Description
Technical field
This utility model relates to a kind of horizontal articulated robot, particularly relates to a kind of horizontal articulated robot wrist
Rotate shaft drive.
Background technology
Existing level articulated robot the 4th axle is wrist rotary shaft, and its kind of drive many employings planetary reducer adds same
The kind of drive of step band or the independent kind of drive using harmonic wave speed reducing machine.Relatively big due to speed reducing ratio with upper type, cause hands
Wrist rotary shaft rotating speed is relatively slow, affects mass motion beat, and reductor needs regular grease up, adds maintenance work
Amount, which is relatively costly.
Utility model content
The purpose of this utility model is to solve in prior art the defect existing for wrist transmission of rotary axis mode, carrying
Shaft drive is rotated for a kind of horizontal articulated robot wrist.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of horizontal articulated robot wrist rotates shaft drive, including base, base is provided with underarm with
And the upper arm being connected with underarm, described upper arm is fixed with motor, the lower section of upper arm be provided with wrist flange and with wrist flange
The splined shaft connected, splined shaft is connected by drive mechanism with described motor.
The horizontal articulated robot wrist of above-mentioned one rotates shaft drive, and described drive mechanism includes and motor
Output shaft connect the first belt wheel, be positioned at the second belt wheel of described upper arm, threeth belt wheel coaxially connected with the second belt wheel
And be set in the 4th belt wheel outside described splined shaft, described first belt wheel and the second belt wheel and connected by the first belt, the
Three belt wheels and the 4th belt wheel are connected by the second belt.
The horizontal articulated robot wrist of above-mentioned one rotates shaft drive, and the outer sheath of described splined shaft is provided with
Power transmission shaft and spline are female, and power transmission shaft is connected with described 4th belt wheel.
The horizontal articulated robot wrist of above-mentioned one rotates shaft drive, and described wrist flange is also associated with hands
Wrist rotary shaft.
The beneficial effects of the utility model are: use two-stage toothed belt transmission to realize the rotation of wrist rotary shaft, can make
Gear ratio reaches 10～25, both ensure that enough wrist moments of torsion, and had also improved the rotating speed of wrist rotary shaft, additionally this transmission side
Formula, also without lubrication, decreases maintenance workload.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model；
Fig. 2 is the schematic diagram of this utility model drive mechanism.
Detailed description of the invention
As shown in Figure 1 and Figure 2, a kind of horizontal articulated robot wrist rotates shaft drive, including base 1, the end of at
Seat 1 is provided with underarm 2 and the upper arm 3 being connected with underarm 2, and upper arm 3 is fixed with motor 4, and the lower section of upper arm 3 is provided with wrist method
Blue 5 and the splined shaft 6 that is connected with wrist flange 5, splined shaft 6 is connected by drive mechanism with motor 4, drive mechanism include and
The first belt wheel 7 that the output shaft of motor 4 connects, is positioned at the second belt wheel 8 of upper arm 3, threeth coaxially connected with the second belt wheel 8
Belt wheel 9 and be set in the 4th belt wheel 10 outside splined shaft 6, the first belt wheel 7 and the second belt wheel 8 are by the first belt 11 even
Connecing, the 3rd belt wheel 9 and the 4th belt wheel 10 are connected by the second belt 12.
The outer sheath of splined shaft 6 is provided with power transmission shaft 13 and spline mother 14, and power transmission shaft 13 is connected with the 4th belt wheel 10, wrist method
Blue 5 are also associated with wrist rotary shaft.
After motor 4 axle rotates, drive the first belt wheel 7 to rotate, and drive the second belt wheel 8 and the 3rd band by the first belt 11
Wheel 9 rotation, the 3rd belt wheel 9 drives the 4th belt wheel 10, power transmission shaft 13 and spline female 14 to rotate by the second belt 12, and spline is female
14 and then drive splined shaft 6 and wrist flange 5 to rotate.
This device uses two-stage toothed belt transmission to realize the rotation of wrist rotary shaft, and gear ratio can be made to reach 10～25,
Both ensure that enough wrist moments of torsion, and also improved the rotating speed of wrist rotary shaft, additionally this kind of drive is also without lubrication, subtracts
Lack maintenance workload.
This utility model is not limited to above-mentioned preferred forms, and anyone can draw under enlightenment of the present utility model
Other various forms of products, no matter but in its shape or structure, make any change, every have same as the present application or phase
The technical scheme of approximation, within all falling within protection domain of the present utility model.
