Description

Technical Field

[0001] The present invention relates to the field of laser cutting, and particularly to a production device for thin-walled aviation products. Background Art

[0002] During the laser cutting process of thin-walled aviation products, it is necessary to continuously transfer raw materials to the clamping device of the laser cutting machine to achieve automatic feeding of the raw materials of thin-walled aviation products and meet the requirement of automatic continuous cutting. Since the specifications and models of the raw materials that the cutting machine needs to cut are diverse, for example, the profiles have different models such as rectangular, square, hexagonal, etc., and each type of profile has different specifications in terms of size. Different clamping requirements are needed for the feeding of raw materials of each model and specification. The existing feeding devices are not universal, which affects the feeding requirements during the automatic continuous cutting of the laser cutting machine. Summary of the Invention

[0003] In view of the above deficiencies in the prior art, the present invention provides a production device for thin-walled aviation products that can adapt to profiles of different models and specifications and meet the feeding requirements for automatic continuous cutting using a laser cutting machine.

A pushing frame bearing seat at the lower part of the pushing frame is threadedly connected to a second lead screw. The second lead screw is rotatably connected to the frame. A motor is connected to one side of the second lead screw.

[0006] The upper part of the material distribution seat has an inclined material distribution seat inclined surface. The upper part of the material distribution seat inclined surface is connected to the lower left part of the blanking port. The lower part of the material distribution seat is provided with a base. There is a base groove in the middle of the base. There is a base sliding groove below the base groove. There is a base lead screw seat on the left side of the base sliding groove. The side of the base lead screw seat is connected to a third motor. The output shaft of the third motor is connected to a second lead screw. The second lead screw is rotatably connected to the base lead screw seat. The second lead screw is threadedly connected to the base lead screw seat at the lower part of the bottom sliding seat. The bottom sliding seat is slidably connected to the base sliding groove. The vertical plate at the upper part of the bottom sliding seat is fixedly connected to a first cylinder. The telescopic rod of the first cylinder is connected to a stop plate. There are ear plates at the connection between the lower part of the material distribution seat inclined surface and the material distribution seat. Each ear plate is fixedly connected to a second cylinder. The feeding seat is fixed at the lower part of the frame, on the right side of the blanking port. The lower part of the feeding seat has two symmetrically arranged supporting plates. There are two symmetrically arranged roller shaft holes inside the two supporting plates.

[0008] Beneficial effects: The height-adjustable first cylinder of the present invention enables thin-walled aviation product profiles of different specifications and models to be pushed out by the pusher frame. The adjustable stop plate can not only ensure that profiles of each specification are blocked at the bottom of the stop plate and the material distribution seat inclined surface, but also ensure that there is only one profile on the material distribution seat each time, ensuring a gap is generated between the first profile on the material distribution seat and the second profile on the material distribution seat inclined surface, ensuring that the second cylinder can block the second profile and ensuring that the profiles are taken away one by one. When the material lifting device slides past the lower part of the material distribution seat, the intercepting plates on both sides take the profiles away from the side, and the taken profiles fall onto the material lifting frame. This material taking method is not affected by the material specifications and has good adaptability. When the material lifting device brings the material to the upper part of the feeding device, the supporting plate inclined surfaces on both sides of the feeding seat press down the intercepting plates, and the thin-walled aviation product profiles are blocked by the feeding seat and fall onto the belt, also not affected by the material specifications, meeting the feeding requirements for the automatic continuous cutting of the thin-walled aviation product laser cutting machine.

Specific embodiments

[0029] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments:

[0030] Refer to Figure 1 , 2, 3. A production device for thin-walled aviation products, including a material leveling device 100, a material lifting device 200, a material feeding device 300, and a material distributing device 400. The material leveling device 100 includes a frame 110. A blanking port 117 is provided at the end face of the frame 110. The lower part of the blanking port 117 is connected to the material distributing device 400. The material distributing device 400 includes a material distributing seat 410. A bottom sliding seat 420 slides at the lower part of the material distributing seat 410. The bottom sliding seat 420 is connected to a first cylinder 450 and a stop plate 460. Two second cylinders 470 are connected to both sides of the material distributing seat 410. The stop plate 460 and the second cylinders 470 intercept and position the profiles. The frame 110 is connected to a sprocket 170 and a chain 180. The material lifting device 200 is connected between the chains 180. The material lifting device 200 includes a connecting frame 210. Lifting frames 220 slide on both sides of the connecting frame 210. An intercepting plate 230 slides on each lifting frame 220. The material lifting device 200 is responsible for transferring the profiles. The lower part of the frame 110 is connected to the material feeding device 300. The material feeding device 300 includes a material feeding seat 310 and a roller shaft 320 connected to the material feeding seat 310. The material feeding seat 310 and the lifting frame 220 cooperate with each other to transfer the profiles onto the material feeding device 300.

