Preferably, also comprise spanner group grip block; Described Spring balancer is located on described work table and is positioned at the top of described work piece holder, described slide rail is vertically fixed on described work table and is positioned at the below of described Spring balancer, on described spanner group grip block linking springs balancer and do rectilinear motion up or down along described slide rail under the effect of described Spring balancer; Described electric torque spanner group is fixed on described spanner group grip block.In the utility model, select the Spring balancer of 3 ~ 5kg, with easy to use.
Preferably, described electric torque spanner group is provided with operating grip, and described operating grip is used for starting described electric torque spanner.
Preferably, described electric torque spanner group is provided with three cover electric torque spanners.
What preferably, described slide rail was selected is contract type line slide rail.Bolt fastening system described in the utility model is by the position relationship size between each bolt of calculating part to be processed, by the installing hole that is related to each electric torque spanner in dimensioned electric torque spanner group, use contract type line slide rail (micron order-walking depth of parallelism 3um) to be connected with spanner group grip block simultaneously, guaranteed the linearity that whole electric torque spanner group slides up and down, also guaranteed the perpendicularity of electric torque spanner group and part to be processed, avoided causing actual screw-down torque data inaccurate because of angular deviation.
In the utility model, on the workbench of work table, work piece holder is installed, in work piece holder inside, be provided with part pneumatic jacking mechanism simultaneously, electric torque spanner group is installed above work piece holder, by Spring balancer and contract type line slide rail, coordinate and allow electric torque spanner group slide up and down, during use, workman puts into part in work piece holder, push handle, electric torque spanner group comes downwards to lower dead center travel switch, circuit triggers electric torque spanner group is moved simultaneously, tighten the many groups bolt on part, and the torsion information of each electric torque spanner is outputed on information display screen, the show state of workman's observed information display screen can be judged the qualified or bad of current Assembly part.After the locking assembling process of whole bolt finishes, Spring balancer automatic lifting electric wrench Zu Yuqixing line slide rail mechanism resets.
The beneficial effects of the utility model are: the utility model bolt fastening system, can realize the automatic tightening of bolt, effectively eliminate the impact of extraneous factor on moment of torsion accuracy, monitor the locking state of each bolt simultaneously, prevent bolt neglected loading, also reduced labor strength when being reduced to original 1/3 man-hour.
