Device for measuring axial clearance of bearing with shaft based on automobile water pump

Abstract

The invention provides a device for measuring the axial clearance of a bearing with a shaft based on an automobile water pump, and relates to the technical field of measuring devices.The device comprises a measuring clamp assembly, a clamping disc is inserted into the top of a measuring base, and the measuring clamp assembly can clamp and fix bearings with different specifications and lengths so as to complete the subsequent measurement of the axial clearance; meanwhile, the driving control assembly of the device can accurately measure the axial clearance of the shaft connecting bearings with different specifications and lengths through the measuring clamp assembly, so that a fixing tool and a measuring tool do not need to be replaced, the measuring efficiency is greatly improved, and the problem that when an existing measuring device is used, the measuring precision is high is solved. The problems that in the prior art, a tool can only fix the shaft connecting bearing to measure the axial clearance, adaptability is poor, corresponding fixing and measuring tools need to be replaced when shaft connecting bearings of different specifications and lengths need to be measured, and the steps are tedious are solved.

Description

technical field [0001] The invention relates to the technical field of measuring devices, in particular to a measuring device for the axial clearance of a shaft-connected bearing based on an automobile water pump. Background technique [0002] The shaft-connected bearing of the automobile water pump is a bearing used in the water pump of the automobile. At the same time, the water pump is a key component of the engine. When the shaft-connected bearing of the water pump is broken, it will cause water leakage or seizure, which will directly affect the cooling of the engine. Therefore, the water pump bearing is in production During processing, it is necessary to measure various parameters of the bearing to ensure the processing quality of the shaft-connected bearing. Among them, the axial clearance of the shaft-connected bearing is an important measurement data. [0003] However, when the current measuring device is in use, the tooling can only fix the shaft-connected bearing t...

AI Technical Summary

Problems solved by technology

[0003] However, when the current measuring device is in use, the tooling can only fix the shaft-connected bearing to measure the axial clearance, which has poor adaptability. Due to the various specifications and lengths of the shaft-connected bearing, when it is necessary to measure shafts with different specifications and lengths When measuring even bearings, it is necessary to replace the corresponding fixing and measuring tooling. The steps are cumbersome, very troublesome, the measurement efficiency is low, and the practicability is not high.
