摘要： A chuck comprises: a chuck body attached to a spindle of a machine tool; master jaws attached to the chuck body along the normal of the chuck body and formed with T-shaped grooves extending along the length thereof; T nuts having tops and trunks, the tops being slidably fitted in the T-shaped grooves of the master jaws; gripping claws having work holding surfaces and grooves for engagement with the trunks of the T nuts; and eccentric shafts inserted into holes formed across the T nuts and the gripping claws and used for attaching the gripping claws to the T nuts. The holes extend across the T nuts and the gripping claws which are engaged with one another. The gripping claws have large reshaping margins at work holding surfaces thereof.

摘要： The jaw assembly includes a master jaw and an insert jaw. An engagement surface on the master jaw provides a mounting surface for the insert jaw. The master jaw is contoured to provide a minimum of mass opposite the mounting surface and opposite the engagement surface to minimize the total rotating mass when the jaw assembly is in operation. In operation, a force is applied substantially perpendicular to the engagement surfaces between the insert jaw and master jaw such that the engagement surface experiences the force rather than the insert fastener.
摘要翻译：钳口组件包括主钳和插入爪。主颚上的接合表面提供用于插入颚的安装表面。主钳具有轮廓，以提供与安装表面相反并且与接合表面相对的最小质量，以在夹爪组件运行时最小化总旋转质量。在操作中，施加大致垂直于插入爪和主钳之间的接合表面的力，使得接合表面经受力而不是插入紧固件。

摘要： A lathe chuck jaw assembly utilizes top jaws which have replaceable inserts mounted to their clamping faces. The inserts are used to provide a contact surface to hold a workpiece during machining. The contact surfaces of the inserts may be machined for matching a particular workpiece shape such as round stock, hex stock, square stock, or custom configurations. A boring ring is installed between the top jaws and rotated so that the inserts may be symmetrically machined. Alternatively, a polygonal insert blank having congruent sections which are joined with keys along their outer sides may be loaded in the lathe chuck and machined for a particular workpiece. A pad adapter base for supporting a hardened collet pad is also disclosed.

摘要： A jaw assembly for use with a lathe chuck which is rotatable about an axis and provided with at least two first cooperative mating portions circumferentially spaced apart about the axis. The jaw assembly includes at least two cylindrical bodies. Each body has a longitudinal axis, a cylindrical outer surface and first and second spaced-apart generally parallel outer planar surfaces disposed in planes generally perpendicular to the longitudinal axis and to the cylindrical outer surface. Each body is adapted to have at least three circumferentially spaced-apart workpiece-receiving cutouts therein extending through at least the outer cylindrical surface and the first planar surface. Each body carries second cooperative mating portions for mating with the first cooperative mating portions of the chuck to secure the body to the chuck so that the body rotates in an immovable manner with respect to the chuck. The bodies are mountable with respect to the chuck to rotate therewith in at least three different positions.

摘要： A top jaw system for securing a top jaw in position above a chuck on a milling machine, lathe or the like is provided. A protrusion extends upward from the chuck and is preferably attached to the chuck by rigid attachment to a jaw nut which is positioned in a common master jaw on the chuck. The protrusion has a pair of flat faces which extends upward and over the jaw nut to form acute angles with the jaw nut. A top jaw having a slot sized to receive the protrusion is placed over the protrusion. The top jaw has a pin aperture extending through the top jaw through the slot at a right angle to the protrusion when the top jaw is placed on the protrusion. When the top jaw is placed on the protrusion, an elongated pin having a pair of flat surfaces extending along its elongated axis is placed in the pin aperture. One of the flat faces of the protrusion is pushed into contact with one of the flat surfaces of the pin. This is preferably done by the movement of the master jaw by hydraulic means attached to the master jaw. When the master jaw is moved by the hydraulic device, pressure is applied to the contact between one of the flat faces of the protrusion and one of the flat surfaces of the pin. Because of the acute angle formed by the flat face, this pressure causes the protrusion to ride up over the pin raising the jaw nut into contact with the master jaw. Simultaneously, downward pressure is applied to the top jaw through the pin to clamp the top jaw onto the top of the master jaw.
摘要翻译：提供了一种用于将顶爪固定在铣床，车床等上的卡盘上方的位置的顶颚系统。突起从卡盘向上延伸，并且优选地通过刚性附接到位于卡盘上的公共主钳中的钳口螺母附接到卡盘。突起具有一对平面，其向上和向上延伸到钳口螺母上以与钳口螺母形成锐角。具有尺寸设置成容纳突起的槽的顶部颚放置在突起上。当上颚放置在突起上时，顶颚具有延伸穿过顶颚通过狭槽延伸的销孔，其与突起成直角。当顶颚放置在突起上时，具有沿其细长轴线延伸的一对平坦表面的细长销被放置在销孔中。突起的平坦面之一被推入与销的一个平坦表面接触。这最好是通过连接到主钳口的液压装置的主钳的运动来实现的。当主颚由液压装置移动时，压力施加到突起的一个平面和销的平坦表面中的一个之间的接触。由于由平面形成的锐角，该压力使得突起在上述销上升高，使得钳口螺母与主颚接触。同时，通过销将向上的压力施加到顶部夹爪，以将顶部夹爪夹紧到主颚的顶部上。

摘要： A collet chuck assembly is provided for accommodating workpieces of unusual shape and non-standardized sizes, as well as standard sizes. The assembly includes an insert configured to be firmly received into and held by standard sized collets. The insert has circumferentially spaced longitudinally extending radial slots forming jaws arranged to coact with a conventional collet for receiving and holding a workpiece. Preferably, at least the forwardmost portion of the insert body is comprised of a soft metal which may be easily machined, after the insert is received in the collet, for accommodating unconventionally shaped and sized workpieces.
