[0016] Compared with the prior art, the present application has the following advantages: (1) The present application injects external air into the air inlet pipe through the fan, and the polishing cloth is attached to the polishing surface of the filter shell through the airflow. Then, the polishing cloth is driven to rotate by the motor. Therefore, the polishing cloth is always attached to the surface of the filter shell during the rotation of the polishing cloth due to the airflow. The surface of the filter shell, which is concave and small in volume, can be quickly polished without adjusting the filter shell and the polishing equipment during the polishing process, thereby preventing polishing omissions and inconsistent polishing thicknesses from affecting the overall polishing quality.

[0017] (2) When polishing the concave surface of the filter shell, the filter shell is arranged between or on the two positioning plates.

The filter shell can be fixed in a targeted manner without affecting the polishing operation of the filter shell when facing different polishing surfaces.

[0018] (3) The filter shell is attached to the polishing cloth through the stable thrust provided by the downward spring. This can prevent the polishing cloth from stretching beyond the limit and causing severe deformation and cavities due to excessive pressure when the polishing cloth contacts the filter shell, thereby affecting the polishing effect.

[0019] (4) The present application uses a polishing cloth with a smaller particle size for polishing first, and then uses a polishing cloth with a larger particle size for polishing. This can prevent the use of a polishing cloth with a larger particle size to polish the burrs and knife marks on the surface of the filter shell, which can cause severe wear of the polishing cloth and poor polishing effect.

[0020] (5) When polishing the concave surface of the filter shell, the polishing strip is located at the bending part of the fin root of the filter shell. When the air outlet pipe is driven to rotate by the motor, the polishing strip is simultaneously driven to rotate around the filter shell while rubbing at the bending part of the fin root of the filter shell. In this way, the polishing of the bending part of the fin root of the filter shell is completed, further reducing the dead angle of the filter shell polishing and preventing polishing omissions, thereby improving the polishing quality of the filter shell.

[0021] (6) The scheme can drive the cutting blade to move around the filter shell synchronously when the motor drives the fixed branch arm and the movable branch arm to rotate, and the burrs at the bent part of the filter shell fin can be removed when the cutting blade moves around the bent part of the filter shell fin, so that the polishing efficiency and quality of the bent part of the filter shell fin are improved, and the polishing bar is prevented from being lifted and suspended due to the long burrs, so that the polishing dead angle is generated, the polishing quality is affected, and more time is consumed for polishing and removing the burrs.

[0029] The chute 309 is located between the two rotating shafts 317, the two polishing cloths 205 have different surface particle sizes, the polishing cloth 205 with smaller particle size is used first for polishing, and then the polishing cloth 205 with larger particle size is used for polishing, so that the burrs and knife marks on the surface of the filter shell are prevented from being too large and too deep, and the polishing cloth 205 is prevented from being seriously worn and the polishing effect is prevented from being poor when the polishing cloth 205 with larger particle size is directly used for polishing. The connecting guide frame 314 is inserted into the inside of the extension support plate 315, the bottom end of the connecting guide frame 314 is fixedly connected with the upper surface of the downward pressing separation block 313, the top end of the support frame 311 is rotationally connected with the support wheel 312, the frictional resistance and wear of the downward pressing separation block 313 can be reduced through the support wheel 312, and the cross section shape of the downward pressing separation block 313 is isosceles trapezoidal.

[0030] By adopting the above technical scheme, before polishing the filter shell, the filter shell is placed between the two positioning plates 306, then the worker holds and rotates the rotating handle 301 to drive the screw rod one 307 and the screw rod two 308 to rotate, because the screw thread directions of the screw rod one 307 and the screw rod two 308 are opposite, so the two moving plates 305 can be driven to move away from each other or move close to each other during the rotation of the screw rod one 307 and the screw rod two 308, and the filter shell is fixed.

[0031] When polishing the inner concave surface of the filter shell, the filter shell is arranged between the two positioning plates 306, the inner concave surface faces away from the screw rod one 307 and the screw rod two 308, then the two positioning plates 306 are clamped on the upper surface and the lower surface of the filter shell respectively through the cooperation of the screw rod one 307 and the screw rod two 308, so that the filter shell is fixed; when polishing the outer convex surface of the filter shell, the filter shell is sleeved on the two positioning plates 306, the outer convex surface faces away from the screw rod one 307 and the screw rod two 308, then the two positioning plates 306 are abutted on the inner upper surface and the inner lower surface of the filter shell respectively through the cooperation of the screw rod one 307 and the screw rod two 308, so that the filter shell is fixed, and the filter shell can be fixed specifically without affecting the polishing operation of the filter shell when facing different polishing surfaces.

