Technical Field

[0001] This invention relates to the field of shaft machining technology, specifically to a machining center for shaft machining. Background Technology

[0002] Shafts are mainly used to support transmission components, transmit torque, and bear loads. Based on their structural form, shafts can generally be divided into three categories: plain shafts, stepped shafts, and irregularly shaped shafts; or solid shafts, hollow shafts, etc. During the manufacturing process of shafts, a turning tool is needed to machine the rotating shaft to meet the forming requirements. When turning shafts, the turning tool comes into contact with the rapidly rotating shaft, causing the tool to heat up. Since shafts vary in length, different positions need to be machined during turning, resulting in a constantly changing tool position. This makes it difficult to cool the tool, making it susceptible to damage from high temperatures. Furthermore, the turning process generates a lot of debris, and the large dispersion area of ​​the debris makes collection difficult. Summary of the Invention

[0017] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0018] Furthermore, in this invention, the use of terms such as "first" and "second" is for descriptive purposes only and does not specifically refer to any order or sequence, nor is it intended to limit the invention. They are merely used to distinguish components or operations described using the same technical terms and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions and features of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If a combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0019] The present invention provides the following embodiments. Example 1: This embodiment of the invention provides a machining center for shaft machining, such as... Figures 1-3 As shown, the device includes an outer shell 1. Cabinet doors 2 are symmetrically arranged on the left and right sides of the front end of the outer shell 1. A positioning and clamping mechanism is installed on the internal worktable of the outer shell 1. The positioning and clamping mechanism is used to clamp the shaft 48 to be processed. The positioning and clamping mechanism is connected to the stabilization control mechanism. The stabilization control mechanism is connected to the cutting mechanism. The cutting mechanism is in corresponding contact with the shaft 48 to be processed. A cooling and collecting component is connected to the cutting mechanism. The internal worktable of the outer casing 1 is the lower inner surface of the outer casing 1.

[0020] The working principle of the above technical solution is as follows: When machining the shaft 48, cabinet door 2 is opened, and the shaft 48 is positioned and clamped by the positioning and clamping mechanism. The shaft 48 is then rotated. The cutting mechanism moves the cutting tool left-right and forward-backward to perform cutting on the shaft 48. The stabilization control mechanism controls the rotation of the positioning and clamping mechanism and the movement of the cutting mechanism. As the rotation speed of the positioning and clamping mechanism increases, the stabilization control mechanism increases the clamping force on the shaft 48 to prevent instability in the connection between the shaft 48 and the positioning and clamping mechanism under centrifugal force. Simultaneously, the stabilization control mechanism slows down the movement speed of the cutting mechanism to prevent excessive speed from causing instantaneous contact between the cutting tool and the shaft 48. Excessive impact force affects the machining effect of the shaft 48 to be machined. The cooling and collection component is installed on the cutting mechanism and moves synchronously with the cutting mechanism to ensure that the cooling and collection component moves with the tool. When the tool of the cutting mechanism is cutting the shaft 48 to be machined, it can always cool the contact end between the tool and the shaft 48 to be machined, avoiding tool damage. At the same time, it is convenient to collect metal waste, avoiding manual cleaning, saving time and effort. It solves the technical problem that when turning shaft parts need to be machined at different positions, the position of the turning tool is constantly changing, making it inconvenient to cool the turning tool, making the turning tool easy to be damaged by high temperature. At the same time, a lot of chips are generated during the turning process, and the chip dispersion area is too large, making it inconvenient to collect the chips.

[0021] Example 2: Based on Example 1, as follows Figures 1-5 As shown, the positioning and clamping mechanism includes fixed shells 4 symmetrically arranged on the left and right sides of the upper end of the worktable. Rotating rings are symmetrically arranged at the left and right ends of the fixed shells 4. The rotating rings are rotatably connected to the fixed shells 4. Several arc-shaped blocks 13 are evenly distributed around the inner ring of the rotating ring. The arc surfaces of the arc-shaped blocks 13 connected to the left and right rotating rings are inclined in opposite directions. The outer ring of the rotating ring is fixedly connected to the toothed ring 12. The rear part of the left toothed ring 12 on the left fixed shell 4 meshes with the gear 11. The gear 11 is fixedly connected to the drive shaft 7. The drive shaft 7 is fixedly connected to the motor 3 on the worktable. A positioning ring 49 is provided through the middle of the fixed shell 4 and is rotatably connected to the fixed shell 4. Positioning holes 18 are provided through the left and right ends of the positioning ring 49. Several insertion ports are evenly distributed circumferentially on the left and right sides of the positioning ring 49. Several insertion ports are slidably connected to several insertion rods 15 one by one. The middle part of the insertion rod 15 is threadedly connected to the sliding block 16. The sliding block 16 is slidably connected to the fixed shell 4. A spring 17 is fixed between the sliding block 16 and the positioning ring 49. The spring 17 is sleeved on the insertion rod 15. The end of the insertion rod 15 near the positioning hole 18 is rotatably connected to the fixed block 50. The end of the insertion rod 15 away from the positioning hole 18 is in corresponding contact with the arc-shaped block 13.

