Description

Technical Field

[0001] This utility model relates to the field of laser cladding technology, and in particular to a micro-adjustment and positioning device for a laser cladding head. Background Technology

[0002] Laser cladding is an advanced surface engineering technology that uses a high-energy-density laser beam to rapidly fuse alloy powders or wires with the surface of a substrate material, forming a metallurgical bonding layer with specific properties on the substrate surface. This process can not only significantly improve the physicochemical properties of the part surface (such as wear resistance, corrosion resistance, and oxidation resistance), but can also be used to repair damaged parts or endow them with new functional properties.

[0003] During the laser cladding process, although the laser cladding head needs to be close to the workpiece surface to ensure accurate material deposition, the existing system has difficulty maintaining its accurate positioning when the cladding head moves. More importantly, after the cladding head reaches the predetermined position, due to the lack of stable positioning and fixing measures, slight vibration or displacement may occur during long-term operation, which will affect the quality and consistency of the cladding layer.

[0004] To address the existing problems, there is a need to provide a laser cladding head micro-adjustment and positioning device capable of positioning the laser cladding head. Summary of the Invention

[0005] To overcome the shortcomings of lacking positioning and fixing measures, this utility model provides a micro-adjustment and positioning device for laser cladding head.

[0006] The technical implementation scheme of this utility model is as follows: a micro-adjustment and positioning device for a laser cladding head, comprising a frame, a first clamp, a second clamp, an electric slide rail, an electric lifting frame, a laser connecting frame, a laser cladding frame, and a laser cladding head. The first clamp and the second clamp are installed inside the frame. An electric slide rail is installed on the rear side of the frame, and an electric lifting frame is slidably connected to the electric slide rail. The laser connecting frame is installed inside the electric lifting frame, and the laser cladding frame is connected to the front side of the laser connecting frame. The laser cladding head is installed at the bottom of the laser cladding frame. The device also includes a connecting ring, a first connecting plate, a second connecting plate, a pressing rod, and a... The system comprises a spring, a first connecting frame, a rotating shaft, a fixed frame, fixed balls, and wedge blocks. A connecting ring is installed on the laser cladding frame. A first connecting plate is connected to the rear side of the laser cladding frame, and a second connecting plate is connected to the rear side of the laser cladding frame. An extrusion rod is installed at the bottom of the first connecting plate, and the extrusion rod is slidably connected to the second connecting plate. A first spring is connected between the bottom of the first connecting plate and the top of the second connecting plate. A first connecting frame is connected to the front side of the electric lifting frame. A rotating shaft is symmetrically connected to the first connecting frame, and a fixed frame is connected to the rotating shaft. Several fixed balls are evenly spaced on the front side of the fixed frame, and wedge blocks are connected to the inner side of the fixed frame.

[0007] Furthermore, it also includes a second connecting frame, positioning rods and a limiting frame. The second connecting frame is connected to the left side of the laser cladding frame. Positioning rods are symmetrically connected to the second connecting frame. Limiting frames are symmetrically connected to the frame. The limiting frames are provided with a first sliding groove.

[0008] Furthermore, it also includes a sliding ring and a second spring. The rotating shaft has symmetrically opened second sliding grooves, on which the sliding ring is slidably connected. The bottom of the second connecting frame is connected to the top of the sliding ring, and the second spring is connected between the bottom of the second connecting frame and the top of the sliding ring.

[0009] Furthermore, the angle between the two mounting brackets is thirty degrees when in use.

[0010] Furthermore, the diameter of the positioning rod is equal to the width of the first groove.

[0011] Furthermore, the extrusion bar is located directly above the wedge block.

[0012] Compared with the prior art, the present invention has the following advantages: 1. During the descent of the laser cladding frame, the extrusion rod applies pressure to the wedge block, pushing the wedge block to move. As the wedge block moves, it drives the fixing frame and the fixing ball to rotate, thereby accurately locking the upper connecting ring of the laser cladding head. This design not only achieves effective fixing and precise positioning of the laser cladding head, but also ensures that it always remains vertical during operation, improving the stability and accuracy of the processing.

[0013] A second spring applies continuous pressure to the sliding ring, creating effective damping between the sliding ring and the laser cladding frame. This design not only enhances system stability but also significantly reduces laser cladding frame displacement caused by external vibrations or impacts, ensuring it maintains precise position and orientation throughout operation.

