[0045] Specifically, the electric control system 2 comprises an industrial computer 201 and a servo driver 202, the industrial computer 201 and the servo driver 202 are installed in the inside of the mobile cabinet 1, the industrial computer 201 and the servo driver 202 are electrically connected with a keyboard and mouse 501, a touch display 502 and a hand control box module 503, the power supply module 6 is electrically connected with the industrial computer 201, the servo driver 202, the keyboard and mouse 501, the touch display 502 and the hand control box module 503, and the industrial computer 201, the servo driver 202, the keyboard and mouse 501, the touch display 502 and the hand control box module 503 are powered through the power supply module 6.

[0046] Specifically, during use, the measured torque sensor 402 is connected with the sensor base 3002, and the measured torque sensor 402 is fixed on the sensor base 3002, after the fixing is completed, the output end of the standard torque wrench 401 is inserted into the measured torque sensor 402, and the other end of the standard torque wrench 401 is clamped between the two counterforce arms 303, before the standard torque wrench 401 is clamped between the two counterforce arms 303, according to the length of the standard torque wrench 401, the worker can manually adjust the position of the sliding block 302 on the guide rod 301, when the sliding block 302 is adjusted to the appropriate position, the sliding block 302 drives the counterforce arm 303 to move to the specified position, so as to adapt to the placement of different lengths of the standard torque wrench 401, after the placement is completed, the power supply module 6 is started, and the whole system and the measured torque sensor 402 are normally operated.

[0048] As shown in Figure 1 - Figure 3 As shown in the figure, the mobile cabinet 1 is provided with a display interaction system, the display interaction system comprises a touch display 502, the touch display 502 is installed on the mobile cabinet 1 through screws, the inside of the mobile cabinet 1 is provided with a keyboard and mouse 501, and the outside of the mobile cabinet 1 is provided with a hand control box module 503.

[0049] Specifically, during the torque calibration process, the torque information collected by the sensor base 3002 is displayed through the touch display 502, the system is interacted through the keyboard and mouse 501, and the starting and stopping of the servo motor 3004 and the speed are controlled through the hand control box module 503.

[0050] Specifically, during the detection process, after the standard torque wrench 401 is placed, the servo motor 3004 is started to drive the lead screw 3003 to rotate. The lead screw 3003 drives one end of the swing rod 3001 to translate on the lead screw 3003 during rotation. The swing rod 3001 twists the sensor base 3002 during translation, drives the sensor base 3002 and the measured torque sensor 402 to rotate to generate a certain torque, and collects torque information through the sensor base 3002 under the condition that the measured torque sensor 402 generates a certain torque. The torque data collector integrated in the sensor base 3002 collects the generated torque information. After the collection is completed, the servo motor 3004 is adjusted to continue rotating or pause to calibrate the measured torque sensor 402.

[0051] The technical solutions in the embodiments of the present application have at least the following technical effects or advantages: compared with the prior art, in the present application, the servo motor 3004 drives the lead screw 3003 to rotate, the swing rod 3001 twists the sensor base 3002 during rotation of the lead screw 3003, and the calibration of the measured torque sensor 402 or the standard torque wrench 401 can be displayed step by step during the twisting of the sensor base 3002. In the calibration process, the number of weights and the loading method are no longer limited, the loading speed is improved, and the calibration efficiency is improved.

[0052] Embodiment two, considering that the two rod-shaped counterforce arms 303 will move up and down between the two counterforce arms 303 due to the gradually increasing torsion of the standard torque wrench 401 during the limiting process of the standard torque wrench 401, which will cause instability, to solve the above technical problem, the technical solutions are as follows:

[0053] As shown in Figure 6 , the counterforce arm 303 is rectangular, and a plurality of positioning grooves 304 are formed on the outside of the counterforce arm 303 in the long direction. The positioning grooves 304 of the two rectangular counterforce arms 303 are oppositely arranged at the opening positions.

[0054] Specifically, during use, a plurality of positioning grooves 304 are formed on the outside of the two counterforce arms 303. The positioning grooves 304 can be used to clamp and limit the standard torque wrench 401. In the clamping and limiting process of the standard torque wrench 401, the standard torque wrench 401 can avoid the change of the stress direction due to the increase of the torsion, and the standard torque wrench 401 can avoid the shaking and instability between the two counterforce arms 303.

[0055] Further, the positioning groove 304 is integrally formed with a flexible wear-resistant rubber 305 inside.

[0056] Specifically, the elastic wear-resistant rubber 305 allows the larger standard torque wrench 401 to deform when it is inserted into the positioning groove 304, enabling the slightly larger standard torque wrench 401 to be smoothly inserted into the positioning groove 304. After being inserted into the positioning groove 304, the elastic wear-resistant rubber 305 can also increase the friction between the standard torque wrench 401 and the elastic wear-resistant rubber 305, further reducing the up-and-down wobbling of the standard torque wrench 401.

[0057] The technical solutions in the above embodiments of this application have at least the following technical effects or advantages: Compared with Embodiment 1, in this embodiment, the standard torque wrench 401 can be locked and limited by the square reaction arm 303 in conjunction with the externally opened positioning groove 304. During the locking and limiting process, the instability caused by the increased stress due to the standard torque wrench 401 being locked between the two reaction arms 303 is avoided.

[0058] Example 3

[0059] Considering that during use, because the elastic wear-resistant rubber 305 is soft, the increased torque during the engagement of the standard torque wrench 401 can cause displacement of the standard torque wrench 401, which further affects the torque correction, this application proposes the following technical solution to address the aforementioned technical problems:

[0060] like Figure 7 As shown, a triangular abutment plate 306 is fixedly connected to the side of the elastic wear-resistant rubber 305 away from the positioning groove 304.

