Work improves production efficiency.
Preferably, each workpiece fixed bit includes at least two connecting hole and 2 location holes, connecting hole and positioning
Hole stagger setting.
Preferably, the positioning device is fixed on bottom plate, including a bearing, it is provided with towards two and supports on bearing
Through hole between plate, through hole are stepped hole, and mandril has been penetrated in through hole, and mandril is radially arranged along workpiece Inner arc.
Preferably, bearing side is provided with hand-screw, by hand-screw fixed mandril after mandril positioning.
Preferably, the left end of mandril is the matched positioning head of concave arc slot with workpiece outer surface, have among mandril
One boss, spring left end are contacted with boss right side, and spring right end is contacted with the step surface in through hole, and end is equipped on the right side of mandril
Lid, end cap right side are equipped with nut.
Compared with prior art, the utility model has the beneficial effects that：The upper end of workpiece is fixed on top plate, positioning device
Workpiece lower end is positioned, when workpieces processing arc surface, the both ends of workpiece obtain positioning support, ensure that processing
Precision；Several workpiece are processed simultaneously, improve production efficiency.
