[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0027] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0028] Reference Figures 1 to 8 As shown, the present invention provides a cutting device for aircraft manufacturing and processing, including a coolant tank 1, a cover plate 2 fixedly connected to the top of the coolant tank 1, a protective shell 3 fixedly connected to the top of the cover plate 2, the bottom end of the protective shell 3 communicating with the coolant tank 1 through the cover plate 2, a fixing plate 4 fixedly connected to the top of the protective shell 3, a shock-absorbing and energy-absorbing part fixedly connected to the middle of the bottom end of the fixing plate 4, the shock-absorbing and energy-absorbing part being located inside the protective shell 3, the bottom end of the shock-absorbing and energy-absorbing part being fixedly connected to the top of the cover plate 2, a lifting part being provided inside the protective shell 3, a cutting mechanism being threadedly connected to the lifting part, the cutting mechanism being sleeved on the outside of the shock-absorbing and energy-absorbing part and in contact with the shock-absorbing and energy-absorbing part, an anti-splashing part being provided on the outside of the bottom end of the cutting mechanism, a cooling and heat-reducing part being fixedly connected to the inner side wall of the anti-splashing part, the cooling and heat-reducing part corresponding to the bottom end of the cutting mechanism, a raw material clamping part and a filter anti-clogging part being provided at the bottom end of the cover plate 2, the raw material clamping part and the filter anti-clogging part being located on both sides of the cutting mechanism respectively, and a feed hole 8 being opened at the bottom of the side wall of the protective shell 3, the feed hole 8 corresponding to the raw material clamping part.
[0029] Furthermore, the top of the outer shell 3 is fixedly connected to the bottom of four vertically arranged support rods 5, and the fixing plate 4 is fixedly connected to the top of the four support rods 5. A central hole 7 is opened in the middle of the top wall of the protective shell 3, and the central hole 7 makes way for the top of the cutting mechanism and the shock absorption part.
[0030] The anti-splash section installed at the bottom of the cutting mechanism provides protection, effectively blocking debris generated during the cutting process and preventing it from flying outside the equipment and causing injury to personnel, thus increasing safety. The anti-clogging filter section effectively filters the coolant circulating inside the equipment, removing solid debris mixed in with the coolant and preventing it from clogging the nozzles during use. The raw material clamping section effectively clamps and fixes the raw material to be cut, preventing it from loosening during the cutting process and ensuring the final cutting effect. The shock absorption section absorbs the vibration generated when the cutting mechanism cuts the raw material, ensuring the stability of the overall equipment operation.
[0031] The design is further optimized. The cutting mechanism includes a lifting plate 10, with both ends of the lifting plate 10 threadedly connected to the lifting part. The lifting plate 10 is slidably mounted inside the protective shell 3. The top of the lifting plate 10 is fixedly connected to the bottom of four vertically arranged connecting rods 12. The tops of the four connecting rods 12 are all fixedly connected to a support plate 9. The support plate 9 is located in the middle of the lifting part. The top of the support plate 9 is fixedly connected to the top of the cutting part. The bottom of the cutting part is rotatably mounted inside the lifting plate 10. The anti-splash part is located outside the bottom of the cutting part. The top of the anti-splash part is fixedly connected to the bottom of the lifting plate 10. The support plate 9 and the lifting plate 10 are sleeved on the outside of the shock-absorbing and energy-absorbing part and are in contact with the shock-absorbing and energy-absorbing part.
[0032] Furthermore, the two short sides of the lifting plate 10 are respectively fixedly connected to the middle part of the limiting ears 19, and the two opposite inner sidewalls of the protective shell 3 are respectively provided with limiting grooves 41. The limiting ears 19 correspond one-to-one with the limiting grooves 41 and are slidably disposed in the limiting grooves 41. The cooperation between the limiting ears 19 and the limiting grooves 41 can ensure that the lifting plate 10 can slide normally up and down inside the protective shell 3.
[0033] Furthermore, the lifting plate 10 has two shock-absorbing holes 29, and the shock-absorbing and energy-absorbing parts are respectively set in the corresponding shock-absorbing holes 29.
