Measuring device of ring rolling machine

Abstract

The invention discloses a measuring device of a ring rolling machine. The measuring device comprises a fixed seat, a guide rod, a front beam, a rear beam, a measuring wheel and a front cover, wherein the fixed seat is fixedly arranged on a ring rolling machine rack; the guide rod is in sliding fit with the fixed seat; the front beam and the rear beam are arranged at the two ends of the guide rod; the measuring wheel is arranged on the front wheel; the measuring device is characterized in that the front beam is provided with a groove for accommodating the measuring wheel and rear half shaft holes which are formed in two side faces of the groove for mounting a stationary shaft of the measuring wheel; the front cover is fixedly arranged on the front beam and is provided with a through hole for penetrating through the measuring wheel and front half shaft holes; the front half shaft holes are formed in two side faces of the through hole for mounting the stationary shaft of the measuring wheel; the front half shaft holes and the rear half shaft holes form complete shaft holes; the stationary shaft of the measuring wheel is provided with a stationary shaft step of which the diameter is greater than that of the shaft holes; a bearing is sleeved on the stationary shaft of the measuring wheel, so that one side of an inner ring of the bearing is in contact with the stationary shaft step; a spacer bush is sleeved on the stationary shaft of the measuring wheel to come into contact with the other side of the inner ring of the bearing; and the measuring wheel is sleeved on the outer ring of the bearing.

Description

technical field [0001] The invention relates to the real-time measurement of the diameter of a ring during the ring rolling process of a ring rolling machine. Ring rolling machines are used to manufacture high-quality seamless ring forgings, such as: bearing rings, ring gears, flanges, hubs, thin-walled barrels, etc. Background technique [0002] In the process of ring rolling (also known as ring rolling, ring rolling), the diameter of the ring is constantly increasing, and it is necessary to measure the diameter of the ring in real time to control the rolling process. Ring rolling machine (also known as ring rolling machine, ring rolling machine) is an effective equipment for ring rolling. Ring rolling process see figure 1 . During the ring rolling process, the ring piece 4 rotates under the drive of the main roller 1 and the cone roller 5, and drives the measuring wheel 6 to rotate. The front beam 8, the back beam 16, the guide rod 10, the measuring wheel 6 etc. form t...

Problems solved by technology

Although this method can lubricate and cool the measuring wheel during the ring rolling process, it is difficult to process deep holes

The current structure of the measuring wheel section makes the axial dimension not compact
