Abstract
The utility model discloses a kind of welding fixtures for aircraft air inlet thin-walled parts, including bottom plate and the support leg that bottom plate lower part is arranged in, the positioning mould that lateral surface coincide with inner cavity of component face shape is removably installed on the bottom plate, is used for the pressing device of compressing component skirt on bottom plate equipped with several sets around the outside of positioning mould.The utility model accurate positioning reduces manufacturing cost using the light manufacturing cycle for shortening fixture, and undercarriage is difficult, is difficult to guarantee the problem of deflection after effective solution traditional welding welding fixture, improves the dimensional accuracy of part.
Description
Technical field
The utility model relates to a kind of welding fixtures for aircraft air inlet thin-walled parts.
Background technique
In aircraft air inlet thin-walled parts welding process, part as shown in Figure 1, the thin-walled parts post welding distortion amount is big,
In order to control part welding deformation amount, meets shape requirement, usually make whole bottom plate, but whole bottom plate is as follows
Defect: 1, postwelding undercarriage is difficult, it is sometimes desirable to and destroying bottom plate can be only achieved undercarriage requirement, and 2, want to control thin-walled parts shape
Ask, do it is integral, fixture quality waste greatly resource, 3, be easy to damage part, in view of this, it is necessary to design a kind of for flying
The welding fixture of machine air inlet thin-walled parts.
Utility model content
The utility model aim is to overcome the deficiencies of the prior art and provide a kind of weldering for aircraft air inlet thin-walled parts
Welding fixture.
The technical problem solved by the utility model is implemented by the following technical solutions:
A kind of welding fixture for aircraft air inlet thin-walled parts, including bottom plate and the support that bottom plate lower part is arranged in
Foot is removably equipped with lateral surface on the bottom plate and positioning mould that inner cavity of component face shape is coincide, around positioning on bottom plate
The outside of mould is equipped with the pressing device that several sets are used for compressing component skirt.
Further, pressing device includes knurled nut, studs and monoplane pressing plate with holes, and the lower end of studs is worn
The stud bolt hole crossed in the pressing plate groove and bottom plate of monoplane pressing plate is spirally connected, and the upper end of studs is equipped with knurled nut with holes.
Further, bottom plate is equipped with mold location hole, and positioning mould passes through on the cylinder bolt with carrying handle and bottom plate
The positioning of mold location hole.
Further, carrying handle is additionally provided in the positioning mould.
Further, the outside on the bottom plate around positioning mould offers weld seam slot.
The utility model accurate positioning reduces manufacturing cost, effectively using the light manufacturing cycle for shortening fixture
Solve the problems, such as that undercarriage is difficult, is difficult to guarantee deflection after traditional welding welding fixture, improves the dimensional accuracy of part.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of aircraft air inlet thin-walled parts in the prior art；
Fig. 2 is the structural schematic diagram of the utility model preferred embodiment；
Structural schematic diagram when Fig. 3 is the utility model preferred embodiment clamping；
In figure, positioning mould 1, bottom plate 2, cylinder bolt 3, knurled nut 4 with holes, studs 5, monoplane pressing plate 6, support
Foot 7, carrying handle 8, part 9, weld seam slot 21, skirt 91.
Specific embodiment
In order to be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, under
Face combines and is specifically illustrating, and the utility model is further described.
Embodiment 1: referring to fig. 2 --- a kind of welding fixture for aircraft air inlet thin-walled parts shown in Fig. 3, including bottom
Plate 2 and the support leg 7 that 2 lower part of bottom plate is arranged in removably are equipped with lateral surface and 9 inner cavity surface shape of part on the bottom plate
Identical positioning mould 1 is equipped with compression of several sets for 9 skirt 91 of compressing component around the outside of positioning mould 1 on bottom plate 2 and fills
It sets.
Further, pressing device includes knurled nut 4, studs 5 and monoplane pressing plate 6 with holes, under studs 5
The pressing plate groove across monoplane pressing plate 6 is held to be spirally connected with the stud bolt hole on bottom plate 2, the upper end of studs 5 is equipped with annular knurl spiral shell with holes
Mother 4.
Further, bottom plate 2 is equipped with mold location hole, and positioning mould 1 passes through the cylinder bolt 3 with carrying handle and bottom plate 2
On mold location hole positioning.
Further, carrying handle 8 is additionally provided in the positioning mould 1.
Further, the outside on the bottom plate 2 around positioning mould 1 offers weld seam slot 21.
The utility model fixture can correct air inlet thin-wall part by metal plate on fixture, and part 9 is mounted on fixture such as Fig. 3 institute
Show, so that 9 inner cavity of part is close to positioning mould 1 and position, then be bonded by peripheral single side flat clamp with part plane, realize part
Positioning with bottom plate clamps, and welding carrying handle 8 is equipped in positioning mould 1 and with carrying handle cylinder bolt 3, band of dismantling is lifted
The characteristics of handle cylinder bolt 3, can hold welding carrying handle 8 separates positioning mould 1 and bottom plate 2, this device be will originally be one
The fixture of body formula is divided into positioning mould and bottom plate, and positioning mould can realize quick-clamping, facilitates undercarriage on worker operation and part 9, changes
It is difficult into worker operation before, the big problem of deflection after part 9 welds.
The basic principles and main features of the present invention and the advantages of the present invention have been shown and described above.Current row
The technical staff of industry is described in above embodiments and description it should be appreciated that the present utility model is not limited to the above embodiments
Only illustrate the principles of the present invention, on the premise of not departing from the spirit and scope of the utility model, the utility model is also
It will have various changes and improvements, these various changes and improvements fall within the scope of the claimed invention.The utility model
Claimed range is defined by the appending claims and its equivalent thereof.
