The beneficial effects of the utility model are: welding arm is set to two-part structure, and second section arm There is the degree of freedom of horizontally and vertically both direction, in that context it may be convenient to entered by the particular location of welding gun head Row freely adjusts, and substantially increases work efficiency and operating accuracy.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

In figure, 1, base, 2, welding gun head, 3, first segment arm, 4, second section arm, 5, power-assisted Device, 6, protecting crust, 7, lifting hands.

Detailed description of the invention

This utility model is a kind of automatic welding mechanism, and welding arm is set to two-part structure, and the Two joint arms have the degree of freedom of horizontally and vertically both direction, in that context it may be convenient to concrete by welding gun head Position carries out free adjustment, substantially increases work efficiency and operating accuracy.

With specific embodiment, this utility model is described further below in conjunction with the accompanying drawings.

Specific embodiment, as it is shown in figure 1, a kind of automatic welding mechanism, including base 1, welding arm and Welding gun head 2, one end of welding arm is fixed on base 1, the welding arm other end and welding gun head 2 Fixing, the most adjustable in order to realize welding arm angle, welding arm is designed as the Split type structure of two-part, Including first segment arm 3 and second section arm 4, first segment arm 3 one end is hinged with base 1, first segment arm 3 The other end is hinged with one end of second section arm 4, and second section arm 4 other end is hinged with welding gun head 2, Second section arm 4 is parallelogram linkage, and first segment arm 3 sets with the junction of second section arm 4 Have horizontally and vertically two, a direction rotary freedom, the most in the horizontal direction can with angle-adjustable, Rotate from owing to the junction of second section arm 4 with welding gun head 2 also is provided with horizontally and vertically two, direction By spending, vertical direction can also arbitrarily carry out lifting operation, and the location making welding gun head 2 is more accurate, Improve welding precision.

In order to alleviate when workman adjusts welding gun head 2 angle firmly, second section arm 4 with weld rifle The junction of 2 is provided with power assisting device 5, preferably air spring as power assisting device 5, power assisting device The steering force of 5 is less than the gravity of welding gun head, and the such as gravity of welding gun head 2 is 40N, then power-assisted dress The steering force putting 5 offers is 35N, and such workman has only to the power of offer more than 5N can be to welding rifle 2 carry out lifting and stretch the operation dragged, and after welding gun head 2 arrives at above welding post, workman looses one's grip, Welding gun head 2 can be vertically lowered in the effect of gravity and be subjected to Welder face, reduces The labor intensity of workman, improves work efficiency and also improves welding precision, do not have due to welding gun Play motion the most smooth causing weld offending problem.

It is provided with to enable welding arm to have effect dust-proof and attractive in appearance, the also outside at welding arm Protecting crust 6, protecting crust 6 is installed on the outside of welding arm, and opening is left at the two ends of protecting crust 6, permissible Angle is adjusted for welding arm.

For convenience welding gun head 2 is carried out angle adjustment, the lateral wall of welding gun head 2 also sets Being equipped with lifting hands 7, workman only needs to lift to stretch by hand to drag and the angle of welding gun head 2 can be carried out random angle The adjustment of degree.

The bottom of base 1 is provided with discoidal fixed disk, fixed disk provided circumferentially about uniformly There is multiple fixed bolt hole, when fixing this utility model, use fixing bolt to be fixed on by base 1 Ground.

The length ratio of first segment arm 3 with second section arm 4 is designed as 1:(1-1.1), preferably 1:1 is Good, a length of 0.5m of such as first segment arm 3, second section arm 4 length is also 0.5m, so welds The total length of arm i.e. can reach 1m, different if as demand, needs various sizes of welding arm, presses Ratio expands or shrinks.

Welding arm is set to two-part structure by this utility model, and second section arm has horizontally and vertically The degree of freedom of both direction, in that context it may be convenient to the particular location of welding gun head is carried out free adjustment, greatly Improve greatly work efficiency and operating accuracy.
