A torque tool to apply torque to a subsea component with a remotely operated vehicle (ROV) includes a housing, a socket drive to rotate within the housing, and a latch mechanism. The latch mechanism includes a latch to move with respect to the housing between an engaged position to engage the subsea component and a disengaged position to disengage the subsea component. The latch mechanism further includes a biasing mechanism to bias the latch from the engaged position towards the disengaged position, and/or an electric motor to move the latch from the disengaged position towards the engaged position.

A setting torque tool to tighten a screw or a similar fastener to a target torque is disclosed. The torque tool comprises a main body with a housing and a drive shaft, which is firmly attached to the housing to transfer a torque. The drive shaft has a connection area, to which a drive can be connected. An adapter for an operating tool rotates together with the housing and the drive shaft to transfer the torque, Sensor measure and evaluate the torque transferred. A release mechanism, which is arranged in the housing, releases the torque tool upon reaching a target torque.

Tooling systems and methods may be employed for installing a plurality of visually similar threaded fasteners to a plurality of assemblies. Each of the assemblies may have one or more threaded mating surfaces configured to receive different types of threaded fasteners, e.g., formed of different materials. The tooling system may include a tool(s) having a drive surface configured to install a threaded fastener by relative rotation of a gripping feature of the fastener with respect to a corresponding mating thread, each tool having a sensor disposed adjacent the drive surface and configured to detect a presence of the first material when a gripping feature of the one of the threaded fasteners of the first fastener type is positioned on the drive surface. The tooling system may also include a controller configured to determine the type of the selected threaded fastener based upon the sensor.

The present invention relates to an operation parameter regulation unit (50) for use with a bolting system having a plurality of networked electrically powered torque tools (10, 11) and/or drive portions of torque tools (10, 11) for simultaneous tightening of industrial threaded fasteners (40), the operation parameter regulation unit (50) including: a processing unit (53); an output unit (51) an input unit (52) an activation unit (55) for activating operation units and/or drive portions of torque tools (10, 11); and a control unit (54) for controlling operation parameters (41) of each of the plurality of networked electrically powered torque tools (10, 11) and/or drive portions of torque tools (10, 11) to maintain a difference between the operation parameters (41) within a predetermined value.

A fastening system for fastening a fastener to a workpiece, includes a movable carriage on which the workpiece is placed, a coordinate detection unit configured to detect a position of the fastener temporarily tightened onto the workpiece as coordinates in a coordinate system of the movable carriage, a storage device configured to store the coordinates detected by the coordinate detection unit, and a retightening device configured to determine a position of the fastener based on the coordinates stored in the storage device and retighten the fastener that is at the determined position.

The disclosure provides a method, device and equipment for monitoring screwing. The method for monitoring screwing comprises: obtaining an air pressure value in an air supply line; the air supply line being used to supply air to a pneumatic screwdriver to trigger the pneumatic screwdriver to perform a screwing operation; determining a target monitoring value according to the air pressure value; wherein the target monitoring value comprises at least one of: an initial air pressure value when the pneumatic screwdriver starts performing the screwing operation; a lower air pressure limit value when the pneumatic screwdriver performs the screwing operation; a working time of the pneumatic screwdriver for performing the screwing operation; judging whether the target monitoring value conforms to a corresponding predetermined range value and obtaining a judgment result; determining, based on the judgment result, whether the pneumatic screwdriver performs the screwing operation properly.

In a fastening device for fastening a bolt, a male thread is formed on a side surface of a bolt head part, and a part to be engaged is formed on a top surface of the bolt head part. The fastening device includes a bit having a tension rod having a rod female thread part, and an engaging part installed inside the tension rod and engaging the engaged part, the bit causing the bolt to rotate where the engaged part and engaging part are engaged; a supporter surrounding the tension rod in the circumferential direction such that the lower end part thereof protrudes below the lower end part; a sensor for sensing vertical compression force acting on the supporter; a first motor for causing the bit to rotate about the axis; and a second motor for causing the tension rod to rotate about the vertically extending axis.

A release mechanism for an electronically triggered torque tool to tighten a screw or a similar fastener triggers at a target torque. The release mechanism comprises a drive body and a main body, which rotate around a common axis to transfer a torque. A locking mechanism couples the drive body and the main body to transfer a torque. Measuring and evaluating means to measure and evaluate the torque transferred are provided, whereby a signaling device activates the locking mechanism to decouple the drive body from the main body upon reaching a target torque.

A system and method for precisely applying threaded caps using a linear rotary actuator is provided. The method includes aligning the threaded cap with the threaded top of a container, soft landing the threaded cap in contact with the threaded top, aligning the ends of the threads, soft landing the threaded cap in contact with the threaded top, and snugging the threaded cap. The system includes a linear rotary actuator and a tool for driving and coupling to the threaded cap.

A method for estimating a clamp force obtained at tightening of a screw joint via a torque pulse sequence includes applying a primary torque pulse to rotate the screw joint in a tightening direction, measuring a torque level obtained by the primary torque pulse, applying a secondary torque pulse to move the screw joint in a loosening direction, measuring a torque level obtained by the secondary torque pulse, and calculating a difference between the torque level obtained by the primary torque pulse and the torque level obtained by the secondary torque pulse. The obtained clamp force is estimated from the difference between the obtained torque levels.
