[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0023] Embodiment: As Figures 1 - 9 shown, the present invention provides an aircraft engine blade processing device with a heat dissipation mechanism, including an installation bracket 1. A polishing mechanism 2 for cooperation is provided at the upper end of the installation bracket 1, and a heat dissipation mechanism 3 for cooperation with the polishing mechanism 2 is provided at the lower end of the installation bracket 1. A limiting mechanism 4 for cooperation is provided on the heat dissipation mechanism 3. The setting and use of the polishing mechanism 2 improve the processing efficiency of aircraft engine blades. The setting and use of the heat dissipation mechanism 3 can prevent the polishing mechanism 2 from having a local overheating phenomenon and can also prevent the phenomenon of chip scattering. The setting and use of the limiting mechanism 4 facilitate the cleaning of the heat dissipation mechanism 3.

[0024] The polishing mechanism 2 includes a polishing motor 21, an electric telescopic rod 22 and a multi-stage electric push rod 23. The polishing motor 21, the electric telescopic rod 22 and the multi-stage electric push rod 23 are all fixedly installed on the mounting bracket 1. The output end of the polishing motor 21 rotatably penetrates through the mounting bracket 1 and is fixedly connected to a driving rotating rod 24 at its end. A driving double-groove roller 25 for cooperation is fixedly sleeved on the outer side of the driving rotating rod 24. The end of the output end of the electric telescopic rod 22 is fixedly connected to a pushing slider 26. A driven rotating rod 27 is rotatably inserted on the pushing slider 26. The driven rotating rod 27 movably penetrates through the mounting bracket 1 and a driven double-groove roller 28 is fixedly sleeved on its outer side. A polishing abrasive belt 29 for cooperation is drivingly sleeved on the outer sides of the driven double-groove roller 28 and the driving double-groove roller 25. There are two polishing abrasive belts 29. A sliding through groove 11 is penetrated through the top end of the mounting bracket 1. The driven rotating rod 27 is movably inserted in the sliding through groove 11. The setting of the sliding through groove 11 provides a guarantee for the movement adjustment and normal rotation of the driven rotating rod 27; The output end of the multi-stage electric push rod 23 slidably penetrates through the mounting bracket 1 and a shielding outer cover 210 for cooperation with the polishing abrasive belt 29 is fixedly sleeved at its end. The shielding outer cover 210 is slidably connected to the mounting bracket 1. A polishing through groove 211 for cooperation with the polishing abrasive belt 29 is penetrated through one end of the shielding outer cover 210 away from the multi-stage electric push rod 23. A guiding sleeve 212 is fixedly inserted on the mounting bracket 1. A guiding sliding rod 213 is fixedly inserted on the shielding outer cover 210. The guiding sliding rod 213 can be slidably inserted in the guiding sleeve 212. The cooperation of the guiding sleeve 212 and the guiding sliding rod 213 can guarantee the stable movement of the shielding outer cover 210. An installation through hole 12 is penetrated through the upper end of the mounting bracket 1. The guiding sleeve 212 is fixedly inserted in the installation through hole 12. An installation through hole 214 is penetrated through the shielding outer cover 210. The guiding sliding rod 213 is fixedly inserted in the installation through hole 214. The setting of the installation through hole 12 and the installation through hole 214 provides a guarantee for the stable insertion of the guiding sleeve 212 and the guiding sliding rod 213.

