Abstract

The invention discloses a translation speed variable mechanical paw. The translation speed variable mechanical paw comprises a stepping motor, a coupler, a transmission mechanism, a first clamping piece, a second clamping piece, a first clamping finger, a second clamping finger, a base plate, a front baffle, a back baffle, a sliding block and a sliding linear guideway. The mechanical paw is driven by the stepping motor; the rotation of the motor is transformed into the movement of the transmission sliding block through a screw nut transmission pair; meanwhile, ball bearings on two cylindrical pins of the transmission sliding block slide in a first arc-shaped sliding groove and a second arc-shaped sliding groove correspondingly and drive the first clamping piece and the second clamping piece to conduct opening or closing movement; and speed varying movement of fingertips of the mechanical paw is achieved through changes of curve parameters of the arc-shaped sliding grooves, and that is, closing in deceleration and opening in acceleration. According to the feature of the translation speed variable mechanical paw, the impact when the fingertips touch fragile targeted objects is reduced; the clamping is stable and reliable; and the working efficiency of the mechanical paw is improved.

Description

technical field [0001] The invention relates to the technical field of robots, in particular to a translational speed-changing mechanical claw. Background technique [0002] The robot gripper is the executive part located at the end of the robot arm. The flexibility, accuracy and stability of the gripper when grasping the target is an important indicator to measure the design level of the robot gripper. At present, the grippers of industrial robots can be divided into pneumatic type, hydraulic type, electric type, etc. according to the driving mode; Due to the simple structure and low cost of the pneumatic gripper, it is most commonly used in the field of automation where the requirements are not very high. Compared with the pneumatic gripper, the electric gripper has the following characteristics: the opening and closing of the electric gripper has the function of programmable control, which can realize multi-point positioning; the acceleration and deceleration of the elec...
