Shock absorption type robot gripper device with self-adjustment function

Abstract

The invention discloses a shock absorption type robot gripper device with a self-adjusting function. The shock absorption type robot gripper device comprises a top connecting device module, a case module, an operation device module and a gripping device module. The device specifically comprises a top hanger rail connecting ring, a side rail connecting buckle, a lifting guide rail, a case framework, a lifting mechanism, a motor, an electric push rod, a case chassis, a grasping forceps packaging upper connecting block, a first-stage spring, a connecting telescopic rod, a push rod bottom end connecting block, a second-stage spring, a grasping forceps packaging lower connecting block and grasping forceps. The motor drives the electric push rod to extend or retract, so that the gripping tongs of the robot gripper are opened or closed; when the opening angle of the grasping forceps is in a maximum state, the first-stage spring and the second-stage spring are in a free telescopic state; when the robot gripper contracts from the maximum state, the first-stage spring and the second-stage spring are always in the stretching state, the clamping resultant force of the gripping tongs is automatically adjusted through the contraction elastic force, and vibration generated in the grabbing and moving process of the robot gripper is absorbed. The device is simple in structure and convenient to operate, and the application range of the device is widened.

Description

technical field [0001] The invention relates to the technical field of a robot gripper, in particular to a self-adjusting shock-absorbing robot gripper device. Background technique [0002] A robot is a high-tech automated production equipment. The robot gripper device is an important part of industrial robots. In the process of industrial robot operation, the robot gripper is required to be accurately positioned, reliable in clamping, and stable in the moving process. In the positioning, clamping and moving of objects by the robot gripper device, due to the influence of factors such as processing errors and unstable working environment on the operated objects, the clamping is unreliable and the objects slip or even fall during the moving process. Falling, to a certain extent, affects the normal operation of the production line of such operations. The patents "a double-clamping mechanical gripper device (201510574545.8)" and "an inclined continuous self-adjusting mechanic...

AI Technical Summary

Problems solved by technology

[0003] In order to overcome the existing robot gripper device in the positioning, clamping and moving of objects, due to the influence of factors such as processing errors and unstable working environment on the operated objects, the clamping is unreliable and the object appears during the moving process. Sliding, even falling, affects the normal operation of this type of operation production line to a certain extent, and the existing patented self-adjustment has low reliability, does not absorb the vibration of the grasping movement process and cannot completely solve the above-mentioned problems. The invention provides a self-adjusting shock-absorbing robot gripper device by using the contraction force of the two-stage tension spring and the shock-absorbing characteristics of the spring
