Description

Thread detection machine

Technical Field

The utility model relates to the technical field of thread detection, in particular to a thread detector.

Background

The thread ring gauge is used for measuring the correctness of the size of the external thread, the through end is one piece, and the stop end is one piece. The end stop ring gauge is provided with a groove on the outer cylindrical surface. When the size is more than 100 mm, the thread ring gauge is in a double-handle thread ring gauge type. The specification is divided into three types of coarse thread, fine thread and pipe thread. The thread ring gauge with the thread pitch of 0.35 mm or less and the 2-level precision and the thread ring gauge with the thread pitch of 0.8 mm or less and the 3-level precision have no end stop; in the production process of portable electronic devices (such as mobile phones, personal digital assistants, and the like), a plurality of workpieces need to be assembled together through fasteners such as screws, and the like, each workpiece is provided with a thread structure matched with the fastener, the thread specification of the workpiece with the thread structure needs to be detected before assembly, and if the workpieces are assembled, if irregular screws are used, the connection of the workpieces is often unstable, so that the circuit is damaged. The thread measurement has two methods, namely single measurement and comprehensive measurement. Single term measurements are often used to measure parameters such as pitch, and profile half angle of a thread. Many parts need to be subjected to thread detection, and the most common detection method at present is to detect by using a thread ring gauge.
