Claims

[Claims for Utility Model Registration] 1. An arm body; a fixed gripper fixed to the tip of the arm body and forming an arcuate tool grip; and a fixed gripper located opposite to the fixed gripper; a swinging gripper that is swingably supported to open and close and forms an arcuate tool grip; a spring mechanism that biases the rear end of the swinging gripper in a direction in which the gripper closes; the spring mechanism an automatic tool changer comprising: a hydraulic device that supplies pressure oil to maintain the spring biased state; and a swing gripper locking mechanism that presses and fixes the swing gripper in a direction perpendicular to its swing surface. Equipment tool changing arm. 2. The spring mechanism includes a first piston rod that is slidably disposed in a cylinder portion formed in the arm body and has a notch into which the rear end of the swing gripper is inserted and engaged; a spring that contacts and urges the piston rod in a direction in which the swing gripper closes; The tool changing arm according to claim 1, which is a registered utility model, and further comprises: a second piston rod that abuts on the opposite side of the first piston rod; 3. The tool according to claim 2, wherein the hydraulic device has a hydraulic circuit that supplies pressure oil to a side of the second piston rod opposite to the side that is in contact with the spring. Replacement arm. 4. The locking mechanism is characterized in that it includes a pressing member that contacts the swinging gripper from a direction perpendicular to the swinging surface thereof; and a spring that biases the pressing member toward the swinging gripper. A tool changing arm according to claim 1 of the utility model registration claim. 5. The tool changing arm according to claim 4, wherein a tapered surface is formed at the contact portion of the pressing member and the swinging gripper with which the pressing member comes into contact. 6. The tool changing arm according to claim 4, wherein the pressing member is connected to a rod that projects from the arm body in the pressing direction when pressed.
