Abstract
The invention relates to an in-metal complex hole series integrated plate airtightness detection technique which is suitable for high-strength aluminum alloy complex hole series integrated plate airtightness detection and belongs to the fluid airtightness detection technique. The detection technique is characterized by determining dimensions of upper and lower templates according to the size of an integrated plate, and preparing closed surface periphery, so that a test die is made; putting the test die into the water and opening an air injection valve switch; and when a pressure gage reaches 15 kg, closing the air injection valve switch, and observing change of the pressure gage. Therefore, whether the integrated plate is qualified or not is detected according to the change of the pressure gage. The detection technique has the advantages of being low in investment, simple and quick in detection method, and convenient to carry out mass detection and the like.
Description
Technical field
The present invention relates to the inspection technology that a kind of metal inside complicated hole assembly becomes plate tightness, be applicable to the inspection that high-strength aluminum alloy complicated hole assembly becomes plate tightness, belong to Fluid Sealing detection technique.
Background technology
Due to develop rapidly that is economic and technology, the industry of advanced pneumatic control and equipment is adopted to get more and more.A large amount of high-strength aluminum alloy complicated hole system circuit board needs scientific and effective detection means.Particularly a large amount of gas circuit of being provided with of metal inside and the integrated form subassembly be connected with outside, its sealing is related to the safety of working equipment and the problem of normal work.
Summary of the invention
A kind of metal inside complicated hole assembly is the object of the present invention is to provide to become the inspection technology of plate tightness.It can detect the sealing of gas path plate effectively.
To achieve these goals, the present invention adopts technical scheme to comprise: 1. the size becoming board size determination bolster by high-strength aluminum alloy complicated hole assembly, patrix processing gas inlet mouth, and surrounding, every 30 millimeters, processes locking screw holes; 2., according to the complicated hole system circuit board shape fabricating sealing surface surrounding thickness G reatT.GreaT.GT3 millimeter of different high-strength aluminum alloys, wide about 50 millimeters of sealing gaskets, if run into pore in 50 millimeters, edge, remove sealing strip blocking portion; 3. the pore of the complicated hole system circuit board surrounding of high-strength aluminum alloy is clogged with sealing screw plug; 4. lower die face arranges sealing gasket by high-strength aluminum alloy complicated hole system circuit board profile, puts workpiece, sealing gasket put by workpiece, then put mould, locking test mould surrounding screw; 5. test mould is flooded in water and open qi of chong channel ascending adversely threshold switch, close gas when tensimeter reaches 15 kilograms, observe tensimeter change.
It is low that the present invention has equipment investment, and method of testing is simple, rapid, is convenient to the advantages such as mass detection.
Embodiment
Example: select a length and width, the thick high-strength aluminum alloy complicated hole system circuit board being respectively 27cm, 25cm, 2.5cm, produce the upper and lower mould of correspondingly-sized, i.e. locking test mould.And on patrix processing gas inlet mouth, surrounding is every 30 millimeters, processing locking screw holes, then make sealing surface surrounding thickness G reatT.GreaT.GT3 millimeter, wide about 50 millimeters of sealing gaskets, then remove sealing strip blocking portion, the pore of sealing screw plug plug surrounding, sealing gasket is set at lower die face, sealing gasket is arranged and puts workpiece, put above workpiece and be set up die face, and sealing gasket is set between upper die face and workpiece, locking test mould surrounding screw.Test mould is flooded in water and opens qi of chong channel ascending adversely threshold switch, close gas when tensimeter reaches 15 kilograms, observe tensimeter change.According to the method described above.If tensimeter has larger change, then first answer the sealing of checkout mould, after getting rid of this problem, if tensimeter still has larger change, this high-strength aluminum alloy complicated hole system circuit board is defective.Generally (client or design separately have except requirement) is if steadily motionless within tensimeter half an hour, then high-strength aluminum alloy complicated hole assembly becomes plate tightness, functionally reaches requirement.
Claims (1)
1. a metal inside complicated hole assembly becomes the inspection technology of plate tightness, it is characterized in that adopting technical scheme to comprise: 1). the size of board size determination bolster is become by high-strength aluminum alloy complicated hole assembly, patrix processing gas inlet mouth, surrounding, every 30 millimeters, processes locking screw holes; 2). according to the complicated hole system circuit board shape fabricating sealing surface surrounding thickness G reatT.GreaT.GT3 millimeter of different high-strength aluminum alloys, wide about 50 millimeters of sealing gaskets, if run into pore in 50 millimeters, edge, remove sealing strip blocking portion; 3). the pore of the complicated hole system circuit board surrounding of high-strength aluminum alloy is clogged with sealing screw plug; 4). lower die face arranges sealing gasket by high-strength aluminum alloy complicated hole system circuit board profile, puts workpiece, sealing gasket put by workpiece, then put mould, locking test mould surrounding screw; 5). test mould is flooded in water and opens qi of chong channel ascending adversely threshold switch, close gas when tensimeter reaches 15 kilograms, observe tensimeter change.
