Abstract

The utility model relates to a ring collector assembling device. In the utility model, a base plate 1 of a pressing machine is fixed with a limit seat 5, the upper part of the limit seat 5 is provided with a hole 5-1 used for placing pressing rings and pole pieces, the edge of the hole is uniformly distributed with a limit groove 5-2, the inner part of a center hole of the limit seat 5 is provided with a guide material returning shaft 6, an upper punch 10 of the pressing machine is provided with an upper pressing sleeve 11, the inner part of a center hole of the upper pressing sleeve is provided with a mandrel 7, one end of the mandrel tightly matches and us fixed with an upper positioning piece 8, and the edge of a center hole of the positioning piece 8 is uniformly distributed with limit holes 8-1 used for positioning frameworks. The utility model is used for substituting for manual assembly and has the advantages of time saving, labor saving and once placing of pressing rings, and the utility model enhances production efficiency. The limit groove on the limit seat causes triple-pole pieces used for assembling ring collectors to be uniformly distributed, and the utility model has high precision.

Description

The commutator assembly equipment

The utility model belongs to the process equipment in the electrical micro-machine technology, is specifically related to a kind of commutator assembly equipment.

Commutator (claiming commutator again) is the vitals of electrical micro-machine, and it is made up of pole piece, skeleton and trim ring three parts.Pole piece should be distributed on the skeleton evenly, reliably, and cut must not be arranged.

At present, commutator adopts method manual or the machinery assembling to assemble.Manual method is: three pole pieces are respectively charged into skeleton, trim ring are packed into be with on the skeleton of pole piece again.Its subject matter is:

1. assembling difficulty, production efficiency is low, and pole piece and trim ring very easily damage.When pole piece being inserted skeleton with hand, very inconvenient during installation because pole piece is very little, not only to require great effort but also time-consuming, production efficiency is very low; Simultaneously, hole dimension is identical with skeleton external diameter behind the pole piece of packing in the trim ring, is pressed into trim ring by hand, and assembling is difficult; In addition, pole piece is packed into fixing not firm behind the skeleton, as easy as rolling off a log damage pole piece or trim ring when trim ring is pressed into, and the waste raw material increase production cost.

2. hand assembled is inserted skeleton by hand with pole piece fully, does not have positioner, is difficult to guarantee that three pole pieces are evenly distributed, and can not guarantee the required precision of commutator, has influenced the precision of motor.

The assembling of present machinery, its principle is identical with hand assembled, also is with the pole piece skeleton of packing into, utilizes mechanical device that trim ring is pressed into then.Only be to have replaced manual trim ring with the difference of manual method with mechanical trim ring, though improved production efficiency, but still have the other problem of hand assembled, very easily impaired as pole piece and trim ring, waste material increases cost, and precision is difficult to guarantee.

The utility model provides the commutator assembly equipment that the commutator cost is low, precision is high of a kind of packaging efficiency height, assembling at the deficiency of the assemble method of existing commutator.

Commutator assembly equipment of the present utility model, it is characterized in that on the base plate of forcing press lower bottom base, fixing a stairstepping cylinder limit base, this limit base upper end is provided with a hole that is used for laying trim ring and pole piece, establish the stopper slot that pole piece is located in three uniform being used at the edge in this hole, in the central through hole of limit base, be provided with stairstepping cylinder guiding material returned axle, the upper end that its small end passes the central through hole of limit base and exposes limit base is provided with a spring under the blind hole at its big end center; Establish gland at the upper punch of forcing press, a mandrel is set in the centre bore of gland on this, mandrel one end of the gland spacer on that is tightly fixed on exposing, the edge of the centre bore of this spacer has three uniform being used to locate the spacing hole of skeleton.

Adopt the utility model commutator assembly equipment to replace hand assembled, not only time saving and energy saving, but the trim ring one-time-reach-place has improved production efficiency widely; Owing to three stopper slots are arranged on limit base, have guaranteed that commutator three pole pieces after the assembling are evenly distributed; Moving surface is the inner surface of skeleton and pole piece when assembling, thereby has guaranteed that the pole piece outer surface can not scratch; The damage of the locating detent on the skeleton that has occurred easily when also having avoided hand assembled and the distortion of the utmost point pawl on the pole piece, thereby guaranteed the precision of commutator;

Below in conjunction with accompanying drawing commutator assembly equipment of the present utility model is described further:

Fig. 1 is the structural representation of commutator, comprises skeleton A1, pole piece A2 and trim ring A3.

Fig. 2 is the structural representation of the utility model commutator assembly equipment.

As shown in Figure 2, commutator assembly equipment of the present utility model, on the base plate 1 of forcing press lower bottom base 9, fix a stairstepping cylinder limit base 5, this limit base upper end is provided with a hole 5-1 who is used for laying trim ring and pole piece, establish the stopper slot 5-2 that pole piece is located in three uniform being used at the edge in this hole, in the central through hole of limit base 5, be provided with stairstepping cylinder guiding material returned axle 6, the upper end that its small end passes the central through hole of limit base 5 and exposes limit base is provided with a spring 4 under the blind hole at its big end center; Establish gland 11 at the upper punch 10 of forcing press, one mandrel 7 is set in the centre bore of gland on this, mandrel one end of the gland spacer 8 on that is tightly fixed on exposing, the edge of the centre bore of this spacer 8 has three uniform being used to locate the spacing hole 8-1 of skeleton.

When operation, at first trim ring is put into limit base 5, again three pole pieces (utmost point pawl upwards) are put into limit base 5 respectively, and the utmost point pawl that makes pole piece falls in three stopper slot 5-2 of limit base 5, skeleton is aimed at mandrel 7 upwards to be put on the spacer 8, and two locating detents that make skeleton insert in the location hole 8-1 of spacer 8, driving skeleton by the drift on the forcing press 10 then moves downward, up to pole piece is pressed in the skeleton, retract the position on the forcing press upper punch 10, guiding material returned axle 6 is released commutator by the spring 4 of below, takes off commutator and puts into magazine.
