Specific embodiment
To be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, below
In conjunction with specific embodiment, the utility model is further described.
As shown in Figure 1-3, a kind of stacking machine rotational structure, including stacking base 5, it is fixedly installed inside stacking base 5
Four elevating screws 12 are provided with the first electric up-down seat 13 and the second electric up-down seat 15, the first electricity between elevating screw 12
Dynamic 13 upper end of lifting seat rotation is provided with second connecting rod 11, the rotation of 15 upper end of the second electric up-down seat be provided with first connecting rod 4 with
Second connecting rod 11, large arm 3 before 5 upper end of stacking base is provided with by shaft rotation, and run through and be movably set with rear large arm 2, after
2 lower end of large arm is provided through connection shaft 16, and the first electric up-down seat 13 is connected by second connecting rod 11 with shaft 16 is connect,
Second electric up-down seat 15 is connected by third connecting rod 14 with shaft 16 is connect, and the second electric up-down seat 15 passes through first connecting rod
4 be rotatablely connected in the middle part of rear large arm 2, rear 2 upper end of large arm is rotatably connected to forearm 7, and preceding 3 upper end of large arm and forearm 7 are rotatablely connected,
Forearm 7 is fixedly installed electric cylinder 6 by fixed block 1 by one end of nearby large arm 3, and the rotation of 7 other end of forearm is provided with work
It starts wrist 9, electric cylinder 6 is connect by drive lead screw 8 with activity wrist 9, and 9 lower end of activity wrist is provided with clamping jaw 10;
Large arm 2, preceding large arm 3 and forearm 7 are the hollow double-deck component afterwards;Electric cylinder 6 is internally provided with to be engaged with drive lead screw 8
Servo motor;First electric up-down seat 13 is internally provided with the lifting engaged with elevating screw 12 with the second electric up-down seat 15
Motor;Clamping jaw 10 is electronic screw rod clamping jaw, and is detachably connected with activity wrist 9;First connecting rod 4, third connecting rod 14 and rear big
The composition of arm 2 can not relatively movable triangular structure.
It should be noted that the utility model is a kind of stacking machine rotational structure, in use, clamping jaw 10 is mounted on activity
The lower end of wrist 9 clamps object using clamping jaw 10, and when adjusting object angle, electric cylinder 6 is operated, and drives drive lead screw 8 flexible,
The rotation of 8 drive activity wrist 9 of drive lead screw is lived so as to adjust 10 angle of clamping jaw relative to traditional tripod and screw rod driving
Starting, the mode that wrist 9 rotates is more succinct, and occupied space is smaller and rotational efficienty is higher, when adjusting object front-rear position, first
Electric up-down seat 13 remains stationary, the lifting of the second electric up-down seat 15, so that first connecting rod 4 and third connecting rod 14 is driven to go up and down,
Because first connecting rod 4, third connecting rod 14 and rear large arm 2 composition can not relatively movable triangle, first connecting rod 4 and thirds
Large arm 2 rotates after connecting rod 14 drives, and forearm 7 is rotatablely connected by preceding large arm 3 and stacking base 5, large arm 2 later rotation band
