Problems solved by technology

Although this clamping method is simple and easy to implement, it is found in the actual processing process that the cut part of the workpiece, due to the influence of its own weight and high-pressure water spray, will easily cause the part to shift when the part is about to end cutting, resulting in the cutting hole and the workpiece. surface squareness error

Abstract

The invention discloses an electrospark wire-electrode cutting machining combined clamp. The electrospark wire-electrode cutting machining combined clamp comprises a platform, an installation base and a fixing mechanism; and the installation base is fixedly installed on the platform, a V-shaped jaw is installed on the installation base, and the fixing mechanism is fixedly installed on the platform and used for exerting an abutting force on the side face of the installation base. By means of the combined clamp, a workpiece is stably clamped through the V-shaped jaw, the platform and the installation base are in sliding fit connection through a guide rail and guide groove structure, and the clamping positioning accuracy of the workpiece is increased; the installation base and the platform can be freely adjusted, and the universality of the combined clamp is improved; and meanwhile, the fixing mechanism is used for auxiliary clamping positioning on the workpiece, and the workpiece clamping machining stability is improved.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a combined fixture for electric discharge wire cutting. Background technique [0002] Wire-cut EDM belongs to the category of special processing, and is generally not used in mass production. In actual processing, general-purpose fixtures are often used. At the same time, the parts processed by wire-cutting are usually through-hole parts, which have special requirements for the working space. When cutting parts by slow wire cutting, the interference problem caused by the close distance between the upper nozzle and the surface of the workpiece must also be considered. Therefore, when the parts are processed by wire cutting, the selection of fixtures is relatively limited, especially when the cantilever fixture is used. When the processing is nearing the end, it is more likely to turn around, resulting in a large verticality error between the cutting surface of the pa...
