Description

Technical Field

[0001] This invention relates to the field of laser cutting equipment technology, and more specifically, to a cutting and grinding integrated machine for processing automotive die-cast aluminum parts. Background Technology

[0002] Laser cutting of cast aluminum parts is an advanced manufacturing technology that uses a high-energy laser beam to precisely cut cast aluminum materials.

[0003] Chinese patent application CN202210970299.8 discloses an automotive aluminum casting processing system, including a laser cutting system and a deburring system arranged sequentially according to the processing order, a conveying truss system mounted on the loading side of the laser cutting system and the deburring system, a conveying platform system located below the conveying truss system and arranged along the processing direction, and a gripping device slidably connected to the conveying truss system for loading and unloading workpieces on the conveying platform system, and also includes a control system.

[0004] The aforementioned technical solution enables rapid laser cutting and deburring of the external and internal contours of various shaped automotive aluminum castings. It can process complex and narrow contours with high efficiency and flexibility, meeting the production capacity requirements for automotive aluminum castings. However, when cutting die-cast aluminum parts, some laser cutting equipment uses a fixed-height laser cutter because the surface of the die-cast aluminum parts is uneven. While a fixed-height laser cutter is suitable for cutting flat surfaces, when the laser cutter moves... When the laser cutter reaches the convex surface, the vertical cutting height between the laser cutter and the convex surface decreases, which may cause the melting point temperature at the cutting line position on the convex surface to be high. After cooling, welding may occur again, affecting the cutting quality of the die-cast aluminum parts by the laser cutter. When the laser cutter moves to the concave surface, the vertical cutting height between the laser cutter and the concave surface increases, which may cause the cutting line on the concave surface to break in part. After the breakage occurs, the cutting needs to be repeated again, which not only affects the cutting quality of the die-cast aluminum parts by the laser cutter, but also affects the cutting efficiency of the die-cast aluminum parts by the laser cutter.

[0014] Preferably, a guide plate is fixedly installed on the bottom surface of the support platform, and a vertical frame is fixedly installed between the guide plate and the support platform.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1) When this integrated cutting and grinding machine for processing die-cast aluminum parts for automobiles is in use, during the laser cutter's cutting of the aluminum part body, when the traveling wheel moves to the convex surface, the convex surface squeezes the traveling wheel, causing the lifting plate to move upward, which in turn moves the laser cutter upward. This ensures that the vertical cutting distance of the laser cutter on the aluminum part body plane is the same as the vertical cutting distance on the convex surface. When the traveling wheel moves to the concave surface, the guide rod gradually moves downward under the action of the first spring, causing the U-shaped frame to move downward with the lifting plate, which in turn moves the laser cutter downward. This achieves the same vertical cutting distance on the aluminum part body plane as on the concave surface. Compared with some traditional laser cutting equipment, this laser cutter can achieve equal vertical cutting distances on different processing surfaces of the aluminum part body. It not only solves the problem of high melting point temperature at the cutting line position when the laser cutter cuts the convex surface, causing re-welding after cooling, but also solves the problem of partial breakage at the cutting line position when the laser cutter cuts the concave surface, thereby improving the cutting quality and efficiency of the laser cutter on the aluminum part body.

[0016] 2) When using this integrated cutting and grinding machine for processing die-cast aluminum parts for automobiles, the laser cutter is equipped with a protective plate that adjusts accordingly during the cutting process of the aluminum part. This effectively reduces the splashing of molten slag generated by the laser cutter onto the surface of the aluminum part and the traveling wheel, ensuring the smooth rolling of the traveling wheel on the surface of the aluminum part and further improving the cutting quality of the aluminum part by the laser cutter.

[0017] 3) When using this integrated cutting and grinding machine for processing die-cast aluminum parts for automobiles, before cutting the aluminum part, the telescopic device extends and lowers the fixed frame and Z-shaped plate. At this time, the sliding plate, sliding column, wheel seat, rotating wheel and grinding wheel move downward. When the laser cutter moves at a constant speed to cut the aluminum part, the rotating wheel is squeezed by the end surface of the aluminum part, which causes the wheel seat and sliding column to move upward. This causes the sliding plate to slide upward in the slide frame and compress the third spring. The two rotating wheels roll along both sides of the cutting groove. At this time, the grinding wheel is in the cutting groove. The micro motor works and drives the grinding wheel to rotate at high speed, so that the grinding wheel grinds and trims the inner walls on both sides of the cutting groove. With the uniform speed cutting laser cutter, the aluminum part can be cut and ground at one time, thereby improving the processing efficiency of the aluminum part. Attached Figure Description

