Embodiment 1

[0018] like figure 1 As shown, an electric manipulator internal grasping device based on a rack and pinion and a crank connecting rod includes a screw 1, on which a nut 2 cooperating with it is installed, and the nut 2 is arranged at equal intervals along its outer peripheral surface There are two racks 3 parallel to the screw rod 1, which are symmetrically arranged on both sides of the nut 2, each rack 3 is provided with a gear 4 meshed with it, and each gear 4 is hinged with Crank connecting rod 5, the end of described crank connecting rod 5 is connected with grasping pressure head 6, and described screw rod 2 is driven by reduction motor 8.

[0019] The electric energy drives the reduction motor 8 to rotate in the forward direction, and the rotating reduction motor 8 drives the screw rod 1 connected to it to rotate in the forward direction, and the screw rod 1 drives the nut 2 and the left and right racks 3 connected to the nut 2 to move upward. The left and right gears 4 ...

Embodiment 2

[0023] An electric manipulator internal grasping device based on a rack and pinion and a crank connecting rod, comprising a screw 1, on which a nut 2 cooperating with the screw 1 is installed; The racks 3 parallel to the screw rod 1, the three racks 3 are arranged on the outer peripheral surface of the nut 2 at intervals of 120°, and each rack 3 is provided with a gear 4 meshing with it, so Each gear 4 is hinged with a crank connecting rod 5 , and the end of the crank connecting rod 5 is connected with a grasping pressure head 6 , and the screw rod 2 is driven by a reduction motor 8 .

[0024] The only difference between this embodiment 2 (not shown) and embodiment 1 is that there are three racks 3 arranged along the outer peripheral surface of the nut 2 at an angle of 120° to each other, so as to facilitate the three-point support for the cylindrical workpiece , to achieve fixation, thereby expanding the range of use of the internal grabbing device, the principle is the same ...

Embodiment 3

[0026] An electric manipulator internal grasping device based on a rack and pinion and a crank connecting rod, comprising a screw 1, on which a nut 2 cooperating with the screw 1 is mounted, and on the nut 2 there are four and The racks 3 parallel to the screw 1, the four racks 3 are arranged on the outer peripheral surface of the nut 2 at intervals of 90°, and each rack 3 is provided with a gear 4 meshing with it, so Each gear 4 is hinged with a crank connecting rod 5 , and the end of the crank connecting rod 5 is connected with a grasping pressure head 6 , and the screw rod 2 is driven by a reduction motor 8 .

[0027] The only difference between this embodiment 3 (not shown) and embodiment 1 is that there are four racks 3 arranged along the outer peripheral surface of the nut 2 at an angle of 90° to each other, which is convenient for realizing four racks for larger square workpieces. The points are symmetrically supported to achieve fixation, thereby expanding the scope of...

Abstract

An electrical manipulator internal gripping device based on gears, racks and crank connection rods comprises a screw, wherein a nut matched with the screw is installed on the screw, at least two racks parallel to the screw are arranged on the outer peripheral face of the upper edge of the nut at intervals, a gear meshed with the corresponding rack is arranged on each rack, the crank connection rods are hinged to the gears, and the tail ends of the crank connection rods are connected with gripping press heads. The internal gripping device can be installed on a crane, a production machine and other manipulators to replace dull, repeated or burdensome manual labor and can replace manual operation in hazardous environment, accordingly mechanical and automatic production is achieved, working efficiency is improved, labor conditions are improved, and the personal safety problems caused by fatigue and the like of workers are deceased.

Description

technical field [0001] The invention relates to an electric manipulator internal grasping device based on a rack and pinion and a crank connecting rod, which belongs to the field of mechanical technology. Background technique [0002] Fields such as logistics, production lines and dangerous goods handling need to grab, carry and place articles or workpieces. Due to the complexity of these tasks and the diversification of workplaces, the grabbing, handling and placement of some articles or workpieces in this field still rely on Manually, this does not improve production or work efficiency, and with the shortage of labor, the proportion of material handling and handling costs in the production process gradually increases. In order to realize automation in the fields of logistics, production lines and dangerous goods handling, improve work efficiency, reduce operating costs, and reduce dangerous accidents caused by manual fatigue, etc., the innovative electric manipulator based...
