Screwing-embedding integrated rapid reset key-locking threaded insert mounting device

Abstract

The invention provides a screwing-embedding integrated rapid reset key-locking threaded insert mounting device. The device comprises a guide rod, a sleeve, a spring, a stop block, a gland and an end cover. Four guide keys are arranged at the front section of the guide rod and matched with the four guide grooves inside the sleeve, the spring and the stop block penetrate through the rear end of theguide rod in sequence to be installed in the sleeve, the gland is installed at the rear end of the sleeve for pressing the stop block, the end cover is arranged at the rear end of the guide rod, and the guide rod, the spring, the stop block, the gland, the sleeve and the end cover are coaxially connected. According to the device, the screwing and embedding integrated installation of key-locking threaded inserts can be realized, plug pins can be quickly and continuously embedded in the installation process by virtue of spring rebounding reset, and compared with a traditional installation mode,the device has the advantages of being simple and convenient to operate, good in installation quality and high in production efficiency, and can be widely applied to installation of the key-locking threaded inserts.

Description

technical field [0001] The invention belongs to the fields of mechanical structure and mechanical electronics. Background technique [0002] Threaded connection is the most widely used detachable connection. It has the advantages of simple structure, convenient assembly and disassembly, and low cost. However, for some light alloy (aluminum, magnesium, etc.) low-strength engineering materials, the thread generated on the material itself Strength and wear resistance often cannot meet the actual load-bearing needs. The plug screw sleeve is the threaded connection structural element that solves these shortcomings. It uses higher strength materials and is installed in a specific screw hole of the light alloy substrate to form a standard thread on the inner surface. When mated with fasteners, it can significantly improve the strength and wear resistance of threaded connections. [0003] The structure of the plug screw sleeve is relatively simple, mainly composed of internal and ...

Problems solved by technology

When this installation method is manually screwed into the screw sleeve, the bolt may be bent and tilted due to uneven force, and when the hammer directly hits the top of the bolt, the hammering force may be too large or uneven, which may also easily cause the bolt to bend, Tilting, or even breaking, at the same time, during the hammering process, the end of the hammer head may hammer the base material, resulting in bumps and dents easily appearing around the screw hole of the base material, which seriously affects the appearance quality of the base material

In addition, the installation of bolt screw sleeves is generally carried out in batches. This installation method is time-consuming and laborious, and the economic benefit is poor.
