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

Embodiment 1

[0024] The inner ball cage is cylindrical, and the inner hole processing method of the inner ball cage includes the following steps:

[0025] A. Material preparation: Prepare the cast inner ball cage blank:

[0026] B. Tapered hole processing: Clamp the inner ball cage blank on the lathe. When the tool is close to the end of the inner ball cage blank, the tool realizes longitudinal feed and horizontal feed at the same time. After processing, the inner hole is conical. semi-finished products;

[0027] In the step B, the cutting speed of the cutting tool is 2 cm / 10 seconds.

[0028] The speed of the longitudinal feed of the tool in the step B is 0.5 cm / 10 seconds.

[0029] C. Secondary processing: The semi-finished product is turned around and clamped on the lathe. When the tool is close to the end of the semi-finished product, the tool realizes lateral feed, and the secondary semi-finished product with a straight hole in the inner hole is obtained after processing;

Abstract

The invention provides an inner hole processing method of an inner ball cage, which belongs to the technical field of machinery. It solves the problem of poor stability existing in the prior art. The inner hole processing method of the inner ball cage includes the following steps: A, material preparation: the cast inner ball cage blank is used for standby: B, tapered hole processing: the inner ball cage blank is clamped on the lathe, when the tool is close to the inner After the end of the blank of the ball cage, the tool realizes longitudinal feeding and horizontal feeding at the same time, and after processing, a semi-finished product with a conical inner hole is obtained; C. Secondary processing: the semi-finished product is turned around and clamped on the lathe, when the tool is close to the semi-finished product end After the first part, the tool realizes lateral feed, and after processing, a secondary semi-finished product with a straight hole is obtained; D. Finishing: The set machining allowance is removed during the lateral slow feed of the tool to obtain the inner ball cage of the finished product. The inner hole processing method of the inner ball cage has high stability.

Description

technical field [0001] The invention belongs to the technical field of machinery and relates to an inner hole processing method 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 in the shape of 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. 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 ball cage to break. Contents of the invention [0004] The object of the present invention is to solve the above-mentioned problems in the prior art, and provide a high-efficienc...
