Description
Technical field
The utility model relates to a kind of drive unit for carbon brush for electric machine wear test.
Background technology
Along with the development of automated production, carbon brush, except being used widely on motor, also gets more and more in the application of other occasions.In power on/off, normal pressure and working environment, various inevitable lubrications etc. all can make carbon brush produce wearing and tearing frequently, and in the occasion that some is special, the far super imagination of the rate of wear of carbon brush, have impact on production efficiency.
The motion way of realization of the existing testing machine about carbon brush abrasion, mainly contain rotary type and reciprocating, the reciprocating one-way abrasion that cannot realize carbon brush, though rotary type can realize the one-way abrasion of carbon brush, can not simulate the wear working condition of straight reciprocating motion carbon brush completely.And also there is certain defect in the driver module of existing straight reciprocating motion carbon brush Work condition analogue: all cannot the stroke of dynamic conditioning straight reciprocating motion.
Utility model content
The utility model is intended to provide a kind of carbon brush for electric machine wear test engine, to drive carbon brush linear reciprocating motion in wear test, and the reciprocating stroke of the adjustment of dynamic.
Carbon brush for electric machine wear test engine in this programme, comprise housing, housing is provided with motor, the output shaft of motor is connected with cam, the cam follower be connected on housing that slides axially withstands on cam, the driven end of cam follower and the cylindrical void of rocking bar drive end hinged, on rocking bar, the driven end of drive end opposite end is also provided with cylindrical void, take-off lever also slides axially and is connected on housing, the drive end of take-off lever and the cylindrical void of rocking bar driven end hinged, the driven end of take-off lever stretches out housing and to be used as power output, the middle part of rocking bar has been slidably connected slide block, slide block and bearing hinged, bearing and housing are that linear slide connects.
In said mechanism, motor as driving link outputting power, actuated by cams cam follower axially reciprocating, then drive rocker reciprocally swinging within the scope of certain angle, last driver output bar carries out linear reciprocation action, drives carbon brush linear reciprocating motion in wear test.More crucially, this programme can by regulating the displacement of bearing, with change rocking bar swing pivot, the brachium of lever is changed, realizes the dynamic conditioning of take-off lever rectilinear motion stroke.
Further, housing upper rotary is connected with screw mandrel, screw mandrel and bearing thread connection.The linear displacement of bearing can be adjusted by rotary screw, reach the object changing take-off lever rectilinear motion stroke.
Further, slide block is provided with chute, chute connects with rocking bar linear slide, the periphery on slide block and bearing hinged.Compact structure can the volume of reduction equipment greatly.
Further, one end that cam follower and cam offset is provided with pulley.The attrition in the course of work can be reduced.
Accompanying drawing explanation
Fig. 1 is the schematic front view of the utility model embodiment.
Embodiment
Below by embodiment, the utility model is described in further detail:
Reference numeral in Figure of description comprises: housing 1, offset cam 2, cam follower 3, extension spring 31, pulley 4, rocking bar 5, take-off lever 6, sliding sleeve 7, bearing 8, guide rail 9, leading screw 10.
Embodiment is substantially as shown in Figure 1: on square housing 1, be provided with motor, motor is not shown in the drawings, the output shaft of motor is perpendicular to drawing plane, output shaft has been fixedly connected an offset cam 2, it is the pulley 4 of cam follower 3 that the below of offset cam 2 offsets with it, through hole on cam follower and housing is slidably matched, between be also connected with an extension spring 31, to ensure that cam follower 3 holds out against on offset cam 2.
The lower end of cam follower 3 and the cylindrical void of rocking bar 5 right-hand member carry out hinged, and the meaning of cylindrical void produces unnecessary pressure to cam follower 3 after being to avoid rocking bar 5 to shake in the horizontal direction.What the left end of rocking bar 5 was same is provided with cylindrical void, and carries out hinged with take-off lever 6, and take-off lever 6 is also slidably connected with the through hole on housing 1, and vertically leads to take-off lever, and housing is stretched out to external work in the upper end of take-off lever.
For realizing the dynamic conditioning of take-off lever rectilinear motion stroke, in this programme, most important structure is: the middle part of rocking bar 5 is slidably connected circular sliding sleeve 7, the middle part of sliding sleeve 7 is run through has square groove and rocking bar 5 to be slidably matched, the outside surface of sliding sleeve 7 is circular, and the arcwall face coordination hinge on above-below direction and bearing 8.In such a configuration, can straight line relative movement between sliding sleeve 7 and rocking bar 5, relative rotation can be there is between sliding sleeve 7 with bearing 8.Meanwhile, also linear slide is on horizontal guide rail 9 for bearing 8, and leading screw 10 carries out thread connection through housing 1 and bearing 8, and leading screw is provided with the handwheel that convenient operation personnel turn in the outside of housing.In above-mentioned structure, rotate handwheel and order about screw turns, by the thread connection between leading screw and bearing, torque axis is turned to linear thrust, move linearly about making bearing, thus change the swing pivot of rocking bar, realize the dynamic conditioning of take-off lever rectilinear motion stroke.
Above-described is only embodiment of the present utility model, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the prerequisite not departing from the utility model structure, some distortion and improvement can also be made; these also should be considered as protection domain of the present utility model, and these all can not affect effect and the practical applicability of the utility model enforcement.The protection domain that this application claims should be as the criterion with the content of its claim, and the embodiment in instructions etc. record the content that may be used for explaining claim.
