Description

Technical Field

[0001] The utility model relates to the technical field of thread inspection, in particular to a checking tool capable of inspecting thread engagement at any position of a rod body. Background Art

[0002] With the increasing intensity of infrastructure construction in recent years, the demand for threaded rod bodies such as anchor rods is increasing. Currently, the checking tool for inspecting the thread engagement of screw rods is usually a ring gauge with internal threads. This kind of ring gauge cannot be opened and closed arbitrarily. During inspection, it can only be screwed in from one end of the rod body in circles for inspection, which is very time-consuming. Therefore, considering cost issues, enterprises generally only inspect the thread engagement of several hundred millimeters at the end of the rod body. However, the rod bodies are very long, such as 3m, 4m, 6m, etc., and some even reach 12.4m. In actual use, the rod body will also be cut off arbitrarily according to the usage needs. The cut-off section of the rod body may not necessarily have an end. If it is not detected, whether it can be screwed with the fitting is unknown. Once it does not match, it will affect the construction progress and cause losses.

[0003] The Chinese invention patent with the publication number CN105909656A discloses a split nut, which directly divides the nut into two rotatably connected half parts and sets a clamping mechanism at the free end of the rotational opening and closing to merge the two half parts, so as to improve the disassembly and assembly efficiency of the nut on the lead screw. However, its defect is that directly designing the hinge and clamping structures on the nut is too complex, which increases the processing and manufacturing difficulty. Moreover, when inspecting the same-diameter screw rods with different thread specifications, the entire nut needs to be completely replaced, which also increases the inspection cost. Content of the Utility Model

[0004] In order to overcome the deficiencies in the background art and solve the existing technical problems, the utility model discloses a checking tool capable of inspecting thread engagement at any position of a rod body, which has a simple structure, low cost, and is convenient for disassembly and replacement.

[0005] To achieve the above invention purpose, the utility model adopts the following technical solutions:

[0006] A checking tool capable of inspecting thread engagement at any position of a rod body includes a clamp assembly and a checking nut for inspecting the thread engagement of a screw rod. The checking nut is radially divided into a first half part and a second half part. The clamp assembly is configured to be able to externally sleeve and clamp the first half part and the second half part, so that the corresponding cut sections can be closely attached to form a detachable structure of the checking nut. The cut sections of the first half part and the second half part are respectively provided with a positioning groove and a positioning protrusion for fitting and inserting.

[0007] Further, the clamp assembly includes two half-ring clamp segments, and the two half-ring clamp segments are respectively clamped and positioned with the outer walls corresponding to the first half part and the second half part.

[0008] Further, threaded holes are provided on the outer walls of the first half-piece and the second half-piece, and through holes for the fitting positioning screws to pass through and be screwed for positioning are provided on the semi-ring hoop section corresponding to the corresponding threaded holes.

[0009] Further, one corresponding end of the two semi-ring hoop sections is hinged, and the other corresponding end is snap-connected.

[0010] Further, the number of positioning grooves on the first half-piece is set to two, and the two positioning grooves are respectively arranged at different ends of the two splitting cross-sections of the first half-piece.

[0011] Further, end-face marks are provided at the corresponding ends of the first half-piece and the second half-piece.

[0012] Further, cushion pads are provided at the positions on the outer walls of the first half-piece and the second half-piece corresponding to the positions where the corresponding semi-ring hoop sections are closely attached.

[0013] Further, the positioning protrusion is made of a magnetic material, and a magnet is provided at the bottom of the positioning groove.

[0021] Combined with the attached Figures 1-3 The fixture capable of inspecting the screwing at any position of the rod body includes a clamp assembly 3 and a checking nut for screwing and inspecting the screw. The checking nut is radially divided into a first half 1 and a second half 2, and it is preferably evenly divided into two halves. The clamp assembly 3 is configured to be able to externally sleeve and tighten the first half 1 and the second half 2 so that their corresponding cut surfaces can be closely attached to form a detachable structure of the checking nut. Generally, one corresponding end of one side of the two half-ring clamp segments 301 is hinged, and the corresponding end of the other side is snap-connected. Specific snap-connection structures of various clamps are relatively common and will not be elaborated here too much. More conveniently, the following is adopted Figure 1 This kind, which is tightened by turning the bolt and tightening the nut; as required, the clamp assembly 3 includes two half-ring clamp segments 301, and the two half-ring clamp segments 301 are respectively clamped and positioned on the corresponding outer walls of the first half 1 and the second half 2 to prevent relative sliding between the clamp assembly 3 and the checking nut during inspection.
