Fixing device for testing mechanism for bearing processing

Abstract

The invention discloses a fixing device of a testing mechanism for bearing machining. The fixing device comprises a fixing shaft. A connector is fixedly arranged at one end of the fixing shaft. Brake rods are arranged in an inner cavity of the fixing shaft. Two push rods are fixedly arranged on the surface of each brake rod. The ends, far away from the brake rods, of the push rods penetrate the fixing shaft and are fixedly connected with extrusion plates at the outer portion of the fixing shaft. The extrusion plates are fixedly connected with speed reduction columns through installing plates installed at the bottoms of the extrusion plates. The ends, far away from the installing plates, of the speed reduction columns are inserted into speed reduction grooves formed in the surface of the fixing shaft to be fixedly connected with the inner walls of the speed reduction grooves. The fixing device of the testing mechanism for bearing machining is provided with the brake rods, bearings arranged on the fixing shaft in a sleeving manner are fixed, and therefore the bearings are fixed more conveniently; and in cooperation with the speed reduction columns, the adjustment of the extrusion plates is more accurate; clamping shafts are arranged, and therefore the fixing speed is higher; and a telescopic rod and fixing plates are arranged, and therefore the fixing device can be suitable for bearings of different sizes, and the influence on the bearing test from the outside is reduced.

Description

technical field [0001] The invention relates to the technical field of bearing processing, in particular to a fixing device for a testing mechanism for bearing processing. Background technique [0002] Bearing is an important part of contemporary mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient (friction coefficient) during its movement, and ensure its rotation accuracy. According to the different friction properties of moving elements, bearings can be divided into two categories: rolling bearings and sliding bearings. Among them, the rolling bearing has been standardized and serialized, but compared with the sliding bearing, its radial dimension, vibration and noise are larger, and the price is also higher. The rolling bearing is generally composed of four parts: the outer ring, the inner ring, the rolling body and the cage. Generally speaking, it is composed of six parts: outer ring, inner ring, rolling el...

AI Technical Summary

Problems solved by technology

According to the shape of rolling elements, rolling bearings are divided into two categories: ball bearings and roller bearings. Currently, the bearings on the market often need to test the performance and safety of the bearings during the processing process, and the bearings are often used in the process of testing. External equipment is used for fixing, so it is not suitable for fixing bearings of various sizes, and it will also affect the structure of the bearing test
