    摘要： A production assembly tool for securing fasteners to a workpiece such as an automobile body. The production assembly tool of the present invention includes a housing which encases a motor, a transmission, a clutch mechanism and a control module. The control module controls the running and braking of the motor and prevents both over and under securing of a fastener caused by falsely detected tool clutch conditions. An improved clutch sensor switch is operatively associated with the control module for detecting clutch disengagement. The clutch mechanism is designed to drive the fastener until the clutch sensor switch detects clutch disengagement and signals the control circuit to stop drive and start braking. The production assembly tool further includes a system for ensuring accurate placement of the power tool motor in the power tool housing subsequent to motor servicing or repair. Further, an adjustment collar located in the tool nose allows selective access to a clutch adjustment mechanism of the tool located within the housing for torque level adjustment. In addition, the tool housing is covered by an integral, self-sealing non-marring overmold exterior. The overmold exterior allows a lubrication needle to be inserted through an aperture located beneath the overmold exterior. After the needle is removed, the overmold exterior subsequently self-seals, thereby preventing dirt from entering the interior of the tool housing and the applied lubrication from leaking.

    摘要翻译： 一种用于将紧固件固定到诸如汽车车身的工件的生产组装工具。 本发明的生产装配工具包括一个外壳，其包围电动机，变速器，离合器机构和控制模块。 控制模块控制电机的运行和制动，并防止由于错误检测到的工具离合器条件而导致的紧固件的过度和过紧。 改进的离合器传感器开关与用于检测离合器分离的控制模块可操作地相关联。 离合器机构设计用于驱动紧固件，直到离合器传感器开关检测到离合器分离，并向控制电路发出信号以停止驱动并开始制动。 生产装配工具还包括一个系统，用于在马达维修或修理之后确保电动工具电机在动力工具壳体中的精确放置。 此外，位于刀尖中的调节套环允许选择性地进入位于壳体内的工具的离合器调节机构以进行扭矩水平调整。 此外，工具外壳由一体式，自密封的非破损外覆模制外壳覆盖。 包覆模制外部允许润滑针穿过位于包覆模制外部下方的孔。 在取下针之后，包覆模制外部随后自密封，从而防止灰尘进入工具壳体的内部，并且所施加的润滑剂不会泄漏。

    摘要： The present invention is directed toward a shield assembly for a handheld tool device such as an angle grinder. The shield assembly is selectively repositionable with respect to the cutting tool. A lock mechanism secures the shield assembly in discrete rotational positions relative to the cutting tool. The shield assembly includes a guard member and a bumper member, and an alignment feature configured to align the relative positions of guard member and the bumper member, thereby positing the members in a predetermined relative orientation. With this configuration, the shield assembly is selectively repositionable via a “hands-free” mechanism that permits a user to adjust the position of the shield assembly by simply contacting the shield assembly against a work surface.

    摘要： A power driver may include a motor that rotates upon receiving an input current. A tool chuck may have chuck jaws to hold an accessory. The tool chuck may be coupled to the motor. A power take off mechanism may be connected between the motor and the tool chuck. The power take off mechanism may be adjustable into a CHUCK MODE to one of open and close the chuck jaws while the motor rotates. An electronic clutch may interrupt the input current to the motor if the power take off mechanism is in the CHUCK MODE and if the input current exceeds a trip value.

    摘要： A method for calibrating a power tool having a roller, a driver and a solenoid. The solenoid has a body and a rod and is coupled to the roller so as to be capable of selectively advancing the roller toward the driver. The method includes: locating the roller onto a predetermined portion of the driver; moving the body of the solenoid in a first direction until the occurrence of a first predetermined condition, the first direction being in a direction that causes the roller to be driven toward the driver; after the occurrence of the first predetermined condition, moving the body of the solenoid in a second direction opposite the first direction until the occurrence of a second predetermined condition and thereafter securing the body of the solenoid to inhibit further movement of the body of the solenoid.

    摘要： A power tool generally includes a housing and a motor assembly connected to a transmission assembly. The motor assembly and the transmission assembly are secured against rotation in the housing. A plurality of protrusions extends from a component of the transmission assembly. The power tool further includes an output spindle and a spindle lock assembly that connects the output spindle to the transmission assembly. The spindle lock assembly includes an anvil, an outer ring member and a plurality of roller members. The roller members and the protrusions are disposed between the anvil and the outer ring member. An indicator member extends from the outer ring member. A compliant member connects the outer ring member to an interior portion of the housing. A scale is connected to an exterior portion of the housing, wherein the indicator member moves relative to the scale to indicate a value of torque at the output spindle.
