Description

Technical Field

[0001] The invention relates to the field of precision measurement technology, and in particular to a locking full-process precise measurement system. Background Art

[0002] With the continuous development of the manufacturing industry, the assembly quality of products has become increasingly important. In order to ensure that key parameters such as the locking force and preload force of the product during the assembly process meet the design requirements, it is necessary to accurately measure the locking force and preload force during the product assembly process.

[0003] Although the locking full-process measurement system in the prior art can measure the locking force and pre-tightening force, the measurement is not accurate enough at that time, and it is impossible to obtain the various states required for the entire locking process, and it is impossible to provide real-time feedback on the full-process locking measurement results, which will lead to the inability to achieve efficient and reliable locking. Summary of the invention

[0004] In response to the above technical problems, the present invention proposes a precise measurement system for the entire locking process, including a full-process measurement spectrum, a precise measurement control information set, and a measurement status evaluation system; the full-process measurement spectrum includes the start-up of the main locking system, the start-up of the auxiliary locking system, the full-speed movement stage, and the locking cut-off stage; the precise measurement control information set includes wear and life control, drive conduction and inertia control, reduction device and motor turns, and temperature compensation; the measurement status evaluation system includes fault indication, time limit, abnormal starting current, and abnormal locking current.

[0005] Furthermore, there are time delays and peak shifts in the startup of the main locking system and the auxiliary locking system. The time element and the deformation element of the locking device at startup are used as references to accurately calculate the state and information set of each locking system reaching the startup point.

[0006] Furthermore, the full-speed motion stage is: using the rotation speed element of full-speed flipping and the alternating control element of rotation speed adjustment under the timeline to calculate and lock the full-speed stage spectrum information.

[0007] Furthermore, the locking cut-off stage is: after receiving the cut-off point information, using the cut-off current as a control element, and the time element and the cut-off deformation amount as calculation basis elements to calculate the locking cut-off state information.

[0008] Furthermore, the precise measurement and control information set includes: information on wear and life control, drive conduction and inertia control, reduction device and motor turns, and temperature compensation; measurement of locking time and deformation state information, prediction of locking static and dynamic angle information, prediction of locking dynamic frequency information, and participation in closed-loop control of the entire locking process.

[0009] Furthermore, the measurement status evaluation system is to: measure the status information of fault indication, time limit, abnormal starting current and abnormal locking current, warn the upper layer to lock the abnormal situation of the whole process, and control each actuator to respond to corresponding protection and processing measures.

[0010] The beneficial effects of the present invention compared with the prior art are as follows: the present invention proposes a precise measurement system for the entire locking process, which can use elements such as time, deformation, and rotation speed throughout the locking control during the entire execution process of the locking system, and at the same time use the corresponding source information such as wear and temperature to combine and accurately measure the control information set, and perform a fitting comparison of information such as predicted angles and frequencies under the entire locking process, and feed back to the locking control system, which can accurately obtain the various states required for the entire locking process, and through the measurement state evaluation system, the full-process locking measurement results can be fed back in real time, and the upper layer processes the locking control system in real time based on the measurement results, to achieve efficient and reliable locking.
