20080209707 | Method for Attaining a Predetermined Clamping Force in Threaded Joints - METHOD FOR ATTAINING A PREDETERMINED CLAMPING FORCE IN THREADED JOINTS through the employment of a plurality of equations and graphs converted into digital data and applied to a system of intelligent monitoring, being part of a computer program or specific software dedicated to operate manual or automatic spindle machines, the needed parameters being measured at the axle of the equipment connected to the wrench that acts over a threaded fastener, such as a bolt, nuts or equivalent element during the fastening operation, the acquisition of the data for calculation and utilization the variable “torsion angle” θ, θ | 09-04-2008 |
20090260209 | SCREWING APPARATUS AND METHOD OF CONTROLLING SCREWING OPERATION - A screwing apparatus includes a support member having a horizontal support surface. A single urging member has an urging surface opposed to the support surface. The urging surface is set parallel to the support surface. A driving mechanism is configured to drive at least one of the support member and the urging member to move to change the distance between the support member and the urging member. Driver bits have the tip ends opposed to the support surface, respectively. The driver bits are driven to move toward and away from the urging surface. | 10-22-2009 |
20120073104 | Bolt preloading check system - A bolt system for indicating a level of preload of a bolt that is connectable to a subject to be fixed is disclosed The bolt system includes the bolt with a bolt head, a first sleeve attached to the bolt between the bolt head and the subject and a second sleeve attached to the bolt between the bolt head and the subject. The first sleeve is an inner sleeve and the second sleeve is an outer sleeve that fits around the first sleeve. One sleeve is longer than the other sleeve. When the preload is below a maximum value, the longer sleeve transmits the preload between the bolt head and the subject. When the preload is above the maximum value, the longer sleeve is compressed in such a way that both sleeves transmit the preload between the bolt head and the subject. | 03-29-2012 |
20120210552 | Position Make-Up Indicator System - A method is shown by which threaded pipe sections are connected to form a tubular joint having proper sealing positioning at proper make-up torque. A make-up stencil plate is manufactured for each specific size of pipe to be coupled at the specific taper and make-up loss of a given connection with very tight tolerance. The plate is placed on the pin pipe end of the connection. A dial indicator is placed on the outer surface of the pipe pin end with the indicator flush with the end of the stencil plate. Once the indicator is set to zero, the stencil plate is removed. Then a bucking unit or power tong is applied to the coupling. When the face of the coupling hits the tip of the indicator and the indicator is within the given tolerance, the operator stops the make-up process. | 08-23-2012 |
20130291358 | SYSTEM AND METHOD FOR MOUNTING A WIRE HARNESS WITHIN A VEHICLE INTERIOR - A cable tie for mounting a wire harness within a vehicle interior includes a mounting portion having an opening configured to receive a fastener for securing the cable tie to a support structure. The cable tie also includes a tie portion extending from the mounting portion. The tie portion is configured to wrap around the wire harness to secure the wire harness to the cable tie, and the tie portion is laterally offset from the opening along a direction substantially perpendicular to a longitudinal axis of the tie portion. | 11-07-2013 |
20140013564 | METHOD FOR TIGHTENING SCREW JOINTS WITH A HAND HELD POWER TOOL - A method for tightening a screw joint up to a predetermined target torque level (T | 01-16-2014 |
20140068909 | Torque Wrench and Method of Operating the Same - A torque wrench includes a hollow body, a clutch mechanism, a force-applying member, and at least one driving arm. The clutch mechanism is mounted in the hollow body. The force-applying member is pivotally mounted in the hollow body and has a first end against the clutch mechanism. The force-applying member also has a second end for the driving arm coaxially mounted at. Thus, the torque wrench can take the overall length of the force-applying member and the driving arm as a first moment arm, and the torque wrench is easy to storage due to the detachable driving arm. In addition, the torque wrench can be increased in length by mounting a driving arm which is a plurality of rods detachably assembled with each other. A method of operating the torque wrench includes mounting the clutch mechanism and the force-applying member in the hollow body, and mounting the driving arm at the second end of the force-applying member. The torque wrench can be increased in length by mounting a plurality of the driving arms. | 03-13-2014 |
20140090224 | TORQUE-APPLYING TOOL AND TORQUE CONTROLLER THEREFOR - A torque applying system includes a torque applying tool having a motor and rotating output spindle, a torque sensor that measures an instantaneous torque exerted by the output spindle during a fastening cycle, and a controller operatively connected to the tool to control the tool's rotational speed during the fastening cycle. The controller is programmed to control the tool's rotational speed to be [(τ | 04-03-2014 |
20150360354 | THREAD PROTECTOR DRIVE MECHANISM - A drive mechanism for installing thread protectors on threaded pipe ends having a servo motor, a housing, a shaft assembly, and a gripper with a plurality of jaws. The shaft assembly has a hollow shaft, rotationally mounted within the housing, and a solid shaft slidably mounted within the hollow shaft. The hollow shaft and solid shaft are coaxial and rotationally coupled. The gripper is mounted on the end of the solid shaft, outside of the housing, and is biased away from the housing. A sensor monitors the relative axial motion between the solid shaft and the hollow shaft. | 12-17-2015 |
20160375566 | TIGHTENING TOOL FOR COAXIAL CONNECTORS - A tool for tightening a coupling nut includes: a hollow shaft having a length, an outer diameter, and a thickness, the hollow shaft including a longitudinal gap extending between a first end and a second end of the shaft, the shaft being formed of a resilient material; and a plurality of faces located on an inner diameter of the shaft adjacent one of the ends, the faces arranged to receive a coupling nut. The dimensions and material are selected so that, when the faces of the tool engage a coupling nut and a torque is applied to the shaft below a preselected level, the faces maintain engagement with the coupling nut, thereby rotating the coupling nut, but when a torque exceeding the preselected level is applied to the shaft, the shaft deflects sufficiently that the faces slip relative to the coupling nut, thereby preventing rotation of the coupling nut. | 12-29-2016 |
