[0017] S5: When the universal clamp contacts the additive material, the positioning frame contacts the outer wall of the additive material, and then the semi-arc chuck and the semi-arc holder will adaptively adjust according to the shape of the additive material, thereby preventing damage to the additive material during the clamping process.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] In the present invention, when additive manufacturing is performed, two laser cladding heads arranged on the screw slide are used to perform additive manufacturing on the cradle turntable.

Through this arrangement, the dual laser cladding device can contact with the transmission device after the additive manufacturing is completed, and then through this arrangement, the additive material can be quickly clamped and limited after the additive manufacturing, so as to achieve the clamping and unloading of the additive material and improve the efficiency of the additive manufacturing.

[0021] In the present invention, when the pushing block drives the pushing shell to move, the pushing shell moves in the direction of the additive material, and the clamping block in the pushing shell drives the universal clamp to contact the additive material. After the universal clamp contacts the additive material, the clamping block will slide in the pushing shell driven by the pushing shell, and at this time the pushing shell will continue to move in the direction of the additive material, thereby driving the embedded plate to be inserted into the bottom of the additive material, so that the additive material is separated from the cradle turntable, and the clamping limit of the additive material during the additive manufacturing process is realized while the separation of the bottom of the additive material and the cradle turntable is realized, which is convenient for subsequent operators to take the additive material.

[0051] S4: When the push block 52 drives the push shell 61 to move, the push shell 61 moves in the direction of the additive material, and the clamping block 62 in the push shell 61 drives the universal clamp 7 to contact with the additive material. After the universal clamp 7 contacts with the additive material, the clamping block 62 will slide in the push shell 61 driven by the push shell 61, and at this time the push shell 61 will continue to move in the direction of the additive material, thereby driving the embedded plate 75 to be inserted into the bottom of the additive material, so that the additive material is separated from the cradle turntable 8, and the clamping limit is realized during the additive manufacturing process, and the separation of the bottom of the additive material and the cradle turntable 8 is realized, so that the subsequent operator can take the additive material.

9. A method for using a dual-cladding head laser cladding metal additive manufacturing device, comprising the following steps: S1: When additive manufacturing is performed, two laser cladding heads (33) arranged on a screw slide (32) are used to perform additive manufacturing on a cradle turntable (8), the arranged lateral electric slide (2) can control the lateral movement of the laser cladding head (33), and the arranged screw slide (32) can adjust the height of the laser cladding head (33) to achieve additive manufacturing processing; S2: After the dual laser cladding device (3) realizes the processing and manufacturing of the additive material, the screw slide (32) drives the dual laser cladding device (3) to rise, and when it reaches the set height, the transmission telescopic plate (43) connected to the screw slide (32) will contact the wedge plate (44) set on the support seat (41), and at this time, the wedge plate (44) will move on the support seat (41), and when the opening (441) on the wedge plate (44) contacts the transmission rack (46), the transmission rack (46) is Driven by the elastic spring (47), it will move upward, and the movement of the transmission rack (46) will drive the rotating gear (48) to rotate, and the rotating gear (48) will rotate and contact with the moving rack (49), thereby driving the moving rack (49) to move. Through this arrangement, the dual laser cladding device (3) can contact with the transmission device (4) after the additive manufacturing is completed, and further through this arrangement, the additive material can be quickly clamped and limited after the additive manufacturing, so as to achieve the clamping and unloading of the additive material and improve the efficiency of the additive manufacturing; S3: When the movable rack (49) moves downward, it drives the push frame (53) to move downward, and the push frame (53) moves downward to contact the movable groove (521) on the push block (52), thereby causing the push block (52) to move on the fixed seat (51) in the direction of adding material. At this time, the push block (52) pushes the clamping member (6) in the direction of adding material, thereby realizing the clamping operation of adding material; S4: When the push block (52) drives the push sleeve (61) to move, the push sleeve (61) moves in the direction of the material addition, and the clamping block (62) in the push sleeve (61) drives the universal clamp (7) to contact the material addition. After the universal clamp (7) contacts the material addition, the clamping block (62) slides in the push sleeve (61) under the drive of the push sleeve (61), and at this time, the push sleeve (61) continues to move in the direction of the material addition. The insert plate (75) is moved, thereby driving the insert plate (75) to be inserted into the bottom of the additive material, so that the additive material is separated from the cradle turntable (8), and the clamping and limiting of the additive material during the additive material manufacturing process is realized, while the bottom of the additive material and the cradle turntable (8) are separated, so that it is convenient for subsequent operators to take out the additive material. The pressure spring (67) on the inner shell (63) is arranged so that the universal clamp (7) on the clamping block (62) can be moved only after the universal clamp (7) on the clamping block (62) contacts the additive material; S5: When the universal clamp (7) contacts the additive material, the positioning frame (74) contacts the outer wall of the additive material, and then the semi-arc chuck (73) and the semi-arc holder (72) will adaptively adjust according to the shape of the additive material, thereby preventing damage to the additive material during the clamping process.
