Description

Technical Field

[0001] The utility model relates to the technical field of honing machines, in particular to a double-feed honing head with a universal adjustment function. Background Art

[0002] A honing machine is a grinding machine that performs precision machining on the surface of a workpiece. Its main principle is to use the oilstone on the circumference of the honing head on the honing machine, and expand the oilstone radially through an expansion mechanism, so that it is pressed against the wall of the workpiece hole to make contact, while the honing head rotates and reciprocates, and the part does not move; or the honing head only rotates, and the workpiece reciprocates, thereby achieving honing. In the existing technology, the expansion and contraction methods of the honing head are generally divided into two modes: constant pressure feed and quantitative feed. Among them, constant pressure feed is generally achieved by hydraulics or springs, and quantitative feed is usually achieved by servo motors, stepper motors or other intermittent mechanisms. Manual feeding can also be regarded as quantitative feed.

[0003] The existing honing head with a universal adjustment component can improve the geometric accuracy and dimensional accuracy of the honed parts and improve the product qualification rate. However, the honing machine grinds the inner surface of the machined hole by rotating the honing head. The component responsible for grinding the machined hole is called an oilstone. This grinding process inevitably causes wear and tear on the oilstone, so the oilstone needs to be replaced regularly. The oilstone in the existing technology is usually an irregular flaky structure. Once the grinding surface is damaged, it is not easy to replace, which affects its use. Therefore, a double-feed honing head with a universal adjustment function is needed. Utility Model Content
