One end of the rack 331 close to the chuck 2 is fixedly connected with a feeding pipe 333. A spring 334 is fixedly connected to the inner wall of the feeding pipe 333.

The support ring is used to position and support the second liquid discharge pipe 38 and the nozzle 39, so that the nozzle 39 is supported directly above the turned part 5; The above scheme is adopted: through the cooling and polishing switching mechanism 3, the gear disc 32 can be controlled to rotate during the turning process of the turned part 5, so as to move the switching member 33 connected with the spray pipe 34, so as to move the spray pipe 34 to the inner core of the turned part 5, and the pump 37 draws cooling liquid from the liquid storage tank 311, so that part of the cooling liquid drawn is atomized and sprayed to the outside of the turned part 5 by the second liquid discharge pipe 38 and the nozzle 39, and the other part of the cooling liquid is sprayed to the inner core of the turned part 5 by the spray pipe 34, so as to realize the simultaneous cooling of the inside and outside of the turned part 5, improve the cooling effect of the turned part 5, and increase the service life of the device; By setting up the cooling and polishing switching mechanism 3, it is also possible to control the rotation of the toothed disc 32 when the turning of the turned part 5 is completed, and to link the switching member 33 fixed with the polishing rod 35 to move, so as to cause the polishing rod 35 to move and penetrate into the inner core of the turned part 5. In this way, while polishing and grinding the inner core of the turned part 5, the metal debris retained in the inner core of the turned part 5 is pushed out of the turned part 5, which can increase the polishing function of the inner core of the turned part 5 and improve the cleaning efficiency of the inner core of the turned part 5.

[0016] Please refer to Figure 2 and Figure 3As shown in the figure, the cleaning mechanism 4 includes a second motor 41 fixedly installed on the outer surface of the processing seat 6. The output end of the second motor 41 is fixedly connected to a rotating shaft 44. A gear 42 is fixedly connected to the outer surface of the rotating shaft 44, and a fan blade 45 is fixedly connected to the outer surface of the rotating shaft 44. A toothed ring 43 is fixedly connected to the outer surface of the chuck 2, and the toothed ring 43 is meshed and matched with the gear 42; The cleaning mechanism 4 further includes a collecting air duct 46 fixedly connected to the outer surface of the processing seat 6. One end of the collecting air duct 46 away from the gear 42 communicates with a material guiding hopper 47. A filter screen 48 is fixedly connected to the bottom end of the collecting air duct 46. A protective cover 7 is slidably connected to the outer surface of the processing seat 6; Supplementary description: The collecting air duct 46 is in a T shape. One end of the collecting air duct 46 close to the gear 42 wraps around the outside of the fan blade 45. One end of the collecting air duct 46 located below the material guiding hopper 47 is used to connect to the storage tank for recycling the cooling liquid; The protective cover 7 wraps around the outside of the material guiding hopper 47 and the turning part 5. A transparent glass is installed on the protective cover 7. The protective cover 7 is used to prevent the metal chips generated during the processing of the turning part 5 from spreading outwards; Magnetic blocks are fixedly installed on both sides of the top surface of the filter screen 48, and the magnetic blocks are used to magnetically attract metal chips; Adopting the above solution: Through the set cleaning mechanism 4, the continuous rotation of the rotating shaft 44 can be utilized to make the gear 42 and the fan blade 45 rotate accordingly. The rotation of the gear 42 drives the rotation of the toothed ring 43, so that the chuck 2 and the turning part 5 rotate accordingly, facilitating the turning of the turning part 5. The rotation of the fan blade 45 cooperates with the collecting air duct 46 to gather the metal chips blocked in the protective cover 7, preventing the metal chips from splashing outwards and causing impact damage to the operator, and facilitating the centralized treatment of the metal chips by the personnel; Through the set cleaning mechanism 4, the material guiding hopper 47 can also be utilized to guide and drain the cooling liquid sprayed towards the turning part 5, so that the cooling liquid and the metal chips move towards the filter screen 48. While the filter screen 48 centrally bears and collects the metal chips, the cooling liquid passes through the filter screen 48 and is centrally recycled, which is beneficial to the recycling of the cooling liquid and saves the use cost of the device.

