Description
Technical field
This utility model relates to a kind of horizontal articulated robot, particularly relates to a kind of horizontal articulated robot straight line
The brake unit of axle.
Background technology
Existing level articulated robot the 3rd axle is linear axis, and is positioned at vertical direction.Without brake measure, machine
After device people's power-off, this linear axis, in action of gravity, has the trend moved downward, and may bump against body or peripheral equipment, cause
Infringement.Join brake for this this linear axis servomotor multiselect, but the motor open market of band brake uses less, and valency
Lattice are expensive a lot, and additionally brake is easily worn part, once damages, and need to change whole motor, and maintenance workload is big, and cost
High.
Utility model content
The purpose of this utility model is existing in order to solve horizontal articulated robot linear axis braking in prior art
Defect, it is provided that the brake unit of a kind of horizontal articulated robot linear axis.
To achieve these goals, the technical solution adopted in the utility model is:
The brake unit of a kind of horizontal articulated robot linear axis, including base, is provided with on base and can relatively rotate
Underarm and upper arm, on described upper arm connect have lead screw shaft, the sheathed nut in top of lead screw shaft, described lead screw shaft is away from described spiral shell
Female one end is provided with arrestment mechanism, and the top of described upper arm is provided with motor by motor mount, and motor passes through drive mechanism
It is connected with the middle part of described lead screw shaft.
The brake unit of above-mentioned a kind of horizontal articulated robot linear axis, described drive mechanism includes being fixed on described
First belt wheel of the output shaft end of motor, is set in outside described lead screw shaft and fixes the second belt wheel being connected with lead screw shaft,
First belt wheel and the second belt wheel are connected by belt.
The brake unit of above-mentioned a kind of horizontal articulated robot linear axis, described arrestment mechanism includes being fixed on described
The brake rotor of lead screw shaft end, is set in outside brake rotor and is fixed on the brake stator on the downside of described upper arm.
The brake unit of above-mentioned a kind of horizontal articulated robot linear axis, described brake rotor passes through holding screw
Being fixed in lead screw shaft, brake stator is arranged on upper arm by hexagon socket cap head screw.
The brake unit of above-mentioned a kind of horizontal articulated robot linear axis, described brake stator and brake rotor
Outside be provided with the sealing shroud being connected with described upper arm.
The brake unit of above-mentioned a kind of horizontal articulated robot linear axis, described nut connects wrist flange.
The beneficial effects of the utility model are: brake and the motor of this device are provided separately, by driven by motor leading screw
Axle rotates, and arrestment mechanism is positioned at the end of lead screw shaft and uses external band-type brake to realize the braking of linear axis, not only reduces cost,
And be easy to safeguard.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model；
Fig. 2 is the A district enlarged drawing in Fig. 1；
Fig. 3 is the B district enlarged drawing in Fig. 1.
Detailed description of the invention
As shown in Figure 1 to Figure 3, the brake unit of a kind of horizontal articulated robot linear axis, including base 1, at base 1
Being provided with relatively turnable underarm 2 and upper arm 3, upper arm 3 connects lead screw shaft 4, the sheathed nut in top 5 of lead screw shaft 4, spiral shell
Female 8 connect wrist flange 9, and lead screw shaft 4 is provided with arrestment mechanism 6 away from one end of nut 5, and the top of upper arm 3 is installed by motor
Seat is provided with motor 7, and motor 7 is connected with the middle part of lead screw shaft 4 by drive mechanism 8.
Drive mechanism 8 includes the first belt wheel 81 being fixed on the output shaft end of motor 7, be set in outside lead screw shaft 4 and
Second belt wheel 82 that be connected fixing with lead screw shaft 4, the first belt wheel 81 and the second belt wheel 82 are connected by belt 83.
Arrestment mechanism 6 includes the brake rotor 61 being fixed on lead screw shaft 4 end, be set in outside brake rotor 61 and
Being fixed on the brake stator 62 on the downside of upper arm 3, brake rotor 61 is fixed in lead screw shaft 4 by holding screw 63, braking
Device stator 62 is arranged on upper arm 3 by hexagon socket cap head screw 64, brake stator 62 and the outside of brake rotor 61
It is provided with the sealing shroud 65 being connected with upper arm 3.
When powering up, owing to not producing holding torque between brake rotor 61 and brake stator 62, after motor shaft rotates,
Drive the first belt wheel 81 to rotate, and drive the second belt wheel 82 and lead screw shaft 4 to rotate by belt 83, during power-off, brake stator
62 pairs of brake rotors 61 produce holding torque, make lead screw shaft 4 not rotate, thus prevent nut 5 to slide under gravity,
If mechanical hand is in use, brake assembly is damaged, and can directly change brake, need not dismantle and change motor
7, the design of above structure, by using external band-type brake to realize the braking of linear axis, not only reduces cost, and is easy to safeguard.
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.
