As a kind of optimal way of the present invention, the pressure of malleation input port 14 input is preferably the gas of 1Kg.
Specific works principle and method of adjustment are as follows:
After being assemblied on turning arm 3 by lower air cylinder 1, the external part at cylinder assembles guide post 2 and trim ring 5, forms rotating arm component.
Table top 12 is loaded onto rotating shaft 6 and fixing axle 10 respectively.The rotating arm component assembled is loaded the upper end of rotating shaft 6 by two bearings 4 and correlated parts and is used nut check.
Holding the handle on turning arm 3 makes whole assembly rotate around rotating shaft 6, and guiding mechanism makes the draw-in groove 18 on turning arm 3 pass in and out the step groove on fixing axle 10 flexibly.The design of rotating arm component is to facilitate being placed and taken out of tested part.
Upper surface at table top 12 assembles aqua storage tank 11, and uses fluid sealant at contact surface, it is ensured that water-tight after assembling.
First assemble air pressure storehouse 13 at the lower surface of table top 12, use fluid sealant at contact surface equally.After snakelike standpipe 15, rising cylinder 16 being connected by correlated parts again, after the upper end of snakelike standpipe 15 is used fluid sealant, load the lower surface of table top 12.The lower end of rising cylinder 16 is fixed on the fixing point below equipment.
Tow sides at sealing ring 8 are respectively charged into O 9, are then placed in table top 12 hole.Source of the gas is accessed in malleation input port 14.Appropriate water 17 is loaded in snakelike standpipe 15.Assemble complete.
During work, operator puts into Oil pump flange 7 in the hole of sealing ring 8.Then, hold the handle on turning arm 3 and make whole rotating arm component rotate around rotating shaft 6, make the draw-in groove 18 on turning arm 3 enter the step groove on fixing axle 10.Position sensor is lower air cylinder 1 action after receiving signal, drives trim ring 5 Oil pump flange 7 and sealing ring 8 to be compressed.
Then, rising cylinder 16 works and the extruding of snakelike standpipe 15 makes its internal water surface gradually rise.Rising cylinder 16 action puts in place, and just Oil pump flange 7 is all flooded by the water surface.
Then, control system command and be about 1Kg gas at malleation input port 14 input pressure.Operator observes whether the water surface has bubble, thus judging whether Oil pump flange 7 seals.
After having detected, barotropic gas stops input row pressure.Rising cylinder 16 is return simultaneously, makes the water surface recover home position.Operator holds handle makes turning arm 3 turn on, and takes out Oil pump flange 7, and test terminates.The single part testing time only needs the about 5-10 second.
Method of adjustment is:
For the Oil pump flange that bore is different, it is necessary to diametrically again make sealing ring according to different flanges and change the O of its upper surface, meanwhile, again making trim ring.Therefore, the present invention can be suitable for the sealing property detection of the Oil pump flange of multiple caliber.
The extruding force that lower air cylinder is formed is the important indicator of this device emulation detection.The principle adjusting extruding force is the admission pressure that the technology according to automobile fuel pump entrucking fastening force requires to converse under lower air cylinder cylinder diameter, then passes through precise pressure regulating valve and admission pressure is fixed as test pressure.
This kind adopts cylinder to drive the mode that trim ring compresses Oil pump flange edge to replace screw fastening or the mode of fillet of screw jam-packed for Oil pump flange along the detecting device of sealing property, improves the clamping speed of seized part under the premise simulating actual jam-packed power completely；Meanwhile, utilize snakelike standpipe that the feature of volume when extruding, can be changed, with cylinder as extruding source, using the water in standpipe as tested media internal recycle Reusability, both improve test speed, and decreased again the waste of water resource.
It is in the Oil pump flange on malleation storehouse along whether having bubble to produce to determine that the method for Oil pump flange sealing instead of high sensitive sensor detection mode by human eye qualitative observation, while improve test speed, greatly reduces equipment cost.