[0017] It should also be supplemented and explained that: one switching member 33 is used to carry and install the spraying pipe 34, and the other switching member 33 is used to carry and install the polishing rod 35. The two groups of switching members 33 move in opposite directions due to the rotation of the toothed disc 32. That is, when one guide rod 336 moves along the guide frame 332 towards the turning part 5, the spring 334 is pulled by the push rod 335 and is in an extended state. The guide frame 332 aligns the corresponding installation object with the inner core of the turning part 5. On the contrary, the other guide rod 336 moves along the guide frame 332 towards the liquid storage tank 311, and the corresponding spring 334 resets and contracts, so that the guide frame 332 avoids the corresponding installation object, prompting the object aligned with the inner core of the turning part 5 to smoothly enter the inner core of the turning part 5; Working principle and usage process of the present invention: Preliminary preparation: The staff first fills the liquid storage tank 311 with the cooling liquid, and then screws and installs the liquid storage tank 311 filled with the cooling liquid onto the main shaft body 1; During the turning process of the turning part 5, the operator operates the control panel to start the second motor 41. Since the output end of the second motor 41 is fixedly connected to the rotating shaft 44, the outer surface of the rotating shaft 44 is fixedly connected with the gear 42, the outer surface of the rotating shaft 44 is fixedly connected with the fan blade 45, and the outer surface of the chuck 2 is fixedly connected with the toothed ring 43. The toothed ring 43 is meshed and matched with the gear 42, so that the toothed ring 43 and the fan blade 45 rotate following the rotation of the rotating shaft 44. The rotation of the toothed ring 43 will drive the chuck 2 and the turning part 5 to rotate together, facilitating the turning of the turning part 5 in cooperation with the tool. The rotation of the fan blade 45 will gather the metal chips blocked in the protective cover 7 through the air collecting pipe 46 and the protective cover 7; Immediately afterwards, the operator operates the control panel to start the first motor 31. Since the output end of the first motor 31 is fixedly connected to the toothed disc 32, two groups of switching members 33 are symmetrically arranged between the toothed disc 32 and the main shaft body 1, and the rack 331 is meshed and matched with the toothed disc 32. One end of the rack 331 close to the chuck 2 is fixedly connected to the supply pipe 333. The inner wall of the supply pipe 333 is fixedly connected with the spring 334. The inner wall of the supply pipe 333 is slidably connected with the push rod 335. The push rod 335 abuts against the spring 334. The outer surface of the push rod 335 is fixedly connected with the guide rod 336. One end of the push rod 335 away from the supply pipe 333 is fixedly connected to the bearing seat 337. The outer surface of one bearing seat 337 is fixedly installed with the polishing rod 35, and the other bearing seat 337 is communicated with the spraying pipe 34. The spraying pipe 34 is communicated with the first drain pipe 36. The bearing seat 337 communicated with the spraying pipe 34 moves towards the turning part 5 with the clockwise rotation of the toothed disc 32 until the spraying pipe 34 penetrates into the inner core of the turning part 5. At this time, the first motor 31 is controlled to stop; Then, the personnel operate the control panel to start the pump 37. Since the pump 37 is connected to the first liquid discharge pipe 36, the end of the pump 37 close to the liquid storage tank 311 is connected to the liquid extraction pipe 310, and the top of the pump 37 is connected to the second liquid discharge pipe 38. The end of the second liquid discharge pipe 38 close to the turned part 5 is connected to the nozzle 39, so that the pump 37 is prompted to extract cooling liquid from the liquid storage tank 311 through the liquid extraction pipe 310, and a part of the extracted cooling liquid is sprayed to the inner core of the turned part 5 through the spray pipe 34, while the other part of the cooling liquid is sprayed to the outside of the turned part 5 through the second liquid discharge pipe 38 and the nozzle 39, so that the inside and outside of the turned part 5 are cooled simultaneously, thereby improving the cooling effect of the turned part 5. After the turning of the turned part 5 is completed, the above working process is reversed to control the first motor 31 to start and make the gear disc 32 rotate counterclockwise. At this time, the bearing seat 337 connected to the spray pipe 34 moves toward the liquid storage tank 311 until the corresponding guide rod 336 slides away from the guide frame 332. At this time, the bearing seat 337 is pulled by the spring 334 and avoids the polishing rod 35 opposite to it. The bearing seat 337 with the polishing rod 35 fixed thereon moves toward the turned part 5, so that the polishing rod 35 moves and penetrates the inner core of the turned part 5, thereby polishing and grinding the inner core of the turned part 5, and at the same time, the metal debris retained in the inner core of the turned part 5 is pushed out of the turned part 5; Finally, the guide hopper 47 is used to guide and drain the cooling liquid sprayed toward the turned part 5, so that the cooling liquid and metal chips move toward the filter 48. The filter 48 collects the metal chips and allows the cooling liquid to pass through the filter 48 for centralized recovery.

[0018] Summary: The cooling and polishing switching mechanism 3 is set to control the clockwise and counterclockwise rotation of the toothed disc 32, and freely control the spraying pipe 34 and the polishing rod 35 to be inserted into the inner core of the turned part 5. The spraying pipe 34 is inserted into the inner core of the turned part 5, and the pump 37, the first liquid discharge pipe 36 and the second liquid discharge pipe 38 are coordinated to spray to the inside and outside of the turned part 5, so as to achieve simultaneous cooling of the inside and outside of the turned part 5, improve the cooling effect of the turned part 5, and increase the service life of the device. The polishing rod 35 is inserted into the inner core of the turned part 5, and while polishing and grinding the inner core of the turned part 5, the metal debris retained in the inner core of the turned part 5 is pushed out of the turned part 5, which can increase the polishing function of the inner core of the turned part 5 and improve the cleaning efficiency of the inner core of the turned part 5; By means of the cleaning mechanism 4, the continuous rotation of the rotating shaft 44 can be utilized to link the gear 42 and the fan blade 45 to rotate accordingly. The rotation of the gear 42 links the rotation of the gear ring 43. The rotation of the gear 42 facilitates the turning of the turned part 5. The rotation of the fan blade 45 prevents metal debris from splashing outward and causing damage to the operator, and facilitates the centralized treatment of the metal debris by the operator. The guide hopper 47 is used to guide and drain the cooling liquid sprayed toward the turned part 5, so that the cooling liquid and the metal debris move toward the filter 48. While the filter 48 collects the metal debris in a centralized manner, the cooling liquid is recovered through the filter 48 in a centralized manner, which is beneficial to the recycling of the cooling liquid and saves the cost of using the device.
