Abstract
The utility model discloses a sealing property testing device. The testing device comprises a large end cap, the large end cap is a cruciform shaft, a sealing groove is circumferentially arranged outside the shaft, a sealing ring is arranged in the sealing groove, the large end cap is placed at the lower end of a cavity in the workpiece to be tested, an air pipe joint is arranged at the side part of the workpiece to be tested, after air is introduced, the air pipe joint is communicated with the inside of the workpiece to be tested, a shaft head at one end of the end cap is provided with a rubber pad, the rubber pad abuts against the upper end of the cavity in the workpiece to be tested, an enclosed space is formed in the workpiece to be tested, and the sealing property of the workpiece is tested by introducing air through the air pipe joint. Compared with the prior art, the sealing property testing device of the utility model has the advantages that: the enclosed space is formed in the product by the large end cap, the overall product is submerged in water and the air is introduced so as to conduct a test, and misjudgment phenomena due to interference of external factors are avoided; and at the same time, the tooling has simple structure, convenient operation, and good test effect.
Description
Technical field
The utility model belongs to the tooling device technical field, relates in particular to a kind of Leakage Test frock.
Background technology
In the process of processing cylinder cap, the sealing of inspection cylinder cap is one of indispensable operation, and the product hermeticity difference quality that processes can influence the assembling with other parts.Method in the past is to utilize special-purpose squeezer, in cylinder cap, pours water, and then pipeline is adjusted to required pressure; Check that appearance sees if there is the seepage phenomenon, this method is troublesome poeration not only, and check is wasted time and energy; And be easy to generate spray and splash; The place is moist, has reduced the efficient of Leakage Test, has influenced the qualification rate of product.
Summary of the invention
The utility model technical matters to be solved is the present situation to prior art, provides a kind of simple in structure, easy to operate, the Leakage Test frock that test effect is good.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of Leakage Test frock, comprise big plug, and described big plug is the cross oblique crank Z; The axle excircle is to sealed groove is set; In the described groove O-ring seal is set, big plug is placed in the lower end of workpiece cavity to be checked, the sidepiece of workpiece to be checked is provided with gas-tpe fitting; Gas-tpe fitting ventilation back communicates with the inside of workpiece to be checked; On big plug one end rubber blanket is set, upward supports the lower end of workpiece cavity to be checked, make workpiece formation confined space to be checked and check sealing through the gas-tpe fitting ventilation.
In above-mentioned a kind of Leakage Test frock, described O-ring seal is an O-ring seals.
In above-mentioned a kind of Leakage Test frock, the upper end arranged outside nylon cushion of workpiece to be checked.Here increase sealing property through the nylon cushion pad, guaranteed qualified rate.
In above-mentioned a kind of Leakage Test frock, this Leakage Test frock integral body is flooded in the entry inspection and is had or not bubble, to judge whether product hermeticity is qualified.
Compared with prior art; The advantage of the utility model is that making workpiece formation confined space to be checked and integral body flood to ventilate in the entry through big plug tests, avoided other extraneous factor to disturb and cause the erroneous judgement phenomenon, and whole tool structure is simple simultaneously; Easy to operate, test effect is good.
Description of drawings
Fig. 1 is the one-piece construction synoptic diagram of this Leakage Test frock.
Reference numeral: big plug 1, O-ring seal 2, gas-tpe fitting 3, rubber blanket 4, nylon cushion 5, workpiece to be checked 6.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the technical scheme of the utility model is done further to describe, but the utility model is not limited to these embodiment.
As shown in Figure 1, this Leakage Test frock mainly is the sealing that is used for checking workpiece 6 to be checked, and the frock of the utility model comprises big plug 1; Described big plug 1 is the cross oblique crank Z; The axle excircle is provided with O-ring seal 2 to sealed groove is set in the described sealed groove, described O-ring seal 2 is an O-ring seals; Big plug 1 is placed in the lower end of workpiece 6 cavitys to be checked; The sidepiece of workpiece 6 to be checked is provided with gas-tpe fitting 3, and gas-tpe fitting 3 ventilation backs communicate with the inside of workpiece 6 to be checked, on big plug 1 one ends rubber blanket 4 are set; Go up the lower end of supporting workpiece 6 cavitys to be checked, make workpiece 6 formation confined spaces to be checked and after gas-tpe fitting 3 ventilations, can carry out air tight test.In order to increase qualified rate, the upper end arranged outside nylon cushion 5 of workpiece 6 to be checked.
During examining workpieces, this Leakage Test frock integral body is flooded in the entry, through gas-tpe fitting 3 ventilations, inspection has or not bubble, judges whether the sealing of workpiece 6 to be checked is qualified then, stops after the check ventilating and with this frock and separated form water, taking out workpiece 6 to be checked and get final product.
Specific embodiment described herein only is that the utility model is illustrated.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from the defined scope of the utility model.
