Technical Field
[0001] This utility model belongs to the field of laser cutting machine technology, and in particular relates to a high-precision laser cutting machine bed. Background Technology
[0002] A laser cutting machine is a machine that takes a laser emitted from a laser source, focuses it into a high-power-density laser beam through an optical path system, and then uses the laser beam to irradiate the surface of the workpiece, causing the workpiece to reach its melting or boiling point, thereby completing the cutting process.
[0003] Patent CN220659636U discloses a bed and a laser cutting machine. After prolonged use, the lubricating oil on the guide rail of the laser cutting machine will be gradually consumed due to long-term friction, resulting in insufficient lubrication of the guide rail. This causes uneven resistance when the laser cutting head moves, resulting in jamming and preventing it from moving strictly according to the preset path and speed. Ultimately, this causes the cutting position to deviate from the preset coordinates, reducing the cutting accuracy.
[0004] Therefore, it is necessary to improve the existing laser cutting machine bed technology. Utility Model Content
[0005] The purpose of this invention is to overcome the defects in the existing technology and provide a high-precision laser cutting machine bed to improve the cutting accuracy of the laser cutting machine.

[0017] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.
[0018] The terms "top surface," "bottom surface," and "full surface" refer to the normal operating state of the laser cutting machine bed and are used only for the convenience of describing this utility model and simplifying the description. They are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this utility model.
[0019] like Figure 1-5 As shown, a high-precision laser cutting machine bed includes a main body 1, a guide rail 2 on the main body 1, a sliding seat 3 on the guide rail 2, the sliding seat 3 having a U-shaped groove structure and being semi-enclosed on the guide rail 2, the inner wall of the sliding seat 3 slidingly engaging with the outer wall of the guide rail 2; the sliding seat 3 having an oil cavity communicating with the inner side of the U-shaped opening, the inside of the oil cavity being filled with a sponge block 35.
[0020] The laser cutting machine bed is equipped with two parallel guide rails 2, each with a sliding seat 3. The laser cutting head is mounted between the two sliding seats 3, and the sliding seats 3 slide along the guide rails 2 to support the laser cutting head's movement. The oil chamber stores lubricating oil, which is released between the guide rails 2 and the sliding seats 3 as the sliding seats 3 slide along the guide rails 2. This lubrication reduces the relative sliding resistance between the two, alleviates the jamming of the sliding seats 3, and ultimately improves the cutting accuracy of the laser cutting machine. The sponge block 35 can absorb the lubricating oil in the oil chamber and release it slowly, avoiding excessive lubrication or subsequent oil shortage caused by a large amount of oil released at once. This provides long-term lubrication between the guide rails 2 and the sliding seats 3, ensuring that the laser cutting machine can perform high-precision cutting for extended periods.
[0021] Further improvements include, for example Figure 3 and 4As shown, at least one end face of the sliding seat 3 is provided with a recess 302, and a sealing gasket 31 covering the recess 302 is also provided on the end face of the sliding seat 3. The sealing gasket 31 is sealed to both the sliding seat 3 and the guide rail 2. The oil cavity is formed by the inner wall of the recess 302, the outer wall of the guide rail 2 and the sealing gasket 31.
[0022] Specifically, such as Figure 4 As shown, the oil cavity surrounds the top surface and both sides of the guide rail 2. This allows the released lubricating oil to form a large-area oil film between the contact surfaces of the guide rail 2 and the sliding seat 3. The sponge block 35 further helps to evenly distribute the absorbed lubricating oil, ensuring a uniform oil film and improving the lubrication effect between the two, thus enhancing the cutting accuracy of the laser cutting machine. The sealing gasket 31 is a rubber gasket. The opening and closing of the recessed portion 302 can be achieved by removing and installing the sealing gasket 31, facilitating maintenance of the sliding seat 3 and the sponge block 35. Simultaneously, the sliding seal between the sealing gasket 31 and the guide rail 2 prevents leakage of lubricating oil inside the oil cavity. Furthermore, the sealing... The pad 31 can clean the guide rail 2 to a certain extent, reducing the amount of impurities on the guide rail 2 entering the contact surface between the guide rail 2 and the sliding seat 3, thereby improving the smoothness of sliding between the two and reducing wear between them. Since the sliding seat 3 can slide back and forth along the guide rail 2, recesses 302 and sealing pads 31 can be provided at both ends of the sliding seat 3, so that the sealing pads 31 can clean the guide rail 2 to a certain extent when the sliding seat 3 slides in different directions. During the sliding process of the sliding seat 3, the sponge block 35 can also clean the impurities on the guide rail 2 to a certain extent, further improving the smoothness of sliding between the sliding seat 3 and the guide rail 2.
