Problems solved by technology

[0005] The hitherto known methods for checking and calibrating such mounting wrenches are either so complex that they require the mounting wrench to be sent to the manufacturer and are therefore time-consuming and expensive, or they, for example, use so-called torque angle gauges for angle indication check, does not have the required precision

Embodiment Construction

[0027] Figures 1a to 1c In stereo view ( Figure 1a ), side view ( Figure 1b ) and top view ( Figure 1c ) shows a first embodiment of the inspection device according to the invention.

[0028] The inspection device has a base plate 1 which is configured with a semicircular region 1a and a first straight region 1b which connects the two ends of the semicircular region 1a to one another. The second straight area 1c is configured at right angles to the first straight area 1b such that it connects the middle area of ​​the first straight area 1b with the apex of the semicircular area 1a.

[0029] On the underside of the base plate 1 there is provided a holding block 9 on which the testing device can be clamped, for example, in a vice (not shown in the figure) and can be fixed in this way.

[0030] On the upper side of the base plate 1 opposite the bottom side, a cantilever 2 is supported such that it can surround an axis B arranged in the second rectilinear region 1c at the m...

Abstract

The invention relates to a device for checking an installation wrench (5), which has a tool carrier (5a) and a drive element (5b), comprising a fixing device (4a), which is designed to fix the tool carrier (5a), a holding device (2), which is designed to hold and fix the drive element (5b) and can be pivoted along a circular arc (1a), and at least two stops (6, 8), which are arranged along the circular arc (1a) and are designed to stop the holding device (2) in a respectively defined position.

Description

technical field [0001] The invention relates to a device and a method for checking a mounting wrench, in particular a mounting wrench with integrated torque and angle measuring means. Background technique [0002] Mounting wrenches are increasingly used for tightening or tightening threaded connections at predetermined torques, in addition to or in place of a conventional measuring device for measuring and displaying the torque applied to a threaded joint. Integrated angle measuring device for angle indication, which measures and displays the angle through which the mounting wrench has been turned. The angle through which the setting wrench is turned is measured, for example, by a gyrometer integrated in the setting wrench. [0003] With this mounting wrench several threaded connections can be produced by pre-tightening the threaded connection with a slight torque and then turning the mounting wrench by a defined angle of rotation. Moving within tighter tolerances when tig...
