Location locking mechanism

Abstract

The invention relates to a location locking mechanism. An installation hole and a guide hole which is positioned at the lower part of the installation hole are arranged in an outer sleeve; the upper part of the outer sleeve is provided with an I-shaped groove which radially penetrates through the installation hole, the lower part is provided with a step shaft, and the bottom of the step shaft of the outer sleeve is also provided with more than three elastic claws with equal diameter; the peripheries of the more than three elastic claws transit from top to bottom from a front conical column toan inverted conical column; a connecting element is arranged in the installation hole of the outer sleeve; an adjusting cap covers the top of the outer sleeve; a transverse pin which is installed on the connecting element penetrates through the I-shaped groove on the outer sleeve and is installed in a pin hole of the adjusting cap; the upper part of a guide ejecting rod is screwed to the connecting element and locked by a locking nut; the guide ejecting rod is arranged in the guide hole in the outer sleeve, and springs which are sleeved on the guide ejecting rod are respectively abutted against the connecting element and the outer sleeve; and the diameter of the guide ejecting rod is larger than that of inner hole outlets of the more than three elastic claws. The invention has the characteristics of accurate location, convenient operation and great improvement of assembly efficiency.

Description

technical field [0001] The invention relates to a positioning and locking mechanism, which belongs to the technical field of vehicle lamp manufacturing. Background technique [0002] Usually in the assembly process of lamps and lanterns, it is first necessary to position and lock the lamp housing on the limiting plate of the tooling before proceeding to the subsequent assembly process. remove. Usually, the positioning and locking of the lamp housing is to use bolts to locate and lock, and use the mounting holes on the mounting feet of the lamp housing. During operation, place the mounting feet on the lamp housing on the limiting plate with screw holes, The bolt passes through the mounting hole on the mounting foot and is screwed into the screw hole on the limiting plate, and the bolt is pressed against the upper end surface of the mounting foot of the lamp housing to position and lock the lamp housing on the limiting plate. This positioning and locking structure has the ad...

Problems solved by technology

Furthermore, because the lamp housing is positioned and locked on the limiting plate by screwing the bolts on the limiting plate, after multiple positioning and locking, on the one hand, the thread on the limiting plate is also easy to be worn, which is easy to use. The bolt installation is deflected, which affects the positioning accuracy. On the other hand, the limit plate will also damage the threaded hole due to the frequent loading and unloading of the bolt, resulting in damage to the limit plate.
