Background
The electric gun for tightening the screw is usually preset with a tightening torque, so that the screw can be conveniently and rapidly tightened with a rated torque; however, after the tightening electric gun is used for a long time, because of abrasion, slippage and other reasons, the preset tightening torque is not the actual tightening torque of the electric gun, that is, the tightening torque displayed on the tightening electric gun deviates from the actual tightening torque and exceeds the allowable range, and at this time, the tightening electric gun needs to be calibrated. Therefore, there is a need for a device for detecting the actual tightening torque of a tightening gun to determine whether it requires calibration.

The utility model aims to overcome the defects of the prior art, and provides a tightening electric gun calibration device which is used for clamping and tightening an electric gun body and a bolt to be tested, and comparing the deviation of a torque display value and a torque detector value of the electric gun through the work of tightening the electric gun to judge whether the tightening electric gun needs to be calibrated.
The technical scheme adopted for solving the technical problems is as follows: the tightening electric gun calibration device comprises a bottom plate fixed on the workbench, wherein a torsion column and a fixing frame are fixed on the bottom plate, and the torsion column is in threaded connection with a bolt to be tested; the bolt to be tested can be connected with the tightening electric gun through the torque detector, and the fixing frame can be clamped and fixed on the anti-rotation plate of the tightening electric gun body.
Further, the bottom plate is provided with a rectangular groove, and the torsion column is provided with a side flattening section embedded in the rectangular groove and fixedly connected with the bottom plate through a screw.
Further, a transition sleeve is arranged between the bolt to be detected and the moment detector.
Further, the fixing frame comprises two horizontal bars fixed on the bottom plate, and the cross section of the top beam of each horizontal bar is U-shaped.
The beneficial effects of the utility model are as follows: the tightening electric gun calibration device comprises a bottom plate fixed on the workbench, wherein a torsion column and a fixing frame are fixed on the bottom plate, and the torsion column is in threaded connection with a bolt to be tested; the bolt to be tested can be connected with the tightening electric gun through the torque detector, and the fixing frame can be clamped and fixed on the anti-rotation plate of the tightening electric gun body. According to the utility model, the bolt to be tested is screwed again, the tightening torque is obtained respectively at the torque detector and the tightening electric gun, the numerical deviation of the torque detector and the tightening electric gun is compared, if the deviation is within the allowable range, the tightening electric gun does not need to be calibrated, and if the deviation exceeds the allowable range, the tightening electric gun needs to be calibrated, and the device can also be used for checking whether the tightening electric gun is well calibrated.

Detailed Description
The utility model will now be described in further detail with reference to the drawings and the specific embodiments, without limiting the scope of the utility model.
As shown in fig. 1, the tightening electric gun calibration device of the embodiment comprises a bottom plate 1 fixed on a workbench, wherein a torsion column 2 and a fixing frame 3 are fixed on the bottom plate 1, and the torsion column 1 is in threaded connection with a bolt 4 to be tested. During operation, the hexagonal nut of the bolt 4 to be tested is clamped into the torque detector 6, then the output end of the tightening electric gun 7 is clamped with the torque detector 6, and in order to prevent the tightening electric gun 7 from rotating, an anti-rotation plate 71 is fixed on the body of the tightening electric gun 7 and clamps the anti-rotation plate 71 on the fixing frame 3; starting the tightening electric gun 7, when the tightening electric gun cannot rotate, reading the values of the torque detector 6 and the tightening electric gun 7, wherein the value of the torque detector 6 is the tightening torque of the bolt 4 to be tested, is also the actual torque of the tightening electric gun 7, compares the numerical deviations displayed by the tightening electric gun 7 and the torque detector 6, and if the deviation is within an allowable range, the tightening electric gun 7 does not need to be calibrated, and if the deviation exceeds the allowable range, the tightening electric gun 7 needs to be calibrated; similarly, when the tightening gun 7 is calibrated, the calibration fixture of the embodiment may also be used to check whether the tightening gun 7 is calibrated.
The torsion column 2 is connected with the bottom plate 1 through a screw, in order to reduce or even eliminate the torque born by the screw, the bottom plate 1 is provided with a rectangular groove 11, and the torsion column 2 is provided with a side flattening section embedded into the rectangular groove 11, so that the torque born by the torsion column 2 is directly transmitted to the side surface of the rectangular groove 11, namely, the bottom plate 1 bears the torque.
The torque detector 6 is usually a standard product, and the dimensions of the connectors at the two ends of the torque detector are not necessarily adapted to the bolt 4 to be tested and the tightening electric gun 7, so in actual operation, the torque detector 6 is in switching connection with the bolt 4 to be tested and/or the tightening electric gun 7 through the transition sleeve 5.
The fixing frame 3 comprises two horizontal bars 31 fixed on the bottom plate, and the cross section of the top beam of the horizontal bars 31 is U-shaped. The anti-rotation plate 71 fixed on the tightening gun 7 has a single plate and a double plate, when the single plate is clamped between the two horizontal bars 31, and when the double plate is clamped into the U-shaped notch of the top beam of the two horizontal bars 31 respectively. When the tightening electric gun 7 works, the reverse torque is large, the body of the tightening electric gun 7 is difficult to control by manpower to rotate, and meanwhile, the calibration tool of the embodiment is provided with the fixing frame to prevent the body of the tightening electric gun 7 from deflecting in order to better and accurately measure the torque.
Finally, it should be noted that the above embodiments are only for illustrating the technical solution of the present utility model, and not for limiting the scope of the present utility model, and although the present utility model has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions can be made to the technical solution of the present utility model without departing from the spirit and scope of the technical solution of the present utility model.
