Description
Technical field
The present invention relates to motors to assemble field, particularly, is related to a kind of leveling machine assembled for motor stator and rotor
Structure.
Background technique
Large and middle size motor is wide in variety, and batch is few, and product variations are big, before stator assembling, rotor assembling and general assembly all also
It is to continue to use old technique and tooling, is all made of platform position formula assembly method, assembling process is manual operation.The degree of automation is very
Low, assembly period is long, and labor intensity of workers is big, and assembly area is big, and inefficient, assembling quality is unstable, and easily causes various
Injury.
CN 102810949A discloses the assembly machine of a kind of large and middle size motor stator and rotor, including girder and sliding are set
It is placed in main ram on girder, secondary ram, central detection device is set on main ram, in entire rotor suit sub-process,
Circle center in stator is detected by central detection device, base center is adjusted by three-way adjustment device, is led to
It overregulates slip ring end breaket and inputs the center of the height adjustment rotor of end breaket, to realize the detection pair of stator and rotor
In.But the adjustment platform that the document is not related to it is specifically introduced.
CN 202713088U discloses a kind of three layers of alignment platform, including lower layer's high-low regulating, middle layer displacement
Adjust device, upper layer swings adjustment device；The linear guide of middle layer displacement adjusting device is located under lower layer's high-low regulating
On square chest in plane, the displacement square chest of middle layer displacement adjusting device is supported in the lower section of lower layer's high-low regulating by connection leg
The surface of case；The mounting base of upper layer oscillation adjuster is located on pedestal, and the swing square chest of upper layer oscillation adjuster passes through
Second connection leg is supported in the surface of the displacement square chest of middle layer displacement adjusting device.
Wherein, lower layer's high-low regulating is the movement for adjusting short transverse, i.e. adjustment motor stator and rotor axis
Height tolerance.It relies primarily on two pairs of cam mechanisms to adjust, and an axis is driven by motor in each pair of cam mechanism, has two above axis
A cam mechanism., the range very little of cam adjustment but there are deficiencies below for lower layer's high-low regulating: 1), generally existing
Within 20mm, when the high motor in different centers is replaced when using the equipment, need to increase and decrease cushion block to adjust center
It is high；2) requirement when, installing to installer is high, and installation is complicated.It needs to guarantee in a drive shaft when installation
Two cams are identical relative to the position of driving, to guarantee high-low regulating stability and precision；3), machined piece is more,
Such as cam processing is complicated, and trouble is replaced after abrasion, influences to produce.
Middle layer displacement adjusting device is that the level of the movement for adjusting horizontal direction, i.e. adjustment motor stator and rotor axis is inclined
Difference.By synchronous band connection between its driving motor and deceleration, speed reducer is connected with eccentric cam, eccentric cam and pull rod phase
Connection, pull rod are fixed on displacement adjusting device in middle level, and there are two linear guides in the lower end of middle layer displacement adjusting device, when driving electricity
When machine rotates, the adjustment of horizontal direction position can be realized by eccentric cam and linear guide.But middle layer displacement is adjusted
There are deficiencies below for engagement positions: 1), transmission system it is complicated, power is transmitted to speed reducer, speed reducer general by synchronous belt by motor
Power is transmitted to eccentric cam, and eccentric cam drives pull rod, and pull rod drives the movement of horizontal direction；2) precision, adjusted is low, due to
Traditional chain length and complexity, machined piece is more, and precision is low when adjustment, needs compressed spring and friction block to adjust its essence
Degree.Friction block is needed to be replaced frequently as vulnerable part, influences the normal use of equipment.
Upper layer oscillation adjuster is the rotation for adjusting horizontal direction, i.e. adjustment motor stator is parallel with rotor axis.
By synchronous band connection between its driving motor and deceleration, speed reducer is connected with eccentric cam, and eccentric cam is connected with pull rod
It connects, pull rod, which is fixed on, to be swung on square chest, and the center for swinging square chest is equipped with swinging axle, and can rotate around swinging axle, and lower part is equipped with
Second connection leg of compressed spring and friction block swings square chest and is adjusted by pull rod, eccentric cam.But the upper layer, which is swung, adjusts
There are deficiencies below for regulating device: 1), transmission system it is complicated, power is transmitted to speed reducer, speed reducer general by synchronous belt by motor
Power is transmitted to eccentric cam, and eccentric cam drives pull rod, and pull rod drives the movement of horizontal direction；2) precision, adjusted is low, due to
Traditional chain length and complexity, machined piece is more, and precision is low when adjustment, needs compressed spring and friction block to adjust its essence
Degree.Friction block is needed to be replaced frequently as vulnerable part, influences the normal use of equipment.
In addition, the drive part of upper layer oscillation adjuster and middle layer displacement adjusting device is respectively positioned on adjustment main platform body knot
The outer end of structure, topology layout is too fat to move, not compact, and occupied space influences beauty.Since lower layer's high-low regulating uses cam tune
Whole, adjustable range is small, when the motor with pallet enters adjustment platform, first passes through raceway system and enters decline raceway system
System, decline raceway system decline certain height again and the motor stator with pallet are placed on adjustment platform.The decline raceway
System is divided into the two groups of descending mechanisms in left and right, and lifting is realized by two sets of hydraulic systems, need to guarantee that two groups of left and right descending mechanism is synchronous.
It is asynchronous to which the case where raceway system is damaged, and hydraulic system will be declined to occur two groups of hydraulic systems during use
In the presence of leakage hydraulic oil, the problems such as inconvenient is safeguarded.
As the above analysis, although the centering adjustment of motor stator and rotor may be implemented in existing levelling mechanism, but
The problems such as that there are still adjustable ranges is small, degree of regulation is low, machined piece is more, production installation is complicated, at high cost and deficiency.Therefore it needs
Design a kind of novel motor assembly levelling mechanism.
