Concrete, described bearing seat is in the below of described coupler.
Compared with prior art, the beneficial effect of a kind of automatic material gripping mechanism of the utility model is:
1, with rotation-controlled direction and speed and position accurately servomotor instead of original cylinder, improve the motion precision of automatic material gripping mechanism;
2, movable leading screw and portable plate are arranged to ball screw, the circumference convert rotational motion of movable leading screw is become the straight-line motion up and down of portable plate, the noise that automatic material gripping mechanism produces can be reduced on the one hand, improve the service life of automatic material gripping mechanism on the other hand, thus decrease service expenditure, reduce cost.
[accompanying drawing explanation]
Fig. 1 is the structural representation of the utility model automatic material gripping mechanism.
Numeral in figure:
100 automatic material gripping mechanisms; 1 frame, 11 cavitys; 2 servomotors; 3 drivings device, 31 movable leading screws, 311 bearing seats, 32 coupler, 33 portable plates; 4 material catching apparatus, 41 cylinders, 42 material grasping hands.
[detailed description of the invention]
Please refer to Fig. 1, the utility model is a kind of automatic material gripping mechanism 100, it comprises frame 1, be positioned at the actuating device on frame 1 top, driving device 3 and material catching apparatus 4, actuating device is made up of the servomotor 2 that can control torque and rotational speed, is provided with through cavity 11 in frame 1 from top to bottom.
Servomotor 2 refers to the driving engine controlling mechanical element running in Fu, is the indirect transmission system of a kind of subsidy motor.Servomotor 2 can control its rotor speed, and positional precision is very accurate, voltage signal can be converted into torque and rotational speed with drived control object.The utility model servomotor 2 instead of original cylinder, and no matter can operate by held stationary at a high speed or in low cruise, positional precision is higher, improves the motion precision of automatic material gripping mechanism 100; Compared to original cylinder, its operating noise obviously reduces.
Please refer to Fig. 1, driving device 3 comprises and to be contained in cavity 11 and the threaded movable leading screw 31 of appearance tool, one end connect servomotor 2 bottom and the coupler 32 on other end connection activity leading screw 31 top and be connected to the portable plate 33 of movable leading screw 31 bottom.Portable plate 33 has the screw with ball with movable leading screw 31 appearance screw thread fit, movable leading screw 31 stretches out the lower surface of portable plate 33 downwards so that portable plate 33 can carry out rising or declining on movable leading screw 31, and portable plate 33 and movable leading screw 31 constitute ball-screw-transmission.Movable leading screw 31 has for preventing movable leading screw 31 from rocking and being contained in the bearing seat 311 in cavity 11.
Ball-screw-transmission is that gyroscopic movement is converted into straight-line motion, or be the desirable product of gyroscopic movement by transform linear motion, be made up of screw rod, nut and ball, there is stable drive and can larger power be transmitted, can self-locking and there is the advantage of accurate displacement.Ball-screw is commonly called as screw mandrel, and its principle of work is that portable plate 33 just can change into upper and lower straight-line motion with the rotational angle of screw mandrel according to the helical pitch of corresponding specification when the threaded movable screw mandrel 31 of appearance tool is as active body.Bearing is become sliding action from original scroll actions by ball-screw, has less friction drag, not easy to wear, adds the service life of automatic material gripping mechanism 100; Ball-screw-transmission has high-precision guarantee, makes the action precision of automatic material gripping mechanism 100 not only high but also guaranteed.
