[0015] The beneficial effects of the present invention are as follows:

[0016] 1. The chip rolling device of a CNC lathe for mechanical processing described in the present invention, the servo motor drives the rectangular frame and the boss on the screw rod to start moving, and the boss and the rotating column cooperate to slide and eject the required tool. The movement of the tool depends on the slider in the slide groove, and when the tool is not pushed by the boss, it will always remain in the initial position under the influence of the elastic part. Through the replacement mechanism designed above, all the tools required for processing can be installed in the tool holder in advance, and there is no need to stop the machine during processing. Automatic tool replacement can be achieved through CNC programming, which greatly improves the processing efficiency and reduces the occurrence of continuous calibration due to the need for continuous replacement.

[0017] 2. The chip rolling device for a CNC lathe used for mechanical processing described in the present invention continuously squeezes the first elastic block at the bottom of the connecting plate through the top block when moving, so that the gas of the first elastic block is sprayed to the tool through the outlet pipe, thereby blowing off the iron chips and cutting fluid on the tool. Iron chips remaining on the tool are very likely to cause uneven subsequent cutting, rough connection surface and inaccurate size, thereby shortening the service life of the tool. At the same time, the corrosive substances contained in the cutting fluid will react with the tool material, causing corrosion and rust of the tool. The top block squeezes the liquid storage box, and after the liquid storage box is squeezed, the maintenance liquid inside will enter the fixed tube and the nozzle through the infusion tube and spray out. The sprayed gas will blow the sprayed maintenance liquid to the surroundings, thereby increasing the area of ​​spraying of the maintenance liquid, thereby completing the maintenance of the tool. Provide the service life of the tool.

[0018] 3. The chip rolling device for a CNC lathe used for mechanical processing described in the present invention allows the gas in the second elastic frame to enter the fixed frame through the conduit, and uses the gas to push the sliding frame and the detector in the fixed frame to slide in the direction away from the rectangular frame. The detector will continuously detect the surface of the tool while moving. When a worn tool is detected, the electromagnet increases the amount of electricity, so that the slide bar and the sleeve plate move away from the electromagnet again. At this time, the sleeve plate squeezes the arc block, so that the paint in the arc block is sprayed on the tool through the spray tube for marking, thereby facilitating the subsequent staff to replace the damaged tool in time, avoiding the impact of tool wear on the processing accuracy of the parts.

[0019] 4. The chip rolling device for a CNC lathe used for mechanical processing described in the present invention installs an inclined protective cloth so that the sprayed lubricating oil will be guided into the guide hole after dripping, and then enter the recovery pool through the guide hole for collection. When the rectangular frame moves to the cotton strip, it will squeeze the internal maintenance liquid to lubricate and maintain the screw rod. At the same time, the magnetic rod and the sliding rod attract each other, and when the rectangular frame is reset, it will move with the cotton strip and the extension tube through the magnetic rod, and then the extension tube will wipe the tool with the cotton strip, thereby achieving wiping maintenance on the side of the tool, further improving maintenance efficiency, and increasing tool life.

[0041] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0042] like Figures 1 to 10 As shown, a chip rolling device for a CNC lathe for mechanical processing described in an embodiment of the present invention includes a lathe body 1, on which a tool holder 2 for mounting a tool 3 is provided; a replacement mechanism 10 for conveniently replacing the tool 3 is provided on the tool holder 2; the replacement mechanism 10 includes a servo motor 11 fixedly mounted on the tool holder 2, a screw rod 12 fixedly mounted on the output end of the servo motor 11, a rectangular frame 13 movably connected to the surface of the screw rod 12, an arc-shaped boss 14 fixedly mounted on a side of the rectangular frame 13 close to the tool 3, a plurality of rotating columns 15 rotatably connected to the surface of the boss 14, a plurality of slide grooves 16 are provided on one side of the tool holder 2, a slider 17 is slidably connected to the inside of the slide groove 16 through an elastic member 18, a clamping assembly 19 for fixing the tool 3 is provided on the top of the slider 17; the clamping assembly 19 includes a clamping plate 191 fixedly mounted on the slider 17, a bolt 192 is threadedly connected to the top of the clamping plate 191, and a rectangular plate for increasing the contact area with the tool 3 is fixedly mounted on the bottom of the bolt 192.

