Clamping device with adjustable workpiece machining angle

Abstract

The invention relates to a clamping device with an adjustable workpiece machining angle. A bottom plate and a back plate are rotationally connected, the bottom plate is fixed to a machine tool, the bottom plate and the back plate can achieve one degree of freedom, then a rotating disc capable of rotating relative to the back plate is arranged on the back plate, a plurality of rotating disc pin holes are evenly formed in the rotating disc along the circumference, the rotating disc serves as a main ruler, each rotating disc pin hole corresponds to one angle after being aligned with a back plate pin hole in the back plate, angle adjustment of the rotating disc on the back plate can be achieved by inserting positioning pins into the back plate pin holes and the rotating disc pin holes, and therefore adjustment of two free angles is achieved, secondary clamping in the part machining process is avoided, the machining precision is improved, meanwhile, the machining efficiency can be improved, the structure is compact, adjustment is convenient and fast, the vast majority of adjustment requirements can be met, and technical guarantee is provided for improving the effective machining rate of equipment, saving the cost and the like; five-face machining can be achieved through one-time clamping and multi-time angle adjustment, and meanwhile the purchase cost of lengthened tools is reduced.

Description

technical field [0001] The invention belongs to the technical field of small workpiece processing, and in particular relates to a clamping device with adjustable workpiece processing angle. Background technique [0002] Precision machining environment for small workpieces and light chips, such as graphite or non-ferrous metal CNC (numerical control), EDM (spark machine), WEDM (wire cutting) processing, etc. Since this kind of process basically belongs to special processing, the equipment is generally 3-axis equipment, there are many types of small workpiece structures, the adjustment before processing is cumbersome, and the adjustment time is long, especially for complex special-shaped structure workpieces, there is no benchmark for secondary clamping or space angle adjustment Holes and faces can be used, but positioning and processing cannot be performed after the process is switched. It is difficult to find an adjustment tool that meets the process requirements on the mar...
