Description

Technical Field

[0001] This utility model relates to the field of laser cladding technology, specifically to a laser cladding repair device for ship bearings. Background Technology

[0002] In modern shipbuilding and maintenance, bearings, as critical power transmission support components, directly affect the safety, operational efficiency, and maintenance costs of the ship. As ship designs become increasingly larger, faster, and more complex, the loads bearings bear under operating conditions are constantly increasing, leading to a rise in the risks of wear, fatigue, corrosion, and damage. Traditional bearing repair methods often employ welding, machining, or coating techniques, but these methods have several drawbacks. Welding easily generates a large heat-affected zone, which can cause deformation, cracks, and internal defects, severely impacting repair quality. Machining repairs are limited by the complexity of the parts' shapes, making it difficult to restore the original performance and dimensions. While coating technology is simple, it suffers from poor adhesion and insufficient wear resistance, failing to meet the requirements of ship bearings operating in high-intensity environments. Laser cladding, as a high-energy beam rapid local heating technology, possesses high energy density and excellent molten pool control. Laser cladding can restore the original performance of ship bearings, ensuring that the dimensions and performance of the repaired bearing meet the stringent requirements of ship operation. With the shipbuilding industry continuously improving maintenance efficiency and repair quality, the development of laser cladding repair devices specifically for ship bearings has become particularly important.

[0003] Ship bearings typically have complex structures, and traditional laser cladding repair devices cannot handle complex repair paths.

[0004] Therefore, this application proposes a laser cladding repair device for ship bearings. Utility Model Content

[0005] The purpose of this invention is to provide a laser cladding repair device for ship bearings to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] A blood sample storage device includes: a base, a clamping seat, a clamping adjustment assembly, an adjustment assembly, and a laser cladding head. The base has a sliding groove and a through hole. The clamping adjustment assembly includes: a first motor, a slanted disc, an angle rod, and a swing rod. The first motor is fixedly installed inside the base. The slanted disc is fixedly connected to the output end of the first motor. The angle rod is rotatably connected to the base at its middle position. Rotary wheels are installed at both ends of the angle rod, and the wheels are in contact with the slanted disc. The swing rod passes through the through hole and is fixedly connected to the angle rod at one end and to the clamping seat at the other end. The adjustment assembly is slidably connected to the base. The laser cladding head is rotatably connected to the adjustment assembly.

[0008] In the above technical solution, the clamping seat is used to place the workpiece to be repaired. The first motor is started, which drives the inclined disc to rotate. The two rotating wheels rotate along the inclined disc, forcing the angle between the angle rod and the base to change. This causes the swing rod to move along the through hole, which in turn changes the angle of the workpiece on the clamping seat, thus improving the practicality of the repair device.

[0009] A further improvement of this utility model's technical solution lies in the following: the adjustment assembly includes a slider, an adjusting rod, and a first electric telescopic rod. The slider is installed within a groove. The adjusting rod is rotatably connected to the slider. The first electric telescopic rod is rotatably connected to the adjusting rod. One end of the first electric telescopic rod is rotatably connected to the laser cladding head.

[0010] By adopting the above technical solution, the angle between the adjusting rod and the slider, the angle between the first electric telescopic rod and the adjusting rod, and the length of the first electric telescopic rod and the included angle between the laser cladding head and the first electric telescopic rod can be adjusted so that the laser cladding head can repair workpieces of different shapes using different angles, further improving the practicality of the repair device.

[0011] A further improvement of this utility model is that it also includes two second electric telescopic rods. These two second telescopic rods are rotatably connected to the clamping seat. The two second telescopic rods are symmetrically installed inside the clamping seat. A clamping block is fixedly installed at one end of the inner side of each of the two second electric telescopic rods.

[0012] Using the above technical solution, the second electric telescopic rod can clamp the workpiece to be repaired through two clamping blocks. Since the two second electric telescopic rods are rotatably connected to the clamping base, the clamped workpiece can be rotated and adjusted.

[0013] A further improvement of this utility model is that it also includes a locking rod. One end of the locking rod is coaxially and fixedly connected to one of the electric telescopic rods. The screw is rotatably connected to the clamping seat.

[0014] A further improvement of this utility model is that it also includes a locking ring. The locking ring is screwed to the locking rod.

