Abstract

The invention relates to the field of bearing ring manufacturing and measuring devices and aims at providing a cold rolling measuring and controlling device for a workblank of a bearing ring. The cold rolling measuring and controlling device for the workblank of the bearing ring comprises a fixed seat, a sliding seat connected with the fixed seat through a transverse sliding rail, a measuring head fixedly connected with the sliding seat, a collision mechanism driving the measuring head to collide against the outer periphery of the workblank of the bearing ring, and a measuring and controlling device. When the cold rolling measuring and controlling device for the workblank of the bearing ring is used, the collision mechanism pushes the measuring head to collide against the outer periphery of the workblank of the bearing ring, the outer periphery of the workblank of the bearing ring enables the measuring and controlling device to act through the measuring head and the collision mechanism along with the expansion of the outer diameter of the workblank of the bearing ring during the cold rolling, and when the outer diameter of the workblank of the bearing ring reaches the specified value, the measuring and controlling device transmits a signal to a controller and then the controller controls a bearing ring cold rolling device to stop and get out of the cold rolling state. The cold rolling measuring and controlling device for the workblank of the bearing ring is relatively high in measuring efficiency and measuring precision.

Description

technical field [0001] The invention relates to the field of measuring devices for manufacturing bearing rings, in particular to a measuring and controlling device for cold rolling blanks of bearing rings. Background technique [0002] Generally, bearing ring blanks are made by casting or forging; the invention of Chinese patent notification number CN 1243207A discloses a production method of rolling bearing ring blanks; in particular, it relates to the application of centrifugal casting technology in the manufacturing process of rolling bearing ring blanks. It organically combines multiple technologies of electric furnace steelmaking, centrifugal casting and bearing forging, so as to achieve the purpose of reducing the production cost and improving the quality of rolling bearing ring blanks. The dimensional accuracy of the bearing ring blank made by casting or forging is low and the machining allowance is large; the bearing ring blank can be manufactured with the bearing ri...
