Description

Technical Field

[0001] The invention relates to the technical field of laser cutting processing, in particular to a flip-type laser cutting machine for processing automobile transmission spindles. Background Art

[0002] The main shaft of a car is a key component in the car's transmission system, responsible for transmitting the engine's power from the transmission to the wheels. It is usually composed of a shaft tube, a telescopic sleeve and a universal joint, where the universal joint is used to connect shafts of different axes to adapt to the angle changes during vehicle driving.

[0003] In the existing automobile transmission spindle processing process, laser cutting machines are usually required. Traditional laser cutting machines have some shortcomings: traditional equipment usually uses simple mechanical clamps or fixtures to fix and support the spindle. These methods are prone to loosening after long-term work, causing the spindle to shift or shake during processing, thereby affecting the processing accuracy. For spindle ends with complex geometric shapes, such as parts with bevels, curved surfaces or multiple feature surfaces, due to the long automobile transmission spindle, traditional equipment is difficult to achieve multi-angle precision cutting, and usually requires multiple clamping and adjustment, which increases error accumulation and processing time. During the processing process, the stability of the spindle is the key to ensuring high-precision cutting. During the flipping or moving process, the spindle is prone to loosening or slipping, affecting the processing quality. Summary of the invention

[0014] Preferably, a first electric guide rail is fixedly connected to the top of the machine body. A second electric guide rail is fixedly connected inside the first electric guide rail through an execution end. A five-axis cutting head is fixedly connected to the bottom of the second electric guide rail through an execution end.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. This application causes multiple guide rods to gradually move towards the center of the fixed annular platform, thereby driving multiple sliding plates to gradually move towards the center of the fixed annular platform. When the multiple sliding plates move, they drive multiple fixing plates and support wheels to move, causing the multiple support wheels to gradually fit against the outer wall of the main shaft. The edges of the multiple support wheels are set as arc surfaces, enabling the multiple support wheels to fit against the main shaft, thereby supporting and fixing the main shaft. This facilitates the start of the five-axis cutting head to cut the main shaft, causing the anti-slip pads to remain in contact with the main shaft. The multiple anti-slip pads are in close contact with the main shaft, constructing a stable support structure. Since the main shaft remains stationary, this close contact can ensure that the main shaft does not displace or shake during the laser cutting process, thereby providing a solid foundation for high-precision cutting. At the same time, multiple springs are compressed with multiple sliding rods, achieving precise buffer alignment. This alignment method helps to ensure that the relative position between the main shaft and the five-axis cutting head always remains stable, reducing cutting errors caused by position deviations. At the same time, the multiple anti-slip pads increase the friction force on the main shaft, preventing the main shaft from shifting and rolling during the processing.

[0017] 2. This application causes the rear end of the moving platform to lift upwards, flipping the support platform and the main shaft upwards. Because the top of the workbench is set as a sunken type, it is convenient for the main shaft to deflect, causing the end of the main shaft to rise, cooperating with the five-axis cutting head to process the end of the main shaft. When cutting and processing the end of the main shaft, since the main shaft can be flipped, multi-angle cutting can be achieved. By precisely controlling the flipping angle of the main shaft, the end of the main shaft can be cut on different planes. For example, it can be cut on a horizontal plane first, then flipped by a certain angle to cut on an inclined plane, and then flipped to another angle for supplementary cutting. This can complete complex cutting shapes in one go, reducing the error accumulation caused by multiple clamping and adjustment, and improving the cutting accuracy. For the ends of some main shafts with complex geometric shapes, such as components with inclined surfaces, curved surfaces, or multiple feature surfaces, the main shaft flipping function can ensure that the laser beam always irradiates the part to be cut at an appropriate angle, achieving precise cutting.

[0018] 3. This application causes the threaded rod to move horizontally when rotating, driving the lower support plate and the support sleeve to move, thereby adjusting the position of the support sleeve. The support sleeve can support the bottom end of the main shaft, preventing the main shaft from loosening, slipping, and improving the stability of the main shaft. Cooperating with the limit component to release the main shaft, the movement of the support sleeve can support the bottom end of the main shaft, thereby adjusting the position of the main shaft inside the limit component, facilitating the adjustment of the fixed area of the main shaft and facilitating processing.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

