Detection device and method for nail leakage in machining process

Abstract

The invention relates to a detection device for nail leakage in a machining process. The detection device comprises a driving motor and a transmission rotary shaft, wherein a torsion sensor is arranged between the driving motor and the transmission rotary shaft; the detection device further comprises a programmable controller which is in communication connection with the torsion sensor; a driving motor is electrically connected with the programmable controller and is controlled by the programmable controller to operate; the driving motor is used for driving the transmission rotary shaft to carry out a riveting work on a component; the torsion sensor is used for feeding a detected torque back to the programmable controller; the programmable controller is used for carrying out integral calculation, capturing an instant torque peak value and comparing and judging whether a nail leakage phenomenon or an insufficient machining force condition exists at present or not; and manual observation is not needed, and the device completely depends on self-detection of the device. The detection device is not influenced by environment factors and can be applicable to any machined component; and the whole structure is simple, and the cost is low.

Description

technical field [0001] The invention relates to the technical field of detection of missing rivets in processing, and more specifically relates to a detection device and method for missing processing rivets. Background technique [0002] A rivet is a common part used to connect and fasten two or more parts. It is usually nail-shaped and has a cap at one end. In the existing rivet processing industry, the detection of missing rivets mostly relies on manual detection. There is a certain probability of missing nails by eye observation; while infrared, laser, etc. rely on the principle of light to detect missing nails, which are greatly affected by environmental factors and the shape of processed objects, and are not suitable for diversified processing environments. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a processing missing nail detection device that does not require manual observation and relies entirely o...
