Description

Technical Field

[0001] This invention relates to the field of laser drilling technology, specifically to an automated laser drilling machine for fasteners. Background Technology

[0002] Metal cutting equipment manufacturing, as a core sub-sector of high-end equipment manufacturing, is a key technological support for industries such as fastener precision machining, engineering machinery components, and high-end equipment production. Its technological iteration and product upgrades directly determine the processing accuracy, mass production stability, and production efficiency of metal precision forming. Laser drilling technology, with its core advantages such as non-contact processing, no tool wear, and adaptability to complex hole shapes and high-strength, difficult-to-machine materials, has become the mainstream technology direction for precision small hole machining in the metal cutting equipment manufacturing field. Corresponding automated laser drilling machines, by integrating functional modules such as automatic feeding, visual positioning, and CNC laser processing, can achieve continuous and batch drilling operations for fastener workpieces. In particular, for special fasteners such as lead-sealed screws with anti-tampering locking holes, automated laser drilling machines can use the thermal effect of a high-energy-density laser beam to rapidly melt, vaporize, and remove the metal material at the head of the lead-sealed screw. Combined with a CNC system that precisely controls the processing path and processing time, lead-sealed holes that meet the requirements for anti-tampering and anti-loosening locking are formed. This is currently the core processing equipment in the industrial mass production of lead-sealed screws.

[0003] Most of the automated laser drilling machines currently manufactured in the metal cutting equipment industry focus only on the drilling and forming process of lead seal holes. They generally lack supporting processing mechanisms and full-process processing capabilities for lead seal screws after laser drilling. They cannot simultaneously correct the inherent defects generated by laser drilling, which seriously affects the forming effect of laser drilling and the subsequent use effect of lead seal screws. Specifically, problems such as edge chipping, annular recasting layer on the hole wall, burrs on the inner wall, and taper deviation of the hole diameter caused by laser drilling will directly lead to the failure of the forming accuracy and hole wall smoothness of the lead seal hole to meet the design requirements due to the lack of subsequent inner wall grinding and hole correction processes. This will significantly reduce the yield and consistency of laser drilling. Furthermore, the untreated sharp holes and rough holes will directly cut or jam the locking line during the subsequent use of the lead seal screw, causing the core functions of anti-disassembly and anti-tampering of the lead seal screw to completely fail. At the same time, the lack of corresponding calibration and correction processes for problems such as local thermal deformation and hole position deviation caused by laser drilling will result in uneven distribution of preload and leakage of the sealing surface during the assembly of the lead seal screw. This will fail to meet the mandatory compliance requirements for use in scenarios such as measuring instruments and special equipment, and will seriously restrict the mass production efficiency and long-term reliability of the lead seal screw. Summary of the Invention

[0020] Example 1: Please refer to Figures 1-10 An automated laser drilling machine for fasteners includes a metal cutting equipment manufacturing table 1, a support frame 2 fixed to the top of the metal cutting equipment manufacturing table 1, and a laser drilling mechanism 6 disposed on one side of the support frame 2. The top of the laser drilling mechanism 6 is electrically connected to a control line 7. A placement seat 3 is fixed to one side of the bottom of the support frame 2. A placement groove 34 is opened inside the placement seat 3. A positioning mechanism 4 is fixedly installed on the side of the support frame 2 near the placement seat 3.

A cutting and pressing component is disposed at one end of the electric telescopic rod 24.

[0021] The laser drilling mechanism 6 is externally fixedly mounted with a mounting bracket 5. The output end of the cylinder 8 is externally fixedly connected to the mounting bracket 5. Two guide rods 9 are symmetrically fixed at one end of the mounting bracket 5 near the cylinder 8. One end of each guide rod 9 is slidably inserted through the outside of the support frame 2.

[0022] An mounting base 10 is fixedly fitted on the outside of the auxiliary sleeve 11. One end of the mounting base 10 is fixedly installed on one side of the mounting bracket 5. A plastic sheath tube 12 is inserted inside the auxiliary sleeve 11.

[0023] A number of auxiliary balls 22 are embedded and rotatably mounted on the inner wall of the auxiliary sleeve 11. The drive insertion assembly includes a number of conveying wheels 19. The conveying wheels 19 are arranged around the lower end of the auxiliary sleeve 11. A number of friction blocks 21 are fixed on the outer periphery of each conveying wheel 19. Each conveying wheel 19 is in contact with the outer wall of the plastic sheath tube 12.

[0024] A positioning frame 15 is fixed to the lower end of each conveyor wheel 19 of the auxiliary sleeve 11. A rotating shaft 18 is fixedly inserted through the middle of the conveyor wheel 19. Both ends of the rotating shaft 18 are rotatably inserted through the lower end of the positioning frame 15. A drive motor 16 is fixedly installed on one side of the positioning frame 15.

