Although the dual-spindle turning center magnetically attracts metal chips generated during machining, some metal chips are affected by the water mist sprayed for cooling during machining, resulting in a reduced magnetic attraction effect. Furthermore, the cooling water spray is difficult to collect and utilize.

[0004] In view of this, the present invention proposes a modular parallel spindle turning center to remedy and improve the deficiencies of the prior art. Summary of the Invention

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The present invention is provided with a cooling and polishing switching mechanism. When turning a part, the gear disc is controlled to rotate, and the switching member connected to the spray pipe is moved in conjunction with the mechanism. The switching member is prompted to move and penetrate the inner core of the part, and the pump extracts cooling liquid from the liquid storage tank.

The rotation of the fan blade cooperates with the air collecting pipe to collect the metal debris blocked in the protective cover, preventing the metal debris from splashing outward and causing damage to the operator, and facilitating the centralized treatment of the metal debris by the operator.

[0021] The cleaning mechanism provided in the present invention can also utilize the guide hopper to guide and drain the cooling liquid sprayed toward the turned parts, so that the cooling liquid and metal debris move toward the filter screen. While the filter screen concentrates and collects the metal debris, the cooling liquid is recovered through the filter screen, which is beneficial to the recycling of the cooling liquid and saves the cost of using the device.

[0037] Embodiments of the present invention

[0038] Please refer to Figures 1-9 As shown, a modular parallel spindle turning center includes a processing base 6, on which a spindle body 1 is fixedly mounted, including:

[0039] A chuck 2 is rotatably connected to the spindle body 1;

[0040] The turning part 5 is arranged at the center of the chuck 2;

[0041] The cooling and polishing switching mechanism 3 is provided between the spindle body 1 and the chuck 2, and is used for simultaneously spraying liquid to cool the inside and outside of the turned part 5 and polishing the inner core of the turned part 5;

[0042] A cleaning mechanism 4 is provided between the chuck 2 and the turned part 5, and is used to recover the debris generated by turning the turned part 5 and the water mist used for cooling;

[0043] The cooling and polishing switching mechanism 3 includes a first motor 31 fixedly mounted on the inner wall of the spindle body 1. The output end of the first motor 31 is fixedly connected to a gear disc 32. Two sets of switching members 33 are symmetrically arranged between the gear disc 32 and the spindle body 1.

[0044] The switching member 33 includes a rack 331 slidably connected to the inner wall of the spindle body 1, and the rack 331 is meshed with the toothed disc 32. The end of the rack 331 near the chuck 2 is fixedly connected to a supply pipe 333, and a spring 334 is fixedly connected to the inner wall of the supply pipe 333. A push rod 335 is slidably connected to the inner wall of the supply pipe 333, and the push rod 335 abuts against the spring 334.

[0045] The switching member 33 includes a guide frame 332 fixedly connected to the inner wall of the main shaft body 1, a guide rod 336 fixedly connected to the outer surface of the push rod 335, and a bearing seat 337 fixedly connected to the end of the push rod 335 away from the supply and transfer tube 333;

[0046] A polishing rod 35 is fixedly mounted on the outer surface of one of the bearing seats 337 , and a spray pipe 34 is connected to the other bearing seat 337 , and the spray pipe 34 is connected to the first liquid discharge pipe 36 ;

[0047] The cooling and polishing switching mechanism 3 also includes a liquid storage tank 311 threadedly connected to the spindle body 1. A pump 37 is fixedly mounted on the liquid storage tank 311 and is connected to the first liquid discharge pipe 36. The end of the pump 37 near the liquid storage tank 311 is connected to the liquid extraction pipe 310. The top end of the pump 37 is connected to the second liquid discharge pipe 38. The end of the second liquid discharge pipe 38 near the turned part 5 is connected to the nozzle 39.

