Abstract
The invention belongs to the field of aviation fuel, and particularly relates to a locking method for connection of cylindrical surfaces. The method comprises the following steps of processing a starting hole in an inner cylindrical surface; processing an inner annular groove on an outer cylindrical surface at the same height, and processing a locking hole in any position of the annular groove; sheathing the inner cylindrical surface into the outer cylindrical surface, inserting the starting end of a fuse into the inner cylindrical surface through the starting hole, rotating the outer cylindrical surface in the direction of the fuse until the terminating end of the fuse falls into the locking hole, and completing the locking. The locking method for the connection of the part cylindrical surfaces has the advantage that additional fasteners and connecting structures are not needed, so the weight is reduced and the space is saved, the assembly and disassembly are simple and rapid, and the safety and reliability in use are realized.
Description
Technical field
The invention belongs to Aviation Fuel field, particularly relate to the locking method connecting between a kind of cylndrical surface.
Background technique
Locking connection between at present domestic fuel oil accessory class product cylndrical surface generally adopts fastening piece to connect locking.Employing fastening piece connects, and needs additional designs linkage structure need to design extra linkage structure, has increased product weight, volume and number of parts when realizing part function.
Destroy 15 aircrafts because take-off and landing distance on warship shortens greatly, the complete machine weight of take-off and landing is very limited, so complete machine loss of weight problem is just particularly important.And the fuel oil annex of destroying 15 aircrafts is more, between the part cylindrical of various products, connect also a lot, when realizing part, product function, how loss of weight has just become matter of utmost importance.
Summary of the invention
Object of the present invention: design the locking method that between a kind of part, cylndrical surface connects, do not need additionally to lock linkage structure and fastening piece, alleviate the number of parts of the weight of product, the volume that reduces product and minimizing product.
Technological scheme of the present invention: the locking method connecting between a kind of cylndrical surface, the locking between inside and outside two cylndrical surface, comprises the following steps:
At inner cylindrical surface, process a starting point hole;
At external cylindrical surface equal height, process an interior circular groove, and process a locking hole in the arbitrary position of circular groove;
Stainless Steel Wire is bent to S shape, as safety fuse cutout;
Inner cylindrical surface is inserted in to external cylindrical surface, the starting point of safety fuse cutout is inserted into inner cylindrical surface through starting point hole, along the direction rotation external cylindrical surface of safety fuse cutout, until the clearing end of safety fuse cutout falls into locking hole, complete locking.
Beneficial effect of the present invention: the present invention does not need additional space design connection locking structure, does not need extra fastening piece to lock, and is conducive to the weight reduction of Aviation Fuel series products and volume; The present invention processes simply, installs and removes convenient, fast, does not need extra instrument to be conducive to increase work efficiency.
Accompanying drawing explanation:
Fig. 1 is the structural representation that the present invention is applied to destroy 15 aircrafts confessions, oil transfer pump;
Fig. 2～Fig. 4 is the locking mechanism schematic diagram of union piece in the present invention;
Wherein, 1-inner cylindrical surface, 2-starting point hole, 3-external cylindrical surface, circular groove in 4-, 5-locking hole, 6-safety fuse cutout, 7-starting point, 8-clearing end.
Specific implementation method
The locking method that cylndrical surface connects, for the locking between inside and outside two cylndrical surface, take that to use the Stainless Steel Wire that diameter is 1mm be example, comprises the following steps:
On inner cylindrical surface 1, processing a degree of depth is the starting point hole 2 that 3mm, diameter are 1.1mm;
At external cylindrical surface 3 equal heights, processing a degree of depth is 0.6mm, and width is circular groove 4 in 1.2mm, and in the arbitrary position of interior circular groove 4, processes a locking hole 5;
Stainless Steel Wire is bent to S shape, and bending goes out starting point 7 and clearing end 8 respectively, as safety fuse cutout 6;
Inner cylindrical surface 1 is inserted in to external cylindrical surface 3, the starting point of safety fuse cutout 67 is inserted into inner cylindrical surface 1 through starting point hole 2, along the direction rotation external cylindrical surface 3 of safety fuse cutout 6, until the clearing end 8 of safety fuse cutout 6 falls into locking hole 5, complete locking.
