Description

Technical Field

[0001] This utility model belongs to the field of laser cladding head technology, and in particular relates to an adjustable laser cladding head. Background Technology

[0002] The laser cladding head is the core component of laser cladding technology. It is mainly used to melt metal powder or wire and deposit it on the surface of the substrate to form a high-quality coating or repair layer.

[0003] When coating or repairing pipe fittings, a horizontally moving cladding head is typically used to move across the pipe surface to apply coating or repair. However, this horizontal movement method can lead to blind spots during the repair or coating process. To address this, we propose an adjustable rotating laser cladding head to overcome the shortcomings of existing technologies. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable laser cladding head that can rotate while moving, thereby avoiding blind spots in the repair or coating process and solving the aforementioned technical problems.

An electric telescopic rod is fixedly connected to one side of the machine tool. The telescopic end of the electric telescopic rod passes through the machine tool and extends to the inner cavity of the machine tool, where a three-jaw chuck is fixedly connected. A three-jaw chuck is fixedly connected to the right side of the inner cavity of the machine tool at a position corresponding to the three-jaw chuck. A drive structure is provided on the back of the machine tool. A support seat is provided on the front of the drive structure. A through groove for movement with the support seat is opened on the back of the inner cavity of the machine tool. A servo motor is fixedly connected to the inner cavity of the support seat. A drive gear is fixedly connected to the output shaft of the servo motor. A support cylinder is fixedly connected to the end face of the front of the support seat. A cylinder body is rotatably connected to the inner surface of the support cylinder through a bearing. A driven gear is fixedly connected to the surface of the cylinder body. The driven gear meshes with the drive gear. The laser head is embedded and fixedly connected to the inner surface of the cylinder body.

[0006] Preferably, the drive structure includes a concave frame fixedly connected to the back of the machine tool, a rotary motor fixedly connected to one end face of the concave frame, a threaded rod fixedly connected to the output shaft of the rotary motor, the threaded rod being rotatably connected to the back of the inner cavity of the concave frame via a bearing, a threaded sleeve being threadedly connected to the surface of the threaded rod, and the front of the threaded sleeve being fixedly connected to the back of the support seat.

[0010] The beneficial effects of this utility model are:

[0011] 1. This utility model uses a three-jaw clamp to grip one side of the pipe surface, allowing the pipe to pass through the inner surface of the cylinder. An electric telescopic rod moves the pipe, clamping the other side of the pipe surface onto the inner surface of the three-jaw clamp, thus fixing the pipe. A laser head repairs or coats the pipe.

A three-jaw chuck 2 4 is fixedly connected to the right side of the inner cavity of the machine tool 1 at a position corresponding to the three-jaw chuck 1 3. A drive structure is provided on the back of the machine tool 1, comprising a concave frame 13 fixedly connected to the back of the machine tool 1. A rotary motor 14 is fixedly connected to one end face of the concave frame 13. A threaded rod 15 is fixedly connected to the output shaft of the rotary motor 14. The back of the inner cavity of the concave frame 13 is rotatably connected to the threaded rod 15 via a bearing. A threaded sleeve 16 is threadedly connected to the surface of the threaded rod 15. The front of the threaded sleeve 16 is fixedly connected to the back of the support seat 5. A guide block is fixedly connected to one side of the threaded sleeve 16. The inner cavity of the concave frame 13 has a guide groove that slides to match the guide block. The threaded rod 15 is rotated by the rotary motor 14, which in turn rotates the threaded sleeve 16 on its surface, thereby causing the support seat 5 to move left and right. The movement of the support seat 5 is guided by the guide block sliding on the inner surface of the guide groove. The support seat 5 is provided on the front of the drive structure. The back of the inner cavity of the machine tool 1 is... A through groove 6 is provided on the front of the support base 5, which moves with the support base 5. The support base 5 passes through the through groove 6 and extends into the interior of the machine tool 1. A servo motor 7 is fixedly connected to the inner cavity of the support base 5. A drive gear 8 is fixedly connected to the output shaft of the servo motor 7. A support cylinder 9 is fixedly connected to the end face of the front of the support base 5. A cylinder body 11 is rotatably connected to the inner surface of the support cylinder 9 through a bearing. A driven gear 10 is fixedly connected to the surface of the cylinder body 11. The driven gear 10 meshes with the drive gear 8. The laser head 12 is embedded and fixedly connected to the inner surface of the cylinder body 11. The three-jaw chuck 3 clamps one side of the tube surface, so that the tube passes through the inner surface of the cylinder body 11. The laser head 12 is driven by the electric telescopic rod 2. The tube moves, causing the other side of the tube surface to be clamped onto the inner surface of the three-jaw clamp 4, thus fixing the tube. The laser head 12 then repairs or coats the tube. Simultaneously, the drive structure moves the support base 5, which in turn moves the servo motor 7 and the support cylinder 9. The servo motor 7 drives the drive gear 8 to rotate, which in turn drives the driven gear 10 to rotate. This causes the cylinder 11 to rotate on the inner surface of the support cylinder 9 via bearings, which in turn rotates the laser head 12. This achieves both movement and rotation adjustment, avoiding blind spots in the repair or coating process.

[0025] Example 2:

[0026] Figure 1-4This invention illustrates an adjustable laser cladding head according to an embodiment of the present invention, comprising a laser head 12 disposed inside a machine tool 1. An electric telescopic rod 2 is fixedly connected to one side of the machine tool 1. The telescopic end of the electric telescopic rod 2 passes through the machine tool 1 and extends into the inner cavity of the machine tool 1, where a three-jaw chuck 1 3 is fixedly connected. A three-jaw chuck 2 4 is fixedly connected to the right side of the inner cavity of the machine tool 1 at a position corresponding to the three-jaw chuck 1 3. A drive structure is provided on the back of the machine tool 1, and a support base 5 is provided on the front of the drive structure.

A cylinder body 11 is rotatably connected to the inner surface of the support cylinder 9 through a bearing. The cylinder body 11 has a hollow structure. There are no fewer than two laser heads 12. By setting the cylinder body 11 to have a hollow structure, it is convenient for the tube to pass through. A driven gear 10 is fixedly connected to the surface of the cylinder body 11. The driven gear 10 meshes with the drive gear 8. The laser head 12 is embedded and fixedly connected to the inner surface of the cylinder body 11.

[0027] Working Principle: In use, the three-jaw clamp 3 clamps one side of the pipe surface, allowing the pipe to pass through the inner surface of the cylinder 11. The pipe is moved by the electric telescopic rod 2, so that the other side of the pipe surface is clamped on the inner surface of the three-jaw clamp 4, thus fixing the pipe. The laser head 12 repairs or coats the pipe. At the same time, the rotary motor 14 drives the threaded rod 15 to rotate, which in turn drives the threaded sleeve 16 on its surface to rotate, thereby moving the support base 5 left and right, which in turn drives the servo motor 7 to move, and also drives the support cylinder 9 to move. Simultaneously, the servo motor 7 drives the drive gear 8 to rotate, which in turn drives the driven gear 10 to rotate, thereby causing the cylinder 11 to rotate on the inner surface of the support cylinder 9 through the bearing, which in turn drives the laser head 12 to rotate. This achieves both movement and rotation adjustment, avoiding blind spots in repair or coating.
