Abstract
The invention discloses a manufacturing process of a commutator. The manufacturing process is characterized in that processing steps are: 1) coining a preset groove on two sides of a working surface of a commutator bar; 2) arranging the commutator bars on a row piece core, fixing the commutator bars with elastic fastening rings; 3) putting the arranged commutator bars in a mould, taking out the fastening rings and the row piece core; 4) adding bakelite powder, performing compression moulding on the commutator bars and the bakelite powder; 5) performing milling groove along the preset grooves among the commutator bars. Compared with the prior art, the manufacturing process reduces production cost, improves work efficiency, and brings economic benefits for manufacturers.
Description
Technical field
What the present invention relates to is a kind of manufacture craft of commutator, particularly be a kind of motor manufacture craft with no mica commutator.
Background technology
The commutator segment of existing overall plastic hook commutator adopts the plastic sheath screening, promptly adopts manual work that commutator segment is arranged in the plastic sheath, with reference to Fig. 1; Will connect plastic sheath after sequencing and drive in mould together, plastic sheath divested behind the compression molding again, therefore every plastic sheath can only use disposable; So both increased cost of labor, and increased material cost again, artificial removal's plastic sheath brings very big inconvenience; Increase working strength of workers, reduced production efficiency.
Summary of the invention
In view of the existing technical problem of background technology, technical problem to be solved by this invention provides a kind of reducing production costs, and reduces working strength of workers, the manufacture craft of the commutator of enhancing productivity.
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme to realize: the manufacture craft of this kind commutator is characterized in that its processing step is:
1) at the preset groove of the both sides punching out of the working face of commutator segment;
2) commutator segment is arranged on the screening core, fixes with the elasticity tight loop then;
3) will arrange good commutator segment and place in the mould, elasticity tight loop and screening core take out;
4) pour phenolic moulding powder, commutator segment and phenolic moulding powder compression moulding;
5) carry out groove milling along the preset groove between the commutator segment.
6) crotch moulding.
Commutator segment of the present invention is arranged on the screening core, and the screening core is conventional commutator segment screening core, therefore can adopt automatic screening machine to come screening, thereby enhance productivity; Adopt elasticity tight loop location after screening is accomplished, when filling phenolic moulding powder, commutator segment is placed in the mould, elasticity tight loop and screening core are taken out; Thereby elasticity tight loop and all ability quilt uses repeatedly of screening core; Can not cause waste, reduce production cost, and omit divesting of plastic sheath; Reduce working strength of workers, improved production efficiency.The present invention's punching out on commutator segment goes out preset groove, and when filling phenolic moulding powder, phenolic moulding powder can get in this preset groove; Therefore the surperficial equal distribution of the commutator of compression moulding has phenolic moulding powder; Like this in groove milling, detect the phenolic moulding powder of commutator face through photocell eye, and this place that is filled with phenolic moulding powder is carried out groove milling; The position that is groove milling just is the preset groove between the commutator segment, thereby the groove milling position is accurate; Processing hook commutator also need carry out the crotch forming step after groove milling.

Embodiment
The manufacture craft of this kind commutator, its processing step is:
1) at the preset groove 3 of the both sides punching out of the working face of commutator segment 2, with reference to Fig. 3;
2) commutator segment 2 is arranged on the screening core 4, fixes with the elasticity tight loop then, screening core 4 is conventional commutator segment screening core; Therefore can adopt automatic screening machine to come screening; Thereby having improved production efficiency, in the present embodiment, said elasticity tight loop is an elastic tape;
3) will arrange good commutator segment 2 and place in the mould, elasticity tight loop and screening core take out, and all can be used again, thereby reduce production cost;
4) pour phenolic moulding powder 1, commutator segment 2 and phenolic moulding powder 1 compression moulding are because commutator segment 2 is provided with preset groove 3; Therefore when filling phenolic moulding powder 1; Phenolic moulding powder 1 get into should preset groove 3 in, phenolic moulding powder 1 along the circumferential direction equal distribution on the surface of the commutator of moulding, with reference to Fig. 5;
5) carry out groove milling along the preset groove between the commutator segment 3; Since commutator segment 2 conductions, and phenolic moulding powder 1 is insulator, and milling cutter carries out groove milling to this place when photocell eye detects the phenolic moulding powder 1 of commutator face, so the position of groove milling is very precisely, deviation can not occur.
If processing hook commutator after groove milling, carries out crotch 5 moulding, promptly realize the crotch moulding through the crotch mould.
The present invention can adopt the automatic screening of screening machine, has improved production efficiency, when filling phenolic moulding powder 1; The commutator segment 2 of accomplishing screening is inserted in the mould, and remove elasticity tight loop and screening core, so elasticity tight loop and screening core all can be repeated utilization; Cut the waste, reduce production costs, and omitted divesting of plastic sheath; Reduce working strength of workers, improved production efficiency; The present invention follows the tracks of phenolic moulding powder through photocell eye when groove milling, make milling cutter accurately aim at the groove milling position of commutator, and promptly commutator face is filled with the position of the preset groove of phenolic moulding powder, thereby the groove milling position is accurate, and rate of finished products is high.