[0048] Supplementary explanation: A limit slot is provided on the inner wall of the main shaft body 1, and a limit slider is fixedly connected to the outer surface of the rack 331, and the limit slider slides on the limit slot;

[0049] The turned part 5 is a component with a through-hole core in the center, and the diameters of the polishing rod 35 and the spraying pipe 34 are adapted to the diameter of the through-hole core of the turned part 5;

[0050] The guide frame 332 is L-shaped and is used to provide sliding guidance for the guide rod 336;

[0051] A support ring is fixedly connected to the outer surface of the spindle body 1, and the support ring is fixed to the second liquid discharge pipe 38. 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;

[0052] The above solution adopts: through the cooling and polishing switching mechanism 3, when the turned part 5 is turned, the gear disc 32 is controlled to rotate, which in turn causes the switching member 33 connected to the spray pipe 34 to move, prompting the spray pipe 34 to move and penetrate the inner core of the turned part 5. The pump 37 draws cooling liquid from the liquid storage tank 311, so that part of the drawn cooling liquid is atomized and sprayed onto the outside of the turned part 5 through the second liquid discharge pipe 38 and the nozzle 39, while the other part of the cooling liquid is sprayed onto the inner core of the turned part 5 through the spray pipe 34, thereby achieving simultaneous cooling of the inside and outside of the turned part 5, improving the cooling effect of the turned part 5, and increasing the service life of the device;

[0053] 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 part 33 on which the polishing rod 35 is fixed to move, so as to prompt 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 while improving the cleaning efficiency of the inner core of the turned part 5.

[0054] Please refer to Figure 2 and Figure 3 As shown, the cleaning mechanism 4 includes a second motor 41 fixedly mounted on the outer surface of the processing base 6, the output end of the second motor 41 is fixedly connected to a rotating shaft 44, the outer surface of the rotating shaft 44 is fixedly connected to a gear 42, the outer surface of the rotating shaft 44 is fixedly connected to a fan blade 45, the outer surface of the chuck 2 is fixedly connected to a gear ring 43, and the gear ring 43 is meshed with the gear 42;

[0055] The cleaning mechanism 4 further includes an air collecting pipe 46 fixedly connected to the outer surface of the processing base 6. The end of the air collecting pipe 46 away from the gear 42 is connected to a guide hopper 47. The bottom end of the air collecting pipe 46 is fixedly connected to a filter screen 48. The outer surface of the processing base 6 is slidably connected to a protective cover 7.

[0056] Supplementary explanation: The air collecting pipe 46 is T-shaped, and the end of the air collecting pipe 46 close to the gear 42 is wrapped around the outside of the fan blade 45. The air collecting pipe 46 is located at one end below the guide hopper 47 and is used to connect to the storage tank for recovering the cooling liquid;

[0057] The protective cover 7 is wrapped around the guide hopper 47 and the outside of the turned part 5. Transparent glass is installed on the protective cover 7. The protective cover 7 is used to prevent metal debris generated by the turning part 5 from spreading outward;

[0058] Magnetic blocks are fixedly mounted on both sides of the top surface of the filter 48, and the magnetic blocks are used to magnetically attract metal debris;

[0059] The above solution adopts: the cleaning mechanism 4 is provided, and the gear 42 and the fan blade 45 can be rotated accordingly by utilizing the continuous rotation of the rotating shaft 44. The rotation of the gear 42 is linked to the rotation of the gear ring 43, thereby causing the chuck 2 and the turned part 5 to rotate accordingly, thereby facilitating the turning of the turned part 5. The rotation of the fan blade 45 cooperates with the air collecting pipe 46 to collect the metal debris blocked by the protective cover 7, preventing the metal debris from splashing outward and causing damage to the operator, and facilitating the centralized processing of the metal debris by the operator;

[0060] Through the cleaning mechanism 4, the guide hopper 47 can also be used to guide and drain the cooling liquid sprayed toward the turned parts 5, so that the cooling liquid and metal debris move toward the filter 48. The filter 48 collects the metal debris while allowing the cooling liquid to pass through the filter 48 for centralized recovery, which is beneficial to the recycling of the cooling liquid and saves the cost of using the device.

