Rotate rotating bar to a baffle side, the shaft coupling rotates in the counterclockwise direction so that rotating bar turns to another baffle side
Dynamic, when motor is placed on positioning seat, the output shaft and shaft coupling of motor are coaxial.
Carry out apparatus of the present invention in use, being placed on positioning seat and carrying out matching for output shaft and shaft coupling for motor
It closes, then carries out the energization of motor, detection workman can grasp rotating bar before electrical power so that rotating bar is located at shaft coupling
Right above device, after electrical power, if rotating bar illustrates the non-rosin joint of commutator in rotor effect lower edge rotation；If rectification
Fictitious weldering, due to not being able to maintain equilbrium position, the effect that rotating bar can not stress immediately under the action of magnet steel and rotor windings；Such as
The welding of fruit commutator is reliable, by Ampere's law it is found that rotor can be always in a state of stress, judges whether commutator is empty in view of this
Weldering.
Preferably, the rotation rod axis and shaft coupling axis are formed with angle, the length of the rotating bar is greater than gear
Plate between shaft coupling at a distance from.Observation when above-mentioned setting rotates rotating bar convenient for detection workman.
Preferably, being equipped with briquetting on the upside of the positioning seat, the positioning seat is formed with perforative positioning in left-right direction
Slot, the briquetting are collocated with driving mechanism or fast clip tool with being fixed for motor.Briquetting is used to compress in motor, with
Shaking when electrical power being avoided to rotate.
Preferably, the power electric connection has positive direction power change-over switch, the rotational angle of the rotating bar is greater than
Or it is equal to 180 °, the average height of two baffles is lower than the height of shaft coupling.Some motors have a pair of of carbon brush, some motor tools
It could judge whether commutator works after thering are two pairs of carbon brush, some motors to only have output shaft to rotate 180 degree.Above-mentioned setting is so that originally
Invention device can be used for the commutator rosin joint detection of more kinds of motors.Wherein, defeated to guarantee by positive and negative rotation power change-over switch
Rotating bar can be made to carry out 180 ° of rotation in shaft main story or reversion process.
The present invention has the advantages that can be carried out the detection of commutator rosin joint.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of the invention.
Specific embodiment
Below according to the drawings and specific embodiments, the invention will be further described.
As shown in Figure 1, a kind of rotor of the invention and commutator dry joint detection device, including electricity on the platform 1 is arranged
Machine positions fixed mechanism, linkage mechanism and power supply 2, and it includes positioning seat 3 that motor, which positions fixed mechanism, and linkage mechanism includes fixed plate
4, shaft coupling 42 is rotatably fixed with by bearing 41 in fixed plate 4,42 axis of shaft coupling is arranged in left-right direction, fixed plate 4
Front and rear sides are equipped with baffle 43, are vertically and fixedly provided with rotating bar 44 on shaft coupling 42, shaft coupling 42 be rotated in the clockwise direction with
Rotate rotating bar 44 to a baffle side, shaft coupling 42 rotates in the counterclockwise direction so that rotating bar 44 is to another baffle side
Rotation, when motor 5 is placed on positioning seat 3, the output shaft 51 and shaft coupling 42 of motor 5 are coaxial.
Suitable shaft coupling is selected as needed, and existing part may be selected in shaft coupling.Run through when having on the output shaft of motor
Kong Shi may be selected the sleeve with radial hole and be used as shaft coupling, pass through the cooperation realization shaft coupling and output shaft of screws bolts
Linkage；When having biplane construction on output shaft, the shaft coupling with biplane slot may be selected；It is several when having on output shaft
When axially disposed locating slot, the shaft coupling with several axially disposed positioning strips may be selected.
Wherein, 44 vertical welding of rotating bar is fixed on shaft coupling 42, and the length of rotating bar 44 is greater than baffle 43 and shaft coupling
Distance between device 42.Briquetting 31 is equipped on the upside of positioning seat 3, positioning seat 3 is formed with perforative locating slot in left-right direction, briquetting 31
Compression cylinder 32 is collocated with being fixed for motor.Positioning seat of different shapes is selected as needed, when motor is in circle
When column, the V-shaped positioning seat of locating slot may be selected, when motor in a rectangular parallelepiped shape when, the locating slot for the slot that may be selected to be square.
Power supply 2 of the invention is electrically connected with positive direction power change-over switch, and the height of two baffles is below shaft coupling
Highly, so that the rotational angle of rotating bar 44 is greater than 180 °.The positive direction power change-over switch of the present embodiment is integrated in switch enclosure
In 21, switch enclosure 21 has a master switch 211 for cutting off with being connected to power supply, switch enclosure 21 also have make respectively motor main story or
Two forward-reverse switches 212 of reversion.Selection positive direction power change-over switch as needed, mountable two plug-in strips are by cutting
The mode of plug-in strip is changed to change the positive and negative rotation of motor, the control of positive and negative rotation can also be carried out by PLC, single-chip microcontroller etc..The present embodiment
The purpose that forward and reverse power change-over switch is arranged is: facilitating the positive and negative rotation of motor to switch, to improve detection efficiency.
Carry out apparatus of the present invention in use, being placed on positioning seat and carrying out matching for output shaft and shaft coupling for motor
It closes, then carries out the connection of motor power-supply wire and power supply, detection workman keeps the vertically arranged of rotating bar with hand, then presses total
Switch and a forward-reverse switch carry out pressing for another forward-reverse switch after crossing one liang.If rotating bar is acted in rotor
Lower edge rotation, then illustrate the non-rosin joint of commutator.
If commutator rosin joint, due to not being able to maintain equilbrium position, rotating bar meeting under the action of magnet steel and rotor windings
The effect not stressed immediately；If commutator welding is reliable, by Ampere's law it is found that rotor can be always in a state of stress, mirror
This judge commutator whether rosin joint.
The present invention has the advantages that can be carried out the detection of commutator rosin joint.
