Description

Technical Field

[0001] This invention relates to the field of plasma cutting technology, specifically to an intelligent cutting device for the production of automotive parts. Background Technology

[0002] The gantry plasma cutting system is a high-efficiency cutting device designed specifically for medium and thick metal plates. With "gantry frame + plasma arc technology" as its core, it combines large-span processing capability with cost advantages and is widely used in the processing of steel structures, automotive parts, heavy machinery and other fields.

[0003] Existing gantry plasma cutting equipment generates a large amount of sparks and metallic fumes during the cutting and grinding of automotive parts, causing serious pollution to the production site environment. The fumes pollute the atmosphere and harm the physical and mental health of production workers. It is particularly necessary to remove dust from the sparks and metallic fumes generated during the cutting and grinding process to prevent the fumes from harming workers and polluting the environment. Furthermore, for the cutting of automotive parts, most of the cutting areas are curved, and care must be taken to pay attention to the operating angle when spraying for cooling and fume extraction to avoid affecting the cutting results.

[0004] To address the aforementioned issues, innovative design based on existing methods is urgently needed. Summary of the Invention

[0005] The purpose of this invention is to provide an intelligent cutting device for the production of automotive parts, in order to solve the problems mentioned in the background. The technical solution of this invention addresses the problem that the existing technical solutions are too simplistic and provides a solution that is significantly different from the existing technology.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an intelligent cutting device for automotive parts production, comprising a worktable, a gantry frame at the upper end of the worktable, a robotic arm at the top of the gantry frame, a cooling assembly at the end of the robotic arm, a cutting head connected to the robotic arm within the cooling assembly, a dust removal assembly at the lower end of the cooling assembly, a rotating assembly at the middle of the cooling and dust removal assemblies, angle adjustment assemblies at the lower ends of both the cooling and dust removal assemblies, a sleeve at the lower end of the dust removal assembly, a height adjustment assembly inside the sleeve, a water tank in the cooling assembly, a water tank fixedly installed at the output end of the robotic arm, the water tank connected to an external delivery pump via a pipeline, a thick water pipe penetrating the lower end of the water tank, a thin water pipe vertically sliding at the lower end of the thick water pipe, a water spray head rotatably mounted at the lower end of the thin water pipe, and a flexible hose connecting the thin water pipe and the water spray head.

[0007] Preferably, the dust removal assembly includes a dust removal box, which is fixedly installed at the lower end of the water storage tank. The dust removal box is connected to an external fan through a pipeline. A coarse air duct is provided through the lower end of the dust removal box. A thin air duct is vertically limited and slidable at the lower end of the coarse air duct. A suction head is rotatably installed at the lower end of the thin air duct. A flexible hose is provided between the thin air duct and the suction head.

[0008] Preferably, the rotating assembly includes a motor, which is fixedly mounted on the outer wall of the water storage tank. The output end of the motor is provided with a bevel gear one, which meshes with a bevel gear two. A turntable is rotatably and sealed in the lower inner wall of both the water storage tank and the dust removal box. A connecting column one is fixed between the two turntables. The connecting column one passes through the turntable on the lower inner wall of the water storage tank, and the upper end of the connecting column one is fixedly connected to the bevel gear two.

[0009] Preferably, the coarse air duct is fixedly inserted through the turntable inside the dust collector, and the coarse water duct is inserted through both the upper and lower turntables, and the coarse water duct is fixedly connected to both the upper and lower turntables.

[0010] Preferably, the angle adjustment component includes a rack, which is fixedly installed at the lower end of the coarse air duct and the coarse water duct. A gear is engaged on one side of the rack, and a connecting shaft is fixed in the middle of the gear. A connecting strip is provided in the middle of the connecting shaft. The upper end of the connecting strip is fixedly connected to the fine air duct and the fine water duct. The connecting shaft rotates within the connecting strip. The front end of the connecting shaft is fixedly connected to the vacuum head and the water spray head.

[0011] Preferably, the height adjustment assembly includes an electric push rod, which is fixedly installed on the outer wall of the sleeve. A connecting strip two is fixed to the output end of the electric push rod, and an abutment ring is fixed to the front end of the connecting strip two. Abutment rings are provided at both the thin water pipe and the thin air pipe. A connecting post two is fixed between the two abutment rings. An abutment joint is abutted above the abutment rings. A spring is fixed to the rear end of the abutment joint. The rear end of the spring is fixedly connected to the inner wall of the cavity of the sleeve. An abutment block is abutted at the front end of the abutment joint. The abutment block is fixed to the outside of the thin air pipe and the thin water pipe.

