Example Embodiment

[0021] Example 1

[0022] A process for processing deep mounting holes for slewing ring bearing rings, which is used to process mounting holes with a diameter of φ45 required for the finished product. The steps include: figure 1 As shown, the first hole is processed as a through hole, and the method for processing the first hole is to use a flexible drill that meets the requirements to drill directly from side B at one time. The unit of dimensions in all drawings is mm.

[0023] Such as figure 2 As shown, the remaining holes are first processed with a φ42mm U drill, the processing depth is h2, the height of the slewing bearing is H, H>h2, and the processing depth h2 is about half of the end face height.

[0024] Such as image 3 As shown, after processing, the turning material is aligned with the specified reference and then the first hole is aligned to determine the zero position (the starting position of processing, the angle is 0° at this time), and then the hole is drilled with ...

Abstract

The invention belongs to the technical field of process for machining bearing mounting holes, is applied to the field of deep hole machining of slewing bearing products, and particularly relates to aprocess for machining a deep mounting hole of a slewing bearing ring. The process comprises the following steps: machining a first hole into a through hole and machining other holes by using a U drill, wherein the machining depth is h2, the height of the slewing bearing is H, H>h2, other holes are turned over and aligned after being drilled for the first time, then the holes are drilled through the U-shaped drill, chambering machining is conducted through a flexible drill, and finally the size required by a finished product is achieved. The stability of the machining process and the stabilityof the product quality can be guaranteed.
