Split type bearing bush thickness detection device

Abstract

The invention discloses a split type bearing bush thickness detection device, which comprises a measurement structure. The measurement structure is provided with a fixed measuring head and a movable measuring head which are coaxially and oppositely arranged, an object placing surface is arranged below the fixed measuring head and the movable measuring head, and the object placing surface is parallel to the axes of the two measuring heads and is used for placing a bearing bush. According to the bearing bush thickness detection device, due to the fact that the fixed measuring head, the movable measuring head and the object placing face are arranged, when the thickness of a bearing bush is detected, the thickness of the bearing bush can be detected only by placing the bearing bush between the fixed measuring head and the movable measuring head; as the object placing surface is parallel to the axes of the two measuring heads and is used for placing the bearing bush, the bearing bush is simultaneously placed on the object placing surface and is positioned between the fixed measuring head and the movable measuring head, and the bearing bush is pulled, so that the bearing bush slides on the object placing surface and also slides between the fixed measuring head and the movable measuring head; all dimensions of a certain height on the bearing bush can be measured, and the measurement mode is simple and fast.

Description

technical field [0001] The invention relates to a bearing pad thickness detection device, in particular to a split type bearing pad thickness detection device. Background technique [0002] The bearing pad is the part where the sliding bearing and the journal are in contact. The shape is a tile-like semi-cylindrical surface, which is very smooth. It is generally made of wear-resistant materials such as bronze and anti-friction alloy. It mainly supports the load and transmits motion between the shaft and the seat. The bearing bush is a friction pair, and some have an oil groove in the middle for oil lubrication. The crankshaft of the automobile engine is installed in the main bearing hole on the cylinder block, and the main bearing bush is installed in each main bearing hole. The structure of the steel back plus anti-friction alloy, the engine bearing is the part where the sliding bearing and the journal are in contact. In order to ensure the formation of an oil film, lubri...