[0043] When working, before the lathe body 1 is working, the tools 3 to be used are placed in the clamping plate 191 in sequence, and the bolts 192 on the top of the clamping plate 191 are screwed, so that the bolts 192 and the rectangular plate at the bottom fix the tools 3 in the clamping plate 191. At this time, the tools 3 are in the initial position, and the ends of the multiple tools 3 are on the same horizontal line and in the tool holder 2. When the lathe body 1 starts to process parts, the servo motor 11 starts to work, and the servo motor 11 drives the rectangular frame 13 and the boss 14 on the screw rod 12 to start moving, and the required tool 3 is slid out by the cooperation of the boss 14 and the rotating column 15 (it should be noted that the tool holder 2 is in the initial position at this time and is not close to the part to be processed, so any movement of the tool 3 will not have any effect on the part to be processed, and when the tool 3 is replaced later, the tool holder 2 will return to the initial position to replace the tool 3, and will not have any effect on the part to be processed). The boss 14 is designed to be arc-shaped and the rotating column 15 is installed to reduce friction when the tool 3 is pushed, so as to facilitate the ejection of the tool 3. The movement of the tool 3 depends on the slider 17 in the slide groove 16, and when the tool 3 is not pushed by the boss 14, it will always remain in the initial position under the influence of the elastic member 18. Through the replacement mechanism 10 designed as above, all the tools 3 required for processing can be installed in the tool holder 2 in advance, and there is no need to stop the machine during processing. The tools 3 can be automatically replaced through CNC programming (which belongs to the existing technology and will not be described in detail here), thereby greatly improving the processing efficiency and reducing the need for constant calibration due to constant replacement.

[0044] A maintenance mechanism 20 for maintaining the tool 3 is arranged in the tool holder 2. The maintenance mechanism 20 includes a connecting plate 21 fixedly mounted on the tool holder 2. A hollow first elastic block 22 and a liquid storage box 24 pre-stored with maintenance liquid are fixedly mounted on the bottom of the connecting plate 21. A plurality of air outlet pipes 23 connected to the interior are fixedly mounted on one side of the first elastic block 22. The liquid storage box 24 and the first elastic block 22 are arranged in a stepped manner. An infusion tube 25 connected to the interior is fixedly mounted on one end of the liquid storage box 24. An ejection assembly 28 is arranged inside the rectangular frame 13. The ejection assembly 28 includes an electromagnet 282 electrically connected to the rectangular frame 13. A slide rod 281 made of magnetic material is slidably connected to the interior of the rectangular frame 13. An arc-shaped ejection block 283 is fixedly mounted on the top of the slide rod 281.

[0045] Specifically, a fixed tube 26 is fixedly installed on one side of the connecting plate 21 close to the cutter 3, and a plurality of nozzles 27 connected to the inside are fixedly installed on the surface of the fixed tube 26, and one end of the nozzle 27 is rotatably connected to an end cap 29 through a torsion spring, and one end of the infusion tube 25 away from the liquid storage box 24 is connected to the inside of the nozzle 27. The elastic member 18 is a hollow elastic ball, and a connecting tube 30 connected to the inside is fixedly installed on the surface of the elastic member 18, and one end of the connecting tube 30 away from the elastic ball is fixedly connected to the nozzle 27.

[0046] During operation, when the rectangular frame 13 moves, it will move with the top block 283. Since the tool 3 will generate iron chips when turning the parts, and the iron chips will splash after breaking, and the turning process requires cutting fluid for cooperation, the iron chips and cutting fluid will fall on the unused tool 3 on the tool holder 2, and the top block 283 will continuously squeeze the first elastic block 22 at the bottom of the connecting plate 21 when moving, so that the gas of the first elastic block 22 will be sprayed to the tool 3 through the outlet pipe 23, thereby blowing off the iron chips and cutting fluid on the tool 3. The iron chips remaining on the tool 3 can easily lead to uneven subsequent cutting, rough connection surface and inaccurate size, thereby shortening the service life of the tool 3. At this time, due to the corrosive substances contained in the cutting fluid (the main components of the cutting fluid are water, oil, rust inhibitors, surfactants, etc., which will not have a corrosive effect on the metal under normal circumstances. However, in some cases, the cutting fluid may cause corrosion. This is mainly because the cutting fluid may be contaminated during use, such as being mixed with impurities, metal ions, etc. These pollutants will cause the pH value of the cutting fluid to change, thereby causing corrosion problems), it will react with the tool 3 material, causing the tool 3 to corrode and rust.

[0047] When the cleaning effect of the tool 3 on the tool holder 2 is not ideal during the interval of replacing the tool 3, the replacement of the tool 3 can be suspended (the tool holder 2 is in the initial position at this time), and the servo motor 11 drives the rectangular frame 13 and the top block 283 to reciprocate at the bottom of the first elastic block 22, thereby squeezing the first elastic block 22 so that the gas inside it is quickly ejected through the air outlet pipe 23, thereby efficiently blowing off the residual iron filings and cutting fluid.

