Description

Technical Field

[0001] The utility model relates to the field of mechanical structures, in particular to an axle box grounding copper sheet installation limiter. Background Art

[0002] The axle box grounding copper sheet (hereinafter referred to as "copper sheet") is a connecting component that connects the vehicle body to allow the grounding current to flow to the wheel axle. In the prior art, the copper sheet is installed at the upper left corner of the axle box front cover, and the installation order is that the screw passes through the axle box ear, the front cover ear, the axle box grounding copper sheet, and finally the nut is used to tighten it. In the process of tightening the nut, the screw and the copper sheet will produce random rotation. In order to ensure the smooth progress of the tightening operation, two people are often required to divide the work, that is, one person clamps the screw to prevent it from rotating and tightens the nut, and the other person uses a fixed wrench to hold the copper sheet horizontally and pull it in the opposite direction, thereby preventing the rotation of the axle box grounding copper sheet during tightening. This two-person method of tightening the copper sheet has the following problems:

[0003] (1) High labor costs and low manual installation efficiency;

[0004] (2) The manual locking of the axle box grounding copper sheet cannot ensure that the assembly angle of each copper sheet is consistent, resulting in low installation and positioning accuracy of the copper sheet;

[0005] (3) When the installation angle of the axle box grounding copper sheet is not correct or the manual locking fails, the nut needs to be loosened to adjust the angle of the grounding copper sheet, which results in a high rework rate. At the same time, the anti-loosening effect of the screw and nut will be reduced, or at least one of the screw and nut will be directly scrapped, which not only reduces the installation strength of the copper sheet, but also increases the replacement cost of the screw and nut;

[0006] (IV) When manually locking the screw or pulling back the copper sheet, slipping and other phenomena may easily occur, which is dangerous and may easily cause personal injury. Utility Model Content
