Description
Technical field
The utility model is related to machining technology field, and in particular to a kind of machining tools for inner bores, particularly uses
The honing head processed in irregularly-shaped inner hole.
Background technology
Honing technique is mainly used in the finished machined in hole, is used as the grinding tool on honing machine, the structure and chi of honing head
Very little very big on honing precision influence, processing object is different, and the structure of honing head is also different.
However, the honing mandrel construction pattern that existing Honing process is used is more single, honing technique also comparative maturity.Tradition
Honing head oil stone base, oilstone etc. arranged along honing head axis direction, be suitable only in the cylinder of the single aperture of honing standard
Hole, it is impossible to honing irregularly-shaped inner hole, such as cydariform, waveform endoporus, but these irregularly-shaped inner hole type components are in some special operation conditions
With relatively common in the products such as oil cylinder, military project or locomotive special type cylinder sleeve of engine.Current such product endoporus
Can only manual polishing or using formed grinding wheel grinding, machining accuracy is poor, and processing efficiency is low, and surface quality is difficult to precise control, and
And such grinding can not process platform reticulate pattern, batch production difficulty is larger, it is impossible to meet drawing requirement, influences product usability
Energy.Through the literature search discovery to prior art, it is found that the U of Chinese invention patent CN 205465654 are disclosed in a kind of abnormity