[0034] The design is further optimized. The cutting section includes a second motor 23, which is fixedly connected to the top of the support plate 9. The output shaft of the second motor 23 is fixedly connected to a drive sprocket 24. The top of a transmission chain 25 is driven to the outside of the drive sprocket 24. A receiving hole is opened in the middle of the lifting plate 10. A rotating shaft 28 is rotatably connected to the middle of the inner side wall of the receiving hole. A cutting blade 26 and a driven sprocket 27 are fixedly connected to the outer side wall of the rotating shaft 28. Both the cutting blade 26 and the driven sprocket 27 are located in the receiving hole. The bottom end of the transmission chain 25 moves through the support plate 9 and is driven to the outside of the driven sprocket 27. A splash-proof part is set on the outside of the cutting blade 26.
[0035] Furthermore, the cover plate 2 is provided with a cutting hole 14 and a flow-stopping hole 15. The cutting hole 14 is located directly below the bottom end of the cutting blade 26, and the flow-stopping hole 15 is located between the cutting hole 14 and the raw material clamping part. A limiting plate 18 is provided on the side of the cutting hole 14 away from the flow-stopping hole 15, and the limiting plate 18 is fixedly connected to the top end of the cover plate 2.
[0036] The cutting hole 14 makes way for the cutting blade 26 to ensure that the cutting of raw materials can be carried out normally. The throttling hole 15 is used to throttle the coolant circulating in the equipment to ensure that the coolant circulates normally in the equipment and does not flow out of the equipment. The limiting plate 18 limits the raw material to be cut to prevent the raw material from extending too far into the equipment.
[0037] After the raw material to be cut is fixed, the first motor 6 drives the first lead screw 11 to rotate, which in turn drives the lifting plate 10 to descend. The lifting plate 10 descends until the cutting blade 26 effectively contacts the material to be cut. Then the second motor 23 works, driving the cutting blade 26 to rotate at high speed through the transmission chain 25 to cut the raw material.
[0038] The design is further optimized. The anti-splash part includes an anti-splash inner shell 33, which is located outside the cutting blade 26. The top of the anti-splash inner shell 33 is fixedly connected to the bottom of the lifting plate 10. An anti-splash outer shell 34 is slidably sleeved on the outside of the anti-splash inner shell 33. Several connecting springs 35 are fixedly connected to the bottom of the top of the anti-splash outer shell 34. The top of the connecting springs 35 is fixedly connected to the bottom of the lifting plate 10. When the connecting springs 35 are in a free state, the bottom of the anti-splash outer shell 34 is flush with the bottom of the cutting blade 26.
[0039] After the cutting disc 26 makes effective contact with the material to be cut, the splash guard 34 also makes contact with the material to be cut. While the splash guard 34 is in contact with the raw material, it compresses the connecting spring 35. The connecting spring 35 applies force to the splash guard 34 through its own elasticity, ensuring that the splash guard 34 is in contact with the surface of the raw material, effectively protecting the cutting disc 26 and the cutting area, and preventing debris generated during the cutting process from flying and injuring people. When the cutting disc 26 is not cutting the raw material, the splash guard 34 can also protect the cutting disc 26 and prevent damage to the cutting disc 26 due to improper operation.
[0040] Further optimizing the design, the shock absorption and energy absorption section includes two shock absorber rods 20, which are vertically arranged and spaced apart. The top of the shock absorber rod 20 is fixedly connected to the bottom of the fixed plate 4, and the bottom of the shock absorber rod 20 passes through the support plate 9 and the lifting plate 10 in sequence and is fixedly connected to the top of the cover plate 2. The side walls of the two shock absorber rods 20 near the second motor 23 are fixedly connected to a second shock absorber plate 22 by a number of second shock absorber springs 32. The second shock absorber plate 22 contacts the support plate 9 and the lifting plate 10. The number of second shock absorber springs 32 are equally spaced. The side walls of the two shock absorber rods 20 near the cutting plate 26 are fixedly connected to a first shock absorber plate 21 by a number of first shock absorber springs 31. The first shock absorber plate 21 contacts the support plate 9 and the lifting plate 10. The number of first shock absorber springs 31 are equally spaced.
