Description

Technical Field

[0001] This utility model relates to the technical field of marble processing equipment, and more specifically, to a marble cutting platform. Background Technology

[0002] In the marble processing industry, the mainstream cutting technologies currently include mechanical sawing, waterjet cutting, and traditional laser cutting. Mechanical sawing typically uses diamond blades to cut marble slabs through physical contact and is widely used in architectural decoration and sculpture processing. Waterjet cutting uses high-pressure water jets mixed with abrasive particles for non-contact cutting and is often used for processing complex patterns. Traditional laser cutting uses CO2 lasers or fiber lasers to achieve cutting through surface ablation. These technologies each have their applications in marble processing, but all have significant limitations.

[0003] The shortcomings of existing technology:

[0004] 1. Mechanical sawing:

[0005] Material waste: Micro-cracks and edge chipping are generated during the saw blade cutting process, which damages the marble surface and results in a material waste rate of 10% to 15%.

[0006] Machining accuracy: Due to the physical characteristics of the cutting tools, it is difficult to achieve fine cutting of less than 1 mm, which cannot meet the requirements of high-precision decoration.

[0007] Post-processing requirements: Polishing and other processes are required after cutting, which increases labor and time costs and reduces efficiency.

[0008] 2. Waterjet cutting:

[0009] Resource consumption: It consumes hundreds of liters of water and a large amount of abrasive per hour, resulting in high operating costs and water pollution pressure on the environment.

[0010] Processing speed: The cutting speed is usually 0.1-0.5 m / s, which is far lower than the efficiency of laser technology and is difficult to adapt to mass production.

[0011] Surface quality: Abrasive particles may embed in the marble surface, affecting the appearance quality and requiring additional cleaning procedures.

[0012] In summary, existing technologies have shortcomings in terms of precision, efficiency, material protection, and functionality, and lack effective solutions. Therefore, there is an urgent need for a high-precision, low-loss device to improve marble processing capabilities. Utility Model Content

[0013] To solve at least one of the above problems, the present invention first provides a marble cutting platform, including a first worktable, two first guide rails symmetrically fixedly connected to the upper end of the first worktable, a first slider slidably disposed on the surface of each of the two first guide rails, a first coreless linear motor fixedly connected to the upper end of the first worktable, and a first slide block fixedly connected to the upper end of the first coreless linear motor.

[0014] The upper end of the first slide is fixedly connected to a second worktable. The upper end of the second worktable is symmetrically fixedly connected to two second guide rails. The surfaces of the two second guide rails are slidably provided with second sliders. The upper end of the second worktable is fixedly connected to a second coreless linear motor. The upper end of the second coreless linear motor is fixedly connected to a second slide. The upper end of the second slide is fixedly connected to a DD motor. The output end of the DD motor is fixedly connected to a product mounting plate.

[0015] Optionally, the upper ends of both first sliders are fixedly connected to the lower end of the first slide block.

[0016] Optionally, a first base frame is fixedly connected to the side wall of the first workbench.

[0017] Optionally, the upper ends of both second sliders are fixedly connected to the lower end of the second slide block.

[0018] Optionally, a second base frame is fixedly connected to the side wall of the second workbench.

[0019] Optionally, a grating encoder is provided at the lower end of the first slide.

[0020] Optionally, the first and second work surfaces are made of Jinan Green marble with a surface flatness of less than 2 micrometers.

[0021] Optionally, the first basic frame is made of high-strength steel or aluminum alloy, and its surface is coated with an anti-corrosion coating.

[0022] Optionally, the second basic frame is made of high-strength steel or aluminum alloy, and its surface is coated with an anti-corrosion coating.

[0023] Compared to existing technologies, this utility model presents a marble cutting platform that achieves a cutting accuracy of ±0.5 micrometers through a coreless linear motor, realizing sub-micrometer positioning, which is 50 times higher than traditional mechanical sawing (±1 mm). This solves the problem of insufficient accuracy in traditional mechanical systems, meets the needs of high-end decoration, and the coreless linear motor has a speed of 2 m / s and an acceleration of 3G, which shortens the processing time by 30% compared to waterjet cutting (0.5 m / s), thus improving production efficiency. Furthermore, the high-torque DD motor achieves the synergy of rotation and linear motion, breaking through the limitations of single-axis cutting. Attached Figure Description

[0030] To make the above-mentioned objectives, features and advantages of this utility model more readily understood, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0031] This utility model embodiment provides a marble cutting platform, combined with Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the worktable includes a first worktable surface 1, which is made of marble (Jinan Green) with a surface flatness of less than 2 micrometers. Two first guide rails 2 are symmetrically fixedly connected to the upper end of the first worktable surface 1. The first guide rails 2 are linear guide rails and adopt a ball bearing slider design to ensure low friction and high-precision movement. The surfaces of the two first guide rails 2 are slidably equipped with first sliders 3. The sliding of the two first sliders 3 on the surfaces of the first guide rails 2 facilitates the sliding of the first slide block 5. The first guide rails 2 and the first sliders 3 guide the first slide block 5 when it moves, preventing the first slide block 5 from deviating and affecting the cutting quality.