[0020] Example 1: Please refer to Figure 1 - Figure 13A cutting and grinding integrated machine for processing die-cast aluminum parts for automobiles includes a support table 1 and an aluminum part body 2 to be cut, which is fixedly placed on the support table 1. The aluminum part body 2 is a conventional die-cast aluminum part in the prior art, and the surface of the die-cast aluminum part body 2 has a convex surface 3 and a concave surface 4, which are the surfaces formed by die casting in the prior art. A fixed frame 5 is provided above one end of the aluminum part body 2, and a lifting plate 6 is provided above the aluminum part body 2. The lifting plate 6 serves as a mounting plate for a laser cutter 10 and is located below the fixed frame 5. U-shaped frames 7 are fixedly installed on the corresponding side surfaces of the lifting plate 6. A through-type guide rod 8 is slidably connected to the surface of the fixed frame 5. The guide rod 8 is used to guide the movement of the lifting plate 6 during the lifting process. The bottom surfaces of the two guide rods 8 are fixedly connected to the two U-shaped frames 7 respectively. A first spring 9 for resetting the movement is sleeved on the surface of each guide rod 8. A laser cutter 10 for cutting the aluminum body 2 is fixedly installed in the middle of the bottom surface of the lifting plate 6. The laser cutter 10 is a conventional laser cutter 10 in the prior art. Wheels 11 are fixedly installed at both ends of the bottom surface of the lifting plate 6. Lower seats 12 are fixedly installed on both ends of the lifting plate 6. Upper seats 13 are fixedly installed at both ends of the bottom surface of the fixing frame 5. A micro-damper 14 is provided between the lower seat 12 and the upper seat 13. The micro-damper 14 is a conventional micro-damper 14 in the prior art. By setting the micro-damper 14, the laser cutter 10 can effectively ensure the cutting of concave shapes. To ensure stability during the process, a through-type slide rod 15 is slidably connected to the surface of the lifting plate 6. The slide rod 15 guides the movement of the protective plate 16. The bottom surfaces of the two slide rods 15 are jointly fixedly fitted with a protective plate 16 to protect the traveling wheels 11. The protective plate 16 can effectively reduce the splashing of molten slag generated by the laser cutter 10 when cutting the aluminum body 2 onto the surfaces of the aluminum body 2 and the traveling wheels 11. A base frame 17 is fixedly installed on the bottom surface of the protective plate 16. An arc-shaped frame 18 is fixedly installed on one end surface of each of the two base frames 17. The arc design of the arc-shaped frame 18 facilitates the adjustment of the protective plate 16 when it moves to the convex surface 3. Rollers 19 are provided on the bottom surfaces of both the base frame 17 and the arc-shaped frame 18. During the cutting of the aluminum part body 2, when the traveling wheel 11 moves to the convex surface 3, the convex surface 3 presses against the traveling wheel 11, causing the lifting plate 6 to move upward, which in turn moves the laser cutter 10 upward. This ensures that the vertical cutting distance of the laser cutter 10 on the plane of the aluminum part body 2 is the same as the vertical cutting distance of the laser cutter 10 on the convex surface 3. When the traveling wheel 11 moves to the concave surface 4, the guide rod 8 gradually moves downward under the action of the first spring 9, causing the U-shaped frame 7 to move downward with the lifting plate 6, which in turn moves the laser cutter 10 downward. This again achieves the same vertical cutting distance of the laser cutter 10 on the plane of the aluminum part body 2 as the vertical cutting distance of the laser cutter 10 on the concave surface 4. Compared with some traditional laser cutting equipment, this method achieves a significant improvement.The laser cutter 10 can perform equal perpendicular cutting distances on different processing surfaces of the aluminum part body 2. This not only solves the problem of high melting point temperature at the cutting line and subsequent welding after cooling when cutting convex surfaces, but also addresses the issue of partial breakage at the cutting line when cutting concave surfaces. This improves the cutting quality and efficiency of the laser cutter 10 on the aluminum part body 2. During the cutting process, a dynamically adjustable protective plate 16 effectively reduces molten slag splashing onto the aluminum part body 2 and the surface of the traveling wheel 11, ensuring the smooth rolling of the traveling wheel 11 on the surface of the aluminum part body 2 and further improving the cutting quality of the laser cutter 10 on the aluminum part body 2.

