During welding, the driving device 10 is matched to drive the U-shaped frame 1 so as to drive the welding gun 21 to move along a welding surface, and welding of a zigzag route is realized.
The angular adjustment of the welding gun assembly 2 is:
referring to fig. 11i and 11j, when the angle of the welding gun assembly 2 needs to be adjusted clockwise, the first motor 31 rotates anticlockwise, the adjusting gear 4 moves leftwards, and meanwhile, the adjusting gear 4 drives the driving frame 81 to move leftwards through the driving arm 82, the driving frame 81 moves to the lowest position of the inclined section 812 of the driving frame 81 from the middle horizontal section 811 of the driving frame 81 to the protruding shaft 72;
referring to fig. 11k and 11L, the first motor 31 continues to rotate anticlockwise, the adjusting gear 4 continues to move leftwards, and drives the frame 81 to move through the driving arm 82, the protruding shaft 72 slides upwards along the inclined section 812 of the driving frame 81, so that the driving frame 81 can drive the protruding shaft 72 to move upwards, the protruding shaft 72 drives the connecting shaft 71 to move upwards, the connecting shaft 71 drives the clamping block 73 to move upwards and move out of the clamping groove 63, when the clamping block 73 moves out of the clamping groove 63, the protruding shaft 72 moves to the uppermost side of the inclined section 812 of the driving frame 81, enters the horizontal sections 813 on both sides, and the left side of the adjusting gear 4 is attached to the right side of the first unidirectional gear 52;
referring to fig. 11m and 11n, the first motor 31 continues to rotate counterclockwise, the adjusting gear 4 continues to move to the left and rotate, when the teeth on the adjusting gear 4 correspond to the tooth grooves of the first unidirectional gear 52, the adjusting gear 4 can be directly meshed with the first unidirectional gear 52, when the teeth do not correspond to the tooth grooves, the adjusting gear 4 compresses the elastic member 43, and when the adjusting gear 4 rotates until the teeth correspond to the tooth grooves of the first unidirectional gear 52, the adjusting gear 4 is pushed to be meshed with the first unidirectional gear 52 by the action of the elastic member 43;
at this time, when the adjusting gear 4 rotates again, the rotating shaft 51 can be driven to rotate clockwise through the first unidirectional gear 52, and the rotating shaft 51 drives the welding gun assembly 2 to rotate through the second square shaft 54 at the end part and the sleeve 24, so that the counterclockwise rotation adjustment of the welding gun assembly 2 is realized.
After the adjustment is completed, the first motor 31 rotates clockwise to drive the adjusting gear 4 to move to the original position, wherein when the driving frame 81 moves back, the driving shaft 72 moves from top to bottom along the inclined section 812, so as to drive the clamping block 73 to be inserted into the corresponding clamping groove 63 to limit the clamping block.
Referring to fig. 12, when the angle of the welding gun assembly 2 needs to be adjusted clockwise, the principle is similar to that described above, and the output shaft of the first motor 31 can be rotated clockwise.
The foregoing description is only illustrative of the present invention and is not intended to limit the scope of the invention, and all equivalent structures or equivalent processes or direct or indirect application in other related technical fields are included in the scope of the present invention.
