Description

Technical Field

[0001] This utility model relates to a tool, more specifically, a positioning device for quickly pressing positioning pins onto engine housing parts. Background Technology

[0002] When assembling engine housing components, locating pins are typically used to connect the upper and lower housings. These pins ensure accurate positioning of the upper and lower housings during assembly, preventing misalignment and guaranteeing assembly precision. Furthermore, using locating pins simplifies the assembly process, reduces adjustment time, and increases the connection strength between the upper and lower housings.

[0003] Problems and shortcomings of existing technology: Currently, the pressing and installation of locating pins for engine housing parts is done manually. Workers first pre-insert the locating pin into the locating hole on the assembly surface, then use a hammer to tap the locating pin to the required pressing depth. Due to variations in manual force and hammering direction, the pressing accuracy is poor, and the perpendicularity between the locating pin and the locating pin hole cannot be guaranteed. This method often results in tilted pressing of the locating pin. Therefore, it is necessary to develop a positioning device for the rapid pressing and installation of locating pins for engine housing parts. Utility Model Content

Both shoulders of the guide block have through positioning holes. Each positioning hole contains a detachable positioning block. The positioning block includes a cylindrical first rod diameter and a cylindrical second rod diameter. A stepped rod diameter is provided between the connection between the first rod diameter and the second rod diameter.