[0021] Please see Figure 8 - Figure 12 One end of the miniature damper 14 is fixedly connected to the surface of the lower seat 12, and the other end of the miniature damper 14 is fixedly connected to the bottom surface of the upper seat 13. One end of the first spring 9 is fixedly connected to the surface of the U-shaped frame 7, and the other end of the first spring 9 is fixedly connected to the bottom surface of the fixed frame 5. The U-shaped frame 7 is elastically connected to the fixed frame 5 through the first spring 9. The first spring 9 is used for the reset of the lifting plate 6. When the walking wheel 11 moves to the concave surface 4, in order to prevent the walking wheel 11 from dropping instantly and causing the first spring 9 to reset rapidly and causing reciprocating jumping, the miniature damper 14 is set to effectively ensure the stability of the laser cutter 10 in the process of cutting the concave surface 4.

[0022] Please see Figure 10 and Figure 11 A common fixing plate 20 is fixedly installed on the top surface of the two slide rods 15. A second spring 21 is sleeved on the surface of each slide rod 15. One end of the second spring 21 is fixedly connected to the bottom surface of the common fixing plate 20, and the other end of the second spring 21 is fixedly connected to the surface of the lifting plate 6. Two through slots 22 that match the slide rods 15 are opened on the surface of the lifting plate 6. The slide rods 15 are slidably connected to the lifting plate 6 through the through slots 22. The spring force of the second spring 21 is less than the spring force of the first spring 9.

[0023] Please see Figure 1 - Figure 7Two sets of brackets 23 are fixedly installed on the surface of the support platform 1. The distance between one set of brackets 23 is greater than the distance between the other set of brackets 23, so that the aluminum body 2 can be pushed flat onto the surface of the support platform 1. A slide block 24 is fixedly installed on the bottom surface of the middle of the two sets of brackets 23. A matching slider 25 is slidably connected inside the slide block 24. A telescopic device 26 is fixedly installed on the bottom surface of the slider 25. A connecting frame 27 is fixedly installed on the surface of the fixed frame 5. The telescopic end of the telescopic device 26 is fixedly connected to the connecting frame 27. The telescopic device 26 is a conventional electric control push rod in the prior art. The telescopic device 26 is electrically connected to the controller 31 through a wire. The controller 31 controls the telescopic device 26 to extend and retract, which is the prior art. It will not be described in detail here.

[0024] Please see Figure 3 and Figure 4 The slide 24 is internally rotatably connected to a lead screw 28, which is threadedly connected to the slider 25. A motor 29 is fixedly mounted on one end surface of the slide 24, and the output end of the motor 29 is fixedly connected to the lead screw 28. The motor 29 is a conventional forward and reverse reversing motor in the prior art.

[0025] Please see Figure 1 and Figure 2 A base 32 is provided below the support platform 1. A support seat 33 is fixedly installed between the base 32 and the support platform 1. A mounting bracket 30 is fixedly installed on the side surface of the base 32. A controller 31 is fixedly installed on the surface of the mounting bracket 30. The controller 31 is a conventional programmable control device in the prior art. The controller 31 is electrically connected to the motor 29 through wires. The controller 31 controls the operation of the motor 29, which is the prior art and will not be described in detail here.

[0026] Please see Figure 3 - Figure 5 The surface of the aluminum body 2 is provided with a cutting groove 34. The surface of the support platform 1 is rotatably connected to multiple turntables 35. A bracket 36 is fixedly installed on the surface of any turntable 35. The surface of the bracket 36 is threadedly connected to a threaded rod 37. The bottom surface of the threaded rod 37 is rotatably connected to a fixing plate 39 for fixing the aluminum body 2. The bottom surface of the fixing plate 39 is equipped with a rubber pad to prevent damage to the surface of the aluminum body 2. A knob 38 is fixedly installed on the top surface of the threaded rod 37. The surface of the support platform 1 is provided with a through-type lower slot 40. The turntable 35 is manually rotated so that the multiple fixing plates 39 rotate to the four corners of the surface of the aluminum body 2. Then, the knob 38 is manually rotated so that the threaded rod 37 is screwed down and the fixing plates 39 are lowered to fix the aluminum body 2.

[0027] Please see Figure 4 A guide plate 54 is fixedly installed on the bottom surface of the support platform 1. A vertical frame 55 is fixedly installed between the guide plate 54 and the support platform 1. The guide plate 54 is designed so that the cutting slag and grinding chips fall into the guide plate 54 for diversion and collection.

