Embodiment Construction

[0014] Embodiments of the invention will be further described below in conjunction with the accompanying drawings.

[0015] An embodiment of a flexible grasping device of the present invention, such as figure 1 and figure 2 As shown, it includes a frame 1 and a cylinder 2. The base of the cylinder 2 is connected to the upper end of the frame 1. The extension rod of the cylinder 2 protrudes downward and is provided with a rack 3 on the left and right sides at the end. The left and right sides of the rack 3 are Gears 4 are respectively meshed at the two ends, and the gears 4 are connected to the frame 1 through the rotating shaft 5. The gears 4 protrude from the connecting rod 6 in the radial direction, and the outer end of the connecting rod 6 is provided with a flexible grab head 7; the grab head 7 is hinged to the connecting rod 6 , a torsion spring 8 is provided at the hinge to make the flexible grab head 7 press inward, and a limit block is also set at the hinge of the fl...

Abstract

The invention relates to the technical field of mechanical equipment, in particular to a flexible gripping device. The flexible gripping device comprises a frame and an air cylinder; a bottom seat ofthe air cylinder is connected with the upper end of the frame; a rack with left and right sides is arranged at the downward-extended end of an extension bar of the air cylinder; both ends of the rackare separately engaged with gears; the gears are connected with the frame by rotating shafts; connecting rods extend out of the gears in the radial direction; and two flexible gripping fixtures are arranged on the outer end of the connecting rods. According to the flexible gripping device, the gripping is fast and the efficiency is high by adopting the air cylinder to drive the two flexible gripping fixtures to grip bowls, cups and other fragile and irregular items; and through the arrangement of torsional springs on rotating shafts of the two flexible gripping fixtures, part of the gripping fixtures can be deformed outwards, thus stress in gripping is greatly reduced and the chance of broken items is reduced.

Description

technical field [0001] The invention belongs to the technical field of mechanical equipment, and in particular relates to a flexible grabbing device. Background technique [0002] With the continuous development of robot technology, more and more manipulators are used in industrial automation production. Traditional industrial manipulators are generally rigid manipulators, which have good control accuracy and operability, but they are generally large in size, require a large work space, and are not easy to grab some relatively small objects. It is not suitable to grab and carry irregularly shaped, fragile and vulnerable objects. However, in industrial automation production such as the food industry and packaging industry, it is often necessary to grasp and carry such objects. Rigid manipulators cannot complete these tasks, and manual completion of this work is inefficient and has low precision and large errors. Especially on automatic dishwashing and sorting equipment, aft...