The first clamp 2 and the second clamp 3 are installed inside the frame 1. An electric slide rail 4 is installed on the rear side of the frame 1, and the electric slide rail 4 slides on the frame 1. An electric lifting frame 5 is connected, and a laser connecting frame 6 is slidably connected inside the electric lifting frame 5. A laser cladding frame 7 is connected to the front side of the laser connecting frame 6. A laser cladding head 701 is installed at the bottom of the laser cladding frame 7, which can clad the workpiece. A connecting ring 8 is installed on the laser cladding frame, which can fix the laser cladding head 701 to the laser cladding frame 7. A first connecting plate 9 and a second connecting plate 10 are connected to the rear side of the laser cladding frame 7. An extrusion rod 11 is installed at the bottom of the first connecting plate 9, and the extrusion rod 11 is slidably connected to the second connecting plate 10. The extrusion rod 11 is located directly above the wedge block 17, and the extrusion rod 11 can extrude the wedge block 17. A first spring 12 is connected between the bottom of the first connecting plate 9 and the top of the second connecting plate 10. A first connecting frame 13 is connected to the front side of the electric lifting frame 5. A rotating shaft 14 is symmetrically connected to the first connecting frame 13, and a fixing frame 15 is connected to the rotating shaft 14. The angle between the two fixing frames 15 in use is 30 degrees. The two fixing frames 15 can extrude and fix the connecting ring 8. Several fixing balls 16 are evenly spaced on the front side of the fixing frame 15. The inner side of the fixing frame 15 is connected to... A wedge block 17 is attached. A second connecting frame 18 is connected to the left side of the laser cladding frame 7. Positioning rods 19 are symmetrically connected to the second connecting frame 18. The positioning rods 19 can limit the laser cladding frame 7. The diameter of the positioning rods 19 is equal to the width of the first slide groove 21. A limiting frame 20 is symmetrically connected to the frame 1. The limiting frame 20 has the first slide groove 21. A second slide groove 22 is symmetrically opened on the rotating shaft 14. A sliding ring 23 is slidably connected to the second slide groove 22. A second spring 24 is connected between the bottom of the second connecting frame 18 and the top of the sliding ring 23. The second spring 24 can apply pressure to the sliding ring 23.

[0022] When this device is needed, and when positioning is required using the laser cladding head 701, the operator first places the workpiece between the first clamp 2 and the second clamp 3. Then, the operator opens the first clamp 2, causing the workpiece to rotate. Next, the electric slide rail 4 and the laser cladding head 701 are activated. The electric slide rail 4 moves the electric lifting frame 5 and all components on it. Once the electric lifting frame 5 reaches the appropriate position, the user activates it. The electric lifting frame 5 moves the laser connecting frame 6 downwards, which in turn moves the laser cladding frame 7. The laser cladding frame 7 then moves the laser cladding head 701. During the descent of the laser cladding frame 7, all components on it move. When the second connecting frame 18 moves, it moves the positioning rod 19. The positioning rod 19 passes through the first slide groove 21 and contacts the inside of the first slide groove 21. As the positioning rod 19 descends, the spring deforms, which will affect the sliding... Pressure is applied and the workpiece is fixed in place. During the movement of the first connecting plate 9 and the second connecting plate 10, the extrusion rod 11 will move downward. When the extrusion rod 11 moves to a certain position, it will extrude pressure on the wedge block 17, causing the wedge block 17 to drive the fixing frame 15 and the fixing ball 16 to rotate outward along the rotating shaft 14. During the rotation of the fixing frame 15 and the fixing ball 16, they will come into contact with the connecting ring 8 and apply pressure to it. When the laser cladding head 701 moves to the appropriate position, the electric lifting frame 5 is turned off. Then the laser cladding head 701 will come into contact with the workpiece and clad it. Then the electric slide rail 4 will drive it to move to the right, so that the laser cladding head 701 can clad the workpiece from all directions. After the cladding is completed, the operator will turn off the electric slide rail 4 and the laser cladding head 701, and then turn on the electric lifting frame 5 again, so that it will drive the laser connecting frame 6 and all its components to reset, thus completing the cladding process of the workpiece.