[0032] In the polishing of the filter shell, after the fixing of the filter is completed, the supporting stand 302 is rotated to make the filter shell face the polishing cloth 205 with smaller granularity, then the rotation shaft 317 on the side away from the polishing cloth 205 with smaller granularity is rotated to make the pressing separation block 313 corresponding to the rotation shaft 317 rotate above the sliding groove 309, and the pushing force generated by the rebound of the pressing spring 318 makes the pressing separation block 313 press between the two supporting wheels 312, the two supporting wheels 312 and the two inclined surfaces of the pressing separation block 313 are extruded, so as to push the sliding block 310 to move, so that the filter shell is attached to the surface of the polishing cloth 205 with smaller granularity, and the stable pushing force provided by the pressing spring 318 makes the filter shell attach to the polishing cloth 205, which can prevent the polishing cloth 205 from being deformed seriously to generate cavities and affect the polishing effect when the polishing cloth 205 contacts the filter shell with too much pressure, then the fan 203 is started to make the polishing cloth 205 attach to the filter shell, and the motor 204 drives the polishing cloth 205 to rotate, so that the filter shell is pre-polished by the polishing cloth 205 with smaller granularity. After the pre-polishing operation of the filter shell is completed, the supporting stand 302 is rotated to make the filter shell face the polishing cloth 205 with larger granularity, then the rotation shaft 317 on the side away from the polishing cloth 205 with larger granularity is rotated to make the pressing separation block 313 corresponding to the rotation shaft 317 rotate above the sliding groove 309, and the pushing force generated by the rebound of the pressing spring 318 makes the pressing separation block 313 press between the two supporting wheels 312, the two supporting wheels 312 and the two inclined surfaces of the pressing separation block 313 are extruded, so as to push the sliding block 310 to move, so that the filter shell is attached to the surface of the polishing cloth 205 with larger granularity, then the fan 203 is started to make the polishing cloth 205 attach to the filter shell, and the motor 204 drives the polishing cloth 205 to rotate, so that the filter shell is polished by the polishing cloth 205 with larger granularity, and through the above operation, the polishing cloth 205 with smaller granularity is used for polishing first, and then the polishing cloth 205 with larger granularity is used for polishing, which can prevent the burrs, knife marks and the like on the surface of the filter shell from being too large and too deep to directly use the polishing cloth 205 with larger granularity for polishing to cause serious wear of the polishing cloth 205 and poor polishing effect.

[0033] As Figure 7 and Figure 8As shown, the surface of the air outlet pipe 212 is fixedly sleeved with a fixed ring 404, the outer circular surface of the fixed ring 404 is fixedly connected with a first stand 401, the transverse arm end of the first stand 401 is fixedly connected with a horizontal shaft 405, the surface of the horizontal shaft 405 is fixedly connected with a fixed branch arm 417, the upper end of the fixed branch arm 417 is rotatably connected with a movable branch arm 407, the movable branch arm 407 and the lower end of the fixed branch arm 417 are fixedly connected with a polishing strip 402, the polishing strip 402 is polished while rotating around the filter shell, and the polishing strip 402 is rubbed at the root bending part of the filter shell fin, so that the root bending part of the filter shell fin is polished, the surfaces of the movable branch arm 407 and the fixed branch arm 417 are fixedly connected with a support vertical plate 406, the two support vertical plates 406 are fixedly connected with a tension spring 409, the tension spring 409 provides tension to separate the movable branch arm 407 and the fixed branch arm 417 from each other while straightening the polishing strip 402, so that the polishing strip 402 is attached to the root bending part of the filter shell fin, and the surface of the end of the horizontal shaft 405 away from the first stand 401 is fixedly connected with a supporting block 408, the supporting block 408 can prevent the tension spring 409 from being skewed and stuck during stretching, thereby affecting the normal use of the tension spring 409.

