Embodiment Construction
[0055] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0056] refer to Figure 9 , the present invention provides a threaded fastening component and a threaded fastener in-position detection method and system, which is used to solve the existing problem of using the set torque to judge whether the threaded fastener is fastened in place and cannot find the threaded fastener The problem of the situation where the position is not in place is also used to solve the problem of high cost of manual inspection. The invention can automatically identify the risk of wrong installation, timely find out that the threaded fasteners are not fastened in place, and give an alarm in time, which improves the degree of automation, reduces manual inspection, reduces labor costs, reduces investment in tooling equipment, and reduces equipment cost. The in-position detection method and system for threaded fasteners of t...

The invention relates to an in-place detection method and system for a thread fastener. The method comprises the following steps that the thread fastener is used for being in threaded connection witha butt-jointed thread connecting hole so as to realize fastening connection of two parts; before the threaded connection, a convex point is arranged on the inner wall of the thread connecting hole; inthe threaded connection process, the rotating angle value of the thread fastener from the convex point to the set torque is obtained; and the obtained rotating angle value is compared with the set value, if the rotating angle value is smaller than the set value, it is indicated that the thread fastener is not fastened in place, and an alarm is sent for prompt. According to the method and the system, the angle, passing from the convex point to the set torque, of the thread fastener is acquired, whether the thread fastener is fastened in place or not is judged according to the angle, then the phenomenon that the thread fastener is not fastened in place can be found in time, moreover, the alarm is sent in time for prompt, so that the manual checking step is omitted, the labor cost and the checking tool cost are saved, and the automation degree is improved.
Description
technical field [0001] The invention relates to the field of mechanical structure connection detection, in particular to a method and system for in-position detection of a threaded fastening component and a threaded fastener. Background technique [0002] As a common connector, bolts are usually used to fasten two parts. Such as figure 1 As shown, the first part 11 and the second part 12 are fastened and connected by bolts 13, combined figure 2 As shown, the first part 11 is provided with a threaded connection hole 111, and the second part 12 is provided with a through hole 121. The through hole 121 is aligned with the threaded connection hole 111, and the bolt 13 is passed through the through hole 121. and threaded connection with the threaded connection hole 111 , a bushing 14 is sleeved at the through hole 121 , and the bolt 13 passes through the bushing 14 and is threaded connected with the threaded connection hole 111 . For the threading process of bolt 13, please r...
