluminium alloy cavity, bag
Include and need tested parts, it is characterised in that:
Being provided with sealing bottom surface part at feature bottom to be tested, sealing bottom surface part is provided with base plate, is provided with at plate upper surface
The baffle plate of the right angle hook bent inwards, plate upper surface, baffle interior is provided with pad, and baffle bottom is connected to by lining
On base plate, and the bottom surface of base plate is provided with the nut matched with lining, by the height of nut energy controllable register；
In the through hole, side of part to be tested, side seal is installed, the most inverted female part of side seal,
Inner side bottom the side vertical edge of female part is provided with packing ring by alignment pin, interior bottom the opposite side vertical edge of female part
Side is provided with briquetting；Screw passes camber member, and one end connects briquetting, and the other end connects handle, and during turning handle, briquetting is permissible
Movement is had before screw orientation.
Described briquetting is relative with gasket position, and briquetting is provided with sealing ring on the opposite face of packing ring.
The pressure inlet being connected with outer conduit it is provided with on described base plate.
Having the beneficial effects that of the invention: the invention provides a kind of airtight laboratory holder of aluminium alloy cavity,
For this type of part, in bottom and the side of part, it is respectively arranged with side seal and sealing bottom surface part, by once to zero
The mode that the bottom surface of part and side individually seal, it is ensured that while sealing effectiveness, simple in construction, and manufacturing cost and manufacturing time
Shorter, it is possible under part status, to carry out hermeticity experiment, improve production and processing efficiency, reduce labor strength.
