Description
Technical field
A kind of mechanical suspension arm propeller structure of the utility model, is related to one kind in machinery production, to suspension arm into
The structure of row screw propulsion, belongs to field of machining.In particular to a kind of cooperation by drive ring and clip plate is to suspension
Arm is promoted, and interior swivel nut and outer tube are separated, the push structure not influenced by suspension arm active force.
Background technique
Currently, often use suspension arm in machinery production and carry out the lifting of product, and then carry out carrying promotion etc.,
Existing simple lift structure uses propeller structure, drives screw rod rotation by motor so that swivel nut on screw rod along
Screw rod is axially moved, suspension arm be located at it is vertical with screw rod on swivel nut side wall, when being lifted by crane, suspension arm stress so that
Impact direction between swivel nut and screw rod deflects, and influences the fluency for suspending arm lifting, serious meeting so that bent screws,
It, cannot be when suspending the bending of arm stress especially when suspension arm stress is larger, swivel nut and screw rod are still coaxial.
Summary of the invention
In order to improve above situation, a kind of mechanical suspension arm propeller structure of the utility model provides one kind and passes through drive
The cooperation of rotating ring and clip plate promotes suspension arm, and interior swivel nut and outer tube are separated, not by suspension arm effect
The push structure that power influences.The fluency of suspension arm lifting moving can be effectively improved.
A kind of mechanical suspension arm propeller structure of the utility model is achieved in that the utility model is a kind of mechanical outstanding
Arm propeller structure is set by screw rod, drive ring, outer tube, interior swivel nut, rubber ring, drive sleeve, attachment base, stop collar and internal pressure
Board group is at attachment base is placed on outer tube lateral wall, and transmission is placed on outer sleeve inner wall, and two stop collars are respectively placed in transmission
It covers on inner wall, and respectively close to drive sleeve both ends, multiple L-type cracks, and corresponding crack position is equidistantly provided in the drive sleeve
The inside bending of the part outer tube set forms clip plate, and the transverse crack in the L-type crack and the angle of Vertical Cracks are acute angle,
And transverse crack is arcuate structure, interior swivel nut is placed in drive sleeve, and drive ring is placed on interior swivel nut one end, and with drive sleeve inner wall
On stop collar on the lower fit, the outer diameter of the drive ring is gradually increased from bottom to top, and the clip plate bottom is located at
The top of drive ring, screw rod runs through outer tube, and passes through out of interior swivel nut, the screw rod and interior swivel nut bolt, two rubber
Ring is respectively placed in outer tube both ends, and inner wall fits with screw rod outside respectively.
In use, screw rod one end is connected with external motor first, attachment base is connected with suspension arm then, is lifted by crane
When, external motor drives screw rod rotation, and interior swivel nut and screw rod are spirally connected, and then interior swivel nut is moved along screw rod, interior swivel nut band
Dynamic drive ring is mobile, and drive ring pushes clip plate, and then pushes drive sleeve mobile, and drive sleeve drives outer tube to move along screw rod
It is dynamic, and then outer tube drives suspension arm to carry out by attachment base, realizes lifting movement, during lifting, suspends arm to housing
Pipe applies active force, and since interior swivel nut and outer tube are not directly contacted with, and then interior swivel nut does not stress, and interior swivel nut and screw rod keep perpendicular
Directly, guarantee the mobile fluency of suspension arm, reach in machinery production, the purpose of screw propulsion is carried out to suspension arm.
Beneficial effect.
One, structure is simple, convenient and practical.
Two, cheap, it is easy to spread.
Three, the fluency of suspension arm lifting moving can be effectively improved.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of mechanical suspension arm propeller structure of the utility model.
Fig. 2 is a kind of three-dimensional structure diagram of mechanical suspension arm screw propulsion knot drive sleeve of the utility model.
In attached drawing
Wherein part are as follows: screw rod (1), drive ring (2), outer tube (3), interior swivel nut (4), rubber ring (5), drive sleeve (6),
Attachment base (7), stop collar (8), clip plate (9).
Specific embodiment:
A kind of mechanical suspension arm propeller structure of the utility model be achieved in that by screw rod (1), drive ring (2),
Outer tube (3), interior swivel nut (4), rubber ring (5), drive sleeve (6), attachment base (7), stop collar (8) and clip plate (9) composition, even
Joint chair (7) is placed on outer tube (3) lateral wall, and drive sleeve (6) is placed on outer tube (3) inner wall, and two stop collars (8) are set respectively
In on drive sleeve (6) inner wall, and respectively close to drive sleeve (6) both ends, multiple L-type cracks are equidistantly provided on the drive sleeve (6),
And inwardly bending forms clip plate (9) to the part outer tube (3) of the corresponding crack location, the transverse crack in the L-type crack and
The angle of Vertical Cracks is acute angle, and transverse crack is arcuate structure, and interior swivel nut (4) is placed in drive sleeve (6), drive ring (2)
It is placed on interior swivel nut (4) one end, and is fitted with the stop collar (8) on drive sleeve (6) inner wall on the lower, the drive ring (2)
Outer diameter is gradually increased from bottom to top, and clip plate (9) bottom is located at the top of drive ring (2), and screw rod (1) runs through housing
It manages (3), and is passed through out of interior swivel nut (4), the screw rod (1) and interior swivel nut (4) bolt, two rubber rings (5) are respectively placed in
Outer tube (3) both ends, and inner wall fits with screw rod (1) outside respectively.
In use, screw rod (1) one end is connected with external motor first, then attachment base (7) is connected with suspension arm, into
When row lifting, external motor drives screw rod (1) rotation, and interior swivel nut (4) and screw rod (1) are spirally connected, and then interior swivel nut (4) is along screw rod
(1) it is moved, interior swivel nut (4) drives drive ring (2) mobile, and drive ring (2) pushes clip plate (9), and then pushes drive sleeve
(6) mobile, drive sleeve (6) drives outer tube (3) mobile along screw rod (1), and then outer tube (3) is driven by attachment base (7)
It suspends arm to carry out, realizes lifting movement；
During lifting, suspension arm applies active force to outer tube (3), since interior swivel nut (4) and outer tube (3) be not straight
Contact, and then interior swivel nut (4) does not stress, interior swivel nut (4) and screw rod (1) keep vertical, guarantee the mobile fluency of suspension arm；
The design of the rubber ring (5), buffers the stress of outer tube (3)；
Reach in machinery production, the purpose of screw propulsion is carried out to suspension arm.