[0015] Using the above technical solution, when the position needs to be fixed and rotation is not required, rotating the locking ring causes it to contact the clamping seat. The friction between the locking ring and the clamping seat then locks the rod in place, ultimately fixing the two electric telescopic rods in place so they cannot rotate. This further enhances the practicality of the repair device.

[0016] A further improvement of this utility model is that it also includes a threaded rod. The threaded rod is installed inside the slide groove. The threaded rod is screwed to the slide block.

[0017] A further improvement of this utility model is that it also includes a second motor. The second motor is fixedly connected to the base. The output end of the second motor is fixedly connected to the threaded rod.

[0018] The above technical solution involves starting a second motor, which drives the screw to rotate, thereby causing the slider to move along the groove. This further increases the path selection of the laser cladding head and improves the practicality of the repair device.

[0019] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0020] 1. This utility model provides a laser cladding repair device for ship bearings. When the first motor is started, the first motor drives the inclined disc to rotate. The two rotating wheels rotate along the inclined disc, which forces the angle between the angle rod and the base to change. This causes the swing rod to drive the clamping seat to move along the through hole, and finally changes the angle of the workpiece on the clamping seat, thus improving the practicality of the repair device.

[0021] 2. This utility model provides a laser cladding repair device for ship bearings. The angle of the clamping seat can be adjusted by the clamping adjustment component. With the cooperation of the locking ring and locking rod, the clamped workpiece can be rotated and locked. With the power distribution of the adjustment component, threaded rod and second motor, the applicability of the repair device to complex repair paths is greatly improved.

[0030] The present invention will be further described in detail below with reference to embodiments:

[0031] Example 1

[0032] like Figures 1-6 As shown, this utility model provides a laser cladding repair device for ship bearings, including a base 1, a clamping seat 5, a clamping adjustment component 13, a laser cladding head 8, and may also include an adjustment component 7, two second electric telescopic rods 9, a locking rod 11, a locking ring 12, a threaded rod 3, and a second motor 6.

[0033] The clamping and adjusting assembly 13 includes: a first motor 131, an inclined disc 132, an angle rod 133, and a swing rod 135. The first motor 131 is fixedly installed inside the base 1. The inclined disc 132 is fixedly connected to the output end of the first motor 131. The angle rod 133 is rotatably connected to the base 1 at its middle position. Rotary wheels 134 are respectively installed at both ends of the angle rod 133. The rotary wheels 134 are in contact with the inclined disc 132. The swing rod 135 passes through the through hole 4 and is fixedly connected to the angle rod 133 at one end, and fixedly connected to the clamping seat 5 at the other end. The adjusting assembly 7 is slidably connected to the base 1. The laser cladding head 8 is rotatably connected to the adjusting assembly 7. The clamping seat 5 is used to hold the workpiece to be repaired. The first motor 131 is started, driving the inclined disc 132 to rotate. Two rotating wheels 134 rotate along the inclined disc 132, forcing a change in the angle between the angle rod 133 and the base 1. This causes the swing rod 135 to move along the through hole 4, ultimately changing the angle of the workpiece on the clamping seat 5, thus improving the practicality of the repair device. Except for the motor in the clamping assembly, other components can be made of high-manganese steel. High-manganese steel is a special alloy steel with excellent wear resistance and impact toughness, mainly composed of manganese and with a high carbon content. High-manganese steel has excellent wear resistance. After impact and friction, manganese steel forms a fine, hardened carbide layer, creating a self-reinforcing cast steel wear-resistant layer on the surface. This carbide layer not only enhances surface hardness but also resists wear under high friction conditions, extending the service life of mechanical parts. This significantly reduces the frequency of mechanical maintenance and replacement, lowering production costs. High-manganese steel also has excellent impact toughness. Its structure can absorb a large amount of energy when subjected to huge impact loads, preventing component damage due to brittle fracture. This ensures that the equipment maintains stable performance during operation. Under friction or impact stress, the surface gradually hardens, forming a hard skin that enhances its wear resistance. In areas without continuous friction, the material retains a certain degree of toughness and is not prone to brittle fracture, greatly satisfying the dual requirements of fatigue resistance and impact resistance for mechanical components. High manganese steel has a relatively simple manufacturing process, with casting and forging being relatively easy and cost-effective.

