referring to fig. 11k and 11L, the first motor 31 continues to rotate counterclockwise, the adjusting gear 4 continues to move to the left, and the driving arm 82 drives the frame 81 to move, the protruding shaft 72 slides upward along the inclined section 812 of the driving frame 81, so that the driving frame 81 can drive the protruding shaft 72 to move upward, the protruding shaft 72 drives the connecting shaft 71 to move upward, the connecting shaft 71 drives the clamping block 73 to move upward and move out of the clamping slot 63, when the clamping block 73 moves out of the clamping slot 63, the protruding shaft 72 moves to the uppermost side of the inclined section 812 of the driving frame 81 and 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 one-way gear 52;
referring to fig. 11 (m) and 11 (n), at this time, the first motor 31 continues to rotate counterclockwise, at this time, the adjusting gear 4 continues to move and rotate to the left, when the teeth on the adjusting gear 4 correspond to the tooth grooves of the first one-way gear 52, the adjusting gear 4 may be directly engaged with the first one-way gear 52, when not corresponding, the adjusting gear 4 first compresses the elastic member 43, and when the adjusting gear 4 rotates until the teeth of the adjusting gear 4 correspond to the tooth grooves of the first one-way gear 52, the adjusting gear 4 is pushed to be engaged with the first one-way gear 52 by the action of the elastic member 43;
at this time, when the adjusting gear 4 rotates again, the first one-way gear 52 can drive the rotating shaft 51 to rotate clockwise, and the rotating shaft 51 drives the welding gun assembly 2 to rotate through the second square shaft 54 at the end part in cooperation with the sleeve 24, so as to realize the counterclockwise rotation adjustment of the welding gun assembly 2.
After the adjustment is completed, the first motor 31 rotates clockwise to drive the adjusting gear 4 to move to the original position, and when the driving frame 81 moves back, the protruding shaft 72 is driven to move 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, and limit the clamping groove.
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 rotates clockwise.
The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes, which are made by using the contents of the present specification and the accompanying drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