[0028] The steps of using this invention are as follows: When using this integrated cutting and grinding machine for processing die-cast aluminum parts for automobiles, firstly, push the aluminum part body 2 from one of the sets of supports 23 with a large distance between them onto the surface of the support table 1. Then, manually rotate the turntable 35 so that the multiple fixed plates 39 rotate to the four corners of the surface of the aluminum part body 2. Then, manually rotate the knob 38, and the threaded rod 37 rotates downward, causing the fixed plates 39 to descend and fix the aluminum part body 2. Then, operate the controller 31 so that the telescopic device 26 extends and moves the cutting equipment downward. During the descent of the cutting equipment, firstly, the rollers 19 on the bottom surface of the base frame 17 contact the surface of the aluminum part body 2. Then, after being squeezed by the aluminum part body 2, the rollers 19 move upward with the base frame 17 and the protective plate 16, and then move upward with the sliding rod 15 and the co-fixing plate. The second spring 21 is stretched upwards by the extension mechanism 26. As the extension mechanism 26 continues to extend, the two traveling wheels 11 contact the surface of the aluminum body 2 again. After being compressed, the two traveling wheels 11 move upwards along with the lifting plate 6, which in turn causes the U-shaped frame 7 to move upwards, along with the guide rod 8, to compress the first spring 9. At this time, the lower seat 12 moves and compresses the micro damper 14. When the vertical cutting distance between the laser cutter 10 and the aluminum body 2 is appropriate, the extension mechanism 26 stops moving. Then, the controller 31 is operated to make the motor 29 work, causing the lead screw 28 to rotate. This causes the slider 25 to slide at a constant speed within the slide block 24, moving the laser cutter 10 (the laser cutter 10 also starts working at the same time as the motor 29). The traveling wheels 11 are on the plane of the aluminum body 2. During rolling, the laser cutter 10 cuts a cutting groove 34 on the plane of the aluminum body 2. When the traveling wheel 11 moves to the convex surface 3, the convex surface 3 squeezes the traveling wheel 11, causing the lifting plate 6 to move upward, which in turn moves the laser cutter 10 upward, making the vertical cutting distance of the laser cutter 10 on the plane of the aluminum body 2 the same as the vertical cutting distance of the laser cutter 10 on the convex surface 3. When the traveling wheel 11 moves to the concave surface 4, the guide rod 8 gradually moves downward under the action of the first spring 9, causing the U-shaped frame 7 to move downward with the lifting plate 6, which in turn moves the laser cutter 10 downward, achieving the same vertical cutting distance of the laser cutter 10 on the plane of the aluminum body 2 and the same vertical cutting distance of the laser cutter 10 on the concave surface 4. Before the traveling wheel 11 moves to the convex surface 3, the roller 19 on the bottom surface of the arc frame 18 first contacts the convex surface 3. At this time, the arc frame 18 moves upward, taking the base frame 17 and the protective plate 16 upward, and then taking the slide rod 15 and the co-fixed plate 20 upward to stretch the second spring 21. During the process of the laser cutter 10 cutting the aluminum body 2, the setting of the protective plate 16 can effectively reduce the splashing of molten slag generated by the laser cutter 10 cutting the aluminum body 2 onto the surface of the aluminum body 2 and the traveling wheel 11, ensuring the smooth rolling of the traveling wheel 11 on the surface of the aluminum body 2. When the traveling wheel 11 moves to the concave surface 4, in order to prevent the traveling wheel 11 from dropping suddenly and causing the first spring 9 to rapidly reset and cause reciprocating jumping, a micro damper 14 is set.This design effectively ensures the stability of the laser cutter 10 during the cutting of the concave surface 4. During the cutting of the aluminum body 2, when the traveling wheel 11 moves to the convex surface 3, the convex surface 3 compresses the traveling wheel 11, causing the lifting plate 6 to move upwards, carrying the laser cutter 10 upwards. This ensures that the vertical cutting distance of the laser cutter 10 on the plane of the aluminum body 2 is the same as the vertical cutting distance on the convex surface 3. When the traveling wheel 11 moves to the concave surface 4, the guide rod 8 gradually moves downwards under the action of the first spring 9, causing the U-shaped frame 7 to move downwards, carrying the lifting plate 6 downwards, and thus causing the laser cutter 10 to move downwards. This again achieves the same vertical cutting distance of the laser cutter 10 on the plane of the aluminum body 2 as the vertical cutting distance on the concave surface 4. Compared to traditional methods... This laser cutter 10, part of the conventional laser cutting equipment, can perform equal perpendicular cutting distances on different processing surfaces of the aluminum part body 2. It not only solves the problem of high melting point temperature at the cutting line when cutting convex surfaces, leading to re-welding after cooling, but also addresses the issue of partial breakage at the cutting line when cutting concave surfaces. This improves the cutting quality and efficiency of the laser cutter 10 on the aluminum part body 2. During the cutting process, a dynamically adjustable protective plate 16 effectively reduces molten slag splashing onto the aluminum part body 2 and the surface of the traveling wheel 11, ensuring the smooth rolling of the traveling wheel 11 on the surface of the aluminum part body 2, further enhancing the cutting quality of the laser cutter 10 on the aluminum part body 2.

