This utility model provides a temperature-sensing laser cladding head, relating to the field of laser cladding technology. The utility model includes a laser cladding head body. By incorporating a protective device, the springs are initially contracted, allowing several protective plates to completely cover the laser head portion of the laser cladding head body. During laser cladding processing, when the robotic arm moves the cladding head to a certain position, one end of each protective plate abuts against the surface of the object to be clad. As the laser cladding head body approaches, the corresponding protective plates slide upwards through the through-holes to a certain position, causing the springs to stretch and creating a protective cover between the laser cladding head body and the area of ​​the object to be clad.

Description

Technical Field

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

[0002] A laser cladding head is a key component used in laser cladding processes. Its main function is to focus a high-power laser beam onto the surface of the workpiece, and use laser energy to melt metal powder or wire and deposit it onto the substrate surface, thereby forming a coating with special properties.

[0003] Temperature-sensing laser cladding heads use temperature sensors installed near the laser head to collect real-time temperature data of the cladding area and transmit it to the control system for processing. The system automatically adjusts the laser power, scanning speed, and material feed rate based on temperature changes, achieving closed-loop control to ensure temperature stability during the cladding process. This guarantees coating quality and uniformity. Temperature data can also be recorded for later analysis and process optimization, improving the accuracy and reliability of the entire cladding process. During the cladding process using the laser cladding head, molten material may generate spatter, which could splash onto the operator's skin, eyes, or other exposed areas, causing burns or eye irritation. Furthermore, this spatter can contaminate the working environment, increasing the difficulty of cleaning and maintenance. Utility Model Content

[0004] The technical problem this invention aims to solve is that during the cladding process of an object using a laser cladding head, the molten material may generate splatter, which may splash onto the operator's skin, eyes, or other exposed areas, causing burns or eye scalds. In addition, these splatter may contaminate the working environment and increase the difficulty of cleaning and maintenance.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a temperature detection type laser cladding head, including a laser cladding head body, a temperature sensor is provided on the outer surface of one end of the laser cladding head body, and a protective device is provided on the outer surface of one end of the laser cladding head body. The protective device can cover the laser cladding head body and the position of the object to be clad with by several protective plates and a ring frame. At the same time, the several protective plates can shrink and change length on the ring frame according to the shape and position of the object to be clad, so as to better protect it.

[0006] Preferably, the protective device includes a circular frame, with several easy-to-disassemble mechanisms provided between one side of the circular frame and the outer surface of the laser cladding head body, several through holes opened on one side of the circular frame, and one side of the circular frame abutting against one side of the laser cladding head body; several protective plates, wherein the protective plates are slidably installed in the inner wall of the through holes; and several springs, wherein the two ends of the springs are respectively fixedly installed on one side of the protective plate and one side of the circular frame.

[0007] The effect achieved by the above-mentioned components is as follows: By setting up a protective device, the spring is initially in a contracted state, so that several protective plates completely cover the laser head part of the laser cladding head body. In this way, when the robotic arm moves the cladding head to a certain position during laser cladding processing, one end of several protective plates will abut against the surface of the object to be clad. As the laser cladding head body approaches, the corresponding protective plates will slide upward in the through hole to a certain position, causing the spring to stretch and at the same time, it will also reset the protective plates, so that one side abuts against the surface of the object to be clad, thus protecting the laser cladding head body from the part of the object to be clad. In this way, the spatter generated during the cladding process will be blocked and intercepted by the protective plates, avoiding spatter and reducing harm to operators. At the same time, it will prevent spatter from polluting the working environment and reduce the difficulty of cleaning and maintenance. Temperature-sensing laser cladding heads use temperature sensors installed near the laser head to collect real-time temperature data of the cladding zone and transmit it to the control system for processing. The system automatically adjusts the laser power, scanning speed, and material feed rate according to temperature changes to achieve closed-loop control, ensuring temperature stability during the cladding process. This guarantees coating quality and uniformity. At the same time, the temperature data can be recorded for later analysis and process optimization, improving the accuracy and reliability of the entire cladding process.

[0008] Preferably, the protective device further includes several telescopic sleeves, wherein the inner wall of the telescopic sleeve is fitted onto the outer surface of the spring, and both ends are respectively fixedly installed on one side of the protective plate and one side of the ring frame.

[0009] The effect achieved by the above components is that by setting up a telescopic sleeve, the outer surface of the spring can be covered, so that during use, external dust and impurities are not easily allowed to enter the gap of the spring, thus avoiding jamming and affecting its use.

[0010] Preferably, a plurality of round beads are rotatably mounted on one side of the protective plate, wherein the round beads are located on the side of the protective plate away from the spring.

[0011] The effect achieved by the above components is that by setting the ball, the sliding friction between the protective plate and the object can be changed to rolling friction, reducing wear between the two and preventing the object surface from being scratched during the protection process.