[0025] A drive gear 17 is fixedly installed at the output end of the drive motor 16, and a limit gear 20 is fixedly installed at one end of the rotating shaft 18. The drive gear 17 and the limit gear 20 are meshed and connected. An auxiliary frame 13 is fixedly installed at the upper end of the mounting base 10. Several limit auxiliary rings 14 are sleeved on the outer periphery of the plastic sheath tube 12, and the several limit auxiliary rings 14 are all fixedly installed on the auxiliary frame 13.

[0026] A fixed frame 33 is fixedly mounted on the electric telescopic pole 24. A connecting frame 23 is fixedly installed on the top of the fixed frame 33. The end of the connecting frame 23 away from the fixed frame 33 is fixedly installed on the mounting base 10.

[0027] The cutting and pressing assembly includes a mounting block 25 and two arc-shaped cutters 26. The mounting block 25 is fixedly installed at the output end of the electric telescopic rod 24. The two arc-shaped cutters 26 are symmetrically arranged on both sides of the mounting block 25. Two limiting rods 27 are symmetrically fixed to the outside of each arc-shaped cutter 26 on the mounting block 25.

[0028] One end of each arc-shaped cutter 26 is slidably sleeved on two limiting rods 27 on the corresponding side. Each of the two limiting rods 27 is fitted with a compression spring 28, and the two ends of the compression spring 28 are fixedly connected to the arc-shaped cutter 26 and the mounting block 25, respectively.

[0029] A limiting frame 30 is fixedly installed on one side of the fixing frame 33 near each arc-shaped cutter 26. A second arc-shaped abutment block 32 is fixedly installed on the inner side of the end of the limiting frame 30 away from the fixing frame 33. A first arc-shaped abutment block 31 that cooperates with the second arc-shaped abutment block 32 is fixedly provided on each arc-shaped cutter 26. A heating block 29 is fixedly installed on the inner side of each arc-shaped cutter 26.

[0030] In this embodiment, when using this laser drilling device, the lead-sealed screw fastener to be processed is first placed into the placement slot 34 of the placement seat 3. The existing positioning mechanism 4 completes the precise clamping and positioning of the workpiece, so that the processing area of ​​the lead-sealed screw head is coaxially aligned with the laser beam focus of the laser drilling mechanism 6. This avoids the problems of hole position deviation and coaxiality deviation in laser drilling from the source, and ensures the basic forming accuracy of laser drilling.

[0031] After positioning is completed, the equipment is started. The control line 7 sends processing instructions to the existing laser drilling mechanism 6. The high-energy-density laser beam is focused by the optical module and precisely acts on the area to be processed on the head of the lead seal screw. The thermal effect of the laser beam is used to quickly melt, vaporize and remove the metal material in the target area. The CNC system completes the processing path control and forms a lead seal hole that meets the design requirements on the head of the bolt, thus completing the core laser drilling process.

[0032] After the laser drilling process is completed, cylinder 8 is activated and retracted, pulling the mounting frame 5 to move laterally along the two guide rods 9. The guide rods 9 ensure the straightness and repeatability of the translation process throughout, until the axis of the auxiliary sleeve 11 on the mounting frame 5 is completely coaxial with the axis of the lead seal hole that has just been processed. This achieves a seamless connection between laser drilling and the subsequent sheath insertion process, eliminating the need for secondary workpiece clamping and completely avoiding the hole position deviation problem caused by multiple clamping, while also significantly improving processing efficiency.

[0033] After the workstation is aligned, the drive insertion assembly is started. The drive motor 16 drives the drive gear 17 at the output end to rotate. Through the meshing limit gear 20, the rotating shaft 18 and the conveyor wheel 19 rotate synchronously. The friction block 21 on the outer periphery of the conveyor wheel 19 can increase the contact friction between the plastic sheath tube 12 and the plastic sheath tube 12, and stably drive the plastic sheath tube 12, made of wear-resistant engineering plastic, to feed downward along the auxiliary sleeve 11. The auxiliary ball bearings 22 embedded in the inner wall of the auxiliary sleeve 11 can greatly reduce the sliding resistance of the plastic sheath tube 12 feed, ensuring that the feed process is smooth and without jamming. At the same time, the multiple sets of limit auxiliary rings 14 on the auxiliary frame 13 at the upper end of the mounting base 10 radially limit the plastic sheath tube 12 throughout the entire process, avoiding radial wobble during the feed process, until the plastic sheath tube 12 completely penetrates the lead seal hole, and a fixed length of processing material shank is reserved at both ends. The core technical effect of this process is that, for lead-sealed holes with recast layers, burrs, and taper deviations on the inner wall after laser drilling, the implanted plastic sheath tube 12 can completely cover the inner wall of the lead-sealed hole, isolating the subsequent lead-sealing wire from direct contact with the metal hole wall. This fundamentally solves the problems of sealing wire jamming, wear, and breakage caused by inherent defects in laser drilling, greatly improving the core performance and functional reliability of the laser-drilled finished product, and fully serving the optimization of the laser drilling process.