[0025] By adopting the above technical solution, during use, the polishing motor 21 can drive the driving rotating rod 24 to rotate, which can further drive the driving double-groove roller 25 to rotate. Further, in cooperation with the use of the driven rotating rod 27 and the driven double-groove roller 28, the two polishing abrasive belts 29 can be driven to rotate synchronously. At the same time, the manipulator can clamp the corresponding aero-engine blade and pass through the polishing through groove 211 for polishing by the corresponding polishing abrasive belt 29. During subsequent use, the multi-stage electric push rod 23 can be started, so that the shielding outer cover 210 can be driven to move away from the polishing motor 21, and then the polishing through groove 211 can be driven to move synchronously. When the polishing through groove 211 moves to the position corresponding to the other polishing abrasive belt 29, the multi-stage electric push rod 23 is closed, so that the other polishing abrasive belt 29 can be used to continuously carry out the polishing operation of the aero-engine blade. In addition, after the processing device is used up, the multi-stage electric push rod 23 can be started again, so that the shielding outer cover 210 can be driven to move away from the polishing motor 21 again until both polishing abrasive belts 29 move to the outside of the shielding outer cover 210. Then, the electric telescopic rod 22 is started, so that the pushing slider 26 can be driven to move towards the driving double-groove roller 25, and then the driven double-groove roller 28 can be driven to move towards the driving double-groove roller 25 through the driven rotating rod 27, so that the polishing abrasive belt 29 can be loosened. Subsequently, the electric telescopic rod 22 is paused and the two polishing abrasive belts 29 to be replaced are removed. Then, the two new polishing abrasive belts 29 are sleeved on the driving double-groove roller 25 and the driven double-groove roller 28, and the driven double-groove roller 28 is reset, so that the two replaced polishing abrasive belts 29 can be tensioned. Then, the shielding outer cover 210 is reset.

[0026] The heat dissipation mechanism 3 includes a support chassis 31 which is fixedly installed at the bottom end of the installation bracket 1, and a heat dissipation frame body 32 is fixedly installed at the top end of the support chassis 31. At the upper end of one side of the heat dissipation frame body 32, symmetrically arranged first L-shaped ducts 33 are communicated. The end of the first L-shaped duct 33 is fixedly connected with a connecting hose 34, and the end of the connecting hose 34 is fixedly connected with a second L-shaped duct 35. The second L-shaped duct 35 is fixedly installed at one end of the shielding outer cover 210 close to the polishing through groove 211. The second L-shaped duct 35 is communicated with the shielding outer cover 210. An air inlet through hole 215 which is used in cooperation with the polishing abrasive belt 29 and the second L-shaped duct 35 is penetrated and opened at the bottom end of the shielding outer cover 210, and the air inlet through hole 215 is of a symmetric structure. A heat dissipation cylinder body 36 is communicated at the bottom end of the heat dissipation frame body 32, and a grid insertion plate 37 is integrally formed in the inner cavity of the heat dissipation cylinder body 36. A fixing through hole 317 is penetrated and opened in the middle of the top end of the support chassis 31, and the heat dissipation cylinder body 36 is fixedly inserted into the fixing through hole 317. The arrangement of the fixing through hole 317 provides a guarantee for the stable insertion of the heat dissipation cylinder body 36. A heat dissipation fan 38 is fixedly inserted in the middle of the grid insertion plate 37, and an intercepting filter disc 39 which is used in cooperation with the heat dissipation fan 38 is fixedly inserted at the top end of the heat dissipation cylinder body 36. An air outlet through hole 310 which is used in cooperation with the heat dissipation fan 38 is penetrated and opened at the bottom end of the heat dissipation cylinder body 36, and the air outlet through hole 310 is distributed in an array; A clamping through groove 311 is penetrated and opened at the side of the heat dissipation frame body 32 far away from the first L-shaped duct 33, and three clamping insertion frames 312 are detachably inserted in the clamping through groove 311. Symmetrically distributed electric cylinder bodies 313 are fixedly installed on the inner wall of the clamping insertion frame 312, and electric cylinder sliders 314 are slidably arranged on the electric cylinder bodies 313. A storage battery which is used in cooperation with the electric cylinder bodies 313 and the electric cylinder sliders 314 is arranged in the clamping insertion frame 312, so as to be able to provide power for the electric cylinder bodies 313 and the electric cylinder sliders 314. This is the prior art and will not be elaborated here. The bottom ends of the two electric cylinder sliders 314 are fixedly connected with a sliding cross plate 315, and the sliding cross plate 315 is in sliding fit with the bottom end of the clamping insertion frame 312. The top end of the sliding cross plate 315 is fixedly connected with an intercepting filter bag 316, and the other end of the intercepting filter bag 316 is fixedly connected with the inner wall of the clamping insertion frame 312. The side of the intercepting filter bag 316 can be in movable contact with the clamping insertion frame 312. The structure of the intercepting filter bag 316 is the same as that of the filter bag of the existing vacuum cleaner, which is the prior art and will not be elaborated here.

