Specific embodiment
The utility model is illustrated with reference to the accompanying drawing
As depicted in figs. 1 and 2, a kind of mechanical self balancing device, including holding rod 1, change bar 2, compact heap 3,4 and of balance weight
Drawstring 5,2 end of bar that becomes are mounted on holding rod 1 by what shaft 6 was freely rotated, are set on the change bar 2 of 1 side of holding rod
There is the limited post 13 of a stretching, the compact heap 3 is cylindrical part, and (the present embodiment is sleeve knot to compact heap 3 by sliding pair
Structure has specially opened the slide opening of a transverse direction on holding rod 1,3 back side of compact heap is equipped with a slide bar being mounted in slide opening, sliding
The axis in hole is vertical with holding rod side) it is vertical be mounted on holding rod 1, between compact heap 3 and holding rod 1 be equipped with so that pressure
The tight outwardly directed reset spring 7 of block 3 is equipped with the slide opening 8 vertical with its axis direction, compact heap about 3 two on the outside of compact heap 3
Fabric wheel 10 is equipped on the holding rod 1 of side, the balance weight 4 is mounted on compact heap by what revolute pair (bearing) was freely rotated
On 3, balance weight, compact heap and shaft are all coaxial arrangements in the present embodiment, and balance weight 4 includes the counterweight 12 and position positioned at bottom
In its top two sides gag lever post 11, when balance weight 4 in a free state, the gag lever post 11 of two sides is in horizontal
State, is equipped with angle pulley 9 at the top of the holding rod 1, and 5 one end of drawstring, which is fixed on, becomes on bar 2 that (the present embodiment is fixed on limited post 13
On), the other end bypasses after angle pulley 9 successively from the fabric wheel of the lower section of fabric wheel 10, slide opening 8 and lower section on compact heap 3
10 lower sections naturally droop or are fixed on 1 lower end of holding rod after passing through, and when pulling 5 lower end of drawstring, drawstring 5 passes through upper and lower crimping
Wheel 10 and slide opening 8 effect so that compact heap 3 close to holding rod 1 move so that balance weight 4 close to holding rod 1 and the two it
Between generate the rubbing surface for keeping relative position fixed, when further pulling on drawstring 5, become bar 2 and raise up until limited post 13 encounters limit
Position bar 11 stops, and when unclamping drawstring 5, compact heap 3 and balance weight 4 separate holding rod 1, balance weight 4 under the effect of reset spring 7 are extensive
Multiple free movement, because balance weight 4 is in a free state, the gag lever post 11 of two sides is constantly in horizontality, therefore elected
After the posture (mainly angle) for determining holding rod 1, no matter holding rod 1 is in any posture, and the gag lever post 11 of balancing pole is all place
In horizontality, when pulling drawstring 5, since drawstring 5 oppresses compact heap 3, compact heap 3 overcomes the elastic force of reset spring 7 to hand
It holds bar 1 to draw close, until balance weight 4 is contacted with holding rod 1 generates frictional force, balance weight 4 and 1 relative position of holding rod are kept at this time
It is fixed, and the gag lever post 11 of balancing pole two sides is in horizontality (holding rod posture is constant at this time), further pulls on drawstring 5
When, become bar 2 in addition to drawstring 5 will pull and raise up outer, raises up angle increase with bar 2 is become, power needed for drawstring 5 also becomes larger, draws simultaneously
The pressing force of 5 pairs of compact heaps 3 of restricting also becomes larger namely normal pressure that balance weight 4 is contacted with holding rod 1 becomes larger, and frictional force becomes larger, because
This structure has self-locking, when so that drawstring 5 pulling, has stable relative position between balance weight 4 and holding rod 1,
After the limited post 13 for becoming bar 2 touches gag lever post 11, become bar 2 and reach maximum and raise up angle, therefore can be set by selection
To set change bar 2, with respect to the horizontal plane maximum raises up the length or the distance between limited post 13 and shaft 6 of fixing limit bar 11
Angle, when due to original state, no matter what posture holding rod 1 is in, the gag lever post 11 of balance weight 4 be all it is horizontal, therefore
Become the with respect to the horizontal plane maximum angle that raises up of bar 2 be it is constant, not when original state the posture of holding rod 1 due to change.
It should be pointed out that the reset spring 7 could alternatively be other elastomeric elements, about 3 two sides of compact heap
Fabric wheel 10 could alternatively be slide opening, drawstring 5 is from passing through the effect played as fabric wheel 10 in slide opening.
As a kind of more excellent embodiment, the compact heap 3 is hollowed tubular member, and hollow tube and shaft 6 are coaxially disposed, institute
Hollow tube is stated to be mounted on holding rod 1 by linear bearing, the drawstring 5 is wirerope or nylon rope, the shaft 6 with become bar
It is installed between 2 or holding rod 1 using bearing.
The machinery self balancing device is for that can be any angle feelings in holding rod 1 in the mechanical arm of fruit picking equipment
Under condition, change bar 2 is kept to raise up to a fixed angle, while any need can also be applied to and quickly select the constant angle that raises up
Mechanical arm occasion.Contact surface between the balance weight and holding rod is the coarse rubbing surface equipped with anti-skid chequer, Ke Yizeng
Frictional force when big balance weight and holding rod contact helps to provide stability of the balance weight when compressing with holding rod.
It should also be noted that the structure of similar hoist engine can be arranged in 1 lower end of holding rod, pulled by hoist engine
Drawstring 5 is pulled without manpower, can be by the utility model application extension to bigger mechanical arm different areas of activity.
