Center fixation type quick clamping mechanical hand used for forging robot

Abstract

The invention discloses a center fixation type quick clamping mechanical hand used for a forging robot. The center fixation type quick clamping mechanical hand comprises a clamp base, wherein a heat-resistant air cylinder is longitudinally arranged on the rear part of the clamp base; the rear end of the heat-resistant air cylinder is fixedly equipped with a connecting flange; a central pulling disc is fixedly arranged on a piston rod of the heat-resistant air cylinder through a connecting pin device; the central pulling disc, a left clamping claw fixed base and a right clamping claw fixed baseseparately form a parallel four-bar linkage mechanism; and the purpose of keeping the clamping center of the mechanical hand unchanged by symmetrically controlling synchronous movement of the left clamping claw fixed base and the right clamping claw fixed base in the left-right direction through the central pulling disc and transversely arranging a high-temperature-resistant guide rail; and a left clamping claw and a right clamping claw are separately connected on the left clamping claw fixed base and the right clamping claw fixed base through quick replacing mechanisms. The center fixation type quick clamping mechanical hand disclosed by the invention can be used for quickly producing in case of not switching procedures for workpieces of different specifications, one clamping claw can meet workpiece clamping needs within certain outer diameter range, and replacing times of the clamping claws are reduced.

Description

technical field [0001] The invention relates to a center-fixed fast clamping manipulator used for a forging robot. Background technique [0002] At present, in the production process of forging robots clamping workpieces with manipulators, in order to realize the clamping of shaft disk workpieces with different diameters, a production method of one workpiece corresponding to one gripper and operating program control is usually adopted. In production, because the teaching steps of the robot’s running path for each workpiece are cumbersome, and the workpiece specifications are usually large, the workload of debugging the robot’s running program is increased; Frequent, the process of program switching is prone to errors, which is likely to cause safety accidents; at the same time, it takes a long time to wait for the cooling of the jaws during the replacement process of the manipulator jaws, which cannot improve production efficiency and other issues.