[0041] Vibration is generated during the cutting process of the cutting blade 26. The vibration energy is transmitted to the first damping plate 21 and the second damping plate 22 through the lifting plate 10, and then to a number of first damping springs 31 and second damping springs 32. The vibration energy is absorbed by the compression of the first damping springs 31 and the second damping springs 32, ensuring the overall stability of the equipment during the cutting process.
[0042] The cooling and heat dissipation section includes a booster pump, which is installed in the coolant tank 1. The coolant tank 1 is filled with coolant, and the booster pump is located below the surface of the coolant. One end of the booster pump outlet is fixedly connected to a connecting hose, and the other end of the connecting hose is fixedly connected to several nozzles. The nozzles are fixedly connected to the two opposite inner walls of the splash-proof inner shell 33, and the nozzles are evenly and symmetrically arranged on both sides of the cutting blade 26.
[0043] During the cutting of raw materials, the lift pump works continuously to pump the coolant in the coolant tank 1 into the nozzle and spray it out. The coolant is sprayed onto both sides of the cutting blade 26 to cool the cutting blade 26 and prevent the cutting blade 26 from getting too hot.
[0044] The scheme is further optimized. The lifting part includes two first motors 6. The first motors 6 are fixedly connected to the top of the outer side of the protective shell 3. The output shaft of the first motor 6 is fixedly connected to the top of the vertically set first lead screw 11. The first lead screw 11 is set inside the protective shell 3. The two first lead screws 11 are respectively threaded to both ends of the lifting plate 10. The bottom end of the first lead screw 11 is threaded to the top of the cover plate 2.
[0045] The solution is further optimized. The filter anti-clogging part includes two leakage holes 13 on the cover plate 2. At least three filter tubes 39 are detachably connected to the bottom of the leakage holes 13. Several filter holes 40 are opened at the bottom of the filter tubes 39. The top of the filter tube 39 located above is detachably connected to the bottom of the leakage hole 13. The top of the filter tube 39 located in the middle is detachably connected to the bottom of the filter tube 39 located above. The top of the filter tube 39 located below is detachably connected to the bottom of the filter tube 39 located in the middle. The diameter of the several filter holes 40 at the bottom of the three filter tubes 39 decreases from top to bottom. A magnetic suction plate 30 is provided at the top of one of the leakage holes 13.
[0046] After the used coolant enters the filter tube 39, it passes through the three filter holes 40 of the filter tube 39 from top to bottom. At the same time, the diameter of the filter holes 40 decreases from top to bottom. This arrangement allows the upper filter holes 40 to filter larger impurities, while the lower filter holes 40 filter smaller impurities. Filtering impurities according to particle size can reduce the frequency of clogging of the filter holes 40, while also ensuring the filtration effect.
[0047] The design is further optimized by including two third motors 36 in the material clamping part. The output shafts of the two third motors 36 are arranged opposite to each other. One end of a horizontally arranged third lead screw 37 is fixedly connected to the output shaft of the third motor 36. The bottom end of a clamping block 17 is threadedly connected to the outer wall of the third lead screw 37. The other ends of the two third lead screws 37, which are close to each other, are rotatably connected to the same fixed seat 38. The top end of the fixed seat 38 is fixedly connected to the bottom end of the cover plate 2. Two strip-shaped sliding holes 16 are opened on the cover plate 2. The clamping block 17 corresponds to the strip-shaped sliding hole 16 and is slidably arranged in the strip-shaped sliding hole 16.
[0048] The third motor 36 drives the third lead screw 37 to rotate, thereby enabling the two clamping blocks 17 to effectively fix and clamp the raw material to be cut. At the same time, as the cutting proceeds, the two clamping blocks 17 can also continuously clamp the raw material under the rotation drive of the third lead screw 37, ensuring the fixed clamping effect.
