Problems solved by technology

However, the detection of internal thread is not easy to realize. First, the internal thread is located in the hole, which is not easy to observe, especially the deep thread, which is also particularly difficult to detect.

Embodiment Construction

[0035] The present invention will now be further described in detail in conjunction with the accompanying drawings and embodiments. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present invention in a schematic manner, so it only shows the composition related to the present invention.

[0036] Such as figure 1 and figure 2 As shown, a threaded hole three CCD camera detection mechanism, one end is provided with a target area 11, the detection mechanism includes: at least two imaging devices arranged at a certain angle to each other, at least one imaging device is facing the target area 11, at least one The imaging device tilts toward the target area 11, and the extension lines of the imaging device lenses intersect at the same intersection point 18, which is located in the target area 11, and the imaging device is a CCD camera.

[0037] The CCD camera installed in the forward direction and the CCD camera installed in an inc...

Abstract

The invention relates to a threaded hole three-CCD camera detection mechanism. One end of the detection mechanism is provided with a target zone, and the detection mechanism comprises at least two image devices arranged at a certain angle. The detection mechanism is characterized in that at least one image device is arranged towards the target zone in a positive direction, at least one image device is arranged towards the target zone in an inclined manner, extension lines of lenses of the image devices intersect at the same intersection, and the intersection is positioned in the target zone. According to the detection mechanism, a CCD camera arranged in the positive direction and a CCD camera arranged in an inclined manner detect each quality index of an internal thread with clear division of labor, and the CCD cameras with two different angles are arranged on the same fixing plate so that all quality index items of the same internal thread can be integrally and simultaneously detected.

Description

technical field [0001] The invention relates to a thread quality detection device, in particular to a thread hole three-CCD camera detection mechanism. Background technique [0002] For internal threads provided on important parts, screws or screws need to be screwed in during installation. The problem that often occurs during the screwing process is that the quality of the internal thread causes the entire internal thread to slip or other damage occurs. Often due to damage to one internal thread, the entire important component will be scrapped and the loss will be large. In order to avoid the above-mentioned technical problems, it is necessary to perform quality inspection on the internal thread and the external thread on the screw in advance. After removing defective products, screw them in again. [0003] Because the screw or the external thread on the screw is located on the outside, it is easy to pre-detect the thread on its surface and reject defective products. How...
