Specific embodiment
The principles of the present invention and feature are described below in conjunction with attached drawing, example is served only for explaining that this is practical
It is novel, it is not intended to limit the scope of the utility model.
A kind of welding airtightness detection device, including workbench 1, workbench 1 by the columns I 2 of two sides and column II 3 with
Hydraulic press plate 4 is fixedly connected, and column I 2 and column II 3 are flexibly connected lifting platform 5, and top pillar inner core is arranged in the top of workbench 1
6, top pillar inner core 6 is connect by oil pipe 8 with hydraulic press 9 with top pillar 7,5 bottom end vertical columns of lifting platform, places bridge on workbench 1
Shell 10, column fix axle housing 10, bearing block 11 are welded on axle housing 10, and 11 top of bearing block is equipped with polyurethane sheet I 12, polyurethane sheet
I 12 top is equipped with bearing block cover board 13, is equipped with air intake 14, air intake 14 among polyurethane sheet I 12 and bearing block cover board 13
It is connect with tracheae 15 is entered.Column includes column III 16 and column IV 17, and column III 16 is connected on bearing block cover board 13, column IV
17 bottom surface matches with 10 surface of axle housing, and column IV 17 resists 10 surface of axle housing.Poly- ammonia is equipped between workbench 1 and axle housing 10
Ester plate II 18.Column I 2 and column II 3 are equipped with gear 19 and rack gear 20, and lifting platform 5 passes through the cooperation of gear 19 and rack gear 20
It is moved up and down along column I 2 and column II 3.Oil pipe 8 is equipped with manual control valve 21.Workbench 1 is plug-type workbench.It is poly-
Urethane plate I 12 is the polyurethane sheet with piston.
Working principle
Axle housing 10 is located on workbench 1, covers bearing block cover board 13, is pushed into the lower section of hydraulic press plate 4, and starting is manual
Control valve 21 makes to decline top pillar inner core 6 full of hydraulic oil in top pillar 7, drive lifting platform 5 under column I 2 and column II 3
Drop makes the column III 16 of lower section and column IV 17 push down bearing block cover board 13 and axle housing 10, axle housing 10 and polyurethane sheet II just
18 fit closely, and bearing block 11 is sealed by polyurethane sheet I 12, make to form closed chamber inside axle housing 10, be passed through in air intake 14
The pressure-air of certain pressure makes bubble aqueous solution finally to be sprayed around weld seam 22, if weld seam full of high pressure inside axle housing 10
Then apparent bubble can be seen in air-leak section in 22 gas leakage.
