Description

Nut Inspection Equipment

The present invention relates to a nut inspecting apparatus, and more particularly, to a nut inspecting apparatus, more particularly, to a nut inspecting apparatus, more particularly, to a nut inspecting apparatus using a principle of a force in a tangential direction of both ends located on the same center line of a rotating rotating body, The present invention relates to a nut inspecting apparatus which can inspect nuts of various names according to a gauge exchange.

Generally, various types of nuts are used in the fastening process of machines and devices. Since the fastening force and airtightness of the machine and the apparatus depend on the precision of the nut, the accuracy of the diameter, depth, and thread dimensions of the thread formed on the nut is very important for the performance of the machine and the apparatus.

In the past, the number of turns of the thread was calculated by measuring only the simple depth of the threaded nut in checking whether the thread formed in the nut is defective or not. In the conventional method as described above, the number of turns of the thread can not be accurately quantified, and it is only possible to check whether the thread is defective by the depth measurement, so that the accuracy of the measurement result is low and an error of one thread or more can be obtained.

Also, in order to solve the above-mentioned problem, there is a manual inspecting machine in which an operator inspects a screw by manually inserting a thread into a nut formed by manual operation. The conventional method as described above requires a long time for inspection, requires a labor cost and other inspection costs, and it is difficult to accurately detect a defective part even if a skilled inspector tests it.

In addition to inspecting screw holes by hand, a laser inspection method is known. According to this method, although the diameter and depth of the screw holes can be relatively accurately and easily inspected, It is impossible to check defects or the like, so that there is a problem in increasing the accuracy.

In the related art, it is described in Korean Patent No. 10-1336651. However, since there is a manual inspection to confirm the screw while tightening it by hand, it is difficult to grasp the exact defect and the working efficiency is lowered. It does not.

First, a nut inspection apparatus according to the present invention is provided with a base 100.

The base 100 is formed in a plate shape as shown in FIG.

In addition, a plurality of cylindrical support rods 200 provided vertically coupled to the upper end of the base 100 are provided.

An upper fixing table 300, which is formed in a rectangular shape on the support table 200, is provided. And serves to couple and fix the supporter 200.

In addition, a control block 400 is formed on the top of the upper fixing table 300 in a rectangular shape in combination with the top fixing table 300.