[0034] After the plastic sheath tube 12 is fed into position, the electric telescopic rod 24 is activated, driving the entire cutting and pressing assembly to feed towards the lead-sealing screw until the cutting edge of the arc-shaped cutter 26 is flush with the end faces of the lead-sealing hole. During the feeding process, the cutting edges of the two symmetrically arranged arc-shaped cutters 26 first contact the pre-reserved material shanks at both ends of the plastic sheath tube 12, simultaneously completing the fixed-length cutting of the excess material shanks at both ends, so that the main body length of the plastic sheath tube 12 is perfectly matched with the length of the lead-sealing hole, and the cut end face is flush with the outer wall of the bolt head. The technical effect of this process is that by simultaneously completing the fixed-length cutting of both ends of the sheath tube through the symmetrical arc-shaped cutters 26, the length accuracy of the plastic sheath tube 12 is guaranteed, and the sheath tube is prevented from protruding from the outer wall of the bolt head, affecting the subsequent wrench assembly and sealing surface fit. At the same time, the cutting process and the sheath tube insertion process are integrated into the same station, eliminating the need for additional independent cutting equipment, greatly improving the processing efficiency of the entire laser drilling process, and perfectly adapting to the mass industrial production needs of lead-sealing screws.

[0035] After the fixed-length cutting is completed, the electric telescopic rod 24 drives the cutting and pressing assembly to continue to feed slightly. At this time, the second arc-shaped contact block 32 at the end of the upper limit frame 30 of the fixed frame 33 is in stable contact with the first arc-shaped contact block 31 on the arc-shaped cutter 26. As the feed continues to increase, the second arc-shaped contact block 32 applies a stable radial thrust to the first arc-shaped contact block 31, pushing the two arc-shaped cutters 26 to slide towards each other along the limit rod 27 on the corresponding side. The compression spring 28 is compressed synchronously until the inner pressing surface of the arc-shaped cutter 26 is completely in contact with the cut end face of the plastic sheath tube 12. At this time, the heating block 29 pre-installed inside the arc-shaped cutter 26 has been preheated to a set temperature that matches the material of the sheath tube. The heat is evenly conducted to the end face of the plastic sheath tube 12 through the cutter body, so that the plastic on the end face melts evenly. The molten plastic can fill the chipped edges and burrs of the hole formed by laser drilling, and simultaneously complete the non-contact repair of the defects of the laser drilling hole, without the need for additional grinding and chamfering processes, which greatly improves the forming accuracy and surface quality of laser drilling. On the other hand, it can form annular limiting protrusions that fit the hole wall at both ends of the lead-sealed hole. After cooling and shaping, it forms a dual fixing effect of mechanical interlocking and thermal fusion bonding with the lead-sealed hole, which prevents the plastic sheath tube 12 from shifting or falling off during the insertion, tightening and long-term use of the lead-sealed wire, and ensures the long-term protective effect of the sheath tube. It solves the industry pain point of the failure of the core functions of anti-disassembly and anti-tampering of the lead-sealed screw after laser drilling from the root. Meanwhile, the heat-affected area of ​​the entire hot-melt fixing process is limited to the end face of the sheath tube, with no excess heat conducted to the assembly and contact surface of the bolt head. This completely avoids the problems of warping of the assembly surface and sealing failure caused by thermal deformation, ensuring that the finished products fully meet the mandatory compliance requirements of scenarios such as measuring instruments and special equipment, and greatly improving the yield and long-term reliability of laser drilling products.

[0036] After the entire processing is completed, the electric telescopic rod 24 drives the cutting and pressing assembly to retract as a whole, the first arc-shaped contact block 31 and the second arc-shaped contact block 32 disengage, the compression spring 28 rebounds and resets, and drives the two arc-shaped cutters 26 to slide back to the initial position along the limit rod 27; at the same time, the cylinder 8 extends, pushes the mounting bracket 5 to move and reset along the guide rod 9, drives the laser drilling mechanism 6 back to the initial processing position, and the positioning mechanism 4 releases the clamp on the lead seal screw, so that the finished product with the entire processing can be taken out, realizing the fully automated and closed-loop processing of laser drilling of lead seal screws.
