Description

Technical Field

[0001] This invention belongs to the field of laser cutting of auto parts, specifically a cutting platform for automotive parts. Background Technology

[0002] There are many types of automotive parts, but most of them are initially manufactured by cutting metal sheets. Laser cutting technology is commonly used in the processing of automotive parts. The metal sheet is supported by a rack and toothed plate, and the cutting head moves along a preset path to complete the cutting to form the initial processing of the automotive parts. The high-temperature slag generated during the cutting process mainly falls into the gap between the rack and toothed plates and is collected and processed by the bottom collection device.

[0003] A patent document with announcement number CN214721546U discloses a precision laser cutting device suitable for automotive parts, including a worktable, a first drive mechanism and a second drive mechanism. A fixing mechanism is installed on the second drive mechanism, and a laser head is installed on the fixing mechanism. A slider is slidably installed inside the slide groove, and a baffle is fixedly installed on the upper surface of the slider. The baffle is slidably installed on the upper surface of the worktable.

[0004] Traditional techniques use a one-piece molded support frame and supporting racks to support the plates. Then, a multi-axis moving laser cutting head cuts the metal plates. After multiple cuts, the supporting racks on the one-piece molded structure will be damaged, requiring the entire structure to be replaced. The one-piece molded support structure is heavy and occupies a large area, making it difficult to replace. In addition, the spacing between the multiple supporting racks in traditional techniques is fixed, making it difficult to achieve the best cutting effect while increasing the practicality of the entire device for metal plates of varying thicknesses.

[0005] Therefore, the present invention provides a cutting platform for automotive parts to solve the problems mentioned in the background art. Summary of the Invention

[0006] The technical solution adopted by the present invention to solve its technical problem is as follows: The present invention provides a cutting platform for automotive parts, including a cutting table and a processing cavity opened inside the cutting table. A multi-axis moving table is slidably installed above the cutting table, and a laser cutting head is movably installed above the multi-axis moving table. A support assembly is installed inside the processing cavity. The support assembly includes a rigid support member fixedly installed inside the processing cavity and multiple support racks detachably installed above the rigid support member. The multiple support racks are evenly distributed and installed above the rigid support member. Multiple load-bearing racks and multiple lifting components are movably installed at the bottom of the processing cavity. The multiple load-bearing racks are raised and lowered inside the processing cavity by the multiple lifting components. A set of load-bearing racks is movably installed at the middle vertical surface position of two adjacent load-bearing racks.

[0007] Preferably, the rigid support member has multiple slots evenly distributed inside, and multiple support racks are inserted and installed inside the corresponding slots. Multiple triangular teeth are evenly distributed and installed above the support racks.

[0008] Preferably, the bottom of the processing cavity is provided with multiple lifting slots, and multiple lifting components are installed in the corresponding lifting slots. Two lifting components on the same vertical plane are used to control the lifting of a corresponding set of load-bearing racks.

[0009] Preferably, the lifting component includes a lifting box that is lifted and installed inside the lifting groove and a connecting member installed on the side of the lifting box, the end of which is connected to the lower side of the load-bearing rack.

[0010] Preferably, the internal cavity of the load-bearing rack and the connector is provided, and the lifting component further includes a cooling pipe installed at the bottom of the inner wall of the processing cavity, with one end of the cooling pipe installed on the lower side of the connector.

[0011] Preferably, the other end of the cooling pipe extends to the outside of the cutting table and is connected to an external cooling device. The cooling device introduces a cooling medium into the cooling pipe, the connector, and the interior of the load-bearing rack to cool the load-bearing rack.

[0012] Preferably, the connector includes a connecting shaft and a loading column movably mounted on the end of the connecting shaft. The loading column is fixedly connected to the bottom of the load-bearing rack, and the cavity is disposed inside the loading column and the load-bearing rack.

[0013] Preferably, the loading column has a ventilation groove inside, which is connected to the corresponding cooling pipe, and the bearing rack has a cooling cavity inside, which is connected to the ventilation groove.