[0034] Wherein, the lower end of the fixed branch arm 417 is fixedly connected with a drooping stand 410, the bottom end of the drooping stand 410 is rotatably connected with a support arm 403, the end of the support arm 403 away from the drooping stand 410 is slidably sleeved with a pushing arm 415, the end of the pushing arm 415 away from the support arm 403 is fixedly connected with a corner stand 414, the two ends of the corner stand 414 are fixedly connected with a cutting blade 413, the cutting blade 413 moves around the root bending part of the filter shell fin, and the burrs of the root bending part of the filter shell fin are cut off, the surfaces of the support arm 403 and the pushing arm 415 are fixedly sleeved with a support disc 416, the two support discs 416 are fixedly connected with a pressure spring 412, the pressure spring 412 provides an elastic force to push the cutting blade 413 to always adhere to the root bending part of the filter shell fin when the cutting blade 413 moves around the filter shell, the inside of the lower end of the drooping stand 410 is slidably connected with a limiting frame 411 matched with the support arm 403, and the limiting frame 411 is sleeved at the contact part of the support arm 403 and the drooping stand 410 to limit the rotation of the support arm 403.

[0035] By adopting the above technical scheme, when polishing the inner concave surface of the filter shell, the polishing strip 402 is located at the bending part of the fin root of the filter shell, and the two supporting vertical plates 406 are made close to each other by the tension provided by the tension spring 409, that is, the movable branch arm 407 and the fixed branch arm 417 are separated from each other while the polishing strip 402 is straightened, so that the polishing strip 402 is attached to the bending part of the fin root of the filter shell, then the first vertical stand 401 is rotated synchronously when the motor 204 drives the air outlet pipe 212 to rotate, so that the polishing strip 402 rotates around the filter shell while the polishing strip 402 rubs at the bending part of the fin root of the filter shell, thereby completing the polishing of the bending part of the fin root of the filter shell, further reducing the dead angle of the filter shell polishing, and improving the polishing quality of the filter shell.

[0036] Before polishing the bending part of the fin root of the filter shell, the supporting arm 403 is rotated to drive the cutting blade 413 to be located at the bending part of the fin root of the filter shell, and the limiting frame 411 is moved downward to be sleeved on the contact part of the supporting arm 403 and the drooping stand 410, thereby limiting the rotation of the supporting arm 403. The cutting blade 413 is made of a thin steel sheet, the lower end of which is ground into a blade edge and attached to the bending part of the fin root of the filter shell. Therefore, when the motor 204 drives the fixed branch arm 417 and the movable branch arm 407 to rotate, the cutting blade 413 is moved around the filter shell synchronously, and the cutting blade 413 is always attached to the bending part of the fin root of the filter shell when it moves around the filter shell by the elastic force of the pressure spring 412. Therefore, when the cutting blade 413 moves around the bending part of the fin root of the filter shell, the burrs on the bending part of the fin root of the filter shell are removed, and the polishing strip 402 is not needed to polish the burrs for a long time, thereby improving the polishing efficiency and quality of the bending part of the fin root of the filter shell, preventing the burrs from being too long to lift the polishing strip 402 and causing a polishing dead angle, affecting the polishing quality, and consuming more time for polishing.

[0037] Method for use: first, the filter shell is arranged between or on the two positioning plates 306; Then, the two positioning plates 306 are driven by the screw rod one 307 and the screw rod two 308 to be clamped on the upper surface and the lower surface of the filter shell or to abut against the inner upper surface and the inner lower surface of the filter shell, respectively, so as to fix the filter shell; Then, the filter shell is directed towards the polishing cloth 205 with smaller granularity; Then, the shaft 317 away from the polishing cloth 205 with smaller granularity is rotated, so that the pressing separation block 313 is pressed between the two supporting wheels 312; Then, the fan 203 is started to attach the polishing cloth 205 to the filter shell; Subsequently, the motor 204 drives the polishing cloth 205 to rotate, and the filter housing is pre-polished by the polishing cloth 205 with small granularity; Subsequently, the filter housing is moved towards the polishing cloth 205 with large granularity; Then, the rotation shaft 317 on the side away from the polishing cloth 205 with small granularity is rotated, so that the pressing separation block 313 is pressed between the two supporting wheels 312; Then, the fan 203 is started to make the polishing cloth 205 adhere to the filter housing; Finally, the motor 204 drives the polishing cloth 205 to rotate, and the filter housing is polished by the polishing cloth 205 with large granularity; When the inner concave surface of the filter housing is polished, the polishing strip 402 is located at the bending part of the fin root of the filter housing; Then, the cutting blade 413 is rotated to the bending part of the fin root of the filter housing; Then, the limiting frame 411 is sleeved on the contact part of the supporting arm 403 and the drooping frame 410, and the rotation of the cutting blade 413 is limited; Subsequently, the motor 204 drives the cutting blade 413 to cut the burrs on the bending part of the fin root of the filter housing; At the same time, the motor 204 drives the polishing strip 402 to rub around the bending part of the fin root of the filter housing, and the bending part of the fin root of the filter housing is polished.
