[0020] Reference Figures 1 to 3 As shown, a laser cleaning and cladding composite processing device of the present invention includes a laser processing system, the laser processing system includes a first laser processing head 1 for processing the outer wall surface of the pipe 3, and a second laser processing head 2 for processing the inner wall surface of the pipe 3, the first laser processing head 1 and the second laser processing head 2 can be translated, and the pipe 3 can rotate circumferentially, so as to realize the simultaneous processing of the inner wall and the outer wall of the pipe 3; and also includes a rotation system of the pipe 3, the rotation system includes a first rotating part 4 and a second rotating part 5, the first rotating part 4 and the second rotating part 5 are used to cooperate with the pipe 3 and drive the pipe 3 to rotate circumferentially, when the first laser processing head 1 or the second laser processing head 2 processes the pipe surface area corresponding to the first rotating part 4 or the second rotating part 5, the corresponding first rotating part 4 or the second rotating part 5 is separated from the pipe 3, and the other rotating part is responsible for driving the pipe 3 to rotate. The above-mentioned first laser processing head 1 and the second laser processing head 2 can be replaceable laser cleaning heads or laser cladding heads. When the surface of the pipe 3 is processed, the laser cleaning head is first installed for cleaning, and then the laser cladding head is used for processing after cleaning. Laser cleaning heads and laser processing heads can also be arranged at a certain distance on the outside and inside of the pipe 3, so that cleaning and cladding operations can be performed without replacing the laser processing head. The laser processing system, laser cleaning head, and laser cladding head are all existing technologies and will not be described in detail here. The circumferential rotation of the pipe 3 is achieved by the first rotating part 4 and the second rotating part 5. One or more supports can be arranged in the middle of the pipe 3. Figure 2As shown, each support includes a plurality of retractable support parts 6, and the support parts 6 are supported on the outer wall of the pipe 3. Balls 603 can be provided at the position where the support parts 6 contact the pipe 3 to reduce friction. The support parts 6 form a limit while allowing the pipe 3 to rotate circumferentially, and cooperate with the first rotating part 4 or the second rotating part 5 to limit the pipe 3. The first rotating part 4 and the second rotating part 5 are structures that can be translated, and their translation can be achieved by a hydraulic or pneumatic system, or by an electric system. The first rotating part 4 and the second rotating part 5 both include a telescopic rod 8 and a support plate 7 connected to the end of the telescopic rod 8. The telescopic rod 8 can adopt a hydraulic system or a pneumatic system. The telescopic rod 8 can support the support plate 7 on the inner wall of one end of the pipe 3 or lose contact with it. The first rotating part 4 is provided with a moving rod 9, and the second rotating part 5 is provided with a moving tube 10. The connecting seat is fixed on the moving rod 9 and the moving tube 10, and the telescopic rod 8 is connected to the connecting seat. The moving rod 9 and the moving tube 10 can translate so that the support plate 7 enters or leaves the pipe 3, and the moving rod 9 and the moving tube 10 can also rotate to drive the pipe 3 to rotate. In this embodiment, the first rotating part 4 and the second rotating part 5 cooperate with the inner wall of the pipe 3, so the first laser processing head 1 can realize processing without hindrance. When the inner wall of the pipe 3 is processed, the second laser processing head 2 first processes the inner wall of one end of the pipe 3. At this time, the second rotating part 5 of the end stays outside the pipe 3. After the end is processed, the second rotating part 5 moves axially to a predetermined position, the telescopic rod 8 extends, and the second rotating part 5 rotates at the same angular velocity as the first rotating part 4, that is, the same rotation speed. The telescopic rod 8 extends until the support sheet 7 acts on the inner wall of the pipe 3. When the second laser processing head 2 moves to the other end of the pipe 3, the telescopic rod 8 of the first rotating part 4 retracts, the support sheet 7 is out of contact with the inner wall of the pipe 3, the first rotating part 4 moves away from the pipe 3, and the second laser processing head 2 processes the end smoothly. The above-mentioned first rotating part 4, the second rotating part 5, the support part 6 and the laser processing system can all be arranged on a work platform.

[0021] In the above embodiment, referring to Figure 1 As shown, the interior of the moving tube 10 of the second rotating part 5 is hollow, and the support rod passes through the moving tube 10 and enters the interior of the pipeline 3 , and the second laser processing head 2 is connected to the support rod 13 .

[0022] In the above embodiment, referring to Figure 1 As shown, a gear 11 is fixed on the outer wall of the mobile tube 10, and the gear 11 is connected to a motor through a gear set and driven to rotate by the motor. The driving motor is fixed on a support plate 12, and the mobile tube 10 is rotated in a hole connected to the support plate 12. The support plate 12 can be connected to a slider, and the slider is driven by a hydraulic system or other driving system to move axially along the pipeline 3. The slider can also move along a track set in the same direction as the axial direction of the pipeline 3.

[0023] In the above embodiment, the first rotating part 4 and the second rotating part 5 are coaxial and rotate in the same direction at the same speed. When the telescopic rods 8 of the first rotating part 4 and the second rotating part 5 are extended and retracted to separate and contact the support sheet 7 from the inner wall of the pipe 3, there will be no relative movement in the circumferential direction between the support sheet 7 and the inner wall of the pipe 3, so that no obvious disturbance will be generated during the separation or contact process.

[0024] In the above embodiment, the support portion 6 may be a roller. Figure 2 As shown, this embodiment includes an arc plate 601 and a ball 603 disposed in a groove 602 of the arc plate. The shape of the groove 602 is also arc-shaped, and the ball 603 contacts the outer wall of the pipe 3. This embodiment can cooperate with the first rotating part 4 and / or the second rotating part 5 to limit the pipe 3, and can also allow the pipe 3 to rotate freely. A support rod can be arranged below the arc plate 601, and the support rod can be retracted or moved to adapt to different diameters of the pipe 3 and facilitate the placement of the pipe 3. In order to facilitate the positioning of the initial position of the pipe 3, a clamping device for the pipe can also be provided. When the pipe is placed, it is first fixed with the clamping device, and then separated after the first rotating part and / or the second rotating part cooperate with the inner wall of the pipe.

[0025] In the above embodiment, the balls 603 are arranged in two or more rows along the axial direction of the pipe 3. Figure 3 As shown, a movable frame 604 is provided at the bottom of the groove 602, and the movable frame 604 can drive the balls 603 to move radially along the pipe 3, so that the corresponding row of balls 603 are in contact with or out of contact with the pipe 3, and is used for when the second laser processing head 2 processes the surface of the pipe area corresponding to the corresponding balls 603, the corresponding row of balls 603 is out of contact with the surface of the pipe 3, so as to prevent the cladding layer that has not been completely cooled from being affected by the extrusion of the balls.

[0026] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
