The equipment of end turn welding on stator
Technical field
The present invention relates to stator coil end welding technology field, particularly relate to a kind of end turn welding on stator
Equipment.
Background technology
The stator of three phase alternating current motor is by stator core and the three-phase windings coil structure being inlaid in this stator core slot wedge
Become.And after coil is fitted on slot wedge, it is scattered for some coil exposing stator end.And put at stator
Will be welded as a whole before use one soldering tip of formation by the wire harness of exposed portion on each coil, and this soldering tip must be correspondence
Every single line on coil all includes;Because, if the soldering tip solder skip single line on a coil, and do not have on other coils
There is solder skip phenomenon, then will result in the unbalanced phenomenon of three-phase electricity, i.e. three phase alternating current motor and can not realize normally working, from
And cause motor defective.In prior art, for the welding of end turn by manually welding, operator are hand-held
Wire harness, and wire harness is placed on below welding machine, carry out reciprocal rotational line bundle by hands, thus end turn is welded into a weldering
Head.And this welding method easily causes the phenomenon of solder skip, and operator in long-term welding process, labor intensity is the most very
High.
Summary of the invention
The technical problem to be solved in the present invention is, overcomes existing technological deficiency, it is provided that one can be avoided wire harness

End turn on stator of the present invention is coordinated by support bar and the second cylinder with fixed coil, and coil free end
Through the circular hole on rotating disk, and coil free end is clamped on circular hole internal perisporium by latch;Under the work of power set, turn
Dish has enough to meet the need relative to support bar, i.e. coil free end rotates relative to stator, such that it is able to twisted into by end turn
Flos Cannabis structure, so, it is possible to every line on coil is included in Flos Cannabis structure and suffers;Drive followed by the first cylinder
End turn on moving platform moves as reciprocating linear relative to welding machine, thus can be pointed to support bar by welding machine and be turned
End turn between dish is welded as a soldering tip with certain length, and this soldering tip contains each on a coil
Line;After a coil has welded, the second air cylinder driven pushing block disengages with groove, and one hands of operator can drive latch
Rise to order about latch bottom and the disengaging of coil free end, thus facilitate the switching of coil;Can by the setting of guider
To guarantee that platform moves back and forth accurately relative to workbench, so ensure coil when moving back and forth always situated in welding machine just
Lower section, and coil can be clamped in the groove on support bar by the cooperation of pushing block and the first breach, and pass through groove
Motion to pushing block provides guiding;Coil can be clamped on circular hole internal perisporium by the claw of latch bottom, and, the
Guide the coordinating can the motion of latch be provided of one plane and the second plane and square hole, prevent latch along rotating disk radially slide time
Occur sliding inclined;The setting of the first stage clip may insure that end turn due to after twisting into Flos Cannabis the volume latch that diminishes persistently clamp coil
Free end, i.e. latch can promote claw to clamp coil free end further under the elastic force effect of the first stage clip, so that it is guaranteed that
Coil free end is clamped in the circular hole of rotating disk all the time;By support means so that rotating disk keeps vertical state, i.e. turn
The axis of dish presents level;And rotating disk biography can be improved by support means with coordinating with annular protrusion while of power set
Dynamic accuracy, and the setting of depression bar may further ensure that rotating disk keeps vertical state, and, depression bar is also prevented from rotating disk
Depart from from support means;It addition, stator is contained in stopper slot, and by the cooperation of push rod and the second stage clip by stator pressure

Detailed description of the invention
The invention will be further described with detailed description of the invention below in conjunction with the accompanying drawings.
The operation principle of the present invention:
First, the hand-held handle of operator pulls push rod to move obliquely, is placed in stopper slot by stator, unclamps and push away
Bar, push rod is in the effect declivity slide downward of the second stage clip elastic force, until the boss top of push rod lower end is to stator left part, and
Till stator right part is against stopper slot end, state as shown in Figure 2;Then, the hand-held draw ring of operator drives on latch
Claw and circular-hole internal-wall depart from, then take on stator on groove that an overhang sequentially passes through on support bar, rotating disk
Circular hole, operator unclamp draw ring, and latch slides towards rotating disk axis direction under the elastic force effect of the first stage clip, i.e. claw clamping
On circular hole internal perisporium, thus complete the clamping to coil free end;And then, the second cylinder operation is propped up to be clamped in by coil
In groove on strut;
Then, motor task driven the second axis of rotation, the second rotating shaft drives external gear around turntable shaft by the second gear
Line rotates, say, that rotating disk there occurs rotation relative to support bar, i.e. the coil of right part is sent out relative to the coil of left part
Raw rotation, thus can twist into end turn twisted shape, and then be included in this twisted shape by every line on coil, anti-
Only wired disengaging from wire harness in follow-up welding process;
Then, welding machine works, and the first air cylinder driven platform moves back and forth relative to workbench, and platform is each time
In reciprocating movement, the twisted shape end turn that welding machine all can be pointed between support bar with rotating disk welds, thus will
