Fixing device for machining bearing

Abstract

The invention discloses a fixing device for machining a bearing. The fixing device comprises a mounting base plate and a bearing plate; the two ends of the mounting base plate are each provided with abolt; the bearing plate is arranged at the middle position of the top of the mounting base plate and at one side of each bolt; the middle position of the top of the bearing plate is provided with a fixing seat; an inner arc is arranged at the inner side of the fixing seat; an oil dividing pipe is arranged inside the fixing seat and is connected with oil inlets; the surface of the inner arc is provided with first hydraulic telescopic rods; and the top end of each first hydraulic telescopic rod is provided with a driving roller. In the fixing device disclosed by the invention, the bearing is bidirectionally fixed by the fixing device by virtue of the fixing seat and an inner fixing disc so as to guarantee the stability of the bearing in a machining process; meanwhile the clamping force of the fixing device can be enhanced by utilizing the first hydraulic telescopic rods and second hydraulic telescopic rods; a traditional manual fixation way is not required; and the operability of the fixing device is improved.

Description

technical field [0001] The invention relates to the technical field of bearing processing, in particular to a fixing device for bearing processing. Background technique [0002] Bearings are an important part of contemporary mechanical equipment. Its main function is to support the mechanical rotating body, reduce the 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. [0003] During the production and processing of the bearing, it is necessary to fix the bearing itself first to avoid the deviation of the bearing and affect the accuracy of the bearing itself. The bearing fixing devices currently on the market a...

Problems solved by technology

Among them, the rolling bearing has been standardized and serialized, but compared with the sliding bearing, its radial size, vibration and noise are larger, and the price is also higher.

[0003] During the production and processing of the bearing, it is necessary to fix the bearing itself first to avoid the deviation of the bearing and affect the accuracy of the bearing itself. The bearing fixing devices currently on the market are inconvenient to operate, have poor flexibility, and have small support strength. It is prone to slipping and has poor stability. A new type of fixing device for bearing processing is urgently needed
