Abstract
The invention discloses a commutator segment of a hook commutator, comprising a commutator segment body (1) and a commutator segment hook part (2). Two sides of a hook position of the commutator segment hook part (2) are provided with recessed circular arc grooves (3), and the hook position (4) of the formed hook of the commutator segment hook part is in an arc shape or an arc body without creasing or burrs and is smooth and even and reliable in intensity, thereby improving the practicability of the commutator segment, effectively protecting an enamelled wire, enhancing the quality of a commutator product and prolonging the service life of a motor. Because the hook position of the formed hook of the commutator segment is in the arc shape or the arc body, the enamelled wire is more attachably and tightly wound, which reduces the winding length of the enamelled wire and achieves the effects of saving materials and effectively reduces costs. After the commutator segment hook part is hooked, the steps of eliminating the burrs and polishing are unnecessary, therefore, working hours and costs are reduced, and the production benefits and the market competitiveness of a product are enhanced.
Description
Technical field
The present invention relates to the commutator that a kind of motor is used, specifically relate to a kind of commutator segment of hook commutator.
Background technology
At present, processing procedure operation (the comprising crotch) post of the commutator that motor is used (claiming commutator again) industry be the commutator final finished generate cause the pass important step, with orderly cylindrical arrangement, directivity differentiation about existing and the insulating properties between copper body and the copper body concern in structure for it.In motor, to decide enamelled wire by the commutator segment crotch place hook of hook commutator and be wrapped on the rotor, the voltage that makes motor produce rectification runs well.The both sides of the commutator segment of known hook commutator commutator segment hook portion before crotch are linearity, crotch place after its commutator segment crotch moulding is unsmooth and have fold, burr etc., then easily make enamelled wire decide damaged in the process, incised wound at hook, cause the naked copper oxidation of enamelled wire and influenced the quality of cummutation of motor, and shorten motor useful life.Therefore, commutator requires smooth smooth, the no burr in commutator segment crotch place, also should increase technologies such as deburring, polishing in the manufacturing.These also are the difficult point problem that the amount of labour used is big in the industry operation, benefit is not high, quality is difficult for assurance, the post management cost is difficult to compress undoubtedly.
Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, and provide a kind of make enamelled wire commutator segment crotch place hook decide in the process not can be damaged, the commutator segment of the hook commutator of incised wound.
The object of the invention is achieved through the following technical solutions: a kind of commutator segment of hook commutator, comprise commutator segment body, commutator segment hook portion, the arc groove that the dual-side of described commutator segment hook portion at its crotch place has indent, and the crotch place of this commutator segment hook portion after its crotch moulding is arc shaped or arc body and no wrinkle, no burr.
After adopting the present invention; the crotch place of commutator segment hook portion has the arc groove of indent; in the crotch forming process of commutator segment hook portion, played the effect that this arc groove is enriched in rounding off, extruding; so that (cheicers place) no burr after this crotch place crotch moulding, smooth smooth-going, intensity is reliable; improved the practicality of commutator segment; can not destroy the enamelled wire surface; the enamelled wire hook is surely by arc surface, sound and reliable; protect enamelled wire effectively better; thereby improve the quality of commutator product, increase the useful life of motor.Crotch place after the moulding of commutator segment crotch is arc shaped or arc body, makes detouring of enamelled wire have more applying, sturdy, has reduced the enamelled wire length that detours, the effect that reach economical with materials, effectively reduces cost.And need not carry out operations such as deburring, polishing again behind the commutator segment hook portion crotch, save man-hour, cost, thereby improved productivity effect and product market competitiveness.
The present invention has overcome the difficult point problem that the amount of labour used is big, benefit is not high, quality is difficult for assurance, cost is difficult to compress that perplexs the commutator industry for a long time owing to commutator segment crotch technology, has outstanding characteristics, significant technological progress and beneficial effect.
Description of drawings
The present invention is described in further detail below in conjunction with accompanying drawing and execution mode.
Fig. 1 is the structural representation of the commutator segment (its hook portion both sides are linearity) of known hook commutator.
Fig. 2 is the structural representation after the commutator segment crotch of known hook commutator is shaped.
Fig. 3 is the structural representation of the commutator segment (dual-side at its crotch place has the indent arc groove) of hook commutator of the present invention.
Fig. 4 is the structural representation after the commutator segment crotch of hook commutator of the present invention is shaped.
Fig. 5 is the part side-looking enlarged drawing of Fig. 4.
Fig. 6 is the structural representation after the commutator segment crotch of known hook commutator winds the line.
Fig. 7 is the structural representation after the commutator segment hook portion of hook commutator of the present invention winds the line.
Fig. 8 is applied to the structural representation of commutator after the part coiling for the present invention.
Embodiment
As Fig. 1, Fig. 2, shown in Figure 6, the both sides of the commutator segment of known hook commutator commutator segment hook portion before crotch are linearity, crotch place after its commutator segment crotch moulding is unsmooth and have fold, burr etc. (also may yielding fracture), then easily make enamelled wire the commutator hook decide damaged in the process, hurt.And the enamelled wire that this commutator uses in coupling rotor process strengthens and extends because the fold burr at commutator segment crotch place is the length that detours that square body factor makes enamelled wire, and has also wasted the enamelled wire material to a certain extent.
With reference to Fig. 3 to Fig. 5 as can be known, the commutator segment of hook commutator of the present invention, comprise commutator segment body 1, commutator segment hook portion 2, the dual-side of described commutator segment hook portion 2 at its crotch place has the arc groove 3 when crotch (refer to as yet not) of indent, and the crotch place 4 (particularly crotch cheicers place) of this commutator segment hook portion after its crotch moulding is arc shaped or arc body and no wrinkle, no burr (being smooth smooth-going).
As Fig. 7, shown in Figure 8, the commutator segment of hook commutator of the present invention is applied to the hook commutator, and after the part coiling, make detouring of enamelled wire have more applying, sturdy, reduced the enamelled wire length that detours, saved material, improve quality, the productivity effect of commutator product, saved production cost etc.
The above embodiment, the present invention embodiment a kind of more preferably just, the specifications vary that the technology implementation of this area is carried out in the technical solution of the present invention scope and replacing all should be included in protection scope of the present invention.
Claims (1)
1. the commutator segment of a hook commutator, comprise commutator segment body (1), commutator segment hook portion (2), it is characterized in that: the dual-side of described commutator segment hook portion (2) at its crotch place has the arc groove (3) of indent, and the crotch place (4) of this commutator segment hook portion after its crotch moulding is arc shaped or arc body and no wrinkle, no burr.
