Fixing mechanism with cooling device for machining bearing

Abstract

The invention discloses a fixing mechanism with a cooling device for machining a bearing. The fixing mechanism comprises a main shaft box, a fixing clamp and a water cooling device, wherein a main shaft is installed in the main shaft box, a rotating plate is installed on the front end of the main shaft, the fixing clamp is installed on the rotating plate, the water cooling device is installed on the upper end of the main shaft box, the fixing clamp comprises a fixed shaft, a guide base, an annular push plate, a clamping block and a limiting block, the water cooling device comprises a water tank, a fixed rod, a slide block, a transverse motor, a telescopic air cylinder and a spray head. The fixing mechanism is suitable for different bearings in different sizes, the clamp does not need to be replaced when the bearings in different sizes are machined, the fixing effect is good, the machining efficiency is greatly improved, the cooling water sprayed out by the spray head passes by a top plate and a spraying disc, the atomizing effect is good, the cooling water acting on the workpiece can be rapidly evaporated to bring away the heat on the workpiece, the cooling effect is good; moreover, the spray head can be flexibly adjusted under the driving of the slide block, and the practicability is relatively high.

Description

【Technical field】 [0001] The invention relates to the technical field of bearing processing equipment, in particular to the technical field of a fixing mechanism with a cooling device for bearing processing. 【Background technique】 [0002] Bearings are components that fix and reduce the friction coefficient of loads during mechanical transmission. It can also be said that when other parts move relative to each other on the shaft, it is used to reduce the friction coefficient in the process of power transmission and keep the center of the shaft fixed. Bearings are an important part of modern mechanical equipment. Its main function is to support the mechanical rotating body to reduce the friction coefficient of the mechanical load during the transmission process of the equipment. According to the different friction properties of moving elements, bearings can be divided into two types: rolling bearings and sliding bearings. Bearings usually require special fixtures to fix th...

Problems solved by technology

Bearings usually require special fixtures to fix the bearings during processing and grinding, but the existing fixtures have poor fixing effects and cannot adapt to bearings of different sizes. For bearings of different sizes, the fixtures need to be replaced, and the processing efficiency is low. In addition, the bearings are being processed. In order to prevent the workpiece from being damaged due to overheating during grinding, it is usually necessary to cool the workpiece with water to ensure the quality of the product. However, the cooling water in the existing water cooling device is directly sprayed from the water pipe, and the atomization effect of the cooling water is poor, and the cooling effect is not enough. Ideal, and the existing water-cooling device cannot move flexibly, and the position of the outlet pipe cannot be adjusted in time according to the change of the processing part of the bearing. The practicability of the device needs to be improved