[0022] The working principle of the above technical solution is as follows: When machining and positioning the shaft 48, the control rod 15 rotates, creating a relative displacement between the rod 15 and the sliding block 16. The rod 15 moves towards the positioning hole 18, causing the fixing block 50 to move. The circumferentially distributed rods 15 rotate the same number of times, ensuring the same relative displacement distance between the fixing block 50 and the sliding block 16. The moving of several fixing blocks 50 circumferentially distributed along the positioning hole 18 clamps and fixes the shaft 48. The spring 17 has sufficient elasticity to keep the sliding block 16 and the fixed housing 4 as relatively stationary as possible. This prevents the fixing block 50 from moving under its own weight after the shaft 48 comes into contact with the fixing block 50. The fixing block 50 is a rough block, ensuring sufficient friction between the fixing block 50 and the shaft 48 after contact. The friction force is large enough to prevent relative rotation between the fixed block 50 and the shaft to be processed 48, and to make the axis of the shaft to be processed 48 coincide with the axis of the positioning hole 18. Then, the motor 3 is started, the motor 3 drives the drive shaft 7 to rotate, the drive shaft 7 drives the gear 11 to rotate, the gear 11 drives the left gear ring 12 to rotate, the left gear ring 12 drives the left arc block 13 to rotate, the left arc block 13 contacts the left insertion rod 15 and squeezes the left insertion rod 15 to prevent the insertion rod 15 from driving the fixed block 50 to move away from the shaft to be processed 48, thereby ensuring the squeezing and fixing effect of the fixed block 50 on the shaft to be processed 48. Then, the left insertion rod 15 is driven to rotate, the left insertion rod 15 drives the positioning ring 49 to rotate, the positioning ring 49 drives the fixed block 50 to rotate, thereby driving the shaft to be processed 48 to rotate. If the shaft to be processed 48 is long enough, the positioning and clamping mechanism in the right fixed shell 4 can also position the shaft to be processed 48, which improves the rotational stability of the shaft to be processed 48. The arc surfaces of the left and right arc blocks 13 are tilted in opposite directions. When the positioning ring 49 rotates and drives the right insert rod 15 to rotate, the right insert rod 15 contacts the arc surface of the right arc block 13, and drives the right toothed ring 12 to rotate through the right arc block 13.

[0023] Example 3: Based on Example 2, such as Figures 1-7 As shown, the stabilization control mechanism includes a working shell 9 connected to the front part of the toothed ring 12 connected to the left fixed shell 4 and the rear part of the toothed ring 12 connected to the right fixed shell 4. The working shell 9 has an air intake chamber 51 inside. The left end of the working shell 9 is rotatably connected to the rotating shaft 23. The rotating shaft 23 is fixedly connected to the gear 8 outside. The gear 8 meshes with the toothed ring 12 on the left side of the fixed shell 4. The end of the rotating shaft 23 away from the gear 8 is fixedly connected to the air supply fan 24 inside the air intake chamber 51. The right end of the working shell 9 is fixedly connected to the second rotating shaft 25. A fixed plate 20 is fixedly sleeved on the second rotating shaft 25. An air inlet is provided at the end of the second rotating shaft 25 near the working shell 9. A cavity is provided inside the fixed plate 20. An exhaust pipe 26 is provided at the side end of the fixed plate 20. The air inlet chamber 51, the air inlet, the cavity and the exhaust pipe 26 are connected in sequence. A grinding disc 42 is slidably provided in the cavity. The grinding disc 42 is in corresponding contact with the grinding disc 21. The grinding disc 21 is fixedly connected to the third gear 10. The third gear 10 is rotatably connected to the second rotating shaft 25. The third gear 10 meshes with the gear ring 12 on the right side of the fixed shell 4. The second rotating shaft 25 is fixedly connected to the first support plate 27. The first support plate 27 is fixedly set on the worktable. The drive shaft 7 is fixedly connected to the rotating shaft 23 that connects to the working housing 9 on the rear side.

