Description
Technical Field
The invention relates to the technical field of machining, in particular to a machining machine tool for the peripheral surface of a ring with a built-in cylinder.
Background
In many machines, there is a circular ring of components (e.g., inner and outer races of a bearing) that is a component of the bearing. In the process of machining the ring, the inner circumferential surface and the outer circumferential surface of the ring need to be machined by a machine tool. When the existing machine tool is used for fixing a workpiece, the workpiece is closed by clamping jaws to realize fixation, when the clamping mode is used for processing the outer circumference of a ring, the outer circumference of the processed ring is coaxial with a machine tool spindle, but the inner circumference of the ring is difficult to keep coaxial with the machine tool spindle in the clamping process, so that the ratio of the coaxiality of the inner circumference and the outer circumference of the processed ring which does not meet the requirement is high, and the ring is a waste product when the coaxiality deviation of the inner circumference and the outer circumference of the ring does not meet the requirement in the bearing manufacturing process; in addition, the outer peripheral surface of the ring needs to be occupied during clamping, so that the processing of the outer peripheral surface of the ring can be completed only by twice processing (namely, one end is clamped to process the other end, then the other end is taken down to change the direction of the ring, and the other end is clamped to process one end), time is wasted during clamping by twice processing, and the two processed parts generate a non-coaxial phenomenon, so that the quantity of products with unqualified quality is large.
