[0003] The above patent has the following problems: The pipe pile end plate itself is a mature product sold and circulated in the market. Its production and manufacturing itself belong to machining, and both the entry threshold and product added value are not high. Although the above patent can achieve the functions of automatic feeding, loading, and welding, its equipment structure is complex and numerous, and the number of robots reaches five, resulting in high manufacturing costs, procurement costs, and operation costs. Content of the Utility Model

[0004] The purpose of the utility model is to provide a welding device for pipe pile end plates, which has the effects of simple structure, convenient and fast use, and low cost.

[0005] The above technical purpose of the utility model is achieved through the following technical solutions: A welding device for pipe pile end plates includes a frame, a welding robot, and a vision system. A lifting seat is arranged on the frame, a lifting driving part for driving the lifting of the lifting seat, a pressing pipe rotatably connected to the lifting seat, and a rotating driving part for driving the rotation of the pressing pipe. A supporting bracket is arranged below the pressing pipe, and the supporting bracket is provided with a plurality of rotatable supporting shafts.

[0006] By adopting the above technical solution, the workpiece to be welded is placed on the supporting shaft, the lifting driving member drives the lifting seat to descend, so that the pressure tube is preliminarily pressed against the inner wall of the workpiece, the rotating driving member drives the pressure tube to rotate, and the vision system is used to collect images to identify the position of the gap to be welded. When the gap of the workpiece is located at the preset position, the rotating driving member stops driving the pressure tube to rotate, and the lifting driving member drives the lifting seat to descend further. The pressure tube on the lifting seat further presses and fixes the workpiece. The welding robot starts to weld the workpiece. Since the position of the gap to be welded on the workpiece is at the preset position, the welding movement path on the welding robot can be a straight line, and there is no need to configure a welding robot with a high degree of freedom, so as to reduce the equipment manufacturing cost on the premise of completing the welding operation.

The piston rod of the first oil cylinder is hinged to the swing arm. The upper end of the pressure arm is hinged to the middle of the swing arm, and the lower end of the pressure arm is hinged to the lifting seat.

[0008] By adopting the above technical solution, the piston rod of the first oil cylinder rises and falls, driving the swing arm to swing. The pressure arm on the swing arm drives the lifting seat to move, so as to drive the lifting seat to rise and fall.

[0009] A further setting of the present utility model is that: the rotating driving member includes a motor installed on the frame, a first transmission shaft, a second transmission shaft, and a third transmission shaft rotatably connected to the frame. The first transmission shaft is fixed to the output shaft of the motor. The second transmission shaft is universally connected to the first transmission shaft. One end of the third transmission shaft is universally connected to the second transmission shaft, and the other end is universally connected to the pressure tube.

[0010] By adopting the above technical solution, the motor drives the first transmission shaft to rotate, sequentially driving the second transmission shaft, the third transmission shaft, and the pressure tube to rotate. In this way, the pressure tube does not need to drive the whole motor to rise and fall while lifting, and is more flexible during the process of adjusting the lifting of the pressure tube, reducing the load of the first oil cylinder.

[0011] A further setting of the present utility model is that: a plurality of annular ridges are provided on the outer wall of the pressure tube.

[0012] A further setting of the present utility model is that: the frame is provided with a feeding rack, the feeding rack is slidably connected to the frame, and the feeding rack includes a front blocking rack, a rear blocking rack, and a connecting seat. The front blocking rack and the rear blocking rack are both fixed to the connecting seat.

[0013] By adopting the above technical solution, the workpiece is placed between the front blocking rack and the rear blocking rack and is supported by the supporting shaft. Moving the feeding rack can drive the workpiece to move, realizing feeding.

[0014] The utility model is further configured as follows: a guide rail is arranged on the frame, the length direction of the guide rail is consistent with the length direction of the pressure tube, a slider is fixed to the connecting seat, and the slider is slidably connected to the guide rail.

[0015] The utility model is further configured as follows: the number of the guide rails is two, and the number of the connecting seats is two.

[0016] The utility model is further configured as follows: the front baffle frame is provided with a clearance hole for the pressure pipe to pass through.

[0018] The utility model is further configured as follows: a second oil cylinder is fixed to the frame, and a piston rod of the second oil cylinder is fixed to the rear baffle frame.

[0019] By adopting the above technical solution, the second oil cylinder drives the rear baffle frame to move, thereby driving the feeding frame to move as a whole and realizing feeding.

[0020] The beneficial effects of the utility model are as follows: the utility model adjusts the lifting seat and the lifting and lowering of the pressure pipe through the lifting drive member, the pressure pipe is pressed on the inner wall of the pipe pile end plate after the initial descent, the rotating drive member drives the pressure pipe to rotate, driving the gap to be welded on the pipe pile end plate to move to a preset position, the rotating drive member stops driving the pressure pipe to rotate, the lifting drive member drives the lifting seat to further descend, and the pressure pipe on the lifting seat further presses and fixes the workpiece.
