Detailed Description of the Embodiment
[0024] The present utility model provides a segmented chassis and a laser pipe cutting machine. To make the objectives, technical solutions, and effects of the present utility model clearer and more definite, the following further elaborates on the present utility model with reference to the accompanying drawings and by way of examples. It should be understood that the specific examples described herein are only used to explain the present utility model and are not used to limit the protection scope of the present utility model.
[0025] Please refer to Figures 1-3 , the present utility model provides a segmented chassis, including a first frame body 1 and a second frame body 2 spliced horizontally. A first vertical end plate 3 is provided at the splicing end of the first frame body 1, and a second vertical end plate 4 is provided at the splicing end of the second frame body 2. A plurality of first docking holes 31 are provided on the first vertical end plate 3, and second docking holes with the same number and one-to-one correspondence as the first docking holes 31 are provided on the second vertical end plate 4. Docking screws 33 pass through the first docking holes 31 and are connected to the second docking holes. Two position adjustment structures 5 for adjusting the splicing position of the first frame body 1 are provided on the second vertical end plate 4, and an avoidance opening 32 for avoiding the installation of the position adjustment structure 5 is provided on the first vertical end plate 3.
[0026] Compared with the prior art, the segmented chassis provided by the present utility model has the following advantages:
[0027] 1. The chassis is composed of a first frame body 1 and a second frame body 2, and is spliced through the docking holes on the first vertical end plate 3 and the second vertical end plate 4, so that the length of the chassis can be flexibly adjusted according to actual needs. This design not only meets the requirements of different processing lengths, but also facilitates increasing or decreasing the number of chassis segments when needed, thereby enhancing the scalability and adaptability of the equipment.
[0028] 2. The segmented design of the chassis solves the problem of size limitation encountered by traditional integral chassis during transportation. When long-distance transportation is required, especially for export, the chassis can be disassembled into smaller frame bodies and easily loaded into standard containers, reducing logistics costs and improving transportation efficiency. At the same time, on-site installation is also more convenient, reducing the complexity of handling and assembling large equipment.
[0029] 3. Through the docking holes and the position adjustment structure 5 provided on the first vertical end plate 3 and the second vertical end plate 4, accurate alignment of each section of the chassis during splicing is ensured, avoiding the instability of the overall structure caused by cumulative errors.
[0030] Specifically, the first frame body 1 further includes two first side seats 11 and a second side seat 12 arranged parallel to each other on the left and right, and a plurality of first connecting beam bodies 13 arranged between the first side seat 11 and the second side seat 12. Adding a plurality of first connecting beam bodies 13 between the first side seat 11 and the second side seat 12 not only increases the lateral support force of the chassis, but also improves the rigidity of the overall structure, effectively preventing deformation under heavy load conditions and ensuring the stability of long-term operation.
[0031] Further, as shown in Figure 3 and Figure 4 The positioning structure 5 includes a reference block 51, an up-and-down positioning screw 52, a left-and-right positioning screw 53, and a fixing screw 54. The reference block 51 is provided with a vertical threaded hole 511 for cooperating with the up-and-down positioning screw 52, a longitudinal threaded hole 512 for cooperating with the left-and-right positioning screw 53, and a countersunk hole 513 for cooperating with the fixing screw 54. A flat plate 34 is fixedly provided on the back surface of the first vertical end plate 3 and is located above the reference block 51. The up-and-down positioning screw 52 faces the bottom surface of the flat plate 34. The left-and-right positioning screws 53 on one of the positioning structures 5 face the first side seat 11, while the left-and-right positioning screws 53 on the other positioning structure 5 face the second side seat 12. The fixing screw 54 is threadedly connected to the second vertical end plate 4. Under the action of gravity of the first frame body 1, the flat plate 34 will press against the top end of the up-and-down positioning screw 52, and the two left-and-right positioning screws 53 will tightly press against the first side seat 11 and the second side seat 12 in the opposite direction.
[0032] By turning the up-and-down positioning screw 52 and the left-and-right positioning screw 53, the staff can simply and precisely fine-tune the splicing position between the first frame body 1 and the second frame body 2, ensuring the height and width consistency between each section of the chassis, and greatly improving the accuracy and stability of the laser tube cutting machine during cutting operations. This fine-tuning mechanism is particularly important for processing long tubes with high precision requirements.
[0033] In this embodiment, the first side seat 11 includes a first lower cross beam 111 and a first upper cross beam 112 stacked on the top surface of the first lower cross beam 111. The second side seat 12 includes a second lower cross beam 121 and a second upper cross beam 122 stacked on the top surface of the second lower cross beam 121. A plurality of groups of support leg assemblies 6 are provided at the bottoms of the first lower cross beam 111 and the second lower cross beam 121. Both the first upper cross beam 112 and the second upper cross beam 122 are rectangular tubes. Due to the high structural strength and non-deformable characteristics of the rectangular tubes, the chassis can better carry heavy long pipes in practical applications. The bottom surface of the first upper cross beam 112 and the top surface of the first lower cross beam 111 are fixedly connected by welding, and the bottom surface of the second upper cross beam 122 and the top surface of the second lower cross beam 121 are fixedly connected by welding.
