Embodiment Construction

[0019] An embodiment of a positioning pin assembly tooling of the present invention: as Figure 1-3 As shown, the inside of the frock body 9 is provided with a stepped hole with a large top and a small bottom. The upper large hole section is a guide hole for guiding the screw pressing mechanism. Cooperating internal thread segment 13, the outer circumference of the screw sleeve 3 is convexly provided with a stop edge 15 that is matched with the upper hole wall of the tooling body 9, and the center of the screw sleeve 3 is provided with an internal thread hole 16 that is threadedly matched with the screw rod 2, The screw rod 2 is a stepped rod with a small upper part and a larger lower part. The outer circumference of the small diameter section at the upper end of the screw rod 2 is provided with a threaded section. large hole fit. The upper end of the screw rod 2 is radially provided with a radial through hole 17 for the hand rod 1 of the rotating screw rod 2 to pass through,...

Abstract

The invention provides a locating pin assembly tool. The locating pin assembly tool comprises a tool body, a guide hole vertically extending from the upper end face towards the lower vertical face is formed in the tool body, a spiral jacking mechanism is assembled in the guide hole, the lower end of the spiral jacking mechanism is provided with an ejector pin used for jacking a locating pin, a guiding structure used for preventing the locating pin from deflecting and guiding the locating pin when the ejector pin jacks the locating pin is arranged at the lower end of the tool body, and a locating and supporting mechanism used for locating and supporting a workpiece is arranged at the lower end of the tool body. When the locating pin assembly tool is used, a locating hole in the workpiece is aligned to the locating pin, and the ejector pin can be driven to enable the locating pin to be pressed into the workpiece by simply rotating a screw. By the adoption of the locating pin assembly tool, the problem that assembly is difficult when the workpiece is suspended or the assembly space is narrow is solved, and the labor efficiency is improved.

Description

technical field [0001] The invention relates to a positioning pin assembly tool. Background technique [0002] Locating pins are often used for positioning, connection and fixing between parts. They have good shear resistance and their outer diameter is slightly larger than the assembly hole diameter. Therefore, when locating pins are assembled, they are mostly interference fits. They are generally driven in with a hammer. , but in mechanical processing and manufacturing, it is often encountered that the workpiece is in a suspended position or the assembly space of the workpiece is narrow. At this time, it is very inconvenient to smash it with a hammer, which greatly increases the difficulty of work. Contents of the invention [0003] The invention provides a positioning pin assembly tool, which is used to solve the problem of difficult assembly when the assembly space is narrow. [0004] In order to solve the above problems, the positioning pin assembly tool provided by ...
