[0002] In order to monitor the force and torque of the product in the test bench, sensors are indispensable. Whether the force display of the sensor is consistent with the actual force will greatly affect the accuracy and reliability of the test results. At present, sensors are usually calibrated by the manufacturer. With the change of usage and environmental conditions, it is impossible to determine whether the sensor display is still consistent with the actual situation, which will affect the accuracy of the test result evaluation.

[0003] The offline torque sensor calibration tooling for which protection is requested in this application can compare the display data of the offline calibration sensor with the tooling bench sensor, so as to determine whether the tooling bench sensor is displayed correctly, thereby ensuring the accuracy of the test results. The comparative display analysis of the offline calibration sensor and the tooling bench sensor can determine whether the tooling bench sensor truly displays the actual situation. If there is a deviation, it can be compensated by software to ensure that the bench sensor display is consistent with the actual situation and the accuracy of the test results. In addition, the calibration tooling structure of the offline torque sensor is reasonably designed, and the calibration of the tooling bench sensor is convenient, accurate and fast, and is suitable for popularization and use.

DETAILED DESCRIPTION

[0013] The utility model is now described in further detail in conjunction with the accompanying drawings. The accompanying drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0014] For specific embodiment 1, please refer to Figure 1-2A calibration tool for an offline torque sensor, comprising a mounting seat 1, a bottom plate 2, a support plate 3, a top plate 4 and a lower connecting screw 15, wherein the bottom plate 2 is fixed on the mounting seat 1, the bottom of the support plate 3 is fixed on the bottom plate 2, the top of the support plate 3 is fixed with the top plate 4, the lower connecting screw 15 passes through the middle of the bottom plate 2, the top of the lower connecting screw 15 is fixedly connected to a tooling stand sensor 6 through a coupling 5, the tooling stand sensor 6 is fixedly connected to an offline calibration sensor 8 through a first connecting block 7, a force block 10 is placed on the top plate 4, an upper connecting screw 14 is fixed to the bottom of the force block 10, and the upper connecting screw 14 is fixed to the bottom of the force block 10. The connecting screw 14 passes through the top plate 4, and the bottom of the upper connecting screw 14 is fixedly connected to the offline alignment sensor 8 through the second connecting block 9. The lower connecting screw 15 is fixed to the bottom plate 2 through a locking nut 16. A rotating handle 11 is provided on the force block 10, and screw rotation holes 13 are provided on both sides of the force block 10. Locking screws 12 are provided in the screw rotation holes 13, and the locking screws 12 can fix the force block 10 on the top plate 4. Screws are provided on the first connecting block 7 and the second connecting block 9, and the screw rotation holes 13 are arc-shaped. The mounting seat 1, the bottom plate 2, the support plate 3 and the top plate 4 are made of stainless steel.

[0015] The utility model designs a calibration fixture for an offline torque sensor. During use, the calibration fixture for the offline torque sensor first fixes and connects the coupling 5, the fixture stand sensor 6, the first connecting block 7, the offline calibration sensor 8 and the second connecting block 9 in sequence, then fixes the bottom of the coupling 5 on the lower connecting screw 15, and fixes the lower connecting screw 15 on the base plate 2 through a locking nut 16, and then fixes the top of the second connecting block 9 to the bottom of the force block 10 through the upper connecting screw 14.

[0016] Then, the rotating handle 11 is rotated clockwise and counterclockwise to apply torque to the force block 10, and the torque is displayed by the display connected to the offline benchmark sensor 8. When the corresponding torque is reached, the force block 10 is fixed to the top plate 4 with the locking screw 12, and then compared with the torque value collected on the tooling bench sensor 6 to determine whether the two are the same. If the values ​​displayed by the two sensors are consistent, it means that the tooling bench sensor 6 can reflect the real situation in real time to ensure the accuracy of the test results; if there is a difference, it needs to be compensated in the software based on the corresponding difference, and the above method is used again to confirm whether the compensated tooling bench sensor 6 is consistent with the value of the offline sensor. The method of continuous compensation is used to ensure that the value of the tooling bench sensor 6 is consistent with the actual value of the offline benchmark sensor 8, and finally the accuracy of the test results is ensured. In short, the calibration tooling structure of the offline torque sensor is reasonably designed, and the calibration of the tooling bench sensor is convenient, accurate and fast, and suitable for promotion and use.

The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