[0014] Preferably, the bearing rack has multiple rectangular grooves inside, which are used to fit the rigid support in the upward path, and multiple triangular teeth are evenly distributed on the top of the bearing rack.

[0015] Preferably, a rotary motor is installed inside the lifting box, and the rotary motor is connected to the corresponding connecting member through an output shaft.

[0016] The beneficial effects of this invention are as follows: 1. The cutting platform for automotive parts described in this invention is driven by a lifting component at the bottom of the processing cavity, causing multiple bearing racks at the bottom of the processing cavity to rise until the tops of the bearing racks and the tops of the multiple supporting racks are on the same horizontal plane. Then, a thin metal plate is placed above the multiple bearing racks and the multiple supporting racks, which is equivalent to a set of bearing racks rising to the position between two adjacent supporting racks. At this time, the position for receiving molten slag becomes the gap between adjacent bearing racks and supporting racks. However, since the thin metal plate has less molten slag, the gap will not become smaller and thus no processing problems will occur. Moreover, because the thin metal plate is supported more densely, there will be no slight elastic deformation or thermal warping problems in the subsequent laser cutting process.

[0017] 2. The cutting platform for automotive parts described in this invention requires the support rack to cooperate with the rising load rack to support the thin metal plate. Therefore, the load rack bears relatively low pressure. At this time, a cooling chamber can be opened inside the load rack. Liquid or gas is circulated and delivered to the cooling pipe, ventilation column groove and the interior of the cooling chamber through an external cooling device for cooling, thereby quickly cooling the load rack, reducing slag sintering and extending the service life of the load rack. Damaged load racks can be removed and replaced by assembling the loading column and connecting shaft. Attached Figure Description

[0021] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0022] Example 1: As Figures 1-4 As shown, an embodiment of the present invention provides a cutting platform for automotive parts, including a cutting table 1 and a processing cavity 2 formed inside the cutting table 1. A multi-axis moving stage 4 is slidably mounted above the cutting table 1, and a laser cutting head 5 is movably mounted above the multi-axis moving stage 4. A support assembly 3 is installed inside the processing cavity 2. The support assembly 3 includes a rigid support member 32 fixedly mounted inside the processing cavity 2 and multiple support racks 31 detachably mounted above the rigid support member 32. The multiple support racks 31 are evenly distributed above the rigid support member 32. Multiple load-bearing racks 6 and multiple lifting components 7 are movably installed at the bottom of the machining cavity 2. The multiple load-bearing racks 6 are lifted and installed inside the machining cavity 2 through the multiple lifting components 7. A set of load-bearing racks 6 is movably installed on the middle vertical surface position of two adjacent support racks 31.

[0023] Specifically, when the initial state of laser cutting automotive parts from a metal plate is required, multiple intact support racks 31 are first evenly installed on a rigid support member 32 to form a support assembly 3. At this time, the spacing between two adjacent support racks 31 is fixed. Then, the metal plate is placed on the support assembly 3, that is, the lower side of the metal plate contacts the top of the multiple support racks 31. At this time, the multiple support racks 31 support the metal plate. The multi-axis moving stage 4 drives the laser cutting head 5 to move along multiple axes, so that the downward-facing laser cutting head 5 performs laser cutting on the metal plate. In the initial state of forming the vehicle parts, the high-temperature slag generated during the cutting process mainly falls into the gap between the two support racks 31 and is collected and processed by the bottom collection device. The spacing between the multiple support racks 31 is fixed. If this spacing is wider, when welding thick metal plates, the large amount of welding slag generated by long-term laser cutting due to the thickness can more easily enter the bottom of the processing cavity 2. In addition, when the metal plate is thick, its heat capacity is large, and thermal warping is not likely to occur. Therefore, the design does not require an overly dense support structure for support, that is, it does not require multiple supports on its bottom side. The dense arrangement of the support racks 31 can lead to problems with low bending stiffness and small heat capacity if the plate to be processed is a thin metal sheet. Therefore, a more dense support structure is needed to prevent slight elastic deformation and thermal warping, which could affect the processing quality of subsequent automotive parts. In this device, when a thin metal sheet needs to be placed above the support assembly 3 for laser cutting, the lifting component 7 at the bottom of the processing cavity 2 drives the multiple support racks 6 at the bottom of the processing cavity 2 to rise until the support racks... The top of the strip 6 is on the same horizontal plane as the top of the multiple support racks 31. Then, the thin metal plate is placed above the multiple load racks 6 and the multiple support racks 31. This is equivalent to a set of load racks 6 rising to the position between two adjacent support racks 31. At this time, the position to accommodate the falling slag becomes the gap between the adjacent load racks 6 and the support racks 31. However, since the thin metal plate has less slag, the gap will not become smaller and thus there will be no processing problems. Moreover, after the thin metal plate is supported more densely, there will be no slight elastic deformation or thermal warping problems in the subsequent laser cutting process.

