therefore, by obtaining the information of the assembling parts to be assembled, the information can be compared with the preset information of the assembling parts to match different requirements of the torque wrench 4.
Since the torque wrench 4 may require different torque requirements for the same component, the mounting component information includes the torque requirements for all mounting points.
The second matching module is used for matching the torque ranges of all the torque wrenches 4 on the bearing table 2 according to the assembly strategy to obtain the torque wrench 4 matched with each assembly point;

Whether the set of all the middle accurate intervals in the step A contains the torque requirements of all the assembly point locations or not means that 10 assembly point locations and 6 middle accurate intervals are assumed to exist, and if the torque requirements of the 10 assembly point locations are in the set formed by the 6 middle accurate intervals, the set of all the middle accurate intervals contains the torque requirements of all the assembly point locations; if the torque requirement of any one assembly point is not in the set formed by the 6 middle accurate intervals in the torque requirements of the 10 assembly point positions, no, that is, the set of all the middle accurate intervals does not contain the torque requirements of all the assembly point positions.
Similarly, the same determination method is also adopted to determine whether all the sets of middle adjustment sections contain the torque requirements of all the assembly point locations, and only the set of middle accurate sections used for determination is replaced by the set of middle adjustment sections.
And if the determination result is no, increasing the value of the adjustment value n, and multiplying by 1.5 times each time, where the adjustment value n may be preset, for example, 3, and if the middle accurate interval is set to be 26 to 34n, the adjusted middle adjustment interval is 23 to 37n, that is, the interval is widened by using the adjustment value n.

Referring to fig. 6, the historical usage includes historical overload times x and historical usage times y, and sorting the torque wrenches 4 according to the historical usage of the torque wrenches 4 to obtain a frequency sequence, including:
g-21, generating an actual number of times t of each torque wrench 4 according to the historical overload number x and the historical use number y of each torque wrench 4, wherein the actual number of times t = y (1000 + x ^ 3)/1000;
g-22, sequencing the torque wrenches 4 according to the actual times t of the torque wrenches 4 to obtain a frequency sequence.
Specifically, the actual number of times t is sorted from large to small, for example, the historical overload number of a certain torque wrench 4 is 5 times, and the historical use number of times y is 500 times, and then the actual number of times t =500 +(1000 +5^ 3)/1000 =562.5 times, it can be understood that as the historical overload number of the torque wrench 4 increases, the actual number of times increases accordingly, and the accuracy change sorting of the torque wrench 4 can be better simulated according to the above formula because the overload number has a loss on the accuracy of the torque wrench 4, and further, the accuracy change sorting of each torque wrench 4 can be reflected through the frequency sequence.
The adjusting of the central adjustment interval set of each assembly point according to the historical use condition of each torque wrench 4 includes deleting the central adjustment intervals except for the lowest frequency sequence in the central adjustment interval set. That is, of the plurality of middle adjustment intervals of the middle adjustment interval set corresponding to one assembly point, only the middle adjustment interval with the lowest frequency sequence is reserved as the adjusted middle adjustment interval.
It can be understood that the adjusted middle adjustment interval is necessarily small in precision change in the original middle adjustment interval set; and if the middle adjusting interval set corresponding to one assembly point position only comprises one middle adjusting interval, taking the only middle adjusting interval as the adjusted middle adjusting interval.

when a worker puts a correct torque wrench 4 into the wrench placing groove 5, the second prompting unit controls the induction prompter 3 on one side of the wrench placing groove 5 of the torque wrench 4 corresponding to the next assembly point in the assembly sequence to send out prompting information, and when the worker puts an incorrect torque wrench 4 into the wrench placing groove 5, the first prompting unit controls the induction prompter 3 on one side of the wrench placing groove 5 to send out alarm information; the second prompting unit controls the induction prompter 3 on one side of the wrench placing groove 5 of the torque wrench 4, which is correspondingly matched with the next assembly point position in the assembly sequence, not to send out prompting information.
The operator can be gradually reminded to take the corresponding torque wrench 4 in sequence according to the assembly sequence of the assembly strategy; and if the operator does not take the tool vehicle according to the prompt sequence, the information of the assembly part and the timestamp information are recorded, or the tool vehicle can be opened only by using the identity information or the verification information when the operator uses the tool vehicle, so that the information of the operator is recorded, and the follow-up tracing is facilitated.
In addition, the torque wrench 4 with the data uploading function can be adopted, when the torque wrench 4 is used, the acquired torque data can be uploaded to the management platform, the management platform can compare the acquired data with the corresponding standard data to judge whether the applied torque meets the requirement, the problem of poor assembly caused by improper operation of an operator is avoided, and the accuracy and the standardization of the assembly process are further realized.
