VACUUM CHAMBER FOR EXHAUSTING EMPTY MATERIALS

摘要

PURPOSE: A vacuum chamber for ventilating a hollow member is provided to couple a bolt in an internal space of the vacuum chamber by driving a driver. CONSTITUTION: A vacuum chamber for ventilating a hollow member comprises an exhaust pipe, a driver device(121), and a mounting unit(133). The exhaust pipe connects an internal space of the vacuum chamber to a suction line of an external vacuum pump. The driver device includes: a tip corresponding to a bolt groove arranged in a hollow portion of the internal space; a rod being extended to the outside by penetrating through one side of the tip; and a rotary lever formed in an end portion of the rod to be integrated. The mounting unit fixes a hollow member(150) so that the bolt groove faces the tip of the driver.
