Description

Technical Field

[0001] The utility model relates to the technical field of numerical control machine tools, in particular to a machining tool for a machining table of a numerical control machine tool. Background Art

[0002] A CNC machine tool is an automated machine tool equipped with a program control system. It controls the movement of the machine tool by setting control codes or other symbolic instructions, decoding them, and then issuing instructions after calculation processing. It treats the workpieces and processes them in accordance with the shapes and sizes required by the drawings. During the processing, the mold base needs to be placed on a fixture for fixation. The common fixture is a screw structure, which drives the two clamps to move relative to each other and fix the mold base.

[0003] According to the "A CNC machine tool processing table processing tooling" with Chinese patent publication number CN219336975U, it mainly describes that the two ends of the workpiece can be clamped by setting a U-shaped frame and a screw rod, which is convenient for CNC processing. At the same time, the driving component and the threaded component are set so that the threaded block can drive the entire clamping component to move vertically, and under the action of the cylinder, it can also drive the clamping component to move horizontally, so as to cooperate with each other to process different positions of the workpiece. By setting a mounting frame, it can be fixedly installed with the processing equipment, and at the same time, the height of the processing equipment can be adjusted under the action of the hydraulic cylinder. The processing angle can be adjusted under the action of the first driving motor at the bottom, which is convenient for the whole processing equipment to process without dead angles and increase the overall processing efficiency. When the mold base is clamped by the splint, the side area clamped by the clamp is large, which affects the processing requirements of part of the mold base, resulting in the inability to process the side and reducing the processing effect.

[0004] Therefore, a CNC machine table processing tool is proposed to solve the problem that when the mold base is clamped by a splint, the side area clamped by the clamp is large, which affects the processing requirements of part of the mold base, resulting in the side being unable to be processed and the processing effect being reduced.
