The automatic shearing mechanism of stator winder
Technical field
The utility model relates to the stator winder field, relates in particular to a kind of automatic shearing mechanism of stator winder.
Background technology
In the motor stator production process; The operation of winding winding need be used stator winding equipment usually on stator; The indexing mechanism that existing stator winding equipment generally only is equipped with coiling mould, winding mechanism and stator is installed; Need after stator winding finishes to be interrupted enamelled wire, increased production cost, reduced production efficiency through manual type.
The utility model content
The utility model embodiment technical problem to be solved is, a kind of automatic shearing mechanism of stator winder is provided, can automatic discontinuous enamelled wire after stator winding finishes, improved production efficiency, and reduced production cost.
In order to solve the problems of the technologies described above; The utility model embodiment has proposed a kind of automatic shearing mechanism of stator winder, comprising: the clamp cutter, the thread trimmer on the outer wall that axially is slidedly arranged on said clamp cutter of said clamp cutter of edge and the driving mechanism that is used for driving respectively said clamp cutter and said thread trimmer that are used to clamp enamelled wire.
Further, said clamp cutter comprises tension seat and orders about the line ball head that endwisely slips and match and clamp enamelled wire with said tension seat along said tension seat by driving mechanism.
Further, the end of said line ball head is provided with the projection that is used for fixing enamelled wire, and said tension seat is provided with the groove that matches with said projection.
Further, said driving mechanism is a double stroke cylinder.
Further, said driving mechanism comprises: first cylinder and second cylinder that is used to drive said thread trimmer that are used to drive said clamp cutter.
Further, on said clamp cutter, be provided with when being used for stator and carrying out indexing enamelled wire is fixed to the hook portion in the stator slot.
The utility model adopts driving mechanism to drive clamp cutter and thread trimmer respectively, has the function of clamp and trimming simultaneously, can realize the work of clamp and trimming automatically, and it is flexible and convenient to use, has improved operating efficiency, has practiced thrift cost of labor.

Embodiment
Automatic shearing mechanism to the stator winder of the utility model describes with reference to accompanying drawing.
The automatic shearing mechanism of the stator winder of the utility model as depicted in figs. 1 and 2 comprises: be used to clamp clamp cutter 2, the thread trimmer 3 of enamelled wire 4 and the actuating unit 1 that is used for driving respectively clamp cutter 2 and thread trimmer 3.Wherein, thread trimmer 3 is along on the outer wall that axially is slidedly arranged on clamp cutter 2 of clamp cutter 2, and thread trimmer 3 is used for after clamp cutter 2 clamps enamelled wire 4, it being cut off.
Clamp cutter 2 comprises tension seat 21 and orders about the line ball head 22 that endwisely slips and match and clamp enamelled wire 4 with tension seat 21 along tension seat 21 by driving mechanism.Be provided with the projection 221 that is used for fixing enamelled wire 4 in the end of line ball head 22, on tension seat 21, be provided with the groove 211 that matches with projection 221 accordingly.
During practical implementation, double stroke cylinder be can adopt, clamp cutter 2 and thread trimmer 3 driven respectively as a kind of execution mode driving mechanism 1.Can comprise as another kind of execution mode driving mechanism 1: first cylinder and second cylinder that is used to drive thread trimmer 3 that are used to drive clamp cutter 2.
Comprise that with driving mechanism 1 first cylinder and this execution mode of second cylinder describe clamp and trimming process below.
Fig. 3 and Fig. 4 are the clamp view of automatic shearing mechanism of the stator winder of the utility model.After coiling finishes, press down the end of a thread 22 in the drive of second cylinder and stretch out, the projection 221 of its end is fixed enamelled wire 4.This moment, second cylinder shrank, and line ball head 22 drives enamelled wire 4 and is withdrawn into shown position, and line ball head 22 cooperatively interacts with tension seat 21 enamelled wire 4 is clamped.
Fig. 5 and Fig. 6 are the trimming view of automatic shearing mechanism of the stator winder of the utility model.After enamelled wire 4 was clamped, first cylinder stretched out and drives thread trimmer 3 and move to shown position enamelled wire 4 is cut off.
As shown in Figure 7 on the line ball head 22 of clamp cutter 2, being provided with when being used for stator and carrying out indexing is fixed to the hook portion 23 in the stator slot with enamelled wire 4; Before stator carries out indexing; Pressing down the end of a thread 22 in the drive of second cylinder stretches out; Hook portion 23 catches on enamelled wire 4 and is fixed, and when stator withdrawed from the coiling anchor clamps, enamelled wire 4 can not be drawn out line embedding groove.
The utility model adopts driving mechanism 1 to drive clamp cutter 2 and thread trimmer 3 respectively, has the function of clamp and trimming simultaneously, can realize the work of clamp and trimming automatically, and it is flexible and convenient to use, has improved operating efficiency, has practiced thrift cost of labor.
The above is the embodiment of the utility model; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; Can also make some improvement and retouching, these improvement and retouching also are regarded as the protection range of the utility model.
