Description

Technical Field

[0001] The invention belongs to the technical field of bearing retainer processing, and in particular relates to a new processing method for a bearing retainer. Background Art

[0002] The bearing cage, also known as the bearing retainer, is an important component of the bearing. Its main function is to evenly separate the rolling elements, prevent the rolling elements from colliding and rubbing against each other, and guide the movement of the rolling elements in the bearing to ensure the smooth operation of the bearing. The bearing cage is usually made of metal, plastic or composite materials, and its design and material selection will affect the performance, life and reliability of the bearing. Different types of bearing cages have their own characteristics and scope of application to meet the needs of various mechanical equipment.

[0003] In the traditional manufacturing process of bearing retainers, broaching machines are usually used for processing. This processing method has many shortcomings, such as relatively low production efficiency, high scrap rate, and difficulty in ensuring the passivity of the four corners R and inclination. At the same time, the processing accuracy and dimensional controllability need to be improved. Summary of the invention

[0004] The purpose of the present invention is to provide a new processing method for a bearing retainer to solve the problems raised in the above background technology.

[0005] To achieve the above object, the present invention provides the following technical solution: a new processing method for a bearing retainer, comprising the following steps:

[0006] S1. Fix the bearing retainer to be processed on the workbench of the five-axis machining center;

[0007] S2. Use the programming software of the five-axis machining center to compile the corresponding machining program according to the design drawings and machining requirements of the bearing cage;

[0008] S3, select a suitable tool and set processing parameters;

[0009] S4. Start the machining program through the control system of the five-axis machining center, so that the five axes X, Y, Z, A, B (or C) of the five-axis machining center are simultaneously linked;

[0010] S5, perform rough machining to remove excess material, followed by fine machining to ensure the accuracy of the inclination and the R of the four corners;

[0011] S6. After processing is completed, the bearing retainer is subjected to final inspection to confirm that all dimensions, accuracy and surface quality meet the standards.

[0012] As a preferred implementation, a precision measuring tool is used during the processing to monitor the processing accuracy in real time to ensure that the dimensions meet the design requirements.

[0013] As a preferred implementation, the machining parameters of the tool include cutting speed, feed rate, tool path, etc.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] In the present invention, five-axis linkage processing significantly improves processing efficiency and shortens production cycle; linkage processing reduces errors of workpieces in multiple clamping and reduces scrap rate; four-axis R shape and inclination can be precisely controlled and qualified rate is greatly improved; the high-precision performance of the five-axis machining center ensures consistency of machining accuracy and size; flexible machining capability enhances controllability of product size and adapts to production requirements of bearing retainers of different specifications. In summary, the five-axis linkage processing of the five-axis machining center can significantly improve production efficiency, reduce scrap rate, achieve 100% qualified R of four corners, and significantly improve machining accuracy, which has good industrial application prospects.