[0024] like Figures 2-5 As shown, the rigid support member 32 has multiple slots 321 evenly distributed inside, and multiple support racks 31 are inserted and installed inside the corresponding slots 321. Multiple triangular teeth 311 are evenly distributed and installed above the support racks 31.

[0025] Multiple lifting slots 21 are provided at the bottom of the processing cavity 2. Multiple lifting components 7 are installed in the corresponding lifting slots 21. Two lifting components 7 on the same vertical plane are used to control the lifting of a corresponding set of load-bearing racks 6.

[0026] The lifting component 7 includes a lifting box 71 installed inside the lifting groove 21 and a connector 72 installed on the side of the lifting box 71. The end of the connector 72 is connected to the lower side of the load-bearing rack 6.

[0027] Specifically, multiple support racks 31 are inserted into the slots 321 to form a support assembly 3. When a thick metal plate is placed on this support assembly 3, the metal plate can be laser-cut by a multi-axis moving table 4. After multiple cuts, the multiple support racks 31 will be damaged, thus affecting the bearing capacity. At this time, they can be disassembled and replaced. When the bearing rack 6 needs to be raised, multiple lifting boxes 71 are driven to simultaneously drive the connecting parts 72 and the corresponding bearing racks 6 to rise until the tops of the multiple bearing racks 6 are aligned with the tops of the multiple support racks 31 to support the thin metal plate.

[0028] Example 2: Figures 4-7 As shown in the first embodiment, another embodiment of the present invention is as follows: the internal cavity of the rack 6 and the connector 72 is provided, and the lifting component 7 also includes a cooling pipe 73 installed at the bottom of the inner wall of the processing cavity 2, with one end of the cooling pipe 73 installed on the lower side of the connector 72.

[0029] The other end of the cooling pipe 73 extends to the outside of the cutting table 1 and is connected to an external cooling device. The cooling device introduces a cooling medium into the cooling pipe 73, the connector 72 and the interior of the carrying rack 6 to cool the carrying rack 6.

[0030] The connector 72 includes a connecting shaft 721 and a loading column 722 movably mounted on the end of the connecting shaft 721. The loading column 722 is fixedly connected to the bottom of the load rack 6, and the cavity is disposed inside the loading column 722 and the load rack 6.

[0031] The loading column 722 has a ventilation column groove 7221 inside, which is connected to the corresponding cooling pipe 73. The load rack 6 has a cooling chamber 63 inside, which is connected to the ventilation column groove 7221.

[0032] The rack 6 has multiple rectangular slots 62 inside, which are used to fit the rigid support 32 in the upward path. Multiple triangular teeth 61 are evenly distributed on the top of the rack 6.

[0033] A rotary motor is installed inside the lifting box 71, and the rotary motor is connected to the corresponding connecting part 72 through the output shaft.