[0012] Preferably, the abutment and the spring are distributed at equal angles, the front end of the abutment has a hemispherical structure, and the lower end of the abutment is designed as an inclined structure.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] This invention utilizes an independent cooling component. Coolant stored in a water tank is precisely delivered to the spray nozzles via water pipes, directly acting on the cutting area and cutting head. This quickly removes the high temperatures generated during cutting, preventing issues such as material deformation and reduced cutting accuracy caused by high temperatures. It also reduces wear and tear on cutting components, significantly extending equipment lifespan and ensuring long-term stable operation. Simultaneously, an independent dust removal component generates suction in the dust collection box, efficiently collecting metal fumes generated during cutting through ducts and suction heads. This significantly reduces the diffusion of fumes in the working environment, minimizing atmospheric pollution and preventing workers from inhaling the fumes. This approach protects the physical and mental health of operators from the source, meeting the requirements of green production and occupational health.

[0015] The gear transmission drives the water pipes and air pipes to rotate synchronously, expanding the cooling and dust removal coverage. The angle adjustment component uses the meshing of rack and gear to flexibly adjust the angle of the water spray head and dust suction head, improving the dust suction and spraying effect. The height adjustment component controls the distance between the working part and the cutting surface through the cooperation of the abutment joint and the abutment block, adapting to cutting operations of different curvatures and improving the versatility and operational flexibility of the device.

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Please see Figures 1-8 This invention provides a technical solution: an intelligent cutting device for automotive parts production, comprising a workbench 1, a gantry frame 2 at the upper end of the workbench 1, a robotic arm 3 at the top of the gantry frame 2, a cooling assembly 4 at the end of the robotic arm 3, a cutting head connected to the robotic arm 3 inside the cooling assembly 4, a dust removal assembly 5 at the lower end of the cooling assembly 4, a rotating assembly 6 at the middle of the cooling assembly 4 and the dust removal assembly 5, angle adjustment assemblies 7 at the lower ends of both the cooling assembly 4 and the dust removal assembly 5, a sleeve 8 at the lower end of the dust removal assembly 5, a height adjustment assembly 9 inside the sleeve 8, a water storage tank 41 fixedly installed at the output end of the robotic arm 3, the water storage tank 41 connected to an external delivery pump via a pipeline, a thick water pipe 42 penetrating the lower end of the water storage tank 41, a thin water pipe 43 vertically sliding at the lower end of the thick water pipe 42, a water spray head 44 rotatably mounted at the lower end of the thin water pipe 43, and a hose connecting the thin water pipe 43 and the water spray head 44.

[0027] Please see Figure 3 The dust removal assembly 5 includes a dust removal box 51, which is fixedly installed at the lower end of the water storage tank 41. The dust removal box 51 is connected to an external fan through a pipe. A thick air duct 52 is provided through the lower end of the dust removal box 51. A thin air duct 53 is vertically limited and slidable at the lower end of the thick air duct 52. A suction head 54 is rotatably installed at the lower end of the thin air duct 53. A flexible hose is provided between the thin air duct 53 and the suction head 54.

[0028] In one embodiment of the present invention, the coolant in the water storage tank 41 is transported to the spray head 44 through the coarse water pipe 42 and the fine water pipe 43 to spray and cool the cutting area and the cutting head. At the same time, the dust collection box 51 generates suction, and the metal char fumes generated during cutting are collected by the dust collection head 54 through the coarse air pipe 52 and the fine air pipe 53.

[0029] Please see Figure 4 The rotating assembly 6 includes a motor 61, which is fixedly installed on the outer wall of the water storage tank 41. The output end of the motor 61 is provided with a bevel gear 62, which meshes with a bevel gear 63. A turntable 64 is sealed and rotatably installed in the lower inner wall of both the water storage tank 41 and the dust removal box 51. A connecting column 65 is fixed between the two turntables 64. The connecting column 65 passes through the turntables 64 on the lower inner wall of the water storage tank 41, and the upper end of the connecting column 65 is fixedly connected to the bevel gear 63.

[0030] A thick air duct 52 is fixedly inserted through the turntable 64 inside the dust collector 51, and a thick water duct 42 is inserted through the upper and lower turntables 64. The thick water duct 42 is fixedly connected to the upper and lower turntables 64.

[0031] In one embodiment of the present invention, the motor 61 on the outer wall of the water storage tank 41 drives the first bevel gear 62 to rotate, which in turn drives the meshing second bevel gear 63 and the connected turntable 64 to rotate. The connecting column 65 makes the water storage tank 41 and the turntable 64 in the dust removal box 51 rotate synchronously. Since the coarse water pipe 42 and the coarse air pipe 52 are respectively fixed to the corresponding turntable 64, they synchronously drive the water spray head 44 and the dust suction head 54 to rotate to expand the cooling and dust removal range.

