A kind of hydraulic fixture used on CNC machine center to drill holes on an oil pipe used in cars was introduced.Over-positioning was used to solve the problem that the rigidity of spindly pipe was bad,and the mechanical system and hydraulic circuit were designed.Clamping many workpieces each time and highly automatic hydraulic driving make it an effective fixture.
