A kind of governor motion of AGV trolley driving mechanismTechnical field
The present invention relates to AGV technical field, particularly to the governor motion of a kind of AGV trolley driving mechanism.
Background technology
AGV has had the history of more than 50 year from invention, and along with the extension of application, its kind and form become manyPlant various.At present, the walking mechanism that AGV generally uses is the four-wheel walking mechanism of band steering wheel, and this walking mechanism includes two rowWalk driving wheel, two support wheels and be distributed with rhombus.Four-wheel walking mechanism with steering wheel is to show on three-wheel walking mechanism basisChange comes, and it is equivalent to two tricycles to combine, and two bogie wheels are symmetrically arranged on the center line after Plantago minuta,Front and back wheel is respectively symmetrically the isosceles triangle apex being arranged in two bogie wheel fulcrums as base.Front and back wheel is steering wheelIt it is again running wheel.This AGV dolly is front and back wheel all energy track homing line trackings when turning, and mobility compares tricycleGood.But, this walking mechanism there is also problems with: this walking mechanism AGV is not suitable for doing the original place rotation of intensive storage AGVTranshipment: when car body rotates in place, takes turns due to the support on both sides and does not has driving force, and its motility rotated and smoothness are the most notEnough.
Summary of the invention
The technical problem to be solved is to provide the governor motion of a kind of AGV trolley driving mechanism, reasonable in design,Turn to flexible and stable performance, to solve the above-mentioned multinomial defect caused in prior art.
For achieving the above object, the present invention provides following technical scheme: the regulation machine of a kind of AGV trolley driving mechanismStructure, including drive mechanism base and the fixed plate being arranged on drive mechanism base two ends, fixed plate is provided with drive mechanism, describedBeing provided with governor motion at drive mechanism, described drive mechanism includes drive shaft, driving wheel and motor, and motor is arranged on fixed plateOn, driving wheel is arranged on the end of drive shaft, and both relatively rotate connection, and the two ends of drive mechanism base are provided with cavity, driveDynamic main shaft is arranged in cavity, and cavity open-mouth is provided with main shaft baffle plate, is connected by chain assemblies between driving wheel and motor；Described fixed plate is provided with at least two parallel grooves, and described motor is provided with motor fixing seat, bolt through parallel groove withMotor fixing seat bolt connects；Described governor motion includes motor pressing plate and motor top board, and motor pressing plate is arranged on fixed plateOuter end, motor top board arranges between motor and drive mechanism base, and motor top board is fixing relative to fixed plate to be connected, motor pressurePlate is provided with the bolt depression bar contacted with motor fixing seat, is provided with spacing mandril and top between motor top board and motor fixing seatSpring guide rod, spacing mandril and top spring guide rod are arranged on motor top board, and top spring leader casing is connected to limit spring, limit spring and electricityMachine is fixed seat and is contacted.
Preferably, the end of described motor top board is provided with Limit Bearing, and Limit Bearing contacts with drive mechanism base.
Above technical scheme is used to provide the benefit that: the governor motion of the AGV trolley driving mechanism of present configuration, bagInclude two independent drive mechanisms, the method being possible not only to reduce two wheel distances, will be decomposed into apart from two remote wheel differentialsApart from the differential of some groups of little two wheels, fundamentally solve Vehicular turn speed issue and vehicle two wheel distance RValue minimization problem.

Detailed description of the invention
Describe the preferred embodiment of the present invention below in conjunction with the accompanying drawings in detail.
Fig. 1 shows the detailed description of the invention of the present invention: the governor motion of a kind of AGV trolley driving mechanism, including driving machineStructure base 1 and the fixed plate 2 being arranged on drive mechanism base 1 two ends, fixed plate 2 is provided with drive mechanism, described drive mechanismPlace is provided with governor motion, and described drive mechanism includes drive shaft 3, driving wheel 4 and motor 5, and motor 5 is arranged in fixed plate 2,Driving wheel 4 is arranged on the end of drive shaft 3, and both relatively rotate connection, and the two ends of drive mechanism base 1 are provided with cavity, driveDynamic main shaft 3 is arranged in cavity, and cavity open-mouth is provided with main shaft baffle plate 6, by chain assemblies 7 phase between driving wheel 4 and motor 5Connect；Described fixed plate 2 is provided with at least two parallel grooves 8, and described motor 5 is provided with motor fixing seat 9, and bolt is through flatRow chute 8 is connected with motor fixing seat 9 bolt；Described governor motion includes motor pressing plate 10 and motor pressing plate 11, motor pressing plate10 outer ends being arranged on fixed plate 2, motor pressing plate 11 arranges between motor 5 and drive mechanism base 1, and motor pressing plate 11 is relativeIn the fixing connection of fixed plate 2, motor pressing plate 10 is provided with the bolt depression bar 12 contacted with motor fixing seat 9, motor pressing plate 11And it is provided with spacing mandril 13 and top spring guide rod 14, spacing mandril 13 and top spring guide rod 14 between motor fixing seat 9 and is arranged on motorOn pressing plate 11, top spring guide rod 14 is socketed with limit spring 15, and limit spring 15 contacts with motor fixing seat 9.
As the further improved procedure of the present invention, it is provided with Limit Bearing 16, limit shaft in the end of motor pressing plate 11Hold 16 to contact with drive mechanism base 1.
To sum up, by the governor motion of AGV trolley driving mechanism on AGV car body, make AGV dolly can as tradition unidirectionalAGV is the same smoothly to walk, and the power of same loading capacity AGV unidirectional with tradition required motor is the same, and required motor power is low, jointCost-saving, and owing to can control dolly shake double-direction turning movement by controlling the rotating speed of four motors, dolly is operationally without certainlyBody rotates in place, and can reduce track and take up room, and is suitable for working in intensive storage.
Above is only the preferred embodiment of the present invention, it is noted that for the person of ordinary skill of the art,Without departing from the concept of the premise of the invention, it is also possible to make some deformation and improvement, these broadly fall into the guarantor of the present inventionProtect scope.
