Embodiment 1

[0035] Embodiment one: with reference to attached Figure 2-4 As shown, a rapid detection method for the depth of countersunk holes of flat head screws,

[0036] Include the following steps:

[0037] A. Prepare a height gauge 1, inner diameter micrometer, outer diameter micrometer and standard tungsten steel ball 2;

[0038] B. Remove the burrs on the edge and orifice of the part 3, wipe off the oil on the surface, set the detection base plate 4, fix the height gauge 1, and clean the surface of the base plate 4;

[0039] C. Return the inner diameter micrometer and the outer diameter micrometer to zero respectively, and then measure the material thickness t and the bottom hole diameter d of the part 3 to be measured;

[0040] D. Based on the upper surface of the bottom plate 4, reset the height gauge 1 to zero, then place the countersunk head of the part 3 to be measured upwards on the bottom plate 4, and place the standard tungsten steel ball 2 in the countersunk head of the...

Embodiment 2

[0052] Embodiment 2. The difference from Embodiment 1 is that the bottom plate 4 is a flat plate made of ordinary iron, stainless steel or alloy, without magnetism.

Abstract

The invention discloses a quick detection method for countersunk head hole depth of flat head screw. According to the technical scheme adopted by the present invention, the method comprises the following steps of: using prior measurement gauges (height ruler, inner and outer diameter micrometer, standard tungsten steel ball) to measure; and obtaining a depth h of a countersunk head more accuratelythrough calculation. Compared with the prior art, the invention has advantages that the detection method is simple and can be completed by ordinary quality inspectors, the measurement efficiency is high, the detection device is simple, and the detection cost is low.

Description

technical field [0001] The invention relates to the technical field of countersink hole detection, in particular to a method for quickly detecting the depth of countersink holes of flat-head screws or flat-head rivets. Background technique [0002] Many stamping parts now have such salad holes, and the tolerance requirements for hole depth h and hole diameter d are relatively high, and frequent inspections are required during production. [0003] At present, the detection method of the depth h mainly uses a coordinate measuring machine to measure or a projector to project. Although these two measurement methods are accurate, the three-coordinate measuring instrument and projector equipment are expensive, the environment requirements are high, the measurement speed is slow, the efficiency is low, and special quality personnel are required to operate, so the measurement cost is very high. Contents of the invention [0004] In view of the above existing problems, the present...