The translation components include slide rails 3, lead screws 4, moving blocks 5, and mounting plates 6. A moving table 15 is arranged on the top of the workbench 2. The two slide rails 3 are respectively fixedly connected to both sides of the top of the workbench 2. The two lead screws 4 are respectively rotatably connected to the inside of the two slide rails 3. Motors with output ends connected to the lead screws 4 are installed at one end of the two slide rails 3 facing the body 1 for driving the lead screws 4 to rotate. The two moving blocks 5 are respectively slidably connected to the inside of the two slide rails 3. The two lead screws 4 respectively penetrate the two moving blocks 5 and are threadedly connected to the two moving blocks 5. The two mounting plates 6 are respectively fixedly connected to the tops of the two moving blocks 5. By rotating the lead screws 4, the moving blocks 5 are driven to move inside the slide rails 3, thereby driving the moving table 15 to move horizontally.

[0036] On both sides of the bottom of the mobile station 15, upper L-shaped plates 11 are fixedly connected. On the top of the two mounting plates 6, lower L-shaped plates 7 are fixedly connected. At the front end of the bottom of the two upper L-shaped plates 11, hinge plates 9 are fixedly connected. On one side of the front end of the two lower L-shaped plates 7, rotating shafts 8 are fixedly connected. The two rotating shafts 8 respectively penetrate through the two hinge plates 9 and are rotatably connected with the two hinge plates 9. At one end of the two rotating shafts 8 extending outside the hinge plates 9, baffle plates 10 are fixedly connected. The two baffle plates 10 are respectively attached to the two hinge plates 9 to support and limit the hinge plates 9, prevent them from falling off, and improve stability. On the rear sides of the two lower L-shaped plates 7, hydraulic cylinders 12 are fixedly connected. The output ends of the two hydraulic cylinders 12 respectively penetrate through the two lower L-shaped plates 7 and are slidably connected with the two lower L-shaped plates 7. The output ends of the two hydraulic cylinders 12 are both fixedly connected with connecting plates 14. On one side of the two connecting plates 14, push rods 13 are hinged. The two push rods 13 are respectively hinged to the inner sides of the two upper L-shaped plates 11. By driving the connecting plates 14 to move through the output ends of the hydraulic cylinders 12, the connecting plates 14 push the push rods 13 to move, so as to make the push rods 13 push the upper L-shaped plates 11 to flip around the rotating shafts 8.

[0037] At the top of the front end of the mobile station 15, a limiting component for fixing the main shaft is provided. The limiting component includes a support table 16, two support rings 17, a fixed ring platform 18 and a plurality of sliding plates 19. The plurality of sliding plates 19 all penetrate through the fixed ring platform 18 and are slidably connected with the fixed ring platform 18. On both sides of one end where the plurality of sliding plates 19 are close to each other, two support wheels 21 are rotatably connected. On the outer sides of the two support rings 17, guide plates 31 are rotatably connected. On the front and rear sides of the support table 16, sliding grooves 30 are opened. The two guide plates 31 are respectively slidably connected inside the two sliding grooves 30. Inside the two guide plates 31, a plurality of guide grooves 32 are arranged in an annular array. At the top ends of the plurality of sliding plates 19, guide rods 29 are fixedly connected. The plurality of guide rods 29 respectively penetrate through the plurality of guide grooves 32 and are slidably connected with the plurality of guide grooves 32. Through the plurality of guide grooves 32, the plurality of guide plates 31 are guided, so that when the guide plates 31 rotate, they drive the plurality of guide rods 29 to contract inwards or outwards. On one side of the bottom of the two guide plates 31, tooth grooves 33 are opened. At the front and rear ends of one side of the support table 16, support blocks 34 are fixedly connected. Inside the two support blocks 34, a rotating rod 35 is rotatably connected. At both ends of the rotating rod 35, limit gears 36 are fixedly connected. The two limit gears 36 are respectively meshed with the two tooth grooves 33. By rotating the rotating rod 35, the two limit gears 36 are driven to move, and the two guide plates 31 are driven to rotate synchronously. One end of the rotating rod 35 is fixedly connected with a worm gear 37. On one side of the top of the mobile station 15, a first forward and reverse motor 40 and a limit block 38 are fixedly connected. The output end of the first forward and reverse motor 40 is fixedly connected with a worm 39. The worm 39 is meshed with the worm gear 37. One end of the worm 39 away from the first forward and reverse motor 40 is rotatably connected with the limit block 38, so that the limit block 38 drives the worm gear 37 to rotate and drives the rotating rod 35 to rotate.

