摘要： A variable torque-rate test point for the performance testing of rotary tools for threaded fasteners comprises a screw-threaded bolt (1) having a moment of inertia comparable to that of a bolt to be tightened using the rotary tool. The bolt (1) is tightened in the test joint against a torque-rate adjustment device (6) which can be adjusted to simulate a hard or a soft joint. The adjustment device (6) comprises a washer portion (7) beneath the bolt head (4), at least one spring beam (8) extending from a reaction point (9) radially outwardly of the bolt (1), and a pivotal bearing member (10) or other pivot at a mid portion of the beam (8). The beam (8) flexes as it extends in cantilever over the pivot point, and that flexure can be adjusted to vary the torque-rate of the test joint by varying the distance between the pivot point and the rotary axis of the bolt (1).

摘要： The invention provides a variable torque-rate test joint for the performance testing of rotary tools for threaded fasteners. In a typical test routine a nut is repeatedly tightened by the tool and after each tightening the nut must be released and run back to its start position. The invention provides a means for rapidly releasing the pressure on the tightened nut so that it can be run back quickly and easily. The variable joint is supported by a reaction surface that is the operative face of a piston and cylinder assembly seated on a shoulder fast to a shank of the threaded fastener. A hydraulic control is provided for the piston and cylinder assembly including means for hydraulically extending the piston from the cylinder to a fixed maximum extension which defines a test position of the reaction surface, and means for hydraulically retracting the piston back into the cylinder to remove the pressure from the nut at the end of the test. During tightening the piston is extended and preferably hydraulically locked.

摘要： An electronic click wrench comprises a handle for applying torque through a shaft to a working head. The shaft includes torque sensing means for calculating the torque applied to a workpiece by the working head, and a trigger mechanism for sending a haptic feedback to a user by triggering a small movement of the handle relative to the working head when a set point torque is reached. The trigger mechanism comprises a permanent magnet that is normally anchored by magnetic attraction to a pole piece so as to resist separation when a force is applied through the handle, and an electromagnetic means actuable to reduce or cancel that magnetic attraction so as to permit separation of the pole piece and permanent magnet, thus generating the haptic feedback. Operation of the electromagnet may oppose the flux of the permanent magnet through the pole piece. Alternatively operation of the electromagnet may divert the flux of the permanent magnet away from the pole piece.

摘要： A torque applying tool such as a nutrunner or torque wrench incorporates torque sensors responsive to strain in a shaft mounting an output square drive head the strain being measured as it exists immediately adjacent the drive head. The shaft is a hollow quill shaft an outer diameter of which is splined to receive a torque drive input at a location axially spaced from the drive head. A central shaft extends from the drive head centrally up the quill shaft and a flexible cantilever beam is mounted between a cranked end of the central shaft as it extends out of the quill shaft and the corresponding end of the quill shaft. One or more strain sensing transducers, preferably S.A.W. devices, are mounted on the cantilever beam to detect flexure of the beam, and the resulting output signal is passed through an inductive or capacitive coupling for transmission to a CPU and display.
