Abstract

The invention discloses a mechanical arm for a numerical control machine tool and belongs to the field of numerical control machine tools. A mechanical arm for a numerical control machine tool comprises a Y-axis sliding rail provided with a sliding groove and a lead screw, and further comprises a sliding seat in threaded connection with the lead screw and in sliding connection with the interior of the sliding groove, and a Z-axis swing arm with a gripper at the lower end is in sliding connection with the sliding seat; the clamping pieces are arranged on the left inner wall and the right inner wall of the sliding groove and located in the middle of the Y-axis sliding rail, each clamping piece comprises sliding holes formed in the left inner wall and the right inner wall of the sliding groove, sliding blocks are connected into the two sliding holes in a sliding mode, and cambered surface grooves abutting against the outer wall of the lead screw are formed in the opposite side walls of the two sliding blocks. An opening and closing mechanism connected with the two sliding blocks is arranged at the lower end of the Y-axis sliding rail. The oil storage tank is fixedly mounted at the lower end of the Y-axis sliding rail; torsional force and shear force borne by the lead screw during rotation can be effectively shared through the two sliding blocks, and therefore the service life of the lead screw is prolonged.

Description

technical field [0001] The invention relates to the technical field of numerical control machine tools, in particular to a mechanical arm for numerical control machine tools. Background technique [0002] CNC machine tool is the abbreviation of numerical control machine tool, which is an automatic machine tool equipped with a program control system. The control system can logically process programs with control codes or other symbolic instructions, decode them, express them in coded numbers, and input them into the numerical control device through the information carrier. After calculation and processing, various control signals are sent by the numerical control device to control the movement of the machine tool, and the parts are automatically processed according to the shape and size required by the drawing. [0003] Existing CNC machine tools can automatically pick up blanks and place processed parts through the mechanical arm when processing parts. When using a mechanic...