[0034] Specifically, when the lifting box 71 drives the connecting piece 72 and the supporting rack 6 to rise, the rectangular groove 62 will rise and engage with the corresponding position of the rigid support 32 until the multiple triangular teeth 61 and the multiple triangular teeth 311 are at the same horizontal height. Because the rise of the supporting rack 6 needs to cooperate with the supporting rack 31 to support the thin metal plate, the pressure on the supporting rack 6 is relatively small. At this time, a cooling chamber 63 can be opened inside the supporting rack 6, and cooling pipes 73, ventilation column grooves 7221 and cooling chamber 63 can be cooled by external cooling devices. The cooling system uses circulating liquid or gas to quickly cool the load-bearing rack 6, reducing slag sintering and extending its service life. Damaged load-bearing rack 6 can be removed and replaced by assembling the loading column 722 and connecting shaft 721. If a rotary motor is installed inside the lifting box 71, the load-bearing rack 6 can be rotated when it is at the bottom of the processing chamber 2, so that the multiple triangular teeth 61 face downwards, avoiding the possibility of a small amount of slag remaining on the multiple triangular teeth 61.

[0035] Working principle: When laser cutting automotive parts from a metal plate into their initial state, multiple intact support racks 31 are first evenly installed on a rigid support 32 to form a support assembly 3. At this time, the distance between two adjacent support racks 31 is fixed. Then, the metal plate is placed on the support assembly 3, that is, the lower side of the metal plate contacts the top of the multiple support racks 31. At this time, the multiple support racks 31 support the metal plate. The multi-axis moving stage 4 drives the laser cutting head 5 to move along multiple axes, so that the downward-facing laser cutting head 5 laser cuts the metal plate to form the initial state of the automotive parts. The high-temperature slag generated during this cutting process mainly falls into the gap between the two support racks 31 and is collected by the bottom collection device. In this process, the spacing between the multiple support racks 31 is fixed. If this spacing is wider, when welding thick metal plates, the large amount of welding slag generated during long-term laser cutting due to the thickness can more easily enter the bottom of the processing cavity 2. Furthermore, when the metal plate is thick, its heat capacity is large, making thermal warping less likely. Therefore, the design does not require an overly dense support structure, i.e., the multiple support racks 31 supporting its bottom side do not need to be too densely arranged. However, if the plate to be processed is a thin metal plate, there will be problems with low bending stiffness and small heat capacity. Therefore, a denser support structure is needed to achieve the desired support effect; otherwise, slight elastic deformation and thermal warping may occur, thus affecting the subsequent processing quality of automotive parts. Therefore, in this… In the device, when a thin metal plate needs to be placed above the support assembly 3 for laser cutting, the lifting component 7 at the bottom of the processing cavity 2 drives multiple bearing racks 6 at the bottom of the processing cavity 2 to rise until the tops of the bearing racks 6 and the tops of the multiple support racks 31 are on the same horizontal plane. Then, the thin metal plate is placed above the bearing racks 6 and the support racks 31. This is equivalent to a set of bearing racks 6 rising to the position between two adjacent support racks 31. At this point, the position for receiving the falling slag becomes the gap between adjacent bearing racks 6 and support racks 31. However, because the thin metal plate has less slag, the gap will not become smaller, thus preventing processing problems. Furthermore, because the thin metal plate is supported by a denser network of supports... Subsequently, no slight elastic deformation or thermal warping issues will occur during the subsequent laser cutting process. When the lifting box 71 drives the connecting piece 72 and the supporting rack 6 to rise, the rectangular groove 62 will rise and engage with the corresponding position of the rigid support 32 until multiple triangular teeth 61 and multiple triangular teeth 311 are at the same horizontal height. Because the rise of the supporting rack 6 needs to cooperate with the supporting rack 31 to support the thin metal plate, the pressure on the supporting rack 6 is relatively small. At this time, a cooling chamber 63 can be opened inside the supporting rack 6. Liquid or gas is circulated and delivered to the cooling pipe 73, the ventilation column groove 7221 and the cooling chamber 63 through an external cooling device for cooling, thereby quickly cooling the supporting rack 6 and reducing slag sintering.To extend the service life of the load-bearing rack 6, the damaged load-bearing rack 6 can be disassembled and replaced by assembling the loading column 722 and the connecting shaft 721. If a rotary motor is installed inside the lifting box 71, when the load-bearing rack 6 is at the bottom of the processing chamber 2, the rotary motor can drive the load-bearing rack 6 to rotate, causing the multiple triangular teeth 61 to face downwards, thus preventing a small amount of molten slag from potentially remaining on the multiple triangular teeth 61.
