The rotary composite push rod mechanism provided by the embodiment of the application is described in detail below by means of specific embodiments and application scenes thereof with reference to the accompanying drawings.
The inventor of the application finds in the practical process that the precision feeding honing push rod and the rough feeding honing push rod are easy to bend and deform due to stress in the working process due to the problem of self rigidity, so that the axis of the honing head cannot keep coaxiality with the axis of the rotary composite push rod mechanism, and further the machining dimensional precision, geometric shape precision and platform reticulation index of the machining surface cannot meet the requirements.
As shown in fig. 1 to 4, the present embodiment provides a rotary compound push rod mechanism for a honing machine, which includes a first honing stick 110, a second honing stick 120 and a stick deviation correcting mechanism 130.

Furthermore, since the second honing stick 120 is divided into at least two separate structures, the second honing stick 120 is less likely to bend than an integrated structure. In addition, the thrust ball bearing 133 is sleeved on the first honing stick 110 to support the first honing stick 110, so as to avoid bending deformation of the first honing stick 110, thereby ensuring accurate movement of the first honing stick 110.
