Effect is bad in examination, inefficiency and the problem that cannot detect the qualified degree of oil pipe spatial form.
The technical scheme is that and be achieved in that: a kind of airtight test machine, including water tank, described water tank
Being arranged over elevating mechanism, described elevating mechanism lower end connects test framework, is provided with in described test framework
Primary seal is blocked up and from closure, and described primary seal is stifled and described accompanies test oil pipe between closure, and described primary seal is stifled logical
Crossing cylinder arm to be driven by clamping cylinder, be provided with gas tube in described cylinder arm, the outlet of described gas tube is located at
In described primary seal is stifled, the stifled and described tendency between closure along described test oil pipe of described primary seal is provided with at least
One simulation engine mounting support, described simulation engine mounting support is arranged with the plane perpendicular of described test framework, described
Simulation engine mounting support is provided with support slot, and the pipe shaft of described test oil pipe is shelved in described support slot.
As one preferred embodiment, the described junction from closure with described test framework is provided with universal joint.
As one preferred embodiment, described primary seal blocks and is equipped with a caulking gum with described from closure
Pad.
As one preferred embodiment, the bottom surface of described test framework is provided with several permeable holes.
As one preferred embodiment, described water tank is arranged over crossbeam, and described elevating mechanism is arranged on institute
State on crossbeam.
As one preferred embodiment, an intake-outlet it is provided with below described water tank.
As one preferred embodiment, described elevating mechanism, described clamping cylinder, described gas tube by
One integrated manipulator is controlled.
After have employed technique scheme, the invention has the beneficial effects as follows: according to existing rustless steel engine oil adding pipe
Shape of product size, design specialized frock carries out air-tight test to it, and in frock, primary seal is stifled realizes clamping
And inflation, flexibly connecting with main body employing from closure, adaptability adjusts gripping angle, convenient location automatically
Test oil pipe, and it is applicable to similar structures but the N kind product of different angles, according to pipe shape and tendency
Simulation engine mounting support is set, forms the mould of detection pipe fitting, after pipe fitting is produced in batches, as long as can be successful
It is placed in the simulation engine mounting support of specific node location, i.e. can determine that this pipe fitting spatial shape is qualified.This gas
Close testing machine structure is compact, reasonable in design, Workpiece clamping, enters water, automatic inflating, pressurize, water outlet, work
Part unclamps each action and all uses operating in a key, easy to operate, and is effectively increased the three-dimensional pipe fitting of inspection and is
No qualified work efficiency, has saved manpower and materials, promotes the lifting of productivity effect.
