Description
Technical field
The utility model relates to a kind of mill, particularly a kind of on-line direct current motor mill.
Background technology
The commutator face of dc motor is uneven to be the most common failure of dc motor.This fault is owing to the long-term on-line operation of dc motor, and the commutator face friction is inhomogeneous, so just causes commutator face uneven, the phenomenon of blackspot or ablation occurs.The untimely processing of this kind situation, situation is in case deterioration just can cause the brush vibrations, and the spark commutation is bad, can cause brush to collapse angle, cracked, disconnected debating when serious, even may " rise extremely " in brush carrier, directly affect the normal use of dc motor.
When the surface of DC motor commutator arc surface wearing and tearing occur or during the vestige that occurs burning, traditional way is to the dc motor maintenance of rolling off the production line, with fine sandpaper or other polishing equipment commutator face is sand flat polishing, traditional polishing process, the fault efflux time is long, the expense of maintenance is relatively high, and dc motor can not use online in the process of polishing.
The utility model content
The technical problem that the utility model solves has provided a kind of on-line direct current motor mill, and this utility model has realized the on-line grinding of commutator face, and process of lapping does not affect the normal use of dc motor.
For solving the problems of the technologies described above, a kind of on-line direct current motor of the utility model mill, comprise mill body and fixture, described fixture is arranged on a side of mill body, described mill body comprises support, set screw, regulate screw mandrel and grinding stone, described support comprises upper bracket and lower carriage, described grinding stone is arranged in the lower carriage, lower carriage is stretched out in its bottom, described adjusting screw mandrel one end is fixedly connected with grinding stone, the other end passes respectively lower carriage and upper bracket, and fix by set screw, described fixture comprises fastening square and standing screw, described fastening square is arranged on a side of lower carriage, described standing screw one end links to each other with fastening square, and the other end links to each other with the brush holder support of brush by nut.
Be provided with regulating spring on the adjusting screw mandrel between described upper bracket and the lower carriage.So design has certain resilient movement space between grinding stone and the commutator face, has avoided grinding stone to contact with the rigid of commutator face, and the polishing effect is better.
So design, can realize the on-line grinding of DC motor commutator, process of lapping does not affect the normal use of dc motor, the installation simple operations is convenient, reduce the eliminating time of fault, prolonged the cycle of operation of dc motor, also reduced workman's labour intensity simultaneously.
A kind of on-line direct current motor of the utility model mill, overcome and adopted traditional approach long for the polish fault efflux time that brings of DC motor commutator male and fomale(M﹠F), the problems such as the expense height of maintenance, bruting process dc motor can not normally use.It is good to the utlity model has grinding effect, and the time of fixing a breakdown is short, and convenient disassembly can repeatedly use, and maintenance cost is low, and can install and use online.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is a kind of on-line direct current motor of the utility model mill front view;
Fig. 2 is a kind of on-line direct current motor of the utility model mill right view;
Among the figure: 1-nut, 2-upper bracket, 3-standing screw, the fastening square of 4-, 5-lower carriage, 6-regulate screw mandrel, 7-set screw, 8-grinding stone, 9-commutator, 10-regulating spring.
The specific embodiment
Such as Fig. 1, shown in Figure 2, a kind of on-line direct current motor of the utility model mill, comprise mill body and fixture, described fixture is arranged on a side of mill body, described mill body comprises support, set screw 7, regulate screw mandrel 6 and grinding stone 8, described support comprises upper bracket 2 and lower carriage 5, described grinding stone 8 is arranged in the lower carriage 5, lower carriage 5 is stretched out in its bottom, described adjusting screw mandrel 6 one ends are fixedly connected with grinding stone 8, the other end passes respectively lower carriage 5 and upper bracket 2, and fixing by set screw 7, described fixture comprises fastening square 4 and standing screw 3, described fastening square 4 is arranged on a side of lower carriage 5, described standing screw 3 one ends link to each other with fastening square 4, and the other end links to each other with the brush holder support of brush by nut 1.
Be provided with regulating spring 10 on the adjusting screw mandrel 7 between described upper bracket 2 and the lower carriage 5.So design has certain resilient movement space between grinding stone 8 and commutator 9 surfaces, has avoided rigid the contacting of grinding stone 8 with commutator 9 surfaces, and the polishing effect is better.
Described support is consistent with the brush carrier profile of motor.The same with the brush carrier mounting means, do not affect the normal operation of dc motor in the process of lapping.
Determine the commutator position that needs grind and the position that mill is installed according to motor ruuning situation; Utilize roll change or downtime, mill is installed, change the brush carrier of this position with mill, and carefully adjust, make grinding stone 8 and commutator 9 surfaces leave the 1mm distance during installation and guarantee that mill installs firmly; Behind the motor operation, prop up grinding stone 8 with the insulation bottle opener, observe the amplitude of beating, slowly adjust the set screw 7 on mill top, as feel vibration, then represent grinding stone 8 with commutator 9 Surface Contacts, prop up grinding stone 8 upper ends with the insulation bottle opener simultaneously, and then adjust set screw 7, each 0.5-1 circle of adjusting, observe other brushes in same brush road, until no longer beat, this brush road grinds and finishes; Recycling roll change or downtime, remove mill, recover original brush and brush carrier and get final product.
