[0019] In one embodiment, as shown in Figures 1 and 2, a high-speed spherical surface laser cladding machine 10 includes: a CNC swing arm support 100, a fixture assembly 200, a laser 300, and a worktable 400; the CNC swing arm support 100 includes a first longitudinal axis support 110, a second longitudinal axis support 120, a third longitudinal axis support 130, a transverse axis support 140, a sliding block 150, and a laser cladding head 160; the first longitudinal axis support 110 and the second longitudinal axis support 120 are respectively erected on the ground on one side of the worktable 400, and the two ends of the transverse axis support 140 are respectively connected to the first longitudinal axis support 110 and the second longitudinal axis support 120. The second longitudinal axis support 120 is connected, the sliding block 150 is slidably disposed on the transverse axis support 140, the third longitudinal axis support 130 is disposed on the sliding block 150, and the laser cladding head 160 is slidably disposed on the third longitudinal axis support 130; the fixture assembly 200 includes a drive box 210 and a tooling fixture 230, the drive box 210 is disposed on the worktable 400, and one side of the drive box 210 is drivenly connected to the tooling fixture 230 through a transmission shaft 220; the laser 300 is disposed on the end of the worktable 400 away from the fixture assembly 200.

[0020] Specifically, the clamping assembly 200 is used to clamp and fix the sphere to be repaired. By setting the CNC swing arm bracket 100 on the worktable 400, the sliding block 150 slides on the second longitudinal axis bracket 120, and the laser cladding head 160 slides on the third longitudinal axis bracket 130, thereby facilitating the adjustment of the position of the laser cladding head 160 relative to the sphere fixed on the clamping assembly 200, and thus facilitating the application of coating material to the surface of the sphere by the laser cladding head 160; at the same time, the tooling fixture 230 in the clamping assembly 200 can rotate the clamped and fixed sphere, thereby facilitating the uniform application of coating material to the sphere by the laser cladding head 160. Finally, the coated surface can be rapidly laser scanned by the laser 300 to further improve the surface quality. The high-speed spherical surface laser cladding machine 10 provided in this application melts and semi-melts the coating material on the laser cladding head 160, and sprays the molten or semi-molten liquid onto the spherical surface. After rapid solidification, a metallurgically bonded surface coating is formed. The clad surface can also be rapidly laser scanned to further improve the surface quality, thus solving the problem of not being able to repair the surface of a sphere by laser cladding.

[0021] In this embodiment, the clamp assembly 200 can rotate relative to the drive box 210 via the drive shaft 220.

[0022] To facilitate the clamping and fixing of the ball within the tooling fixture 230 for rotation, in one embodiment, as shown in FIG2, the tooling fixture 230 includes a base plate 231, a first cover plate 232, a swing shaft 233, a motor (obscured in the figure, not shown), and a second cover plate 234. The base plate 231 is drivenly connected to the transmission shaft 220. The first cover plate 232 is disposed at one end of the base plate 231, and the second cover plate 234 is disposed at the other end of the base plate 231. A fixed shaft 235 extends from the first cover plate 232. The motor is disposed within the second cover plate 234 and is drivenly connected to the swing shaft 233. The fixed shaft 235 is used to fix one end of the ball, and the swing shaft 233 is used to fix the other end of the ball. Specifically, the fixed shaft 235 is rotatably disposed relative to the first cover plate 232, and the motor is used to drive the swing shaft 233 to rotate. By using the fixed shaft 235 and the swing shaft 233 to pass through the openings on both sides of the sphere, the sphere can be firmly fixed in the tooling fixture 230 for rotation.

[0023] To facilitate adjustment of the position of the fixed shaft 235 entering the ball, in one embodiment, as shown in FIG2, the fixed shaft 235 is disposed through the first cover plate 232, and a handle 236 is provided at one end of the fixed shaft 235 passing through the first cover plate 232. Specifically, by rotating the handle 236, the position of the fixed shaft 235 entering the ball can be adjusted, thereby securely fixing the ball within the tooling fixture 230.

[0024] To allow the tooling fixture 230 to rotate more effectively on the side of the drive housing 210, in one embodiment, as shown in FIG1, a bearing 221 is provided on the drive shaft 220. Specifically, by providing the bearing 221 on the drive shaft 220, the frictional force of the drive shaft 220 rotation can be reduced, thereby allowing the tooling fixture 230 to rotate more effectively on the side of the drive housing 210.

[0025] In order to adjust the position of the laser 300 on the worktable 400, in one embodiment, the worktable 400 is provided with a sliding groove (obscured in the figure, not shown), and the laser 300 is slidably disposed within the sliding groove. Specifically, by creating the sliding groove on the worktable 400 and slidably disposing of the laser 300 within the sliding groove, the position of the laser 300 relative to the fixture assembly 200 on the worktable 400 can be adjusted by sliding the laser 300 on the worktable 400, thereby facilitating the laser 300 to perform laser scanning on the sphere on the fixture assembly 200.

[0026] In order to adjust the position of the clamping assembly 200 on the worktable 400, in one embodiment, the drive housing 210 of the clamping assembly 200 is slidably disposed within the slide groove. Specifically, by sliding the clamping assembly 200 within the slide groove, the position of the clamping assembly 200 relative to the laser 300 on the worktable 400 can be adjusted by sliding the clamping assembly 200 on the worktable 400.

[0027] In one embodiment, as shown in FIG1, the first longitudinal axis support 110, the second longitudinal axis support 120, and the second longitudinal axis support 120 are arranged parallel to each other, thereby facilitating the laser 300 to perform laser scanning on the sphere on the fixture assembly 200. Specifically, the first longitudinal axis support 110 and the second longitudinal axis support 120 are both vertically arranged on the ground. This arrangement allows the CNC swing arm support 100 to be stably mounted on the ground.

[0028] In one embodiment, as shown in FIG1, a hydraulic cylinder 410 is provided at the bottom of the worktable 400. Specifically, with the above-mentioned arrangement, when the high-speed spherical surface laser cladding machine 10 is working, the worktable 400 can be lifted by the hydraulic cylinder 410. This fixing method is more convenient and faster when moving equipment.

[0029] Compared with the prior art, the present invention has at least the following advantages: The high-speed spherical surface laser cladding machine provided in this application melts and semi-melts the coating material on the laser cladding head, and sprays the molten or semi-molten liquid onto the spherical surface. After rapid solidification, a metallurgically bonded surface coating is formed. The clad surface can also be rapidly laser scanned to further improve the surface quality, thus solving the problem of not being able to repair the surface of a sphere by laser cladding.

Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
