Embodiment

[0040] An ideal cylindrical hole honing head device, its structure is as follows Figure 1-4 As shown, the device includes a grinding head frame 1, a feed rod 2, a whetstone base 3 and a whetstone 4. Wherein, the grinding head frame 1 is a hollow cylindrical structure, and base holes are arranged alternately in the circumferential direction of the grinding head frame 1. There are two rows of base holes, and the adjacent base holes are arranged alternately up and down. The feed rod 2 has a conical structure and is located at the center of the grinding head frame 1 . The oil stone base 3 is installed in the base hole and can slide along the guide groove of the base hole. The whetstone base 3 used is a wedge-shaped block, and the inclined surface on the inside fits the tapered surface of the feed rod 2 . The oil stone 4 is fixed on the oil stone base 3, and the oil stone 4 used is a sand bar.

Abstract

The invention relates to a perfect cylindrical hole honing head device and a structure method thereof. The device comprises a hollow cylindrical structure, a honing head rack, a feeding rod, oilstone bases and oilstones, base holes are peripherally and alternately arranged on the honing head rack in a staggered manner, the feeding rod is disposed in the center of the honing rack, the oilstone bases are mounted in the base holes, and the oilstones are fixed onto the oilstone bases. The structure method includes computing lengths of honing head stroke ranges and lengths of the oilstones which correspond to various curves; computing mutual position relation among the oilstones; and designing and manufacturing the honing head device with the oilstone distribution meeting a result of the last step. The distribution of the oilstones and acting areas of the oilstones are adjusted, and effects that tracks of grains are generally distributed uniformly and honing quantity of wall materials of the cylinder hole tends to be uniform are achieved.

Description

technical field [0001] The invention relates to a honing process improvement method and a honing head structure device for improving the cylindricity of a cylinder bore, in particular to a honing head structure that aims at the defects in the motion track distribution of the existing honing head and adopts a dislocation distribution structure of whetstone strips to realize the uniformity of the honing track of the whetstone distribution, thereby improving the process control method and device of cylinder bore machining accuracy. Background technique [0002] In the engine manufacturing process, honing is the most important process to ensure the final accuracy of the cylinder bore. The honing head is loaded with a honing oil stone, which drives the oil stone to continuously reciprocate during honing, thereby precisely cutting the material of the cylindrical hole. Therefore, the structure and motion performance of the honing head will have a direct impact on the honing accura...
