Around cylinder constitute supporting table, bearing locating slot groove bottom on the outside of annular groove constitutes annular table；In supporting table and annular table
It is respectively provided with O-ring seal.Water-sealed bearing to be tested is enclosed in the test fluid in test groove, judges tested by gas
Water-sealed bearing it is whether qualified；This structure, easy to operate, test is quick, stabilization, and especially test process and result are respectively provided with
Reliability higher.
Preferably, also including briquetting, briquetting bottom sets O-ring seal.Pushed by briquetting, sealing ring transmission is pushed
Power is simultaneously sealed, and makes that the pressure suffered by each position of the inner ring of water-sealed bearing 12, outer ring is more balanced, and sealing effectiveness is more preferable.
Preferably, described briquetting middle part apertured, Kong Zhongshe fixing bolts, the end of thread end of fixing bolt screws
In annular table.Fixing bolt is located at briquetting center, and the pressure suffered by briquetting is most uniform, and the reliability of sealing is significantly increased, and not
The sight line of observer is easily blocked, is easy to observe exactly.
Preferably, described annular groove side wall sets gas port, gas port leads to the lateral wall of pedestal and in collar extension
Connector is set.It is easy to connecting pipe, is difficult to intercept sight line.
Preferably, described connector pipeline is connected with the switch valve for manually or electrically controlling.Facilitate operator according to
The break-make and the duration of test of the state control gas of operation, testing efficiency are high.
Therefore, the utility model provides the detection means that can be sealed in water-sealed bearing in test fluid, using pressure gas
The water resistance of water-sealed bearing is surveyed in physical examination；Easy to operate, test is quick, stabilization, test process and result be respectively provided with it is higher can
By property.
Brief description of the drawings
Accompanying drawing 1 is a kind of structural representation of the utility model water-sealed bearing verifying attachment.
Specific embodiment
Below by embodiment, and with reference to accompanying drawing, the technical solution of the utility model is described in further detail.
Embodiment：The utility model water-sealed bearing verifying attachment, as shown in Figure 1, it includes pedestal 1, and the top of pedestal 1 is opened
If the test groove 2 of accommodating liquid, test groove 2 is recessed into bearing locating slot 3 under bottom；Set in the middle part of the bottom land of bearing locating slot 3
The annular groove 4 connected with external air source, the cylinder of the middle part of annular groove 4 wrapping constitutes supporting table 5, the outside of annular groove 4
The groove bottom of bearing locating slot 3 constitutes annular table 7；O-ring seal 6 is respectively provided with supporting table 5 and annular table 7.Supporting table 5 and annular
O-ring seal 6 on platform 7, corresponds to the inner ring side wall and outer ring side wall of water-sealed bearing to be tested 12 respectively.
During test, water-sealed bearing 12 is pressed against in the supporting table 5 and annular table 7 in bearing locating slot 3, and pressing mode has
Certain position of various ways, such as operator on the upside of subordinate pressure water-sealed bearing 12, the advantage of this waterproof makes cost
It is low, it is transferred to pressing action at once after the completion of the action for placing water-sealed bearing 12 manually, operation is coherent, and speed is fast, but shortcoming is same
Substantially, pressing action pressure is uneven for sample, is easily caused partially sealed not tight and influences testing result.Preferably it is pressed against as one
Scheme is, also including briquetting 9, the bottom of briquetting 9 sets O-ring seal 6.During test, briquetting 9 is pushed, briquetting 9 pushes down water-sealed bearing
12 inner ring lateral wall, and sealing is formed by the O-ring seal 6 on briquetting.This side pushed by briquetting and sealing ring
Formula, makes that the pressure suffered by each position of the inner ring of water-sealed bearing 12, outer ring is more balanced, and sealing effectiveness is more preferable.
Briquetting 9 is pressed against the mode of the inner ring of water-sealed bearing 12, it would however also be possible to employ various ways, such as in water-sealed bearing 12 and pressure
After block 9 is in place, the hold-down devices driven by outer inside casing are moved down, and push down briquetting 9.Choosing is available for as one
The preferred version selected, the middle part apertured of 9 briquetting of briquetting 9, Kong Zhongshe fixing bolts 8, the end of thread end of fixing bolt 8 is screwed in ring
On shape platform 7.After briquetting 9 is in place, fixing bolt 8 is screwed, briquetting 9 is pressed against the inner ring of water-sealed bearing 12；This mode,
Because fixing bolt 8 is located at the center of briquetting 9, pressure is most uniform, and the reliability of sealing is significantly increased, and is difficult to block observer's
Sight line, broad view, whether be easy to accurately and rapidly observe test in groove 2 has bubble to escape.
The side wall of annular groove 4 sets gas port 10, and gas port 10 leads to the lateral wall of pedestal 1 and sets connector in collar extension
11.Located at side wall, it is easy to connecting pipe, than being easy to the overall fixation of device located at bottom, is regarded than being less susceptible to obstruct located at top
Line.
The pipeline of connector 11 is connected with the switch valve for manually or electrically controlling.Facilitate operator according to the state of operation, control
The break-make of gas processed and the duration of test, improve testing efficiency, improve energy resource consumption.
When using, water-sealed bearing 12 to be tested is kept flat in bearing locating slot 3, the outer ring side wall of water-sealed bearing 12
It is pressed against in the O-ring seal in annular table 7, the inner ring side wall and pressure of water-sealed bearing 12 leans against the O-ring seal in supporting table 5
On；Briquetting 9 is pressed against on the inner ring lateral wall of water-sealed bearing 12 again, is inserted fixing bolt 8 and is screwed in annular table 7；Its
Afterwards, in the test injection test fluid of groove 2, open external air source and pressed gas are sent into annular groove 4, in observation test groove 2
Test fluid whether there is gas to escape；Within the testing time of preseting length, depending on there is bubble-free to escape, judgement is test for waterproof
Whether bearing 12 is qualified.
