Technical Field
[0001] This utility model relates to the technical field of welding equipment, and in particular to a hollow rotor welding equipment. Background Technology
[0002] To ensure the normal operation of the pump and prevent media leakage, the hollow rotor of a screw pump is usually sealed at both ends.

The clamping and rotating assembly, the fixing assembly, the auxiliary rotating assembly, and the welding assembly are respectively located at the top of the worktable. In use, one end of the hollow rotor is fixed by the clamping and rotating assembly, and the sealing plate is aligned with the other end of the hollow rotor. The fixing assembly is operated to fix the center of the sealing plate. Then, the welding assembly is operated to weld the hollow rotor and the sealing plate. The clamping and rotating assembly is started, thereby causing the hollow rotor and the sealing plate to rotate, thereby causing the welding assembly to weld the hollow rotor and the sealing plate.
[0007] Preferably, the clamping and rotating assembly includes a first fixed plate, a chuck, and a first motor. The first fixed plate is provided at the top of the worktable, and the chuck and the first motor are provided on the first fixed plate. The first motor is used to rotate the chuck. One end of the hollow rotor is clamped by the chuck, and the first motor is started, so that the chuck drives the hollow rotor to rotate.

The sealing plate is aligned with the right end of the hollow rotor. The second hydraulic cylinder is extended, thereby causing the movable plate to drive the conical rod to move to the left. The conical rod contacts the center of the right end of the sealing plate, thereby fixing the sealing plate. After the welding assembly spot welds the hollow rotor and the sealing plate, the chuck drives the hollow rotor and the sealing plate to rotate synchronously, improving welding efficiency.
[0010] Preferably, the welding assembly includes a No. 3 hydraulic cylinder, a guide rod, a movable seat, a support frame, a No. 4 hydraulic cylinder, a mounting base, and a laser welding head. The top of the worktable has a groove, in which the No. 3 hydraulic cylinder and the guide rod are positioned.

A mounting base is located at the bottom movable end of the No. 4 hydraulic cylinder, and a laser welding head is located at the bottom of the mounting base. Based on the position of the contact area between the sealing plate and the hollow rotor, the position of the movable seat is adjusted using the No. 3 hydraulic cylinder, further adjusting the horizontal position of the laser welding head. The No. 4 hydraulic cylinder is then extended, causing the mounting base to lower the laser welding head, which then welds the hollow rotor and the sealing plate.
[0011] Preferably, the worktable also includes adjustable feet, with a set of adjustable feet provided at each of the four corners of the bottom of the worktable; the four sets of adjustable feet work together to provide stable support for the worktable and improve stability.