[0032] A first coreless linear motor 4 is fixedly connected to the upper end of the first worktable 1. The first coreless linear motor 4 has a rated thrust of 200 Newtons, a maximum speed of 2 meters per second, and a positioning accuracy of ±0.5 micrometers. A first slide block 5 is fixedly connected to the upper end of the first coreless linear motor 4. A grating encoder 15 is installed at the lower end of the first slide block 5. The upper ends of both first sliders 3 are fixedly connected to the lower ends of the first slide block 5. By controlling the start of the first coreless linear motor 4, the first slide block 5 is moved, and the first slide block 5 moves the first slider 3. The sliding block 3 on the first guide rail 2 prevents the first slide block 5 from shifting, thereby enabling the first slide block 5 to move in the X direction, which in turn drives the product mounting plate 14 to move in the X-axis direction (speed up to 2 m / s). The parameters of the first coreless linear motor 4 are set as follows: speed 2 m / s, acceleration 30G. The first slide block 5 moves 1 meter along the first guide rail 2 in 0.5 seconds. The first coreless linear motor 4 controls the movement of the first slide block 5 through a servo feedback system (resolution 0.1 micrometers) to ensure the consistency of the cutting path.

[0033] The first worktable 1 is fixedly connected to the side wall of the first base frame 1. The first base frame 11 is made of high-strength steel or aluminum alloy and has an anti-corrosion coating on its surface. The two sides of the first base frame 11 are fixed to the first worktable 1 by multiple sets of fixing bolts. The top of the first base frame 11 passes through the first slide block 5. The first base frame 11 can prevent debris from falling onto the first guide rail 2 and will not affect the movement of the first slider 3 and the first slide block 5.

[0034] The upper end of the first slide block 5 is fixedly connected to the second worktable surface 6. The material of the second worktable surface 6 is marble Jinan Green, and the surface flatness is less than 2 micrometers. The upper end of the second worktable surface 6 is symmetrically fixedly connected to two second guide rails 7. The second guide rails 7 are linear guide rails and adopt a ball slider design to ensure low friction and high precision movement. The surfaces of the two second guide rails 7 are slidably equipped with second sliders 8. The two second sliders 8 slid on the surfaces of the second guide rails 7 to facilitate the sliding of the second slide block 10. The second guide rails 7 and second sliders 8 guide the second slide block 10 when it moves, preventing the second slide block 10 from deviating and affecting the cutting quality.

[0035] A second coreless linear motor 9 is fixedly connected to the upper end of the second worktable 6. The second coreless linear motor 9 has a rated thrust of 200 Newtons, a maximum speed of 2 meters per second, and a positioning accuracy of ±0.5 micrometers. A second slide 10 is fixedly connected to the upper end of the second coreless linear motor 9. A DD motor 13 is fixedly connected to the upper end of the second slide 10. The DD motor 13 is fixed to the second slide 10 by fixing bolts. The motor has a rated torque of 50 N·m, a maximum speed of 300 rpm, and a positioning accuracy of ±1.5 Arcsec degrees. It is used for multi-axis rotation adjustment of the laser head or workpiece. A product mounting plate 14 is fixedly connected to the output end of the DD motor 13. The product mounting plate 14 facilitates product installation. By controlling the start of the DD motor 13, the product mounting plate 14 can be rotated, thereby rotating the product and achieving circular motion. The angle adjustment of the workpiece, combined with linear motion, completes the cutting of complex patterns. The upper ends of the two second sliders 8 are fixedly connected to the lower ends of the second slide block 10. By controlling the start of the second coreless linear motor 9, the second slide block 10 is moved, and the second slide block 10 moves the second sliders 8. The sliding of the second sliders 8 on the second guide rail 7 can prevent the second slide block 10 from deviating, thereby enabling the second slide block 10 to move in the Y-axis direction, which in turn enables the product mounting plate 14 to move in the Y-axis direction (speed up to 2 m / s). The parameters of the second coreless linear motor 9 are set as follows: speed 2 m / s, acceleration 30G. The second slide block 10 moves 1 meter along the second guide rail 7, and the completion time is 0.5 seconds. The second coreless linear motor 9 controls the movement of the second slide block 10 through a servo feedback system (resolution 0.1 micrometers) to ensure the consistency of the cutting path.

[0036] The second worktable 6 is fixedly connected to the side wall of the second base frame 12. The second base frame 12 is made of high-strength steel or aluminum alloy and has an anti-corrosion coating on its surface. The two sides of the second base frame 12 are fixed to the second worktable 6 by multiple sets of fixing bolts. The top of the second base frame 12 passes through the second slide block 10. The second base frame 12 can prevent debris from falling onto the second guide rail 7 and will not affect the movement of the second slider 8 and the second slide block 10.

[0037] Working principle: The first coreless linear motor 4 drives the first slide 5 to move in the X-axis direction (speed up to 2 m / s). When the first slide 5 moves, it drives the first slider 3 to slide on the first guide rail 2. The second coreless linear motor 9 drives the second slide 10 to move in the Y-axis direction (speed up to 2 m / s). When the second slide 10 moves, it drives the second slider 8 to slide on the second guide rail 7. The DD motor 13 drives the product to be cut on the product mounting plate 14 mounted on the DD axis to achieve circumferential motion.

[0038] Operating principle of upper and lower shafts: Stable thrust is provided by a coreless motor, low friction is generated by a high-precision linear guide, and linear motion is achieved by reading the position through an optical encoder 15.

[0039] The operating principle of DD motor 13: It achieves circular motion by using the torque parameter of the torque motor, supported by the cross roller bearing, and reading the position through the grating encoder.