[0048] When the parts processing is completed and the tool 3 is no longer used, the rectangular frame 13 is moved toward the liquid storage box 24. When the rectangular frame 13 moves to the bottom of the liquid storage box 24, the electromagnet 282 inside the rectangular frame 13 is energized, so that the slide bar 281 moves with the top block 283 away from the electromagnet 282, and the top block 283 squeezes the liquid storage box 24. After the liquid storage box 24 is squeezed, the maintenance liquid (which can be anti-rust oil, lubricating oil box cleaning agent, depending on the actual situation) inside will enter the fixed pipe 26 and the nozzle 27 through the infusion tube 25, and the end cover 29 will be opened to open the nozzle 27, so that the maintenance liquid is sprayed onto the surface of the tool 3 through the nozzle 27, and the contraction of the elastic member 18 in the slide groove 16 will squeeze the gas inside, so that the gas is sprayed out through the connecting pipe 30, and the sprayed gas will blow the sprayed maintenance liquid to the surroundings, thereby increasing the spraying area of ​​the maintenance liquid, thereby completing the maintenance of the tool 3. Provide the service life of the tool 3.

[0049] The detection mechanism 40 includes a sleeve plate 41 fixedly mounted on the surface of the slide rod 281, and a second elastic block 42 fixedly mounted in the rectangular frame 13. A fixed frame 43 is fixedly mounted on a side of the rectangular frame 13 close to the tool 3. One end of the fixed frame 43 is sealingly and slidably connected to a sliding frame 44. A detector 45 is fixedly mounted on one end of the sliding frame 44 away from the fixed frame 43. The fixed frame 43 and the second elastic block 42 are connected via a conduit.

[0050] Specifically, a curved block 46 made of rubber is fixedly installed inside the second elastic block 42, and paint is pre-stored inside the curved block 46. A spray pipe 47 connected to the interior of the curved block 46 is fixedly installed on one side of the second elastic block 42, and one end of the spray pipe 47 away from the curved block 46 is fixedly connected to the sliding frame 44.

[0051] During operation, when the tool 3 is used and restored to the initial position, the electromagnet 282 is energized in advance when the rectangular frame 13 moves toward the direction of the liquid storage box 24, and the slide bar 281 moves with the sleeve plate 41 and squeezes the second elastic frame inside, allowing the gas in the second elastic frame to enter the fixed frame 43 through the conduit, and use the gas to push the sliding frame 44 and the detector 45 in the fixed frame 43 to slide in the direction away from the rectangular frame 13. The detector 45 will continuously detect the surface of the tool 3 when moving. When a worn tool 3 is detected, the electromagnet 282 increases the amount of electricity, so that the slide bar 281 and the sleeve plate 41 move away from the electromagnet 282 again. At this time, the sleeve plate 41 squeezes the arc block 46, so that the paint in the arc block 46 is sprayed on the tool 3 through the spray tube 47 for marking, thereby facilitating the subsequent staff to replace the damaged tool 3 in time, and avoiding the wear of the tool 3 affecting the processing accuracy of the parts.

[0052] A recovery mechanism 50 is provided on one side of the tool holder 2. The recovery mechanism 50 includes two protective cloths 51 fixedly connected to the slider 17. One end of the protective cloth 51 away from the slider 17 is fixedly connected to the inner wall of the slide groove 16. A guide hole 52 connected to the slide groove 16 is provided on the surface of the tool holder 2. The protective cloth 51 is inclined toward the guide hole 52. A recovery mechanism 50 is provided on one side of the tool holder 2. The recovery mechanism 50 includes two protective cloths 51 fixedly connected to the slider 17. One end of the protective cloth 51 away from the slider 17 is fixedly connected to the inner wall of the slide groove 16. A guide hole 52 connected to the slide groove 16 is provided on the surface of the tool holder 2. The protective cloth 51 is inclined toward the guide hole 52.

[0053] Specifically, an extension component 54 is provided on the support plate 532, and the extension component 54 includes a welding tube 541 fixedly installed on the support plate 532, one end of the welding tube 541 is slidably connected to the extension tube 542, one end of the extension tube 542 away from the welding tube 541 is fixedly connected to the cotton strip 533, and a magnetic rod 543 is fixedly installed on the top of the extension tube 542.

