摘要： Provided is an apparatus for detecting a failure in holding a tool of a machine tool that includes, in each of a plurality of tool holding mechanisms in a tool magazine, a locking member provided to have different self-displacement positions for a case where a tool is held at a proper held position between tool gripping portions of a pair of holding arms and a case where the tool is held with deviation from the proper held position, and that detects a holding failure state of the tool in the tool holding mechanism by detecting the position of a detection target portion that moves integrally with the locking member with a predetermined detector provided in the machine tool. The apparatus makes it possible to effectively prevent a risk of a breakdown of and damage to the machine tool.

摘要： Provided is a gripping method including: a phase matching step of matching tool relief grooves of a contact metal member and track grooves of a constant velocity universal joint component with each other in phase; a measuring step of measuring phase differences between the track grooves of the constant velocity universal joint component and a female spline of the constant velocity universal joint component; a matching step of matching, based on a result of the measuring step, a stopper with a recessed portion of the female spline having the smallest phase difference and gripping the constant velocity universal joint component by a collet chuck. Under a state in which the constant velocity universal joint component is gripped by the collet chuck, the contact metal member holds the constant velocity universal joint component.

摘要： A communicator in one aspect of the present disclosure includes a connector, a communication circuit, and a communication controller. The connector is electrically coupled to an electric working machine. The communication circuit performs wireless communication. The communication controller cyclically transmits operational information without specifying a recipient via the communication circuit in response to an operating mode of the communication controller being set to an operation-transmission mode. The operational information indicates an operating state of the electric working machine.

摘要： A device for simultaneously measuring and adjusting the tool holding portion of a spindle. The device has a body defining a datum surface providing a magnetic portion and an indicator portion. A socket extends from the magnetic portion, the socket dimensioned and adapted to receive and seat a first component of the tool holding portion on the magnetic portion. A compressible indicator tip extends in an outward-biased manner from the indicator portion, wherein a distance from the distal end of the indicator tip and the indicator portion of the datum surface is displayed along the body.

摘要： Systems and methods for intelligent tool detection are described. One embodiment includes placing a tool in a tool tray, and detecting a presence of the tool. Information associated with the presence of the tool is communicated to a processing system communicatively coupled to the tool tray. The tool is removed from the tool tray, and the removal is detected. Communication associated with the removal of the tool is communicated to the processing system. A distinction between information associated with the tool being present in the tool tray and information associated with the tool being removed from the tool tray is learned.

摘要： This unique and novel invention provides a custom data removal jig used to reliably, efficiently, and cost-effectively remove data from a handheld mobile computing device (“PC device”). The data removal jig comprises an open-box structure which provides one or more alignment features to assist with properly inserting the PC device within the data removal jig. Additionally, a pilot hole is provided by the securement structure. Once the PC device is inserted into the data removal jig, the pilot hole is substantially centered above the integrated flash memory chip on the particular PC device's motherboard which the data removal jig has been customized to accommodate. A power drill is used to precisely penetrate the PC device via the pilot hole and substantially isolate the damage to the integrated flash memory chip. Additionally, the securement structure also provides one or more braces that assist with restraining movement of the securement structure during the data removal process.

摘要： Proposed is a machine tool unit with a stator unit and a rotor unit which is rotatable about an axis of rotation, wherein the rotor unit comprises a spindle head with a tool-holding unit having a tool-clamping device, wherein a testing device is provided for testing the clamping state of the tool, the testing device having precisely one sensor head for sensory detection. To improve the precision, the sensor head is arranged at a fixed position on the stator unit in such a manner that it measures the distance to an end-side part of the spindle head rotating relative to the sensor head, wherein the testing device is designed to record a temporal/position-related sequence of at least two distance values and/or of at least two successive series of in each case at least two distance values, in order to determine an axial run-out error.

摘要： A power tool having multiple wireless communication states and a method of wirelessly communicating by a power tool. The power tool includes a motor, a battery pack interface that selectively receives a battery pack, a backup power source, and a wireless communication controller coupled to the backup power source and the battery pack interface. The wireless communication controller operates in a connectable state when coupled to a battery pack and transmits tool operational data to the external device and receives tool configuration data from the external device. The wireless communication controller operates in an advertisement state when the wireless communication controller is coupled to and powered by the backup power source. In the advertisement state, the wireless communication controller is configured to transmit the unique tool identifier. The external device may also display an indication of the communication state of the power tool.

摘要： A method of monitoring a tool clamping device mounted on a machine spindle, the clamping force of which tool clamping device is generated by a spring assembly which exerts a force in the direction of the clamping position on an actuating element actuating the clamping or the release of a tool or tool holder. In the method, the spring force and the displacement of the actuating element are continuously measured during the release and/or clamping of a tool or tool holder and recorded as functions of the time. These recorded functions are used to identify at least one parameter characteristic for the status of the tool clamping device. Based on the spring force and the displacement over time, a spring characteristic curve is plotted in the form of the spring force as a function of displacement, the analysis of which spring characteristic curve provides information about a number of characteristic parameters.
