[0004] During use, it was found that the above-mentioned device could not adjust the angle of the workpiece, resulting in a limited welding angle for the welding robot. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a welding robot for irregularly shaped space frames that reduces welding blind spots and improves welding efficiency.

[0006] This utility model discloses a welding robot for irregularly shaped space frames, comprising a base plate, a mounting base, a welding robot body, and a controller. The mounting base is located at the top of the base plate, and the welding robot body is located at the top of the mounting base. The controller is mounted on the top of the base plate and electrically connected to the welding robot body. It also includes a support assembly and a locking assembly. The support assembly is mounted on the top of the base plate and is used to place the workpiece. Multiple sets of locking assemblies fix the workpiece to the support assembly. The support assembly allows for horizontal and vertical angle adjustment of the workpiece. In use, the irregularly shaped space frame to be welded is placed on the support assembly and fixed by the locking assemblies. According to welding requirements, the operator uses the controller to operate the support assembly to adjust the horizontal and vertical angles of the irregularly shaped space frame. Then, according to a set program, the controller operates the welding robot body on the mounting base to weld the irregularly shaped space frame on the support assembly, reducing welding blind spots and improving welding efficiency.

[0007] Preferably, the support assembly includes an electric turntable, a vertical plate, a first pivot pin, a support platform, a second pivot pin, a servo electric cylinder, a third pivot pin, and positioning ports. The electric turntable is mounted on the top of the base plate, and the vertical plate is mounted on the top of the electric turntable. The top of the vertical plate is hinged to the bottom of the support platform with the cooperation of the first pivot pin. The bottom of the servo electric cylinder is hinged to the top of the electric turntable via the second pivot pin, and the top of the servo electric cylinder is hinged to the bottom of the support platform via the third pivot pin. Multiple sets of rectangular positioning ports are provided on the support platform. The irregularly shaped space frame is placed on top of the support platform. Afterwards, a set of locking components cooperates with a set of positioning ports to fix the irregular space frame. Then, according to the horizontal processing angle, the operator operates the electric turntable to rotate through the controller, so that the upright plate drives the support platform and the irregular space frame to adjust the horizontal angle through the first shaft pin. Then, the operator adjusts the length of the servo electric cylinder through the controller, so that the servo electric cylinder adjusts the vertical angle of the support platform with the cooperation of the second shaft pin, the third shaft pin and the first shaft pin, further adjusting the vertical angle of the irregular space frame and reducing the welding blind zone.

[0008] Preferably, the locking assembly includes a round rod, a rectangular clamping plate, a support plate, a square frame, a movable block, a lead screw, a handwheel, and a top fixing plate. The round rod has a rectangular clamping plate at its bottom end and a square frame rotatably mounted at its top end. A support plate slides within the square frame, and the support plate has a strip-shaped slot. The movable block slides within the strip-shaped slot. The movable block is I-shaped and has a threaded hole. The lead screw is threadedly connected to the threaded hole. A handwheel is mounted at the top end of the lead screw, and a top fixing plate rotatably mounted at its bottom end. The rectangular clamping plate is adapted to the positioning port. The rectangular clamping plate is inserted and passes through the positioning port. When the top end of the rectangular clamping plate is flush with the bottom end of the support platform, the round rod drives the rectangular clamping plate to rotate 90 degrees. Then, based on the position of the irregularly shaped space frame, the direction of the support plate is adjusted via the square frame. Next, the position of the movable block in the strip-shaped slot is adjusted. Finally, the handwheel rotates the lead screw, causing the lead screw to drive the top fixing plate to secure the top of the irregularly shaped space frame. The operator can adjust the position of the support plate within the square frame as needed, improving flexibility.

[0009] Preferably, it also includes a chamfered portion, with a chamfered portion provided at the bottom of the rectangular card plate; with the guidance of the chamfered portion, the worker can quickly insert the rectangular card plate into the positioning port, improving the ease of installation.

[0010] Preferably, the device also includes adjustable feet, with a set of adjustable feet provided at each of the four corners of the bottom of the base plate; when the ground surface is uneven, the operator can adjust the length of the adjustable feet, and the four sets of adjustable feet work together to provide stable support for the equipment and improve its stability.

[0011] Preferably, it also includes an anti-slip pad, and the bottom end of the lead screw is provided with an anti-slip pad; when the operator turns the handwheel, the lead screw drives the top fixing plate and the anti-slip pad to move downwards. With the cooperation of the anti-slip pad, the top fixing plate fixes the top of the irregular space frame, thereby avoiding hard wear between the top fixing plate and the irregular space frame and improving the fixing firmness.

[0012] Preferably, the frame also includes a wing bolt, and the frame is threadedly connected to the wing bolt. After the support plate is adjusted in position inside the frame, the operator rotates the wing bolt so that one end of the wing bolt is pressed against the outer wall of the support plate and fixed, thereby locking the position of the frame and the support plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: When in use, the irregular-shaped mesh frame to be welded is placed on the support component and fixed by the locking component. According to the welding requirements, the operator uses the controller to operate the support component to adjust the horizontal and vertical angles of the irregular-shaped mesh frame. Then, according to the set program, the controller operates the welding robot body on the mounting base to weld the irregular-shaped mesh frame on the support component, which reduces the welding blind zone and improves the welding efficiency.
