Description

Technical Field

[0001] This utility model relates to the field of quick-release structure technology, and in particular to a quick-release laser cladding head. Background Technology

[0002] In practical applications of laser cladding technology, the installation and angle adjustment of the cladding head significantly impact process efficiency and quality. Currently, some quick-release structures use ball-bearing engagement. Due to design requirements or long-term use, the balls and slots are prone to wear, leading to gaps at the connection between the cladding head and the equipment, thus affecting the stability of the cladding head during operation. Furthermore, traditional cladding heads, when installed on a three-dimensional motion platform, often require complex multi-axis linkage mechanisms for angle adjustment, or multiple disassemblies and manual calibrations. This cumbersome process makes it difficult to quickly adapt to the multi-angle cladding requirements of some simple workpieces. Utility Model Content

[0003] To address the shortcomings of existing technologies, this invention provides a quick-release laser cladding head, which has the advantages of stable connection, convenient assembly and disassembly, and flexible angle adjustment, thus solving some of the problems mentioned in the background technology.

[0004] This utility model provides the following technical solution: a quick-release laser cladding head, including a laser cladding machine head, an adjusting seat, and a positioning seat. A connecting pipe is fixedly connected to the upper right end of the laser cladding machine head. A sleeve is fixedly connected to the middle of the left end of the adjusting seat. The connecting pipe is slidably connected inside the sleeve. A shaped sliding sleeve is slidably fitted onto the outer side of the sleeve near the middle. Evenly distributed locking rods are slidably connected through the sleeve near the left side. One end of the locking rod facing outward is inclined, and a T-shaped slider is fixedly connected to the middle. The left end of the shaped sliding sleeve fits against the locking rod and is provided with evenly distributed sliding grooves. The T-shaped slider is slidably connected inside the sliding grooves. Evenly distributed locking holes are provided on the connecting pipe, and the locking rods and locking holes are adapted to each other.

[0005] Furthermore, a retaining ring is fixedly sleeved on the outer side of the connecting pipe near the left end, and a slide block is fixedly installed on the left end of the adjusting seat on the outer side of the sleeve. A return spring is installed on the outer side of the sleeve between the slide block and the irregularly shaped slide sleeve. The structure is simple, improves the standardization and convenience of operation, and at the same time provides a limiting effect on the irregularly shaped slide sleeve through the return spring.

[0006] Furthermore, a main universal ball is fixedly installed at the right end of the sleeve, and a ball seat is fixedly installed at the middle of the left end of the positioning seat. The main universal ball and the ball seat are rotatably connected, that is, the angle between the adjusting seat and the positioning seat can be adjusted at any angle with the main universal ball as the center.

[0007] Furthermore, auxiliary universal balls are rotatably installed at each of the four corners of the adjusting seat, and an adjusting screw is threaded through and connected to the center of each auxiliary universal ball. The rotatable connection between the auxiliary universal balls and the adjusting seat ensures the rationality of the structural design.

[0008] Furthermore, ball rod assemblies are fixedly installed on the left end of the positioning seat near the four corners, and threaded cylinders are rotatably installed on the left end of each ball rod assembly. The right end of the adjusting screw is threadedly connected to the inside of the threaded cylinder. The rotatable connection between the threaded cylinder and the positioning seat through the ball rod assembly ensures that the structure can adaptively rotate when the position between the adjusting screw and the threaded cylinder changes, thus avoiding structural conflicts.

[0009] The advantages of this utility model are as follows:

[0010] 1. By using the connecting tube and sleeve in conjunction with the linkage structure of the irregular sliding sleeve, T-shaped slider and clamping rod, the laser cladding head can be quickly installed and disassembled. During operation, simply sliding the irregular sliding sleeve is enough to complete the locking and disassembly. Compared with the traditional ball joint locking method, it effectively ensures the fit between the clamping rod and the clamping hole, avoids the generation of connection gaps, improves the stability of the cladding head during use, shortens the equipment debugging and replacement time, and improves work efficiency.

[0011] 2. By utilizing the main universal ball, ball seat, auxiliary universal ball and ball rod assembly, the distance between the adjusting seat and the positioning seat can be changed by rotating the adjusting screw, thus realizing flexible multi-angle adjustment of the laser cladding head. This design does not require complex multi-axis linkage or frequent disassembly and calibration, and is particularly suitable for cladding operations on rotating workpieces at a fixed angle. It can be adjusted at any angle within a certain range, greatly enhancing the equipment's flexibility and process adaptability. Attached Figure Description

[0017] 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.

