摘要： A clamp apparatus used for machining a workpiece, such as a structural beam, includes a stationary clamp apparatus and a movable clamp apparatus. The stationary clamp apparatus clamps onto a first side or flange of the workpiece, and the movable clamp apparatus clamps onto another, generally opposite side of the workpiece. The movable clamp apparatus is capable of shifting position in the direction of the stationary clamp means. A pair of fastening mechanisms are positionably secured to the clamp apparatuses, for securing and positioning the workpiece with respect to the clamp apparatuses.

摘要： An exchange chuck for exchangeably mounting a tool shank adapted for mounting a tool such as drill or tap. The tool shank is inserted to and fastened in a mounting bore formed in a tubular portion of a spindle. A movable sleeve is received on the tubular portion for movement longitudinally thereof, and plural balls are provided to the tubular portion so as to be intruded into or receded from said bore with movement of the movable sleeve, said balls operating to engage with and prevent extraction of the tool shank when intruded into the bore. An ejector member is received in the bottom region of the bore and biased forwardly at all times by a coil spring for extruding the tool shank forwardly at the time of exchange operation of the tool shank. The forward outer periphery of the ejector member is formed with an undercut annular groove contiguous to an engagement step operating to engage with the radially inner surfaces of the balls to prevent accidental extraction of the ejector member in the forward direction.

摘要： The invention provides a turning type multi-spindle attachment used for mounting a plurality of drills or taps to a drilling or tapping machine. This attachment comprises a mounting cylinder fixed to the spindle quill of the drilling or tapping machine and a body positioned such that a turning position thereof is adjustable relative to the mounting cylinder, whereby a plurality of drills or taps are rotatably supported by the body. The position of the drills or taps is adjustable around the mounting cylinder by causing turning of the body relative to the mounting cylinder.

摘要： A collet chuck assembly used for the attachment of a tap to the spindle of a tapping machine is provided. A bore for insertion of the base end of the tap is formed in the lower portion of a cylindrical portion, and at least one O-ring is mounted on the inner wall of the bore such that it is open to view on the inner peripheral face thereof. With the O-ring, the tap is held in place so as to prevent it from slipping down, and is supported somewhat floatingly within the bore in the diametrical direction. The cylindrical portion is provided therein with a pair of locking faces for locking the prismatic portion of the tap in place so as to inhibit any turning thereof and with a pair of steps or a set screw for controlling the amount of insertion of the tap thereinto.

摘要： A multi-spindle head attachment in which a positively rotated main spindle gear is meshed with a plurality of intermediate gears which are, in turn, meshed with spindle gears fitted respectively onto spindles each adapted to grip a drill, a tap or the like. Further, one of the spindles can be located in the position where its axis is aligned with the center of axis of the main spindle gear. Disc-like interference preventing members for preventing interference between the intermediate gears and the spindle gears, are provided to the intermediate gears and/or the spindle gears. Each interference preventing member has a diameter slightly larger than that of its corresponding addendum circle of the intermediate gear or spindle gear, and therefore its outer peripheral surface protrudes from the addendum circle of each gear. A slight gap is formed between each interference preventing member and the end face of each gear.

摘要翻译： 一种多主轴头部附件，其中，主轴旋转的主轴齿轮与多个中间齿轮啮合，多个中间齿轮又分别安装在主轴上，主轴齿轮分别安装在主轴上，每个主轴适用于夹持钻头，龙头等。 此外，主轴中的一个可以位于其轴线与主轴齿轮的轴心对准的位置。 在中间齿轮和/或主轴齿轮上设有用于防止中间齿轮与主轴齿轮之间的干涉的盘状防干扰部件。 每个防干扰部件的直径略大于其中间齿轮或主轴齿轮的对应的齿顶圆的直径，因此其外周表面从每个齿轮的齿顶圆周突出。 每个防干扰构件和每个齿轮的端面之间形成微小的间隙。
