Piston bar pushes base 411, and it is with by the connecting pin number of weldering commutator consistent to push radix mesh, respectively pushes base along band rotating ring week
To being uniformly distributed.The base that pushes is with top surface 4111, two guiding surfaces 4112 on an arc, guiding surface and with rotating ring
Top surface is tack welding socket part away from ring axis are driven apart from maximum on diameter parallel, arc.The mainframe is provided with support base
451, support spring axis vertical, support spring lower end is fixed with support base, and support spring upper end is fixed with Mobile base bottom.
In this programme, hydraulic oil only in active oil pocket, oil pipe, lower pumping cavity flow, namely active oil pocket, oil pipe, under
Filled with hydraulic oil in pumping cavity, active cavity, push in cavity do not have hydraulic oil (active cavity, push cavity with air connect
Logical, this is the prior art in oil cylinder field, otherwise can influence the normal work of oil cylinder).Rotary electric machine drives commutator to rotate and set
Determine angle (360 degree divided by connecting pin number), allow a connecting pin of commutator to go to below plumb joint, at the same time, turning
During dynamic, band rotating ring is also rotated together with commutator, scroll chuck, when pushing base and starting to go to contact active piston bar,
It can push and push piston rod and move up, a part of hydraulic oil in active oil pocket begins to pass through oil pipe into lower pumping cavity, under drive
Pressure piston rod pushes down on Mobile base, so as to drive welding machine (plumb joint) to move down, weld part to be positioned, which is touched, pushes piston rod
During lower end, now plumb joint is depressed into lower limit position, and rotary electric machine can suspend, after the completion of welding, then rotates electricity
Machine is rotated further, and commutator continues to rotate, and is pushed base and is left and pushes piston rod, and under action of reset spring, active piston bar is answered
Position, drive pushes piston rod reset, and acting on lower mobile base, welding machine in support spring also resets, and so just completes a connection
The welding of pin, subsequent rotary electric machine continues to rotate, and repeats above-mentioned action, can carry out the welding of next connecting pin.And it is each
Rotary electric machine suspends, when being also that plumb joint is pushed in place just, can ensure welding all accurate positionings, welding position every time
Deviation is minimum, can effectively ensure that welding quality.And by the linkage of a whole set of mechanism, realize plumb joint and push and commutator turn
Dynamic automatic cooperation positioning, has ensured the accuracy of each welding position, and due to being machinery positioning, precision fully relies on structure
Itself realize, can avoid calculating the error caused by control (circuit module control).In addition, turn positioning screw, makes positioning
Screw is left after Mobile base, and the position of adjustable plumb joint (allow fuselage to be slided on Mobile base, after slip in place, turn again
Positioning screw, makes positioning screw compress mobile seating face again, so that it may realize the reposition of placement plate and fuselage), make weldering
Joint location adapts to the connection placement of foot of different commutators, so as to be welded to a variety of commutators.
The mainframe is provided with least one guide rod 46, and guide rod is vertical and is fixed with mainframe, is set on Mobile base
There is slide opening, guide rod external diameter is adapted to slide opening internal diameter, guide rod is slidably matched through slide opening and slide opening.Set on guide rod
Limited location block 461, limited block is in above Mobile base.Guide rod can aid in Mobile base to move up and down, and improve Mobile base
The stability of the course of work.When Mobile base resets, limited block can limit the ultimate range of Mobile base rising, it is to avoid be moved through
Degree.
Also including an auxiliary sizing strip 51 for depressing commutator connecting pin, auxiliary sizing strip is connected by sizing strip frame 52
It is connected on plumb joint.The sizing strip frame includes heat conduction sliding sleeve 521, some heat conduction connecting rods 522, and auxiliary sizing strip is slided with heat conduction
Set is slidably connected, and the slidably direction of auxiliary sizing strip is the self-regulation bullet that axis vertical is provided with above-below direction, heat conduction sliding sleeve
Spring 523, self-regulation spring upper end connection heat conduction sliding sleeve, self-regulation lower spring end connection auxiliary sizing strip upper end aids in sizing strip
Lower end is stretched out outside heat conduction sliding sleeve, and heat conduction connecting rod one end is connected with plumb joint, and the heat conduction connecting rod other end is connected with heat conduction sliding sleeve,
The residing height in sizing strip lower end is aided in less than the residing height in plumb joint lower end.During welding, Mobile base drive welding machine move down, before
Through mentioning, the plumb joint of welding machine will also melt away on lead-out wire (with commutator connecting pin junction) in addition to welding to be completed
Paint film, still, in actual production, for safeguard work efficiency, welding time of contact can not possibly be very long every time, and under plumb joint
Relative end size is also fixed, it is possible to cause paint film to eliminate not enough, influences conductive effect, and being pressed downward for connecting pin
It is dynamic to be also completely dependent on plumb joint, it is short due to pressing the time, it is impossible to ensure the journey that connecting pin is further deformed and (inwardly compressed) very well
Degree.And in this programme, the heat on the plumb joint of high temperature through heat conduction sliding sleeve can be transmitted to auxiliary sizing strip by heat conduction connecting rod
On, in plumb joint folding process, auxiliary sizing strip touches commutator connecting pin and enamel-covered wire (lead-out wire) one step ahead, from
And can heat in advance, melt away paint film, and aid in connecting pin is pushed, subsequent plumb joint complete again welding (auxiliary calmly
Type bar is touched after connecting pin, is just pressed in always on connecting pin, and is stepped into heat conduction sliding sleeve, until welding terminates, it is mobile
After seat lifts, just can gradually be resetted under self-regulation spring effect), equivalent on the premise of work rhythm is constant, additionally prolong
Grow and melted paint, weld interval, can effectively lift welding quality, optimized product quality.
Any point is equal with the minimum range between rotating ring outer ring surface on top surface on the arc.On arc on top surface
Any point is equal with the minimum range between rotating ring outer ring surface, it is meant that as long as top surface heads on active piston bar on arc,
So the position of active piston bar is just constant, until top surface leaves active piston bar on arc, starts by guiding surface or band
When rotating ring outer ring surface contacts active piston bar, the relative altitude of active piston bar can just decline.So rotary electric machine is just ensured
Can continuously it rotate, after top surface jack-up active piston bar on the arc with certain length, top surface does not leave master on arc
In that time of piston bar, plumb joint can persistently be pressed in weld, and the paint film for carrying out lead-out wire weld is eliminated, persistently entered
Being welded to connect for row lead-out wire and connecting pin, so that rotary electric machine is without repeatedly starting and stopping, can effectively lift continuity, further subtract
Few position error.
