Arm unfolding gripper mechanism of industrial robot

Abstract

The invention provides an arm unfolding gripper mechanism of an industrial robot. The arm unfolding gripper mechanism comprises a gripper frame, a driving device, a pushing fixing piece, a movable rotating arm, a fixed rotating arm, a fixed shaft and push rods on the two sides of the gripper driving device, wherein the push rods drive the pushing fixing piece to horizontally move towards the two sides, the pushing fixing piece pushes the movable rotating arm and the fixed rotating arm to move, so that the movable rotating arm and the fixed rotating arm do composite motion; the inclination angle of the fixed rotating arm is changed while the fixed rotating arm moves outwards, the fixed rotating arm is gradually inclined from the vertical direction to the outside, and the fixed rotating armdrives a gripper to move, so that the gripper is opened towards the two sides; and when the driving device tightens the pushing fixing piece, the angle of the fixed rotating arm is gradually changed to the vertical direction, the fixed rotating arm drives the gripper to move, so that the gripper is tightened towards the inner side. According to the arm unfolding gripper mechanism, large-stroke movement of the gripper is realized through a small-stroke movement mechanism, and the capacity of the gripper is improved. The arm unfolding gripper mechanism is ingenious in structure, elegant in appearance, capable of rapidly and effectively driving the gripper to move, capable of guaranteeing that automatic feeding and discharging equipment is smooth and stable during working, high in applicability and beneficial to assembly, disassembly and maintenance.

Description

technical field [0001] The invention relates to the technical field of industrial robots, in particular to an arm gripper mechanism of an industrial robot. Background technique [0002] In the field of mechanical processing, robot technology has been widely used due to its high precision and high efficiency. On the existing automatic loading and unloading equipment in the mechanical industry automation industry, the position of the workpiece is adjusted when the gripper mechanism of the industrial robot grabs the workpiece. It is difficult to control, the gripper mechanism has the phenomenon of not grasping the workpiece tightly or grasping the workpiece, and the structure is also too thin, there are defects such as deformation, poor precision and low life. In some special industries, the added parts The shape is complex, and the industrial robot gripper of general automatic loading and unloading equipment cannot grasp, grasp or grasp the workpiece accurately, which leads to...

[0002] In the field of mechanical processing, robot technology has been widely used due to its high precision and high efficiency. On the existing automatic loading and unloading equipment in the mechanical industry automation industry, the position of the workpiece is adjusted when the gripper mechanism of the industrial robot grabs the workpiece. It is difficult to control, the gripper mechanism has the phenomenon of not grasping the workpiece tightly or grasping the workpiece, and the structure is also too thin, there are defects such as deformation, poor precision and low life. In some special industries, the added parts The shape is complex, and the industrial robot gripper of general automatic loading and unloading equipment cannot grasp, grasp or grasp the workpiece accurately, which leads to the unrealization or low efficiency of the automatic production line of the product, and the high maintenance cost, which restricts the production capacity of the enterprise's automatic production line caused certain economic losses and low cost performance