[0027] By adopting the above technical solution, during use, the cooling fan 38 can continuously suck the air in the cooling frame 32 into the cooling cylinder 36 and discharge it, so that the outside cold air can be continuously sucked into the shielding cover 210 through the first L-shaped conduit 33, the connecting hose 34 and the second L-shaped conduit 35 via the polishing through slots 211 and the air inlet through holes 215. Furthermore, the used polishing abrasive belt 29 can be effectively cooled, thereby avoiding the phenomenon of over-high local temperature of the polishing abrasive belt 29, further ensuring the normal progress of the polishing operation of the aero-engine blades. At the same time, the heated air will drive the polishing debris of the aero-engine blades into the inner cavity of the cooling frame 32. Then, the uppermost intercepting filter bag 316 can intercept and store the polishing debris of the aero-engine blades, and the filtered heated air will be discharged again. When the uppermost intercepting filter bag 316 has been used for a period of time, the corresponding electric cylinder body 313 and the electric cylinder body 313 at its lower end will be started synchronously. Thus, the sliding cross plate 315 corresponding to the used intercepting filter bag 316 can be driven by the corresponding electric cylinder slider 314 to move towards the side close to the clamping through slot 311, and the sliding cross plate 315 corresponding to the unused intercepting filter bag 316 can be driven by the corresponding electric cylinder slider 314 to move away from the clamping through slot 311. Furthermore, the used intercepting filter bag 316 can be folded and stored, and the next unused intercepting filter bag 316 can be unfolded. Subsequently, the retracting and deploying operations of the intercepting filter bag 316 can be carried out according to the above steps.

[0028] The limiting mechanism 4 includes a side connecting cross plate 41, which is fixedly connected to the cooling frame 32. A sliding guide hole 42 is penetrated through the middle of the side connecting cross plate 41. A Z-shaped limiting rod 43 that cooperates with the clamping insertion frame 312 is slidably inserted into the sliding guide hole 42. A limiting collar 44 is fixedly sleeved at the top of the Z-shaped limiting rod 43. A limiting spring 45 is fixedly installed at the bottom of the limiting collar 44. The end of the limiting spring 45 is fixedly connected to the side connecting cross plate 41. Anti-slip grooves 46 that cooperate with each other are formed on the outer wall of the limiting collar 44, and the anti-slip grooves 46 are distributed in an array. The setting of the anti-slip grooves 46 can increase the friction and facilitate the operation.

[0029] By adopting the above technical solution, during use, after the processing device is used up, the limiting collar 44 needs to be pulled up, so that the Z-shaped limiting rod 43 can be driven to move upward, and then the limiting spring 45 can be stretched. When the bottom end of the Z-shaped limiting rod 43 moves to the upper side of the top of the clamping through slot 311, stop pulling the limiting collar 44. At this time, the Z-shaped limiting rod 43 will be completely separated from the three clamping insertion frames 312. Then, the three clamping insertion frames 312 are pulled out in sequence and cleaned. After the cleaning is completed, the reverse operation can be carried out according to the above steps to reset and fix them.

