Description

Grinding device for shaft-connected bearing

Technical Field

The utility model relates to a bearing grinding processing field especially relates to a grinder for axle is bearing even.

Background

In modern machining, in the field of precision part machining, grinding is widely used as a high-precision finishing surface machining mode. Compared with grinding, when the same roughness effect is required, the grinding efficiency is higher, the surface roughness of the processed part can be greatly improved, particularly, the mechanical vibration is low in the grinding process, and the surface of the processed part can obtain low waviness.

In the grinding process, generally, oilstones with different granularities and hardness are used as grinding materials, and for rotary workpieces, the oilstones rotate in the processing process of the workpieces, and reciprocate or swing on the surfaces of the workpieces to be processed of the workpieces under certain pressure. For example, if the surface to be machined of the rotary workpiece is in a straight line shape, the oilstone moves in a reciprocating straight line on the surface to be machined, and if the surface to be machined of the rotary workpiece is in an arc shape, the oilstone moves around the center of the arc in a reciprocating swing mode on the surface to be machined, and in any mode, the core is that the oilstone moves in a reciprocating mode on the surface to be machined of the rotary body under certain pressure to form micro cutting.

For a rolling bearing, the waviness of the rolling surface of a bearing part has great influence on the dynamic performances of the rolling bearing, such as bearing vibration, noise and the like, when the rolling surface of the bearing part has very low surface roughness and waviness, the noise and vibration of the rolling bearing can be greatly reduced, meanwhile, the friction is reduced, the operation efficiency is improved, the energy is saved, and the consumption is reduced.

In order to match the use requirements of the automobile industry, the bearing industry provides a new bearing design scheme, a bearing, a shaft and a lubricating part are integrated into a whole, a bearing unit is a design scheme of two rows or three rows, namely, different types of bearings are integrated together, mainly a roller bearing, an angular contact ball bearing and a main shaft are integrated into a whole, the structure is compact and small, a bearing inner ring and the main shaft are integrated into a whole, namely, a roller path is directly processed on the outer diameter surface of the main shaft, sealing structures are designed on two sides of the bearing, lubricating grease capable of meeting the lifelong use requirements is filled in the bearing, unit integration is formed, the bearing can normally work under different working conditions, and the structure is called as a shaft connection bearing. For the shaft-coupled bearing, the moving surfaces of the ring and the main shaft are not in a single structural form, but in a plurality of combined structural forms, such as a combination of a straight line and an arc, the arc is generally a circular arc, but there is also a special form, such as an arc moving surface in the shape of a pointed arch, the shape of the pointed arch is composed of two circular arcs in the same shape, and each circular arc has an independent circle center.

At present, a multi-station processing mode is generally adopted for a grinding method of a shaft connecting bearing ring and a main shaft, namely different surfaces to be processed of workpieces are processed at different stations. The workpiece is grabbed by the mechanical arm or manually and placed on different stations for grinding, the mechanical arm or manually grabbed after grinding is placed on another station for grinding other surfaces, and the like is carried out until all the surfaces to be machined are ground, and the machined workpiece is taken out.

Taking a main shaft on a processing shaft bearing as an example, referring to fig. 9, for a linear portion 301 of a main shaft 300 to be processed to process a surface, the main shaft 300 to be processed is supported and driven by a roller to rotate, and oilstones reciprocate linearly on the surface to be processed at a certain frequency under a certain pressure to generate a grinding effect; in the curved portion 302 (i.e., the ogive-shaped channel and the arc-shaped channel) of the spindle 300 to be machined, the oilstone swings at a fixed arc center at a certain frequency on the surface to be machined under a certain pressure. Because different stations need to be supported by rollers to drive the main shaft to be processed to rotate, the equipment volume is large due to excessive stations, the processed main shaft is carried back and forth by a mechanical arm or a worker, the efficiency is low, and the processed surface is easy to collide and scratch; in addition, when a channel in a sharp arch shape and a channel in an arc shape are machined in the prior art, a main shaft to be machined is easy to move in a string mode, the positioning is not accurate enough, a state that oilstone is continuously repaired and damaged is easy to generate, and machining precision and efficiency are difficult to guarantee.
