Description

Technical Field

[0001] This utility model relates to the field of cladding laser head technology, and in particular to a cladding laser head with an ultra-wide spot size. Background Technology

[0002] In modern industrial production, laser cladding technology plays an increasingly crucial role as an important method for material surface modification and repair. Laser cladding can prepare high-performance alloy surfaces on inexpensive metal substrates without affecting the properties of the matrix, effectively reducing costs and saving precious and rare metal materials. Therefore, it is highly valued by industrialized countries. In laser cladding equipment, the laser cladding head is one of the core components, and its performance directly affects the effect and efficiency of laser cladding.

[0003] Currently, the connection between the laser head and the machine head in existing technologies requires multiple bolts for fixation. When disassembling, repairing, or replacing the machine head, each bolt must be loosened and stored one by one. Frequent bolt removal can easily cause problems such as stripped threads and wear on the connection end face. In addition, improper operation may cause deformation of the laser head shell, and the bolts are prone to rusting under long-term use, affecting the service life. Utility Model Content

[0004] To address the shortcomings of the present invention, which require loosening and storing bolts one by one during disassembly, maintenance and replacement, frequent bolt removal can easily cause thread stripping, wear on the connection end face, and may even lead to deformation of the laser head shell due to improper operation. Furthermore, the bolts are prone to rusting under long-term use, affecting the service life, the present invention provides an ultra-wide spot cladding laser head with the advantages of convenient and quick disassembly and assembly and adjustable angle, thus solving the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: an ultra-wide spot cladding laser head, including a machine head, a laser device at the front end of the machine head, a mounting frame at the middle of the machine head, a fixing plate fixedly mounted on the middle of the side of the laser device near the machine head, a groove in the middle of the fixing plate, two support plates fixedly mounted at the bottom of the mounting frame, a bidirectional screw rotatably mounted on the inner side of the two support plates, a forward and reverse motor mounted on the side of the support plates, the output end of the forward and reverse motor connected to one side of the bidirectional screw via a coupling, movable plates threaded on both sides of the bidirectional screw, rectangular plates fixedly mounted on both sides of the mounting frame, the rectangular plates having a hollow structure inside, and the upper ends of the two movable plates respectively located inside the rectangular plates, two limiting plates provided at both ends of the inner side of the mounting frame, the front end of the limiting plates having a beveled structure, and the limiting plates engaging with the groove when the fixing plate is located inside the mounting frame.

[0006] Preferably, two telescopic rods are fixedly installed on one side of the two movable plates near the limiting plate, and the other side of the telescopic rods is fixedly installed on the side of the limiting plate.

[0007] The telescopic rod provides movement guidance and support for the limiting plate, ensuring its smooth sliding under the action of the movable plate and guaranteeing the stability of engaging or disengaging from the groove.

[0008] Preferably, a return spring is sleeved on the outer side of each telescopic rod, and the two sides of the return spring are respectively connected to the corresponding surfaces of the movable plate and the limiting plate.

[0009] By setting a reset spring, the elastic force drives the limit plate to automatically engage with the groove of the fixing plate, realizing automatic locking after laser equipment installation and elastic reset during disassembly.

[0010] Preferably, the rectangular plate has guide rails at both the top and bottom ends, and two sliders are fixedly installed at the top end of the movable plate, with the sliders slidably installed on the inner side of the guide rails.

[0011] By setting up guide rails and sliders, precise guidance is provided for the movement of the movable plate, ensuring that it slides smoothly along a fixed trajectory and improving the synchronization and stability of the movement of the limit plate.

[0012] Preferably, a hidden groove is provided in the middle of the machine head, and a rotary motor is installed inside the hidden groove. The output end of the rotary motor is connected to the middle of the mounting frame through a coupling.

[0013] By using a rotary motor, the mounting bracket is driven to rotate the laser equipment, enabling flexible adjustment of the laser spot angle and improving processing adaptability and precision.

[0014] Preferably, an arc-shaped plate is fixedly installed at the bottom of the machine head, and a limiting groove is formed on the surface of the arc-shaped plate. A support rod is fixedly installed at the bottom of the laser device, and when the laser device is fixed inside the mounting frame, the other side of the support rod is slidably installed inside the limiting groove.

[0015] By setting up the arc plate and limiting slide, a trajectory constraint is formed on the bottom support rod of the laser equipment, ensuring smooth movement when rotating and adjusting the angle, and improving the accuracy and stability of angle adjustment.

