Description
Technical field
The utility model is related to a kind of air-tightness detection device, belongs to air-leakage test technical field.
Background technology
In the prior art, generally it is required for carrying out air-leakage test to the part for having air-tightness requirement, to determine if
Gas leakage, leakage etc., and then determine if qualified, make every effort in advance detect the undesirable parts of air-tightness, keep away
Exempt from it to install or use the quality and overall performance for reducing product on product.
As shown in figure 1, structure of the air intake assembly in certain Work piece sealing space for both ends open, the processing of its air inlet is described
On the madial wall of component, when air-leakage test is carried out to the Work piece sealing space, because the location comparison of air inlet is hidden,
It is difficult to pass through conventional valve it is inflated, so as to the air-leakage test for leading the Work piece sealing space is more difficult.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of air-tightness detection device, the air-leakage test dress
Put simple and reasonable, the problem that can effectively overcome the Work piece sealing inflated spatial difficult.
The purpose of this utility model is realized by following technical scheme：
A kind of air-tightness detection device, described device mainly includes cylinder, inlet suction port and rubber parts；
Wherein, the gas outlet of the inlet suction port is located at the middle part of push rod, and between the gas outlet and push rod end face
Outer circumference surface on be machined with seal boss, it is convex to be machined with clamping on the outer circumference surface between the gas outlet and air inlet
Platform；And the size phase of the distance between the seal boss and the clamping boss with the air intake assembly of workpiece for measurement sealing space
Adapt to；
The rubber parts is the cylinder-like structure of both ends open, and its upper-end inner diameter is less than the external diameter of the clamping boss, under
Annular boss is machined with the outer circumference surface at end, the inner surface at middle part is machined with the groove cooperated with the seal boss；
The cylinder is connected with the air inlet of the inlet suction port；The rubber parts is sleeved on the push rod of the inlet suction port
On, and the rubber parts is slidably matched with the push rod, and by the clamping boss and the seal boss to the rubber
Part carries out spacing.
Further, described device also includes the workpiece locating rack for fixing and positioning workpiece for measurement sealing space.
Further, the lower surface of the seal boss is provided with O-ring.
Beneficial effect
(1) air-tightness detection device described in the utility model is simple and reasonable, effectively overcomes workpiece for measurement sealing
The air inlet in space is hidden, it is impossible to carry out the defect of air-leakage test, is the workpiece for measurement sealing space quality and entirety that improve
Performance provides guarantee well.
(2) air-tightness detection device described in the utility model is determined Work piece sealing space to be measured by workpiece locating rack
Position and fixation, have effectively ensured the convenience and feasibility of air-leakage test.
(3) air-tightness detection device described in the utility model is cooperated by seal boss and O-ring, can be effectively improved
The sealing of the air intake assembly, so as to ensure the reliability of air-leakage test.

Specific embodiment
The utility model, but not limited to this are described in detail in detail with specific embodiment below in conjunction with the accompanying drawings.
Embodiment 1
As shown in figure 1, a kind of air-tightness detection device, described device is mainly including cylinder 1, inlet suction port 2 and rubber parts
3；
Wherein, the gas outlet of the inlet suction port 2 is located at the middle part of push rod, and between the gas outlet and push rod end face
Outer circumference surface on be machined with seal boss, it is convex to be machined with clamping on the outer circumference surface between the gas outlet and air inlet
Platform；And the size of the distance between the seal boss and the clamping boss with the air intake assembly 6 of workpiece for measurement sealing space 7
It is adapted；
The rubber parts 3 is the cylinder-like structure of both ends open, and its upper-end inner diameter is less than the external diameter of the clamping boss, under
Annular boss is machined with the outer circumference surface at end, the inner surface at middle part is machined with the groove cooperated with the seal boss；
The cylinder 1 is connected with the air inlet of the inlet suction port 2；The rubber parts 3 is sleeved on the inlet suction port 2
On push rod, and the rubber parts 3 is slidably matched with the push rod, and by the clamping boss and the seal boss to described
Rubber parts 3 carries out spacing.
Described device also includes the workpiece locating rack 5 for fixing and positioning workpiece for measurement sealing space 7.
The lower surface of the seal boss is provided with O-ring 4.
Operation principle：
As shown in figures 2-3, the end of the push rod of the inlet suction port 2 is slid into the rubber parts 3, by described
Seal boss and the groove cooperate and carry out spacing, prevent rubber parts 3 from skidding off the push rod；By workpiece for measurement sealing space
7 are arranged on the workpiece locating rack 5, are upper end and the rubber parts 3 of the air intake assembly 6 of workpiece for measurement sealing space 7
Lower end contradicts, and by sliding the push rod, the push rod is extend into the air intake assembly 6 until the seal boss and O
Type circle 4 is cooperated, and the lower end closed of the air intake assembly 6 now, is corrected and the clamping on the rubber parts 3
Boss is contradicted, and realizes the sealing to the upper end of the air intake assembly 6；Because the gas outlet of the inlet suction port 2 is located at the sealing
Between boss and clamping boss, therefore the gas in cylinder 1 directly can be filled with by air intake assembly 6, Ran Houqi by inlet suction port 2
Body enters the workpiece for measurement sealing space 7 by the air inlet of the madial wall of air intake assembly 6, completes inflation.
The utility model includes but is not limited to above example, every to be carried out under the principle of the utility model spirit
Any equivalent or local improvement, all will be regarded as within protection domain of the present utility model.
