Description
Technical field
It the utility model is related to mechanical field, and in particular to rack pinion lever type mechanical hand.
Background technology
Manipulator is a kind of some holding functions that can imitate human hand and arm, to be captured by fixed routine, carry object
Or the automatic pilot of operation instrument.Manipulator is the industrial robot occurred earliest, and the modern machines occurred earliest
People, it can replace the heavy labor of people to be operated to realize the mechanization of production and automation under hostile environment to protect people
Body safety, thus it is widely used in the departments such as machine-building, metallurgy, electronics, light industry and atomic energy.In in life, section now
Skill day crescent benefit progress under, robot and the maximum difference of arm for having the mankind are that flexibility ratio and resistance to dynamics.
Be exactly manipulator sharpest edges it is recursive do it is same action machinery will not always feel tired under normal circumstances.Machinery
The application of arm also will be more and more extensive, and manipulator is a kind of high-tech automatic producing device that recent decades grow up,
The ability to be fulfiled assignment in the accuracy and environment of operation.Wherein, rack pinion lever type mechanical hand of the prior art be by
The two-sided rack is made in drive rod end, is engaged with the sectional wheel of both sides, and sectional wheel is fixed together with finger, is turned round around fulcrum,
Driving force promotes rack to make straight reciprocating motion, you can elevating arc revolution is driven, so that finger unclamps or closure, due to driving
The motion for the linear reciprocation that bar uses drives release or the closure of finger, and the space shared by drive rod is longer, but is producing
In life, the movable space of its drive rod is restricted, and the drive rod of prior art is unsatisfactory for condition.
Utility model content
Technical problem to be solved in the utility model is that the drive rod driving of the rack pinion manipulator of prior art needs
Larger space is wanted, and it is an object of the present invention to provide rack pinion lever type mechanical hand, changes traditional rack pinion structure, reduces driving
Space used.
The utility model is achieved through the following technical solutions：
Rack pinion lever type mechanical hand, including power rail, housing, driven gear, fixing axle, the power rail are set vertically
Put；The housing upper is in solid cylinder, and bottom is connected on the downside of solid cylinder vertically by two pieces of parallel planar structures；It is described dynamic
Power bar passes vertically through solid cylinder, and the power rail is with solid cylinder by setting power rail installation to be threadedly coupled；It is described driven
Gear has two, between being arranged on the two boards shape structure of housing by fixing axle, and is respectively at power rail both sides；It is described
The surface that power rail is between the two boards shape structure of housing is provided with power rail driving screw thread, and the power rail drives screw thread
It is engaged with the driven gear of both sides；The lines of power rail installation screw thread and power rail the driving screw thread has folder with horizontal plane
Angle, the lines of the driven gear and the axis of driven gear are not parallel；Set respectively on through two fixing axles of driven gear
Symmetrical actuating arm is equipped with, symmetrical finger is provided with the downside of actuating arm.
Rack-gear type manipulator of the prior art makees the folding of the reciprocating motion control finger of straight line by drive rod,
This mode needs to reserve the space of motion for drive rod, although its space is long and narrow, in the production process of reality,
Also other equipment can be caused to hinder, or the delay of its space is unreasonable, causes the waste in space.The utility model is in power rail
Upside set power rail install screw thread be connected with housing, power rail rely on power rail install screw thread rotated on housing, due to
Power rail installation screw thread is formed an angle with horizontal plane shape, and power rail can be declined or be lifted while rotating, and according to
The power rail that is screwed is installed by power rail, power rail is not glided；Set on the downside of power rail power rail drive screw thread with from
Moving gear is engaged, because power rail driving screw thread and horizontal plane form certain angle, and the lines and driven gear of driven gear
Axis it is not parallel, power rail can drive driven gear to be rotated when rising or falling, when power rail rises
Waiting driven gear drives actuating arm and finger to be closed, when power rail declines driven gear drive actuating arm and
Finger opens, and thus achieves the gripping function of manipulator.Wherein, due to use pinion rotation be driven, its rotate rise or
Mechanical arm and finger closure can just be caused or open larger angle by declining shorter distance, so as to solve in the prior art
The problem of existing.
Further, two vertical planes of driven gear are provided with misaligned groove.
Further, two actuating arms are each provided with from fixing axle, it is vertical that two actuating arms are arranged on driven gear
The both sides in face.
Further, the finger that the actuating arm in two driven gear the same sides is connected is matching；Wherein side
Finger be mechanical right angle finger, the finger of opposite side is mechanical arc finger.
In the both sides of driven gear, that is, the both ends of fixing axle respectively set an actuating arm and a finger, can be with
Realize the gripping function of different size objects, mechanical right angle finger can grip the object of reduced size, and mechanical arc finger
The object of large-size can be gripped.When the work of mechanical right angle finger is needed, by driven gear to connecting mechanical right angle
The actuating arm of finger is stirred, and allows the actuating arm clamp of the side in the groove of this side of driven gear, and such driven gear rotates
When just can drive carry mechanical right angle finger actuating arm rotation, so as to realize the opening and closure of mechanical right angle finger；
When the work of mechanical arc finger is needed, driven gear is stirred to the actuating arm for connecting mechanical arc finger, allows the side
Actuating arm clamp can just be driven in the groove of this side of driven gear, when such driven gear rotates and carry mechanical arc
The actuating arm of shape finger rotates, so as to realize the opening of mechanical arc finger and closure.
Further, the diameter of power rail be 3 times of the thickness of driven gear and more than.Due to power rail and driven gear
Position can change, therefore the thickness for the ratio driven gear that the diameter of power rail is set is thicker, is easy to strengthen driven tooth
Wheel and being engaged between power rail, strengthen the controling power of finger.
The utility model compared with prior art, has the following advantages and advantages：
1st, the utility model replaces linear re-ciprocating motion using pinion rotation transmission, and its rotation rises or falls shorter
Distance can just cause mechanical arm and finger to close or open larger angle, reduce drive rod or power rail occupied
Space；
2nd, the utility model sets two sets of different fingers on driven gear, meets wanting for gripping size different objects
Ask, improve practical degree.
