Description
Technical field
The utility model belongs to hitching machinery technical field, in particular to a kind of magnet hitching machinery arm.
Background technique
A kind of widely used traction mechanism of mechanical arm body, existing mechanical arm body generally use screw rod or belt
As driving member, no matter that kind of drive requires driving member to be fixed on sliding block or has connect by driving member with sliding block
Come, it is therefore necessary to the drive mechanism inside mechanical arm body be exposed to the external environment, when the external world is corrosive environment
It waits, mechanical structure, especially metal structure are easily corroded or got rusty, and it is short to will cause device longevity, or need frequently more
The problem of changing transmission parts, for example, by using the mode that screw rod plus nut are driven, screw rod and nut can all be corroded.
In view of this, the present inventor improves traction mechanism, especial manufacture goes out a kind of magnetic for avoiding corrosion driving member
Thus railway traction mechanical arm, this case generate.
Utility model content
The purpose of this utility model is to provide a kind of magnet hitching machinery arms, in such a way that magnet is drawn and is sealed
It avoids driving member from being corroded, improves driving member service life, reduce maintenance cost.
To achieve the goals above, the technical solution of the utility model is as follows:
A kind of magnet hitching machinery arm, including mechanical arm body, sealing cover, motor, shaft coupling, screw rod, nut, sliding block,
Upper magnetic box and lower magnetic box；Motor is set to mechanical arm body one end, and sealing cover lid closes at the top of mechanical arm body, makes sealing cover and machine
Seal chamber is formed between tool arm body, screw rod is rotatably arranged in seal chamber, and screw rod one end passes through shaft coupling and motor
Output shaft be connected, the screw rod other end is arranged a bearing；The nut is mounted on screw rod, and lower magnetic box is fixed on nut top
Portion, the sliding block are set on sealing cover, and upper magnetic box corresponds to lower magnetic box and is mounted on slider bottom.
Further, the upper magnetic box bottom surface and lower magnetic box top surface are affixed on sealing cover upper and lower surfaces respectively.
Further, the upper magnetic box and lower magnetic box are made of magnetic box and the magnet being arranged in magnetic box, and on
Magnetic holder and lower magnetic box all have the two groups of magnet in left and right, and the magnet modes of emplacement of two groups of upper magnetic box and lower magnetic box or so is opposite.
After adopting the above scheme, when utility model works, motor drives screw rod to rotate by shaft coupling, the spiral shell on screw rod
It is female to the left/move right, the upper magnetic box band movable slider of the lower magnetic box cooperation slider bottom on nut is run with nut.
The utility model has the following beneficial effects: sharp magnet realizes the linkage between driving member and sliding block and will by sealing cover
Driving member (i.e. screw rod and nut) is fully sealed, its connecing with external environment is effectively completely cut off under the premise of guaranteeing transmission stability
Touching, it is ensured that driving member will not be corroded, and extend the service life of drive mechanism.
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Detailed description of the invention
Fig. 1 is the sectional view of the utility model.
Label declaration
Mechanical arm body 1, seal chamber 1a, sealing cover 2, motor 3, shaft coupling 4, screw rod 5, nut 6, sliding block 7, upper magnetic box 8,
Lower magnetic box 9, bearing 10, magnetic box 11, magnet 12.
Specific embodiment
As shown in Figure 1, a kind of magnet hitching machinery arm that the utility model embodiment one discloses, including mechanical arm body 1,
Sealing cover 2, motor 3, shaft coupling 4, screw rod 5, nut 6, sliding block 7, upper magnetic box 8 and lower magnetic box 9；Motor 3 is set to mechanical arm body 1
One end, the lid of sealing cover 2 close at 1 top of mechanical arm body, make to form seal chamber 1a, screw rod between sealing cover 2 and mechanical arm body 1
5 are rotatably arranged in seal chamber 1a, and 5 one end of screw rod is connected by shaft coupling 4 and the output shaft 3a of motor 3, silk
5 other end of bar is arranged a bearing 10；Nut 6 is mounted on screw rod 5, and lower magnetic box 9 is fixed on 6 top of nut, and sliding block 7 is set to sealing
On lid 2, upper magnetic box 8 corresponds to lower magnetic box 9 and is mounted on 7 bottom of sliding block.
When the magnet traction mechanism work of the present embodiment, motor 3 drives screw rod 5 to rotate by shaft coupling 4, on screw rod 5
Nut 6 to the left/move right, lower magnetic box 9 on nut 6 cooperates the upper magnetic box 8 of 7 bottom of sliding block to transport with movable slider 7 with nut 6
Row.
Further, 8 bottom surface of upper magnetic box Yu 9 top surface of lower magnetic box of the present embodiment are affixed on 2 upper surface of sealing cover and following table respectively
Face.So that upper magnetic box 8 and lower magnetic box 9, apart from closest, the two gravitation is maximum, guarantees that sliding block is stablized with nut and moves.
Further, the upper magnetic box 8 of the present embodiment and lower magnetic box 9 are by magnetic box 11 and the magnet being arranged in magnetic box
12 compositions, and upper magnetic box 8 and lower magnetic box 9 all have the two groups of magnet 12 in left and right, and the magnetic of two groups of the left and right of upper magnetic box 8 and lower magnetic box
12 modes of emplacement of iron is contrary.For example, the left side modes of emplacement of upper magnetic box 8 is S under upper N, the right is placed as N under S, lower magnetic box
9 left side modes of emplacement is N under upper S, and the right is placed as S under N, and the above sealing structure is in mechanical arm body and sealing cover
Portion.When the operation of screw rod 5 is misplaced by resistance with nut 6, two groups of left and right magnet and the lower magnetic box 9 of upper magnetic box 8 misplace,
I.e. the 8 one group of magnet 12 in right side of upper magnetic box is displaced to the 8 one group of magnet in left side of 9 one group of left side magnet of lower magnetic box, 12 top or upper magnetic box
12 are displaced to one group of the right side of lower magnetic box 9 magnet, 12 top, will lead to magnet 12 see it is mutually exclusive so that two groups of magnet 12 can be with
Quick-return does not easily cause dislocation or disengaging to original corresponding position.
The above are only specific embodiments of the present invention, not to the restriction of the protection scope of the utility model.
The equivalent variations that all mentalities of designing according to this case are done, each falls within the protection scope of this case.
