Turning machine fixture for motor assembly

The utility model discloses a fixture, and particularly relates to a turning machine fixture for motor assembly, which is characterized by comprising hydraulic cylinders (2), slide grooves (3), sliders (4) and compression rings (5). The sliders (4) are in 'L' shapes, the lower portions of the sliders are mounted in the slide grooves (3), one end of each slider (4) is a pressure head (6), a piston of each hydraulic cylinder (2) is connected with the corresponding slider (4), the compression rings (5) are disposed among the sliders (4) and a work piece (7) and fastened to the pressure heads (6) tightly, and the slide grooves (3) are in 'T' shapes. The turning machine fixture has the advantages that the fixture guarantees no gap in axial direction of workpieces so as to prevent the workpieces from being collided during turning, further the clamping means of hydraulic power and mechanical screw self-locking is adopted, and accordingly the turning machine fixture is reliable and safe in clamping, high in efficiency and high in automation level.