[0024] The working principle of the above technical solution is as follows: The left gear ring 12 drives the second gear 8 to rotate, which in turn drives the first rotating shaft 23 to rotate. The first rotating shaft 23 then drives the air supply fan 24 to rotate, drawing outside air into the intake chamber 51. This air enters the intake port and cavity, pushing the grinding disc 42 towards the grinding disc 21. The grinding disc 42 slides along the cavity until it contacts the grinding disc 21, which acts as a brake. The friction between the grinding disc 42 and the grinding disc 21 increases the force required for the grinding disc 21 and its connected third gear 10 to rotate. The rotation of the right gear ring 12 requires the third gear 10 to rotate, thus increasing the force required for its rotation. The faster the rotation speed of the left gear ring 12 and the rotation speed of the shaft 48 it is clamping, the faster the air supply fan 24 rotates, resulting in a larger amount of air entering the intake chamber 51 per unit time. The greater the air pressure in cavity 51, the longer the movement distance of the grinding disc 42, the greater the friction between the grinding disc 42 and the grinding disk 21, and the greater the force required for the right toothed ring 12 to rotate. After the right insert rod 15 contacts the arc surface of the right arc block 13, it pushes the right toothed ring 12 to rotate. As the force required for the right toothed ring 12 to rotate increases, after the right insert rod 15 contacts the arc surface of the right arc block 13, the right arc block 13 pushes the right insert rod 15 to continue moving towards the shaft to be processed 48. Since the right fixed block 50 contacts the shaft to be processed 48, the right insert rod 15 and the right sliding block 16 have a tendency to move synchronously, and the spring 17 has a tendency to compress, which increases the squeezing force of the right fixed block 50 on the shaft to be processed 48 and improves the squeezing and fixing effect of the right fixed block 50 on the shaft to be processed 48. The exhaust pipe 26 acts as a pressure relief pipe, preventing the air pressure in the intake chamber 51 from becoming infinitely high. This ensures that the maximum friction between the grinding disc 42 and the grinding disk 21 is less than the friction between the fixed block 50 and the shaft to be processed 48 after clamping and fixing in embodiment 2. This prevents the friction between the grinding disc 42 and the grinding disk 21 from being too large, which would prevent the right toothed ring 12 from rotating and thus cause relative displacement between the right fixed block 50 and the shaft to be processed 48, affecting the positioning and clamping effect of the right fixed block 50 on the shaft to be processed 48. The increased force required for the rotation of the right toothed ring 12 is achieved by the right arc-shaped block 13 pushing the right insertion rod 15. As the rotation speed of the left toothed ring 12 and the shaft to be processed 48 increases, the squeezing force of the right insertion rod 15 on the shaft to be processed 48 through the right fixed block 50 increases synchronously. This ensures that the squeezing force of the positioning and clamping mechanism increases synchronously with the increase in the rotation speed of the shaft to be processed 48, improving the clamping stability of the positioning and clamping mechanism on the shaft to be processed 48.

