Definitions
- the present invention relates to a wrist mechanism provided at the tip of an arm of an articulated robot.
- the arm of the articulated robot is, for example, the first 1 ⁇ 23 ⁇ 4j, as shown in Fig. 2, as shown in Fig. 2.
- the rain that extends in the longitudinal direction of the arm 1 at 53 ⁇ 43 ⁇ 4IJ of the hollow arm 1 is perpendicular to the j-axis R »axis B
- the hand 2 is provided with an end effector 3 that can move about a rotation axis ⁇ that traverses the rotation axis B. L, ru.
- the arm 1 has a «tJ suspension, and a mounting seat 1 1 is provided for attaching the fixing 4 1 of the arm 4, and the input shaft 4 2 of the speed reducer 4 is protruded into the arm 1.
- the drive / motor 5 is fixed parallel to the longitudinal direction of the arm 1, the output shaft 51 is arranged parallel to the rotation axis R, and the output shaft 5 of the vertical motor 5 1 is connected via bevel gears 43, 52 to make the power be increased.
- the output shaft 4 of the reducer projects out of the arm 1 to fix the wrist 2.
- the wrist part 2 is offset from the rotation axis R and has an output shaft 61 extending along an Ir 'working axis perpendicular to the force rotation axis B. 1 is fixed to the end effector and 3 is fixed.
- «6 is the motor 73 ⁇ 43 ⁇ 4: The one that is combined is disclosed (for example, Japan Real Kaihei No. 1-129900, U actual opening 2-10 7 4 8 1).
- ⁇ ⁇ a first hand that can rotate around the rotation axis R while being at a predetermined angle with respect to the rotation axis R extending in the longitudinal direction of the arm 1.
- ⁇ 2 0 1 and the first hand 2 0 1 ⁇ 3 ⁇ 4 ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ 2 ⁇ ⁇ ⁇ ⁇ ⁇ It is disclosed that a male member 203 is provided around a rotation axis ⁇ orthogonal to the rotation axis ⁇ (see, for example, Japanese Patent Application Laid-Open No. 62-5464). 9 2).
- the hand decoration 2 is offset with respect to the rotation axis R, so that it becomes a computational power type for the 3 ⁇ 4 ⁇ 3 ⁇ 4 inferior 3 who is fixed to -2.
- the ship's drip titer would be used.
- the arm 1 is fitted with S3 duck overnight 4 and 5 dedicated to the second capital 202 and 2f temple ⁇ 3, and the motors 4 and 5 are included in the first 3 ⁇ 43 ⁇ 4201.
- the power is applied to the second action of the force field
- an object of the present invention is to provide a wrist finely designed for a multi-joint robot that has no wrist offset, has high strength and high rigidity, and is simple to configure.
- the present invention provides an arm capable of one force and a rotation axis B perpendicular to a rotation axis R extending in the longitudinal direction of the self-arm at a distance from the B d arm.
- the wrist part is provided so that it can be snarled, and the front part of the hand is provided with a pivot that rotates about a rotation axis T that is orthogonal to the circulation rotation axis B.
- the knitting arm is tilted with respect to the longitudinal direction of the arm.
- the angled arm, and ii on the side facing the self-rotating axis R ⁇ in drawing is provided with a mounting seat of 1 m above the [ ⁇ force axis R]
- a drive unit for driving the hand 1 is fixed inside the oblique arm along the oblique direction, and is attached to a mounting seat of a ij motor, The output shaft of the motor and the front input shaft are connected by the combination of two bevel gears.
- FIG. 1 is a side sectional view showing an example of the 'pot invention
- FIG. 3 is a schematic diagram showing a second alternative example.
- FIG. Fig. ⁇ A side sectional view showing a difficult example of Hayashi invention.
- 1 is an arm
- Ml is a hollow that extends in a direction inclined at an acute angle 0 with respect to a rotation axis R that extends in the longitudinal direction of the arm 1 ⁇ 13 ⁇ 4 ⁇ arm 1 01 fixed It has been done.
- the drive motor 5 is fixed to the inside of the inclined arm 101, its output shaft 51 is extended in the longitudinal direction of the inclined arm 101, and the bevel gear 52 is fixed.
- a width-shaped housing 102 is attached, and a mounting seat 103 is provided on the side of the side facing the shaft R of the housing 102, and the ⁇ P4 1 of il ⁇ 4 is provided.
- the bevel gear 43 is fixed so that the input shaft 42 of FIG. 4 protrudes into the housing 102, and engages with the bevel gear 52.
- the output shaft 44 of 4 protrudes out of the housing 102 to fix the hand 2 so that it can rotate around a rotation axis B orthogonal to the rotation axis R.
- the end effector 3 is fixed to the output shaft 6 1 of 6, and the end effector 3 is fixed to 6 (fgfj by the ⁇ motor 7).
- the arm 1 is fixed to the top of the arm 1 with a tilt arm 1 0 1 ⁇ 1, and a hand ⁇ 2 is provided in a direction facing the driving axis R in the longitudinal direction of the arm 1.
- the wrist 2 is arranged on the rotation axis R-H when it is turned, so that the capital 2 should have no offset with respect to the rotation axis R. Wear.
- the 13 ⁇ 4 inclined arm 101 is fixed to the arm 1 and the hand ⁇ 2 is fixed to the other side of the ⁇ motor. Since it is fixed directly to 2, the distance between the Okimo Ichiyu and the one-year-old is short, and there is no car that generates power and I power.
- the hand portion is formed so as not to be offset in the ⁇ ⁇ ⁇ ⁇ ⁇ direction of the arm. Since the distance between the motor and the motor is shortened, it is possible to easily control the end effector if necessary, increase power and rigidity, and simplify the structure. There. ,
- the present invention is useful for industrial robots, in particular, for dispersing hands of an articulated robot.