[0061] It should be further explained that: one switching member 33 is used to carry and install the spray pipe 34, and the other switching member 33 is used to carry and install the polishing rod 35. The two sets of switching members 33 are moved in opposite directions by the rotation of the toothed disc 32. That is, when one guide rod 336 moves along the guide frame 332 toward the turned part 5, the spring 334 is pulled by the push rod 335 and is in an extended state, and the guide frame 332 aligns its corresponding installation object with the inner core of the turned part 5. The other guide rod 336 moves along the guide frame 332 toward the liquid storage tank 311, and the corresponding spring 334 is reset and contracted, so that the guide frame 332 avoids the corresponding installation object, so that the above-mentioned object aligned with the inner core of the turned part 5 can smoothly enter the inner core of the turned part 5;

[0062] The working principle and use process of the present invention:

[0063] Preliminary preparation: The staff first fills the cooling liquid into the liquid storage tank 311, and then screws the cooling liquid storage tank 311 onto the main spindle body 1;

[0064] During the turning process of the turned 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 to the gear 42, the outer surface of the rotating shaft 44 is fixedly connected to the fan blade 45, and the outer surface of the chuck 2 is fixedly connected to the gear ring 43, the gear ring 43 and the gear 42 are meshed and matched, so that the gear ring 43 and the fan blade 45 rotate along with the rotation of the rotating shaft 44. The rotation of the gear ring 43 will link the chuck 2 and the turned part 5 to rotate accordingly, making it easier for the turned part 5 to cooperate with the tool for turning. The rotation of the fan blade 45 will collect metal debris blocked in the protective cover 7 through the air collecting duct 46 and the protective cover 7.

[0065] Next, 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 gear disc 32, two sets of switching members 33 are symmetrically arranged between the gear disc 32 and the main shaft body 1, and the rack 331 is meshed with the gear disc 32. The 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 to the spring 334, and the inner wall of the supply pipe 333 is slidably connected to the push rod 335, the push rod 335 abuts against the spring 334, and the outer surface of the push rod 335 The surface of the support 337 is fixedly connected to the guide rod 336. The end of the push rod 335 away from the supply and transfer tube 333 is fixedly connected to the support seat 337. The polishing rod 35 is fixedly installed on the outer surface of one support seat 337. The other support seat 337 is connected to the spray pipe 34, and the spray pipe 34 is connected to the first liquid discharge pipe 36. The support seat 337 connected to the spray pipe 34 is urged to move toward the turned part 5 along with the clockwise rotation of the gear disc 32 until the spray pipe 34 penetrates into the inner core of the turned part 5. At this time, the first motor 31 is controlled to stop.

[0066] Then, the operator operates 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 near 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 near the turned part 5 is connected to the nozzle 39, prompting the pump 37 to draw cooling liquid from the liquid storage tank 311 through the liquid extraction pipe 310. Part of the drawn cooling liquid is sprayed onto the inner core of the turned part 5 through the spray pipe 34, while the other part of the cooling liquid is sprayed into an atomized form onto the outside of the turned part 5 through the second liquid discharge pipe 38 and the nozzle 39, thereby achieving simultaneous cooling of the inside and outside of the turned part 5, thereby improving the cooling effect of the turned part 5.

[0067] 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 rotate the gear disc 32 counterclockwise. At this time, the support seat 337 connected to the spray pipe 34 moves toward the liquid storage tank 311 until the corresponding guide rod 336 slides off the guide frame 332. At this time, the support seat 337 is pulled by the spring 334 and avoids the polishing rod 35 opposite to it. The support 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 the inner core of the turned part 5 and pushing the metal debris trapped in the inner core of the turned part 5 out of the turned part 5.

[0068] 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 debris move toward the filter 48. The filter 48 collects the metal debris while allowing the cooling liquid to pass through the filter 48 for centralized recovery.

[0069] Summary: The cooling and polishing switching mechanism 3 is provided 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 cooperates with the pump 37, the first discharge pipe 36 and the second discharge pipe 38 to spray the inside and outside of the turned part 5, thereby achieving simultaneous cooling of the inside and outside of the turned part 5, improving the cooling effect of the turned part 5, and increasing 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 while improving the cleaning efficiency of the inner core of the turned part 5;

[0070] By setting up 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 turning 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 processing of the metal debris by the personnel. The guide hopper 47 is utilized to guide and drain the cooling liquid sprayed toward the turning part 5, so that the cooling liquid and the metal debris move toward the filter 48. The filter 48 collects the metal debris in a centralized manner, and the cooling liquid is recovered through the filter 48 in a centralized manner, which is conducive to the recycling of the cooling liquid and saves the cost of using the device.
