The set screw set on hole link 204, can realize carrying out coarse adjustment on focal length to microoptic head 205, in left and right
Focused on direction and in the longitudinal direction.
XY through holes link 204 is have mutually perpendicular two circles in X-direction (transverse direction) and in Y direction (longitudinal direction)
The link of through hole, the internal diameter of orthogonal two round tube holes respectively with the cylinder of bracket upright post 202 and rack cross-bar 203 outside
Footpath is adapted.For convenience with the connection of bracket upright post 202 and rack cross-bar 203, can be respectively on two inwalls of round tube hole
Copper sheathing with opening is installed, there is the set screw for tightening copper sheathing on two tube walls of round tube hole link.
The present invention is arranged on microoptic support 200 in the preceding outside of automatic spot head, with microoptic support
200 and the integrally mounted advantage of two independent structures of automatic spot head；Secondly as bracket upright post 202 and support are horizontal
Bar 203 is connected with two through holes of XY through holes link 204 respectively, and two through holes on XY through holes link 204 are erected with branch
The cylinder of post 202 and rack cross-bar 203 is the structure of adaptation, therefore, as long as regulation XY through holes link 204 and bracket upright post
202 set screw, microoptic head can be realized carrying out coarse adjustment on focal length and in left and right directions by bracket upright post 202
On focused；As long as the set screw of regulation XY through holes link 204 and rack cross-bar 203, microoptic head can be logical
Rack cross-bar 203 is crossed to be focused in the longitudinal direction, therefore, microoptic support 200 is arranged on automatic spot by the present invention
The preceding outside of head, can meet the use requirement that microoptic head works in spot welding completely.
Finally illustrate, electric resistance welding of the present invention under water it is micro- welding automation equipment the course of work：
When application electric resistance welding, micro- welding automation equipment exists to the enamel-covered wire lead-out wire of the small coil electronics of band under water
When substrate pad is welded, multiple even dozens of structures are identical, arrangement identical electronic component is positioned in workpiece water tank
On 107 workseat 112, water or emulsion or saponification liquor submergence electronic component are added in workpiece water tank 107, by PLC certainly
The stroke of dynamic control device control X-axis, Y-axis and Z axis, realizes moveable automatic in X-axis slide unit 105 and/or Y-axis slide unit 104
The movement of spot welding head 102, is added by the parallel electrode welding head 110 installed in automatic spot head 102 to welded piece 111
