Loose head stock for automatic lathe
专利汇可以提供Loose head stock for automatic lathe专利检索，专利查询，专利分析的服务。并且PURPOSE: To obtain a loose head stock for an automatic multiple lathe whose piping is made easy, by providing an adjusting and thrusting device of a tail spindle independently from the loose head stock and supplying oil pressure or air pressure to a fixed portion which is unrelated to indexing motion of the loose head stock.
CONSTITUTION: The first stopping part 8 is provided to the rear end of each of loose head stocks 7 and the second stopping part 12 is provided at the rear end of a tail spindle 9 which is rotatably supported by the loose head stock. Pressure oil pipe a
1 and air pipe b
1 , which open into a front and rear chambers of a cylinder respectively, are provided in a piston rod 17. Pressure oil pipe a
2 and air pipe b
2 , which open into a cylinder 18, are provided in a piston rod 21. The pressure oil pipes and air pipes are separately communicated to their respective pressure sources and the piping of each of the oil and air pipes is thus simplified.