[0031] Reference Figures 4 to 7 , a frame 111 is provided at the upper part of the frame 110. A frame guide groove 113 is provided on the right side of the frame 111. A first lead screw hole 112 is provided at the upper part of the frame guide groove 113. A baffle 150 slides in the frame guide groove 113. The baffle 150 is rotatably connected to a first lead screw 140. The first lead screw 140 is threadedly connected to the first lead screw hole 112. A middle groove 115 is provided on the left side of the frame 110. Two symmetric frame sliding grooves 116 are provided on both sides of the middle groove 115. A pushing frame 120 is provided in the two frame sliding grooves 116. Two pushing frame sliding grooves 122 at the lower part of the pushing frame 120 slide on the frame sliding grooves 116. A pushing frame bearing seat 121 at the lower part of the pushing frame 120 is threadedly connected to a second lead screw 160. The second lead screw 160 is rotatably connected to the frame 110. A motor is connected to one side of the second lead screw 160.

[0032] When using this device, the profiles of the thin-walled aviation products are placed inside the frame 111. Rotate the first lead screw 140 to adjust the height of the baffle 150 so that the space between the lower part of the baffle 150 and the frame 110 is equal to the height of the profiles. When the motor connected to the second lead screw 160 rotates, it drives the second lead screw 160 to rotate. The second lead screw 160 drives the pushing frame 120 to move to the right. The pushing frame 120 pushes the raw materials out to the right from the pushing groove 114 at the lower part of the frame 111. The profiles in the lowermost layer in the frame 111 are pushed out from the gap between the baffle 150 and the frame 110. The pushing frame bearing seat 121 passes through the middle groove 115.

[0033] Reference Figures 15 to 19, an inclined material distribution seat inclined surface 411 is provided on the upper part of the material distribution seat 410. The upper part of the material distribution seat inclined surface 411 is connected to the lower left part of the blanking port 117. A base 413 is provided at the lower part of the material distribution seat 410. A base groove 414 is provided in the middle of the base 413. A base sliding groove 415 is provided at the lower part of the base groove 414. A base lead screw seat 416 is provided on the left side of the base sliding groove 415. A third motor 440 is connected to the side of the base lead screw seat 416. The output shaft of the third motor 440 is connected to a second lead screw 430. The second lead screw 430 is rotatably connected to the base lead screw seat 416. The second lead screw 430 is threadedly connected to a base sliding seat lead screw seat 421 at the lower part of the bottom sliding seat 420. The bottom sliding seat 420 is slidably connected to the base sliding groove 415. A vertical plate 422 at the upper part of the bottom sliding seat 420 is fixedly connected to a first air cylinder 450. The telescopic rod of the first air cylinder 450 is connected to a stop plate 460. An ear plate 418 is provided at the connection between the lower part of the material distribution seat inclined surface 411 and the material distribution seat 410. Each ear plate 418 is fixedly connected to a second air cylinder 470. When the third motor 440 rotates, the third motor 440 drives the second lead screw 430 to rotate. The second lead screw 430 drives the first air cylinder 450 and the stop plate 460 to slide back and forth. The distance between the stop plate 460 and the bottom of the material distribution seat inclined surface 411 is equal to the width of the profile. When the profile is pushed out by the pusher 120, since the pusher 120 pushes out multiple profiles at the lowermost part of the profile at one time, the profile slides down along the material distribution seat inclined surface 411. The lowermost profile falls onto the material distribution seat 410 and is blocked by the stop plate 460. The width of the profile is equal to the distance between the stop plate 460 and the bottom of the material distribution seat inclined surface 411. Therefore, after the lowermost profile falls onto the material distribution seat 410, the second profile is on the material distribution seat inclined surface 411 and the side of the second profile leans against the first profile. There is a gap between the first profile and the second profile. When the telescopic rod of the second air cylinder 470 extends, the telescopic rod of the second air cylinder 470 is inserted into the gap between the first profile and the second profile. The second profile is supported by the telescopic rods of the two second air cylinders 470. When the first profile is taken away, the second profile is still supported by the telescopic rods of the two second air cylinders 470. When the telescopic rods of the two second air cylinders 470 are reset, the profiles on the material distribution seat inclined surface 411 can continue to slide down. The adjustable stop plate 460 can not only ensure that profiles of each specification are blocked between the stop plate 460 and the bottom of the material distribution seat inclined surface 411, but also ensure that there is only one profile on the material distribution seat 410 each time, ensuring that there is a gap between the first profile on the material distribution seat 410 and the second profile on the material distribution seat inclined surface 411, ensuring that the second air cylinder 470 can block the second profile, and ensuring that the profiles are taken away one by one.

