Description

Technical Field

[0001] The utility model belongs to the technical field of bearing processing, in particular to a bearing internal circle processing grinder. Background Art

[0002] Bearings are an important component in contemporary mechanical equipment. Its main function is to support mechanical rotating bodies, reduce the friction coefficient during their movement, and ensure their rotation accuracy. Bearings can be divided into two categories: rolling bearings and sliding bearings according to the different friction properties of the moving elements. Bearings are composed of four basic parts: inner ring, outer ring, rolling element, and cage. The inner ring is usually tightly fitted with the shaft and rotates with the shaft; the outer ring is generally matched with the bearing seat or the housing of the machine to play a supporting role; the rolling element is evenly distributed between the inner ring and the outer ring with the help of the cage. The shape of the rolling element is a ball, a short cylinder, and a cone; the cage can make the rolling element evenly distributed, prevent the rolling element from falling off, and guide the rolling element to rotate and play a lubricating role. The inner ring of the bearing is processed by a grinding machine to ensure the roundness and surface quality of the inner ring of the bearing.

[0003] The utility model with application number CN202322188410.0 discloses a bearing internal grinding machine, including a workbench, a clamping mechanism arranged on the workbench for clamping a bearing ring, and a transport mechanism and a collection device. The clamping mechanism is a three-jaw chuck, and the transport mechanism includes a guide plate and a driving member 1. The axial direction of the receiving ring after being clamped by the clamping mechanism is a first direction. The driving member 1 drives one end of the guide plate to rotate along the first direction. When the guide plate rotates to the receiving state, the guide plate is in an inclined state, and the guide plate receives the clamped bearing ring and guides it into the collection device; when the guide plate rotates to the protection state, the receiving surface of the guide plate is away from the three-jaw chuck. When the guide plate is driven to rotate to the receiving state, under the tilting action of the guide plate, the bearing ring will move toward one side of the collection device and be collected by the collection device; when the guide plate is driven to rotate to the protection state, the probability of waste chips adhering to the surface of the bearing ring when it moves on the guide plate can be reduced, the subsequent cleaning difficulty is reduced, and the operating pressure of the operator is reduced. During the grinding process of the bearing internal grinding machine in the utility model, the grinding head generates heat due to friction, the temperature rises, and the grinding head is easily damaged due to the high temperature.
