Honing head for platform screen

Abstract

The invention discloses a honing head for a platform screen in the technical field of automobile part processing. The honing head comprises an upper end cover, a lower end cover, oil stone pressure springs, a support, coarse honing oil stones, refined honing oil stones, screen honing stones, an inner shaft and an outer shaft; the outer shaft is sleeved on the inner shaft; the inner shaft is arranged in a center hole of the support; the coarse honing oil stones, the refined honing oil stones, and the screen honing stones are uniformly and crosswise arranged on clamp grooves distributed on a circumference of the support uniformly; the oil stone pressure springs are arranged in clamp grooves radially distributed on the upper end cover and the lower end cover; and the edges of two sides of the coarse honing oil stones, the refined honing oil stones, and the screen honing stones are fixed in the clamp grooves of the upper end cover and the lower end cover and are connected with the oil stone pressure springs; and the upper end cover and the lower end cover are fixed at two ends of the support. The coarse honing oil stones, the refined honing oil stones, and the screen honing stones canbe gathered on one honing head, the honing head or a honing machine tool is not needed to be replaced during conversion among coarse honing, refined honing and screen honing, the processing quality and efficiency of the platform screen can be effectively improved and the requirement of high-precision platform screen honing can be met.

Description

technical field [0001] The invention relates to a device in the technical field of auto parts processing, in particular to a platform anilox honing head for restoring the anilox accuracy of the cylinder bore of an automobile engine cylinder block and the cylinder liner platform. Background technique [0002] Platform honing is an important processing technology to restore the dimensional accuracy, shape accuracy and surface roughness of the cylinder bore and cylinder liner of the engine block, and to form a platform texture. The generation of platform texture is beneficial to improve the lubrication effect of cylinder bore and cylinder liner surface, and significantly reduce the wear of cylinder bore surface. Practical application shows that compared with ordinary honing engine, engine lubricating oil consumption after platform honing is reduced by 50% ~83%, the running-in period is shortened by 33%~50%, the torque is increased by 5%, the service life is increased by 10%~20%...

AI Technical Summary

Problems solved by technology

At present, there is no honing head that can meet the needs of rough honing, fine honing and brush honing at the same time. During the conversion process of rough honing, fine honing and brush honing, the honing head must be replaced once or twice, and sometimes even the honing machine tool needs to be replaced , which seriously affects the processing accuracy and processing efficiency, and cannot meet the needs of high-precision platform texture

[0003] After searching the existing technology, it was found that the utility model patented cylinder platform anilox honing tool (patent number ZL200920128545.5), which was authorized and announced on June 2, 2010, mentioned a kind of rough honing stone and fine honing stone The integrated honing head avoids the replacement of the honing head during the transition from rough honing to fine honing, but brush honing cannot be performed with this honing tool, which is difficult to meet the needs of high-precision platform anilox honing
