Description

Technical Field

[0001] This utility model relates to the technical field of laser cutting machines, specifically a multi-diameter support device for a laser tube cutting machine. Background Technology

[0002] Laser pipe cutting machines are high-end mechanical equipment for the precision cutting of raw pipe materials. They typically consist of a laser generator, gantry crane, machining center, round pipe clamping fixtures, and a CNC lathe control panel. Currently, many laser pipe cutting machines utilize continuous diameter changing technology to support the pipes. During the laser cutting process, the pipe diameter can be seamlessly adjusted according to actual needs. This means the machine can handle pipe diameter changes from small to large without requiring separate tooling or mold changes. Achieving continuous diameter changing technology requires a complex mechanical control system, resulting in relatively high equipment costs. Due to the involvement of precision control systems and automatic adjustment devices, maintenance requires more professional knowledge and technical support. Certain pipe materials may not be suitable for continuous diameter changing. For some small and medium-sized enterprises handling relatively fixed types of pipes and with high requirements for equipment costs and maintenance, multi-diameter support may be a more economical and practical choice. Utility Model Content

[0003] To address the aforementioned shortcomings, this utility model provides the following technical solution:

[0004] A multi-diameter support device for a laser tube cutting machine includes a bed, with guide rails on both sides of the bed. A sliding mounting block is mounted on each guide rail. A fixed seat is located at the center of each sliding mounting block, and a hydraulic telescopic column is located at the center of the fixed seat. A fixed block is located at the top of the hydraulic telescopic column. A semi-circular groove is longitudinally formed on the fixed block, and several mounting grooves are longitudinally formed inside the fixed block. A support block is located within each mounting groove. A groove with the same arc as the semi-circular groove is formed on the support block. An arc-shaped groove is formed at the bottom of the groove. Sliding grooves are formed on the inner sides of the support blocks at the groove positions on both sides of the arc-shaped groove, and sliding blocks are located within each sliding groove.

[0005] Furthermore, the groove is provided with a horizontally inwardly arranged hydraulic telescopic rod, and the top of the hydraulic telescopic rod is provided with the sliding block.

[0006] Furthermore, the space formed by the bottom of the support block and the mounting groove is an oil cavity, and an oil pipe is provided on the fixing block at the bottom of the oil cavity to connect to the hydraulic oil tank.

[0007] Furthermore, the mounting slots are separated by partitions, and the top of the partitions is tangent to the bottom arc surface of the semicircular slots.

[0008] Furthermore, the top support block of the chute is equipped with an oil pipe for supplying oil to the hydraulic telescopic rod.

[0009] Furthermore, the radius of the arc-shaped groove at the bottom of the support block increases sequentially from the inside to the outside.

[0010] Furthermore, the centerlines of the arc-shaped groove and the semi-circular groove are in the same vertical plane.

[0011] The beneficial effects of this utility model are: 1. By simplifying the structural design, this utility model effectively reduces equipment costs and maintenance requirements, and can support various diameters. It is an economical and practical choice for small and medium-sized enterprises that process pipe fixing. 2. This utility model has a simple structure and provides effective support through slider fixing and arc surface support. When necessary, this structure can also fix pipes of different diameters to achieve the same support effect as a variable diameter support device. Attached Figure Description

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Combination Figures 1 to 4 Shown:

[0019] A multi-diameter support device for a laser tube cutting machine includes a bed 1, with guide rails 2 on both sides of the bed 1. A sliding mounting block 3 is mounted on each guide rail 2. A fixed seat 4 is located at the center of the sliding mounting block 3. A hydraulic telescopic column 5 is located at the center of the fixed seat 4. A fixed block 6 is located at the top of the hydraulic telescopic column 5. A semi-circular groove 7 is longitudinally formed on the fixed block 6. Several mounting grooves 8 are longitudinally formed inside the fixed block 6. Partitions 15 separate the mounting grooves 8. The top of the partitions 15 is tangent to the bottom arc surface of the semi-circular groove 7 to prevent excessive height from affecting the support of the semi-circular groove 7.

[0020] Each mounting slot 8 is equipped with a support block 9. The support block 9 has a groove 10 with the same arc as the semi-circular groove 7. The bottom of the groove 10 has an arc groove 11. The space formed by the bottom of the support block 9 and the mounting slot 8 is an oil cavity 14. The bottom fixing block 6 of the oil cavity 14 is equipped with an oil pipe connected to the hydraulic oil tank. The hydraulic system provides the corresponding support power, which is more stable. The radius of the arc groove 11 at the bottom of the support block 9 increases from the inside to the outside to support different pipe diameters.

[0021] The inner side of the support block 9 at the groove 10 position on both sides of the arc groove 11 is provided with a sliding groove 12. A sliding block 13 is provided in each sliding groove 12. A hydraulic telescopic rod is provided horizontally inward in the sliding groove 12. A sliding block 13 is provided at the top of the hydraulic telescopic rod. An oil pipe is provided on the support block 9 at the top of the sliding groove 12 for supplying oil to the hydraulic telescopic rod. The extension and retraction control of the hydraulic telescopic rod is achieved by the sliding block moving in the sliding groove 12 to clamp the pipe.

[0022] The centerlines of the arc groove 11 and the semi-circular groove 7 are on the same vertical plane, which facilitates the alignment of the pipe and the clamping device.

[0023] Working principle: First, the pipe is placed in the semi-circular groove for support. Depending on the pipe diameter, a hydraulic device raises the corresponding support block, aligning the pipe with the arc-shaped groove of the support block. At this point, a hydraulic telescopic rod pushes a slider within the groove to further secure the pipe from the side. The lifting and lowering of the hydraulic telescopic column transports the pipe to the corresponding height of the clamp. If necessary, the arc-shaped or semi-circular groove provides bottom support. The side clamping of the slider can accommodate pipes of various diameters.
