[0002] A honing machine is a type of machining equipment used for machining holes in the machining industry. Specifically, it is a grinding machine that uses a honing head to drill holes in workpieces and perform fine machining on the surface of the holes. It is mainly used to hone the holes of workpieces in a variety of large-scale manufacturing industries. There are two types of honing machines: vertical and horizontal. Among them, the horizontal honing machine has a longer working stroke and is suitable for honing deep holes. The honing head is placed horizontally and performs axial reciprocating motion. The workpiece is driven to rotate by the spindle. A center frame supporting the workpiece and a guide frame supporting the honing rod are provided in the middle of the bed. During the machining process, the oilstone of the honing head is radially fed under the action of the expansion and contraction mechanism to gradually machine the workpiece to the required size.

[0003] Usually, one end of the automatic knife expansion mechanism in the honing machine is fixedly connected to the equipment body, and the other end is arranged in a cantilever structure. The unsupported cantilever structure makes the automatic knife expansion mechanism of the honing machine easy to bend downward under the action of gravity, resulting in the hole processed by the equipment not meeting the processing requirements, or causing the equipment to malfunction due to excessive bending. Therefore, it is necessary to assume a support structure at the other end of the suspension. In the prior art, many support structures cannot be adjusted, or can only be adjusted in a single direction, and cannot be adjusted in multiple directions to adapt to different equipment conditions.
