An electronic control object bearing platform 2 comprises a main frame 1, an object bearing platform 2, an adjusting device, a three-dimensional force sensor 3, a handle 4 and a controller 5 for controlling the adjusting device to carry out displacement adjustment on the object bearing platform 2 according to a sensing signal of the three-dimensional force sensor 3. Wherein, the adjusting device is connected with the object bearing platform 2 and the main frame 1 for the object bearing platform 2 to carry out displacement adjustment; the handle 4 is fixedly connected with the sensing end of the three-dimensional force sensor 3; the output end of the three-dimensional force sensor 3 is electrically connected with the controller 5.
In the present embodiment, the adjusting device includes a first transmission mechanism 6, a second transmission mechanism 7, and a third transmission mechanism 8.
The first transmission mechanism 6 comprises a first motor 61 and a first output shaft 62, and the first output shaft 62 is fixed with the object bearing table 2;
the second transmission mechanism 7 includes a second motor 71 and a second output shaft 72, and the second output shaft 72 is used for mounting and fixing the first motor 61. The first output shaft 62 is vertically disposed and the second output shaft 72 is horizontally disposed.
The third transmission mechanism 8 is a vertical transmission mechanism, and a displacement part of the third transmission mechanism is used for installing and fixing the second motor 71. In this embodiment, the vertical transmission mechanism includes a screw 81, a sliding table 82, and a third motor 83 for driving the screw 81 to rotate, and two ends of the screw 81 are connected through a bearing and fixedly disposed on the main frame 1. The sliding table 82 is vertically connected with the main frame 1 in a sliding manner and is in threaded connection with the screw rod 81; the second motor 71 is fixed to the slide table 82.
In this embodiment, the first transmission mechanism 6, the second transmission mechanism 7, and the third transmission mechanism 8 are mutually connected in a transmission manner, wherein the first transmission mechanism 6 realizes the rotation of the object bearing table 2 in the Y-axis direction, the second transmission mechanism 7 realizes the rotation of the object bearing table 2 in the X-axis direction, and the third transmission mechanism 8 realizes the movement of the object bearing table 2 in the Z-axis direction.
The controlled ends of the first motor 61, the second motor 71 and the third motor 83 are electrically connected to the control end of the controller 5.
In the present embodiment, the three-dimensional force sensor 3 is fixed to the platform 2.
Illustratively, the force acting on the handle 4 is captured by the three-dimensional force sensor 3 and is decomposed into three directions of x, y and z, and then the three-dimensional force sensor 3 converts the three directions of force into three paths of electric signals of x, y and z, and transmits the three paths of electric signals to the controller 5, and the controller 5 determines the three directions of force by detecting the magnitudes of the three paths of electric signals of x, y and z, so as to control the moving directions and speeds of the first motor 61, the second motor 71 and the third motor 83. Correspondingly, the force in the x direction controls the first motor 61 to drive the object bearing table 2 to rotate left and right; the force in the y direction is applied to the second motor 71 to rotate, so as to drive the first transmission mechanism 6 to rotate back and forth; the force in the z direction controls the third motor 83 to rotate, and the upper body is driven to ascend and descend by the sliding table 82 of the screw rod 81.
Thus, the first motor 61, the second motor 71 and the third motor 83 can be controlled by the control of the key or the force on the handle 4. When the electric control is needed, the posture of the object bearing table 2 can be adjusted only by controlling the first motor 61, the second motor 71 and the third motor 83 through keys; when manual adjustment is needed, the posture of the object bearing table 2 can be adjusted only by slightly pulling the handle 4, the larger the force is, the faster the object bearing table 2 moves, and the motors can move simultaneously, so that the movement flexibility is improved, the convenience is brought to one-time positioning, and repeated adjustment is not needed. In addition, no matter the manual adjustment or the key adjustment is carried out, the motor movement is finally controlled by the controller 5, so that the weight of the load basically does not influence the manual control.
Through the arrangement, the problems of excessive dead plate adjustment and poor flexibility in the prior art are perfectly solved, the mode of the three-dimensional force sensor 3 is adopted, when manual adjustment is needed, force acts on the handle 4 instead of directly acting on the joint position to be rotated, therefore, the force on the handle 4 is transmitted to the three-dimensional force sensor 3, the three-dimensional force sensor 3 converts the force into an analog electric signal and transmits the analog electric signal to the controller 5, and then the controller 5 controls the motor on the object bearing table 2 to move according to the acquired signal so as to adjust the pose of the object bearing table 2. In addition, the controller 5 can also adjust the rotating speed and the direction of the motor according to the force, and the first motor 61, the second motor 71 and the third motor 83 can be linked simultaneously, so that the adjustment is more flexible and convenient.
The foregoing is a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the principle of the present invention, and these improvements and decorations are also considered as the protection scope of the present invention.
