The turning assembly 3c is connected to the lifting plate 3b2 through a rotating rod 3b3. The driving mechanism is connected to the lifting screw 3b1 in a transmission connection.

[0045] Specifically, in order to solve the technical problem that when welding the aluminum alloy door and window frames, the frame needs to be lifted up to a certain height and then flipped for reverse welding, the present invention drives the lifting component 3b to lift and lower the frame bar clamping component 4 and the length adjustment mechanism 5 through the driving component 3d, and the driving component 3d drives the lifting screw 3b1 to rotate, so that the lifting plate 3b2 moves vertically along the guide groove 3b4 on the flip frame 3a.

[0051] Specifically, in order to solve the technical problem of transmission of the flip assembly 3c and the lifting assembly 3b, the present invention drives the corresponding worm part 3d5 to rotate by driving the motor 3d1, and then drives the transmission rod 3d2 and the other worm part 3d5 to rotate.

[0060] Specifically, in order to solve the technical problem of clamping two connected frame strips, the present invention uses an angle clamp 4b and a clamping seat 4a to form a clamping groove with a specific angle. The angle formed by the two frame strips is determined by the shape of the angle clamp 4b. Different shapes of angle clamps 4b can be selected according to production requirements. The staff or the manipulator sequentially places each frame strip on two adjacent clamping seats 4a.

[0067] S5: When the welding of the upper side of the frame is completed, the driving component 3d drives the lifting component 3b to lift and lower the frame bar clamping component 4 and the length adjustment mechanism 5, and the driving component 3d drives the lifting screw 3b1 to rotate, so that the lifting plate 3b2 moves vertically along the guide groove 3b4 on the flip frame 3a.

A clamping head 7a and a clamping groove 8a are respectively provided at the splicing position of the long frame bars 7 and the short frame bars 8.

[0069] Specifically, in order to solve the technical problems that aluminum alloy doors and windows are easily misaligned during the splicing process, or the splicing parts are uneven during the welding process, resulting in frame deformity, the present invention provides an aluminum alloy door and window frame that can quickly realize frame strip splicing and is not easy to dislocate, and utilizes the clamping head 7a and the clamping groove 8a structure on the long frame strip 7 and the short frame strip 8 to achieve the splicing engagement and ensure that the frame will not be misaligned.

4. The aluminum alloy door and window automatic welding equipment according to claim 3 comprises an aluminum alloy door and window welding process, characterized in that: The steps include: S1: The length and width between the corresponding frame bar clamping components (4) are adjusted according to production requirements to form a specific door and window frame structure, and the corresponding adjustment seat (6a) is pushed to move on the guide slide rail (6d) by the second push rod (6e), and the transmission between the second sliding rack (6b) and the second rotating gear (6c) on the two adjustment seats (6a) is used to realize that the two adjustment slides can move toward each other synchronously to meet the adjustment of the frame width; S2: The first push rod (5h) pushes the two connecting blocks (5g) and the limit rod group (5f) to move toward each other, thereby driving the adjustment frame (5a) and the frame bar clamping assembly (4) to move, and the transmission between the connecting seat (5b) and the first sliding gear and the first rotating gear (5d) is used to achieve the synchronous movement of the frame bar clamping assemblies (4) at both ends toward each other, thereby achieving the length adjustment of the frame to meet the production requirements; S3: An operator or a manipulator places frame strips of corresponding sizes one by one between two corresponding frame strip clamping assemblies (4), and uses an angle clamp (4b) and a clamping seat (4a) to form a clamping groove of a specific angle. The angle formed by the two frame strips is determined by the shape of the angle clamp (4b). An angle clamp (4b) of different shapes can be selected according to production requirements. The operator or the manipulator places each frame strip on two adjacent clamping seats (4a) in sequence. The angle bracket and the sliding clamp (4c) press the frame strip against the clamping seat (4a) under the action of the spring (4d), thereby achieving fixed clamping of the frame. S4: The welding manipulator (1) welds the frame after the splicing and clamping is completed, and the turntable module (2a) of the welding platform (2) is used to realize the horizontal rotation of the frame, so that the welding manipulator (1) can weld other angles of the frame; S5: When the welding of the upper side of the frame is completed, the driving component (3d) drives the lifting component (3b) to lift and lower the frame bar clamping component (4) and the length adjustment mechanism (5), and the driving component (3d) drives the lifting screw (3b1) to rotate, so that the lifting plate (3b2) moves vertically along the guide groove (3b4) on the flip frame (3a). After moving to a certain height, the length adjustment mechanism (5) and the frame bar clamping component (4) are synchronously flipped under the action of the flip component (3c). After the flip is completed, the welding robot (1) continues to weld the other side of the frame.

5. The aluminum alloy door and window automated welding equipment according to claim 1, wherein the aluminum alloy door and window welded is characterized in that: The aluminum alloy door and window comprises two long frame bars (7) and two short frame bars (8); the long frame bars (7) and the short frame bars (8) are spliced ​​together to form a door and window frame; and a clamping head (7a) and a clamping groove (8a) are respectively provided at the splicing position of the long frame bars (7) and the short frame bars (8).
