Description

Technical Field

[0001] This utility model relates to the field of testing tooling technology, and in particular to a scanning rod rapid detection tooling assembly. Background Technology

[0002] With the development of dental implant technology, digital scanning technology is being used more and more widely in the field. Digital scanning technology has multiple functions in dental implantation, including capturing implant position data, taking impressions, and replacing healing abutments. The scanning lever is a crucial component in digital scanning technology, used by dentists to obtain intraoral scan data from patients. As digital scanning technology advances, the demand for scanning levers is gradually increasing, leading to a greater variety of types and functional requirements. In production applications, not only functional requirements but also manufacturing feasibility must be considered.

[0003] Since the scanning probe is used inside the patient's mouth, controlling its size is particularly important. If the scanning probe is too large, it will compress the gums, causing discomfort to the patient; if the scanning probe is too small, it will be difficult to extract large areas of data during digital scanning and will be difficult to align in dental design software. In related technologies, the diameter of the scanning probe is generally designed to be 4-6mm.

[0004] In related technologies, projector measurement is used to measure the size of the scanning rod. However, if the scanning rod has many curved features, is irregular, or has many cross-sections, projector measurement is difficult to accurately measure the size of the scanning rod, or even fails to measure the size at all. This makes it impossible to control the size of the scanning rod and causes problems in the application. Utility Model Content

The pressing structure 1 and the disassembly structure 2 are respectively connected to the testing unit 3. The testing unit 3 includes: a retaining ring 31 and a detection plate 32. The retaining ring 31 is cylindrical and has a first through hole 311. One side end of the retaining ring 31 has multiple slots 312, and multiple detection plates 32 are engaged in the slots 312. During installation, the pressing structure 1 is used to press the detection plate 32 into the slots 312. During disassembly, the disassembly structure 2 is used to separate the detection plate 32 from the slots 312.

[0031] The testing plate 32 includes a connecting part 321, a plug-in part 322, and a locking part 323. The connecting part 321 is connected to the plug-in part 322, and the locking part 323 is connected to the plug-in part 322. The connecting part 321, plug-in part 322, and locking part 323 are on the same plane. When installed, the plug-in part 322 is inserted into the slot 312, and the connecting part 321 is placed in the first through hole 311. The shape of the locking part 323 is adapted to the scanning contour of the scanning rod to be tested. During testing, the locking part 323 is fitted to the outer contour of the scanning rod to be tested, and the results are obtained by observing the relationship between the locking part 323 and the outer contour of the scanning rod to be tested. Whether the fit is correct is used to determine whether the size of the scanning rod under test meets the preset requirements; multiple detection plates 32 are connected by a connecting part 321. Setting multiple detection plates 32 can meet the detection of different parts of the scanning rod under test. The shape of the fitting part 323 is set according to the outer contour shape of the scanning rod under test, which can meet the detection of scanning rods of different shapes. In this embodiment, the number of detection plates 32 is three, and the three detection plates 32 are connected by a connecting part 321.

The detection fixture is then installed and removed from the pressing top block 11 and the pressing base 12. During testing, the retaining ring is engaged with the retaining ring 312. Part 323 fits into the outer contour of the scanning rod to be tested. By observing whether the fitting part 323 fits into the outer contour of the scanning rod to be tested, it can be determined whether the size of the scanning rod to be tested meets the preset requirements. During disassembly, the thin pad 33 is placed in the positioning groove 221 of the disassembly base 22. The disassembly top block 21 is fitted into the retaining ring 31 by the upper side of the thin pad 33. The retaining ring 31 is placed in the second cavity of the disassembly top block 21. The second pressure column 213 extends into the first through hole 311 of the retaining ring and applies a vertical downward force to the disassembly top block 21, pressing the detection thin plate 32 out from the retaining groove 312 of the retaining ring 31. The detection thin plate 32 falls into the positioning groove, completing the disassembly.
