The specific embodiment
With mark 1 expression pliers, it has a beader 2 in all accompanying drawings, is used for the crimp of the heart yearn end cover on the end of removing insulating barrier of electric conductor.
Beader 2 has a crimp drum 3, and it can rotate and can move on to an operating position (seeing Fig. 5 and 6) from a resting position (seeing Fig. 1-4) along this axle 4 around one 4.
Support one second movable handle 7 in this external pliers housing 5 swingably, it has a transmission device that does not illustrate again in the front portion that it inserts in the pliers housing 5, this transmission device is provided with a gear pin 8, this gear pin 8 embeds in the dihedral slotted hole 9 of transmission levers 10, and this transmission levers 10 can be along the direction of the arrow A among Fig. 2 and Fig. 4 forward, can return in contrast to this original moving direction after the direction of crimp drum 3 moves and discharging movable handle 7 once more when handling movable handle 7.
Be bearing in the crimp drum 3 of axle on 4 movably and be equipped with at least one drum bearing pin 11 at end face towards the back of transmission levers 10.The moving axially of crimp drum 3 causes engaging of described drum bearing pin and transmission levers 10, and promptly drum bearing pin 11 inserts in the opening 12 of transmission levers 10.Cause the corresponding rotation of crimp drum 3 in the lengthwise movement of the position of this joint transmission levers 10 this moment.
In the position of the joint of drum bearing pin 11 and transmission levers 10, the temporary transient locking of crimp drum and not moving axially.After finishing an impulse stroke, be that transmission levers 10 mobile fully or transmission levers 10 forward turns back to its original resting position fully, cancel the axially locking of crimp drum 3 once more, and make crimp drum 3 turn back to the position that it throws off transmission levers 10 once more by the respective springs loading.
For the crimp of heart yearn end cover, insert realization crimp drum 3 moving axially in the crimp drum to bonding station by a end with electric conductor.
In the resting position of crimp drum 3 and transmission levers 10, drum bearing pin 11 is positioned at the opposite of the enlarged area 12a of opening 12, and this is shown in Fig. 2 and 4 especially significantly.Because the dead size of the enlarged area 12a of opening 12 is greater than the diameter of drum bearing pin 11, but under any circumstance equal fault-free ground inserts drum bearing pin 11 in this zone of openings 12.The operation of transmission levers 10 not only causes transmission levers 10 to the moving of crimp drum 3 directions, and also causes transmission levers 10 to the 11 direction deflections of drum bearing pin by a sliding surface 13 (seeing Fig. 4 and 6) that tilts rising.Whereby the following zone that is equivalent to drum bearing pin 11 diameters of opening 12 enter one with the contact position of drum bearing pin 11, engage thereby reach in fact gapless this moment between the opening 12 of described drum bearing pin 11 and transmission levers 10.
Simplify the embedding of drum bearing pin 11 in the zone of opening 12 on the one hand by such structure, and constitute the exactly determined corner motion that the shift motion that can effectively utilize that makes transmission levers 10 simultaneously converts crimp drum 3 to reliably.
Therefore the manipulation and the use of beader 2 have been simplified on the whole, even and in total system, inevitably also can avoid fault when drum bearing pin 11 inserts openings 12 under the situation of tolerance reliably.
Because the intent of the present invention reached this purpose, omit detailed description to crimp drum and its master control at this.Still can consult EP 0 652 229 B1 once more in this respect, wherein describe whole quite complicated structure and the master control and modes of action of crimp drum in detail.Its relevant description part becomes the application's part clearly in this respect.
As describing in above-mentioned document chapters and sections, a crimp drum 3 generally advantageously has a plurality of moulds, in order to the electric conductor of processing different size.This requires crimp drum 3 can forward different available operating positions to.Therefore correspondingly a crimp drum 3 also is equipped with a plurality of drum bearing pins 11 at its end face towards transmission levers 10, so that all can drive crimp drum 3 reliably on each operating position that occupies.
