Moreover, the existing welding machines and welding torches are immobile, resulting in insufficient convenience. Utility Model Content

[0003] Technical problem to be solved by the utility model

[0004] The technical problem to be solved by this utility model is to provide a robotic mobile welding device, which has the advantages of high efficiency, continuity, high quality, precise automated control, and convenient operation.

[0005] Technical solution

[0006] To solve the above problems, the technical solution provided by this utility model is as follows:

[0007] A robotic mobile welding device includes a support frame with casters at the bottom. The support frame is equipped with a clamping and positioning frame, a welding machine position, and a robot desktop. A collaborative robot is mounted on the robot desktop. The clamping and positioning frame is equipped with a clamping and positioning mechanism, which includes a base and a top seat. A cross connector is telescopically connected between the base and the top seat. A clamping connector is connected to the top seat and clamps the workpiece to be welded.

[0008] The support frame, serving as the foundation of the entire device, provides robust support. Casters located at the bottom of the frame grant the device excellent mobility and flexibility, enabling it to adapt to different production environments and operational needs. A clamping and positioning frame, situated on the frame, is used to fix the position of the workpiece to be welded, ensuring accuracy and stability during the welding process. A dedicated welding machine position is provided on the frame, ensuring a rational layout and ease of use. The robot desktop, located on the frame, provides a platform for the collaborative robot's operation. The collaborative robot, mounted on the robot desktop, performs precise welding tasks, and through programming, complex welding paths and high-precision control can be achieved. The clamping and positioning mechanism includes a base, a top mount, cross connectors, and clamping connectors. The base and top mount are connected by telescopic cross connectors, which can be adjusted according to workpieces of different sizes; the clamping connectors on the top mount are used to fix the workpiece to be welded, ensuring the stability of the workpiece's position during welding.

[0009] Optionally, the clamping and positioning mechanism further includes a handwheel. The end of the base is provided with a side plate. One side plate is hinged to the cross connector, and the other side plate is provided with a threaded hole and is connected to the rotating shaft of the handwheel. The other end of the rotating shaft is rotatably connected to a bottom moving block. The bottom moving block is slidably connected to the base. The base is provided with a bottom slide rail that slidably engages with the bottom moving block. The bottom moving block is hinged to the cross connector. The structure of the top seat is symmetrical to the structure of the base.

[0010] The handwheel drives the bottom moving block via its axle. This bottom moving block is slidably connected inside the base and cooperates with the bottom slide rail on the base to achieve linear reciprocating motion. The other end of the bottom moving block is hinged to the cross connector, so that when the handwheel rotates, the bottom moving block drives the cross connector to unfold or retract, thereby adjusting the clamping height. A top seat is symmetrically arranged with the base structure, and its structure is the same as the base, allowing for synchronous adjustment to adapt to different heights.

[0011] Optionally, a locking block is clamped to the outside of the handwheel's rotating shaft. The locking block is connected to the locking handle. The locking block includes a fixed block and a movable block. The fixed block and the movable block are passed through by the shaft of the locking handle. The locking handle is threaded to the movable block, and the fixed block is fixed to the side plate.

[0012] To achieve a stable locking function after height adjustment, a locking block is provided on the shaft of the handwheel. This locking block is linked to the locking handle and is used to mechanically fix the cross-connector after height adjustment, preventing displacement during welding. The locking block consists of two parts: a fixed block and a moving block. The fixed block is fixedly connected to the side plate of the base, serving as the basic support for the entire locking structure. The moving block is located on one side of the fixed block and forms a sliding or pressing fit with it. The shaft of the locking handle passes through the fixed block and the moving block in sequence, keeping them coaxially linked. The locking handle is threaded to the moving block. When the locking handle is rotated, the moving block is pushed towards the fixed block through the threaded transmission, thereby clamping the shaft or connecting component in the stroke and locking the adjustment position. When the clamping height needs to be adjusted, the locking handle is rotated in the opposite direction to move the moving block away from the fixed block, releasing the clamping state. At this time, the handwheel can be rotated freely to drive the bottom moving block to slide along the bottom slide rail, thereby driving the cross-connector to unfold or retract, realizing the adjustment of the clamping height.

[0013] Optionally, the top seat is connected to the clamping connector via a steering clamp. The side wall of the steering clamp is a deformable structure. A clamping screw is connected between the side walls of the clamp. One end of the clamping screw is axially limited to one side wall of the clamp and fixedly connected to a clamping handle. The other end of the clamping screw is threaded to the other side wall of the clamp. A clamping shaft is slidably connected to the side wall of the clamp and is rotatably connected to the clamping connector via the clamping shaft.

[0014] To achieve more flexible and adaptable clamping and positioning of the welded workpiece, a swivel clamp is connected to the clamping connector via a swivel clamp on the top seat. This swivel clamp has a certain degree of rotational freedom and can adjust its posture according to the actual position and angle of the welded workpiece, thereby improving the adaptability and stability of the clamping. The steering clamp includes a pair of opposing clamp sidewalls, which are deformable structures with a certain degree of elasticity and deformation capacity, facilitating buffering and fit during clamping. A clamping screw is provided between the two clamp sidewalls for adjusting the clamping angle and achieving a locking function. One end of the clamping screw is axially limited to one side clamp sidewall and is fixedly connected to a clamping handle, allowing the operator to manually rotate it to control the clamping state. The other end of the clamping screw is threaded to the other side clamp sidewall. Rotating the clamping handle drives the clamping screw to rotate, thereby pushing the clamp sidewalls closer or further apart, achieving adjustment and fixation of the clamping angle. A clamping shaft is also provided between the clamp sidewalls, with both ends slidably connected to guide grooves or sliding holes on the clamp sidewalls, allowing the clamping connector to deflect within a certain range of angles relative to the clamp via the shaft. The clamping connector forms a rotatable connection with the steering clamp through the clamping shaft, allowing it to freely adjust its angle when the clamping screw is not fully locked, and maintaining a fixed posture after locking.

[0015] Optionally, the handwheel is provided with anti-slip texture.

[0016] The outer edge of the handwheel has evenly distributed anti-slip textures, which increases the friction between the hand and the handwheel contact surface, effectively preventing slippage even when the operator is wearing gloves or has sweaty hands.

[0017] Optionally, the clamping connector is equipped with clamping claws by bolts and screws, and the clamping claws hold the welding workpiece.

[0018] The clamping connector, a key component connecting the steering chuck and the gripper, provides a stable support base and forms a rotatable connection with the steering chuck through threaded holes or other fixing structures. The gripper, the part that directly contacts the workpiece being welded, is typically made of high-strength, wear-resistant materials to ensure it is not easily damaged during clamping and can provide sufficient clamping force. The gripper is securely attached to the clamping connector using bolts and screws.

[0019] Optionally, the collaborative robot has a multi-axis structure and is connected to the welding machine, and a push-pull wire welding gun is connected to the end of the collaborative robot.

[0020] The collaborative robot features a multi-axis structure and is connected to a welding machine, with a push-pull wire welding gun attached to its end. This design not only improves flexibility and precision during the welding process but also enhances operational safety and convenience.

[0021] Optionally, the welding machine position is provided with a positioning angle plate, which cooperates with the welding machine.

[0022] The positioning angle plate is specifically designed for use with welding machines, enabling quick and accurate installation and fixation of the welding machine, thereby improving the stability and efficiency of the entire welding system.

[0024] Compared with the prior art, the technical solution provided by this utility model has the following advantages:

[0026] High efficiency and continuity: Improve work efficiency and reduce downtime through automated control;
