Tool for surface machining

Abstract

The invention provides a tool for surface machining and belongs to the field of numerically-controlled machine tool machining equipment. The tool comprises front and back locating assemblies, left and right locating assemblies and upper and lower locating assemblies, wherein the front and back locating assemblies can clamp two sides of a workpiece, and the back locating assembly can internally support the opened end of the workpiece while locating the workpiece, so that deformation of clamped two sides is avoided; the front locating assembly is driven by an oil cylinder to clamp the placed workpiece, the lower locating assembly supports the workpiece and the upper locating assembly compresses the workpiece. The tool provided by the invention can locate and clamp the workpiece in six directions, and is firm to locate and high in locating precision, and the machining precision is favorably enhanced.

Description

technical field [0001] The invention belongs to the field of numerical control machine tool processing equipment, in particular to tooling for surface processing. Background technique [0002] In the automobile manufacturing industry, there will be processing requirements for various shapes of parts, many of which are irregular in shape, and there is no suitable conventional fixture to meet the needs of the installation and positioning of the machining center. If other ordinary machine tools are used to cooperate with manual processing, and It will greatly reduce the processing accuracy and work efficiency, and affect the production. The processing positioning of the U-shaped workpiece is one of the problems. The commonly used U-shaped fixtures are to clamp the opposite sides of the U-shaped pipe respectively before processing the pipe. However, it is difficult to ensure that the pipe of the U-shaped pipe fitting does not deform, especially for a U-shaped pipe with a thin th...
