台をそれぞれ示している。In the drawing, reference numeral 10 denotes an air introduction hole provided above the liquid level L of the lubricating oil filled therein, and an air conduit communicated with an air supply source 12 through a pressure regulating valve 11. 13 is connected so that air at a pressure slightly higher than the atmospheric pressure, for example, at a pressure of about 1.02 kg / cm 2 is introduced into the gear box 2. In the drawing, reference numeral 14 denotes the gear box 2 and the table 3
Reference numeral 16 denotes a seal member provided at a joint 15 of the work, and 16 denotes a work mounting table.

内部が正圧をなしている。In the gear box 2 constructed as described above, air having a pressure slightly higher than the atmospheric pressure is constantly introduced from an air supply source 12 through a pressure regulating valve 11.
The inside has a positive pressure.

防がれる。For this reason, the hydraulic cylinder 4 is first actuated to slightly raise the table 3 in order to position the portion to be processed of the work (not shown) facing the processing machine, so that the joint 15 between the table 3 and the gear box 2 is moved. Has a slight gap. However, since air having a slightly higher pressure than the outside is introduced into the inside of the gear box 2 as described above, even if the cutting fluid adheres around the gear box 2, the joint 15 Therefore, the cutting fluid does not flow into the lubricating oil, so that the generation of rust caused by the mixing of the cutting fluid into the lubricating oil can be prevented.

できる。 As described above, according to the present invention, air slightly higher than the atmospheric pressure is always introduced into the gear box of the rotary jig, so that the table is rotated before the table is rotated. Even if this is raised, it is possible to prevent the cutting fluid around the gear box from flowing into the inside, emulsifying the lubricating oil, and causing rust on the internal equipment. Moreover, with the connection of the air conduit,
Lubricate the connection between the table and gearbox, respectively.
Because it is located above the surface,
Supply lubricating oil to the lifting mechanism and rotating mechanism
Not only can they be smoother,
Ensure that lubricating oil does not leak out from the connection
it can.