[0012] Preferably, the easy-to-disassemble mechanism includes a locking block, one side of which is fixedly mounted on the outer surface of one end of the laser cladding head body; a magnet block, one side of which is fixedly mounted on one side of the locking block; a locking rod, one end of which is rotatably mounted on one side of the ring frame, and the other end is inserted into the inner wall of the locking block and the magnet block, the locking rod being made of iron, and one end of which is magnetically attracted to the inner wall of the magnet block; and a torsion spring, the two ends of which are respectively fixedly mounted on one side of the inner wall of one end of the locking rod and one side of the ring frame.

[0013] The effect achieved by the above-mentioned components is as follows: by setting up a disassembly mechanism, when it is necessary to replace or maintain the ring frame and protective plates, the lever can be manually rotated on the ring frame to a certain angle, which will cause the torsion spring to deform. Then, one end of the lever will be rotated out of the magnet block and aligned with the inner wall of the locking hole block. Finally, the ring frame can be pulled to one end to pull the lever out of the locking hole block, and the ring frame and several protective plates can be disassembled for easy replacement and maintenance. Similarly, the replaced protective plates and ring frame can be installed for protection.

[0014] Preferably, one end of the clamping rod is chamfered, and the chamfer is formed on the end of the clamping rod away from the ring frame.

[0015] The effect achieved by the above components is that by setting the chamfer, the area of ​​one end of the clamp rod can be reduced, making it easier to quickly align with the inner wall of the clamping block and insert it during installation, thus facilitating installation.

[0016] Preferably, a bearing is fixedly installed on the outer surface of one end of the clamp rod, and the outer ring of the bearing is fixedly installed on one side of the ring frame.

[0017] The effect achieved by the above components is that by setting bearings, the rotational wear between one end of the clamp rod and the ring frame can be reduced, which facilitates the rotation of the clamp rod and improves its service life.

[0018] The beneficial effects of this utility model are:

[0019] By incorporating a protective device, the spring is initially in a contracted state, allowing several protective plates to completely cover the laser head portion of the laser cladding head. During laser cladding, when the robotic arm moves the cladding head to a certain position, one end of each protective plate abuts against the surface of the object to be clad. As the laser cladding head approaches, the corresponding protective plate slides upwards through the through-hole to a certain position, stretching the spring and simultaneously resetting the protective plate so that one side abuts against the surface of the object to be clad. This creates a protective shield between the laser cladding head and the area to be clad, preventing spatter from being trapped and reducing harm to operators. It also prevents spatter from contaminating the working environment, reducing cleaning and maintenance difficulties. Attached Figure Description

[0027] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] Figure 1-4 The temperature-sensing laser cladding head shown includes a laser cladding head body 1. A temperature sensor 3 is provided on the outer surface of one end of the laser cladding head body 1. A protective device 2 is provided on the outer surface of one end of the laser cladding head body 1. The protective device 2 can cover the laser cladding head body 1 and the position of the object to be clad with the object through several protective plates 23 and a circular frame 21. At the same time, the several protective plates 23 can shrink and change length on the circular frame 21 according to the shape and position of the object to be clad, so as to better protect the object.

[0029] Figure 1-4The protective device 2 shown includes a ring frame 21, with several easy-to-disassemble mechanisms 27 provided between one side of the ring frame 21 and the outer surface of the laser cladding head body 1. Several through holes 22 are opened on one side of the ring frame 21, and one side of the ring frame 21 abuts against one side of the laser cladding head body 1; several protective plates 23, wherein the protective plates 23 are slidably installed in the inner wall of the through holes 22; and several springs 24, wherein the two ends of the springs 24 are respectively fixedly installed on one side of the protective plate 23 and one side of the ring frame 21. By setting up the protective device 2, the spring 24 is initially in a contracted state, so that its several protective plates 23 completely cover the laser head part of the laser cladding head body 1. In this way, when the robotic arm moves the cladding head to a certain position during the laser cladding process, one end of the several protective plates 23 will abut against the surface of the object to be clad. As the laser cladding head body 1 approaches, the corresponding protective plates 23 will slide upward in the through hole 22 to a certain position, causing the spring 24 to be stretched. At the same time, it also resets the protective plates 23, so that one side abuts against the surface of the object to be clad, thus protecting the laser cladding head body 1 from the object to be clad. In this way, the spatter generated during the cladding process will be blocked and intercepted by the protective plates 23, avoiding spatter and reducing harm to the operators. At the same time, it will prevent the spatter from polluting the working environment and reduce the difficulty of cleaning and maintenance. The temperature-sensing laser cladding head collects temperature data of the cladding zone in real time by installing a temperature sensor 3 near the laser head and transmits it to the control system for processing. The system automatically adjusts the laser power, scanning speed and material feed rate according to temperature changes to achieve closed-loop control, ensuring temperature stability during the cladding process. This guarantees coating quality and uniformity of the cladding process. At the same time, the temperature data can also be recorded for later analysis and process optimization, improving the accuracy and reliability of the entire cladding process.

