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

[0041] 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.

[0042] Such as Figure 1-4 As shown, a threaded hole detection device includes: an image detection mechanism 1 and a carrier table 11 disposed toward one side of the image detection mechanism 1, and an image device facing the carrier table 11 is provided on the image detection mechanism 1. And there are two imaging devices inclined toward the carrier table 11, which affect the movement between the detection mechanism and the carrier table 11, and the carrier table 11 can move in its plane. The imaging device is a CCD camera.

[0043] The CCD camera installed in the forward direction and the CCD camera installed in an inclined manner have a cl...

Abstract

The invention relates to a threaded hole detection device, which comprises an image detection mechanism and a carrier table top arranged at one side of the image detection mechanism, wherein the image detection mechanism is provided with at least one image device facing the carrier table top in a forward mode and at least one image device facing the carrier table top in an inclined mode; the image detection mechanism and the carrier table top can move in a relative approaching mode; the carrier table top can move in a plane where the carrier table top is located; the CCD cameras which are arranged in a forward mode and in an inclined mode detect each quality index of the inner thread individually; the CCD cameras with different angles are arranged on a fixing plate, and all quality index items of the same inner thread can be detected; as at least two inclined CCD cameras are arranged, detection and calculation on the inner threaded hole in at least two different angle directions can be realized, sampling is more complete, and the detection omission rate is greatly reduced; and the two inclined CCD cameras are matched for detecting the position and the angle of a screw tooth at the free end of two end parts in the inner thread.

Description

technical field [0001] The invention relates to a thread quality detection device, in particular to a threaded hole detection device. 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. However, the detectio...
