The invention relates to a repairing and grinding lathe of a large-size rolling bearing channel, comprising a lathe body, wherein the lathe body is a plane bracket containing more than three supporting points; the end faces of the supporting points of the bracket are provided with a vertical plate; and the end part of each supporting point of the lathe body is provided with a positioning and supporting mechanism used for positioning a workpiece; the positioning and supporting mechanism consists of an adjustable radial supporting nail for centering the workpiece and a supporting plate for realizing the axial positioning of the workpiece; the supporting nail is connected to the vertical plate of the lathe body, and the supporting plate is connected below the end part of the lathe body; one side of the lathe body is provided with an oscillating mechanism for repairing and grinding the workpiece, the oscillating mechanism comprises a head swinging motor connected with a head swinging box,and the head swinging box is connected with an oilstone cutter used for processing the workpiece; and the other side of the lathe body is provided with a hand-push handle for ensuring that the lathe body rotates along the surface of the workpiece. The invention has the advantages of compact and simple overall structural design, accurate working positioning, convenient use and low production cost.
Description
technical field [0001] The invention relates to the field of mechanical engineering, in particular to a repairing and grinding machine tool for a large rolling bearing groove. Background technique [0002] Large bearings are used in excavators, turntables of large cranes, and turrets of tanks. The harsh working environment of these machines will aggravate the failure of the bearing raceway (groove) surface. In the maintenance of large bearing raceways, super-finishing the raceway is an effective process. At present, large-scale angular contact ball bearing rolling (groove) track super-finishing processing adopts large-scale bearing rolling (groove) track super-finishing machine tools. However, this machine tool has a huge structural size and is expensive. It is not practical to repair bearings, especially on-site repairs. Contents of the invention [0003] The present invention solves the problems of large structural size, high price and inconvenient on-site maintenance...
