Honing head device and honing machine provided with same

Abstract

The invention discloses a honing head device and a honing machine provided with the same, wherein the honing head device comprises a first connecting shaft, a floating body and a second connecting shaft; the floating body is positioned between the first connecting shaft and the second connecting shaft and is slidably connected with the end face, close to the floating body, of the first connecting shaft and the end face, close to the floating body, of the second connecting shaft respectively; the sliding direction of the floating body on the end face, close to the floating body, of the first connecting shaft is vertical to that on the end face, close to the floating body, of the second connecting shaft. According to the honing head device disclosed by the invention, the floating body is arranged to respectively translate along two mutually-vertical directions between the first connecting shaft and the second connecting shaft, so that a floatation and center alignment effect can be realized, a honing head is capable of aligning the center automatically when a to-be-machined hole is not coaxial to a main shaft of the honing machine, and meanwhile a honing effect is guaranteed. The honing head device is capable of effectively solving the problem that an elliptic opening is easily formed in the upper end of the hole when a honing cutter of an existing honing head structure is not coaxial to the to-be-machined hole.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to a honing head device and a honing machine with the same. Background technique [0002] Honing is a typical finishing process, which has been applied to the grinding of cylinder liners, connecting rod holes and hydraulic cylinder barrels of engines. In order to ensure that the ideal machining accuracy can be achieved when the hole to be machined and the honing tool are not in the same axis during honing, two methods of floating the honing head or floating the workpiece to be machined are usually used. When the honing head is used to process the hole to be processed in a floating manner, the honing head used usually adopts a universal joint and a joint head structure to realize a floating connection. However, when using a universal joint floating honing head for honing, when the honing tool is not in the same axis as the hole to be processed, the upper end of the universal joi...

Problems solved by technology

[0003] Based on this, it is necessary to provide a honing head device and a honing machine with the existing honing head structure for the problem that when the honing tool and the hole to be machined are not in the same axis, it is easy to cause an elliptical opening at the upper end of the hole.
