Method and system of recording locking positions of bolts through data acquisition technology

Abstract

The invention discloses a method of recording the locking positions of bolts through the data acquisition technology. The method comprises the following steps of S1, arranging a locating device in theposition corresponding to each bolt to be fastened; S2, arranging a trigger device capable of triggering the locating devices on a portable tightening machine; S3, triggering the corresponding locating device immediately after the tightening machine is placed in the position of the bolt to be tightened, and resetting the locating device until the tightening machine gets away from the bolt to be tightened; and S4, combining real-time torque information of the portable tightening machine and trigger information of the locating devices in time sequence to judge whether a locking result is qualified or not. Thus, through the method of recording the locking positions of the bolts through the data acquisition technology, torque data of the tightening machine can be matched with the bolts on site to realize the process tracing of the bolt positions and the torque value during the bolt tightening process, the manual recording time is omitted, and the production efficiency is improved. The invention further discloses a system of recording the locking positions of the bolts.

Description

technical field [0001] The invention relates to the field of production and processing, in particular to a method and system for recording bolt locking positions using data acquisition technology. Background technique [0002] Although the degree of automation of production is getting higher and higher, there are still many places that require manual operation. For example, in the frame assembly link in the field of automobile production, there are still many bolts that need to be tightened manually with a portable tightening gun. [0003] The current portable tightening machine provides a wide range of peripheral equipment support and communication interfaces, and has a built-in large-capacity memory, which can provide historical data query of locking results. The portable tightening gun has a WiFi function, can be connected to the field network, and communicate with the host computer, which can satisfy real-time control, and realize the transmission of real-time locking re...

AI Technical Summary

Problems solved by technology

The portable tightening gun has a WiFi function, can be connected to the field network, and communicate with the host computer, which can satisfy real-time control, and realize the transmission of real-time locking results and make judgments and records on the locking results: However, the current portable tightening gun The machine can only provide the torque data for each tightening, and the operator needs to manually confirm whether the tightening of the bolts is up to standard. It can be seen from the historical data of the machine that a certain bolt has not been tightened. However, since there is no position information of the bolt, it is impossible to quickly locate the untightened bolt. We can only speculate based on the time point and find the untightened bolt for retightening. solid

[0004] Chinese patent CN103786127B-discloses a method for recording the tightening of bolts. It takes pictures of the surrounding area when each bolt is tightened, and then relies on the surrounding environment shown on the photo to assist in locating the position of the fastening bolts. However, the photos The amount of data is very large, and the requirements for on-site data transmission and storage space are relatively high.
