The detection tube 1 can quickly confirm whether the aperture diameter of the open hole meets the requirements, so that the complicated steps of firstly measuring and then comparing to determine whether the hole to be detected meets the requirements are omitted, the detection tube 1 is arranged to enable the detection result to be more visual and clear, in addition, the point position detection assembly can detect the machining condition of a specific point position, and the repairing work after the open hole of the deck is bigger is facilitated.
In some embodiments of the present application, as shown in fig. 2, the point position detecting assembly includes a spring 2, a contact probe 3 and a strain gauge 4, the spring 2 and a part of the contact probe 3 are disposed in a large hole of the step accommodating hole 11, the strain gauge 4 is disposed near a small hole of the step accommodating hole 11, one end of the spring 2 is fixedly connected with the contact probe 3, and the strain gauge 4 is disposed in contact with the spring 2. The contact probe 3 is contacted with the hole wall of the hole to be detected, the hole wall can move inwards for the reverse-acting pressing contact probe 3, so that the spring 2 can be compressed under the moving action of the contact probe 3, the spring 2 is in contact with the strain gauge 4, pressure is transmitted to the strain gauge 4, the strain gauges 4 at different points are subjected to different compressive stresses, and whether the hole to be detected needs to be repaired or not and the specific repair position can be known by comparing the compressive stresses at the points.
The strain gauge 4 is, for example, a resistive strain gauge. The working principle of the resistance strain gauge is based on the strain effect, namely, when a conductor or a semiconductor material is mechanically deformed under the action of external force, the resistance value of the resistance strain gauge is correspondingly changed.
In order to facilitate the insertion of the test tube 1 into the hole to be tested, with continued reference to fig. 1 and 3, the deck opening precision testing device further comprises a handle 5, the handle 5 being fixedly arranged at the end of the test tube 1. The handle 5 is provided to facilitate insertion of the test tube 1 into the hole to be tested and extraction of the test tube 1 from the hole to be tested.
For example, the handle 5 is welded to the detection tube 1. Specifically, the handle 5 is welded to the end surface and the inner side surface of the detection tube 1, and thus the welding strength between the handle 5 and the detection tube 1 can be increased.
For example, the handle 5 is a round steel with a diameter of 10 mm. A specific structure of the handle 5 is provided here as long as insertion and extraction of the detection tube 1 can be achieved within a protective range.

The controller receives the data transmitted by the strain gauge 4 and calculates to obtain the compressive stress received by the strain gauge 4 at each point, and the display 6 receives the compressive stress calculated by the controller. In this embodiment, the controller may be a centralized or distributed controller, for example, the controller may be a single-chip microcomputer, or may be a distributed multi-chip microcomputer, where a control program may be run in the single-chip microcomputer, so as to control each component to implement its function.

the outer diameter of the detection pipe 1 is determined according to the holes to be detected of the deck, so that detection personnel can conveniently select detection devices with different sizes for the deck hole opening precision. Before selection, the diameter and the shape of the hole to be detected need to be determined, so that the detection tube 1 with the corresponding size can be selected quickly, and the detection efficiency is improved.
For example, the detecting tube 1 is a steel sleeve with the length of 50mm and the outer diameter corresponding to the specification of the hole to be detected, one end of the steel sleeve is selected to be in spot welding lap joint with a round steel sleeve with the outer diameter of 10mm and the length of the steel sleeve being +30mm, the round steel sleeve is symmetrically installed, two ends of the round steel sleeve respectively exceed the outer diameter of the detecting tube 1 by 15mm (the surface of a deck for perforating edges and prevent falling during perforating detection), a manufactured and formed object is subjected to surface galvanizing treatment like the steel sleeve, and the thickness of a galvanized layer is consistent with that of an actual steel sleeve galvanized layer.
S102, inserting the detection tube 1 into a hole to be detected of the deck;
the detection tube 1 is inserted into the hole to be detected of the deck, so that a detector can more intuitively see the size of the gap between the detection tube 1 and the hole to be detected.
S103, if the detection tube 1 cannot be inserted into the hole to be detected, continuing to process the hole to be detected until the detection tube 1 can be inserted into the hole to be detected; if the detection tube 1 can be inserted into the hole to be detected, whether the gap between the hole wall and the outer wall of the detection tube 1 is within a preset range is determined.
The gap size can be obtained by a clearance gauge, and the gap between the detection tube 1 and the hole to be detected is 1.5mm-2mm.
S104, if the gap between the outer wall of the detection tube 1 and the hole wall is in a preset range, qualified tapping; if the gap between the outer wall of the detection tube 1 and the hole wall is no longer within the preset range, the hole is unqualified.
And if the open hole is unqualified, the compressive stress of each point position is obtained through the point position detection assembly so as to determine the position of the point which is unqualified in processing.
The compressive stress at each point location is compared with a preset compressive stress stored in the controller, and for a profiled hole, the pressure at each point location should have a corresponding preset compressive stress range. Whether the holes are regular holes or special-shaped holes, the preset compression stress ranges corresponding to the points are in one-to-one correspondence, and the preset compression stress ranges are in a mapping relation, so that the comparison and calculation of the controller are facilitated, and the detection precision is improved. The detection personnel only need insert detection tube 1 in waiting to detect the downthehole detection of deck trompil precision.
According to the method, the detection device for the deck perforating precision can be rapidly selected according to the shape and the size of the hole to be detected, whether the hole to be detected is perforated or not can be rapidly determined by extending the detection pipe 1 into the hole to be detected, and detection personnel only need to insert the detection pipe 1 into the hole to be detected so as to achieve detection of the deck perforating precision.
According to the method provided by the application, a physical reduction method is adopted, more accurate data can be obtained through accurate positioning of the physical, and errors caused by human factors in the traditional measurement method are avoided. The detection time is greatly shortened, and the complicated process of measuring and analyzing one by using traditional tools such as a ruler is avoided. The detection result can be directly seen through detection, so that the subsequent data processing and management are convenient.
Furthermore, the foregoing description of the preferred embodiments and the principles of the invention is provided herein.