[0034] The first connecting beam body 13 includes a first connecting pipe 131 connecting the first upper cross beam 112 and the second upper cross beam 122, and a second connecting pipe 132 connecting the first lower cross beam 111 and the second lower cross beam 121. The first connecting pipe 131 is stacked above the second connecting pipe 132. The first connecting pipe 131 and the second connecting pipe 132 also adopt rectangular pipes, which have good connection strength. The two ends of the first connecting pipe 131 are respectively connected to the first upper cross beam 112 and the second upper cross beam 122 by welding, and the two ends of the second connecting pipe 132 are respectively connected to the first lower cross beam 111 and the second lower cross beam 121 by welding.
[0035] To facilitate the collection of tail materials, the first side seat 11 and the second side seat 12 form a tail material dropping port 14, and the first lower cross beam 111 forms a break 15 at the tail material dropping port 14. The receiving basin can enter the interior of the chassis through the break 15 and is located directly below the tail material dropping port 14. After the moving chuck 83 drops the tail material into the tail material dropping port 14, it falls into the receiving basin, which is convenient for subsequent processing.
[0036] In this embodiment, the second frame body 2 further includes two third side seats 21 and fourth side seats 22 arranged parallel to each other left and right, and a plurality of second connecting beam bodies 23 arranged between the third side seats 21 and the fourth side seats 22. The third side seat 21 includes a third lower cross beam 211 and a third upper cross beam 212 stacked on the top surface of the third lower cross beam 211. The fourth side seat 22 includes a fourth lower cross beam 212 and a fourth upper cross beam 213 stacked on the top surface of the fourth lower cross beam 212. A number of groups of support leg assemblies 6 are provided at the bottoms of the third lower cross beam 211 and the fourth lower cross beam 212. The double-layer cross beam design (the third upper cross beam 212 and the third lower cross beam 211, the fourth upper cross beam 213 and the fourth lower cross beam 212) increases the vertical load-bearing capacity of the chassis, can more stably support the cutting operation of heavy large pipes. At the same time, the stacked placement method improves the structural compactness, reduces the use of materials, and realizes the balance between structural strength and economy.
[0037] For the specific material selection and design of the third side seat 21, the fourth side seat 22 and the second connecting beam body 23 in the second frame body 2, reference can be made to the first frame body 1, which will not be elaborated here.
[0038] A chuck mounting seat 9 is provided at the end of the third upper cross beam 212 and the fourth upper cross beam 213 away from the second vertical end plate 4. The chuck mounting seat 9 is jointly supported by the third lower cross beam 211 and the fourth lower cross beam 212. The fixed chuck 84 is installed on the chuck mounting seat 9, realizing the integrated design of the chuck mounting seat 9 and the chassis, simplifying the installation process, reducing the need for additional brackets, and improving the overall structural compactness and operation efficiency. At the same time, the chuck mounting seat jointly supported by the third lower cross beam 211 and the fourth lower cross beam 212 ensures the stability and reliability of the fixed chuck 84 when bearing heavy loads.
[0039] The support leg assembly 6 includes a support plate 61 and a foot cup 62 provided at the bottom of the support plate 61. The support plate 61 is provided with a threaded hole that is threadedly connected to the screw on the foot cup 62. By rotating the adjusting screw, the levelness of the chassis can be adjusted. The setting of the foot cup 62 increases its contact area with the ground, thereby enhancing the friction force.
[0040] Preferably, multiple groups of lifting rings 7 are provided on both the first frame body 1 and the second frame body 2, which facilitates subsequent hoisting of the first frame body 1 and the second frame body 2 by a crane respectively, greatly improving the flexibility of assembly and movement, reducing the risk of manual handling, and ensuring the safety of personnel and equipment during the handling process.
[0041] Sealing plates 16 are provided at the non-connected ends of the first frame body 1 and the second frame body 2.
[0042] The present utility model further provides a laser pipe cutting machine, which includes the above-mentioned segmented chassis, a plurality of follower support mechanisms 81 provided on the segmented chassis, a moving chuck 83 provided on the first frame body 1, a fixed chuck 84 provided on the second frame body 2, an L-shaped support arm 86 provided outside the fixed chuck 84, a base 85 for supporting the L-shaped support arm 86, and a laser cutting assembly 82 provided on the L-shaped support arm 86 and behind the fixed chuck 84. Transversely extending guide rails and racks are provided on the first frame body 1 and the second frame body 2, such that a motor and a gear drivingly connected to the rack are configured on the moving chuck 83. When the motor operates, the moving chuck 83 can move horizontally on the first frame body 1 and the second frame body 2.
[0043] Benefiting from the design of the segmented chassis, not only the problems in transportation and installation of traditional laser pipe cutting machines are solved, but also the length of the chassis can be flexibly adjusted according to processing requirements, enhancing the adaptability of the equipment to different specifications of pipes. Especially when dealing with long pipes, a wider processing range is provided.
