[0022] Working principle: When the automobile welding manipulator with positioning function is used, the motor 1 2 is started to rotate the rotating rod 3 to make the sliding block 5 slide on the surface of the base 1, and the limit block 4 is set to offset during the rotation of the rotating rod 3. When the sliding block 5 slides to the specified position, the motor 2 7 is started to drive the threaded rod 8 to rotate. Since the connecting block 9 is threadedly connected to the threaded rod 8, when the threaded rod 8 rotates, it will drive the connecting block 9 to move upward, and then drive the fixed plate 10 fixedly connected to one side of the connecting block 9 to rise. Since the surface of the fixed plate 10 is fixedly connected with a friction nut The friction plate 12 is fixedly connected to the lower end of the sliding block 5. When the fixed plate 10 rises, the friction plate 11 and the friction plate 12 are pressed together, and then the sliding block 5 is fixed. During the operation of the manipulator, the rotating column 16 needs to be rotated to achieve welding of components in different directions. When the rotating column 16 rotates to a specified position, the sensor 13 receives a signal from the signal transmitter 18, and then the telescopic rod 20 inside the fixed block 19 fixedly connected to one side of the sliding block 5 is started. As the telescopic rod 20 contracts, the connecting plate 2 1 moves downward, so that the fixed slider 22 is inserted into the gap between the tooth blocks 17, so as to fix the rotating column 16. When the fixed slider 22 moves downward and contacts the tooth blocks 17, the gap between the fixed slider 22 and the tooth blocks 17 may not be aligned. At this time, the fixed slider 22 is fine-tuned through the arc-shaped slide groove opened on the lower surface of the connecting plate 21, so that the fixed slider 22 can fix the rotating column 16 more quickly. When the rotating column 16 is fixed, the force arm group 23 drives the welding head 26 to move to the specified position through the control program, and then the welding work is carried out. During welding, the air pump 32 is started, and the suction force generated will absorb the metal debris generated by welding. The metal debris enters the collecting bin 27 through the connecting pipe 28. Due to the existence of the filter plate 30, the metal debris falls into the collecting bin 27 for collection when the air pump 32 stops running. The collecting bin 27 can be cleaned regularly. When the rotating block 25 drives the welding head 26 to rotate to weld at different positions, due to the existence of the connecting hose 31, the suction force of the air pump 32 is prevented from being unable to absorb the metal debris.
[0023] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
