High-precision bearing forge piece machining method

Abstract

The invention discloses a high-precision bearing forge piece machining method. The machining method comprises the following steps of workblank detection, part reference machining, other end face machining, inner diameter cutting of a bearing outer ring, three times of detection, polishing and four times of detection. According to the machining method, the appearance and the interior of the workblank are detected before production, defective products are screened timely before machining, resource waste is reduced, and the qualified rate of finished products is improved. According to the machining method, a way of combining rough machining and finish machining is adopted for machining, so that the condition that the one-time cutting amount is large is avoided, poor tool vibration is reduced,and the service life of a tool is ensured; in the machining method, in the machining process of a whole lathe, cooling liquid at the temperature of 18-22 DEG C is adopted for cooling the machined part, the temperature difference change of the environment is ensured, the influence of the temperature on part machining is reduced, and machining precision is improved. Paint spraying marks are adoptedfor the defective products, so that distinguishing of the defective products is facilitated, and outflow of the defective products is effectively avoided.

Description

technical field [0001] The invention relates to the processing field of bearing outer rings, in particular to a processing method for high-precision bearing forgings. Background technique [0002] Processing refers to the process of making qualified parts from a blank. The outer ring of the bearing is one of the important components of the bearing. The outer ring of the bearing is usually fixed on a fixed part such as the bearing base for fixing, the inner ring of the bearing rotates, and the outer ring of the bearing The size of the transfer is relatively high, and the assembly of the bearing is usually installed in an oil bath. In the prior art, the bearing is usually processed by a lathe. During the processing, a large amount of heat is generated, which causes the outer ring of the bearing to deform and clamp Loose, resulting in unqualified dimensions, tool vibration and other defects. In the processing process of the prior art, one-time processing is usually adopted, the...

[0002] Processing refers to the process of making qualified parts from a blank. The outer ring of the bearing is one of the important components of the bearing. The outer ring of the bearing is usually fixed on a fixed part such as the bearing base for fixing, the inner ring of the bearing rotates, and the outer ring of the bearing The size of the transfer is relatively high, and the assembly of the bearing is usually installed in an oil bath. In the prior art, the bearing is usually processed by a lathe. During the processing, a large amount of heat is generated, which causes the outer ring of the bearing to deform and clamp Loose, resulting in unqualified dimensions, tool vibration and other defects. In the processing process of the prior art, one-time processing is usually adopted, the cutting volume is large, and the load of the lathe is relatively large, which easily leads to tool vibration and tool chipping , affect the processing size and tool life, lack of handling methods for defective products in the production process, the on-site operating environment is complex, which can easily lead to the outflow of defective products, customer complaints, and affect the reputation of the company. Most companies consider the cost , there is no detection of blank parts. Usually, the processing personnel check by themselves before processing, but they can only check the external defects. The internal defects are unpredictable. It is very easy to find the internal defects after the processing is completed, which is a waste of resources while increasing business costs