[0023] Further improvements include, for example Figure 4 As shown, an oil guide groove 304 communicating with the oil cavity is provided on the inner wall of the sliding seat 3. The oil groove 304 allows lubricating oil to flow inside, so that the lubricating oil can be better delivered to the contact surface between the guide rail 2 and the sliding seat 3, thereby improving the lubrication effect between the two, reducing the jerking of the sliding seat 3, and improving the cutting accuracy of the laser cutting machine.
[0024] Further improvements include, for example Figure 3 and 4 As shown, the sliding seat 3 has an oil injection hole 305 that connects the inside and outside of the oil cavity. A sealing bolt 33 is threadedly connected to the oil injection hole 305. A sealing ring is provided on the bolt head of the sealing bolt 33. The sealing ring fills the gap between the sealing bolt 33 and the sliding seat 3 to achieve a sealing effect. Lubricating oil can be added to the inside of the oil cavity through the oil injection hole 305 to maintain long-term lubrication between the guide rail 2 and the sliding seat 3 and improve the cutting accuracy of the laser cutting machine.
[0025] Further improvements include, for example Figure 4As shown, a pin 303 is provided on the inner wall of the recess 302. Multiple pins 303 are provided. By inserting the pins 303 into the interior of the sponge block 35, the sponge block 35 can be supported, so that the sponge block 35 can better fill the entire oil cavity. Thus, the lubricating oil is delivered to all parts of the oil cavity through the sponge block 35, thereby improving the uniformity of the lubricating oil applied to the guide rail 2.
[0026] Further improvements include, for example Figure 6 As shown, the sealing gasket 31 has a U-shaped groove structure and is semi-enclosed on the guide rail 2. A through groove 311 is formed on the inner wall of the sealing gasket 31, and the extension direction of the through groove 311 is perpendicular to the extension direction of the guide rail 2. The U-shaped groove structure of the sealing gasket 31 can better fit the shape of the guide rail 2 and improve the sealing effect between the two. The channel 311 is used to collect impurities that enter between the mating surfaces of the sealing gasket 31 and the guide rail 2 and discharge the impurities from both ends of the through groove 311. In this way, while maintaining the sealing effect between the sealing gasket 31 and the guide rail 2, the wear between the two can be reduced, thereby reducing the equipment failure rate and improving the cutting accuracy of the equipment.
[0027] Further improvements include, for example Figure 3 and 7 As shown, a U-shaped mounting base 322 is provided on the side of the sealing gasket 31 opposite to the sliding seat 3. Brush bristles 32 are provided on the inner wall of the mounting base 322, and these bristles 32 are in contact with the outer wall of the guide rail 2. With the brush bristles 32 on the inner wall of the U-shaped opening of the mounting base 322, when the sliding seat 3 slides along the guide rail 2, the guide rail 2 passes through the U-shaped opening of the mounting base 322. At this time, the brush bristles 32 can pre-remove large particles and metal debris from the guide rail 2, thereby reducing the cleaning pressure on the sealing gasket 31 and the sponge block 35, maintaining the cleanliness between the guide rail 2 and the sliding seat 3, reducing the jamming of the sliding seat 3, improving the cutting accuracy of the laser cutting machine, and extending the service life of the equipment.
[0028] Further improvements include, for example Figure 3-7 As shown, the sliding seat 3 has a threaded hole 301, the sealing gasket 31 has a mounting hole 312, and the mounting seat 322 has a second countersunk hole 321. A second bolt 34 is threadedly connected to the threaded hole 301, and the second bolt 34 passes through the second countersunk hole 321 and the mounting hole 312 in sequence. The second bolt 34 improves the ease of disassembly and assembly between the sealing gasket 31 and the mounting seat 322 and the sliding seat 3, thereby improving the ease of replacement and maintenance of various components and the ease of use of the laser cutting machine bed.
[0029] Further improvements include, for example Figure 1As shown, the guide rail 2 has a first countersunk hole 201. A first bolt 202, threadedly connected to the main body 1, is installed inside the first countersunk hole 201. A sealing plug 203 is also installed inside the first countersunk hole 201, with its side flush with the outer wall of the guide rail 2. The sealing plug 203 is a polytetrafluoroethylene (PTFE) sealing block. The interference fit between the sealing plug 203 and the first countersunk hole 201 enhances the sealing effect, thus reducing the amount of lubricating oil lost from the first countersunk hole 201 during the sliding of the sliding seat 3, thereby prolonging the lubrication effect on the sliding seat 3. Furthermore, the sealing plug 203 makes the surface of the guide rail 2 smoother, improving the cleaning effect of the guide rail 2. The lubricating properties of PTFE further reduce the jamming during sliding between the sliding seat 3 and the guide rail 2, further improving the cutting accuracy of the laser cutting machine.
