Description

Technical Field

[0001] This utility model relates to the field of positioning pin technology, and in particular to a self-tapping positioning pin. Background Technology

[0002] Locating pins, using workpiece holes as positioning references, are parts that restrict the degrees of freedom of an object, controlling its linear motion in the X, Y, and Z axes and its rotational motion around the X, Y, and Z axes (six degrees of freedom). In molds composed of two or more parts, they are designed to accurately position adjacent parts. When a machine body is composed of multiple connected parts, and each part needs to maintain precise position during machining and assembly, locating pins should be used. For example, in a split housing consisting of a cover and a base, the machining of bearing holes requires high precision; therefore, two locating pins spaced far apart should be placed on the split surface to ensure machining and assembly accuracy. In the electronics and electrical appliance industries, the limiting connections of multi-layer circuit boards, and the positioning connections of multi-layer sheet metal in the sheet metal industry, precision positioning connections are required. A self-tapping locating pin is needed to accurately position and improve assembly efficiency, solving the aforementioned technical problems. Utility Model Content

[0022] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention, but are not intended to limit the present invention.

[0023] It should be noted that all directional indicators (such as up, down, left, right, front, back, upper end, lower end, top, bottom, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0024] In this utility model, unless otherwise explicitly specified and limited, the term "connection" should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral part; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0025] Furthermore, in this utility model, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated.
