Description

Technical Field

[0001] The utility model relates to the field of thread detection, in particular to a detector which is convenient for detecting the concentricity of anode threads. Background Art

[0002] The existing patent (Announcement No.: CN219890355U) proposes a concentricity inspection tool for a stud threaded hole, comprising: a detection sleeve, the upper part of whose inner cavity is a small-diameter cavity, and the lower part of whose inner cavity is a large-diameter cavity; a guide rod, which is slidably arranged in the small-diameter cavity, and a spherical nut is arranged at the end of the upper end exposed to the detection sleeve, and a limit marking line is also arranged at a preset position below the spherical nut; a limit baffle, which is arranged at the end of the large-diameter cavity below the guide rod, and whose outer diameter is larger than the inner diameter of the small-diameter cavity; however, the structures of the "detection sleeve" and the "detection rod" in this device are relatively fixed. When the inner diameter of the threaded hole of the part to be detected is larger than the diameter of the detection rod, the detection rod can pass through even if the threaded hole and the part stud body are not concentric, which reduces the accuracy of the concentricity inspection result of the part anode thread, and there are disadvantages. Summary of the invention

[0003] The utility model aims at the above-mentioned deficiencies in the prior art and provides a method for detecting the concentricity of threads of anode parts having both internal and external threads. The detection process is convenient to operate, and is convenient for quickly detecting and judging the concentricity of the anode threads, avoiding the tediousness of using a projector and three-coordinate detection, greatly improving the detection efficiency, and being suitable for large-scale detection. The concentricity detection outer diameter and inner diameter of the parts can be changed accordingly according to the actual sizes of the internal and external threads of the parts, so that when the inner diameter of the threaded hole of the part to be detected is larger than the diameter of the detection rod, the detection rod can pass through even if the threaded hole and the part stud body are not concentric, thereby improving the accuracy of the anode thread concentricity detection result and ensuring the assembly and sealing performance of the threaded connector. A detector is provided that is convenient for detecting the concentricity of the anode threads.

The steel pipe 09 has a mounting convex sleeve 14. The mounting sleeve 13 is connected to the mounting convex sleeve 14 through threads. The concentric bottom ring 11 has a detection hole 12. When the anode thread concentricity of the part is detected, the part is placed into the detection cavity 19 through the detection hole 12. The detection ring 16 passes through the internal threaded hole of the part, and observes the depth of the part inserted into the detection cavity 19 through the observation holes 15 on both sides of the detection cavity 19. If the detection ring 16 passes through the internal threaded hole smoothly, the part stud is inserted into the detection cavity 19 until its upper surface fits with the surface of the cover plate 10, and the bottom surface of the stud is flush with the lower surface of the concentric bottom ring 11, then the concentricity test is passed. If the detection ring 16 cannot pass through the internal threaded hole smoothly, or the part stud cannot be inserted into the top of the steel pipe 09, or the bottom surface of the stud cannot be flush with the lower surface of the concentric bottom ring 11, then the concentricity test is failed. The detection process is convenient to operate, which is convenient for rapid detection and judgment of the concentricity of the anode thread, avoiding the tediousness of using a projector and three-coordinate detection, greatly improving the detection efficiency, and being suitable for large-scale detection. The steel pipe 09 has observation holes 15 on both sides, and the upper part of the steel pipe 09 has a cover plate 10, and the cover plate 10 has a positioning groove 05, and the positioning groove 05 is adapted to the positioning plate 04, and the positioning plate 04 is connected to the positioning groove 05, and the positioning plate 04 has a plurality of limit blocks 06, and the positioning groove 05 has a plurality of limit slots 07, and the limit blocks 06 and the limit slots 07 are connected.

The detection rod 03, the detection ring 16, the concentric bottom ring 11, and the steel pipe 09 are all fixed with threads, which are easy to disassemble and assemble, and are convenient for quick replacement of each component and convenient operation.

The detection result is accurate. The lower part of the positioning plate 04 is provided with a detection rod 03, and the detection rod 03 is provided with a mounting support rod 17.

The concentricity detection outer diameter and inner diameter can be changed accordingly according to the actual size of the internal and external threads of the parts, so as to avoid that when the inner diameter of the threaded hole of the part to be detected is larger than the diameter of the detection rod, even if the threaded hole and the part stud body are not concentric, the detection rod can pass through, thereby improving the accuracy of the anode thread concentricity detection result and ensuring the assembly and sealing performance of the threaded connector.
