Tool replacing manipulator of numerically-controlled machining center

Abstract

The invention discloses a tool replacing manipulator of a numerically-controlled machining center in the technical field of machine tool tool replacing equipment. The tool replacing manipulator of thenumerically-controlled machining center comprises a connecting part, tool claws, a mechanical arm body and self-locking mechanisms; the connecting part is connected with a machining center body; thetool claws are located at the two ends of the mechanical arm body; the upper surface of the mechanical arm body is provided with countersunk grooves, and the two ends of the mechanical arm body are each provided with a through hole used for containing a tool jacking rod; and each self-locking mechanism comprises the corresponding tool jacking rod used for fixing a tool, a sliding block arranged inthe corresponding countersunk groove and a locking pin matched with the sliding block. According to the tool replacing manipulator of the numerically-controlled machining center, through the interaction force of the locking pins and the sliding blocks in the self-locking mechanisms, the sliding blocks slide in the countersunk grooves and drive the tool jacking rods to move, automatic tool replacing of the numerically-controlled machining center tool is completed, the process is simple, and operation of workers is convenient; and the tool jacking rods are pushed to make contact with the tool through first springs and second springs of the self-locking mechanisms when the tool is replaced, tool falling is prevented, and safe and continuous tool replacing work is guaranteed.

Description

technical field [0001] The invention relates to the technical field of tool changing equipment for machine tools, in particular to a tool changing manipulator of a numerically controlled machining center. Background technique [0002] At present, my country's machine tool industry has entered the stage of replacing ordinary machine tools with CNC machine tools, and the demand for machining centers is clearly on the rise. This is mainly due to the fact that the cost of adding automatic tool changers is not much, but the effective utilization of machine tools is rapidly increasing. The labor intensity is reduced, and the processing cost is reduced. Therefore, the automatic tool changer is very important to improve the processing efficiency of the machine tool, reduce the labor intensity and processing cost of workers, and the automatic tool changer is the most critical part of the automatic tool changer. [0003] The tool changing manipulator on the existing automatic tool cha...
