The honing fixture needs to be designed according to the honing mode and the type of honing machine.
Honing high-precision parts on a vertical honing machine generally adopts a honing mode that a honing head is fixed and the parts float. The honing head has small jumping amount, the part is arranged on the full-floating clamp, and honing is performed through self-guiding of the honing head, so that concentricity of the honing head and the honing hole of the part can be ensured, and further honing precision is ensured. When the honing head is used for fixing and the part is in a floating honing mode, the gravity center of the part is required to be located on the axis of the honing hole, and in the radial direction of the hole, the moment of inertia of the part along the axis is the same. For shaft parts, because the shaft parts meet the condition of good floatability, high honing precision can be obtained without a counterweight. For honing of eccentric and asymmetric parts, the balance weight is required to be carried out, and the balance weight is required to ensure that uniform rotational inertia is obtained in the radial direction of the whole hole, so that the honing part is ensured to have good floatability, and finally, the precision of honing the hole is ensured to reach the design requirement.
In order to simplify the design of the balance weight honing fixture, the conventional vertical honing machine generally adopts a balance weight mode in the longitudinal direction, but the balance weight mode does not obtain uniform moment of inertia in the radial direction of the whole hole, so that the roundness, cylindricity, size and other precision of the honing hole cannot meet the design requirement.
