    摘要： A manually operated apparatus for removal and insertion of a tool holder to and from a tool pocket of a magazine includes two components--a multi-function insertion/removal tool, and a pivot bracket. The multi-function tool generally comprises an elongated bar having a tool holder removal element at one end and an insertion element at the opposite end. The removal element can constitute a known pry tool having a fork portion configured to facilitate insertion between the rim of the tool pocket and the underside of the circumferential flange of the tool holder. The insertion element of the multi-function insertion/removal tool comprises a pivot block and a pressure plate. The pivot block includes a pivot pin projecting therefrom that is configured for pivoting engagement within a channel defined in the pivot bracket. The pivot bracket is mounted to the housing of the tool magazine at a manually accessible location relative to the tool pockets with the open end of the channel facing away from the tool pocket. When the pivot pin of the insertion/removal tool is disposed within the channel of the pivot bracket, the pressure plate is situated over a portion of the circumferential flange of the tool holder when the holder is loosely disposed within the tool pocket. The elongated bar of the tool can be used as a lever arm to pivot the tool about the fulcrum point defined by the pivot pin and pivot bracket. As the elongated bar is manipulated, the pressure plate is pivoted downward, bearing against the circumferential flange of the tool holder with sufficient force to overcome the pocket spring force operating against the knob of the tool holder.

    摘要翻译： 一个手动操作的装置用于将工具夹具移出和插入到刀库的工具仓中并且从刀库的工具仓中插入，包括两个部件 - 多功能插入/拆卸工具和枢轴支架。 多功能工具通常包括细长杆，其在一端具有刀架拆卸元件，在相对端具有插入元件。 移除元件可以构成已知的撬装工具，其具有构造成便于在工具槽的边缘与工具架的周向凸缘的下侧之间插入的叉部。 多功能插入/拆卸工具的插入元件包括枢轴块和压力板。 枢转块包括从其突出的枢轴销，其构造成用于在限定在枢转支架中的通道内枢转接合。 枢转支架相对于工具袋安装在工具仓的壳体上，手动可接近的位置，其中通道的开口端面远离工具口袋。 当插入/移除工具的枢转销设置在枢转支架的通道内时，当保持器松动地设置在工具袋内时，压板位于工具夹具的周向凸缘的一部分上方。 工具的细长杆可以用作杠杆臂，以使工具围绕由枢轴销和枢轴支架限定的支点枢转。 当细长杆被操纵时，压板向下枢转，以足够的力抵靠工具保持器的周向凸缘，以克服针对工具架的旋钮操作的口袋弹簧力。

    摘要： The present invention involves a tool changer for removal and installation of tools in a machining center having a machine tool with a spindle for holding a tool disposed within the machining center frame. The tool changer comprises a tool rack having a plurality of locations for holding tools, and an arm structured and arranged to be movable between the plurality of locations and a position which is capable of accessing a spindle of the machining center. Each tool holding location farther comprises a fork, which has a plurality of prongs. The movable arm has two grippers and one of the two grippers is disposed at an angle of about 90° relative to the other of the two grippers. The movable arm also is associated with rotational, vertical, and horizontal movement mechanisms. The rotational mechanism includes a motor, a pulley associated with the motor, a belt attached to the motor and the pulley, and a gear wheel attached to the belt with a limit switch for sensing one of the locations on the gear wheel. The vertical mechanism includes a vertical shaft and a cylinder capable of moving the movable arm vertically. The horizontal mechanism includes a linear track and a cylinder capable of moving the movable arm laterally. The frame further includes an access door located proximate the tool holding locations and sized to allow for manual access to one of the tool holding locations. The access door also has at least one location for holding a tool. The tool changer further comprises a cylinder actuated door which allows for the arm to access the spindle.
