Processing method of inner ring

Abstract

The invention discloses a processing method of an inner ring, which comprises the following steps: S1: forging, forging and processing to form a blank according to the processing drawing; S2: rough processing; S3: UT flaw detection; S4: lathe on both sides of the outer circumference of the part One annular groove, the cross section of the annular groove is parallelogram, the depth of the annular groove extends along the radial direction of the part, and the two annular grooves are arranged symmetrically; S5: Drill some connecting holes on the two ends of the part, drill The direction of the hole depth extends along the axial direction of the part, and the drilling depth is less than the distance between the outer surface of the annular groove and the end face of the part; S6: Quenching and tempering; S7: Finishing of the outer circumference of the part; S8: Chamfering according to the drawing , and the connecting holes on the removed parts are processed according to the drawing size; S9: Pack and store.

Description

Technical field[0001]The present invention relates to a processing method of an inner ring.Background technique[0002]Prior artfigure 1 The billet processing shown is asfigure 2 When the inner ring shown, since the upper portion of the inner ring needs to open two shaped grooves, it is currently processed by the lathe, and only one of the shaped grooves can be processed each time, and the parts are completed. After replacing the other, and the four-claw chuck is fixed when the part is fitted, and since the four-claw chuck has extremely high clamping force, and the part is thin wall, thereby one of the shaped grooves When the other is completed, the part is easily deformed under the very high clamping force, and the part is easily deformed after the machine, and is due to the shaped groove, and therefore, in the carbut, the amount of feed is continuously adjusted, and in order to reduce The deformation needs to constantly adjust the feed speed, so the processing efficiency is low.Inve...

Problems solved by technology

[0002] In the prior art, for figure 1 The blank shown is machined as figure 2 For the inner ring shown, since two special-shaped grooves need to be opened on the upper and lower parts of the inner ring, it is currently processed by a lathe, and only one of the special-shaped grooves can be processed at a time. After processing one of them, the part The other one is processed after changing the direction, and the four-jaw chuck is used to fix the part when clamping. Since the four-jaw chuck has extremely high clamping force and the part is thin-walled, one of the special-shaped grooves is processed When another piece is processed after completion, under the action of extremely high clamping force, the part is easily deformed after it leaves the machine tool. In addition, because it is a special-shaped groove, it is necessary to continuously adjust the feed rate during the process of turning chips, and in order to reduce Deformation requires constant feed rate adjustments, resulting in inefficient machining