[0032] Please see Figure 5 The angle adjustment component 7 includes a rack 71, which is fixedly installed at the lower end of the coarse air duct 52 and the coarse water duct 42. A gear 72 meshes on one side of the rack 71, and a connecting shaft 73 is fixed in the middle of the gear 72. A connecting strip 74 is provided in the middle of the connecting shaft 73. The upper end of the connecting strip 74 is fixedly connected to the fine air duct 53 and the fine water duct 43. The connecting shaft 73 rotates in the connecting strip 74, and the front end of the connecting shaft 73 is fixedly connected to the vacuum head 54 and the water spray head 44.

[0033] In one embodiment of the present invention, the coarse water pipe 42 and coarse air pipe 52 rotate synchronously with the turntable 64, and the abutting block 97 rotates with it, intermittently abutting the abutting head 95, thereby driving the rack 71 to move up and down. The rack 71 drives the meshing gear 72, causing the connecting shaft 73 to rotate within the connecting bar 74, adjusting the angle between the water spray head 44 and the dust suction head 54, so that they can perform circumferential and reciprocating swing operations.

[0034] Please see Figure 7The height adjustment component 9 includes an electric push rod 91, which is fixedly installed on the outer wall of the sleeve 8. A connecting strip 92 is fixed to the output end of the electric push rod 91. An abutment ring 93 is fixed to the front end of the connecting strip 92. An abutment ring 93 is provided at both the thin water pipe 43 and the thin air pipe 53. A connecting post 94 is fixed between the two abutment rings 93. An abutment joint 95 is abutted above the abutment ring 93. A spring 96 is fixed to the rear end of the abutment joint 95. The rear end of the spring 96 is fixedly connected to the inner wall of the cavity of the sleeve 8. An abutment block 97 is abutted at the front end of the abutment joint 95. The abutment block 97 is fixed to the outside of the thin air pipe 53 and the thin water pipe 43.

[0035] The abutment 95 and spring 96 are distributed at equal angles. The front end of the abutment 95 has a hemispherical structure, and the lower end of the abutment 95 is designed as an inclined structure.

[0036] In one embodiment of the present invention, the connecting strip 92 is pushed by the electric push rod 91 on the outer wall of the sleeve 8, which causes the abutment ring 93 to abut against the abutment head 95. Combined with the elastic force of the spring 96, the height of the thin water pipe 43 and the thin air pipe 53 is adjusted to ensure that the water spray head 44 and the dust suction head 54 maintain a suitable distance from the cutting surface, thus ensuring that the cutting operation is efficient and environmentally friendly.

[0037] Working principle: During operation, the gantry 2 and robotic arm 3 work together with the cutting head to perform plasma cutting on the workpiece. The cutting head passes through the water tank 41 and the dust collection box 51 and is connected to the external circuit. The coolant in the water tank 41 is transported to the spray head 44 through the coarse water pipe 42 and the fine water pipe 43 to spray and cool the cutting area and the cutting head. At the same time, the dust collection box 51 generates suction, and the metal fumes generated during cutting are collected by the suction head 54 through the coarse air pipe 52 and the fine air pipe 53. The motor 61 on the outer wall of the rear end of the water tank 41 drives the first bevel gear 62 to rotate, which in turn drives the meshing second bevel gear 63 and the connected turntable 64 to rotate. The connecting column 65 causes the water tank 41 and the turntable 64 in the dust collector 51 to rotate synchronously. Since the thick water pipe 42 and the thick air pipe 52 are fixed to the corresponding turntable 64, they synchronously drive the spray head 44 and the dust suction head 54 to rotate to expand the cooling and dust removal range. As the thick water pipe 42 and the thick air pipe 52 rotate synchronously with the turntable 64, the abutting block 97 rotates with it and intermittently abuts against the abutting head 95, thereby driving the rack 71 to move up and down. The rack 71 drives the meshing gear 72, causing the connecting shaft 73 to rotate in the connecting bar 74, adjusting the angle of the spray head 44 and the dust suction head 54, so that they can perform circumferential and reciprocating swing operations.

[0038] When cutting workpiece areas with different curvatures, the electric push rod 91 on the outer wall of the sleeve 8 pushes the connecting strip 92, causing the abutment ring 93 to abut against the abutment joint 95. Combined with the elastic force of the spring 96, the height of the thin water pipe 43 and the thin air pipe 53 is adjusted to ensure that the water spray head 44 and the dust suction head 54 maintain a suitable distance from the cutting surface, ensuring the high efficiency and environmental protection of the cutting operation.

[0039] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