[0054] During operation, the sprayed lubricating oil is guided into the guide hole 52 after dripping by installing the inclined protective cloth 51, and then enters the recovery pool 531 through the guide hole 52 for collection. Since the cotton strip 533 is installed in the recovery pool 531, the maintenance liquid will completely soak the cotton strip 533. When the rectangular frame 13 moves to the cotton strip 533, the maintenance liquid inside will be squeezed, thereby lubricating and maintaining the screw rod 12. At the same time, the magnetic rod 543 and the slide bar 281 are attracted to each other by opposite sex (at this time, the electromagnet 282 has been powered off, and the slide bar 281 returns to the initial position). When the rectangular frame 13 is reset, it will move with the cotton strip 533 and the extension tube 542 through the magnetic rod 543, and then the extension tube 542 will wipe the tool 3 with the cotton strip 533, so as to achieve wiping and maintenance of the side of the tool 3, further improve the maintenance efficiency, and increase the service life of the tool 3. The protective cloth 51 installed at the same time can also reduce the impurities from entering the slide groove 16 and affecting the normal sliding of the slider 17.

[0055] Working principle: Before the lathe body 1 is put into operation, the tools 3 to be used are placed in the clamping plate 191 in sequence, and the bolts 192 on the top of the clamping plate 191 are screwed, so that the bolts 192 and the rectangular plate at the bottom fix the tools 3 in the clamping plate 191. At this time, the tools 3 are in the initial position, and the ends of several tools 3 are on the same horizontal line and in the tool holder 2. When the lathe body 1 starts to process parts, the servo motor 11 starts to work, and the servo motor 11 drives the rectangular frame 13 and the boss 14 on the screw rod 12 to start moving, and the boss 14 and the rotating column 15 cooperate to slide and eject the tool 3 to be used.

[0056] When the rectangular frame 13 moves, it will move with the top block 283, and the top block 283 will continuously squeeze the first elastic block 22 at the bottom of the connecting plate 21 when moving, so that the gas of the first elastic block 22 is sprayed to the tool 3 through the outlet pipe 23, thereby blowing off the iron filings and cutting fluid on the tool 3. When the cleaning effect of the tool 3 on the tool holder 2 is not ideal during the interval of replacing the tool 3, the replacement of the tool 3 can be stopped, and the servo motor 11 drives the rectangular frame 13 and the top block 283 to reciprocate at the bottom of the first elastic block 22, thereby squeezing the first elastic block 22, so that the gas inside it is quickly sprayed out through the outlet pipe 23, thereby efficiently blowing off the residual iron filings and cutting fluid. When the part processing is completed and the tool 3 is no longer used, the rectangular frame 13 is moved toward the liquid storage box 24. When the rectangular frame 13 moves to the bottom of the liquid storage box 24, the electromagnet 282 inside the rectangular frame 13 is energized, so that the slide bar 281 moves with the top block 283 in the direction away from the electromagnet 282, and the top block 283 squeezes the liquid storage box 24. After the liquid storage box 24 is squeezed, the maintenance liquid inside will enter the fixed tube 26 and the nozzle 27 through the infusion tube 25, and the end cover 29 will be pushed open to open the nozzle 27, so that the maintenance liquid is sprayed onto the surface of the tool 3 through the nozzle 27, and the contraction of the elastic member 18 in the slide groove 16 will squeeze the gas inside, so that the gas is sprayed out through the connecting tube 30, and the sprayed gas will blow the sprayed maintenance liquid to the surroundings, thereby increasing the spraying area of ​​the maintenance liquid.

[0057] When the tool 3 is used and restored to the initial position, the electromagnet 282 is energized in advance when the rectangular frame 13 moves toward the liquid storage box 24, and the slide bar 281 moves with the sleeve plate 41 and squeezes the second elastic frame inside, allowing the gas in the second elastic frame to enter the fixed frame 43 through the conduit, and use the gas to push the slide frame 44 and the detector 45 in the fixed frame 43 to slide in the direction away from the rectangular frame 13. The detector 45 will continuously detect the surface of the tool 3 when moving. When a worn tool 3 is detected, the electromagnet 282 increases the amount of electricity, so that the slide bar 281 and the sleeve plate 41 move away from the electromagnet 282 again. At this time, the sleeve plate 41 squeezes the arc block 46, so that the paint in the arc block 46 is sprayed on the tool 3 through the spray tube 47 for marking.

[0058] By installing the inclined protective cloth 51, the sprayed lubricating oil will be guided into the guide hole 52 after dripping, and then enter the recovery pool 531 through the guide hole 52 for collection. Since the cotton strip 533 is installed in the recovery pool 531, the maintenance liquid will completely soak the cotton strip 533. When the rectangular frame 13 moves to the cotton strip 533, the maintenance liquid inside will be squeezed to lubricate and maintain the screw rod 12. At the same time, the magnetic rod 543 and the sliding rod 281 attract each other. When resetting, the rectangular frame 13 will move together with the cotton strip 533 and the extension tube 542 through the magnetic rod 543, and then the extension tube 542 will wipe the tool 3 with the cotton strip 533, so as to achieve wiping and maintenance of the side of the tool 3.
