Machining method for inner hole of inner ball cage

Abstract

The invention provides a machining method for an inner hole of an inner ball cage, and belongs to the technical field of machinery. The problem of poor stability in the prior art is solved. The machining method for the inner hole of the inner ball cage comprises the following steps that A, materials are prepared, specifically, an inner ball cage blank formed through casting is reserved; B, a conical hole is machined, specifically, the inner ball cage blank is clamped on a lathe, after a cutter is close to the end of the inner ball cage blank, longitudinal feeding and transverse feeding are achieved at the same time through the cutter, and a semi-finished product with a conical inner hole is obtained after machining; C, secondary machining is carried out, specifically, the semi-finished product is turned around and clamped to the lathe, after the cutter is close to the end of the semi-finished product, transverse feeding of the cutter is achieved, and a secondary semi-finished product with an inner hole being a straight hole is obtained after machining; and D, finish machining is carried out, specifically, the set machining allowance is removed in the transverse slow feeding processof the cutter, and the finished inner ball cage is obtained. The machining method for the inner hole of the inner ball cage is high in stability.

Description

Technical field [0001] The invention belongs to the technical field of machinery and relates to a method for processing an inner hole of an inner ball cage. Background technique [0002] The inner ball cage is cylindrical. In order to improve the connection stability between the inner ball cage and the intermediate shaft, the inner cavity of the inner ball cage is a straight hole with relatively high precision. [0003] In the existing industrial production, the inner cavity of the inner ball cage is usually completed by two processes of rough turning and fine turning. Because the length of the inner ball cage is relatively long, turning directly along the transverse feed will cause the strength of the inner ball cage to decrease. Cause the inner ball cage to rupture. Summary of the invention [0004] The purpose of the present invention is to provide an inner hole machining method of an inner ball cage with high efficiency and high stability in view of the above-mentioned problems...

Problems solved by technology

[0003] In the existing industrial production, the inner cavity of the inner ball cage is usually completed by two processes of rough turning and fine turning. Since the length of the inner ball cage is relatively long, the turning operation directly along the transverse feed will lead to a decrease in the strength of the inner ball cage. In severe cases, it will cause the inner cage to break
