Description

Technical Field

[0001] This utility model belongs to the field of laser cutting machine technology, and in particular relates to a protective structure at the end of a laser cutting machine bed. Background Technology

[0002] In the field of laser cutting machines, the structure of sliding rack bed is becoming increasingly common. Traditional laser cutting machines lack a limit for the sliding rack bed at the end of the bed. When subjected to excessive external force, the sliding rack bed may slide towards the end of the bed and detach, affecting work efficiency and posing safety hazards.

[0003] Existing laser cutting machine tool bed protective structures mostly use welded or screw-fixed metal plates, which are inconvenient to install and have poor adaptability. Once the working conditions change, it is difficult to adjust the position of the stop, affecting the protective effect. At the same time, the single material of the stop has limited fatigue resistance and is easily damaged. Utility Model Content

[0004] The purpose of this utility model is to provide a protective structure for the end of the bed of a laser cutting machine to solve the problems of inconvenient installation, poor adaptability, and poor fatigue resistance of common laser cutting machine bed protective structures.

[0005] This utility model achieves the above-mentioned objective through the following technical solution: it includes a cutting machine bed, which is composed of a bed frame and several sliding rack frames. The bed frame is provided with protective mechanisms at both ends. The protective mechanisms include L-shaped mounting parts and blocking components. The L-shaped mounting parts are provided with limiting blocks at both ends and are slidably connected.

[0006] Furthermore, the blocking component includes multiple layers of blocks, which, from the outside to the inside, consist of a first tungsten carbide alloy plate, an aluminum alloy block, a second tungsten carbide alloy plate, and a rolled steel block, and are connected by screws. The outermost first tungsten carbide alloy plate is twice as thick as the inner second tungsten carbide alloy plate, and the thicker first tungsten carbide alloy plate can withstand the impact of the heavy rack frame.

[0007] Furthermore, the blocking assembly also includes a C-shaped cable tray with a countersunk hexagonal screw running through it. One end of the countersunk hexagonal screw abuts against the multi-layer stop block. A sliding rod is provided above and below the countersunk hexagonal screw. The sliding rod passes through the C-shaped cable tray and is slidably connected. The sliding rod also includes a limiting head located on the outside of the C-shaped cable tray. The other end of the sliding rod is connected to the rolled steel block through threaded engagement.

[0008] Furthermore, the C-shaped cable tray and the L-shaped mounting component are connected by welding, and the L-shaped mounting component is provided with a square hole with the same volume as the multi-layer stop block.

[0009] Furthermore, the limiting block is a metal block with a T-shaped cross-section, and the limiting block is connected to the bed frame by screws. The L-shaped mounting part has a square sliding groove at the corresponding position of the limiting block.

[0010] Furthermore, the stroke of the multi-layer stop is equal to the length between the inner surface of the C-shaped cable tray and the outer surface of the L-shaped mounting component.

[0011] Beneficial effects: This utility model is reasonably designed and has the following beneficial effects: 1. In this utility model, the end protection structure of the laser cutting machine bed achieves the beneficial effects of dynamic impact resistance and buffering through the multi-layer heterogeneous material composite block design; the outer thickened tungsten carbide alloy plate provides a high-strength wear-resistant interface, the middle aluminum alloy layer effectively absorbs the inertial kinetic energy of the rack frame through plastic deformation, and the inner rolled steel and tungsten carbide layer form a rigid support system, so that the impact load is gradually attenuated along the gradient material, which significantly improves the fatigue resistance of the protective structure and avoids the problem of easy brittleness or excessive deformation of traditional single-material blocks; 2. In this utility model, the adjustable rigid propulsion system innovatively combines a C-shaped bridge and a sliding rod guide structure. The precise adjustment of the multi-layer stop stroke is achieved through the internal hexagon countersunk screw. The double mechanical limit of the sliding rod limit head and the inner wall of the bridge constitutes a guide mechanism, which can not only accurately control the stop position to adapt to different rack working conditions, but also prevent structural instability and displacement under overload. Compared with the traditional welded fixed protective device, it has better working condition adaptability. 3. In this utility model, the modular installation structure, through the cooperation design of T-shaped limiting blocks and square sliding grooves, enables the protective mechanism to be quickly disassembled and assembled while maintaining positioning accuracy. The three-dimensional limiting constraint of the L-shaped mounting parts and the end of the bed effectively suppresses vibration displacement. The volume matching design of the square hole and the stop block ensures that the impact force is transmitted evenly. The integrated design greatly reduces the risk of unplanned downtime caused by the failure of the protective structure. Attached Figure Description

Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Combination Figures 1 to 3 The laser cutting machine bed end protection structure shown includes a cutting machine bed, which is composed of a bed frame 1 and several sliding rack frames 2. Both ends of the bed frame 1 are provided with protective mechanisms 3. The protective mechanism 3 includes an L-shaped mounting part 31 and a blocking component 32. The L-shaped mounting part 31 is provided with limit blocks 33 at both ends and is slidably connected.

[0016] The blocking component 32 includes multiple blocks 321, which consist of a first tungsten carbide alloy plate, an aluminum alloy block, a second tungsten carbide alloy plate, and a rolled steel block from the outside to the inside, and are connected by screws. The thickness of the outermost first tungsten carbide alloy plate is twice the thickness of the inner second tungsten carbide alloy plate.

[0017] The blocking assembly 32 also includes a C-shaped cable tray 322, on which a countersunk hexagon screw 323 is provided. One end of the countersunk hexagon screw 323 abuts against the multi-layer stop block 321. A sliding rod 324 is provided above and below the countersunk hexagon screw 323. The sliding rod 324 passes through the C-shaped cable tray 322 and is slidably connected. The sliding rod 324 also includes a limiting head 325 located on the outside of the C-shaped cable tray 322. The other end of the sliding rod 324 is connected to the rolled steel block by thread engagement.

[0018] The C-shaped cable tray 322 and the L-shaped mounting component 31 are connected by welding. The L-shaped mounting component 31 has a square hole with the same volume as the multi-layer stop block 321.

[0019] The limiting block 33 is a metal block with a T-shaped cross section. The limiting block 33 is connected to the bed frame 1 by screws. The L-shaped mounting part 31 has a square groove 311 at the position opposite to the limiting block 33.

[0020] The stroke of the multi-layer stop 321 is equal to the length between the inner surface of the C-type cable tray 322 and the outer surface of the L-type mounting member 31.

[0021] Working Principle: During use, the laser cutting machine bed end protection structure 3 achieves dynamic limiting protection for the sliding rack frame 2 through the adjustable multi-layer stop assembly 32. Its workflow can be divided into three stages: Installation stage: The L-shaped mounting piece 31 is engaged with the square sliding groove 311 at the end of the bed frame 1 via the T-shaped limiting block 33, achieving rapid positioning and installation of the protection mechanism 3; Adjustment stage: By rotating the internal hexagon countersunk screw 323 on the C-shaped bridge 322, the multi-layer stop assembly composed of four layers of dissimilar materials is driven... Block 321 moves axially along slide bar 324 to form a rigid propulsion system, so that the outer thickened tungsten carbide alloy plate accurately abuts against the side of rack frame 2; during operation, when rack frame 2 generates sliding inertia during cutting operation, multi-layer stop block 321 disperses the impact load through gradient material structure (outer tungsten carbide layer resists wear, middle aluminum alloy layer absorbs energy and buffers, inner rolled steel provides support rigidity), slide bar 324, limit head 325 and C-shaped bridge 322 form double mechanical limit, ensuring that stop block 321 maintains stable movement within the set stroke.