[0034] Reference Figures 12 to 14, the feeding seat 310 is fixed to the lower part of the frame 110, on the right side of the blanking port 117. There are two symmetrically arranged pallets 311 at the lower part of the feeding seat 310. There are two symmetrically arranged roller shaft holes 313 on the inner sides of the two pallets 311. Roller shafts 320 are rotatably connected in the two roller shaft holes 313 respectively. A second motor 340 fixed to the feeding seat 310 is connected to the outside of one of the roller shafts 320. A belt 330 is rotatably connected to the outside of the two roller shafts 320.

[0035] Reference Figures 4 to 7 , there are two front-and-rear symmetrically arranged sprocket seats 118 on the left and right sides of the lower part of the frame 110 respectively. Sprockets 170 are rotatably connected in the two sprocket seats 118 on the left side and the two sprocket seats 118 on the right side respectively. A chain 180 is rotatably connected to the outside of the two sprockets 170. The output shaft of a first motor 190 fixed to the side of the corresponding sprocket seat 118 is connected to the outside of one of the sprockets 170.

[0036] Reference Figures 4 to 7 , a chute plate 130 is fixedly connected to the frame 110 on the outside of each chain 180. The chute plate 130 is provided with a guide groove 131. The guide groove 131 is an elliptical groove that is consistent with the moving track of the chain 180. A protruding pushing groove 132 is provided on the upper part of the guide groove 131.

[0037] Reference Figures 8 to 10 , both sides of the connecting frame 210 are fixed to the corresponding links of the chains 180 on both sides. Symmetrically arranged connecting frame chutes 211 are provided on both sides of the connecting frame 210. A lifting frame 220 is provided in each connecting frame chute 211. Lifting frame sliders 224 on both sides of the lifting frame 220 are slidably connected to the corresponding connecting frame chutes 211. A lifting frame cam rod 225 on the outside of the lifting frame 220 is slidably connected to the guide groove 131. A lifting frame groove 221 is provided on the inner side of the lifting frame 220. A lifting frame bottom plate 222 is provided at the lower part of the lifting frame 220. A lifting frame guide hole 223 is provided on the inner side of the lifting frame bottom plate 222. An intercepting plate 230 is provided in the lifting frame groove 221 and the lifting frame guide hole 223. The intercepting plate 230 is slidably connected to the lifting frame groove 221. An intercepting plate guide rod 231 at the lower part of the intercepting plate 230 is slidably connected to the lifting frame guide hole 223. An intercepting plate cam rod 232 on the side of the intercepting plate 230 abuts against the lower part of the lifting frame 220. A spring 240 is provided between the intercepting plate 230 and the lifting frame 220. The spring 240 is sleeved on the outside of the intercepting plate guide rod 231. The lower part of the spring 240 abuts against the lifting frame bottom plate 222. The upper part of the spring 240 abuts against the intercepting plate 230. In the normal state, the intercepting plate 230 extends out of the end face of the lifting frame 220.

[0038] Reference Figure 3, on both sides of the inclined surface 411 of the material distribution base 410, there are two symmetrically arranged material distribution base grooves 412. On the outer side of each pallet 311 of the feeding base 310, there is a pallet inclined surface 312. When the lifting device 200 rotates to the lower part of the material distribution base 410, the lifting frame 220 slides past the lower part of the material distribution base 410, and the two intercepting plates 230 pass through the middle of the two material distribution base grooves 412. The first air cylinder 450 resets, the stop plate 460 descends, and the two intercepting plates 230 take away the profiles on the material distribution base 410, and the profiles fall onto the two lifting frames 220. When the lifting device 200 rotates to the upper part of the feeding device 300, the intercepting plate cam rod 232 is in sliding connection with the pallet inclined surface 312, and the intercepting plate 230 is driven to descend by the pallet inclined surface 312. When the profile passes through the feeding device 300, the profile is blocked by the feeding base 310 and falls onto the belt 330.

