Abstract
The utility model discloses an outer circular face turning device for a micro-motor rotor commutator. The outer circular face turning device comprises an X-direction finishing tool, a belt and a pulley and is characterized in that the pulley is connected with a bidirectional rotating device. The X-direction finishing tool includes a left finishing tool and a right finishing tool. Compared with the prior art, bidirectional (left rotating and right rotating) mesh cutting grains are generated on the outer circular face after turning. Notch burr of commutator can be reduced. During operation of a micro-motor and contact of the outer circular face of the commutator with a carbon brush, noise and spark are reduced effectively.
Description
Technical field
The utility model relates to a kind of truning fixture, relates in particular to a kind of micro-motor rotor commutator cylindrical surface truning fixture, belongs to mechanical field.
Background technology
Existing processing technology is that the micro-motor rotor commutator cylindrical is carried out the unidirectional turning of hilted broadsword, pressure arm belt single direction rotation.After the turning, the commutator cylindrical surface produces the spiral knife mark of one direction (left-handed or dextrorotation), and the notch at commutator produces serious burr easily.When micro machine turns round, in the contact process of commutator cylindrical surface and carbon brush, produce serious noise and spark.
The utility model content
The utility model provides a kind of micro-motor rotor commutator cylindrical surface truning fixture in order to solve the above-mentioned deficiency of prior art.
Above-mentioned purpose of the present utility model realizes by following technical scheme: a kind of micro-motor rotor commutator cylindrical surface truning fixture, comprise X-direction finishing tool, belt and belt pulley, it is characterized in that: described belt pulley connects two-way rotating device, and described X-direction finishing tool comprises left finishing tool and right finishing tool.
Turning was divided into for two steps: at first, during a turning, left finishing tool can go out left-handed knife mark in commutator cylindrical surface turning; Secondly, during secondary turning, right finishing tool can go out the dextrorotation knife mark in commutator cylindrical surface turning.The effect of comprehensive twice turning can make the commutator cylindrical surface produce netted knife mark.Netted knife mark can reduce the burr of commutator notch; When micro machine turns round, in the contact process of commutator finished surface and carbon brush, effectively reduce noise and spark.
The utility model advantage compared with prior art is: after the turning, the commutator cylindrical surface produces the netted knife mark of twocouese (left-handed and dextrorotation).Can reduce the burr of commutator notch.When micro machine turns round, in the contact process of commutator cylindrical surface and carbon brush, effectively reduce noise and spark.
Description of drawings
Fig. 1 is the structural representation of a turning of the utility model embodiment;
Fig. 2 is the structural representation of the utility model embodiment secondary turning.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail:
As shown in Figure 1 and Figure 2, a kind of micro-motor rotor commutator cylindrical surface truning fixture, comprise X-direction finishing tool 1, belt 2 and belt pulley 3, it is characterized in that: described belt pulley 3 connects two-way rotating device 4, and described X-direction finishing tool 1 comprises left finishing tool 11 and right finishing tool 12.
Turning was divided into for two steps: at first, during a turning, left finishing tool 11 can go out left-handed knife mark in commutator 5 outer round surface turning; Secondly, during secondary turning, right finishing tool 12 can go out the dextrorotation knife mark in commutator 5 outer round surface turning.The effect of comprehensive twice turning can make commutator 5 outer round surface produce netted knife mark.Netted knife mark can reduce the burr of commutator notch; When micro machine turns round, in the contact process of commutator 5 finished surfaces and carbon brush, effectively reduce noise and spark.
But the above-mentioned specific embodiment is exemplary, is to be the restriction that this patent is comprised scope in order better to make those skilled in the art can understand this patent, can not to be interpreted as; So long as according to spirit that this patent discloses do anyly be equal to change or modify, all fall into the scope that this patent comprises.
Claims (1)
1. a micro-motor rotor commutator cylindrical surface truning fixture comprises X-direction finishing tool, belt and belt pulley, and it is characterized in that: described belt pulley connects two-way rotating device, and described X-direction finishing tool comprises left finishing tool and right finishing tool.