[0016] This utility model has the following advantages:

[0017] 1. By setting two limiting plates inside the mounting frame, during installation, the fixing plate is inserted along the inner space of the mounting frame. After the front end of the fixing plate contacts the inclined surface of the limiting plate, the limiting plate is pushed outward and the return spring is compressed until the fixing plate is fully inserted. The elastic force of the return spring drives the limiting plate to quickly lock into the groove of the fixing plate, realizing the automatic locking and fixing of the laser equipment. During disassembly, the forward and reverse motor drives the bidirectional screw to rotate. The bidirectional screw drives the two movable plates on both sides to move outward along the guide rail. The movable plates pull the limiting plate outward, causing the limiting plate to disengage from the groove of the fixing plate. At this time, the laser equipment can be directly pulled out of the mounting frame, simplifying the installation and disassembly of the laser head and improving work efficiency.

[0018] 2. By setting a rotary motor and an arc-shaped plate limiting slide groove structure in the middle of the machine head, when the rotary motor drives the mounting frame to rotate the laser equipment around the central axis of the machine head, the support rod at the bottom of the laser equipment slides synchronously along the limiting slide groove of the arc-shaped plate. Since the limiting slide groove forms an arc-shaped constraint on the movement trajectory of the support rod, the laser equipment maintains a stable tilt angle adjustment during rotation. The irradiation direction of the laser spot can be precisely adjusted according to processing requirements. This not only realizes the flexibility of multi-angle processing of the laser head, but also improves the stability and positioning accuracy of the adjustment process through the sliding cooperation between the support rod and the limiting slide groove, avoiding the processing limitations caused by the fixed angle of the traditional bolt fixing structure.

[0024] 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.

[0025] Please see Figures 1-4 A cladding laser head with an ultra-wide spot size includes a head 1, a laser device 2 at the front end of the head 1, a mounting frame 7 in the middle of the head 1, a fixing plate 3 fixedly mounted on the middle of the side of the laser device near the head 1, a groove 4 in the middle of the fixing plate 3, two support plates 9 fixedly mounted at the bottom of the mounting frame 7, a bidirectional screw 11 rotatably mounted on the inner side of the two support plates 9, and a forward and reverse motor 10 mounted on the side of the support plates 9, which drives the bidirectional screw 11 to rotate inside the two support plates 9.

[0026] The output end of the reversible motor 10 is connected to one side of the bidirectional screw 11 via a coupling. Movable plates 12 are threaded onto both sides of the bidirectional screw 11. Rectangular plates 8 are fixedly mounted on both sides of the mounting bracket 7. The rectangular plates 8 have a hollow structure inside, and the upper ends of the two movable plates 12 are respectively located inside the rectangular plates 8. Two limiting plates 13 are provided at both ends of the inner side of the mounting bracket 7. When disassembling the laser device 2, the reversible motor 10 drives the bidirectional screw 11 to rotate. The bidirectional screw 11 drives the movable plates 12 on both sides to move outward along the guide rail 16. The movable plates 12 pull the limiting plates 13 outward, causing the limiting plates 13 to disengage from the grooves 4 of the fixed plate 3. At this time, the device can be directly disassembled. The laser equipment is pulled out from the mounting bracket 7, which simplifies the installation and disassembly of the laser head and improves work efficiency. The front end of the limiting plate 13 has a beveled structure. When the fixing plate 3 is located inside the mounting bracket 7, the limiting plate 13 is engaged in the groove 4. By setting two limiting plates 13 in the mounting bracket 7, the fixing plate 3 is inserted along the inner space of the mounting bracket 7 during installation. After the front end of the fixing plate 3 contacts the bevel of the limiting plate 13, the limiting plate 13 is pushed to move outward and compress the return spring 15 until the fixing plate 3 is fully inserted. The elastic force of the return spring 15 drives the limiting plate 13 to quickly engage in the groove 4 of the fixing plate 3, thereby realizing the automatic clamping and fixing of the laser equipment.

[0027] Please see Figures 2-4Two telescopic rods 14 are fixedly installed on one side of the two movable plates 12 near the limiting plate 13. The other side of the telescopic rods 14 is fixedly installed on the side of the limiting plate 13. A return spring 15 is sleeved on the outer side of each telescopic rod 14. The telescopic rods 14 can ensure that the limiting plate 13 moves smoothly and accurately engages into the groove 4 of the fixed plate 3. At the same time, the return spring 15 provides elastic pre-tightening force to make the connection stable. The two sides of the return spring 15 are connected to the corresponding surfaces of the movable plate 12 and the limiting plate 13 respectively. By utilizing its elastic deformation, the limiting plate 13 automatically engages into the groove 4 of the fixed plate 3 to achieve quick fixation and enhance stability.

