Abstract
Description
Technical Field
[0001] This utility model belongs to the field of pipe cutting equipment, specifically relating to an adjustable distance support plate device for laser cutting. Background Technology
[0002] In laser cutting, the support plate is a crucial component that supports the material to be cut and ensures stable cutting operations. Its structural design directly affects cutting accuracy, material utilization, and production efficiency. Currently, the core structure of laser cutting support plates widely used in the industry is a long strip of steel plate. To reduce the obstruction of the laser cutting path by the support plate and to provide stable support for the material, technicians typically machine one long edge of the steel plate into a serrated shape. During actual assembly, several such steel plates need to be arranged side-by-side according to a pre-set pattern, allowing the material to be cut to be stably placed on the serrated protrusions of each plate. The multi-point support of the serrations achieves the positioning of the material.
[0003] However, this structure has a significant inherent drawback: once the steel plates are installed using bolts, welding, or other fixing methods, the spacing between adjacent steel plates cannot be adjusted. This fixed spacing design has gradually revealed many problems in practical applications. From the perspective of plate adaptability, the size and thickness of the plates to be cut in laser cutting scenarios vary considerably, making it difficult for the fixed spacing to meet diverse support needs. For small-sized plates, excessive spacing leads to a lack of support at the plate edges, making them prone to shifting during cutting and directly affecting cutting accuracy. For large-sized plates, insufficient spacing causes the support plate to excessively obstruct the cutting area, potentially resulting in an incomplete cutting path, increased waste, and reduced material utilization.
[0004] From the perspective of chip removal during the cutting process, the metal chips generated by laser cutting need to be discharged through the gaps between the steel plates. A fixed gap cannot meet the chip removal requirements of plates with different thicknesses. When cutting thin plates, although an excessively large gap can allow chips to be discharged quickly, it will weaken the stability of the plate. When cutting thick plates, an excessively small gap is prone to chip accumulation. Chips that are not discharged in time will not only scratch the surface of the plate, but also cause heat accumulation in the cutting area, interfering with the thermal processing effect of the laser and further reducing the cutting quality.
[0005] From the perspective of production efficiency and equipment versatility, the fixed spacing design greatly limits process flexibility. Modern manufacturing often requires switching between cutting tasks for different specifications of sheet metal. Each time a switch is made, companies need to disassemble the original pallet and replace it with a new pallet with the appropriate spacing. This not only consumes a lot of downtime, but also requires stockpiling spare pallets with various spacings, increasing equipment maintenance costs and inventory pressure. It is difficult to meet the flexible needs of multi-variety, small-batch production, becoming an important factor restricting the efficient application of laser cutting technology.

[0023] Figure 3 This is a schematic diagram of the slat structure in this embodiment;
[0024] The telescopic linkage mechanism includes 1, a connecting rod 1a, a trolley 2, a roller 2a, a support part 3, a slat 4, a through hole 4a, a serration 4b, a second slot 4c, a slide bar 5, and a base 6. Detailed Implementation
[0025] like Figure 1-3 As shown, this embodiment includes a telescopic linkage mechanism 1, a trolley 2, a support 3, a slat 4, and a slide bar 5.
[0026] The telescopic linkage mechanism 1 specifically adopts a scissor-type telescopic linkage mechanism that extends and retracts in the horizontal direction. The middle, upper, and lower parts of the two links 1a are all hinged through hinge shafts. In this embodiment, the link 1a is in the shape of a long strip plate; in other embodiments, the link 1a may also be made of tubing.
[0027] In this embodiment, the telescopic linkage mechanism 1 is provided in two sets, which are arranged in parallel and symmetrically. The hinge shafts of the two connecting rods 1a below each set of telescopic linkage mechanism 1 are also connected to the upper end of the trolley 2.
[0028] The lower end of the trolley 2 is equipped with two rollers 2a, which are located on both sides of the hinge shaft below the telescopic linkage mechanism 1. With this configuration, the telescopic linkage mechanism 1 can slide smoothly during extension and retraction without tipping over.
[0029] In other embodiments, the number of rolling tracks at the lower end of the trolley 2 can also be set to other numbers, such as four. Specifically, they are arranged in a rectangle with the center of the hinge shaft below the telescopic linkage mechanism 1 as the center.
[0030] The lower end of the support part 3 is connected to the upper hinge shaft of the telescopic linkage mechanism 1, and the upper end of the support part 3 is used to fix the strip 4.
[0031] The strip 4 is a long strip, and one of its long edges is serrated 4b, which is used to support the workpiece to be cut.
[0032] Both ends of the slat 4 are fixed to the support portions 3 oppositely arranged on the two sets of telescopic linkage mechanisms 1. In this embodiment, the slat 4 and the upper end of the support portion 3 are snap-fitted together. Specifically, a first slot is provided at the upper end of the support portion 3, and a second slot 4c corresponding to the first slot is provided at the lower part of both ends of the slat 4. The slat 4 and the support portion 3 are snap-fitted together through the first slot and the second slot 4c. The snap-fit structure facilitates the replacement of the slat 4. In other embodiments, the slat 4 can also be directly welded to the support portion 3.
[0033] The slat 4 is also provided with through holes 4a. Specifically, each slat 4 is provided with two through holes 4a, and the two through holes 4a are located at both ends of the slat 4 respectively.
[0034] The slide bar 5 passes through all the through holes 4a of the slats 4, and the slide bar 5 can slide relative to the slats 4 on the through holes 4a.
[0035] Preferably, the edges of the two end faces of the through hole 4a are rounded, making the cross-section of the inner arc surface of the through hole 4a semi-circular, with a shape similar to the inner arc surface of a bracelet. This structure reduces the contact area between the through hole 4a and the slide bar 5. Thus, on the one hand, it facilitates the sliding of the slide bar 5 relative to the strip 4, and on the other hand, it reduces the possibility of the slide bar 5 getting stuck with the through hole 4a during extension and retraction.
[0036] In this embodiment, the scissor-type telescopic linkage mechanism, originally used for lifting, is rotated by 90° to adjust the spacing between adjacent slats 4.
[0037] Preferably, this embodiment also includes a base 6, with rollers 2a fitting against and sliding on the base 6. One end of the telescopic linkage mechanism 1 is fixed to the base 6, and the other end of the telescopic linkage mechanism 1 is connected to a linear drive device, which drives the telescopic linkage mechanism 1 to extend and retract.
[0038] Furthermore, the base 6 is made of welded square tubing. A set of rollers 2a below the telescopic linkage mechanism 1 is mounted on a square tubing, and during telescopic movement, the rollers 2a slide back and forth only along the length of the square tubing. In other embodiments, the base 6 can also be made by splicing square tubing together using corner pieces.
[0039] Preferably, the linear drive device includes a motor, a gear, and a rack. The motor drives the gear to rotate, and the gear drives the rack to perform linear reciprocating motion. The rack is connected to the other end of the telescopic linkage mechanism 1 below. In other embodiments, the linear drive device may be a cylinder.
