Special-shaped part machining fixing device

Abstract

The utility model discloses a special-shaped part machining fixing device which comprises a main body unit, the main body unit comprises a machining table, a plurality of arc-shaped through holes are formed in the upper end of the machining table at equal intervals, and a plurality of T-shaped grooves are formed in the lower end of the machining table at equal intervals; the special-shaped part clamping device has the beneficial effects that the hydraulic telescopic rod can drive the first clamping block to move and enable the first clamping block to abut against the surface of a special-shaped part, then the lead screw is rotated, the first clamping block is clamped in the arc-shaped through hole, the first clamping block is clamped in the arc-shaped through hole, and then the special-shaped part is clamped in the arc-shaped through hole. A second clamping block can be driven by a lead screw to move downwards and abut against the upper end of the special-shaped part to clamp and fix the special-shaped part, a fixing block is pushed, so that a threaded rod slides in an arc-shaped through hole, and therefore the angle of a fixing assembly can be adjusted; therefore, special-shaped parts of different sizes and shapes can be stably clamped at different angles through the multiple fixing assemblies.
