Intelligent automatic detecting device for thread missing of bracket

Abstract

The invention discloses an intelligent automatic detecting device for thread missing of a bracket. The device comprises hole detecting needles, a cylinder A, a cylinder B, a sliding block, a cylinderD, a feeding rail, a pushing block, a cylinder C, a probe, a blanking chute and a base, wherein the base is provided with a bracket and a slide rail; the hole detecting needles are provided with go-nogo gauges; the go-no go gauges are provided with stop sections, passable sections and guiding cones; the sliding block is provided with a pass area and clearance holes; the feeding rail is a rail formed by two parallel rectangular strip steel plates arranged at intervals; the pushing block is a steel component of a rectangular block shape; the probe is an active infrared-sensing electronic component; and the blanking chute is a steel sheet metal component. According to the technical scheme, the intelligent automatic detecting device for the thread missing of the bracket has the beneficial effects that by utilizing the characteristic that the bore diameter of a thread-missed hole is greater than that of an inner threaded hole and through the combination of the go-no go gauges, the probe, acomputer controller and the pneumatic components, the aims of reducing the working strength, eliminating missing detection, improving the efficiency and reducing the cost during the detection of thethread missing of the bracket are achieved.

Description

technical field [0001] The invention relates to an automatic inspection tool, in particular to an intelligent automatic detection device for missing thread of a bracket used for automatic detection of missing thread of a bracket. Background technique [0002] Explanation: The bracket is a kind of part used for automobiles. The bracket is provided with two threaded through holes called inner screw holes. When producing the bracket, the inner screw holes are processed by tapping technology, and a large number of brackets are being processed. During the tapping process, there will always be the phenomenon that the internal screw holes miss the tapping, which is called missing thread; for this reason, the prior art adopts the method of manual visual inspection to carry out full inspection of the missing thread one by one on the bracket, and select the bracket with missing thread Rework; manual visual inspection, high work intensity, easy to fatigue, after which it is necessary t...
