Fig. 1 to Fig. 6 is please referred to, production, operating process and the work of covering for roofs flexible welding tooling entirety of the invention are former
Reason is:
1, each section separated structure of each tooling unit 100 is prepared respectively, is fixedly connected by the state of Fig. 2,
Two tooling units 100 are symmetrically arranged, and fall in the distance of the two greatly according to the width dimensions of covering for roofs to be welded
In the adjustable range of cause；The driving parts such as all motors, cylinder are all connected to a control terminal, work is uniformly controlled by control terminal
It is dynamic.
2, make 22 actuation of the first driving driving section according to the width dimensions of covering for roofs to be welded first, adjust two works
The distance between the transverse shifting portion 23 of dress unit 100 reaches required precision.
3,32 actuation of driving section is driven in control second, rotates rotation axis 33, makes third fixed part 41 (longitudinal slide rail)
Angle reach required precision；
4, it (avoids welding after adjusting the suitable position that mobile fixing clamp 42 is on longitudinal slide rail (third fixed part 41)
Point), clip slot is opened, side stringer 201 is put into, control rotating down pressing cylinder 425, laterally and tightly propped cylinder 426 and end hold out against gas
427 three's actuation of cylinder forms opposite side stringer 201 and is positioned from tri- dimensions of X, Y, Z.In this way, arc bar 202 can be welded
It is welded on arc bar 202 on side stringer 201, then by straight-bar 203.
As previously mentioned, covering for roofs flexible welding tooling of the invention, the tooling unit being arranged symmetrically by two is formed, any
Distance regulating mechanism, angle adjusting mechanism and side stringer clamping positioning mechanism, Ji Ketong are equipped on the pedestal of tooling unit
The spacing that distance regulating mechanism comes between the pedestal of two tooling units of adjust automatically is crossed, it can also be automatic by angle adjusting mechanism
Adjust the soldering angle of side stringer, moreover it is possible to by side stringer clamping positioning mechanism come the position of adjust automatically gripper edge stringer, with
And automatically control the movement for clamping and loosening.So that entire welding tooling is able to achieve the regulatory function of multidimensional, not only greatly reduces
Manually-operated difficulty, improves efficiency, it is most important that welding tooling is made to adapt to the welding of the covering for roofs of various models.
Although specific embodiments of the present invention have been described above, those familiar with the art should be managed
Solution, we are merely exemplary described specific embodiment, rather than for the restriction to the scope of the present invention, it is familiar with this
The technical staff in field should be covered of the invention according to modification and variation equivalent made by spirit of the invention
In scope of the claimed protection.
