Description

Technical Field

[0001] This utility model mainly relates to the field of laser cladding technology, specifically a rapid preparation device for laser cladding coating on self-lubricating bushings. Background Technology

[0002] Laser cladding is an advanced surface modification technology, also known as laser welding or laser cladding. It uses a high-energy-density laser beam as a heat source to melt and rapidly solidify a specific coating material (usually metal or alloy powder or wire), thereby forming a coating with specific properties (such as wear resistance, corrosion resistance, high temperature resistance, self-lubrication, etc.) on the surface of the substrate material.

[0003] In existing technologies, laser cladding equipment typically lacks precise position and angle adjustment capabilities. Most devices have fixed laser and nozzle positions, or can only achieve simple linear movement, making operation cumbersome and time-consuming. Furthermore, the laser incident angle cannot be controlled, easily leading to uneven cladding coating thickness, poor surface quality, and other problems that affect coating performance and lifespan. Utility Model Content

[0004] This invention provides a rapid preparation device for laser cladding coating of self-lubricating bushings to solve the technical problems mentioned in the background art.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

A fixing plate is fixedly installed on the top of the base plate on the side away from the mounting plate, and a fixing component is provided on one side of the fixing plate. A connecting plate is fixedly connected to the top of both the mounting plate and the fixing plate, and a movable component is provided between the two connecting plates.

[0007] An angle adjustment component is provided on one side of the movable plate.

[0008] Preferably, the rotating assembly includes a first servo motor and a rotating block. The first servo motor is fixedly mounted on one side of the mounting plate, and the rotating block is connected to the other side of the mounting plate via a rotating shaft.

[0009] Preferably, the fixing component includes a hydraulic rod and a fixing block. The hydraulic rod is fixedly installed on one side of the fixing plate, and the actuating end of the hydraulic rod is connected to the fixing block through a rotating shaft.

[0010] Preferably, the moving component includes a threaded rod and a second servo motor. The threaded rod is connected between the two connecting plates via a rotating shaft. One end of the threaded rod is connected to the moving plate via a threaded connection. The second servo motor is fixedly installed on one side of the connecting plate at the top of the mounting plate, and the output shaft end of the second servo motor is connected to one end of the threaded rod.

[0011] Preferably, the angle adjustment assembly includes a third servo motor, a drive gear, a driven gear, a connecting block, a laser, a nozzle, a powder feeding port, a laser channel, and a powder feeding channel. The third servo motor is fixedly installed on one side of the moving plate, and the drive gear is connected to the other side of the moving plate via a rotating shaft. One end of the drive gear is connected to the output shaft of the third servo motor. The driven gear is connected to the drive gear on the other side of the moving plate via a rotating shaft.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. The second servo motor drives the threaded rod to rotate, thereby realizing the movement and positioning of the moving plate. At the same time, the third servo motor drives the active gear and the driven gear to mesh and transmit power, precisely adjusting the incident angle of the laser and the nozzle. This enables precise control of the laser cladding position and angle, allowing the device to adapt to the cladding requirements of bushings of different sizes, thus improving the versatility and flexibility of the equipment.

[0015] 2. The fixed block and the rotating block are driven by a hydraulic rod to achieve stable clamping of the bushing. At the same time, the rotating block is driven by the first servo motor to rotate, so that the bushing rotates at a constant speed during the cladding process. This ensures that the laser cladding coating is evenly covered on the surface of the bushing, which significantly improves the uniformity and quality stability of the coating.

The fixing component 6 is responsible for fixing the bushing during the laser cladding process, ensuring the bushing remains stable. A connecting plate 7 is fixedly connected to one side of the top of both the mounting plate 3 and the fixing plate 5. A moving component 8 is provided between the two connecting plates 7.

The second servo motor 802 is fixedly installed on one side of the connecting plate 7 at the top of the mounting plate 3. The output shaft of the second servo motor 802 is connected to one end of the threaded rod 801. The output shaft of the second servo motor 802 drives the threaded rod 801 to rotate, thereby driving the moving component 801. The movable plate 2 moves axially. Both ends of the movable plate 2 are connected to limit rods 10 through mounting holes, and both ends of the two limit rods 10 are fixedly connected to one side of the two connecting plates 7.

[0026] In use, the bushing is fitted onto the rotating shaft block, and the hydraulic rod 601 is driven so that its actuator drives the rotating block 402 to move towards the fixed block 602 to clamp and fix the bushing. After fixing, the first servo motor 401 is driven so that its output shaft drives the rotating block 402 to rotate, which in turn drives the fixed block 602 to rotate, providing the necessary rotational motion for laser cladding. At the same time, the second servo motor 802 is driven so that its output shaft drives the threaded rod 801 to rotate, which in turn moves the moving plate 2 to the appropriate cladding position. After adjustment, the third servo motor 901 is driven so that its output shaft drives the drive gear 902 to rotate, which in turn drives the driven gear 903 to rotate, causing the laser 905 and the nozzle 906 to rotate, thereby changing the incident angle of the laser cladding.
