Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Principle of the present utility model is: be clamped in by commutator on air spider, then by the radial position of photoelectric sensor detection commutator, then air spider is driven to rotate by servomotor, the radial position of adjustment commutator, after adjusting to the right place, commutator is pressed into by aerostatic press above.These courses of work all control by PLC is unified, so more coherent, efficiency comparison is high, and the precision comparison of photoelectric sensor and servomotor is high, and make the location comparison of commutator accurate, comparison of coherence is good.
Embodiment:
As shown in Figure 1, a kind of commutator pressing tool, comprise aerostatic press and mould bases, mould bases comprises cope match-plate pattern 2, lower bolster 3 and guide pillar 4, cope match-plate pattern 2 is provided with the iron core positioning tube 5 of the radial position of location rotor core 11, the axis being parallel of iron core positioning tube 5 is in the axis of guide pillar 4, and the external diameter of its diameter of bore and rotor core 11 matches; Be provided with servomotor 5 below lower bolster 3, servomotor 5 is fixing on the table, and its axis being parallel is in the axis of guide pillar 4; The output shaft 61 of servomotor is in the upper end of servomotor, and output shaft 61 is fixed with air spider 10, and the Clamping Center of air spider 10 is on the extended line of the axis of iron core positioning tube 5; Lower bolster 3 is provided with the photoelectric sensor 8 of detection commutator radial position, and the position of photoelectric sensor 8 is adjustable; Frock is also provided with PLC (not shown), and the electromagnetically operated valve of the electromagnetically operated valve of PLC and servomotor 6, air spider 10, photoelectric sensor 8 and aerostatic press is electrically connected.
The mould bases of mould bases of the present utility model and standard is similar, can use the mould bases of standard in other words, and the basis of standard die set processes further again.
The axis being parallel of iron core positioning tube 5 is in the axis of guide pillar 4, and the external diameter of its diameter of bore and rotor core 11 matches, and such rotor core 11 can put into iron core positioning tube 5 smoothly, is also convenient to location.Its gap is generally 0.2 ~ 0.3mm, and gap is too large, be then not easy location, gap is too little, then rotor core 11 is put into more difficult.Concrete locate mode is generally the positioning bar arranging corresponding band tapering according to the opening of the wire casing of rotor core 11.
In order to ensure the accurate of the position of iron core positioning tube 5, be generally fixed on cope match-plate pattern 2 by straight pin 51 and soket head cap screw 52.The position of such installation is accurate, and when again installing after dismounting, consistency is good.
In addition, between cope match-plate pattern 2 and lower bolster 3 one section of guide pillar is arranged with Compress Spring 7.Like this after commutator is pressed into place, just can automatically reset, be convenient to place next commutator.This is also a kind of common practice of mould bases.
Frock is also provided with PLC (not shown), and the electromagnetically operated valve of the electromagnetically operated valve of PLC and servomotor 6, air spider 10, photoelectric sensor 8 and aerostatic press is electrically connected.PLC has been unified control action, ensures that each action is coordinated mutually, coordinates, if the signal obtained by photoelectric sensor is had, some are delayed, then can make some when arranging and compensate.Because PLC is also very common industrial control device, do not show in the drawings.
Photoelectric sensor has a variety of, and the utility model also can use multiple photoelectric sensor, and reaches identical object, recommendation color sensor.
The position of photoelectric sensor 8 is adjustable, and this is the commutator in order to adapt to different size, and the air spider etc. by rotating also can be avoided to bump against.
In the present embodiment, output shaft 61 is connected by shaft coupling 62 with air spider 10.This is fairly simple a kind of method of attachment, fixing also reliable.
In the present embodiment, air spider 10 is provided with 2 claws 101.Because clamping commutator, being to drive it to rotate, not needing too large power, and in order to avoid blocking photoelectricity commutator, so be provided with 2 claws 101
In the present embodiment, the clamping face of claw 101 is provided with rubber cover.This is in order to avoid being crushed by commutator.
In the present embodiment, be provided with plane bearing 102 bottom air spider 10, plane bearing 102 can play and support air spider rotation, also can bear pressure during commutator press-in.Certainly this is a kind of fairly simple scheme, and the useful life of plane bearing is not long, but because such commutator is few, so also can accept.
In order to statement clearly, the easy steps of press-in is described below:
1) rotor core assembly (comprising the armature spindle 12 and rotor core 11 that assemble) is put into iron core positioning tube 5;
2) commutator 13 is put into the upper surface of air spider 10;
3) click switch, commutator 13 clamps by the claw 101 of air spider;
4) photoelectric sensor 8 detects the radial position of commutator, and information is sent to PLC;
5) PLC sends the instruction allowing servomotor 6 adjust commutator radial position, and air spider 10, under the drive of servomotor, slowly rotates (speed is very slow, preferably at 1 ~ 10r/min);
6), after commutator 13 forwards the position of regulation to, servomotor stops immediately;
7) the aerostatic press work above, pressure head 9 is descending, and commutator 13 is pressed into rotor core assembly.
When certain reality uses, also need to consider, after commutator press-in, the problem that servomotor can not start, if not so misoperation, can damage rotor core, iron core positioning tube and motor itself, because this is not in the technical solution of the utility model, not be described at this.
In the above-described embodiments, a kind of commutator pressing tool that the utility model provides, commutator is clamped on air spider, then by the radial position of photoelectric sensor detection commutator, air spider is driven to rotate by servomotor again, the radial position of adjustment commutator, after adjusting to the right place, commutator is pressed into by aerostatic press above.These courses of work all control by PLC is unified, so more coherent, efficiency comparison is high, and the precision comparison of photoelectric sensor and servomotor is high, and make the location comparison of commutator accurate, comparison of coherence is good.Its beneficial effect is: the accurate positioning of commutator, reliable, and press-in efficiency is high.
Above-described is only preferred implementation of the present utility model; it should be pointed out that for the person of ordinary skill of the art, under the prerequisite not departing from the utility model creation design; can also make some distortion and improvement, these all belong to protection range of the present utility model.