[0039] A method for using a production device for thin-walled aviation products. When using this device, place the thin-walled aviation product profile inside the frame 111. Rotate the first lead screw 140 to adjust the height of the baffle 150 so that the space between the lower part of the baffle 150 and the frame 110 is equal to the height of the thin-walled aviation product profile. Rotate the third motor 440 so that the distance between the stop plate 460 and the bottom of the inclined surface 411 of the material distribution seat is equal to the width of the profile. At this time, the first cylinder 450 operates, and the stop plate 460 extends, while the second cylinder 470 does not operate and the telescopic rod of the second cylinder 470 retracts. The motor connected to the second lead screw 160 starts to rotate, and the pusher frame 120 pushes the raw material out to the right from the material pushing groove 114 at the lower part of the frame 111. The profile on the lowermost layer in the frame 111 is pushed out from the gap between the baffle 150 and the frame 110. When the thin-walled aviation product profile is pushed out by the pusher frame 120, the profile slides down along the inclined surface 411 of the material distribution seat. The lowermost profile falls onto the material distribution seat 410 and is blocked by the stop plate 460. The width of the profile is equal to the distance between the stop plate 460 and the bottom of the inclined surface 411 of the material distribution seat. Therefore, after the lowermost profile falls onto the material distribution seat 410, the second profile is on the inclined surface 411 of the material distribution seat and the side of the second profile leans against the first profile, and there is a gap between the first profile and the second profile. The second cylinder 470 operates, and the telescopic rod of the second cylinder 470 extends. The telescopic rod of the second cylinder 470 is inserted into the gap between the first profile and the second profile, and the second profile is supported by the two telescopic rods of the second cylinder 470. The first motor 190 starts to drive the chain 180 to rotate. The rotation of the chain 180 drives the lifting device 200 to move from the left side to the right side of the material distribution device 400. When the lifting device 200 rotates to the lower part of the material distribution seat 410, the lifting frame 220 slides past the lower part of the material distribution seat 410, and the two intercepting plates 230 pass through the middle of the two material distribution seat grooves 412. The first cylinder 450 resets, and the stop plate 460 descends. The two intercepting plates 230 take away the profile on the material distribution seat 410, and the profile falls onto the two lifting frames 220. Subsequently, the first cylinder 450 starts, the stop plate 460 rises, the second cylinder 470 resets, and the profile falls again. Then the second cylinder 470 operates again, and the profile at the lowermost part of the inclined surface 411 of the material distribution seat is supported again. When the lifting device 200 rotates to the upper part of the feeding device 300, the intercepting plate cam rod 232 is slidably connected to the inclined surface 312 of the support plate, and the intercepting plate 230 is driven to descend by the inclined surface 312 of the support plate. When the profile passes through the feeding device 300, the profile is blocked by the feeding seat 310 and falls onto the belt 330. The second motor 340 starts, and the belt 330 sends out the profile. Thus, the material taking and feeding actions of the profile are completed, realizing the automatic continuous cutting of the laser cutting machine, which can prevent defects such as slag hanging, cracks, etc. from appearing on the laser cutting section. The laser cutting section is neat and has good flatness.

[0040] The first cylinder 450 with adjustable height enables profiles of different specifications and models to be pushed out by the pusher rack 120. The adjustable stop plate 460 can not only ensure that profiles of each specification are blocked at the bottom of the stop plate 460 and the slope of the material distribution seat 411, but also ensure that there is only one profile on the material distribution seat 410 each time, ensuring a gap between the first profile on the material distribution seat 410 and the second profile on the slope of the material distribution seat 411, guaranteeing that the second cylinder 470 can block the second profile and ensuring that the profiles are taken away one by one. When the lifting device 200 slides past the lower part of the material distribution seat 410, the intercepting plates 230 on both sides take the profiles away from the side, and the taken profiles fall onto the lifting rack 220. This material taking method is not affected by the material specifications and has good adaptability. When the lifting device 200 brings the materials to the upper part of the feeding device 300, the supporting plate slopes 312 on both sides of the feeding seat 310 press down the intercepting plates 230, and the profiles are blocked by the feeding seat 310 and fall onto the belt 330. It is also not affected by the material specifications, meeting the feeding requirements for the automatic continuous cutting of the laser cutting machine.