[0038] An anti-slip component for preventing the main shaft from rolling is provided inside each of the multiple skateboards 19. The anti-slip component includes a slide bar 22 and an anti-slip backing plate 23. The multiple slide bars 22 are respectively slidably connected inside the multiple skateboards 19, and the multiple anti-slip backing plates 23 are respectively fixedly connected to the bottom ends of the multiple slide bars 22. Fixing plates 20 are fixedly connected to the bottoms of the multiple skateboards 19. Grooves adapted to the anti-slip backing plates 23 are provided on both sides of the multiple fixing plates 20. Springs 24 are fixedly connected to one ends of the multiple slide bars 22 facing the inside of the skateboards 19, and the other ends of the multiple springs 24 are respectively fixedly connected to the multiple skateboards 19. Slide cavities 25 are provided on both sides inside the multiple skateboards 19. A plurality of through holes are provided in an annular array inside the multiple slide cavities 25. Piston plates 26 are slidably connected inside the multiple slide cavities 25. One sides of the multiple piston plates 26 are fixedly connected to moving rods 27. The multiple moving rods 27 respectively penetrate through the multiple skateboards 19 and are slidably connected to the multiple skateboards 19. Fixing blocks 28 are fixedly connected to one ends of the multiple moving rods 27 extending outside the skateboards 19. The multiple fixing blocks 28 are respectively fixedly connected to both sides of the multiple anti-slip backing plates 23. By sliding the piston plates 26 inside the slide cavities 25, a damping effect is formed to buffer the slide bars 22 and the anti-slip backing plates 23 in cooperation with the springs 24.

[0039] A support component for supporting the end of the main shaft is provided inside the support ring 17. The support component includes a limit rotating cylinder 41, a threaded rod 43, a lower support plate 46, a support sleeve 47 and a threaded sleeve 54. Horizontal plates 42 are integrally formed on both sides inside the limit rotating cylinder 41. Limit grooves are provided on both sides of the threaded rod 43. The two horizontal plates 42 are respectively slidably connected inside the two limit grooves and are adapted to the two limit grooves. The threaded sleeve 54 is fixedly connected to the rear side of the support ring 17. The threaded rod 43 penetrates through the threaded sleeve 54 and is threadedly connected to the threaded sleeve 54. The rear end of the threaded rod 43 is rotatably connected to an upper support plate 44. Limit rods 45 are fixedly connected to both sides of the upper support plate 44. One ends of the two limit rods 45 away from the upper support plate 44 are respectively fixedly connected to the two lower support plates 46. The support sleeve 47 is fixedly connected to one side of the lower support plate 46. The bottom end and the front end of the threaded rod 43 are rotatably connected to the lower support plate 46. A second forward and reverse motor 49 is fixedly connected to one side of the top of the moving table 15. The output end of the second forward and reverse motor 49 is fixedly connected to a guide gear 50. A transmission gear 48 is fixedly connected to one end of the limit rotating cylinder 41. The guide gear 50 is meshed with the transmission gear 48 to drive the limit rotating cylinder 41 to rotate, so that the limit rotating cylinder 41 drives the threaded rod 43 to rotate synchronously.

[0040] When this solution is in use, the automotive drive main shaft passes through the support ring 17, and one end of the main shaft is placed inside the support sleeve 47. The first reversible motor 40 is started, causing the first reversible motor 40 to drive the worm 39 to rotate, and the worm 39 drives the worm gear 37 to rotate. When the worm gear 37 rotates, it drives the rotating rod 35 to rotate. Furthermore, during the rotation of the rotating rod 35, the limiting gears 36 at both ends are driven to rotate, causing the two limiting gears 36 to drive the two guide plates 31 to rotate synchronously. When the two guide plates 31 rotate, the multiple guide grooves 32 formed inside them rotate. Since the trajectories of the multiple guide grooves 32 gradually contract from the outside to the inside, the multiple guide grooves 32 limit and guide the multiple guide rods 29, causing the multiple guide rods 29 to gradually move towards the center of the fixed ring platform 18, thereby driving the multiple sliding plates 19 to gradually move towards the center of the fixed ring platform 18. When the multiple sliding plates 19 move, they drive the multiple fixing plates 20 and the supporting wheels 21 to move, causing the multiple supporting wheels 21 to gradually fit against the outer wall of the main shaft. The edges of the multiple supporting wheels 21 are set as arc surfaces, enabling the multiple supporting wheels 21 to fit against the main shaft, thereby supporting and fixing the main shaft, facilitating the start of the five-axis cutting head 53 to cut the main shaft.

