[0018] A method for riveting an aluminum shell of an aviation filter, the method comprising the following steps:

[0019] S1: Sealing ring fixing plate placement:

[0020] The sealing ring fixing plates used in the aluminum shell of the aviation filter are sequentially placed on the upper part of the multiple sets of center platforms. Before the sealing ring fixing plates are placed, according to the sizes of the sealing ring fixing plates of different specifications, the electric slider is turned on to rotate the lower ring. The rotation of the lower ring causes the slide plate to slide through the moving groove, and finally the circular holes on the multiple adjusting parts correspond one to one with the multiple circular holes on the sealing ring fixing plates, so as to meet the alignment of the circular holes on the sealing ring fixing plates of different diameters;

[0021] S2: Conveying sealing ring fixing plate and pushing threaded cover plate:

[0022] Before conveying the sealing ring fixing plate in sequence, the first motor is turned on to rotate the multiple drive shafts, and the rotation of the drive shaft drives the support plate to perform a lifting-forward-downward cycle operation in sequence through the telescopic plate, so that the placed sealing ring fixing plate is conveyed to the lowering unit, and then the electric push plate is turned on to push the threaded cover plate riveted with the sealing ring fixing plate to the top of the sealing ring fixing plate;

[0023] S3: Riveting operation:

[0024] After the threaded cover plate is pushed and matched with multiple sealing ring fixing plates, the second push rod is opened according to the spacing between the multiple sealing ring fixing plates. The second push rod is opened to make the multiple alignment plates correspond to the sealing ring fixing plates. Then the electric slider is opened to make the riveting machine slide in the alignment groove until it is coaxial with the circular hole on the sealing ring fixing plate on one side. Then the second motor is turned on to make the driving block drive the multiple through grooves to rotate in turn, so that the riveting machine performs riveting operations on the circular holes on the sealing ring fixing plate and the threaded cover plate in turn.

[0025] Beneficial effects of the present invention:

[0026] 1. When the movable plate moves downward, the lifting cylinder is driven to move downward. At this time, the inclined surface block slides downward along the top of the middle component until it reaches between the middle component and the sliding component to lift the middle component. As the movable plate moves forward, multiple sealing ring fixing plates are driven to be transported forward at equal intervals. As the movable plate is lifted upward, the lifting cylinder is driven to rise. The inclined surface blocks on both sides of the lifting cylinder are separated from the lifting of the middle component. At this time, the clamps on both sides fall above the conveying frame. The movable plate repeatedly moves upward-forward-downward to transport multiple sealing ring fixing plates at equal intervals, so that the threaded cover plates can be placed on them in sequence.

[0027] 2. The present invention drives the lower ring to rotate by opening the electric slider, and when the lower ring rotates, the round block is driven to move through the moving groove. When the round block moves, the slide plate slides in the vertical block, so that the adjusting member slides in the adjusting groove, and finally the riveting holes in the middle of the upper surfaces of the multiple adjusting members correspond one-to-one with the holes opened in the annular direction on the sealing ring fixing plates of different specifications, so as to meet the requirements of riveting the round holes on the sealing ring fixing plates of different diameters.

[0028] 3. In the present invention, when the circular holes on the placed sealing ring fixing plate and the threaded cover plate are riveted in sequence, the riveting unit performs the riveting operation on them, and then the second motor is turned on to rotate the driving plate, and the driving plate rotates to contact with multiple through grooves in sequence through the driving block, so that the circular holes on the sealing ring fixing plate corresponding to the multiple through grooves are rotated to the bottom of the riveting unit in sequence, so that the riveting unit performs the riveting operation on them.

[0029] 4. The present invention rotates the threaded rod to move the upper side plate down to contact the lower side plate, and then turns on the electric push plate to extend and retract to push the threaded cover plate. The electric push plate cooperates with multiple sealing ring fixing plates that are delivered, so as to continuously place the threaded cover plate on the surface of the delivered sealing ring fixing plate.

[0044] An aviation filter aluminum shell riveting device and method, characterized by riveting of aluminum forgings for aerospace, IPC classification number: B21J*;

[0045] like Figure 1-10 As shown, an aviation filter aluminum shell riveting device includes a base 1, a conveying device 2 is fixedly installed in the middle of the upper end surface of the base 1, and the conveying device 2 includes a conveying frame 210 connected to the base 1, and a group of symmetrically arranged driving shafts 211 are correspondingly installed on both sides of the conveying frame 210. The driving shafts 211 are rotatably connected to the conveying frame 210. A pulley 212 is fixedly installed on each of the two driving shafts 211 of the group, and a belt 213 is arranged between the pulleys 212 for transmission. A first motor 214 is fixedly installed on the conveying frame 210 on one side through a motor plate;

