The invention discloses a processing clamp for a numerically-controlled machine tool, and relates to the field of numerically-controlled equipment. The processing clamp comprises a cylinder, a slidingcolumn, a pressing block, a spring, a secondary block and a fastening bolt. The processing clamp is characterized in that the upper end of the cylinder is connected to the pressing block which is connected to the sliding column; the secondary block is arranged at one side of the sliding column; the spring is arranged between the secondary block and the pressing block and is positioned on the sliding column; and the fastening bolt is arranged on the pressing block. According to the processing clamp for the numerically-controlled machine tool, the secondary block is arranged, so that the clamping area can be increased; the position of the secondary block can be moved based on the area of a workpiece, so that the clamping power is increased, and the clamping stability is improved, and as a result, the workpiece processing accuracy is improved.
Description
technical field [0001] The invention relates to the field of numerical control equipment, in particular to a machining fixture for a numerical control machine tool. 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. CNC machine tools better solve complex, precise, small-batch, and multi-variety workpiece processing problems, and are flexible and high-efficiency automatic machine tools. In the process of processing the workpiece, it is necessary to use the fixture to clamp it. The fixture is a device used to fix the processing object in the process of manufacturing machinery or mechanical parts so that it occupies the correct position to accept construction or testing. However, the existing In the process of clamping the workpiece, the fixture in the technology has a limited clamping position. For some larger workpieces, the clamping force is not enou...