[0061] Specifically, during use, when the standard torque wrench 401 is inserted into the positioning slot 304, the two triangular abutment plates 306 on the upper and lower sides will engage with the standard torque wrench 401. Because the triangular abutment plates 306 are triangular in shape and are inclined as a whole, after the side in contact with the standard torque wrench 401 abuts against the standard torque wrench 401, the obtuse angle end of the triangular abutment plate 306 away from the standard torque wrench 401 will be supported on the rigid part of the reaction arm 303, forming a lever. When the standard torque wrench 401 is subjected to force and moves to the left and right, the support point formed by the obtuse angle end will drive the other two ends of the triangular abutment plates 306 to further abut and limit the standard torque wrench 401, further reducing the phenomenon of movement of the standard torque wrench 401.

[0062] The technical solutions in the embodiments of the application have at least the following technical effects or advantages: compared with the second embodiment, in the embodiment, when the standard torque wrench 401 is clamped between the two triangular abutting plates 306, the two triangular abutting plates 306 form a support point with the counterforce arm 303, and further abut and limit the standard torque wrench 401 in the case that the standard torque wrench 401 moves under force, so that the phenomenon of excessive movement of the standard torque wrench 401 in the overall calibration process is avoided.

[0063] Embodiment four,

[0064] The utility model further provides a kind of full-automatic torque sensor calibration system, comprising: industrial computer 201, level conversion module, power control module, touch display 502, keyboard mouse 501, adjustable counterforce device, standard torque wrench 401, servo driver 202, servo motor 3004, mechanical transmission mechanism, abnormal protection device, measured torque sensor 402;

[0065] Wherein, industrial computer 201 and servo driver 202 are used for the control of entire system and the processing of data, judge current calibration state, output servo motor 3004 control signal;

[0066] Wherein, mechanical transmission mechanism and adjustable counterforce device are used for receiving the control signal loaded by industrial computer 201 and servo driver 202, the output torque of servo motor 3004 is transmitted to measured torque sensor 402, and standard torque wrench 401 is calibrated;

[0067] Wherein, standard torque wrench 401 and abnormal protection device are used for detecting actual torque value applied on measured torque sensor 402, and compared with the output of measured torque sensor 402, to obtain calibration result;

[0068] Wherein, touch display 502, keyboard mouse 501 and hand control box module 503 block are used for loading process display and signal man-machine interaction;

[0069] Wherein, level conversion module and power control module are used for power supply to each component.

[0070] Specifically, before calibration detection, the product model, product range, product number and accuracy grade of the standard torque wrench 401 are obtained, and after the calibration personnel confirm, the basic information of the detected torque instrument is added in the load setting control, including product name, product model, product number, submission unit, product range, product accuracy and calibration point number. After all the setting information is completed, the system automatically calculates the standard torque points that need to be calibrated according to the product range and the calibration point number, and displays them at the corresponding positions. After the calibration personnel confirm the standard torque points, the system completes the load preparation, selects the calibration direction, and clicks the start load button. Then, the system performs the pre-loading step according to the requirements of the JJG557-2011 Standard Torque Instrument Verification Regulation, automatically loads to the maximum range of the detected sensor and keeps for 30 seconds. After the time arrives, the system automatically unloads until the standard torque wrench 401 is not stressed, indicating that the unloading is completed. After waiting for 30 seconds, the pre-loading operation is continued, and the three-cycle loading process is completed.

[0071] Further, after starting the step of step-by-step calibration of the measured torque sensor 402, the system loads according to the first calculated standard torque point. The servo system loads the measured torque sensor 402 according to the pre-set loading curve, ensuring that the detected measured torque sensor 402 is loaded to the standard torque point without impact. When the standard torque value changes by less than ±0.03% within 10 seconds, it is considered to have reached the standard torque value. At this time, the system emits a "drip-drip" sound and pops up the first measured torque input dialog box. At this time, the measured torque sensor 402 torque value is filled in, and the completion is clicked to enter the second standard torque point calibration. The calibration process is the same as the first standard torque point calibration, and the calibration of the maximum range standard point is completed. After the calibration is completed, the system automatically unloads to zero and keeps for 30 seconds. Then, the system emits a "drip-drip" sound and pops up a zero return torque input dialog box. After the calibration personnel input the measured torque sensor 402 zero torque value, the system completes the first calibration process and starts the second calibration.

[0072] Further, the system repeats the calibration process twice to complete the second and third calibrations. After the three calibrations are completed, the system automatically calculates the detected value of the current calibration direction, and the calculation result includes the zero return error, repeatability and relative error. Clicking the save button can save the current direction record.

[0073] Further, after completion, another calibration direction is selected, the system is automatically reset to the current parameters, and a standard torque calibration point is generated, the calibration process is consistent with the first calibration direction process, after calibration is completed in both directions, the system automatically stores and generates a detection report. The calibration personnel can view the detection data and calibration report of the detected torque sensor in the search interface. The search interface reserves a query condition box, and the condition query can be performed according to date, number, model and the like. The search interface reserves a delete control, the data to be deleted is selected, and the corresponding record can be deleted by clicking delete.

[0074] The preferred embodiments of the utility model are merely used for limiting the utility model, and the utility model can be changed and varied for those skilled in the art. Any modification, equivalent replacement, improvement and the like within the spirit and principle of the utility model should be included in the protection scope of the utility model.