[0046] The output end of the first motor 214 is fixedly connected to the drive shaft 211 on one side. One end of the drive shaft 211 is provided with a telescopic plate 215. A connecting rod 216 is rotatably installed between the left and right corresponding telescopic plates 215. Support plates 217 are fixedly installed on both sides of the connecting rod 216. A moving plate 218 is installed between the two support plates 217. A lowering unit 3 is provided on one side of the conveying frame 210, and a riveting unit 4 is fixedly installed on the other side of the conveying frame 210. When the first motor 214 is turned on, the drive shafts 211 are driven to rotate synchronously through the belt pulleys 212 and the belt 213, thereby driving the telescopic plates 215 connected to the drive shafts 211 to rotate. The rotation of the telescopic plates 215 causes the moving plate 218 above the connecting rod 216 to perform repeated upward-forward-downward movements, thereby driving the plurality of seal ring fixing plates above to be conveyed forward at equal intervals. And the telescoping of the telescopic plates 215 facilitates the adjustment of the conveying interval of the seal ring fixing plates during conveying.

As the moving plate 218 moves forward, it drives the plurality of seal ring fixing plates to be conveyed forward at equal intervals. As the moving plate 218 rises upward, it drives the lifting cylinder 222 to rise. The inclined blocks 224 on both sides of the lifting cylinder 222 move away from lifting the middle member 233. At this time, the clamping members 231 on both sides fall above the conveying frame 210.

When the lower ring 242 rotates, the round block 246 is driven to move through the moving groove 243. When the round block 246 moves, the slide plate 245 slides in the vertical block 244 so that the adjusting member 248 slides in the adjusting groove 247. Finally, the riveting holes in the middle of the upper surfaces of the plurality of adjusting members 248 correspond one to one with the holes opened in the annular direction on the sealing ring fixing plates of different specifications, so as to meet the requirements of riveting the round holes on the sealing ring fixing plates of different diameters.

[0063] The pulley 212 and the belt 213 drive the multiple drive shafts 211 to rotate synchronously, thereby driving the telescopic plate 215 connected to the drive shaft 211 to rotate. The rotation of the telescopic plate 215 causes the movable plate 218 above the connecting rod 216 to repeatedly move upward, forward, and downward, thereby driving the multiple sealing ring fixing plates above to be transported forward at equal intervals, and the telescopic plate 215 is telescopic to facilitate the adjustment of the transport spacing of the sealing ring fixing plates during transport. When the movable plate 218 moves downward, it drives the lifting cylinder 222 to move downward, and at this time, the inclined block 224 moves downward along the top of the middle component 233. Slide until it is between the middle component 233 and the sliding component 234 to lift the middle component 233. As the moving plate 218 moves forward, it drives multiple sealing ring fixing plates to be transported forward at equal intervals. As the moving plate 218 is lifted upward, it drives the lifting cylinder 222 to rise. The inclined blocks 224 on both sides of the lifting cylinder 222 move upward and break away from the lifting of the middle component 233. At this time, the clamps 231 on both sides fall above the conveying rack 210. The moving plate 218 repeatedly moves upward-forward-downward to transport multiple sealing ring fixing plates at equal intervals, so that the threaded cover plates can be placed on them in sequence.

[0064] When the circular holes on the placed sealing ring fixing plate and the threaded cover plate are riveted in sequence, the riveting unit 4 performs the riveting operation on them, and then the second motor 254 is turned on to rotate the driving plate 255, and the driving plate 255 rotates and contacts with the multiple through grooves 252 in sequence through the driving block 256, so that the circular holes on the sealing ring fixing plate corresponding to the multiple through grooves 252 are rotated to the bottom of the riveting unit 4 in sequence, so that the riveting unit 4 performs the riveting operation on them, and when the threaded cover plate is pushed on the sealing ring fixing plate conveyed in sequence, the threaded rod 318 is rotated to make the upper side plate 319 move down to contact with the lower side plate 316, and then the electric push plate 324 is turned on to extend and retract to push the threaded cover plate, and the electric push plate 324 cooperates with the multiple conveyed sealing ring fixing plates, so as to continuously place the threaded cover plate on the surface of the conveyed sealing ring fixing plate;

[0065] When riveting multiple sealing ring fixing plates covered with threaded cover plates, the second push rod 48 is turned on to allow the connecting plate 49 to drive the middle alignment plate 47 to slide. At this time, under the action of the shrinkage frame 490, the distance between the multiple alignment plates 47 is adjusted, and then the riveting machine 493 is adjusted to be coaxial with the circular hole on the sealing ring fixing plate. Then, the first push rod 44 is turned on to allow the front side plate 45 to move down to the riveting machine 493 to contact the riveting hole, and then the riveting machine 493 can be turned on to rivet the sealing ring fixing plate and the threaded cover plate.