[0041] Before the multiple supporting wheels 21 approach the main shaft, the multiple anti-slip pads 23 will first come into contact with the main shaft. After the multiple anti-slip pads 23 come into contact with the main shaft, since the multiple sliding plates 19 are still moving, the multiple anti-slip pads 23 push the multiple sliding rods 22 to slide into the multiple sliding plates 19. The multiple sliding rods 22 push the multiple springs 24 and compress the multiple springs 24. At the same time, when the anti-slip pads 23 move, they drive the fixing blocks 28 on both sides to move, causing the fixing blocks 28 to drive the moving rods 27 to move, thereby causing the moving rods 27 to drive the two piston plates 26 to move, and the two piston plates 26 slide inside the sliding cavity 25. The sliding cavity 25 can be filled with a buffer solution, enabling the buffer solution to flow through the multiple through holes when the piston plates 26 move inside the sliding cavity 25, improving the damping effect, and cooperating with the springs 24 to buffer the sliding rods 22, causing the anti-slip pads 23 to remain in contact with the main shaft. The multiple anti-slip pads 23 are in close contact with the main shaft, constructing a stable support structure. Since the main shaft remains stationary, this close contact can ensure that the main shaft does not displace or shake during the laser cutting process, thereby providing a solid foundation for high-precision cutting. At the same time, the multiple springs 24 and the multiple sliding rods 22 are compressed, achieving precise buffer alignment. This alignment method helps to ensure that the relative position between the main shaft and the five-axis cutting head 53 always remains stable, reducing cutting errors caused by position deviations. At the same time, the multiple anti-slip pads 23 increase the friction force on the main shaft, preventing the main shaft from shifting and rolling during the processing.

[0042] It is started by two hydraulic cylinders 12, which drive two connecting plates 14 to move, and the two connecting plates 14 push two push rods 13 to move forward, and the two push rods 13 push two upper L-shaped plates 11 to turn over, and the two upper L-shaped plates 11 drive two hinge plates 9 to rotate around the rotating shaft 8, so that the rear end of the moving platform 15 is lifted upward, and the support platform 16 and the main shaft are turned over upward. Because the top of the workbench 2 is set to be sunken, it is convenient for the main shaft to deflect, the end of the main shaft rises, and it cooperates with the five-axis cutting head 53 to process the end of the main shaft. When cutting and processing the end of the main shaft, since the main shaft can be turned over, multi-angle cutting can be realized. By precisely controlling the turning angle of the main shaft, the end of the main shaft can be cut on different planes. For example, it can be cut on the horizontal plane first, then turned over by a certain angle and cut on the inclined plane, and then turned over to another angle for supplementary cutting. In this way, complex cutting shapes can be completed at one time, reducing the error accumulation caused by multiple clamping and adjustment, and improving the cutting accuracy. For the ends of some main shafts with complex geometric shapes, such as components with inclined surfaces, curved surfaces or multiple feature surfaces, the main shaft turning function can ensure that the laser beam always irradiates the part to be cut at a suitable angle, realizing precise cutting.

[0043] It is started by the second forward and reverse motor 49, which drives the guide gear 50 to rotate. When the guide gear 50 rotates, it drives the transmission gear 48 and the limit rotating cylinder 41 to rotate, and the cross plates 42 on both sides inside the limit rotating cylinder 41 limit the limit grooves opened on both sides of the threaded rod 43, thereby driving the threaded rod 43 to rotate synchronously. Because the threaded rod 43 is threadedly connected with the threaded sleeve 54, the threaded rod 43 moves horizontally when rotating, and the threaded rod 43 drives the lower support plate 46 and the support sleeve 47 to move, so as to adjust the position of the support sleeve 47. The bottom end of the main shaft can be supported by the support sleeve 47 to prevent the main shaft from loosening and slipping when lifted, improving the stability of the main shaft. Cooperating with the limit component to release the main shaft, the movement of the support sleeve 47 can support the bottom end of the main shaft, thereby adjusting the position of the main shaft inside the limit component, facilitating the adjustment of the fixed area of the main shaft and being convenient for processing.

[0044] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above-mentioned exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention.