[0030] Working principle: During use, install the mounting bracket 1 in a suitable position, and then start the polishing motor 21 and the cooling fan 38. Thus, the driving rotating rod 24 can be driven to rotate by the polishing motor 21, and then the driving double-groove roller 25 can be driven to rotate. Further, the use of the driven rotating rod 27 and the driven double-groove roller 28 can be coordinated to drive the two polishing abrasive belts 29 to rotate synchronously. At the same time, the manipulator can clamp the corresponding aeroengine blade and pass through the polishing through groove 211 for polishing by the corresponding polishing abrasive belt 29. And during subsequent use, the multi-stage electric push rod 23 can be started, so that the shielding outer cover 210 can be driven to move to the side away from the polishing motor 21, and then the polishing through groove 211 can be driven to move synchronously. And when the polishing through groove 211 moves to the position corresponding to the other polishing abrasive belt 29, the multi-stage electric push rod 23 is closed, so that the other polishing abrasive belt 29 can be used to continuously carry out the polishing operation of the aeroengine blade; During this period, the cooling fan 38 can continuously suck the air in the cooling frame 32 into the cooling cylinder 36 and discharge it. Thus, the outside cold air can be continuously sucked into the shielding outer cover 210 through the polishing through groove 211 and the air inlet through hole 215 by the first L-shaped conduit 33, the connecting hose 34 and the second L-shaped conduit 35. Further, the used polishing abrasive belt 29 can be effectively cooled, and further, the phenomenon of excessive local temperature of the polishing abrasive belt 29 can be avoided, further ensuring the normal development of the aeroengine blade polishing operation. At the same time, the heat-absorbed air will drive the aeroengine blade polishing debris into the inner cavity of the cooling frame 32. Then, the uppermost intercepting filter bag 316 can intercept and store the aeroengine blade polishing debris, and the filtered heat-absorbed air will be discharged again. When the uppermost intercepting filter bag 316 is used for a period of time, the corresponding electric cylinder body 313 and the electric cylinder body 313 at its lower end will be started synchronously. Thus, the sliding cross plate 315 corresponding to the used intercepting filter bag 316 can be driven to move to the side close to the clamping through groove 311 by the corresponding electric cylinder slider 314, and the sliding cross plate 315 corresponding to the unused intercepting filter bag 316 can be driven to move to the side away from the clamping through groove 311 by the corresponding electric cylinder slider 314. Further, the used intercepting filter bag 316 can be folded and stored and the next unused intercepting filter bag 316 can be unfolded. Then, the retracting and deploying operation of the intercepting filter bag 316 can be carried out according to the above steps; In addition, after the processing device is used up, the multi-stage electric push rod 23 can be restarted, so that the shielding outer cover 210 can be driven to move away from the polishing motor 21 again until both polishing abrasive belts 29 move to the outside of the shielding outer cover 210. Then, the electric telescopic rod 22 is started, so that the pushing slider 26 can be driven to move towards the side close to the driving double-groove roller 25, and then the driven double-groove roller 28 can be driven to move towards the side close to the driving double-groove roller 25 through the driven rotating rod 27, so that the polishing abrasive belt 29 can be loosened. Subsequently, the electric telescopic rod 22 is paused and the two polishing abrasive belts 29 to be replaced are removed. Then, the two new polishing abrasive belts 29 are sleeved on the driving double-groove roller 25 and the driven double-groove roller 28, and the driven double-groove roller 28 is reset, so that the two replaced polishing abrasive belts 29 can be tensioned. After that, the shielding outer cover 210 is reset. And after the processing device is used up, the limit collar 44 needs to be pulled up, so that the Z-shaped limit rod 43 can be driven to move upward, and then the limit spring 45 can be stretched. When the bottom end of the Z-shaped limit rod 43 moves to the upper side of the top end of the clamping through groove 311, stop pulling the limit collar 44. At this time, the Z-shaped limit rod 43 will be completely separated from the three clamping plug frames 312. Then, the three clamping plug frames 312 are sequentially pulled out and cleaned. And after the cleaning is completed, they can be reset and fixed according to the above steps in the reverse operation.
