Detection device for detecting whether long and thin hole in long and thin part is unblocked

Abstract

The invention discloses a detection device for detecting whether a long and thin hole in a long and thin part is unblocked. The detection device comprises a non-transparent box body. The non-transparent box body comprises a movable cover plate. At least one side of the cover plate is provided with a notch. A transparent support plate is arranged on the middle part of the non-transparent box body. In detection, the long and thin part to be detected is arranged on the support plate and is capable of penetrating through the notch. The detection device also comprises a light source arranged in the box body below the support plate. By adopting the detection device for detecting whether the long and thin hole in the long and thin part is unblocked, the detection efficiency is improved.

Description

technical field [0001] The invention relates to the field of detection tools, in particular to a detection device for detecting whether the slender holes on slender parts are unblocked. Background technique [0002] In the field of mechanical processing, especially in the field of engine parts processing, the elongated holes on slender parts are generally used as oil holes for lubrication or liquid holes for cooling. It is characterized by difficult processing and inconvenient detection. However, whether such holes are unblocked or not will directly affect the normal operation and service life of mechanical equipment. [0003] At present, there are mainly two ways to detect whether the slender hole on the slender parts is unblocked: one way is to use a detection rod slightly smaller than the aperture to poke into the slender hole to detect whether the hole is unblocked; the other The method is to lift up the slender parts by hand, aim one end of the slender hole at a brigh...

Problems solved by technology

[0004] However, in the prior art, the first method is to poke the stick into the hole on the slender parts to detect whether the hole is unblocked. This method is relatively inefficient because it needs to detect each hole one by one.

In addition, if the apertures of the parts to be inspected are different, it is necessary to manufacture inspection rods of different diameters, which takes a long time to prepare, and the detection room is easy to take the wrong inspection rod, and the detection efficiency is not high

The second method is the traditional single-part hole-to-light detection method. This method requires the part to be lifted up by hand, usually one piece at a time, so the detection efficiency is relatively low.

In addition, if the size of the part is relatively large and the weight is heavy, the part cannot be manually lifted up and aligned with the light source, and the detection will not be possible.

In addition, the light source of this detection method is generally a natural light source, and the working time is limited
