Rigidity testing device for non-oil bearing

Abstract

The invention relates to a rigidity testing device for a non-oil bearing. The device comprises a device body, a working table, a press head device, a micrometer eyepiece, a lens, a touch control screen and a testing force loading mechanism, wherein the working table, the press head device, the micrometer eyepiece, the lens and the touch control screen are installed on the exterior of the device body, and the testing force loading mechanism is installed in the device body; the working table is located below the device body and comprises a lifting table, an air cylinder, a fixing base and a moldtool special for the bearing, and the air cylinder is located in the device body; the lifting table is connected to the upper portion of the air cylinder, the mold tool special for the bearing is arranged at the upper end of the lifting table and comprises a circular shaft and a fixing rack, and the diameter of the circular shaft adapts to the inner diameter of the testing bearing; threads are arranged at the two ends, the fixing rack is composed of two steel plates with mounting holes and fixed to the top face of the lifting table, and the bearing which needs to be tested is sleeved with thecircular shaft; the circular shaft is integrally connected with the fixing rack through a thread, and the fixing base is located at the lower end of the lifting table. According to an automatic lifting table technology and a technology of the mold tool special for the bearing, the device is easier and more convenient to operate, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the field of bearing testing, in particular to the field of a hardness testing device for oil-free bearings. Background technique [0002] The hardness tester is mainly used for the hardness determination of forged steel, cast iron, non-ferrous metals and soft steel, because it is the test method with the largest indentation in all hardness tests, which can reflect the comprehensive performance of the material and is not affected by the inner part of the metal. Influenced by the metallographic structure, the test hardness is stable, the precision is high, and the requirements for the surface of the part are wider than other hardness test methods, so it is widely used in metallurgy, forging and non-ferrous metals and other industrial fields, laboratories, colleges and scientific research units. .

AI Technical Summary

Problems solved by technology

In the prior art, the lifting table is generally lifted by a screw rod, which requires the tester to manually control the handwheel to lift, which reduces the work efficiency. In actual testing, the cylindrical bearing often causes inconvenience, and the bearing needs to be processed before it can be used. For testing, only one sample can be tested at a time, there is no contrast, and the work efficiency is also very low

Therefore, the existing technology can no longer meet the demand, and a new type of test device dedicated to bearings is needed.
