Wire binding machine for stator rocking-arm driving mechanism
Technical field
The utility model belongs to plant equipment transmission field, is specifically related to a kind of rocking-arm driving mechanism of wire binding machine for stator.
Background technology
There is loose situation in the coil groups in order to avoid motor stator, current stator manufacturer all can carry out wiring work to the stator after coiling, specifically refer to and carry out binding work with fine rule around coil groups, these manufacturer's majorities have been introduced mechanized equipment and have been completed the work of stator wiring.Current wire binding machine for stator outputs to working distal tip as the transmission process wiring crochet hook, line sending mouth etc. from motor power, and the general composition of cam and rocking arm that uses completes.Because cam has unicity, each cam can only arrange a kind of gradient (highly), which results in when the stator for differing heights size carries out wiring, often needs to change cam, bothers very much.
Strengthen to make the versatility of wire binding machine for stator, sometimes the mode of cam and rocking arm is replaced to be socketed transmission with vertical screw mandrel: by the height of Serve Motor Control screw mandrel thus the flexible amplitude of oscillation controlling rocking arm, but due in the course of the work often will repeatedly back and forth movement at wire binding machine for stator, and in this structure rocking arm and the center of gravity of working distal tip all concentrate on the output point of screw mandrel, therefore screw mandrel is very easy to occur wearing and tearing, because working distal tip is in the distal end of lever of rocking arm, therefore, when wearing and tearing appear in screw mandrel, the deviation of working distal tip is just very large.
Utility model content
Not enough for above-mentioned prior art, it is simple that the technical problems to be solved in the utility model is to provide a kind of wire binding machine for stator rocking-arm driving mechanism structure, and stability is strong, can rotate the amplitude of oscillation of rocking arm according to stator Height Adjustment, practical.
For achieving the above object, the utility model adopts following technical scheme:
Wire binding machine for stator rocking-arm driving mechanism, comprise support, servomotor, rocking arm, rocker arm support, it is characterized in that: also comprise bearing holder (housing, cover), described servomotor is fixedly connected with support, described servomotor center shaft and described bearing holder (housing, cover) pivot joint, described bearing holder (housing, cover) has eccentric output shaft, described one end and described rocker arm support pivot joint become fulcrum, described rocking arm has the first mobile channels be socketed with described eccentric output shaft, and described rocking arm has the rocking arm connecting portion be flexibly connected with described wire binding machine for stator working distal tip relative to the other end.The combination using capacity eccentric bearing and rocking arm to be socketed replaces conventional cam, the amplitude of oscillation of rocking arm is realized adjustable, simultaneously because bearing holder (housing, cover) uses eccentric output shaft, the stressed effect of rigidity output shaft is better, the stability of transmission mechanism is guaranteed, avoids the directly stressed of servomotor shaft simultaneously.
Described wire binding machine for stator working distal tip specifically refers to wiring crochet hook assembly or the line sending assembly of wire binding machine for stator, the second mobile channels that described rocking arm connecting portion is specifically socketed with described crochet hook assembly, line sending assembly respectively, the 3rd mobile channels.
Described support, servomotor, rocking arm, rocker arm support, bearing holder (housing, cover) and annexation thereof respectively specular arrange another group, provide transmission for the upper and lower two-sided wiring work for wiring stator.
Wire binding machine for stator rocking-arm driving mechanism of the present utility model, beneficial effect is as follows:
1, instead of traditional cam drive structure, achieve the rocking arm amplitude of oscillation adjustable, the stator wiring work of sizes, height can be used for.
2, bearing holder (housing, cover) uses eccentric shaft, and relatively existing vertical screw mandrel regulates more firm, stable, even if eccentric shaft has certain wearing and tearing, does not also affect wire binding machine normal operation.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model wire binding machine for stator rocking-arm driving mechanism.
Wherein, 1, servomotor; 2, rocking arm; 21, the first mobile channels; 22, the second mobile channels; 23, the 3rd mobile channels 3, rocker arm support; 4, bearing holder (housing, cover); 41, eccentric output shaft.
Embodiment
As shown in Figure 1, wire binding machine for stator rocking arm 2 transmission mechanism of the present utility model, comprise support (figure does not show), servomotor 1, rocking arm 2, rocker arm support 3, it is characterized in that: also comprise bearing holder (housing, cover) 4, described servomotor 1 is fixedly connected with support, described servomotor 1 center shaft and described bearing holder (housing, cover) 4 pivot joint, described bearing holder (housing, cover) 4 has eccentric output shaft 41, described rocking arm 2 one end and described rocker arm support 3 pivot joint become fulcrum, described rocking arm 2 has the first mobile channels 21 be socketed with described eccentric output shaft 41, the described rocking arm 2 relatively other end has rocking arm 2 connecting portion be flexibly connected with described wire binding machine for stator working distal tip.The combination using capacity eccentric bearing and rocking arm 2 to be socketed replaces conventional cam, the amplitude of oscillation of rocking arm 2 is realized adjustable, simultaneously because bearing holder (housing, cover) 4 uses eccentric output shaft 41, the stressed effect of rigidity output shaft is better, the stability of transmission mechanism is guaranteed, avoids the directly stressed of servomotor 1 shaft simultaneously.
Described wire binding machine for stator working distal tip specifically refers to wiring crochet hook assembly or the line sending assembly of wire binding machine for stator, the second mobile channels 22 that described rocking arm 2 connecting portion is specifically socketed with described crochet hook assembly, line sending assembly respectively, the 3rd mobile channels 23.
Described support, servomotor 1, rocking arm 2, rocker arm support 3, bearing holder (housing, cover) 4 and annexation thereof respectively specular arrange another group, provide transmission for the upper and lower two-sided wiring work for wiring stator.
Wire binding machine for stator rocking-arm driving mechanism structure of the present utility model is simple, and stability is strong, can rotate the amplitude of oscillation of rocking arm according to stator Height Adjustment, practical.
To one skilled in the art, according to technical scheme described above and design, other various corresponding change and deformation can be made, and all these change and deformation all should belong within the protection range of the utility model claim.
