Pressurizing device for rapidly plugging cast oil lines

Abstract

The invention belongs to an oil line pressurizing technology, and particularly relates to a pressurizing device for rapidly plugging two intersecting cast oil lines. According to the invention, an oilline internal tensioning plugging device comprises a locking rod (1), a locking nut (2), a hold-down ring (3), a sealing sleeve (4), a hold-down sleeve (5) and a sealing ring (6), wherein a gas inlethole is formed at the center of the locking rod; a bottom plate is arranged at the right end of the locking rod; the sealing ring is in sleeving connection to the bottom plate end of the locking rod;the right side of the sealing ring is attached to the bottom plate; the inner diameter of the sealing ring is attached to the outer diameter of the locking rod; the hold-down sleeve sleeves the locking rod; the right side of the hold-down sleeve is attached to the left side of the sealing ring; the sealing sleeve sleeves the locking rod; the right side of the sealing sleeve is attached to the left side of the hold-down sleeve; the hold-down ring sleeves the locking rod; and the sealing sleeve and the sealing ring are distributed on both sides of a small oil line (8). The pressurizing device is simple in structure, good in plugging effect and universality and simple and efficient to operate, is applied to a complex oil line pressurizing test for aviation magnesium and aluminum alloy casingtype castings, and has high practical application value.

Description

technical field [0001] The invention belongs to the technology of suppressing oil passages, in particular to a pressing device for rapidly blocking two intersecting casting oil passages. Background technique [0002] Aviation magnesium and aluminum alloy casing castings are usually cast with complex oil circuits and compact structures. When the oil circuit is pressed, the oil circuit orifice needs to be blocked. There are two ways to block: one method is the frame clamp , that is to use a support frame to support and compress the plugging fixture. Another way is to machine the oil passage hole and end face, and process threaded holes on the casting, and then use the blocking cap to lock the sealing Blocking. [0003] The above method has the following disadvantages: 1) Each casting needs to be equipped with a set of special oil circuit pressing fixtures, resulting in great waste; 2) For compact castings with many oil circuit holes, due to space constraints, a set of frame f...

Problems solved by technology

[0003] The above method has the following disadvantages: 1) Each casting needs to be equipped with a set of special oil circuit pressing fixtures, resulting in great waste; 2) For compact castings with many oil circuit holes, due to space constraints, a set of frame fixtures cannot be arranged All plugging covers require multiple sets of frames; 3) The operation of the frame fixture is complicated, and the plugging operation takes a long time; 4) The mechanical processing method needs to process each casting, the processing cycle is long, and the cost of a single casting increases. Castings cannot be threaded yet, and machining methods cannot be used