[0028] The rectangular plate 8 has guide rails 16 at both the top and bottom. Two sliders 17 are fixedly installed on the upper end of the movable plate 12. The sliders 17 are slidably installed on the inner side of the guide rails 16. The sliding cooperation between the guide rails 16 and the sliders 17 provides rigid guiding constraints for the movement of the movable plate 12, ensuring that it slides smoothly along a fixed trajectory under the drive of the bidirectional screw 11. A hidden groove 5 is provided in the middle of the head 1. A rotary motor 6 is installed inside the hidden groove 5. The output end of the rotary motor 6 is connected to the middle of the mounting frame 7 through a coupling. The rotary motor 6 drives the mounting frame 7 to drive the laser equipment to rotate around the central axis of the head 1, so as to realize the continuous adjustment of the spot irradiation angle and meet the multi-angle cladding requirements of different workpiece surfaces or processing paths.

[0029] An arc-shaped plate 18 is fixedly installed at the bottom of the laser head 1. A limiting groove 19 is formed on the surface of the arc-shaped plate 18. A support rod 20 is fixedly installed at the bottom of the laser device 2. When the laser device is fixed inside the mounting frame 7, the other side of the support rod 20 is slidably installed inside the limiting groove 19. By setting a rotary motor 6 and an arc-shaped plate 18 limiting groove 19 structure in the middle of the laser head 1, when the rotary motor 6 drives the mounting frame 7 to rotate the laser device around the central axis of the laser head 1, the support rod 20 at the bottom of the laser device slides synchronously along the limiting groove 19 of the arc-shaped plate 18. Since the limiting groove 19 forms an arc-shaped constraint on the movement trajectory of the support rod 20, the laser device maintains a stable tilt angle adjustment during rotation. The beam irradiation direction can be precisely adjusted according to processing requirements. This not only realizes the flexibility of multi-angle processing of the laser head, but also improves the stability and positioning accuracy of the adjustment process through the sliding cooperation between the support rod 20 and the limiting groove 19, avoiding the processing limitations caused by the fixed angle of the traditional bolt fixing structure.

[0030] Working principle: In actual use, first align the fixing plate 3 of the laser equipment with the inner space of the mounting frame 7, and push the fixing plate 3 horizontally to insert it into the mounting frame 7. When the front end of the fixing plate 3 contacts the inclined surface of the limiting plate 13, the guiding effect of the inclined surface forces the limiting plate 13 to move outward. The return spring 15 is compressed by the telescopic rod 14. At this time, the limiting plate 13 gradually disengages from the initial locking state. As the fixing plate 3 continues to go deeper, when the groove 4 of the fixing plate 3 aligns with the limiting plate 13, the elastic potential energy of the return spring 15 is released, driving the limiting plate 13 to move quickly inward through the telescopic rod 14, so that the front end of the limiting plate 13 is locked into the groove 4, completing the automatic locking and fixing of the laser equipment.

[0031] When the laser equipment needs to be disassembled, the forward and reverse motor 10 is started. The output end of the motor drives the bidirectional screw 11 to rotate through the coupling. Since the threads on both sides of the bidirectional screw 11 rotate in opposite directions, the rotation will drive the movable plates 12 on both sides to move outward synchronously along the guide rail 16. The movable plates 12 cause the limiting plate 13 to gradually disengage from the groove 4 of the fixed plate 3. When the limiting plate 13 has completely exited the groove 4, the laser equipment can be directly pulled out horizontally from the mounting frame 7 to complete the disassembly process. The entire disassembly process is automatically driven by the motor, avoiding the tedious operation of loosening the bolts one by one in the traditional way.

[0032] During laser cladding, if it is necessary to adjust the irradiation angle of the laser spot, the rotary motor 6 in the hidden groove 5 can be started. The output end of the rotary motor 6 drives the mounting frame 7 to rotate around the central axis of the machine head 1. The mounting frame 7 synchronously drives the laser equipment to rotate. At this time, the support rod 20 at the bottom of the laser equipment slides in an arc along the limiting slide groove 19 of the arc plate 18. The trajectory constraint of the limiting slide groove 19 ensures that the laser equipment maintains a stable tilt angle change during rotation. By controlling the rotation angle of the rotary motor 6, the irradiation direction of the laser equipment can be precisely adjusted to adapt to the curved surface shape or processing path requirements of different workpieces, and realize multi-angle cladding operation.
