Description

Technical Field

[0001] The utility model relates to the technical field of nut detection, in particular to a high-reliability automatic detection fixture for riveted nuts. Background Art

[0002] Nut threads are manually inspected using thread go / no-go gauges, which is not suitable for mass production and has certain reliability issues. In addition, cracks in the nut material itself cannot be judged by the naked eye, resulting in low inspection efficiency and poor inspection results.

[0003] After searching, the application with patent publication number CN203849433U discloses an automatic detection tool for armrest hinge nuts, including a fixing plate, above which a clamping cylinder and a nut detection cylinder are provided. The clamping cylinder and the nut detection cylinder are both connected to a two-hand start button, and the nut detection cylinder is also connected to an alarm button. This enables the car seat armrest hinge nuts to be detected quickly, thereby improving the efficiency of armrest hinge nut detection.

[0004] However, due to the setting of the fixing plate, the nuts need to be manually placed on the fixing plate for inspection, which has a low degree of automation, is time-consuming and labor-intensive, and is inconvenient for inspecting large quantities of nuts. At the same time, there are settings of a clamping cylinder and a detection cylinder. The nuts are tightened by the clamping cylinder and then inspected by the detection cylinder. The inspection effect is poor and the accuracy is low.

[0005] Therefore, we proposed a high-reliability automatic detection fixture for riveted nuts. Utility Model Content
