Detailed Implementation

[0034] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5 This application will be described in further detail below.

[0035] Profile laser cutting positioning mechanism, refer to Figure 1 , Figure 2 , Figure 3 The system includes a workbench 11, with two parallel fixed grooves 12 on the upper end of the workbench 11. A slide rod 13 is installed in the fixed groove 12. The slide rod 13 is slidably connected to two slide blocks 14 located at both ends of the slide rod 13. A drive block 15 is installed on the upper end of the workbench 11 and connected to the corresponding slide block 14. A fixed block 2 is fixedly connected to the upper end of the drive block 15. The drive block 15 and the fixed block 2 are welded together. A screw 21 is installed through the fixed block 2. A fastening block 22 is rotatably connected to the end of the screw 21 facing the profile 4. A bearing is installed inside the fastening block 22 to realize the rotatable connection between the fixed block 2 and the drive block 15.

[0036] Reference Figure 1 The fastening block 22 has elastic protective layers 221 at both ends. The elastic protective layer 221 is made of rubber. The surface of the elastic protective layer 221 that contacts the profile 4 protrudes from the surface of the fastening block 22 that contacts the profile 4, so that the surface of the profile 4 will not be affected by the fastening block 22, thereby preventing the pressure or friction generated during the fastening process from damaging the surface of the profile 4.

[0037] Reference Figure 1 , Figure 2 Both ends of the fixed groove 12 have elastic elements 16 on their inner sidewalls that can abut against the sliding block 14. The elastic elements 16 are springs. The inner sidewalls of the fixed groove 12 are fixedly connected to the elastic elements 16, which can absorb and disperse the external impact force or vibration brought by the sliding block 14, thereby protecting the worktable 1 and its surrounding components from damage. The end of the elastic element 16 near the sliding block 14 has a rubber layer 17 that can abut against the sliding block 14, which improves the impact resistance of the worktable 1, plays a buffering role, and reduces the damage to the worktable 1 caused by the sliding block 14.

[0038] Reference Figure 4The drive block 15 has fixing components 3 at both ends for fixing the drive block 15 to the worktable 1. The fixing components 3 include two connecting plates 31 located at both ends of the drive block 15 and fastening bolts 32 threaded to the connecting plates 31 and abutting against the upper surface of the worktable 1. The connecting plates 31 are welded to the drive block 15. A driving member 34 is provided on the outer wall of the nut of the fastening bolt 32, so that the nut of the fastening bolt 32 can be tightened without the use of tools, which improves work efficiency. The fastening bolt 32 is fitted with an anti-loosening elastic member 33, which is an anti-loosening spring. One end of the anti-loosening elastic member 33 abuts against the nut of the fastening bolt 32, and the other end abuts against the connecting plate 31 to prevent the fastening bolt 32 from loosening.

[0039] Reference Figure 1 , Figure 5 A handle 23 is provided at the end of the screw 21 away from the fastening block 22, allowing the operator to easily turn the screw 21 without using other tools or applying excessive force. An anti-slip sleeve 231 is provided on the outer wall of the handle 23 to increase the friction between the handle 23 and the operator's hand and prevent slippage when turning the handle 23.

[0040] The implementation principle of this application embodiment is as follows: The worker places the profile 4 between two driving blocks 15, and the sliding block 14 slides in the fixed groove 12. The sliding block 14 drives the driving block 15 to slide in the opposite direction of the driving block 15. When the driving block 15 slides to the appropriate position in the fixed groove 12, the screw 21 is rotated using the handle 23 to accurately position the profile 4 until the profile 4 abuts against the protective layer 221 of the fastening block 22. The nut of the fastening bolt 32 is tightened so that the fastening bolt 32 abuts against the workbench 1 to fix the connecting plate 31. For profiles 4 of different sizes, adjusting the sliding block 14 to the appropriate position and using the screw 21 can position the profile 4, which is efficient, convenient and quick.
