The rotation of rotating mechanical arm, gearratio Z3:Z4=1:2;3rd group:The rotation of telescopic mechanical arm is converted to end mechanical arm
Rotation, gearratio Z5:Z6=2:1;4th group:The rotation for being converted to end effector of end mechanical arm, pass
Dynamic ratio is Z7:Z8=1:2;5th group:The rotation for being converted to screw mandrel of the second stepper motor, gearratio Z9:Z10=4:
5;6th, 7 group:The rotation for being converted to driving wheel of direct current drive arbor.Reducing gear, for realize reduce first with
And second stepper motor output shaft speed and increase motor driving moment.Lead screw guide rails mechanism, silk is driven by the rotation of screw mandrel
Stem nut moves up and down along screw mandrel so that lifting platform drives elevation and subsidence mechanical arm to move up and down.Lifting platform, elevation and subsidence mechanical arm, stretch
Contracting mechanical arm, rotating mechanical arm and end mechanical arm, elevation and subsidence mechanical arm drive end effector to lift in vertical plane
Motion;Rotating mechanical arm drives end effector to rotate in the horizontal plane;Pass through the 5th synchronous pulley, the 6th synchronous pulley,
The transmission of seven synchronous pulleys, the 8th synchronous pulley and end mechanical arm motion, telescopic mechanical arm will drive end effector to make
Horizontal rectilinear motion.
Further, walk in the present embodiment, three freedom degree manipulator control method is as follows:
Stretching motion is driven:5th synchronous pulley 14 is fixed in elevation and subsidence mechanical arm 24, is stretched when the 3rd stepper motor 5 drives
When mechanical arm 26 rotates, the 6th synchronous pulley 15 will form revolution relative to elevation and subsidence mechanical arm 24 and autobiography, due to end machine
Tool arm 27 is fixed in the 6th synchronous pulley 15, and then end mechanical arm 27 is synchronous with the rotation of the 6th synchronous pulley 15 turns
Dynamic, then end mechanical arm 27 rotates 26, and direction of rotation and the OQ t machine of telescopic mechanical arm 26 relative to telescopic mechanical arm
The direction of rotation of tool arm 24 is on the contrary, corner value is 2 times of the corner of telescopic mechanical arm 26(5th synchronous pulley 5 and the 6th timing belt
The gear ratio of wheel is Z5:Z6=2:1).7th synchronous pulley 16 is fixed in telescopic mechanical arm 26, when end mechanical arm 27 is relative
When telescopic mechanical arm 26 rotates, the 8th synchronous pulley 17 will form revolution relative to telescopic mechanical arm 26 and autobiography, due to end
End actuator 25 is fixed in the 8th synchronous pulley 17, then the opposing end portions mechanical arm 27 of end effector 25 rotates, and rotation side
To the direction of rotation with the relative telescopic mechanical arm 26 of end mechanical arm 27 on the contrary, corner value is the corner of end mechanical arm 27
1/2(The gear ratio of 7th synchronous pulley and the 8th belt wheel is Z7:Z8=1:2).According to the calculating of corner vector sum, end performs
The corner of the OQ t mechanical arm 24 of device 25For telescopic arm angle, end mechanical arm angleAnd end effector
CornerVector, therefore when the 3rd stepper motor 5 drives flexible machinery through the second decelerator 7
When arm 26 rotates, end effector does not rotate relative to elevation and subsidence mechanical arm all the time, only moves linearly.That is the 3rd stepper motor passes through
The intermediate transmission mechanisms such as the second decelerator, telescopic mechanical arm, end mechanical arm, two groups of toothed belt transmissions driving end effector
Make horizontal rectilinear motion.
Rotary motion is driven mechanism:First stepper motor 3 passes through the first synchronous pulley, the second synchronization through the first decelerator 6
Drive guide rail 18 to rotate, because the 3rd synchronous pulley 12 can not rotate around guide rail 18, but can be moved up and down along guide rail 18, therefore
3rd synchronous pulley 12 and guide rail synchronous axial system, the transmission through the 4th synchronous pulley 13 so as to drive rotating mechanical arm 24 to rotate,
That is the first stepper motor is through the first decelerator, the first synchronous pulley, the second synchronous pulley, the 3rd synchronous pulley, the 4th timing belt
The intermediate transmission mechanisms such as wheel driving rotating mechanical arm rotates.
Elevating movement is driven mechanism:Second stepper motor 4 is driven by the transmission of the 9th synchronous pulley, the tenth synchronous pulley
Screw mandrel 19 rotates, so as to which drive screw nut 22 moves up and down along screw mandrel, because lifting platform 20 and feed screw nut 22 are connected, therefore
Lifting platform 20 synchronously moves up and down with feed screw nut 22, so as to drive elevation and subsidence mechanical arm 24 to lift, that is, walks the second stepper motor through
The intermediate transmission mechanisms such as nine synchronous pulleys, the tenth synchronous pulley, leading screw, lifting platform driving elevation and subsidence mechanical arm makees elevating movement.
In summary, above three moves, and linear motion, rotary motion, elevating movement, cooperates cooperation so that three
Free degree manipulator end effector can complete transport operation in certain space.
Lorry structural principle:Dolly vehicle body uses four-wheel car body, coordinates aluminium alloy to have light, hard as vehicle frame
Gu the features such as.Whole vehicle body movement aids in the mobile configuration mode of front-wheel drive using trailing wheel:Two-wheeled is as two before vehicle body
Independent driving wheel, pass through the 11st synchronous pulley, the 12nd synchronous pulley, the tenth by two high pulling torque dc motors respectively
Three synchronous pulleys, the 14th synchronous pulley driving mechanism are operated alone, and the direction of motion of vehicle body is controlled using their speed discrepancy;
And trailing wheel is then two universal wheels, they play a part of supporting vehicle body as supporting roller.This configuration mode is simple in construction,
It is easily controllable, and when two driving wheel constant speed, rotate backward when, vehicle body can only around the midpoint of the two driving wheel lines from
Turn, be easy to position and commutate.
Driving wheel and universal wheel, it is respectively installed in the front and back end of robot bottom plate.Driving wheel is by high pulling torque direct current drive
Machine drives;Universal wheel coordinates driving wheel band mobile robot to move as supporting roller.Two groups of synchronous belt drive mechanisms, including
Synchronous pulley 11,12,13,14 and supporting timing belt, every group of synchronous belt mechanism export each self-corresponding dc motor
Power passes to corresponding driving wheel, so as to drive whole robot to move.Described two high pulling torque direct currents with encoder
Motivation, afterbody are equipped with photoelectric encoder, and resolution ratio is 334 lines, and motor supply voltage is 24V, rated moment 6N.m, and maximum turns
Scooter 200rpm, meet robot system design requirement.
Above is preferred embodiment of the present utility model, all changes made according to technical solutions of the utility model are produced
Function without departing from technical solutions of the utility model scope when, belong to the scope of protection of the utility model.
