Technical Field

[0002] In the structure of hydraulic pumps and motors, the cylinder block and the oil distribution plate spherical pair are one of the most important friction pairs in hydraulic pumps. Both parts are spherical structures. Figure 1 As shown, the oil distribution plate is Figure 2 As shown in the figure, in the traditional process route, whether it is the outer spherical surface or the inner spherical surface, manual grinding is mostly used as the final finishing process. However, manual grinding has the disadvantages of low efficiency and unstable quality, which becomes the bottleneck of the finishing process. At the same time, the precision level of the spherical surface matching of the parts will affect the performance indicators such as flow and pressure, and even the wear between the two will reduce the efficiency and life of the whole pump. Therefore, the spherical surface processing method is very important. In particular, the problem of abnormal wear of the two friction pairs is serious, which has a great impact on the pumping function and volume rate of the hydraulic pump, resulting in the overall qualified rate of the friction pairs of the hydraulic pump being less than 10%, and it is impossible to realize the mass production of the hydraulic pump.