[0025] Example 4: Based on Example 3, such as Figures 1-8 As shown, the cutting mechanism includes a drive screw 6, which is fixedly connected to a drive motor 5. The drive screw 6 is rotatably mounted on a support plate 27 and a support plate 2. The support plate 2 is fixedly mounted on the worktable. The drive motor 5 is fixedly connected to the support plate 2. The drive screw 6 is threadedly connected to a drive block 28. The drive block 28 is slidably mounted on the upper end of the worktable in the left-right direction. A mounting shell 30 is slidably mounted on the upper end of the drive block 28 in the front-back direction. A mounting opening 47 is provided at the rear end of the mounting shell 30. Clamping blocks 38 are symmetrically arranged on the left and right sides of the mounting opening 47. The clamping blocks 38 on the left and right sides are used to clamp the cutting tool. The clamping blocks 38 are slidably connected to the mounting opening 47. The front inclined section of the clamping block 38 is slidably connected to the rear inclined section of the pushing block 37. The front end of the pushing block 37 is rotatably connected to the threaded rod 36. The threaded rod 36 is threadedly connected to the threaded hole on the threaded sleeve 34. The threaded sleeve 34 is rotatably connected to the front end of the mounting shell 30. The threaded sleeve 34 is fixedly connected to the connecting plate 32. Limiting holes 35 are provided through the front and rear ends of the connecting plate 32. The threaded hole and the limiting hole 35 are correspondingly connected. The limiting hole 35 is slidably connected to the limiting rod 14. The limiting rod 14 is rotatably connected to the sliding plate 33. The sliding plate 33 is threadedly connected to the screw. The screw is fixedly connected to the second drive motor 29. The second drive motor 29 is fixedly installed in the driving block 28. The exhaust pipe 26 connected to the front working shell 9 is connected to the exhaust pipe 22. The exhaust pipe 22 is connected to the pneumatic telescopic rod 19. The pneumatic telescopic rod 19 is provided with a pressure relief port. The movable section of the pneumatic telescopic rod 19 is fixedly connected to the drive block 28.

[0026] The working principle of the above technical solution is as follows: When fixing the tool, first place the tool in the mounting port 47 so that the end of the tool contacts the push block 37. Then rotate the connecting plate 32, which drives the threaded sleeve 34 to rotate. When the threaded sleeve 34 rotates, it drives the threaded rod 36 to move towards the shaft to be processed 48 (backward). The threaded rod 36 drives the push block 37 to move backward. The push block 37 and the mounting port 47 slide relative to each other. The inclined section of the push block 37 drives the clamping blocks 38 on the left and right sides to move towards each other. The clamping blocks 38 on the left and right sides clamp and fix the tool. At the same time, the push block 37 limits the end of the tool, thus completing the purpose of tool installation. If the tool is to be removed, rotate the connecting plate 32 in the opposite direction so that the threaded rod 36 moves forward, and finally the push block 37 moves forward, driving the clamping blocks 38 on the left and right sides to move away from each other, so that the clamping blocks 38 release the tool, making it easy to remove and replace the tool. When the tool moves back and forth, the second drive motor 29 is activated. The second drive motor 29 drives the screw to rotate, which in turn drives the sliding plate 33 to move backward. The sliding plate 33 then drives the limiting rod 14 to move backward. When the tool moves towards the shaft to be processed 48, the limiting rod 14 moves backward along the limiting hole 35 until it contacts the threaded rod 36. The limiting rod 14 then pushes the threaded rod 36 backward, which in turn drives the pushing block 37 to move backward. The clamping block 38 drives the tool to move towards the shaft to be processed 48, and the mounting shell 30 moves backward along the upper end of the drive block 28. After the tool head contacts the shaft to be processed 48, the shaft to be processed 48 is processed. The limiting rod 14 is designed to pass directly through the limiting hole 35 and the threaded hole to contact the threaded rod 36. When the tool is cutting the shaft to be processed 48, it can prevent the threaded rod 36 and the threaded hole from sliding relative to each other due to excessive force, which would affect the clamping block 38's clamping and fixing of the tool. When the second drive motor 29 operates in reverse, the second drive motor 29 drives the sliding plate 33 to move forward through the screw. The sliding plate 33 drives the limiting rod 14 to move forward. The limiting rod 14 moves forward along the limiting hole 35 until the limiting rod 14 can no longer move along the limiting hole 35. Then it drives the connecting plate 32 to move forward. The connecting plate 32 drives the threaded sleeve 34 to move forward. The threaded sleeve 34 drives the mounting shell 30 and the threaded rod 36 to move forward. The mounting shell 30 moves forward along the upper end of the drive block 28. The threaded rod 36 drives the push block 37 and the threaded sleeve 34 to move forward synchronously. The push block 37 drives the clamping block 38 and the mounting shell 30 to move forward synchronously. This drives the tool to move in a direction away from the axis to be processed 48 (forward), thus achieving the purpose of driving the tool to move back and forth. When the tool moves left and right, drive motor 5 is started. Drive motor 5 drives drive screw 6 to rotate, and drive screw 6 drives drive block 28 to move left and right. In the initial state, that is, when the shaft to be machined 48 is not being machined, drive block 28 is located on the upper right side of the worktable. When machining the shaft to be machined 48, drive screw 6 rotates and drives drive block 28 to move to the left. At this time, air supply fan 24 supplies air into air intake chamber 51, and the gas discharged from exhaust pipe 22 enters pneumatic telescopic rod 19. When drive block 28 moves to the left and compresses pneumatic telescopic rod 19, it can increase the force required to compress pneumatic telescopic rod 19, thereby increasing the force required for drive block 28 to move. At this time, the torque of drive motor 5 increases and the speed decreases, achieving the purpose of slowing down the tool movement speed. The pressure port is used to prevent excessive gas pressure in the pneumatic telescopic rod 19. If the speed of motor 3 increases, the air pressure in the air inlet chamber 51 and the pneumatic telescopic rod 19 connected through the exhaust pipe 22 will increase, thereby synchronously reducing the speed of drive motor 5. This prevents the tool from moving too fast and the machining shaft 48 from rotating too fast, which would result in excessive clockwise impact force between the tool and the machining shaft 48, causing damage to both. After machining is completed, after the tool moves forward and disengages from the machining shaft 48, drive motor 5 is controlled to drive drive screw 6 to rotate in the opposite direction. Drive block 28 moves to the right to return to its original position, and pneumatic telescopic rod 19 returns to its original position. After motor 3 stops working, the air pressure inside pneumatic telescopic rod 19 finally returns to its initial value under the pressure relief effect of the pressure relief port.

