Associated control device and method for screw hole detection and oiling of automobile door lock

Abstract

The invention discloses an associated control device and method for screw hole detection and oiling of an automobile door lock. On the working surface of a detection box body, a positioning column isfixed to the working surface, a detection column is inserted into the detection box body from the working surface, the bottom of the detection column is connected with a locking base fixed into the detection box body through elastic parts, a probe rod is inserted horizontally into the detection box body and fixed with the detection column, a guiding groove A allowing the probe rod to move vertically is formed in the detection box body, a sensor is located below the initial height of the probe rod and fixed with the detection box body, the diameter of the detection column is smaller than that of a threaded light hole formed in a lock body of the door lock and larger than that of a threaded hole after tapping of the threaded light hole; and an oiling opening communicating with an oiling pipeline is formed in the working surface, and a control system is associated with the sensor and the oiling opening through signals. On the same associated control device, the logical functions of two associated processes of screw hole detection and oiling can be completed on the lock body of the automobile door lock, whether threaded holes are assembled in the lock body can be detected timely and automatically, and the mistake-proofing action is effectively achieved.

Description

technical field [0001] The invention relates to a threaded hole detection and oiling process of an automobile door lock production line, in particular to a correlative control device and method for threaded hole detection and oiling of an automobile door lock. Background technique [0002] With the lean development of the automobile industry, the error-proof requirements for the production of automobile door locks are also getting higher and higher. Most of the existing door lock production lines have assembly automatic detection and functional intelligent detection during and after assembly, but they cannot automatically detect whether there are missing tapped assembly threaded holes in the door lock body, and there is no threaded hole identification and detection equipment, and manual The reliability of identification and detection is low, so there is a risk of missing the security inspection of the assembly threaded hole of the door lock lock body, which causes the assemb...