[0018] Please see Figures 1-4 A quick-release laser cladding head includes a laser cladding head 1, an adjusting base 3, and a positioning base 15. A connecting pipe 2 is fixedly connected to the upper right end of the laser cladding head 1. A sleeve 4 is fixedly connected to the middle of the left end of the adjusting base 3. The connecting pipe 2 is slidably connected inside the sleeve 4. A shaped sliding sleeve 5 is slidably fitted onto the outer side of the sleeve 4 near the middle. Evenly distributed locking rods 6 are slidably connected through the sleeve 4 near the left side. One end of the locking rod 6 facing outwards is... A T-shaped slider 7 is fixedly connected to the inclined surface and the middle. The left end of the irregularly shaped sliding sleeve 5 is fitted with the locking rod 6 and is provided with evenly distributed sliding grooves 8. The T-shaped slider 7 is slidably connected inside the sliding grooves 8. The connecting tube 2 is provided with evenly distributed locking holes 9. The locking rod 6 is adapted to the locking holes 9. A retaining ring 10 is fixedly sleeved on the outside of the connecting tube 2 near the left end. A sliding seat 11 is fixedly installed on the left end of the adjusting seat 3 on the outside of the sleeve 4. The outside of the sleeve 4 is connected to the sliding seat 11 and the irregularly shaped sliding sleeve 5. A return spring 12 is installed between the sliding sleeves 5. During installation, the connecting tube 2 on the laser cladding head 1 is inserted into the sleeve 4, aligning the locking hole 9 with the locking rod 6. At the same time, the irregular sliding sleeve 5 is held and slid to the right. Sliding the irregular sliding sleeve 5 to the right allows the T-shaped slider 7 to slide upward inside the sliding groove 8, thereby lifting the locking rod 6. When the sleeve 4 reaches the retaining ring 10, the irregular sliding sleeve 5 is released and the return spring 12 rebounds, thereby driving the irregular sliding sleeve 5 to slide to the left to reset. The T-shaped slider 7 will slide downward, eventually allowing the locking rod 6 to descend and be inserted into the locking hole 9, thus completing the installation and fixation of the laser cladding head 1. Disassembly is similar; after sliding the irregular sliding sleeve 5 to the right, the connecting tube 2 can be directly removed. The operation is simple and quick. Compared with some quick-release structures that currently use ball joints, this device ensures the fit between the locking rod 6 and the locking hole 9, avoiding gaps and effectively improving the stability of the laser cladding head 1 during use.

[0019] Please see Figures 1-3 A main universal ball joint 13 is fixedly installed on the right end of the sleeve 4, and a ball seat 14 is fixedly installed at the middle of the left end of the positioning seat 15. The main universal ball joint 13 and the ball seat 14 are rotatably connected. Auxiliary universal ball joints 16 are rotatably installed at each of the four corners of the adjusting seat 3. An adjusting screw 17 is threaded through and connected to the middle of the interior of each auxiliary universal ball joint 16. A ball rod assembly 18 is fixedly installed near each of the four corners of the left end of the positioning seat 15. A threaded cylinder 19 is rotatably installed at the left end of each ball rod assembly 18. The right end of the adjusting screw 17 is threaded into the interior of the threaded cylinder 19. The device can be installed on a three-dimensional motion platform such as a robotic arm or machine tool through the positioning seat 15. Since the middle position of the adjusting seat 3 and the positioning seat 15 is connected... The main universal ball 13 and ball seat 14 are movably installed, and at the same time play a certain role in limiting and supporting. Meanwhile, the auxiliary universal ball 16, the adjusting seat 3, the ball rod assembly 18 and the threaded cylinder 19 can be adaptively rotated within a certain range. Therefore, by rotating the adjusting screw 17, displacement can be made between it and the auxiliary universal ball 16, and further, it can be moved to the right or left inside the threaded cylinder 19. By changing the distance between the adjusting seat 3 and the positioning seat 15 at the corresponding corner, the cladding angle of the laser cladding head 1 can be adjusted. It is particularly suitable for cladding operations on rotating workpieces at a fixed angle. It is convenient and flexible to use, and can be adjusted at any angle within a certain range.

[0020] Working principle: During installation, insert the connecting tube 2 on the laser cladding head 1 into the sleeve 4, aligning the locking hole 9 with the locking rod 6. Simultaneously, hold the irregular sliding sleeve 5 and slide it to the right. Sliding the irregular sliding sleeve 5 to the right causes the T-shaped slider 7 to slide upwards inside the sliding groove 8, thereby lifting the locking rod 6. When the sleeve 4 reaches the retaining ring 10, release the irregular sliding sleeve 5, and the return spring 12 rebounds, causing the irregular sliding sleeve 5 to slide to the left to reset. The T-shaped slider 7 will then slide downwards, ultimately lowering the locking rod 6 and inserting it into the locking hole 9, thus completing the installation and fixing of the laser cladding head 1. Disassembly is similar; after sliding the irregular sliding sleeve 5 to the right, the connecting tube 2 can be directly removed. Further... The device can be installed on a three-dimensional motion platform such as a robotic arm or machine tool via the positioning seat 15. Since the middle position of the adjusting seat 3 and the positioning seat 15 is movably installed through the main universal ball 13 and the ball seat 14, it also plays a certain role in limiting support. At the same time, the auxiliary universal ball 16 can be adaptively rotated and adjusted within a certain range with the adjusting seat 3, the ball rod assembly 18 and the threaded cylinder 19. Therefore, by rotating the adjusting screw 17, it can be displaced between itself and the auxiliary universal ball 16, and further move to the right or left inside the threaded cylinder 19. By changing the distance between the adjusting seat 3 and the positioning seat 15 at the corresponding corner, the cladding angle of the laser cladding head 1 can be adjusted.