[0034] The adjustment assembly 7 includes: a slider 71, an adjusting rod 72, and a first electrically operated telescopic rod 73. The slider 71 is installed within the slide groove 2. The adjusting rod 72 is rotatably connected to the slider 71. The telescopic rod is rotatably connected to the adjusting rod 72. One end of the telescopic rod is rotatably connected to the laser cladding head 8. By adjusting the angle between the adjusting rod 72 and the slider 71, the angle between the first electrically operated telescopic rod 73 and the adjusting rod 72, and the length of the first electrically operated telescopic rod 73 and the included angle between the laser cladding head 8 and the first electrically operated telescopic rod 73, the laser cladding head 8 can repair workpieces of different shapes using different angles, further improving the practicality of the repair device. The angles between the components of the adjustment assembly 7 can be maintained with high static friction.

[0035] The two second electric telescopic rods are rotatably connected to the clamping seat 5. The two second telescopic rods are symmetrically installed inside the clamping seat 5. A clamping block 10 is fixedly installed at one end of the inner side of each of the two second electric telescopic rods 9. One end of a locking rod 11 is coaxially fixedly connected to one of the electric telescopic rods. The locking rod 11 is rotatably connected to the clamping seat 5. A locking ring 12 is screwed to the locking rod 11. The two second electric telescopic rods 9 can clamp the workpiece to be repaired through the two clamping blocks 10. Because the two second electric telescopic rods 9 are rotatably connected to the clamping seat 5, the clamped workpiece can be rotated and adjusted. When the position needs to be fixed and rotation is not required, the locking ring 12 is rotated, causing the locking ring 12 to contact the clamping seat 5. Through the friction between the locking ring 12 and the clamping seat 5, the locking rod 11 is fixed, thus fixing the two electric telescopic rods and preventing them from rotating. This further improves the practicality of the repair device.

[0036] The threaded rod 3 is installed inside the slide groove 2. The threaded rod 3 is screwed to the slider 71. The second motor 6 is fixedly connected to the base 1. The output end of the second motor 6 is fixedly connected to the threaded rod 3. When the second motor 6 is started, it drives the screw to rotate, thereby causing the slider 71 to move along the slide groove 2, further increasing the path selection of the laser cladding head 8 and further improving the practicality of the repair device. The first motor 131 and the second motor 6 can be servo motors. Servo motors are equipped with high-resolution encoders or rotary transformers, which can achieve micron-level positioning accuracy. Their closed-loop control system ensures that mechanical parts can accurately reach the set angle or position, greatly improving working accuracy. Servo motors have good response speed and can quickly identify and adjust to the target position or speed. This rapid response capability ensures that the mechanical system can complete dynamic motion and complex path tracking in a short time, improving production efficiency and reducing waiting time. The servo system can provide the required torque under different working conditions and support changes in mechanical load. Effective torque control ensures smooth mechanical operation, avoids vibration and impact, extends equipment life, and ensures the stability of the working process. Servo motors can automatically adjust the output energy according to load and motion requirements to achieve high-efficiency operation. This not only reduces energy consumption, but also reduces equipment cooling and maintenance costs.

[0037] The working principle of this laser cladding repair device for ship bearings will be explained in detail below.

[0038] like Figures 1-6As shown, activating the two second electric telescopic rods 9 allows the workpiece to be repaired to be clamped via the two clamping blocks 10. Since the two second electric telescopic rods 9 are rotatably connected to the clamping seat 5, the clamped workpiece can be rotated for adjustment. When the two second electric telescopic rods 9 do not need to rotate, rotating the locking ring 12 causes it to contact the clamping seat 5, fixing it in place from the two second electric telescopic rods 9. When the angle of the clamping seat 5 needs adjustment, activating the first motor 131 drives the inclined disc 132 to rotate. The two rotating wheels 134 rotate along the inclined disc 132, forcing a change in the angle between the angle rod 133 and the base 1. This causes the swing rod 135 to move along the through hole 4, ultimately changing the angle of the workpiece on the clamping seat 5, thus improving the practicality of the repair device. By adjusting the angle between the adjusting rod 72 and the slider 71, the angle between the first electric telescopic rod 73 and the adjusting rod 72, and the length of the first electric telescopic rod 73 and the included angle between the laser cladding head 8 and the first electric telescopic rod 73, the laser cladding head 8 can repair workpieces of different shapes using different angles, further improving the practicality of the repair device. Starting the second motor 6 drives the screw to rotate, causing the slider 71 to move along the groove 2, further increasing the path selection of the laser cladding head 8 and further improving the practicality of the repair device. In summary, this repair device is characterized by its simple and flexible operation.

[0039] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
