Detailed description of the invention
Below in conjunction with accompanying drawing 1, accompanying drawing 2, accompanying drawing 3, accompanying drawing 4, accompanying drawing 5, accompanying drawing 6, accompanying drawing 7, the present invention will be further described for accompanying drawing 8。
Assembly of the invention connection diagram as shown in Figure 1, this is installed to common pneumtic impact wrench 1 for the torque force device 2 of determining of pneumatic impact spanner, and sleeve 3 is arranged on torsion ring。Common pneumtic impact wrench thus can be made to possess the effect determining torsion。
Such as Fig. 2, Fig. 3, Fig. 4, shown in Fig. 5, this includes the cylinder 2.4 in cylinder barrel shaped of one end closing one end open for the torque force device 2 of determining of pneumatic impact spanner, central shaft 2.1, the supporter 2.3 of cylinder 2.4 opening it is installed on by holding screw, it is installed on the interior inner spring sheet 2.7 near blind end of cylinder 2.4, it is installed on the interior outer spring sheet 2.9 near supporter 2.3 of cylinder 2.4, described cylinder 2.4 blind end arranged outside has the square shaft 2.10 identical with wrench socket 3 square hole size, the inner hole wall of cylinder 2.4 is peripherally disposed several spine grooves, central shaft 2.1 is made up of the square hole shaft being connected with pneumtic impact wrench 1 and splined shaft, splined shaft is installed in cylinder 2.4 and one end is rotatably supported the other end and is rotationally connected with in cylinder 2.4 blind end axis hole by supporter 2.3。
The schematic diagram of Fig. 6, Fig. 8 respectively inner spring sheet 2.7 and outer spring sheet 2.9, inner spring sheet 2.7 and outer spring sheet 2.9 are the rectangular patch body with chamfered end, and chamfered end is arranged in cylinder 2.4 endoporus spine groove, and the other end is installed on splined shaft keyway。During use, size according to required torsion selects the quantity of outer spring sheet 2.9 and inner spring sheet 2.7 so that it is be set to the moment of standard。Owing to the length of inner spring sheet 2.7 is more than the length of outer spring sheet 2.9, so inner spring sheet 2.7 is for providing the spring leaf of high torque, outer spring sheet 2.9 is the spring leaf providing less moment of torsion。So specification and the quantity of cluster spring sheet can be facilitated moment of torsion as required。When starting working, pneumtic impact wrench 1 drives central shaft 2.1 to rotate, it is installed on central shaft 2.1 due to spring leaf and spring leaf chamfered end is arranged in cylinder 2.4 endoporus spine groove, so central shaft 2.1 rotation can drive torsion ring to rotate, torsion ring drives wrench socket 3 to rotate, and wrench socket 3 rotates with bolt or nut。
When the screw-down torque of bolt and nut reach regulation moment then, wrench socket 3 is subject to equal countertorque, now spring leaf place stress reaches the marginal value of its elastic deformation, due to elastically-deformable reason, spring leaf can disconnect from spine groove, thus central shaft 2.1 drives spring leaf can rotate relative to cylinder 2.4, in rotary course, spring leaf is owing to disconnecting from spine groove continuously thus realizing beating the sound of rattling away of cylinder 2.4。Operator hears sound, just quits work immediately。Now the moment of bolt just reaches the moment of regulation。