[0027] Example 5: Based on Example 4, such as Figures 1-9 As shown, the cooling and collecting assembly includes a storage shell fixedly disposed at the rear end of the drive block 28. A U-shaped shell 45 is fixedly disposed at the upper end of the storage shell, with an opening in the U-shaped shell 45 for the cutter to pass through. The U-shaped shell 45 is fixedly connected to the spray shell 46, with the spray nozzle of the spray shell 46 facing the cutter head. A recovery shell 31 is fixedly disposed at the rear end of the storage shell, with a recovery chamber 44 at the upper end of the recovery shell 31. A filter screen is installed at the connection between the recovery chamber 44 and the storage chamber inside the storage shell. A pusher plate 4 is slidably disposed in the recovery chamber 44. 3. The lower part of the push plate 43 is provided with a return port. The rear end of the push plate 43 is fixedly connected with a rack 40. The drive shaft 7 is movably connected with the sliding block 39. The left and right ends of the sliding block 39 are symmetrically provided with sector gears 41. The sector gears 41 are slidably connected with the drive shaft 7. The upper and lower sides of the sector gears 41 are respectively meshed with racks 40. The end of the rack 40 away from the push plate 43 is fixedly connected to the connecting plate 52. The rear end of the recovery shell 31 is provided with a through hole for the straight section of the lower rack 40 to pass through.

[0028] The working principle of the above technical solution is as follows: When the drive block 28 moves left and right, it can drive the recovery shell 31 to move left and right through the storage shell. The storage shell contains lubricating fluid. When the tool is machining the shaft 48 to be machined, a power pump is installed in the U-shaped shell 45. The power pump works, causing the lubricating fluid to be sprayed through the spray nozzle onto the contact end between the tool and the shaft 48 to be machined, reducing the friction between the tool and the shaft 48 to be machined and cooling it down. The fallen lubricating fluid and metal scrap fall into the recovery chamber 44. The lubricating fluid flows back into the storage chamber through the filter screen, which is used to separate the lubricating fluid and metal scrap. The recovery shell 31 drives the sliding block 39 to move left and right. As the drive shaft 7 rotates, the drive shaft 7 drives the sector gear 41 to rotate. When the sector gear 41 meshes with the upper rack 40, it disengages from the lower rack 40. The rotation of the sector gear 41 causes the upper and lower racks 40 to move in opposite directions. The upper and lower racks 40 drive the push plate 43 to move back and forth in the front-back direction. The through hole and the straight section of the lower rack 40 are sealed and slide, ensuring the sealing of the recovery chamber 44. The push plate 43 moves back and forth along the recovery chamber 44. The setting of the return port allows the lubricating fluid to pass through the return port, reducing the resistance of the lubricating fluid on the push plate 43. The movement of the push plate 43 is used to accelerate the flow of the lubricating fluid and also facilitates the pushing of metal scraps in the lubricating fluid to the front and back sides of the recovery chamber 44, which is convenient for collecting the metal scraps.
