Abstract
The invention discloses a segment arranging plastic sleeve of a commutator, which comprises a cylindrical core, the outer circumference of the cylindrical core is provided with evenly-spaced flanges and grooves, and the grooves and cross section structures on the roots of commutator segments in the commutator are matched and positioned. The segment arranging plastic sleeve of the commutator is characterized in that the bottom surfaces of the grooves are conical surfaces, on the upper end face of the cylindrical core, the height of the grooves is larger than the radial dimension of the cross section structures on the roots of the commutator segments, and on the lower end face of the cylindrical core, the height of the grooves is smaller than the radial dimension of the cross section structures on the roots of the commutator segments. The segment arranging plastic sleeve of the commutator is used for arranging the commutator segments in the commutator, and the commutator segments can be automatically fastened and positioned and are not required to be clamped by fasteners after being spread, so that the commutator segment spreading speed and the percent of pass are increased and absence and dropping of the commutator segments after being spread are avoided efficiently.
Description
[technical field]
The present invention relates to the screening plastic sheath of commutator segment screening in the commutator making.
[background technology]
In the manufacturing process of commutator; The screening operation of commutator segment be will with slices independently the commutator segment proper alignment to the screening plastic sheath; The structure of screening plastic sheath is described in detail with using in the patent No. 93120155.1 " slice arranging apparatus of commutator and screening technology thereof ", to have; Because structural design, commutator segment will use fixture (like rubber band, rubber ring etc.) to carry out banding after screening on the screening plastic sheath, could import then to carry out plastic pressure injection in the transfer mould.Its shortcoming is: need after the commutator segment screening with tightening up the thing banding, screening speed is slower, and the axial location of the commutator segment after the screening on plastic sheath can be uneven, occurs defectively easily, and commutator segment lacks easily and comes off after the screening.
[summary of the invention]
In view of the problem that present known technology exists, the technical problem that the present invention will solve is to be to provide after a kind of screening clamped and located automatically, the commutator screening plastic sheath of raising screening speed and qualification rate.
The present invention takes following technical scheme to accomplish:
Commutator screening plastic sheath comprises a cylinder core, and the excircle of cylinder core is provided with equally spaced flange and groove; The cross-sectional structure of commutator segment root cooperates the location in said groove and the commutator; It is characterized in that: the groove bottom of groove is the conical surface, and in the upper surface of cylinder core, the groove of groove is tall and big in the radial dimension of commutator segment root cross-sectional structure; In the lower surface of cylinder core, the groove higher primary school of groove is in the radial dimension of commutator segment root cross-sectional structure.
After adopting technique scheme; In the upper surface of cylinder core, because the groove of groove is tall and big in the radial dimension of commutator segment root cross-sectional structure, so commutator segment can be embedded into from the upper surface direction of cylinder core each groove one by one; Lower surface at the cylinder core; Because the groove higher primary school of groove in the radial dimension of commutator segment root cross-sectional structure, can not come out from the lower surface of cylinder core so embed the commutator segment of groove certainly, commutator segment can be automatically in column type in-core clamped and located; Improved screening speed; Also can effectively prevent the disappearance of commutator segment after the screening and come off, and the axial location of the commutator segment after the screening on plastic sheath can unify neatly very much, improve qualification rate.
As preferably, the tapering of the said conical surface is 0.5 ± 0.1 degree.This tapering can provide the reliable and stable power that tightens up for the commutator segment that embeds in the groove, and guarantees that commutator segment after the screening can import smoothly and carry out plastic pressure injection in the transfer mould.
[description of drawings]
The present invention has following accompanying drawing:
Fig. 1 is a structure chart of the present invention;
Fig. 2 is the axial half sectional view of Fig. 1;
Fig. 3 is the sketch map of commutator segment after screening of the present invention;
Fig. 4 is the axial half sectional view of Fig. 3.
[embodiment]
As shown in the figure, commutator screening plastic sheath of the present invention comprises a cylinder core 1; The excircle of cylinder core 1 is provided with equally spaced flange 2 and groove 3, and the cross-sectional structure of commutator segment 5 root 5a cooperates the location in said groove 3 and the commutator, that is to say that commutator segment 5 root 5a just in time can imbed in the groove 3 of cylinder core; The groove number of cylinder core and the size specification decision of size by commutator; The groove bottom 4 of said groove 3 is the conical surface, and the tapering of the conical surface is 0.5 ± 0.1 degree, generally adopts 0.5 degree; Upper surface at cylinder core 1; The high H of the groove of groove 3 is greater than the radial dimension A of commutator segment 5 root 5a cross-sectional structures, and in the lower surface of cylinder core 1, the high h of the groove of groove 3 is less than the radial dimension A of commutator segment 5 root 5a cross-sectional structures.
The present invention is used for the screening of commutator commutator segment like this: shown in Fig. 3 and 4; The root 5a of commutator segment is embedded into each groove 3 from the upper surface direction of cylinder core 1 one by one; Because the high h of groove groove of cylinder core lower surface is less than the radial dimension A of commutator segment root cross-sectional structure; Can realize automatic clamped and located at a certain ad-hoc location of groove so embed the commutator segment 5 of groove 3; Not only improved screening speed, and tightened up position unified (be after the screening the axial location of commutator segment on plastic sheath unified neat), also can effectively prevent the disappearance of commutator segment after the screening and come off.