[0030] Figure 1-4 The protective device 2 shown also includes several telescopic sleeves 25, the inner wall of which is fitted onto the outer surface of the spring 24, and both ends are fixedly installed on one side of the protective plate 23 and one side of the ring frame 21, respectively. By setting the telescopic sleeves 25, the outer surface of the spring 24 can be covered, so that during use, external dust and impurities are not easily allowed to enter the gaps of the spring 24, avoiding jamming and affecting use. Several round beads 26 are rotatably installed on one side of the protective plate 23, with the round beads 26 located on the side of the protective plate 23 away from the spring 24. By setting the round beads 26, the sliding friction between the protective plate 23 and the object can be changed to rolling friction, reducing wear between the two and preventing scratches on the surface of the object during protection.

[0031] Figure 1-4The disassembly mechanism 27 shown includes a locking block 271, one side of which is fixedly mounted on the outer surface of one end of the laser cladding head body 1; a magnet block 272, one side of which is fixedly mounted on one side of the locking block 271; a locking rod 273, one end of which is rotatably mounted on one side of the ring frame 21 and the other end is inserted into the inner wall of the locking block 271 and the magnet block 272, the locking rod 273 is made of iron, and one end of the locking rod 273 is magnetically attracted to the inner wall of the magnet block 272; and a torsion spring 274, both ends of which are fixedly mounted on one side of the inner wall of one end of the locking rod 273 and one side of the ring frame 21, respectively. By setting up a disassembly mechanism 27, when it is necessary to replace or maintain the ring frame 21 and the protective plate 23, the locking rod 273 can be manually rotated on the ring frame 21 to a certain angle, which will cause the torsion spring 274 to deform. Then, one end of the spring will be rotated out of the magnet block 272 and aligned with the inner wall of the locking hole block 271. Finally, the ring frame 21 can be pulled to one end to pull the locking rod 273 out of the locking hole block 271, and the ring frame 21 and several protective plates 23 can be disassembled for easy replacement and maintenance. Similarly, the replaced protective plates 23 and the ring frame 21 can be installed for protection.

[0032] Figure 1-4 The clamping rod 273 shown has a chamfer at one end, located away from the ring frame 21. This chamfer reduces the area of ​​one end of the clamping rod 273, facilitating quick alignment and insertion into the inner wall of the clamping hole block 271 during installation. A bearing 275 is fixedly mounted on the outer surface of one end of the clamping rod 273, with its outer ring fixedly mounted on one side of the ring frame 21. The bearing 275 reduces rotational wear between the clamping rod 273 and the ring frame 21, improving the clamping rod's rotation and extending its service life.

[0033] Working principle: Before using the laser cladding head body 1 to perform cladding processing on an object, the locking rod 273 on the ring frame 21 is rotated to a certain angle, causing the torsion spring 274 to deform. Then, one end of the locking rod 273 is inserted into the inner wall of the locking hole block 271. The locking rod 273 is then released, and under the reset action of the torsion spring 274, one end of the locking rod 273 is locked into the inner wall of the magnet block 272 and fixed in place. Therefore, the ring frame 21 can be fixedly installed on the laser cladding head body 1. Since the initial state of the spring 24 is contracted, its several protective plates 23 completely cover the laser head part of the laser cladding head body 1. Thus, when performing laser cladding processing, when the robotic arm... After the cladding head is moved to a certain position, one end of several protective plates 23 will abut against the surface of the object to be clad. As the laser cladding head body 1 approaches, the corresponding protective plates 23 will slide upward in the through hole 22 to a certain position, causing the spring 24 to be stretched. At the same time, the protective plates 23 will be reset, so that one side abuts against the surface of the object to be clad, thus protecting the laser cladding head body 1 from the position of the object to be clad. In this way, the spatter generated during the cladding process will be blocked and intercepted by the protective plates 23, avoiding spatter and reducing harm to the operator. At the same time, it will prevent the spatter from polluting the working environment and reduce the difficulty of cleaning and maintenance. The temperature-sensing laser cladding head collects temperature data of the cladding zone in real time by installing a temperature sensor 3 near the laser head and transmits it to the control system for processing. The system automatically adjusts the laser power, scanning speed and material feed rate according to temperature changes to achieve closed-loop control, ensuring temperature stability during the cladding process. This guarantees coating quality and uniformity of the cladding process. At the same time, the temperature data can also be recorded for later analysis and process optimization, improving the accuracy and reliability of the entire cladding process.
