Problems solved by technology
The shortcoming of this processing method is: 1, production efficiency is low, There are only two tolerances, which is very difficult to process. After rough turning, multiple test runs are required, and the inner diameter micrometer is used to measure the test run. The requirements can only be met after repeated repetitions. The efficiency is low; 2. The technical requirements for operators are high. It is difficult to guarantee the qualification rate of batch products, and the labor intensity is high, and the labor cost is high; 3. The scrap rate is high, The tolerance is easy to exceed the tolerance and produce waste products, such as operation errors, measurement deviation, thermal deformation and other factors can affect the tolerance range

Embodiment Construction
[0011] The present invention will be further described below in conjunction with accompanying drawing:
[0012] Depend on figure 1 Shown, a kind of pulley batch processing method comprises the following steps:
[0013] (1) Choose an ordinary lathe, such as a CA6140 lathe, to process each surface, and process all dimensions except the inner circle surface A on the right to meet the requirements of the drawing, and leave the amount at A on the inner circle surface on the right That is processed to At this time, it is necessary to ensure that the remaining amount is uniform, otherwise the thickness of the chip is inconsistent, and the size of the "cutting knife" is irregular, which will affect the processing accuracy of the subsequent steps. high. After processing, check the vernier clamp.
[0014] (2) Weld copper blocks on the working surface of the claws of the CNC lathe (such as CAK6150) to make copper soft claws that do not damage the workpiece, and then use the inner h...

The invention relates to a pulley batch machining method which mainly solves the problems that an existing pulley is low in machining efficiency, high in rejection rate and high in labor intensity of workers. The method is characterized by including the following steps that (1) all faces are machined through a common lathe, all the faces except a right inner circular face (A) are machined to the sizes meeting the requirements of a drawing, and the right inner circular face (A) is machined to ; (2) copper flexible jaws are welded to the work face of a clamping jaw of a numerical control lathe, and then finish turning is carried out on the inner surfaces of the copper flexible jaws through an internal bore turning tool; (3) the right inner circular face (A) is machined to through the numerical control lathe at a constant speed. When the method is adopted to machine pulleys, the fact that the dimensional tolerance of the products is within the required range is guaranteed, labor intensity is reduced, machining time is saved, efficiency is improved, and the rejection rate is reduced.
Description
technical field [0001] The invention relates to the field of machinery, in particular to a batch processing method for pulleys. Background technique [0002] A pulley is required for the door part of the P70 railway freight car, and the middle hole of the pulley needs to be inlaid with a rolling bearing. The specific size is The tolerance is only 0.02mm (commonly known as "two lines"). At present, this pulley is usually processed by CA6140 lathe, that is, the right end ( Hole end) Each size is turned into shape at one time, and then turned around and turned to turn the left end. The shortcoming of this processing method is: 1, production efficiency is low, There are only two tolerances, which is very difficult to process. After rough turning, multiple test runs are required, and the inner diameter micrometer is used to measure the test run. The requirements can only be met after repeated repetitions. The efficiency is low; 2. The technical requirements for operators ar...
