Problems solved by technology
In the existing ball cage cage processing technology, after rough machining, there are three processes of surface grinding, demagnetization, and front window full inspection. In the subsequent processing, the plane after surface grinding is used as the reference plane. Therefore, Before each process is processed, it is necessary to manually identify the reference plane, and the identification method only relies on the size of the chamfer, which is easy to identify errors due to human reasons, resulting in serious consequences of crashes in the subsequent process; at the same time, the original surface grinding process uses a vertical axis round table The disadvantage of surface grinding is that the processed product affected by the state of the product itself cannot change the state of the parallelogram, which affects the processing accuracy

Embodiment Construction
[0021] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.
[0022] Such as figure 1 As shown, the processing technology of the ball cage cage, the specific steps are as follows:
[0023] a. Manufacture blanks: first inspect the incoming raw materials, reject unqualified raw materials, put the raw materials into the forging equipment, and make a rectangular parallelepiped blank by forging;
[0024] The forged blank is subjected to a normalizing process. In the normalizing process, the blank is kept at 700°C to 900°C for two hours and then cooled by spraying water. After normalizing, the incoming material is inspected and unqualified ones are eliminated. Preferably, the normalizing temperature in this embodiment is 750°C.
[0025] b. Rough machining: Put the blank into the machine ...

The invention provides a process for machining ball cage retainers, and belongs to the field of operation. By the aid of the process, technical problems of sever results of collision in later working procedures and the like due to requirements on artificially identifying machining reference surfaces in existing processes for machining ball cage retainers and easiness in causing identification errors for artificial reasons can be solved. The process for machining the ball cage retainers includes particular steps of a blank manufacturing, b rough machining, c double-plane grinding technologies, d finish machining, e polishing and f warehousing. The process has the advantage that the ball cage retainer machining efficiency and precision can be improved.
Description
technical field [0001] The invention belongs to the field of operation, and relates to a ball cage cage, in particular to a processing technology of a ball cage cage. Background technique [0002] The ball cage is also called "constant velocity universal joint" and is an important part in the transmission system of a car. Its function is to transmit the power of the engine from the transmission to the two front wheels to drive the car at high speed, which requires high precision. [0003] The ball cage cage is one of the key components of the ball cage, which plays the role of transmission. At present, the ball cage cage adopts an automated production process to ensure accuracy. In the existing ball cage cage processing technology, after rough machining, there are three processes of surface grinding, demagnetization, and front window full inspection. In the subsequent processing, the plane after surface grinding is used as the reference plane. Therefore, Before each proces...
