  • Patent number: 8950987
    Abstract: A slip ring is accommodated in a ram 34. The slip ring includes a fixed portion 72 having a feed element connected to a power source and a movable portion 73 electrically connected to the feed element. The movable portion 73 includes a contact 75 for supplying electricity to a spindle unit 100 and an electric device of a spindle head 118. After determining the position of a saddle 32 in a Y-axis direction and the position of a table in an X-axis direction, the position of the spindle head 118 about a B-axis is determined. Then, the ram 34 is moved along the Z-axis direction with the spindle unit 100 revolved about the C-axis, and, with a non-rotational cutting tool 170 attached to the spindle unit 100, a hole is bored in a workpiece W on the table.

  • Patent number: 7062999
    Abstract: The object of the invention is to provide an inverted vertical lathe comprising a device for replacing collets automatically, and having a detector for detecting that the collet has been gripped correctly. A chuck 400 mounted on a headstock 40 grips a collet 500 in a replaceable manner via a tapered bore 430 provided to the end thereof. A collet end face eccentricity detector 600 comprises a detecting member (sensor) 610 fixed to the end of an arm 630. The detecting member 610 detects the eccentricity of the end face 510 of the collet 500 in a contactless manner. A variation pattern of the eccentricity occurring when each collet 500 is gripped correctly by the chuck 400 on the main spindle is detected in advance, and this pattern is compared with the variation pattern of the eccentricity detected by the present detection, and thus, whether or not the collet has been gripped correctly is detected.

  • Patent number: 6325646
    Abstract: A power plug assembly houses a plug in such a manner so that the plug is lifted up when required. The plug is always biased in a direction so that it is housed due to the force exerted by a first resilient member. When the plug is pivotally moved to some extent, first and second engagement parts are structured to engage with each other so that the plug is retained in a state ready to be plugged into an AC outlet. When the plug is pulled out from the AC outlet, a user may release the engagement of parts so that the plug is automatically housed in a space due to the resilience of the first resilient member.
