Description
Technical field
The utility model relates to a kind of positioning devices precisely cut for airplane heat exchanger.
Background technique
The cutting of airplane heat exchanger generally uses vertical band sawing machine, small, easy to operate with cutting efficiency height, joint-cutting
The advantages of.Currently, workshop is supported and is compressed using plank of various shapes when heat exchanger is cut, human assistance into
Row positioning.However, since heat exchanger shape and structure is complicated, there are irregular plane, be easy to produce clamping it is unstable, can not
The problem of precise positioning cutting part.If pointing device design is unreasonable, joint-cutting contraposition inaccuracy easily causes heat exchanger
Damage.
Utility model content
Technical problem to be solved in the utility model is just to provide and a kind of determines for what airplane heat exchanger was precisely cut
Position device is precisely cut using the positioning device of the utility model, it can be achieved that clamping is steady, cutting part is accurately positioned when cutting
The purpose cut.
Above-mentioned technical problem is solved, the technical solution adopted in the utility model is as follows：
A kind of positioning device precisely cut for airplane heat exchanger, it is characterized in that including：
One support base has a clinoplain 1 (several elongate holes on surface are lightening holes), corresponds to heat and hands over
The bottom surface of parallel operation；The side of the bottom horizontal of clinoplain 1, it is vertical to have an inclined elongated plates 3, the core corresponding to heat exchanger
Body；Both clinoplain 1 and elongated plates 3 constitute V-type, corresponding to the angle between the core and bottom surface of heat exchanger；Inclination
Plane 1 and elongated plates 3 are equipped with groove 2, the cold road flange corresponding to heat exchanger between the two；
One compresses cushion block, has the cylindrical arcuate surface 4 of the cooperation hot road pipeline external surface of heat exchanger；
The support base and compression cushion block is respectively to support, compress heat exchanger.
The elongated plates 3 tilt 60 degree.
It is also equipped with fine tuning rubber mat.Rubber mat is available or unavailable.
Beneficial effect：This positioning device is designed according to heat exchanger resemblance, can be with its exact matching, and clamping is steady,
And it can achieve the purpose that precisely to cut to carry out the rapid fine adjustment of position in conjunction with cross laser alignment device；Finely tune rubber mat, energy
Realize fine adjustment function when cutting；Cushion block is compressed, is cambered design with heat exchanger mating surface, realizes with the complete of heat exchanger
It matches, not defective component, moreover it is possible to be fixedly secured.
Detailed description of the invention
The utility model is described in further detail in the following with reference to the drawings and specific embodiments：
Fig. 1 is the support base stereoscopic schematic diagram of the utility model；
Fig. 2 is the compression cushion block stereoscopic schematic diagram of the utility model；
Fig. 3 is heat exchanger schematic diagram；
Fig. 4 be heat exchanger be in be supported, compress, cut state schematic diagram.
Appended drawing reference in figure is expressed as follows：The bottom surface 1- support plate, 2- flange positioning groove, 3- core fixed block, 4-
Heat exchanger mating surface.
Specific embodiment
Referring to Fig. 1 and Fig. 2, the positioning device embodiment precisely cut for airplane heat exchanger of the utility model, packet
It includes：One support base has a clinoplain 1 (several elongate holes on surface are loss of weight fabrication holes), corresponds to heat and hands over
The bottom surface of parallel operation；The side of the bottom horizontal of clinoplain 1, it is vertical to have an inclined elongated plates 3, the core corresponding to heat exchanger
Body；Both clinoplain 1 and elongated plates 3 constitute V-type, corresponding to the angle between the core and bottom surface of heat exchanger；Inclination
Plane 1 and elongated plates 3 are equipped with groove 2, the cold road flange corresponding to heat exchanger between the two；One compresses cushion block, has
Cooperate the cylindrical arcuate surface 4 of the hot road pipeline external surface of heat exchanger；Support base and compression cushion block are respectively to support, compress
Heat exchanger.Elongated plates 3 tilt 60 degree, are also equipped with fine tuning rubber mat.
The localization method that airplane heat exchanger is precisely cut is carried out using described device, is included the following steps：
The bottom surface of heat exchanger is placed on the clinoplain 1 of support base by S1, cold road flange is placed in flange positioning
On groove 2, core is placed on core fixed block 3；
The hot road pipeline of the column curved surfaces 4 for compressing cushion block and heat exchanger to good position and is laid flat whole by S2；
S3 compresses cushion block with the fixed link that band sawing machine carries；
S4 is directed at heat exchanger weld seam to be cut using the cross laser of the cross laser projection arrangement on band sawing machine；
S5 then unclamps fixed link if you need to finely tune, and increases fine tuning rubber mat on demand on clinoplain 1 and core fixed block 3；
S6 is fixed bar again, starts to cut.