[0029] Example 2: Please refer to Figure 5 - Figure 13The difference from embodiment 1 is that two Z-shaped plates 41 are fixedly installed on the side surface of the fixing frame 5. A slide 42 is fixedly installed on the surface of the Z-shaped plate 41. A matching slide plate 43 is slidably connected inside the slide 42. A through-type slide column 44 is slidably connected to the surface of the Z-shaped plate 41. The slide column 44 is used to guide the movement of the wheel seat 45. A wheel seat 45 is fixedly installed on the bottom surface of both slide columns 44. A rotating wheel 46 is rotatably connected inside the wheel seat 45. A grinding wheel 47 for grinding the inner wall of the cutting groove 34 is provided between the two rotating wheels 46. The grinding wheel 47 is a conventional grinding wheel 47 in the prior art. Before cutting the aluminum body 2, the telescopic device 26 extends and lowers the fixing frame 5 and the Z-shaped plate 41. At this time... The sliding plate 43, sliding column 44, wheel seat 45, rotating wheel 46, and grinding wheel 47 move downwards. When the laser cutter 10 moves at a constant speed to cut the aluminum body 2, the rotating wheel 46 is squeezed by the end surface of the aluminum body 2, which causes the wheel seat 45 and sliding column 44 to move upwards. This causes the sliding plate 43 to slide upwards in the slide frame 42, compressing the third spring 50. The two rotating wheels 46 roll along both sides of the cutting groove 34. At this time, the grinding wheel 47 is in the cutting groove 34. The micro motor 53 works to drive the grinding wheel 47 to rotate at high speed, so that the grinding wheel 47 grinds and trims the inner walls on both sides of the cutting groove 34. With the uniform cutting of the laser cutter 10, the aluminum body 2 can be cut and ground in one go, thereby improving the processing efficiency of the aluminum body 2.

[0030] The top surfaces of the two sliding pillars 44 are fixedly connected to the bottom surface of the slide plate 43. A third spring 50 is elastically connected between the slide plate 43 and the carriage 42. The third spring 50 is used for the return of the slide plate 43 to its original position. One end of the third spring 50 is fixedly connected to the surface of the slide plate 43, and the other end is fixedly connected to the carriage 42. A shielding arc plate 48 is fixedly installed above the grinding wheel 47. The shielding arc plate 48 reduces the splashing of grinding debris. Connecting pillars 49 are fixedly installed on both sides of the shielding arc plate 48 and the two sliding pillars 44. The surface of the Z-shaped plate 41... A through groove 51 is provided on the surface, and the sliding column 44 is slidably connected to the Z-shaped plate 41 through the through groove 51. L-shaped plates 52 are fixedly installed on the inner side of both wheel seats 45. The grinding wheel 47 is rotatably connected to the two L-shaped plates 52. A micro motor 53 is fixedly installed on the surface of one of the L-shaped plates 52. The output end of the micro motor 53 is fixedly connected to the grinding wheel 47. The micro motor 53 is electrically connected to the controller 31 through a wire. The micro motor 53 is a conventional micro motor 53 in the prior art. The controller 31 controls the micro motor 53 to work, which is the prior art and will not be described in detail here.

[0031] The steps of using this invention are as follows: When using this integrated cutting and grinding machine for processing die-cast aluminum parts for automobiles, before cutting the aluminum part body 2, the telescopic device 26 extends and lowers the fixed frame 5 and Z-shaped plate 41. At this time, the sliding plate 43, sliding column 44, wheel seat 45, rotating wheel 46 and grinding wheel 47 move downward. When the laser cutter 10 moves at a constant speed to cut the aluminum part body 2, the rotating wheel 46 is squeezed by the end surface of the aluminum part body 2, which causes the wheel seat 45 and sliding column 44 to move upward, so that the sliding plate 43 slides upward in the slide frame 42 to compress the third spring 50. The two rotating wheels 46 roll along both sides of the cutting groove 34. At this time, the grinding wheel 47 is in the cutting groove 34. The micro motor 53 works to drive the grinding wheel 47 to rotate at high speed, so that the grinding wheel 47 grinds and trims the inner walls on both sides of the cutting groove 34. With the uniform cutting of the laser cutter 10, the aluminum part body 2 can be cut and ground at one time, thereby improving the processing efficiency of the aluminum part body 2.
