7 is a reference device in the preset type torque wrench calibration automation system according to an embodiment of the present invention - a graph showing the output trend of the torque value.

First, the lowest measurable point of the torque wrench 100 is approximately 10 ~ 100Nm, and calibration can be performed by 10% intervals. Depending on the setting using the integrated control unit 800 (refer to FIG. 4 ), each measurement point and the repeatability of the overall flow may be set.

For example, in the operation at each measurement point, the set value adjustment of the torque wrench 100 is set in the first motor 310, then the second motor 410 is operated and the output value of the reference unit 210 is It is output with the trend shown in FIG.

The operation of the torque wrench 100 at the set value is within the range of detecting a sudden change in the '-' direction while drawing a curve in the '+' direction as shown in the graph of FIG. 7 . Immediately after the change in the '-' direction, the second motor 410 rotates in the reverse direction and returns to the initial position, the first motor 310 operates to set the next measurement point of the torque wrench 100, and again the second motor ( 410) may be operated to perform a calibration experiment. In this way, the calibration experiment of the entire section for the torque wrench 100 can be completed.

However, through repeated calibration experiments, a malfunction was found in the system using the first and second motors 310 and 410 in the vicinity of 0 to 30% of the torque wrench 100 . In other words, when the output value of the reference unit 110 comes out in the '-' direction, the second motor 410 should operate in the reverse direction of the rotation direction. There was a problem that could cause the damage of (100).

For this reason, in the relationship between the '-' value among the output values of the reference unit 210 and the operating time (time), an advantageous 'inverse (-) slope' value that can be processed by the integrated control unit 800 is not output, so that the second motor It was found that the operation of (410) was not properly controlled.

In order to solve this problem, the present invention additionally applies the cushion support part 460 . The cushion support part 460 uses the elastic repulsive force of the plurality of elastic members 467 when the alarm part 140 is operated at a low setting value of the torque wrench 100 to instantaneously the body part 130 of the torque wrench 100. push the In this case, it is possible to maximize the 'slope of the output value in the reverse (-) direction' of the reference unit 210 . For this reason, even at a low setting value of the torque wrench 100, the operation error of the second motor 410 can be solved by making the shape of the section '③④' of FIG. On the other hand, the user can appropriately adjust the constants of the elastic support block 430 and the plurality of elastic members 467 constituting the cushion support part 460 according to the standard of the torque wrench 100 .

As described above, according to the configuration and operation of the present invention, the calibration of the preset wrench type torque wrench can be performed in an automated manner, and the torque amount can be adjusted and measured.

And, according to the configuration and operation of the present invention, it is possible to maximize the operability of the torque wrench alarm unit at a low measurement point to make the output value of the reference device in the torque wrench automatic calibration system consistent. Accordingly, it is possible to reduce the failure of the torque wrench and solve the error of the torque wrench automatic calibration system. In addition, there is an advantageous technical effect of being able to easily and easily perform a more accurate calibration of a preset type torque wrench in an automated manner.

As described above, the present invention has been described with reference to the illustrated drawings, but the present invention is not limited by the embodiments and drawings disclosed in the present specification. It is obvious that variations can be made. In addition, even if the effects of the configuration of the present invention are not explicitly described and described while describing the embodiments of the present invention, it is natural that the effects predictable by the configuration should also be recognized.
